Breast Cancer Lab Report Example | Topics and Well Written Essays - 750 words

Breast Cancer - Lab Report Example Acccording to studies,it is known that glycosylation is more pronounced in the breast cancer cells (Hakomori 1985). The reason for this is because of the increase in tne oligosaccharide structures (Hudis 2007).Such alterations might be identified through lectins which are the carbohydrate-binding proteins   an they have a very high specificity for the saccharides(Brooks and harris 2006).The lectins normally function as   the data mediators in the biological systems.In this case they interact with the glycoproteins glycolipids as well as the oligosaccharides(Nilsson 2007).They also bind specifically to the carbohydrate epitopes(Staffieri et al. 2012).The immunofluorescence method as well as the direct lectins cytochemistry   with the use of the   FITC-labeled lectins enables the visualization of the glycosylation’s impact on the therapies which targets the surface of the cells that bind to theHER2 receptors (Gabius 2009.The results from the histograms above (fig 1), ind icates the reason why the glycosylation’s intensity is higher in the sixth cell line when compared to that of the fifth cell line because of the different blocking agents used. In summary, further study needs to be done to clearly understand why there was a difference in the intensity of this two cell lines. It could be due to the above three mentioned reasons. Unfortunately, this study could not ascertain this.The reasons that could have resulted to the difference in the intesity could be due; firstly,the BSA could be a better blocking agent.

The Impact of Consumer Culture on the Advertisement of Oligo.Dx Assignment

The Impact of Consumer Culture on the Advertisement of Oligo.Dx - Assignment Example The representation of the body as promotional material and the connection of the same with the prevailing consumer culture of the catered customer base also is being critically evaluated. The advertisement does the extension of the product through directly noticeable images and also through critically relevant promotional text. The advertisement basically can be analyzed in two portions of which the first is the picture of a lady highlighting the cellulitis in her thighs. This image is captioned by the catchword, ‘90% of all women have cellulite’. This picture and the caption intend to cater for a broader range of customer base. This caption gives the reader a feeling that she is also included in the target group. This automatically adds to the range of the customer base. On the other side, this has an important link with the consumer culture as well. Featherstone (18-33) has opined that within a consumer culture, advertisement materials and other promotional media provides a proliferation of stylized images of the body. This has caused acute changes in the consumer culture of the society as the same has influenced their attention on both inner and outer body maintenance (Featherstone, 18-33). It should be taken into account that the advertisement of ‘Oligo. Dx’ caters to such a consumer base whose consumer culture is heavily influenced by these changes. Thus this caption along with the image contributes much towards the expansion of the consumer base. In this context, it can be well stated that the image and the caption in the advertisement successfully connect with the consumer culture and resultantly broadens the customer base for the product. In other words, these components the in the advertisement could successfully drag the reader into the customer base by utilizing the consumer culture pattern.  

Manufacturing Process of Bricks

Manufacturing Process of Bricks A brick has been a common construction material used everywhere for more than 6000 years, and has been in various shape, sizes and were made by mixing many different type of materials, each of them having their own advantage and disadvantage; and formed the basic structure and the back bone of many civilisations and was used in a wide range of buildings in centuries from building palaces, housing factories, in tunnels construction, water ways, bridges, making it the oldest manufactured building material. For centuries, the brick making process was done by hand, and involved clay being moulded and then dried in the sun until the industrial revolution when the process turned to mechanization. Today technological and mechanical advancement has helped to have a more complete knowledge of the raw material and its properties, and better control of firing, improvement in the kiln designs, all have contributed to the advancement of brick quality and has made contemporary bricks more efficien t and has improved the overall quality of the products. Today, brick is found in various materials and made in various shapes depending on the use. There are concrete brick, calcium silicate brick, clay brick and Adobe brick. See Appendix 1 This report will be looking at the technology associated with the manufacturing process of automated and traditional soil clay brick, adobe brick plain mud brick which are still use today in certain part of the globe or sometimes and slump brick- and the future of brick. PART ONE MANUFACTURING PROCESS OF AUTOMATED BRICK The first stage in the manufacturing process of the soil clay brick start with the selection of the raw material. RAW MATERIAL The main raw material in brick making is clay and it is one of the most abundant natural mineral materials on the planet. On earth, there is a wide range of clay which varies considerably in physical properties, colour, hardness and mineralogical content; making it difficult to pinpoint particular clay and say this is the best clay for brick making but they do, however, have certain properties in common. PROPERTIES and TYPES OF CLAYS Clay is complex material as individual, and their deposits is unique due to their specific modes of formation and physical characteristics, and are rarely present as pure minerals but rather are mixtures of the different clay types of one group or type normally being dominant. But the Clay entering in brick manufacturing must possess and fulfil some specific properties and characteristic such as the ability to be crushed and mixed with water to form a plastic material which can be moulded into various shapes; shrinkage or swelling percentage on firing, meaning when subject to appropriate temperatures the clay particles must fuse together; the bloating characteristics, meaning the percentage of water absorption; firing colour, meaning the colour of the brick after drying and percentage of fines produced upon crushing and fire strength and these physical properties determine their commercial value. The clays from which burnt bricks are made may be divided into three principal types, all of which have similar chemical compositions but different physical characteristics. They are: 2. A Surface Clays also called Alluvial and Drift Clays Found near the surface of the earth, may be the up thrusts of older deposits or of more recent, sedimentary formation; are readily worked and require little preparation. 2. B Shale clays or rocky clays Shale is sedimentary deposits clays that have been subjected to high pressures until they have hardened almost to the form of slate which are often difficult to work and necessitate the use of heavy machinery to extract but, may be brought into plastic condition by long weathering (i.e. by exposure to rain, frost and sun) or by crushing and grinding in water, and they then resemble ordinary alluvial clays in every respect. 2. C Fire Clays Fire clays are usually mined at deeper levels of the earth than other clays where they form the bed layer under seams of coal and have refractory qualities and a high degree of resistance to heat. MANUFACTURING PROCESS The process of making clay brick is generally uniform, although manufactures tailor their production to fit their particular raw materials. In general, the manufacturing process consists of essentially of six stages: Mining and Gathering raw materials Preparation of raw material (crushing, grinding, screening and mixing the raw materials) Making of the brick or Forming Process (forming, cutting and coating) Drying Curing ( firing and cooling) Packaging and storing Diagram of the industrial manufacturing process of clay bricks MINING and GATHERING RAW MATERIALS The choice of the mining method of clay will depend on the kind of clay, on the depth, thickness, hardness and physical geology of the clay location under the ground. The general method of extracting clay from the quarry is once or twice a year using heavy plant machinery to stock pile large amounts, so to ensure continuous brick production regardless of the weather conditions and because clays are rarely present as pure minerals but rather mixtures of the different clay types; laboratory testing of the clays from different parts of quarry will determine the characteristics of the layers and will be stock in separate different categories which will facilitate the blending of the raw materials. PREPATION OF THE RAW MATERIAL In the manufacturer, the clay rock is crashed and reduced in smaller particles, and then the material produced is screen through an inclined vibrating screening machine to control the particle sizes prior to water being added. During the screening, manufactures adjust and compensate the different variations in chemical composition and physical properties by blending clays from different locations and sources to fit their standard of the end product. Consequently, to fulfil their requirements of perfect clay for bricks making, or for the composition of the raw material to fulfil their standard, the different mixes and proportions of clay and chemical are blended together, prior to add water, as which of them affect the working properties of clays causing them to vary in their behaviour affecting the properties of the final product. At the same time, manufacture has standardized their end product and their manufacturing processes to limit variations in the processing and the inconsistency in end product. For instance, a clay brick that when cure turn white may be developed commercially because, by adding various minerals like oxide of iron will affect the propriety of the brick in such a way that when cure it will produce a red brick if also there is consistency in the manufacturing processes. Example: Clay containing from 5 to 8 % of oxide of iron will, under ordinary conditions of firing, produce a red brick; but if the clay contains 3 to 4% of alkalis, or the brick is fired too hard, the colour will be darker and purple. An excess of Alumina compound tending to make the colour lighter and brighter. FORMING OF THE BRICK The first step in forming process is to produce a homogeneous plastic clay mass work up into proper consistency by adding water to clay in a mixing chamber with one or more revolving shafts with blade extensions. After the kneading, the plastic clay mass is ready for forming. There are three different methods of shaping and forming brick: the stiff-mud process or extrusion process 6. A. The stiff-mud process or extrusion process In the stiff-mud process or extrusion process, the clay is mixed with just enough water to produce clay plastic mass with water in the range of 10 to 15 percent of the clay mass. Next, the clay is extruded through a die, producing a horizontal column of clay which passes by conveyor belt through an automatic wire cutter to create the individual brick. The cutter spaces and die size are precisely calculated to compensate for shrinkage during drying and firing. 6. B. Soft-mud process In the soft-mud process or moulded process, the clay contains too much water to be extruded. The plastic clay mass contain 20 to 30 percent of water per mass is used to produce brick either by hand or machine. In the machine driven soft-mud process, standard brick are produce in mass quantities as the machine replicate the hand-making process much quicker. 6. C. Hand making In the simplest form which is done by hand, the craftsman will produce one brick at the time by stuffing a lump of soft clay in a mould and the excess clay is stuff from the top of the mould and the brick is turned out. The mould is lubricated with either sand or water to prevent the brick from sticking in the mould. 6. D. The dry-press process In this process hydraulic or compressed air rams is used to press clay with very low plasticity, containing no more than ten percent of water by weight, into steel moulds under pressures from 500 to 1500 psi creating a very compact and dense brick. DRYING PROCESS Prior to the brick to be fired in the kiln, after the brick is formed using any of the method describes above, it containing 7 to 30 percent of moisture, depending upon the forming method. This moisture must be removed prior to the brick can be fired in the kiln otherwise, there will be formation of scum and certain mechanical defects from occurring or the brick will explode when the brick is subject to the intense heat of the kiln. This drying process which last about 18 to 40 hours, is normally done by placing the green brick in enclosed dryer which utilize excess heat supplied from the exhaust heat of kiln to maximize thermal efficiency. To ensure good result, devices are installed to measure and control humidity in the drying facilities. A. Firing After the drying, the brick are fired in furnace chamber called kiln for 10 to 40 hours, where there are subject to a temperature of ranging between 100 to 1200 degrees centigrade depending on clay type or material used and the type of finished brick required. During the process, clay particles and impurities will undergo changes as the temperature in the kilns rises. The remaining water in the brick will dry up or evaporate; unlike the metal, clay softens slowly and melts or vitrifies gradually in rising temperature. The clay molecules mass breaks down becomes soft enough to stick together; the mass becomes tight, solid and non absorbent giving the brick it texture and colour. To ensure a good product and avoid the brick to be deformed due to heat also called viscous fusion, kiln is fitted with sensors to control the temperature in the different stage the firing process. 7.A.1. What is a Kiln? In brief, kilns are just containers for heat; fuelled by natural gas, coal, sawdust, and methane gas from landfills or a combination of these fuels. There are many different types of kilns but the most common types are the continuous kilns (tunnel) which are always firing; they never cool and are capable of turning out large quantities of bricks at steady constant rate and the periodic (intermittent) kilns which are fired on an intermittent schedule. http://www.pottery-magic.com/pottery/history/bottle_kiln.htm PACKAGING Following the firing process is the packaging but prior to that the bricks are gradually cool down, for 10 hours for tunnel kiln and form 5 to 24 hours in periodic kiln, as the rate of cooling affect directly the final colour of the bricks. After the brick has cool downs, there are unload from the kiln; sorted, graded, packaged and place in a storage yard or loaded rail cars or truck of delivery. PART TWO MANUFACTURING PROCESS OF ADOBE CLAY BRICK The adobe brick, this type of earthen building materials has been around since the beginning of civilisation and has been the main building material for most of the civilisation. In our day, Adobe are mostly used in hot and dry climates and become the characteristic of the third world. Although this is a very old material, it manufacturing process hasnt change since. As with the soil clay brick the main ingredient which enter in the manufacturing process is clay and the manufacturing process start with the choice of the raw material. SELECTION OF RAW MATERIALS Adobe brick are made from a mixture of mud or clay and small pieces of straw or reeds, and are formed by hand and left in the sun to dry. The secret of make adobe bricks lays on the choice of the type of clay to use as it is made of surface clay soil. Although the bricks are made in rural area where there is no sophisticated laboratory for testing but prior using the clay it has to be tested. The testing of the clay can be done by filling 2/3 of a graded glass jar with the clay you plan to use, and then fill the jar with water and put a lid on. Shake the jar for about two minutes making sure the clay is totally mix up with the water then let the jar and the mix to sit overnight. After about 24 hours, examine the jar and its content; the clay would have broken up into two distinct bands of sand on the bottom and clay on the top. There should not be more clay than sand on the ration of 30 percent clay and 70 percent sand for an ideal adobe brick making clay. EQUIPMENT NEEDED Clay soil Measuring Tape Hammer Hand Saw 24 timbers Nails Shovel Bucket Water Straw PREPARATION OF BRICKS After selecting the clay, an area must be clear prior to start making bricks and a shed to protect the newly made against the rain as it can take a couple of days for them to dry. In the nearby, dig a hole of about 3 to 4 feet long, 2 to 3 feet wide and 2 to 3 feet deep as a mixing pit for the different ingredients. Then fill the hole with water and let it drain out as this will strengthen the wall of the hole for it not to crumble while mixing the clay soil. This will take at least a day to dry out.  Make mould of the bricks using timber. The traditional size is 4 by 10 by 14 inches and this is made with 2 by 4 studs nailed into a ladder like shape. MAKING ADOBE BRICKS Once the water in the pit has dry out, fill the pit halfway with the clay soil then add water gradually as mixing with the feet our shovel until the mix is stiff. Straw can be added to reinforce the mix but it is not necessary.Fill the mould using a shovel or hand thenlevel off the excess with the shovel or with a straight edge, makingsure there are no air pockets or gaps.  Let the bricks set and then gently remove the mould from them leaving the wet adobe bricks to dry for several days (at least three) before handling. Wash the mould and repeat the process in a different area. DRYING PROCESS Leave the adobe brick where they are while they dry in the sun for several days before turning them on the edge to completely dry out and harden and put under the shed so that the drying time can continue. When the edges turn white, they are ready to be moved, but not used. This process could take at least 3 weeks prior the brick is use. PART THREE THE FUTURE OF CLAY BRICK As the world population is growing especially in developing countries, there is a need of urbanisation to accommodate this populace meaning more bricks are needed to answer to this demand of infrastructure development. With the growing problem of energy price soaring, with the world running out of fossil fuel, with the reduction of deforestation which encourages the expansion of the desert, the clay brick industry is now facing an energy crisis and this crisis is affecting and will affect everyone. In the developed country, it is affecting the price of the accommodation and the house price while in the developing country it is leading to the impoverishment of many. This crisis resound as called for innovation by funding a new way of making new type of clay brick or improving the firing process by a new design of kiln aiming to reduce energy consumption by minimizing the energy required by the process as firing time and temperature in the kiln are the two key factors which contribute in the making of solid brick. In the developed country, electricity and fossil fuel are use as the main fuel source for brick firing as they are abundant. Founding other alternative to these sources of energy could be the way forward. But investing in nuclear power will raise an environmental issue of dealing with the nuclear waste; investing in the renewable energy will be a gamble in the way that, most of this technology are still in embryonic state and will require funding a good spot to install them and a big area to cover to be able to produce enough energy necessary to power this industries such investment will impair on the price of brick. It will mean also to divert energy which will be helpful to thousand household into industry. UNFIRED CLAY BRICK The way forward will be probably in reducing the energy consumption by designing better kiln and improving our knowledge of the minimum energy required by the process as unnecessary prolonged firing time and too high temperature will eventually consume more energy but minimum firing temperature and shortening firing time do not only reduce energy but also increase the productivity. In the developing country, this crisis reverberates as called for innovation, finding an alternative for curing clay brick as they are facing desertification. Curing is done, depending on the area, by fire wood, rice husk and maize cob or residue as main fuel sources for brick firing because they are abundant in developing country. Even though other agricultural waste such as saw dust and oil palm shell are used as substitute for wood, a new design of kiln is necessary to cope with the small size of fuel. If thinking in term of innovation in finding a new way of making clay brick, the new brick should be energy efficient in manufacturing process especial if cure through a kiln. Although the adobe clay brick may seem to be the answer but this brick however is not very strong or durable and tend to crack on drying. But one of the modern additions is to compensate this weakness by mixing soil clay with sand and stabilizing it with 4 to 8 % of cement or gypsum and then compress these materials in a given mould form, which results in strong and durable bricks, which do not crack. This is done with simple and yet innovative manually or engine-operated brick presses made from substantial steel sections with axle steel shaft with a top round shaft is case hardened carbon steel with a lid and with a bottom that moves up and down; the compression given by the machine compact the soil particles together to make dense regular shaped brick, usually 300x300x 130 mm in size and it is use  to produce interlocking soil clay bricks without burning. MANUFACTURING UNFIRED CLAY BRICKS This process uses the same type of clay use for the adobe brick. After the soil clay has been selected, it must be properly mix with Portland cement or gypsum then add water to the content so that the final product is a dry mixture containing about 15% water by weight. The dry mixture is poured in the mould of the press machine which is compress by pushing the press lever from one side to the other after closure of the top with a steel lid, with a force of about12 to 14 tons mould pressure. After the compression finish, the brick is eject from the machine and stack in the way to prevent water loss. Water is added daily so that the cement can be hydrated properly. The curing process will take about 28 days.   ADVANTAGES This Environmentally-sound building process is practical, inexpensive and  environmentallyHYPERLINK http://www.articlesfactory.com/articles/environment/soil-brick-making-machines-can-save-the-forests.html  HYPERLINK http://www.articlesfactory.com/articles/environment/soil-brick-making-machines-can-save-the-forests.htmlfriendly, as well as significant in cost savings and on-going green benefits, building with unfired soil clay bricks is one of the solution for the housing crisis because it has a lot of environmental benefits. Figure 2 The environment is protected in several ways: It lessens the ecological impact of building construction, thereby reducing deforestation and the need kiln. There is hence no need to burn the bricks, which makes this process a very low-energy requiring one. It saves money as the brick can be made On-site eliminating transportation, middlemen and breakage cost. On the other hand, unfired clay brick provide a sustainable and healthy alternative as replacement to conventional masonry materials. The structures made with soil bricks are as beautiful and durable as housing made from conventional bricks with the higher acoustical qualities that shut out exterior noise for less stressful living and reduce the need to heat or cool the interior. The soil brick is suitable especially for use in multi storey buildings, due to its durability and robustness. The bricks are already strong enough to be handled for storage when they leave the machine. Brick presses allow countryside people to build independently their own affordable bricks to self-build their houses and not have to rely on salesmen and production in towns, bad roads, transport problems and fluctuating prices. CONCLUSION The lack of fossil fuels the world will face shortly will drive the world in an economical crisis which we havent experience before driving up the price of accommodation. Though the idea of compress clay bricks from soil is far from new in the developing country, but for some unknown  reasons this technology doesnt seem to have made its brake through the developed world. There is a need to implement this new product of a low carbon footprint in the building industry.

Christianity and The Promotion of Slavery Essay examples -- Social Stu

One of the strongest roots of slavery and racism in the United States came from the Christian belief that blackness was linked with evil. This notion was used as moral justification to capture, enslave, punish, mutilate, and otherwise just inhumanely treat darker-skinned African people. Even before the colonies had been well established, It was widely accepted in Christianity that blackness and black skin were evil. One root cause behind the mating of blackness with evil was the bubonic plague in Europe in the 14th century. The bubonic plague was a deadly epidemic which killed between thirty and fifty percent of Europe's population (close to seventy-five million people). The bubonic plague, because it wiped out at least a third of Europe's population, had very deep and lasting impacts on the course of history. When infected victims were very close to death, their skin would blacken as a result of hemorrhages, or blood clots. At this point, there was no hope for the victim . Hence the bubonic plague came to be known as the black death. It is also important to note that these were the middle ages, and people in this period suffered through frequent outbreaks of famine, disease, war, and generally economic hard times. Society was also not very progressive, and people lived in constant fear of God. The churches played a very large role in that 'dark' society and in time, the bubonic plague left an i ndelible mark on Christianity: black was evil and signified hunger, suffering, disease, hard times, and death. The second major contributor to the notion that blackness was evil had to do with the constant strife between western European Christian nations and the people of the middle east, typically Muslim in faith: "One of the defini... ... free...and baptism doth not bestow freedom on him, nor make any alteration in his temporal condition...we are also of the opinion, the master may legally compel him to return to the plantation ". Later revised versions of this philosophy which led to the fugitive slave clause in the constitution of the United States left out part about baptism, but it is important to note that their origins mentioned baptism. This is a prime instance of religious beliefs working their way into the law books regarding slavery. Works Cited "Black Death." Middle-ages.org.uk. Web. 18 May 2012. . Hood, Robert E.

Arthur Miller’s †The Crucible Essay

In 1953 Arthur Miller wrote a play entitled The Crucible, by writing this he aimed to challenge the assumptions of US society and led people to question each others responsibilities. In the 1950’s senator Joe McCarthy started to exploit the US fears of communism and organised a witch hunt. Miller would have seen this as similar to the Holocaust in the sense that people were being wrongly accused of being witches when they were not. Arthur was a Jew and so would have had sympathy with these people and this in my eyes was one of the key factors in the writing of this play. During the 17th century there was an outbreak in the belief of witchcraft in Europe. This led to mass immigration from Europe to America; the immigrants were Puritans and so set up their own strict Christian communities. This is how Salem, Massachusetts came into being. Miller’s characters convey my point through their change of personality from Act I through to Act IV. There are different types of change throughout the play such as change in character, beliefs and loyalty and these all occur at some point in the play to different characters. Proctor, a farmer, goes from a local, well respected man to a man accused of being in contact with the Devil. Abigail transforms from sweet and beautiful to malicious and evil. Hale on the other hand is bought into the play as a witchcraft ‘expert’, he ends up struggling with this particular case and so changes into a frail, old and weak man. Putnam is much like Proctor and his story throughout the play is much the same and ultimately ends in death. The first time Putnam is mentioned he is said to be ‘vindictive’, meaning he is sly and malicious. But there is a reason for this nature of his; Miller does say that Thomas Putnam is a man ‘with many grievances’. This quote alone says that his vindictive nature comes after a certain event in his life, this being that James Bailey (his son in law) had been turned down as minister of Salem. But this changes completely as the accusations of witchcraft come out from the woodwork, instead of being scarred by this grievance he turns to his controlling self. During Act I the Putnam family cry witchcraft on a certain Rebecca Nurse; this is all Thomas Putnam’s alter ego. The Nurses were the ones who ultimately prevented James Bailey from taking office in Salem and for Putnam, blackening the Nurse name would surely open the gateway for Bailey to become minister of Salem. So, at the start of the play Putnam is portrayed as the accuser, and rightly so. But as we go on through the play we see Putnam’s character change somewhat rapidly from the accuser to the accused. This is proven correct when in Act III Danforth says, ‘Mr Putnam, I have here an accusation by Mr Corey against you.’ This accusation alone shows how Putnam’s personality has changed from one extreme to the other; he has gone from accuser to the accused. This outlook on Thomas Putnam goes someway to describing how the whole ordeal in Salem has changed everyone and is bigger now than ever before. This shocks the audience as it shows that this whole ordeal in Salem is changing even the most respectable of men. The next character we see is Reverend Hale; he is brought in by Parris as a master of the supernatural arts, witchcraft. We are first introduced to Hale as, ‘Mr Hale is nearing forty, a tight-skinned, eager-eyed intellectual’. This makes the audience think straight away that Hale is a well respected and well educated individual who is very contempt with his job, to the extent he actually enjoys it. Miller described Hale as someone who, ‘†¦felt the pride†¦Ã¢â‚¬â„¢. This shows Hale took pride in the fact he was sought after and good at his job, and a specialist in such areas. So, from how Miller describes Hale we see his willingness to be involved with this court and eager to show off his ability, as this improves his self esteem.. So it would be easy to assume that Hale would be a figurehead for the further Acts in the play, this is true to some extent, until Act III where Hale ultimately loses his head; he realises how much this case has affected Salem and its citizens, ‘I denounce these proceedings, I quit this court’. This quote itself lets the audience know how much the situation in Salem has blown up into something that never should have been. How it has all spurred from one accusation to a further ten, then at the end, over one hundred. It shows the audience how the situation has affected so many people and that Hale is the first to realise this. He, as a result, quits the court, this giving evidence to the statement that Hale’s personality has completely changed. At first he wants to be involved (the hero) and take pride in his work. But now, n Act III he gets as far away from the case as possible, it shows how the situation is changing people, and more so how it has changed Reverend Hale. Hale is now portrayed as a weak, deflated individual, lacking in personality. He goes from strong to frail and deflated. The audience watching this would feel confused at seeing this radical change in this holy moral figure.  Possibly the most important ambassador for change in The Crucible is John Proctor. We are first introduced to him during Act I, Miller describes John Proctor as, ‘†¦a farmer in his middle thirties. He need not have been a partisan of any faction in the town’

Ict in School Education

Information and Communication Technology for Education in India and South Asia Essay II ICT in School Education (Primary and Secondary) ICT in School Education (Primary and Secondary) 2010 Executive Summary The essay on use of ICTs in school education provides a study of trends and dominant features of the use of ICTs for school education as profiled in different initiatives captured in the country reports. The essay highlights the spectrum of experiences from high-end technology solutions to low-end TV/radio-based initiatives that have been successful in different countries at the K12 level.The paper also examines the key issues and challenges in the effective implementation of ICTs in school education and provides suggestions to address these challenges and aid the implementation of ICTs in school education. An observation of international trends in application of ICTs in schools indicates that it is directly related to the development of schools and the teaching and learning envir onment. It is observed that new and emerging technologies are being integrated with the older technologies to make ICT applications in education more effective.Educators are also showing an increasing tendency to use mobile technology to enable access to education. There is a great deal of effort being expended around the world on the development of systems that will standardize the development of resources, catalog them, and store them. These include learning objects, which are digital Web-based resources created to support learning and can function as discrete entities or be linked in order to relate to explicit concepts or learning outcomes.Repositories are libraries where these digital resources are stored and provide teachers, students, and parents with information that is structured and organized to facilitate the finding and use of learning materials regardless of their source location. ICT in School Education (Primary and Secondary) The United Nations’ Millennium Deve lopment Goals (MDGs) two and three are about achieving universal primary education and promoting gender equality, respectively.The MDGs in education are defined in terms of participation and completion of primary education by all children and the elimination of gender discrimination in education. Despite the continued efforts of the various Governments on universalizing the primary and elementary education, through a wide range of programmes and schemes, access to quality education continues to be an obstacle in the achievement of the education goals. For instance, in India, during 2004 – 05, while the Gross Enrolment Ratio for children enrolling in classes I to VIII was 97 percent, the Drop-out Rate for the same classes was as high as 46 percent.The situation is more worrying at the secondary education level (classes IX and X), where the enrollment is recorded at 53 percent and the Drop-out Rate is as high as 60 percent1. Efforts so far have addressed to a considerable degre e, the concerns of equity as well as that of regional parity, however concerns of quality have not received adequate attention. Recognizing this, the Government of India’s flagship education programme at the primary level – the Sarva Shiksha Abhiyan (SSA) – has streamlined its focus on ‘quality’. The situation is similar across the South AsiaSelected Educational Statistics 2006 – 07; Government of India, Ministry of Human Resource Development, New Delhi 1 2 ICT in School Education (Primary and Secondary) 2010 region. With the target timelines for universalizing of primary and secondary education nearing, there is a sense of urgency in accomplishing the goals set therein. As is being increasingly articulated, if after spending large sums of money on programmes and schemes, countries have not become fully literate, it is time that innovative and cost effective methods be put in lace to address the problem of education in these countries2. While this is a larger problem and points to the need for reform in the educational systems of these countries at various levels – pedagogical, curricular, as well as institutional, the emergence of various Information and Communication Technologies (ICTs) and their increasing acceptance and adoption by society provide unique opportunities and could potentially promote education on a large scale.While there is no conclusive research to prove that student achievement is higher when using ICTs in the education space, either in the developed or developing countries, there is a general consensus among practitioners and academics that integration of ICTs in education has a positive impact on the learning environment.It is understood that in diverse socio-economic and cultural contexts ICTs can be successfully employed to reach out to a greater number of students, including those to whom education was previously not easily accessible, and help in promoting learning, along with exposing students to the technical skills required for many occupations. ICTs act as and provide students and teachers with new tools that enable improved learning and teaching. Geographical distance no longer becomes an insurmountable obstacle to obtaining an education.It is no longer necessary for teachers and students to be physically in proximity, due to innovations of technologies such as teleconferencing and distance learning, which allow for synchronous learning. 3 ICTs in schools provide an opportunity to teachers to transform their practices by providing them with improved educational content and more effective teaching and learning methods. ICTs improve the learning process through the provision of more interactive educational materials that increase learner motivation and facilitate the easy acquisition of basic skills.The use of various multimedia devices such as television, videos, and computer applications offers more challenging and engaging learning environment for students o f all ages. 4 A study conducted by the International Institute for Communication and Development (IICD) indicated that 80 percent of its participants felt more aware and empowered by their exposure to ICT in education, and 60 percent stated that the process of teaching as well as learning were directly and positively affected by the use of ICT. Twenty-first century teaching learning skills underscore the need to shift from the traditional teacher-centered pedagogy to more learner-centered methods.

ICT in School Education in the Developing World In the developing world, ICTs are used largely to increase access to and improve the relevance and quality of education. ICTs have demonstrated potential to increase the options, access, participation, and achievement for all students. The unprecedented speed and general availability of diverse and relevant information due to ICT, extends educational opportunities to the marginalized and vulnerable groups, among the other disadvantaged.ICTs in the developing world have the potential to enhance the education experience for children who: ? ? ? ? ? live in rural and remote-rural locations have special learning needs have physical disabilities constraining their access to schools have dropped out and/or have kept themselves out of school for various reasons. aim for excellence and fail to get satisfied in the current system Teachers and learners in the developing world are no longer solely dependent on physical media such as printed textbooks which are often times outdated.With today’s technology, one even has the ability to access experts, professionals, and leaders in their fields of interest, around the world at any given time. 7 In India, various ICTs have been employed over the years to promote primary and secondary education. These include radio, satellite based, one-way and interactive television, and the Internet. However, there have been enormous geographic and demographic disparities in their use.Some states in the country currently have an enabling environment in place that allows for a greater use 6 7 Haddad and Jurich, â€Å"ICT for Education: Potential and Potency† Ibid 4 ICT in School Education (Primary and Secondary) 2010 of ICTs for education, whereas other states lack such an environment making the use of ICTs for this purpose very sporadic. 8 It is a lso important to keep in mind that ICTs in education are a potential double-edged sword— while ICTs offer educators, tools to extend education to hitherto naccessible geographic regions, and to deprived children and empower teachers and students through information, there is also the danger that such technologies may further widen the gap between the educational haves and havenots. However, technology is only a tool and the success of ICTs in enhancing the delivery of quality education to the needy, without widening the gap, will depend largely on policy level interventions that are directed toward how ICTs must be deployed in school education.The Governments in each of the countries in the South Asia region are now keen and committed on exploring the uses of ICTs for school education. Therefore, Government policies lately reflect their realization of the importance of integrating ICT use and the promotion of quality education enabled through ICTs. The creation of educational networks offer substantial economies of scale and scope, when attempting to improve the quality of education and seek to standardize quality across the system.Hence, Governments are investing in infrastructure facilities that link schools/educational institutions and resource centers. However, despite administrators and experts alike recognizing the potential of ICT in improving access to quality education, the utilization of ICTs in school education in the South Asian countries is still not at a very advanced stage. The following table classifies countries in the Asia Pacific region based on their appreciation of ICTs and the availability of ICTs. It shows that while appreciation of ICTs is high in the South Asia region, their actual availability for utilization is low.Countries Appreciation of Availability of Technology Technology Afghanistan Low Low Australia High High Bangladesh High Low Bhutan High Low Cambodia High Low China High Low Central Asia (Kazakhstan, Kyrgyzstan, High No available data Tajikistan, Turkmenistan, Uzbekistan) Democratic People’s Republic of High No available data Korea India High Low Indonesia High Low Iran High No available data ‘Promoting the Use of Information and Communication Technologies for Primary and Secondary Education: The Case of the States of Chhattisgarh, Jharkhand and Karnataka in India’ Discussion Paper by Amitabh Dabla, Educational Development Centre, Bangalore India. 8 5 ICT in School Education (Primary and Secondary) Countries Japan MalaysiaMaldives Mongolia Myanmar Nepal New Zealand Pacific Islands Countries Lao PDR Republic of Korea Sri Lanka Thailand Vietnam Appreciation Technology High High High High High High High High High High High High High of Availability Technology High High Low Low Low Low High Low Low High Low Low Low 2010 of Source: Strategy Framework for Promoting ICT Literacy in the Asia–Pacific Region, UNESCO Bangkok Communication and Information Unit, 2008 http://www2. unescobkk. org/elib/publications/188/promotingICT_literacy. pdf South Asia is yet to harness the potential of ICTs in creating, constructing, capturing, managing, and sharing information and knowledge. India is rated high on appreciation because it has gone beyond policies that merely recognize the strategic role of ICT for growth and development and is already institutionalizing concrete measures that support ICT initiatives.However, it has been rated low on availability of technology due to data reporting that access to computers is â€Å"limited,† the cost of Internet connections is relatively high, ISPs are described as â€Å"limited,† and the ratio of number of computers per student stated as â€Å"insufficient. †9 These observations point to the need to frame appropriate policies, build adequate infrastructure, and set aside adequate funds in order to support the deployment of ICTs in furthering the education levels of the country. Although ICTs do offer m any beneficial opportunities for education, they are no substitute for formal schooling. The role of technology is to support school education and not replace it, though the technology may play an appreciable part in meeting the needs of children who cannot go to a conventional school.Access to ICTs ensures enhancement of traditional or formal education systems, enabling them to adapt to the different learning and teaching needs of the societies. ICTs in school education initiatives that focus on the following areas are most likely to successfully contribute to meeting the Millennium Development Goals10: ? Increasing access through distance learning Strategy Framework for Promoting ICT Literacy in the Asia Pacific Region, Elena E Pernia, UNESCO Bangkok Communication and Information Unit, Asia and Pacific Regional Bureau for Education, Thailand 2008. 10 The World Bank. 9 6 ICT in School Education (Primary and Secondary) 2010ICTs can provide new and innovative means to bring education al opportunities to greater numbers of children of all ages, especially those who have historically been excluded, such as populations in rural and remote-rural areas, girl children facing social barriers, and children with disabilities and other compulsions. In almost all the developing countries of South Asia, distance learning has been an important component of the education policy of these nations. It is probably in this domain that traditional ICTs like radio, television, and audio cassettes were first deployed in the education space. In India, distance learning offered by institutions like National Institute of Open Learning (NIOS) and Indira Gandhi National Open University have used a combination of print and audio-visual material as well as traditional face-to-face interactions to deliver their content. Enabling a knowledge network for students With knowledge as the crucial input for productive processes within today’s economy, the efficiency by which knowledge is acq uired and applied determines economic success. Effective use of ICTs can contribute to the timely transmission of information and knowledge, thereby helping education systems meet this challenge. ? Training Teachers Large numbers of school teachers will be needed to meet the MDGs for education. The use of ICTs can help in training teachers to accomplish the targeted tasks on a mission mode. Moreover, ICTs provide opportunities to complement on the job training and continuing education for teachers in a more convenient and flexible manner. The use of ICTs for teacher training has been recognized by the governments of most South Asian countries and eacher training programmes like Intel Teach across India, Pakistan, and Sri Lanka; Microsoft Shiksha in India; and several other initiatives in Nepal and Bhutan are focused on using ICTs for training teachers. This includes training in applying ICTs in their teaching practices as well as using ICTs as a mode of delivery for these trainings. ? Broadening the availability of quality education materials Development of relevant, good quality content is perhaps the biggest challenge and opportunity in the educational technology space. While infrastructure, capacity building, monitoring, and evaluation are critical support structures without quality content, the learning experience of students will not be significantly improved by the mere presence of ICT.To that end content development is being focused on in many of the focus countries in our study. In India, several initiatives are ongoing for creating digital repositories and learning objects; the Sakshat Portal of Government of India, initiatives like National Program of Technology Enhanced Learning (NPTEL), the Multimedia Educational Resource for Learning & Online Teaching (MERLOT) seek to create quality digital content for different levels of education. 7 ICT in School Education (Primary and Secondary) ? 2010 Enhancing the efficiency and effectiveness of educational a dministration and policy New innovative technologies can help schools’ improve the quality of administrative activities and processes.The Government of Afghanistan’s articulation of the policy for ICT in education focuses on the need to provide access to ICT for all Ministry of Education administrative staffs, teachers, and students. The policy further envisages that through the use of information management systems, ICT will be extensively used to automate and mechanize work such as human resource management, financial management, monitoring and evaluation, the processing of student and teacher records, communication between government and schools, lesson planning, assessment and testing, financial management, and the maintenance of inventories. The Ministry of Education has developed GIS-based spatial data with detailed maps for better management of the education system in the country.More than 35 maps have been produced showing the location of schools all over Afgha nistan, including the number of students and teachers by province. The Government of Delhi, in India, has been a pioneer in using ICTs for better administration of the education system. The Department of Education, Government of Delhi, with 40,000 employees, 928 schools, and more than 120,000 students under its administrative jurisdiction has developed a comprehensive and functionally effective Web-based and GIS-based Management Information System (MIS). All the schools, zonal offices, district offices, regional offices, and various branches at the headquarters can share information using the Web-enabled software.Information for all stakeholders—students, teachers, and administrators—is available online through the Directorate’s Web site (edudel. gov. in); this includes information on admissions, mark sheets, teacher attendance, transfers, pay slips, and so on. International Trends in ICT in School Education An observation of international trends in application of ICTs in schools indicates that it is directly related to the development of schools and the teaching and learning environment. For instance, changes to pedagogical practices in classrooms require that teachers should have access to infrastructure and are given the opportunity to develop the expertise to use the machines and software tools.The trends also indicate policy-makers, administrators, and teachers are using a variety of tools and strategies to improve access to learning opportunities, improve the teaching and learning experience for teachers and students, and make effective use of limited resources. This section presents a select few international experiences that have been observed in ICT applications in primary and secondary education across the globe. 11 Integrating New Technologies with Existing Technologies in Use A discussion on global trends in ICTs and Education in 2010 can also be found at the Education Technology Debate Forum of the World Bank http://edutechdeb ate. org/2010-ict4e-trends/10-global-trends-in-ict-andeducation-for-2010-and-beyond/. It highlights trends like Mobile Learning, Cloud Computing, Gaming, Ubiquitous and Personalized Learning. 11 8ICT in School Education (Primary and Secondary) 2010 Older technologies such as print, radio, and television are more common in most part of the world, unlike the recent technologies such as Internet, e-mail, and wireless communications. This is largely due to the state of infrastructure development that had not allowed the adoption of newer technologies as extensive as the older technologies. In recent times, however, it has been noticed that these newer technologies are gaining prominence and are being integrated with the older technologies to make ICT applications in education more effective. Radio Sagarmatha in Nepal is one of the first community radios in South Asia.It is a radio-browse model wherein Internet is broadcast over the radio. It discusses public issues, conducts training fo r public radio journalism, and provides a venue for local ideas and culture. In 2000, the station added a weekly 25-minute Internet radio programme featuring local and international ICT-related news, and ICT glossary, radio web browsing, and interviews with relevant ICT resource persons. This program has been successful among the rural areas of Nepal. Increased Use of Mobile Technology In the developing countries of South Asia given the almost ubiquitous presence of mobile phones in some geographies, there is an increasing interest in the opportunities offered by this technology.Several initiatives using mobile phones for English language learning, for facilitating educational administration tasks, and other support informational and educational services are being widely offered. In India, Bharat Sanchar Nigam Limited (BSNL), one of the largest telecom service providers with the widest reach in the country has launched â€Å"Learn English,† a spoken English mobile learning pr ogram. The program aims to teach spoken English through common everyday stories and situations that are familiar to most people. It is currently available in nine regional languages for two levels, namely basic and advanced. The service can be subscribed to at a nominal cost of Rs. 0 per month and a call browsing charge of 30 paise per minute. Other service providers have also entered the arena. IL&FS Education & Technology Services Limited (IL&FS Education) in collaboration with Tata Indicom have launched an â€Å"English Seekho† Program, which uses the mobile phone to teach English through simple 5 minute lessons that can be accessed at the learner’s convenience. Another common usage of mobile phones is also found in support services for education, such as providing alerts and retrieving and sending EMIS reports. The Virtual University in Pakistan makes use of SMS to provide updates to students, schedule appointments, and so on.However, as articulated by educationist s and experts, the small screen size, limitations on the amount of data exchanged, and so on are problems that limit the usage of mobile phones (the models most commonly available) in actual content delivery in education. 12 Content Development through Learning Objects and Repositories 12 For a debate on the use of Mobile Phones vs PCs in Education refer to Edutech Debate at http://edutechdebate. org/mobile-phones-and-computers/ 9 ICT in School Education (Primary and Secondary) 2010 Learning technologies have been evolving over the last many years, starting from early mainframebased programmed learning systems, microcomputer software packages, bulletin boards, CBT systems, authoring systems, and more recently after the Internet explosion, Web-based systems and Learning Management Systems.Development of content has largely been done on an individual basis, resulting in a scenario where the content software is not compatible with the latest technology. Moreover, there is no establishe d system for cataloging and classifying virtual learning materials, leading to many excellent online learning materials remaining underutilized. This scenario calls for the need for a standardized system for cataloging, storing, and retrieving content in ways that enable users to access and organize resources for their particular purposes as well as sharing it institutionally, nationally, and internationally. There is a great deal of effort being expended around the world on the development of such systems—ones that will standardize the development of resources, catalog them (metadata) and store them.Learning objects are digital assets that can be as diverse as a chapter in a book, a piece of text, a video or audio clip, or visuals on an overhead transparency or PowerPoint slide, and can be used in a variety of teaching settings, by course designers, managers, trainers, content writers, and learners. 13 Learning objects can be identified, tracked, referenced, used, and reused for a variety of learning purposes. They are developed to function as discrete entities or to be linked in order to relate to explicit concepts or learning outcomes. Content requirements are determined through communication with educators across the target audience and then the learning object is developed by independent contractors.Learning objects may be self-contained, reusable, and capable of being aggregated. Repositories may be described as libraries where learning object databases are stored and provide teachers, students, and parents with information that is structured and organized to facilitate the finding and use of learning materials regardless of their source location. Most repositories contain a Web-based user interface, a search mechanism, and a means of retrieving a learning object. While the initial leadership for learning object repositories has tended to come from the university sector, the interest and activity in the school sector is increasing rapidly. An Over view of Developments and Trends in the Application of Information and Communication Technologies in Education’; Glen M Farrell, Commonwealth of Learning; UNESCO Meta-survey on the Use of Technologies in Education, October 2003. 13 10 ICT in School Education (Primary and Secondary) 2010 Open Learning Exchange, Nepal: E Pustakalaya and E Paath OLE Nepal is engaged in creating content at two levels. The E Paath consists of interactive learning modules, mapped to the topics in the curriculum as prescribed by the Curriculum Development Centre (CDC) of Nepal. Subject matter experts work closely with the OLE Nepal developers to create these interactive learning activities. This easy to use software, rich in multimedia elements including text, audio, video, and animations is then used by teachers and students to understand concepts as prescribed in the curriculum.The content contains lessons, exercises, as well as assessment tools to enable teachers to effectively teach and evaluate students. E-Pustakalaya is an electronic library which is a repository of reference material for the students, consisting of full text documents, images audio, video clips and software that are relevant for students. E Pustakalaya deploys a simple child friendly user interface that allows children to navigate, search, and link different documents including reference materials, courserelated content, magazine, and newspaper content. Students can download the content as well as read it online. The repository is also accessible on the Internet to other users at http://www. pustakalaya. org.Content creation in the E Pustakalaya is an ongoing activity and OLE Nepal has collaborated with several national and international organizations to source materials, these include Room to Read, Rato Bangala Foundation, Madan Puraskar Library, Save the Children, World Education, ELearning for Kids and Azim Premji Foundation. OLE Nepal continues to work with other organizations to supplement this data base. (www. olenepal. org/) eGyankosh, Indira Gandhi National Open University (IGNOU), India eGyanKosh, developed by IGNOU and launched in 2008, is a National Digital Repository created to store, index, preserve, distribute and share the digital learning resources developed by Open and Distance Learning Institutions in India. The repository contains all course material of IGNOU in print and video format and allows users to download this material free of cost once they have registered themselves. www. egyankosh. ac. in/) As learning repositories are developed, there emerged a need for international standards for these repositories, with the aim of achieving interoperability among various learning repositories. The development of easily accessible and sharable learning repositories is perhaps the most significant trend of all because of the potential it holds for reducing one of the largest single costs in the use of ICT in education—the cost of developing content. This develop ment offers not only the economy and flexibility that comes with reusability but also allows content to be developed independently from the form of its delivery.It offers benefits across the spectrum of learning venues, from the remote learner in some form of distance education, to the teacher and learners face-to-face in a classroom. 11 ICT in School Education (Primary and Secondary) 2010 Teachers and Online Learning Activities ICT is an important source, which teachers may use to keep themselves abreast of emerging issues, share knowledge, and reach out to students. Several portals are being developed where teachers can network and share information including best practices. In India, the Sakshat portal developed by the Government of India provides teachers an opportunity to connect with each other and share experiences.The Teachers of India, an online portal developed by the Azim Premji Foundation and the National Knowledge Commission, was created with the objective of providing a forum for teachers to freely interact with each other across languages, facilitate the sharing of insights and best practices of teachers across the country and provide access to resources, information, and new experiments in education from all over the world in all Indian languages. Key Issues and Concerns There are many challenges in implementing ICTs effectively in existing schools. Policy-makers need to give ICTs adequate priority and attention so as to reap the benefits of deploying ICTs in school education.Students from rural locations or impoverished communities often tend to slip under the radar so that they do not have even basic access to ICT. Given that a number of schools still do not even have appropriate classrooms, computers, telecommunication facilities and Internet services, ICT continues to be a distant dream. The existing shortage of quality teachers further compounds the problem. In developing countries, budgetary allocations for deploying ICTs in school educat ion are typically limited, and given the high initial costs of setting up ICT systems, the cost factor works as a further deterrent. Shifting the existing focus from traditional educational models to an ICT-based education system is bound to be met with constraints and roadblocks.Some key issues and concerns that need to be addressed in order to create an ICT friendly environment in schools, especially in countries in the South Asian region, are identified later. Availability of Infrastructure to Support ICT A country’s educational technology infrastructure sits on top of the national telecommunications and information technology infrastructure. Availability of adequate infrastructure to support the deployment of ICTs in schools is a tremendous challenge that schools in the region currently face. Apart from the high initial cost of purchasing and setting up the requisite infrastructure, the maintenance and upgrade costs, as well as the cost and effort of supporting such infra structure are also roadblocks to the successful usage of ICTs in schools, especially in poor and remote areas.Before any ICT-based programme is launched, policy-makers and planners must carefully consider the following: ? In the first place, a basic requirement is whether appropriate rooms or buildings available to house the technology? In countries where there are many old school buildings, extensive retrofitting to ensure proper electrical wiring, heating/cooling and ventilation, and safety and security would be needed. 12 ICT in School Education (Primary and Secondary) ? 2010 ? ? Another basic requirement is the availability of electricity and telephony. In countries within this South Asian region, large areas are still without a reliable supply of electricity and the nearest telephones are miles away.Power situation in rural and remote-rural areas even in some advanced countries in this region is undependable, and this affects the functioning of any ICT initiative. Power cuts wi th different power cut schedules each week play havoc with the timetables. Power outages and fluctuations add to the high maintenance costs of computer hardware. Policy-makers should also look at the ubiquity of different types of ICT in the country in general, and in the educational system (at all levels) in particular. For instance, a basic requirement for computer-based or online learning is access to computers in schools, communities, and households, as well as affordable Internet service. Insufficient access to computers is one of the main obstacles to the spread of ICT usage in school education.This is more so in the case of rural areas where the school is often the only access point for computers. Moreover, system software is expensive and prone to upgrades and requires resources put aside for new versions and upgrades. Operating System (OS) itself adds to the cost burden of the hardware. Although this will require massive investments in the infrastructure, it is nevertheless essential in order to guarantee equal access and to overcome the digital divide. 14 Strong, sustainable partnerships between the Government, private sector and civil society must be built to offset costs and mitigate the complexities of the integration of ICT in education systems (refer Annexure II for details on Public-Private Partnerships [PPPs]).Availability of Funds to Implement ICTs Given the current budgetary and resource constraints of various Governments, a widespread investment in ICTs in education is probably not possible in most developing countries. It is, therefore, critically important to better understand the cost-benefit equation of the wide range of ICT options and uses in order to effectively target-spend the scarce resources. Economies of scale are achievable in distance education, although such Programmes typically require large up-front investments. Some of these costs may be shifted from the public sector to the individual users, but this in itself raises sign ificant equity and access issues.Capacity Building of Teachers In most of schools in the subcontinent, the teachers are overloaded, less motivated and inadequately trained, and often deal with inconvenient working conditions. The use of ICTs in the classroom or in distance education does not diminish the role of the teacher; neither does it automatically change teaching practices. In such an atmosphere, building the capacity of teachers so that they are equipped to deal with using ICTs in classrooms is a challenge. Resistance to Change International Institute for Communication and Development, ICTs for Education: Impact and Lessons Learned from IICD-Supported Activities. 14 13 ICT in School Education (Primary and Secondary) 2010Resistance is commonly witnessed while attempting to introduce ICTs into schools, very often from the teachers themselves, since they may be of the opinion that they shall become redundant once technology comes in or due to their perception that it is too lat e for them to adapt to a new environment. Educators themselves may be skeptical about the effectiveness of using ICTs in school education. Lack of Awareness There is a general lack of awareness about the utility of ICTs in education, as well as about the ICTs at our disposal and how they can be accessed and utilized economically and effectively. This lack of awareness and knowledge about ICTs and their use in education, even on the part of policy makers, administrators and educators, makes it particularly difficult to deploy ICTs in the field of school education.Another critical issue with the usage of ICT in schools is the implementation of new technologies without having analyzed their appropriateness, applicability and impact on various environments and contexts. In most countries, particularly the least developed ones, they must learn from the experiences of others, but must also use technology to respond to their own needs and not just follow trends. 15 Internet Usage While the Internet contains tremendous potential for education, as described in the sections earlier, it also has its own pitfalls. For one, providing all the students with Internet access is a very expensive proposition for most Government schools. This is more so in the case of rural centers and remote areas, where Internet connections are bound to be erratic, if available at all.A different challenge altogether when it comes to Internet usage is the effort involved in monitoring the students usage of the Internet to ensure that they do not visit educationally irrelevant and socially undesirable sites, thus detracting from the intended objective. Language Barriers English is the dominant language of the Internet. An estimated 80 percent of online content is in English. A large proportion of the educational software produced in the world market is in English. For developing countries in the South Asian region where English language proficiency is not high, especially outside metropolitan ar eas, this represents a serious barrier to maximizing the educational benefits of the World Wide Web.Monitoring and evaluation Many of the issues and challenges associated with ICTs in education initiatives are known by policymakers, donor staff, and educators. However, data on the nature and complexity of these issues remains limited because of the lack of good monitoring and evaluation tools and processes. Where evaluation data is available much of the work is seen to suffer from important biases. Another Patti Swarts, â€Å"Main Issues, Possible Solutions and Opportunities for ICTs,† Global e-Schools and Community Initiatives, http://www. gesci. org 15 14 ICT in School Education (Primary and Secondary) 2010 problem in this area is the lack of a common set of indicators for ICTs in education.And, where data has been collected, it is often quantitative data related to infrastructure (number of computers, for example) rather than data that can help policy-makers gauge the impa ct of ICT interventions on student learning. 16 If ICTs are to become effective and integral tools in education, and if accountability is to be demonstrated to donors and stakeholders, monitoring and evaluation must be a priority area of focus (refer Annexure I for details on Monitoring & Evaluation). Key Learnings Although there is great opportunity for improvement in school education at many levels through the use of ICTs, the road to achieving it is not easy. It will take continued commitment from all stakeholders involved to make any kind of substantial and sustainable change.The following broadbased suggestions may act as a basis for building a long-term roadmap to bringing ICTs to schools, and students at large in the South Asia region. A key to succeed in this endeavor is to adopt a comprehensive, end-to-end, systematic approach, with a phased and learn-as-you-go strategy for implementation, that can be adjusted to adapt to the specific needs and a changing environment. Gover nment Support Government cooperation is necessary for ICT programmes to have substantial impact and be sustainable. In the attempt to reevaluate the education delivery system and curriculum of countries to include ICT, Governments have to consider the social context in which they are implementing this new phenomenon.The realities of individual countries and the disparities within and across their geographies, including their limitations say, the language barrier, should be considered and the availability of ICT should be made according to the needs and desires of the countries in order to facilitate appropriate learning and local ownership of knowledge. 17 As discussed in the essay on policy coherence, governments need to adopt a coherent national policy framework, an effective ICT for education ecosystem, not just within the education field but also encompassing other complementing and enabling domains, which could ensure a child’s overall development and the Country’ s larger objectives. Government policies must demonstrate political will and champion the integration of ICT purposes and be in line with national development goals and frameworks.In countries where implementation capacity is weak and misuse of resources can be a major problem, ICT can further enable the country to enhance its capacity building efforts and reduce the opportunity for corruption. 18 16 Trucano, Michael. 2005.

Ministries of Education need to reconsider how they institutionalize positions of responsibility for ICT. The ICT unit’s roles relate directly to improvement of teaching and learning using ICT, and the mix of skills required differs substantially from that of a traditional IT unit, providing infrastructural systems support. Therefore, appropriate considerations have to be taken to establish the right kind of institutions and positions to take the mission forward. In the longer term, the active participation of the Government is essential to ensure the sector-wide introduction of ICT4E.Government involvement is critical to source additional investments in the ICT infrastructure, to int egrate ICT in the curriculum, and to facilitate the widespread diffusion of materials. 19 Creating Community-Based ICT Facilities In 1999, the Bangladesh Rural Advancement Committee (BRAC) undertook an initiative to improve rural communities’ access to ICT facilities. This involved selecting 800 Gonokendros (multipurpose learning centers) and equipping them with computers so that rural communities become familiar with usage of ICT and have access to a wide range of reading materials and resources, educational and non-educational. The concept of community-based ICT facilities may be expanded at the school level to increase school students’ access to ICT-based materials. For example, one ICT centre may be created for every ive schools in the village/block, and this centre may be equipped with computers, television, radio, or other technologies. A timetable may be allocated so that each school has access to the ICT centre for one day of the week. Within each school again, different classes may be allocated different periods for accessing the ICT centre. The challenges with implementing such a scheme, is that the distance of the centre from the various schools that warrant the need for firming up the mode of students’ mobility and the frequency of such mobility to access the ICT facility and others. Moreover, the cost of renting or buying land and a building for setting up the ICT centre is another deterrent.However, this concept of school communities using common ICT facilities is a feasible way in which to introduce students from rural communities to ICTs. Prioritizing and Planning Access to Remote Areas Special consideration should be given to ICT connectivity and accessibility for educational purposes.

Regional networks of collaboration among countries where language and cultural context are similar could serve as a platform to promote educational quality and equality in an effort to bridge the digital divide. Greater exchange and collaboration in the production and management of educational resources would lower expenses in the development of materials as well as increase the amount of educational content available to teachers and students across the region. 0 Adopting ICTs Suited to the Context Given that Internet access is a problem for most schools, especially in rural areas, educators and administrators needs to consider the p ossibility of establishing Local Area Networks (LANs) in schools. Content could be hosted on school LANs, instead of trying to make them available on the Internet. A digital library on a server on the LAN would be a valuable asset, as it can store all types of digital content. Interactive multimedia material can also be hosted on the LAN at a much lower cost than on the Internet. This also has the added advantage of enabling students to access Programmes at their convenience, instead of having to adhere to a scheduled telecast.Given that India has invested significantly in educational television and already has a commendable satellite television infrastructure, schools should focus on leveraging this technology. Some Indian educational channels are planning to switch to DTH soon, and it is very practical for them to do this. Due to the rapid fall in the cost of servers and storage, it is possible to record thousands of hours of TV programmes in digital form onto a server and make it available on demand from every PC on the LAN. 21 Focus on Capacity Building The use of ICTs in education calls for a fundamental shift in the way content is designed and delivered, as well as for teamwork and collaborative practices.New technologies cannot be imposed without enabling teachers and learners to understand these fundamental shifts. Ongoing training is necessary for the trainers in institutions and organizations who are engaged in the design of curriculum, teaching materials, and delivery of ICT-enabled education. At the same time, middle-level managers, both in the public service and the NGO sector, need to understand the pedagogy of learning through ICT and the management models that are required. Given that teachers themselves are not comfortable using ICTs for teaching purposes, it is critical that there is a focus on capacity building of teachers so that they are equipped adequately to use ICTs in the classrooms.A locally-accessible instructor/trainer may be hired to provide training to the teachers on the usage of computers and Internet, and other ICTs that are proposed to be used in ‘Information and Communication Technologies (ICT) in Education for Development’, Global Alliance for ICT and Development, White Paper July 2009. 21 Srinivasan Ramani, International Institute for Information Technology, Bangalore, e-Discussion with Community of Practitioners at UN Solution Exchange (Communities of Education and ICT for Development). 20 17 ICT in School Education (Primary and Secondary) 2010 the school. Further, the contracts of procurement of ICT products could include among other, a short-term handholding feature with respect to familiarization and effective usage of the facilities.It is also suggested that the Teachers Training Institutes (TTIs) shall ensure ICT-based teaching and learning methodologies be integrated into the educational streams and build capabilities to the next-generation teachers with the capacity to handle ICT facilities with ease. Support of school administrators and, in some cases, the community, is critical if ICTs are to be used effectively. In addition, teachers must have adequate access to functioning computers (or other technologies) and sufficient technical support. Shifting pedagogies, redesigning curriculum and assessment tools, and providing more autonomy to local schools all contribute to the optimal use of ICTs in education.Creative Solutions to Computer Shortages Computer-based ICT interventions require significant investment in hardware. In addition, the expected active life of a computer is about 5 years, and as the hardware industry develops more sophisticated products, the software adapts to the top-of-the-line products. Computer recycling is an ecologically sound alternative to this problem. A growing number of not-for-profit organizations are dedicated to the tasks of collecting, refurbishing, and finding new homes for old computers. 22 In most South Asian countries, i t has been found that computer usage is most cost effective when placed in common areas such as cyber cafes, community resource centers, and so on.Alternative Power Sources Given the situation of power shortages in rural areas, and the effect of power shortage on the usage of computers and other technologies in schools, the Governments should actively promote the usage of alternate sources of power. This ecologically friendly solution will also ensure a steady power supply to schools in rural areas. For example, the Bangladesh National ICT Policy 2009 highlights the imperative of providing access to ICTs to all schools and using alternate sources of energy such as solar panels if required. Financing ICT Investments Financing mechanisms for ICTs in education initiatives are quite varied. Due to the high up-front costs and large recurrent costs, countries and communities typically employ varied models of financing and cost recovery mechanisms.Public-private partnerships and user fees are important components of financing ICTs in education in many countries, although more research is needed to determine the impact and effectiveness of these mechanisms (refer Annexure II for details on PublicPrivate Partnerships [PPPs]).

As a result, those with access to ICTs have been greatly empowered, and now believe they ca n compete in a global knowledge-based economy because they know that their knowledge, ideas, culture, and passions are as valuable as any in the world. In order to more effectively prepare students to participate in ICT-driven education, greater commitments and willingness to share and adopt innovative solutions are needed from all aspects of society—from Governments, the private sector, communities, donors, parents, and students.Schools should be transformed into active learning environments open to their communities; telecommunication and power infrastructure policies should focus on schools as starting points for rural transformation; teachers and students must be empowered to be creative agents for change in their schools; and leaders must embrace a vision that will prepare their youth for tomorrow’s challenges. 23 Despite the challenges outlined in the paper, ICTs are being increasingly used in education in both the developed and developing world, in order to reac h out to children from poor and remote communities, provide them with a quality education, and in general equip both teachers and students with a wider range of educational resource and enable them with greater flexibility. However, the growth and success of ICTs in education depends on the extent to which the issues and challenges outlined in this paper are addressed.There is a critical need to document every effort for the benefit of the various stakeholders— decision-makers, institutions, NGOs and civil society. It is necessary to know what works and what does not, and what the implications are for policy making, planning, and implementation. Specifically, it needs to be understood that any new technology comes not merely with hardware and software, but with a learning and teaching style and grammar of its own, and that management practices need to be adapted in order to use the technologies effectively. ICTs are, ultimately, only physical tools, which by themselves cannot bring benefits to students, teachers and communities at large.Therefore the unique contextual realities of this region, including, primarily, the initiative and impetus of the various countries and its constituents, the involvement of private companies and NGOs, and the level of infrastructure, play determining roles in creating enabling environments promoting the use of ICTs for primary and secondary education. 23 Robert J Hawkins ‘Ten Lessons for ICT and Education in the Developing World’, World Links for Development Program, The World Bank Institute. 19 ICT in School Education (Primary and Secondary) 2010 Bibliography ?

Monitoring and evaluation of learning gains, teaching practices, classroom environments, students’ participation, and other activities are required and necessary for addressing ICTs-enabled educational quality and access.However, one of the major hurdles in assessing these indicators was that the majority of the programmes and projects implemented did not have adequate quantitative or qualitative monitoring or evaluation activities. Further even if any monitoring and evaluation activities were conducted they did not adequately measure indicators pertaining to ICTs enabled educational quality and access. Monitoring and evaluating of programmes and projects are critical to ensure projects achieve their intended impacts and become sustainable in the long run. Appropriate indicators must be identified for every ICT project that can be monitored in order to effectively track progress.Stakeholders at all levels must be part of this process to e nsure transparency and to avoid potentially corruptive practices throughout the projects. Together with Aptivate, a UK-based NGO providing IT services for international development, Camfed, a NGO improving girls’ education in Zimbabwe, Zambia, Ghana and Tanzania, has tested the efficiency and quality of personal digital assistants (PDAs) as a tool for monitoring and evaluation. This method is extremely time efficient. Data can be calculated within hours rather than weeks and through its ability to connect to the Internet it can be transmitted directly from the worker in the field to the headquarter. 4 Supply-side based development models which are based on centralized designs and make â€Å"top down† assumptions of people (â€Å"teachers are resistant to change† or â€Å"lethargy of management†) have been tried several times and have not been found to be successful. Hence, a â€Å"monitoring and evaluation† theme that does not situate itself on the needs for professional development of the teacher, based on principles of autonomy, an agency can end up emphasizing centralized databases that seek to â€Å"control† teachers work based on quantitative assessments of children performance, which can be counterproductive to meaningful education. 25 This is not to deny the importance of â€Å"infrastructure† or â€Å"content† or â€Å"capacity building,† except o state that these perspectives appear to reflect an dominant â€Å"ICTD† kind of thinking which is mostly â€Å"supply based. † â€Å"We have ICTs so let us see what we can do with them† such ‘Information and Communication Technologies (ICT) in Education for Development’, Global Alliance for ICT and Development, White Paper July 2009. 25 Gurumurthy Kasinathathan, IT for Change, Bangalore, Solution Exchange for the ICT for Development Community, 31 July 2008. 24 21 ICT in School Education (Primary and Secondary) 201 0 approaches do not proceed from the identifications of the objectives to be met, or critical challenges to be faced, from the respective domain’s perspective.They seek to thrust some overarching technological world views on development domains whose enormous contexts and complexities, challenges, and goals are not given the prime positions as drivers of the policy. Some suggested evaluating parameters that may be applied to monitor the effective implementation of the policy on ICT in school education are as follows26: ? Are the ICT-based methodologies in sync with the existing traditional teaching? ? Does ICT facilitate the teacher in teaching better? ? Does ICT help in explaining abstract concepts? ? Does ICT make learning more exciting? ? Does ICT prod the student to know more, beyond the classroom? Does ICT make the student understand better and recall lessons taught during his absence or in manner alien to him or her? ? Does ICT make learning more participative and encou rage group learning? ? Does ICT support interaction? ? Does ICT ensure continued progress through enhanced learning? ? Is the ICT-based solution a textbook page turner and contains too much of textual content? ? Is there an excess on animations and cartoons? ? Are the animations too trivial or too complicated? Annexure II Public-Private Partnership in ICT Collaborative initiatives in the manner of PPP, to promote ICT for education may be most relevant at the implementation level, where select key roles and responsibilities may be outsourced in order to make them more viable and efficient.However, one needs to be vigilant about partner-institutions, which may have direct business interest in the value chain while the outsourced role on which they are inducted might enable performance of roles that may conflict the overall interest and purpose of the initiative. Moreover, there is also skepticism about the degree to which the ability of such partnerships under PPP arrangements will wo rk to reach interior rural areas and conduct operations on the scale required. 27 If the Ministry of Education has to solely take on this task of equipping the schools with ICT facilities, it would be an enormous task and will require funds in large sums.Therefore, M.

The most common type of agreement is â€Å"seeding fund† partnerships with emphasis on front-end costs and mostly capital costs.However, such an approach tends to underestimate the total cost of owners hip (TCO) of computers and other ICT equipment, which includes recurrent costs such as ongoing hardware maintenance and upgrades of hardware and software in addition to initial capital outlays. Also, teachers have to devote additional time and effort to lear
