The most popular answer to the question of how to improve the quality of schools and education in developing countries is: Invest in more teachers and more schools.

Let there be more teachers

I think there are few people who would contest that having one full time, fully qualified teacher in front of every class of 25 children would bring education of the highest standards to any country.
But could this really be the solution to the educational problems in poor countries? I sincerely doubt whether this solution is feasible. I even fear it is completely impossible to solve the plight of education in the developing world by this route alone.

Here is a statistic that paints a bleak picture, indeed:

India has one of the lowest ratio of teachers. In the US, it’s 3,200 teachers per million people, in the Caribbean it’s 1,500, in the Arab countries it’s 800 and in India it’s 456 teachers per million people. The Times of India (2009)

The US might not be the best example, but even to get at the level of the Caribbean, the Arab countries must double their number of teachers, and India must more than triple its number. And that would be just the number of teachers needed to get at the level of the Caribbean. If the teacher pupil ratio should get close to that of the US, double the number of new teachers would be needed.

Obviously, if the aim would be to decrease the number of pupils per teacher in all developing countries to the level of the developed countries, enormous numbers of teacher would have to be recruited and trained. For many countries in the developing world the number of teachers would have to double, like in the Arab world, in others it would have to triple, like in India and many African countries.

A lot of numbers

How many teachers would have to be recruited, trained, and send to schools? Below, a lot of statistics will be presented. If you are already convinced, you can skip the arithmetic and go to the next section.

Let us look at the numbers, some of which are collected in the table. For OECD countries there are around 16 students per teacher in primary education (CESifo DICE Report). Looking at the numbers, we can take a national average of 15 pupils/teacher as the norm for primary education in developed countries and 13 for secondary education. But note that these are just very global statistics on education. And keep in mind that worldwide, approximately 100 million children that should be in school are not.

Furthermore, as these statistics are global, they do not tell us how the available teachers are distributed. The developed countries are able to organize education in such a way that all children have comparable access to education. The difficult situations in the developing world make that the already low number of teachers are also distributed unequally. The pupil/teacher ratio can be much higher in rural areas than in urban areas. So for many children, the situation is even worse than these averages indicate.

Just to get the average number of teachers in the developing world to the level of that of the developed world would mean that the number of teachers in Sub-Saharan Africa and South- and West-Asia must more than double. In other regions increases of over 50% would be required.

To get these numbers in a global perspective, there are currently some 58 million teachers in the world, 28 million in primary education and 30 million in secondary education (see table). If the worldwide average ratio of pupils to teachers should be reduced from 25 to 15 for primary and from 18 to 13 for secondary education, an extra 30 million new teachers would be needed (19 million in primary, 11 million in secondary education).

Even a more modest aim to get the pupil to teacher ratio to 20 in primary education and 15 in secondary would require some 13 million new teachers, world wide. And that is without increasing the enrolment ratios in primary and secondary education to 100%. That alone could require another 20 million teachers.

In conclusion, any attempt to improve education in the world by increasing the number of teachers must prepare to recruit, train, and deploy well over 10 million new teachers, and maybe even up to 50 million new teachers. Trainers are needed to train these new teachers. If we are in a hurry, we would have to train them in, say, 6 years for a 3 year teacher training program, that would make 4-13 million new teachers a year entering training. This training program would require anywhere from 130,000 – 400,000 trainers for these teachers.

Round numbers:
13-35 million new teachers: Recruit, Train, Deploy
40 million teachers: Retrain
150,000 – 250,000 trainers for these teachers

Can we really rely on training more teachers alone?

Obviously, the numbers given above are rough ballpark estimates. But it is clear that “invest in teachers and schools” often means “double or triple the number of your teachers”. A truly gargantuan task.

There is an important question that has to be answered before such an effort is undertaken.

Why is it that there are not enough teachers in the first place?

It is not that training teachers is an unknown art. Teachers have been trained for a century now. Why is the world short of tens of millions of teachers?

It is not for a lack of trying. Ever since development aid became into existence somewhere after WWII, it has been known that more teachers are needed. But somehow, the developing countries have been unable to supply them. There are many reasons for this shortage, underfunding, bad working conditions, labor migration away from rural areas, competition from other employers, low social status, bad organization etc. These are social problems. And we know that social problems are the hard problems. And there are as yet no convincing ideas on how to solve these very hard problems.

So, that is why I think any plan to “invest in teachers, not technology” is bound to fail. There is simply no known policy that can solve the problems that plague teacher recruitment and training in less than a generation, if they can be solved at all. Trying to recruit and train millions of new teachers is simply going to fail. Any attempt to just throw money at the problem will fail just as badly as all the other cases where a solution was dropped on the developing countries.

I like the idea of supplying every child with a well trained teacher in a class with only 30 pupils. My sole objection is, it cannot be done. And even if it could be done, what should be done for the children that enter and leave school in the meantime?

Technology to the rescue

Compare the problems of supplying children with teachers to supplying them with technology. If we would supply the roughly 900 million children in dire need of education with OLPC laptops over a period of 5 years continuously, this would cost around $40B a year, worldwide. (200 million laptops a year at $200). I can write a small encyclopedia with all the objections to spending $40B/year on OLPC laptops. But we all know that it is actually possible to produce and distribute 200 million laptops per year. It costs money, but it can be done. This is technology, and technology is easy.

As education will have to rely on the existing workforce for the foreseeable future, their work, and that of their pupils, should be made as easy and productive as possible. In a service industry like education this means using technology, i.e., ICT. But we should not forget that a lot can be done using less glamorous technology. For instance, in many regions in the world, a bicycle may improve mobility of children and teachers alike and enable children to continue further education (Indian Times, 2009).

Without light and heating, education would have to be curtailed severely during the winter in my own country. But such measures, e.g., electrification or increased mobility, have obvious positive impacts on economic development. Such measures do not have to be argued. Here I would like to concentrate on ICT4E, the advantages of which are much more contentious.

ICT4E has the same problems as ICT4D(evelopment). It is inconceivable that a solution to every local problem could be devised by a person sitting behind a keyboard in Western-Europe. People on the ground, locals, know what is needed and what is available. Bicycles can help some children get to school in the Netherlands or regions of India, but it would be a complete waste to send bicycles into other areas, e.g., the Andes or Himalaya. However, there are many “simple” problems that crop up everywhere in the world, and might be solved by a single tool or technology. Just like the blackboard solved a problem experienced in every classroom in the world, there might be technologies that are valuable everywhere.

In our quest to look for eligible technology, I would like to stick to ICT solutions that avoid the “Top 7 Reasons Why Most ICT4D FAILS” (Rogers, 2010, a nice YouTube movie). The video explains it all so I will not repeat them here.

The central question is how to make ICT useful for schools. Received wisdom is that technology should be integrated in community life before it can be really useful. It is instructive to study cases where this received wisdom has been flouted. Prime examples are radio, television, and mobile phones. History has shown that these gadgets have been embraced by almost all communities, even those that lacked any understanding of the underlying technologies. In a completely different field, the simple formulation of Oral Rehydration Therapy helps local staff tackling one of the leading causes of child mortality in the developing world without lengthy training or expensive infrastructure.

The successful electronic consumer gadgets all have in common that they require zero maintenance and are robust in normal use. The only consumables of the gadgets are electrical power or batteries. A costly infrastructure is needed for all three, but this is both outside of the view of the consumers and the costs are shared by all.

These technologies fitted every human society because they were transparently enabling some of the most basic human needs: Exchanging stories, gossip, and news and playing music. This acceptance is not a matter of User Interface or ease of use. Text messaging on a mobile phone must count under the worst User Interfaces ever invented. But because the feed-back is immediate and transparent, even small children are able to put up with it (and often can do the task blindfolded).

So we need turn-key drop-in technologies that have zero-maintenance, are robust in the field, including fields of the green and grassy type, and latch into basic human behavior. Mobile phones might be the best examples, as they require little more than electricity and a (prepaid card) number. They are easy to carry and protect: Just keep them out of the rain or in a pouch. And they help people to do what they seem to like most, talk and write to each other.

A last feature of successful technology introductions is a long technological horizon. Anything that takes so much effort to introduce should last a long time. We can expect our children to still use something that functions as a phone or a TV. The actual device might look different, but we should be able to recognize the function. Especially in education, new technology should last a generation. The children of the pupils that are introduced to the new technology should be expected to use something alike. So if no continuous upgrade path is expected over the next decades, I think the introduction of a technology should be seriously reconsidered.

To summarize, the kind of technological solutions that I am looking for would fit all of the following (think radio, TV, and mobile phones):

• Solves a global problem or need
• Robust in normal daily use
• Turn-key drop-in
• Zero-maintenance
• Consumes only electricity, and very little of it
• Connects to content or communication channels (including surface mail)
• A long technological horizon

Note that the technological solutions discussed are intended to solve serious problems. Nowhere is it assumed that technology should improve education if there are no real problems. Technology does not replace a teacher, but it can help her teach and help the children learn.

My archetypal example of successful educational technology is the blackboard. The blackboard solved a huge educational problem in teaching for large groups: A simple, flexible, and cheap method to present text and diagrams to large groups of pupils. It allowed to effectively display and explain complex concepts so that children in the back of the classroom could see them too. It is a pity that you need chalk to write (a consumable), but that proved surmountable.

Two examples will explain these bullet points: The pocket calculator and desktop PCs running Microsoft Windows.

Pocket calculators, or better, graphical calculators, were introduced in secondary education in Europe at the end of the 1970s. The problem they solved was that some important mathematical concepts could not be taught because the calculations on anything but toy problems were too cumbersome. With these electronic calculators, realistic problems in statistics, matrix algebra, and function theory could be introduced into secondary education. As these calculators can be used in class and at home, their use can be easily integrated into the relevant courses. Moreover, pupils learned how to perform arithmetic on real calculators like they would need in working life later.

So using the calculators solved a small, but very real problem in the teaching of mathematics, economics, and science. Obviously, a pocket calculator fits all of the other bullet points. They run for months or years on a single battery, get their contend from the text books, and they have been in continuous use for over 30 years now. A clear success story.

On the other hand, desktop PCs in school running Microsoft Windows defy every bullet point. The only general problem that is solved by a PC in school is Internet access. But there is little use for direct Internet access in class. Desktop PCs can be used in courses directed towards computer use, but even that is hardly useful in school. At home, PCs do have general practical value, but that has little to do with the limited presence of PCs in school. Introduction of such desktop PCs in schools in the developing world generally ends in a deception.

An important problem is that Microsoft Windows has a tendency to break in daily use, especially when the computer has an Internet connection. The hardware of desktop PCs is not designed for a tropical climate. Moisture and dust can easily break the hardware. Installation and maintenance are difficult and require special skills and knowledge. Desktop PCs consume a lot of power and, therefore, cannot run on batteries. So their use is very limited in locations with unreliable power supplies. Connectivity is good, if a wired or wireless Internet connection is available. And they can be used with CD/DVD disks or USB memory sticks.

The technological horizon is more complex to judge. In future generations, we can expect to see screens, keyboards, and computers of some kind. However, I still remember a quote from a parent in the 1980s. When asked why she preferred the use of MS Dos PCs over Apple Macintosh computers in primary school she answered “Because when my child will go to work, it will have to use MS Dos, and not the fancy graphical interface of the Apple Macintosh” (paraphrased from memory). And it has been this way ever since.

If we look at the developments of computer use in the last years, we see perpetual shifts. Nowadays, the shift is towards a completely different model of computing with the integrated User Interfaces of mobile phones (iOS and Android) becoming the standard for tablets, netbooks, and upwards into other computers. So the technological horizon of standard desktop computers has always been very short.

An example of new technical gear: The OLPC XO

As an illustration of a recent project, compare the above with the OLPC XO laptop. The design goals of the XO laptop came very close to the ideal of a no-worry drop-in technology.

The software is distantly related to the Android mobile phone operating system with a zero-maintenance update and security model. The laptop was designed to be robust and the only consumable was electricity. The laptop was easy to carry and protect. It enabled access to the Internet for video and voice connections, email and Instant Messaging, and you could also use it to play music. Connected to the Internet, it could replace radio, TV, phone, and music player.

The laptops could double as book readers and store a complete library, allowing schools that could not even afford textbooks to get a library for each child. On top of it, it could also be used as a computer. The technological horizon looks promising as some kind of small, mobile computer with a simplified interface is likely to be around for the next decade or so.
What went wrong with the first version of the XO laptop?

Basically, the execution fell somewhat short of the design goals. Quite a number of laptops were rolled out before the software was finished and these laptops suffered from a lot of very annoying bugs. These bugs could not be solved by the normal update mechanism, but required replacing the operating system itself. The logistics of supplying a new operating system image to laptops in the field proved to be impractical.

On the hardware side, the keyboard was not robust enough and broke in too many laptops, as did the trackpads. And power consumption was still a bit too high for many locations. The mesh network to share Internet connections did not scale well inside schools and did not deliver the planned connectivity. Supplying Internet connectivity to schools proved to be the Achilles heel of the project. And without an Internet connection, the laptops became much less useful for their intended purpose.

In then end, the first generation of the OLPC XO laptops came very, very close to achieving the status of a no-worry drop-in technology. And where there was Internet, they seem to function as intended. But without a solution for the Internet connectivity, the laptops are much less useful. Had there been Internet connectivity at home, we can be pretty sure that the children would have found out how to use the keyboards and navigate the User Interface. If primary school children can find out how to send text messages on mobile phones without formal instruction, they can learn to use the OLPC’s Sugar interface.

But even if the XOs function as intended, there remains the logistic problem of giving out and replacing laptops and delivering electricity and Internet connectivity. In general, all technological solutions require logistics to distribute the gear (TV sets, mobile phones), the electricity (or batteries, or solar panels), and the connections (transmitters, cell towers). These will always be a problem for rural areas in the developing world. But these factors affect each and every attempt to solve problems in the developing world as they are at the heart of the economic under-development to start with.

As many technophiles, I really love the OLPC laptop. But I know that was not the question. What we really want to know is whether there is a technology that solves the problem at hand. However, this discussion is targeted at a global audience, and we know that the cost of technology depends on the production volume. The very first radio was extremely expensive, the billionth transistor radio is a free promotion item. So I will look here at global problems with high volume solutions.

Example of a global problem and solution: Textbooks fantasies

To illustrate the ideas presented above, I will fantasize about a real global problem in education and a technological solution.

Textbooks are a necessity in school, but they are expensive. My country spends around 300 euro ($400) a year per pupil on textbooks in secondary school. For this money, each pupil could get a laptop and a broadband Internet connection at home for the duration of her education. With some change to spare for electronic textbooks. Most of this cost is the result of monopoly rents by the publishers, as it is in many developed countries. But even at half the price, each student could get an ebook reader with a lot of money to spend on electronic books and prepaid mobile Internet.

The root of the textbook problem lies in the cost of production. Textbooks are a difficult market, with high investments in writing and printing and high distribution costs. And it is an all or nothing market. Either your book is selected for the curriculum, and you sell big, or it is rejected and you sell nothing. Moreover, to stay up-to-date, textbooks have to be revised very often. A lot of insider knowledge is needed to produce a textbook that fits in the standard curriculum. As a result, the market for textbooks for primary and secondary education is always limited to a single school system (country).

And in the end, the textbooks are not that great at all. Ansary (2004) gives an illuminating and entertaining, but also infuriating, account of the way text-books are produced in the USA. Quite often it is a pain to use these textbooks. Most teachers have to create extra “cheat-sheets” to supply missing material and explain incomprehensible portions of the text. Beyond all these problems with the content, there is the daily wear and tear of paper books that makes every textbook usable for only a few years, if well cared for.

In accounts of classroom practises in the developing world, we often hear of whole classes that spend their day copying the complete text of a textbook from the blackboard into their notebooks. This seems a waste of time. When copying large amounts of text, you are unable to think about the text or even remember it. However, supplying the books themselves to the children was obviously not possible. So copying a book wholesale might be the only way the children can ever get hold of the text. Still, we will all agree that it would be better if the pupils had the same textbooks as the teacher. The teacher could then spend her time explaining the material in the textbook and children could spend time learning and practising the skills covered by the textbook.

So here we have a truly global problem: Expensive, outdated, low quality, and cumbersome textbooks that are often not available for the children in the developing world. Can we fantasize about a better system? One that gets both teachers and children the books they so desperately want and need?

There is a very good idea that was actually embraced by (some) politicians in the developed world, the Open Textbook Initiative. Creative Commons electronic books produced by authors and teachers in Wikipedia style (Creative Commons, 2010; Beshears, 2005; Durbin 2009). In principle, this can be applied world wide. The ministry can give grants for writing specific electronic textbook, or volunteers and teachers can write their own. The textbook are licensed under some Creative Commons license that allows free distribution and adaptation. The books are archived and made available in a repository and distributed electronically as ebooks.

Teachers, scientists, and students can add and submit changes in Wikipedia style. It cannot be said that ebooks are better than paper books, but they will be preferred over no books at all.
And the costs? As I wrote above, for what the developed countries pay for textbooks now, they can supply top of the line ebook readers and Internet connections to the students, and have massive amounts of money to spare for grants to write the books. And if you ever tried to lift the school backpack of a high-school student over here, you know that ebooks would take a heavy burden from their shoulders.

In the developed world, the Open Textbook initiative solves kind of a luxury problem. The developed countries can actually pay for the costs of over-priced paper books. They just feel they do not get quality for their money. And often no quality at all. The question is, could such an Open Textbook initiative work in the developing world, where paper textbooks are problematic?

Here we have to look again at our technology bullet list. The Open Textbook initiative does serve a pressing need for good and affordable textbooks. We can be pretty sure that every teacher in the world would welcome better, up to date, textbooks. So, provided a collection of good textbooks can be produced by way of government grants or volunteer work, this part is covered.

Current ebook readers are constructed for indoor use in the developed world. They do have too many unprotected openings and fragile components for a developing world environment. However, covering up these holes and putting in more robust components is not very difficult, the OLPC has done most of that work already. For most ebook readers this would be a minor, and cheap design change, not a problem.

The use of ebook readers is quite simple. You drop in an ebook (or a shelf of ebooks) and you start turning pages. Apart of language and date and time there is not much to set. So, indeed turn-key drop-in technology. Theoretically, you can update the software of an ebook reader, but there is not often a need for doing that. An ebook reader can in most respects be considered to have zero-maintenance.

And last, but not least, ebook readers using electronic paper displays have extremely low power use. Their requirements are low enough to make charging with small solar panels feasible. Current retail costs for cheap ebook reader offerings are below $100 for consumers. Ebook readers cannot be repaired (easily) in the field, so any program to supply them should stock for replacement readers.

The next bullet point is connectivity: How to get new books on the ebook reader. Ebooks can be transferred to an ebooks reader by either connecting it to a computer which has them stored or downloaded, or over a wireless connection in the more expensive ebook readers. Most readers have a slot for external memory SDcards, which could be used to distribute ebooks. Even though SDcards might be rather fragile in daily use, they can be distributed over surface mail. So, the connectivity could be handled by sending USB sticks or memory cards with the mail or a messenger. There would have to be some outlet with a computer or laptop to transfer the new ebooks.

Sounds ideal, so why has it not been done yet?

Even at $50 a piece (gross price), a complete roll-out would be a rather big investment for a single purpose gadget. The cost would exceed the total educational budgets of many countries by a large margin. And the organization of a coordinated roll out of so many devices could overwhelm the capacities of most administrations. The cost and organization alone of an ebook reader roll out would exceed the resources of the countries that need them most.

Furthermore, the technology is all very new. If you roll-out ebook readers today, you might miss out on the powerful and cheap tablet computers of next year. A kind of, very realistic, economic deflation fear. So the technological horizon is short, very short indeed with all the new tablet computers coming out. Ebook reader apps are already part of every new smartphone. In a few years time, separate ebook readers will cease to exist and a general mobile platform will have taken over their function.

There is also the chicken-and-egg problem of needing electronic textbooks to use an ebook reader in class, while these textbooks will not be produced if the children have no ebook readers. On the other hand, if there is one thing that can be learned from the history of the World-Wide-Web and Wikipedia, then it is that if there are readers, the writers will come. The real challenge is to get a national Open Textbook initiative going. This will be addressed in the next section.

Teaching the teachers: A program fantasy

From the earlier discussions on Educational Technology Debate, it has become quite clear that the real challenge is not to get cutting edge ICT4E gear in the hands of the children. The real challenge is to ensure that the teachers are able to actually make use of the technology in their lessons. The solution is simple to formulate: Remedial courses for the teachers. But the initial problem was that it was not possible to adequately teach the children. How can we then train the teachers?

First of all, there are much less teachers than children, and they can occasionally travel. So it should be possible to arrange some classes in (semi-)urban areas where it is easier to provide education for adults. On the other hand, children have ample time for learning, adults have other responsibilities. So any courses for teachers must be short, targeted, and effective. The main point is that a one week course during the summer break will not be enough to prepare for a large change in the curriculum including hitherto unseen technology. And for teachers too, it holds that education must be interactive. Simply dumping a large amount of documentation on them will not lead to them actually mastering the subject.

Let us assume some technological solution has been selected for a nationwide roll out. For the sake of argument, our fantasy ebook reader program is introduced in schools which lacked books. The ebook reader program is accompanied by a national Open Textbook program. Now, what follows is my fantasy of a teacher instruction plan to use these ebook readers. It is assumed that the Ministry of Education can hire some local (or international) educational experts to construct a basic curriculum and lesson plan for use with the textbooks on the ebook readers. These plans are the basis for the textbooks.

The current practise is that teachers do group drill exercises, e.g., children copy the teacher’s text book from the blackboard and memorize some part of it. Such drills normally would take most of the in-class time. The task of the training program is to instruct the teacher how to operate and use the technology itself. They should learn how best to teach the children the use and care of the technology. But this introduction to the technology is just the basic part.

The real training must be to instruct the teachers how to use the electronic textbooks in class. As copying and memorizing the text books has become an irrelevant exercise, there is time during class to do other things. So teachers will have to get an idea what these textbooks can be used for. The curriculum will be adapted to reflect the presence of the ebook readers. As other commenters have already remarked, this is not something that can be achieved in a mere 1 or 2 week course.

The solution would be some kind of continuous distance learning program. Any one-time out-of-town courses should be followed by refreshers over correspondence. This could be anything from surface mail of course materials and assignments, special magazines, to special (off-hour) radio and TV programs, phone-in sessions, and if Internet is available, live Internet chat or video conferencing sessions. Given that the whole program will cost quite a lot, a special, one time a week radio or TV show will not be that expensive. Tapes can be send to those who cannot listen or watch life.

For our ebook reader program, the reading and audio materials can be mailed on a USB stick. We can nicely integrate the distance learning course with the Open Textbook initiative. Instead of dumping the textbooks on the schools, it would be nice if the teachers would get a say in what would become part of the textbooks. So, part of the assignments could be to suggest improvements to the textbooks. Maybe write or edit paragraphs. And send back the notes. Nothing fancy, pencil and paper would already be enough. These notes can be processed by the editors of the textbooks. Best to keep a list of contributors at the back of the final textbooks.

Obviously, there is not a lot that can be done in the one to two years in the run up of a large roll out. Especially as the teachers will have their normal responsibilities and duties, which would already take up their time. A course with associated book, magazines, and radio and TV programs would probably be the best option.

This is a format that is used world-wide for teaching languages. There is a lot of experience with such TV/radio courses. The exact formulation will obviously depend on local circumstances and customs. The real advantage of such a program is that it can be produced and staffed by locals. Teachers “on the ground” can be interviewed, and radio shows can contain phone in question and answer sessions as well as listener feed-back. This is all quite ordinary practise in most countries.

It would be unrealistic to expect that all teachers will have opportunity and time to fully participate in the interactive and collaborative aspects of such a program. But the more teachers have a chance to be active in the program, the better it will take root. And for teachers too it will hold that peer instruction is the second best thing after teacher instruction. So if the program can reach a large fraction of the teachers, we can hope that their knowledge will diffuse through the whole community. And there is no reason to stop the information program after the roll out is completed.

Discussion and Conclusions

It is obvious that developing countries will not be able to double or triple their number of teachers in the short term. So for the next decade or so some solution will have to be devised and implemented to improve education for the children entering school. Beyond more teachers, there are only few options left. Technology is one of them. To increase the chance that the chosen technology will actually be effective, some precautions should be taken. Basically, the probability of success will vastly increase if the technology can be used and maintained by children for the intended purpose. Which is basically the main aim of the small bullet list above. Anything more complex or demanding risks being relegated to gather dust in a corner.

But after we have the wonderful gadgets and gear, it should improve education. As teachers will have to change their teaching habits, it is very advantageous to instruct them in using the technology to improve their lessons. Given the other obligations that occupy teachers, any face-to-face training courses have to be short. To make the changes permanent, an interactive follow up is needed over the months that follow the face-to-face courses. A large number of options exist for semi-interactive distance courses and follow ups: magazines and tapes in the mail, radio and TV with phone-in, or question sessions by mail or phone. All these are distance learning practises with a long history. Only think of all the language courses broadcast around the world.

Under-development and over-stretched schools have shown to be very hard problems to solve. Although some kind of technological progress will be involved in the eventual solution, it is still unclear whether introducing any single technology can actually help. But as technologies like radio, TV, mobile phones, and even Oral Hydration Therapy have shown, the dire effects of important global problems can be alleviated by introducing certain types of technology. With only limited instruction, I think it will be possible to find solutions to help alleviate some of the educational problems that result from a chronic shortage of qualified teachers in the developing world.

1. Mobile Learning: New advances in hardware and software are making mobile “smart phones” indispensable tools. Just as cell phones have leapfrogged fixed line technology in the telecommunications industry, it is likely that mobile devices with internet access and computing capabilities will soon overtake personal computers as the information appliance of choice in the classroom.

2. Cloud computing: Applications are increasingly moving off of the stand alone desk top computer and increasingly onto server farms accessible through the Internet. The implications of this trend for education systems are huge; they will make cheaper information appliances available which do not require the processing power or size of the PC. The challenge will be providing the ubiquitous connectivity to access information sitting in the “cloud”.

One-to-One computing: The trend in classrooms around the world is to provide an information appliance to every learner and create learning environments that assume universal access to the technology. Whether the hardware involved is one laptop per child (OLPC), or – increasingly — a net computer, smart phone, or the re-emergence of the tablet, classrooms should prepare for the universal availability of personal learning devices.

4. Ubiquitous learning: With the emergence of increasingly robust connectivity infrastructure and cheaper computers, school systems around the world are developing the ability to provide learning opportunities to students “anytime, anywhere”. This trend requires a rethinking of the traditional 40 minute lesson. In addition to hardware and Internet access, it requires the availability of virtual mentors or teachers, and/or opportunities for peer to peer and self-paced, deeper learning.

5. Gaming: A recent survey by the Pew Internet and American Life Project per the Horizon Report found that massively multiplayer and other online game experience is extremely common among young people and that games offer an opportunity for increased social interaction and civic engagement among youth. The phenomenal success of games with a focus on active participation, built in incentives and interaction suggests that current educational methods are not falling short and that educational games could more effectively attract the interest and attention of learners.

6. Personalized learning: Education systems are increasingly investigating the use of technology to better understand a student’s knowledge base from prior learning and to tailor teaching to both address learning gaps as well as learning styles. This focus transforms a classroom from one that teaches to the middle to one that adjusts content and pedagogy based on individual student needs – both strong and weak.

7. Redefinition of learning spaces: The ordered classroom of 30 desks in rows of 5 may quickly become a relic of the industrial age as schools around the world are re-thinking the most appropriate learning environments to foster collaborative, cross-disciplinary, students centered learning. Concepts such as greater use of light, colors, circular tables, individual spaces for students and teachers, and smaller open learning spaces for project-based learning are increasingly emphasized.

8. Teacher-generated open content: OECD school systems are increasingly empowering teachers and networks of teachers to both identify and create the learning resources that they find most effective in the classroom. Many online texts allow teachers to edit, add to, or otherwise customize material for their own purposes, so that their students receive a tailored copy that exactly suits the style and pace of the course. These resources in many cases complement the official textbook and may, in the years to come, supplant the textbook as the primary learning source for students. Such activities often challenge traditional notions of intellectual property and copyright.

9. Smart portfolio assessment: The collection, management, sorting, and retrieving of data related to learning will help teachers to better understand learning gaps and customize content and pedagogical approaches. Also, assessment is increasingly moving toward frequent formative assessments which lend itself to real-time data and less on high-pressure exams as the mark of excellence. Tools are increasingly available to students to gather their work together in a kind of online portfolio; whenever they add a tweet, blog post, or photo to any online service, it will appear in their personal portfolio which can be both peer and teacher assessed.

10. Teacher managers/mentors: The role of the teacher in the classroom is being transformed from that of the font of knowledge to an instructional manager helping to guide students through individualized learning pathways, identifying relevant learning resources, creating collaborative learning opportunities, and providing insight and support both during formal class time and outside of the designated 40 minute instruction period. This shift is easier said than done and ultimately the success or failure of technology projects in the classroom hinge on the human factor and the willingness of a teacher to step into unchartered territory.

These trends are expected to continue and to challenge many of the delivery models fundamental to formal education as it is practiced in most countries. It will be interesting to reflect back on this list at the end of the year to see which ideas have gained the most traction; and what new ideas will make a list for 2011…
