Policy-makers, development specialists, and educators around the world generally agree that information and communications technology (ICT) can greatly enhance learning and more efficiently and effectively deliver educational services. In 2011, technology-based education (“edutech” or “ICT4E”) experts talked a lot (and debated a lot) about how to successfully implement ICT initiatives for education in developing countries.

Cost of implementation continued to be a top issue of concern, but the debate shifted from being solely focused on the cost of gadgets (“hardware”) to taking into account the total cost of implementing ICT education solutions. This includes teacher and student training, support and maintenance, and the cost of replacing the hardware. Many in the ICT4E field have opposed the fascination with developing the cheapest educational device possible, a mentality that grew in the late 2000s with projects such as One Laptop Per Child (OLPC). Now-a-days, ICT4E’ers argue that what is needed is not to try and reach the unfeasible goal of getting a laptop into every primary school child’s hands, but for each classroom to be equipped with a “learning system,” such as a teacher-centric computer connected to low-power projector.

While acknowledging that hardware is not the main cost in implementing edutech projects, it’s still interesting to see how low the costs of education gadgets can get. The ICT4E sector saw several new low-cost gadgets unveiled this year.

The education gadget that has perhaps received the most press this year is India’s Aakash, launched in October and developed by the company Datawind and the Indian Institute of Technology. DataWind CEO Suneet Singh Tuli recently gave a talk about the device at the World Bank, discussing its functionality, cost (subsidized at $35, unsubsidized around $60), and how it fits into broader sustainable business models of ICT adoption in the developing world. Many are critical of the Aakash; similar low-cost devices had been promised for India before and failed, and some questioned whether the tablet could really be considered “educational.”

Though Literacy Bridge piloted its $10 Talking Book in 2009 in Ghana, the non-profit has expanded the reach of the audio device as well as contributed to ICT in education strategies throughout 2011. The organization claims their device is “the world’s most affordable, durable, audio device” designed to reach people who are not literate and live without electricity. The gadget enables teachers to reach more students; for instance, they can record readings of instructional materials onto the device and create interactive audio lessons like quizzes or games.

Next year holds some exciting potential for ICT4E developments. Something to look out for soon (originally set to launch this month by a UK charity) is the Raspberry Pi, a tiny and incredibly cheap ($25!) computer that will be used for teaching computer programming to children. The Raspberry Pi Foundation plans for the credit-card sized device, which can be plugged into a TV, to have a number of applications that can be used both the developed and developing world.

Geeks Without Frontiers announced in August that it has developed a low-cost, open source Wi-Fi software technology that could reach a billion people in 10 years. The technology is estimated to be about half of the traditional network cost once it is up and running. Though it is not specifically designed for educational purposes, it could have huge implications for the ICT4E field, allowing many more students and teachers in low-income areas to connect to the Internet.

2011 also brought good analyses of all the low-cost gadgets that have been developed for educational purposes. One article looked at the best devices for education currently available, based on six success criteria for ICT4E projects in developing countries as determined by researchers and practitioners in the field: infrastructure, maintenance, contents and materials, community inclusion, teacher training, and evaluation.

No doubt the debates about the best way to implement ICT4E projects will continue in 2012, as will the search to find the lowest-cost educational gadgets. The field holds some exciting developments for the new year, so be sure to follow the Educational Technology Debate, ICT Works, the World Bank EduTech blog, and GBI’s education sector, among others, to keep up with the latest updates.
