Much is made of the necessity to 'scale up' in international development circles. Here at the World Bank, a quick search on our web site reveals publications and conferences with titles like Scaling Up Knowledge Sharing for Development, Global Scaling up Rural Sanitation Project, Scaling Up Local & Community Driven Development [pdf], Directions in hydropower: Scaling up for development, Scaling Up Affordable Health Insurance, Scaling up School Feeding -- the list goes on and on (and on). 'Scaling up', it would appear, is a goal (and a challenge) across pretty much all development sectors. How can you achieve 'scale'?
It can be deceptively easy to propose a solution to a problem when you don't really understand the problem (especially if you think you do!). The 'failure' of many projects to introduce new technologies in education can, to some degree, be traced back to this simple truism. If you are pointed in the wrong direction, technology can help you move in that direction more quickly. To paraphrase the technologist Bruce Schneier (who was himself paraphrasing someone else): If you think technology can solve your education problems, then you don't understand the problems and you don't understand the technology. The solution lies in process and systems -- and people. Technology can help in all of these areas -- but first we need to make sure we understand what it really is that we need to do.
