What they really need is scientific and strategic thinking on how to take their life ahead, manage the village life, their farms more modern and productive, etc. in a smart way, etc. Simply throwing computers and computer education around without first giving them the fundamentals does not help at all. It just adds to the problem.
That said there are many ideas:
Write or install software where they can create friendly quiz for each other on various topics.
Teach them how to draw graphs and interpret them.
How to use maps.
If there is internet in a far away school, let the children interact with each other over Video Chat once in a month with proper agenda on discussing something important.
Really, there is no limit to how they can use computers to make their life more interesting and better , all limited by imagination.
