What drives education policy?

According to this report the more school pupils use computers at home and school, the less well they do on tests of literacy and maths.

These findings raise questions over the UK Government's decision, announced by Gordon Brown in the Budget last week, to spend another £1.5 billion on school computers, in addition to the £2.5 billion it has already spent.

It's clear that whatever is the basis for the government's obsession with putting computers in schools, it's got nothing to do with educational outcomes.
