That's the problem with just about every well-meaning "computers in education" program, even more recent efforts like OLPC. The teachers have to understand the power of the machine and the insights and abstract critical thinking that can be taught through it. Most teachers are like the sort I grew up with: they would hold floppy disks by sticking their fingers through the hole in the middle. And they mishandled kids even more destructively, treating them like vessels into which it was their job to pour the curriculum.
