I think some things are done better now. There's no point in having the math teacher check your arithmetic, a machine can do that. Administrative stuff is also easier these days, things like recording what your homework is and communicating with parents.

But in general, why should we expect much improvement? School is mostly still a bunch of kids sitting around an adult, needing to concentrate. Having a computer means you don't have to lug around as many books, but it doesn't free you from having to read the books and do the exercises.

I'm not sure anyone was expecting a large gain from having the computers in the school to begin with, it's one of these things that happens because it gets cheaper as tech gets cheaper.
