Sorry I can't cite the papers, but I recall that hardly any computer based projects in elementary education had any noticeable beneficial effect. This is what I would expect for any normal two or three hours per week computer use in school.
The OLPC project, however gives the kid a computer full time, and she has to use it just to read the textbook. Still, that's no pedagogic help until you add the camera and the collaboration capabilities. Suddenly, the computer is a mere tool to assist with a serious activity involving the student and engaging her mind and body. This is where I would expect a real effect, not by the presence of a computer, per se, but by the research and the process of developing a school report. It's the engagement that matters.
Of course, that's opinion, not science. The experiment is called OLPC. The results are still out. And double blind is not an option, but real science is. No matter how you try to manage it, there will be differences in approach and differences in outcomes. Just look at what correlates. Schools do a lot of testing, but how well that measures the outcomes in fact remains open to question.
Incidentally, there was one year when the remote Stanford students actually did better than the ones on campus. Naturally they changed it immediately. The remote students had these advantages over the on- campus students: The VCR delivery of the lectures allowed the remote students to back up the tape to catch any missed phrase or whatever, and the teaching assistant that arrived with the cassette was happy to answer any student question, which could not have been asked in the lecture hall.
If some OLPC teachers can act like the teaching assistants and some course material can be provided as videos to be played on student laptops, perhaps that Stanford experience could be replicated. Still, I'm much more interested in the class project approach.

However, beyond such material, I get thoroughly confused by an inability to distinguish proven knowledge, accepted wisdom, and pure pseudo-science. It seems that a lot of educational research is done by anecdote rather than by controlled blind large group studies. Any pointers to the good stuff?
