Well, yes and no. The real evidence, and it is extremely interesting,
begins with a study by Dubin and Taveggia in 1968 "The
Teaching-Learning Praradox", Center for the Advanced Study of
Educational Administration, University of Oregon, 1968.
Their study, repeated a number of times since, showed conclusively that
there is no measurable difference among distinctive methods of
university instruction. Lectures, small group teaching, "Socratic",
self-study, you-name-it: the method of teaching and delivery simply
made no measurable differences.
You can read a nice summary and analysis of the situation at
After their bombshell, several methods of teaching WERE shown to have a
measurable effect, but the methods were independent of delivery
methods: I am referring to the Keller Plan and various forms of
The Point? Computers *can* be an effective delivery platform. A $100
computer *could* deliver much more educational material than a similar
amount spent on books or on real teachers.
Caveat: Dubin and Taveggia were talking about university level
education. I am no expert on child education, and I don't know what
level the OLPC is aiming at.
As an aside, it is very disappointing that university staff generally
do not believe that any of the above applies to their discipline.
