Re: PPIG discuss: Bimodality, cohort progression rates, aptitude tests

        You might want to look at the studies by Chi et al, that really
nailed down the influence of "self-explanation" in learning. I've never
worked out how I could use it in teaching, but the ideas are very
seductive and sound similar to your experience.

        I tend to use a Socratic method in my tutorials, where I ask the
questions and lead students to designing a solution. I find this works
very well for the good students, but the not so good ones hate it. They
don't want questions, just the answers!
