This is a relatively well known technique already. In college, lecturers/professors often deploy it - we students would do the reading & research, then present the topic to the class with interactive questions where possible. (We didn't ever worry about not quite getting it right, perhaps because the prof was there to correct us.) It works fairly well for the actual sub-area you're assigned to work on, but you don't learn so much about your teammates' sub-areas (expectedly). And you learn even less from other teams' presentations, unless you're an excellent learner anyway.

Still, it's a good reminder to take the teaching approach wherever practical.
