Well, I don't know if what I do fits what you're interested in. I have done a series of network studies that look at student-to-student interactions, and how the way an instructor has structured the class affects their interactions. This is for distance students communicating almost totally via computer media. For a recent paper, see http://alexia.lis.uiuc.edu/~haythorn/hay_ICA01.html. If this fits what you're interested in, I can discuss this with you further. /Caroline Haythornthwaite Rick Grannis wrote: > I'm a researcher at RAND and I was wondering if anyone knows of studies, > data, etc. analyzing a teacher's ability to manage a classroom as a function > of the number of potential interactions among students. > > Rick Grannis
