Thanks to all of you for your very helpful suggestions and inspiration. Lots to do! As an aside, I'm going to adapt some of these approaches to a computer music class -- which typically has 6-8 students. I think I'm going to have them learn a certain application in twos. All this is very stimulating. Best, Anna HelveticaDr. Anna Rubin- FA 519 410-455-3190 University of Maryland/Baltimore County (UMBC)
