Hi Chris: Being involved in your particular profession, I can see why you might view PPT as a flat, dull, sterile presentation media. In many ways I agree. I think just becasue PPT exists and can do a lot of presentation tricks with little training, it tends to get over used, while the poor student has to endure these "masterpieces" of instructional delivery. What you describe (digg.com) is more progressive and suggestive of the teaching concept of facilitating instruction, rather than being the provider of it. The more participative and engaged we can get our students, getting them involved, the better they will retain and learn, and use the knowledge gained from the class. In fact, if we could have the students teaching the class, how powerful and meaningful their educational experience would be. Regards, Barry
