Hi Douglas: In instances where the institution decides how classes are structured and media resources utilized, we're given the opportunityy to be creative with what we've got. PPT's can be helpful if they're not relied on as the sole source of information (that should come the the instructor-expert). Also, PPT's can be a starting point for discussions, student led reviews of material, and even lesson reviews. There'd really a lot that a well constructed PPT can achieve. Regards, Barry
