Shawn,
I think PPT slides are best as an outline that touch on major categories and provide a forum for the teacher to expand, amplify, discuss, or provide more in depth instruction. If I want students to read something, I will prepare that for reading (not copies of PPT). I feel I am the teacher, the subject matter expert. No resource or tool is better at sharing information than me. I can (and should) use supplementary resources and activities to reach the students, keep them engaged, and make the class interesting.
If so inclined you could break students into groups, and each group would be responsible for taking extensive notes on selected slides that would be distributed to the rest of the class. All students would be part of a group. This could aslo include additional reference material (web sites, text pages, etc.). When students are activly participating in their studies they will learn better and retain more.
