Moreover, I want them to understand the principles so well that they'll have some strategies to cope with the stress that arises from Pavlovian conditioning. I can identify several characteristics of good pedagogy that contribute to meeting my goals. Courses should be structured so that students interact with material in a pedagogically sound way. Finally, this should all be accomplished in the most parsimonious way. Here's a comparison between electronic communication and PowerPoint on these five key pedagogical characteristics.
Students are the active users of the technology.
They construct what is said, and actively synthesize the course material. PowerPoint is teacher-centered. It puts the instructor at the center of the action, promoting passivity on the part of students. Whether students are attending or not is incidental to using PowerPoint. Students decide when and where they interact with the course material and each other.
