Slides distract attention away from the instructor and away from what is written on the board. The instructor should be able to communicate important and difficult concepts using words and body language. Slides distract the instructor s attention from the students. If the instructor is spending time clicking to move the slide show along, he isn t paying attention to the audience's level of awareness and connection to the material.

Its important that I get things wrong from time to time, so the students can point it out to me. In this way, I can measure their level of understanding and attention.

As an instructor, I can recognize when the author of the study guide has gotten lazy and decided that the subject doesn t need to be discussed coherently.
