Molly expresses well some of the consternation we all feel at times with teachers who use PowerPoint ineffectively,
"I don't understand why teachers always make the classic black-and-white PowerPoints with a dash of a picture here and there. Everytime a teacher pulls up one of these presentations, it is my key signal to zone out."
Don't be this kind of teacher! I totally agree with Molly--don't give signals to your students to "zone out." A SAD (Stand And Deliver) style of teaching will often do that.
