Garr Reynolds totally changed my life with his “think like a designer” concept. Since I started learning about and practicing Reynolds’ slide design concepts, I see a noticeable difference in the engagement from my students. They don’t have everything that comes out of my mouth written on the slides for them. That means they have to pay attention in class instead of passively sitting back and disengaging. Effective slide design encourages active participation, learning, and thinking. Why wouldn’t a teacher want to employ this method?
