I teach online. When I do my powerpoints I use pretty pictures from clip art to enhance the presentation slides.
My students seem to specifically like landscape pictures. Sometimes, when what we are learning is complex, I put a "Moment of Peace" slide with a beautiful landscape picture. The students say they like it.
This module seems to suggest that an instructor should only use visuals with a relationship to what is being taught. But I teach medical records so the landscapes provide a needed respite. What would you do?
