A lot of students are in love with their highlighters, especially those bright, fluorescent-colored ones. They use them to highlight course materials, sometimes underlining whole pages of text. When I first saw a text so fluorescent that it all but glowed, I wondered why in the world somebody would spend that much time underlining. Later I understood it was really a cry for help. “I can’t tell what’s important, so I’ll just highlight the entire section so I don’t miss something.” Highlighting can be a useful way of interacting with text, but it needs to be done in a thoughtful way.
