Highlighting considered harmful?

As our students were reading silently (see yesterday’s post), teachers were strongly encouraged to model the process by silently reading the same book along with the students. We were meeting in homerooms — eleven or twelve students per teacher — so this was straightforward and visible. I was using a yellow highlighter as I read (“active reading”).

A colleague, on seeing this, claimed that research shows that highlighting is harmful. Supposedly underlining is better. I was surprised to hear this, and I’ve been unable to find any research that supports this claim, or that in fact makes any distinction between highlighting and underlining. Can any readers point me to such evidence?
