Most of my professional reviews over the years have included an observation that I "entertain as well as inform." I spent many years teaching middle school, which can consist of a notoriously tough crowd, but I tried to make my class a place that each student would look forward to attending. When students were absent for one reason or another, they were always worried that they were missing something fun and interesting. By and large, this eliminated many of the problems that typically difficult students brought to other classes.
