I worked for a moron, who works for a moron, who decided the mark of a good teacher is to go beyond bell to bell teaching.
I have to clarify this. Not go beyond, as in do extra things for students, or with students, but as in start class before the beginning bell, and teach right up to the dismissal bell. You start class literally while you are in the hall, with an activity the students are supposed to immediately engage and embrace the moment they walk through your door. Of course, most never did.
