One of the problems with teaching is that there's a temptation to evaluate what we do in the classroom based on how clever it aligns with a larger philosophy , or even how gratifying it is to use not necessarily how effective it is...

~ Doug Lemov

There is no such thing a boring content. In the hands of a great teacher...even if as teachers we doubt that we can make it so...this doubt puts us at risk of undercutting it: watering it down or apologizing for teaching it.

~ Doug Lemov

...we spend a lot of time defining behavior by the negative that was inappropriate. These commands are vague and inefficient...Telling students what to do in a way that is specific, concrete, sequential and observable refocuses us on teaching.
