I was recently struck with what I think might be a helpful analogy for teachers who are themselves perhaps wrestling with what to do about assigning homework. Here it is...
Imagine, teacher, that your administrator hands down an expectation that you are going to write detailed lesson plans for every single thing you teach. You are expected to do this every single day, and must submit them by 7:30 a.m. every day. If you are late, or if your work is incomplete, you will have to give up your lunch hour as a consequence. Every once in awhile, you get a stack of your lesson plans back from your administrator with "10/10" or "B+" or "78%" written on the top of them, but with no other comments, written or verbally submitted.
How would you feel about this situation?
