My three favorites from this list are:
The Homework Myth by Alfie Kohn
The Case Against Homework by Sara Bennett and Nancy Kalish
The above two books are parent-friendly and this one is more teacher-friendly:
Rethinking Homework: Best Practices That Support Diverse Needs by Cathy Vatterott
I happen to have 2 copies of Rethinking Homework for my local friends. If you would like to buy one from me, please email me at KerryTeegen@gmail.com. The cost is $10.00.
