This Fall will be my 21st year teaching at the College of Mount Saint Vincent and I have still not figured out my homework policy. If I don't give any homework, students will not see any Math in between our sessions (up to 5 days!). If homework is assigned, I do not have any way to know who is doing it and who is copying!
At the K-12 level, homework can be an opportunity for families to help their students if and only if they have the time/knowhow/language etc. But homework is forward facing as it can show families what they students are learning as Horn mentions "Schools that do successfully eliminate homework may need to find other ways to signal curriculum rigor and communicate with families about what students are learning."
