My two cents...Take what you can use and leave the rest...
I think we should define "homework" because some teachers assign work such as "read for 15-30 minutes" (depending on grade level) which, upon further explanation, can be done over the course of time (evening/weekend) with road signs, books, McDonalds menu, whatever. Other tasks assigned may include "write a paragraph about your favorite after-school activity". These teachers also expect the parents to let them know if the assigned homework is taking "too long" or "too much of a chore". The teacher may expect a detailed explanation of what is going on, but modify "homework" as needed on a per student and their individual needs basis. Are we truly saying these teachers shouldn't assign any homework - even these tasks? What about those teachers that assign tasks like those found above with a full week's notice? Are we still completely "no homework"?
Also, while I agree with the "unplug before drug(s)" as I have lived with what used to be called "hyperactivity" - now ADHD - my whole life without drugs, I also believe good teachers assign a responsible amount of homework that supports the students' learning. If we don't complain about our kids going to practice a sport, why should we complain about our kids practicing what they learned in class that day/week/etc.? I also believe that those responsible teachers need parental feedback about how each student does with the assignment(s) as the teacher isn't at home with each student. For our children to excel, parents, teachers, and whole communities must work together to support their continued education. Learning is not just for the six hours at school that they "can barely get through" especially when one considers that actual amount of time they actually receive true core subject instruction. I don't believe we can count recess, lunch, bathroom breaks, travel from location to location (such as lunch/bathrooms), etc.
Finally, while I agree many teachers put too much pressure on students or rely on homework to actually teach, other teachers do use homework responsibly to support what has been learned in the classroom. Shouldn't we support these teachers, scream for more like them, and get rid of those who pressure our kids too much? Instead of "get rid of homework", maybe we should be more demanding of effective teachers who are responsible with homework assignments and less tolerant of the teachers who are ineffective for whatever reason.
