"HOMEWORK OR NO HOMEWORK??

Okay, this question applies to primary and elementary level (Grade 1-3). I need some general opinion on whether it is necessary for children at this level to go home with homework/reading assignments/etc or is it a sin not appropriate for teachers to give homework at this age level? What do you think? Wait, when I say "no homework" it means no homework at all.

The reason I am asking is because recently there was a hot debate in our school about the above matter. Some strongly believed that students should not be brooding on their school work once they go home and should be spending more time with their families whereas on the other side of the coin, some believed that students should at least review what they have done in school, thus homework reinforces students to study and review. 

Now note this, our parents don't share most of our opinions. Most (60%) parents that sends their kids to our school are working parents or to relate them in this context, I would bluntly say that they don't have or don't spend time with their kids. So through our survey, we noticed that 99% parents went for "Yes, homework!" and only 1% says "No, what for!" So to sum it up, some (fortunately not all) parents prefer seeing their kids get busy after school doing homework rather than they (parents) having to entertain their kids. Well, homework serves a point too -- so that our students don't develop a potato couch habit! So far, no research has proven that homework encourages academic success. What do you say??
