OK I have to admit I haven't read everything and I'm on the pro-homework in the sense of extending learning in school & timely, targeted practice to improve understanding/ skills.
What I've liked about the debate:
agreement that mangeable, age-appropriate work for the child should be assigned (idea that the homework should be achievable by the child on their own).
idea that optional homework (so giving parents the freedom to opt in or out of homework is available) - have to say a nearby school went optional and uptake was 97% across the entire school (3 forms each year).
agreement that project work often ends up involving the parent more than the child and may not necessarily be transmitting good habits/ attitudes/ experiences to children & can be stressful to busy parents.
What nobody (admittedly haven't read it all) seems to be saying is that it's a balance - there needs to be time for children to muck about doing nothing useful, time for chores, time for play, time for parties/ play dates, time for family time (cooking, cleaning, working in the garden, playing games, doing puzzles, watching a favourite tv show together, etc...) and time for reading for pleasure.
I do think many parents however are making a mistake that all homes have a wide range of books/ reading material available or regularly provide children with the opportunity to visit a library.
I'd love to go to our local library - it's a really sweet place - but it's opening hours don't work with my life - can't get there in time during working week and it's a rushed visit at the weekend because DDs have swimming at different times which means most of a.m. is lost to hanging around the swimming pool.
Finally nobody is saying it - so I will. I had homework in primary - maybe 5- 10 maths problems, a reading book (we were told read 5 pages, a chapter, etc... from a young age) and projects (little assignments - often about US history - so presidents, bill of rights, constitution, first colonies, etc...) - and I adored it all. Our projects were achievable - maybe a map sent home with the assignment that we were to colour in the first 13 colonies (later states) and find out their capitals. Yes, my Mum helped by getting out an Atlas and helping me to look up things at age 8 - but I really enjoyed this process. I liked books and learning and getting a star on my homework.
So although I totally respect many of the excellent reasons against homework - I just thought I'd add I was that kid that loved homework and couldn't wait to get home and start in on it.
