I'm good with a bit of homework when the kids are not too little; there's something to say for sitting down by yourself and trying to focus and figure things out or memorize a little bit (it can be done at school too or instead of at home); if students don't have a minimum of study habits, how are they going to go about hard STEM courses in universities?
