The next time a proponent of homework says that they have to assign homework because they simply do not have time to cover all of the curriculum, ask them how much time would be sufficient. Ask them how much time are they shy? Ask them how much time would they require in order to properly get through all that is asked of them via the mandated curriculum.
There are likely two kinds of answers.
One answer is that they won't have a quantifiable number - which implies no amount of time would satisfy the insatiable appetite of the curriculum and homework monsters. If this is the case, perhaps we should rethink the entire idea of homework and maybe even curriculum.
Second is that whatever answer in minutes or hours they give will likely be less than the actual hours, days and even weeks of homework their students are actually assigned.
My point here is that we are not nearly mindful enough about the kind and amount of homework that is doled out to kids. It takes mere seconds for a teacher to assign it, but infinitely more blood, sweat and tears from children and their families to to carry out such homework requests.
