Here's my comment:
I would like to highlight the comment "Who is in charge of your house? You or your nine-year-old son?" and rephrase that to "Who is in charge of your house? You, your nine-year-old son, or your nine-year-old son's teacher?" The sad part of this common dilemma is that the authority of the teacher to assign and demand homework goes unquestioned. In reality, homework is controversial, teachers do not study the research, theory and practice of giving homework when they are in school, and they frequently miss the point about why an otherwise bright child does not do his homework. The key is almost always found in the issue of pace and that has to do with problems of attention, reading speed and handwriting speed. Children work with time containers at school, but with the expectation that they will keep working, without limits, until the work is done at home. This is unrealistic and unfair, and at the core of what I call The Homework Trap. But whether you agree with my analysis or not, take stock of the oversight in discussing whose in charge of the home, omitting the powerful authority teachers are given over what happens in an individual home. www.thehomeworktrap.com.
