I am a strong advocate for rethinking homework. I would go so far as to say that most homework assignments are not worth the teacher's or student's time or effort. A lot of homework is busy work.
Upon saying this, I've often been confronted with a very good question: is reading good homework?
It depends. I see homework as something to be inspired not assigned.
Whatever we ask children to do, be it at school or not, we must first ask "how will this affect this child's desire to go on learning?"
The child who can read but chooses not to holds no advantage over the child who can't read.
To stave off the development of a generation of alliterates (those who can read but largely choose not to) we need to care about whether children want to read at least as much as whether they can.
It's not good enough to simply say we will make kids read at home. We have to ensure they like it.
