Many parents seem to think that more homework means the child is learning a lot. Thats a wrong and traditional impression. Modern syllabus like CBSE-i make an attempt to induce research based education which is much different from 'mugging up' for exams. But this type of scientific teaching is not very popular among parents because parents want to see the children loaded with home work and be satisfied that child is 'doing a lot'.
What they dont see is how much of that homework actually helps the child's intellect.
