Im a teacher too, i teach computer studies and i can totally relate to all what you have said, moreover there's a lot that goes on in the students home that is totally different from what we see in school, especially my part of West Africa where children hawk immediately after school with no chance of going back to read or revise what they have been thought, it gets more difficult for these students to relate with their peers during class activities and its a issue i face everyday. I hope parents will take proper steps in considering their wards or childrens education as topmost priority and educators can have better time while teaching
