the hours spent at school are always constructive.the curriculam is planned for children to exercise both body and mind.to most parents, longer hours in school would mean that the children are being kept busy, studying or playing under the teacher supervision.
once without supervision at home,many children tend to spend their time in less worthwhile pursuits.for this reason,some people argue that school hours should be made longer.
on the other hand,the children must learn to get away from the school and friends.to think and learn by themselves is an important way to become independent.besides,too much of anything can make a person dislike it or become bored.so if we extend school hours,children might become dull or listless or even develop a strang dislike for school.
