Why should school hours be shorter?
As I was studying in my college years, we tackled about the importance of having shorter hours in school and few of its benefits are the following:
- Children learn best through play which means that it does not necessarily to be in school which promotes lecture-type of class.
- Children nowadays have shorter attention span thus, eventhough, we have lenghty of school hours, children may not absorb all the information given on that day.
- To have more time with the family and other aspects of life.
Number of hours need to be considered according to the grade of students. However as you mentioned it should not be too long for anyone. They should have enough time to play and work on their other hobbies too. I think there should be a mix of all to get the benefits of education system without allocating many hours for studies only.
