Why is it necessary for schools to implant half day classes only?

necessary in OTHER schools:

if school is small and there are many students, the students can learn more things than whole days

the teachers can rest

the students will be "matutukan" than whole day because the class is divided

teachers can have time for the grading the students after class. It is also unfair for the teachers to compute the grades of the children in their vacation

the subjects are still gotten

the traffic in the afternoon is mild

the child can eat more healthy food if in home

the teachers held more meetings

high school department should have half day because they work harder and they are harder to manipulate and the teachers get more stressed. Some work part-time

and it is hard to work on school days. Research shows that 65% of teachers working on half-day classes are not stressed

half day classes can make the expenses of the family lessen and the child can have more bonding time with his/her parents
