Answer:
I think schools should change the gym class ways so they can get more exercise.
Gym class may not teach anything academic but it keeps students active, and studies found that physical work is very important and it helps students learn that is is important. Gym is important just like science or math. Schools should take a healthy body or healthy mind approach to education.
A school should also teach life skills or a way to help students defend themselves.
What if you are walking home because you don't take the bus or a ride to your house and you get kidnapped? This really bothers me because the parent/guardian of the students should be teaching them that at home, but most don't and I would LOVE to see schools start teaching kids self defense.
That is all I could think of at the moment. Hope this answered your question :)
