Question

Teacher ratings of classroom disruptive behavior decline for children who have no recess. the threat of recess cancellation if any child misbehaves. 5 to 10 minutes of recess a day. more than 15 minutes of recess a day.

Answer 1

I believe the answer is: have more than 15 minutes of recess a day.
A recess is needed in school schedule in order to give the students enough time to rest and blow up their steam.
Without this, the students would most likely become vent up and opt to not pay any attention in the class, which eventually led to less productivity in class.
