I'm 14 and my high school has a blocked schedule. My middle school did not. I can easily say that the blocked schedule has taken a lot of stress off of me. There is more time to learn things during the day because the class is twice as long, and there is more time to do homework. When there is more time I can put more effort and thought into it because I don't feel rushed. This is something that would be very beneficial to schools.
Yes because the school day would go faster. Students could have more time at home to work on homework. Teachers could give a short lesson to the students and then give them school work to do everyday at home. Students would have more free time after school and they would get a lot done
