Answer:
Pro: More Time for Other Subjects
A longer school day would allow schools to spend more time on art, music, social studies, science and physical education. These subjects have been cut back through the years to focus on English and math in the hopes of boosting test scores. Yet test scores have remained stagnant, and students have missed out on a more well-rounded education.
Con: Less Time for Outside Interests
The more time kids spend in school, the less time they'll have outside of school. This is time they currently spend on extracurricular activities of their choice. Students will spend time in a basic physical education class instead of dance, karate or listening to music. Children already spend a large portion of their day being told what to do, how to do it and what rules to follow, and have little free time as it is. The ability to make their own decisions on how to spend their time is a learning experience, too.
