RICHMOND, Va — Researchers reached a conclusion that many parents may have heard first from their teenage students: a new study found too much homework can actually be a bad thing. The American Psychological Association published a study looking at 8,000 teenage students. Researchers found the students did the best when teachers assigned homework regularly, and about an hour of it a night.
After 70 minutes of homework, though, the standardized test results began to drop off, indicating a decrease in the benefit.
Scientists also found students benefited the most from homework when they completed it independently, without getting help from their parents.
