Too much homework. (How does one feel after just reading those words?) Researchers from the Stanford grad school of Education, Lewis and Clark College and Villanova University conducted a study in high schoolers living in high-income, high-achieving communities and located that spending an excessive amount of time on homework could have negative effects on students' health and well-being.
The researchers engaged with 4,317 participants in 10 California high schools through surveys and interviews. Students had a mean of three .1 hours of homework each night. As Stanford News reports, the study cites earlier work that found 90 minutes to two-and-a-half hours of nightly homework to be optimal for top schoolers.
