What we know about out-of-school time

Measuring the relationship between out-of-school time and outcomes like test scores can be difficult. Researchers are primarily confounded by an inability to determine what compels students to choose homework during their time off over other activities. Are those who spend more time on homework just extra motivated? Or are they struggling students who need to work harder to keep up? What role do social expectations from parents or peers play?
Previous studies have examined the impact of this outside time use on educational outcomes for students. A 2007 study using data from Berea College in Kentucky identified a causal relationship between hours spent studying and a student’s academic performance through an interesting measure. The researchers took advantage of randomly assigned college roommates, paying attention to those who came to campus with a video game console in tow. They hypothesized students randomly assigned to a roommate without a video game console would study more, since all other factors remained equal. That hypothesis held up, and that group also received significantly higher grades, demonstrating the causal relationship.
