Homework Always Improves Achievement

The belief that homework universally improves academic achievement is not supported by current research. A comprehensive review of homework studies conducted between 1987 and 2003 by Duke University researcher Harris Cooper found that for elementary school students (K-6), there was no measurable academic benefit from homework. For middle school students, the benefits were only modest. While homework can serve various purposes, simply assigning more of it does not automatically translate to better learning outcomes, particularly for younger students. In fact, an excessive amount of homework can sometimes lead to decreased engagement, potentially undermining its intended educational purpose. This suggests a need for a balanced and purposeful approach to homework assignments, with Cooper's research suggesting about 10 minutes of homework per night for each grade level.
