Statistics of homework

Too much homework may diminish its effectiveness. While research on the optimum amount of time students should spend on homework is limited, there are indications that for high school students, 1½ to 2½ hours per night is optimum. Middle school students appear to benefit from smaller amounts (less than 1 hour per night).

While many agree that homework does have a time and place, there needs to be a balance between life and school. There also needs to be communication with other teachers in the school about assignments. Oftentimes, educators get so involved in their subject area, they communicate departmentally, not school-wide.

The research. The most comprehensive research on homework to date comes from a 2006 meta-analysis by Duke University psychology professor Harris Cooper, who found evidence of a positive correlation between homework and student achievement, meaning students who did homework performed better in school.

They also interviewed students about their views on homework. When it came to stress, more than 70 percent of students said they were “often or always stressed over schoolwork,” with 56 percent listing homework as a primary stressor. Less than 1 percent of the students said homework was not a stressor.
