Does Homework Matter?

IZA DP No. 5547

Ozkan Eren, Daniel J. Henderson:

Are We Wasting Our Children's Time by Giving Them More Homework?

(forthcoming in: Economics of Education Review)

Following an identification strategy that allows us to largely eliminate unobserved student and teacher traits, we examine the effect of homework on math, science, English and history test scores for eighth grade students in the United States. Noting that failure to control for these effects yields selection biases on the estimated effect of homework, we find that math homework has a large and statistically meaningful effect on math test scores throughout our sample. However, additional homework in science, English and history are shown to have little to no impact on their respective test scores.

Very interesting Mark. Just remember, this doesn't apply to post-graduate students.

I love the idea of some kid in first year secondary school presented his teacher with detailed IV evidence that homework does not have a causal effect on outcomes.
