Homework; an unnecessary evil

Your kids will love this research, but don’t expect many changes in the school system in the near future.

From the Washington Post

And the result of this fine-tuned investigation? There was no relationship whatsoever between time spent on homework and course grade, and “no substantive difference in grades between students who complete homework and those who do not.”

This result clearly caught the researchers off-guard. Frankly, it surprised me, too. When you measure “achievement” in terms of grades, you expect to see a positive result — not because homework is academically beneficial but because the same teacher who gives the assignments evaluates the students who complete them, and the final grade is often based at least partly on whether, and to what extent, students did the homework. Even if homework were a complete waste of time, how could it not be positively related to course grades?

And yet it wasn’t. Again. Even in high school. Even in math. The study zeroed in on specific course grades, which represents a methodological improvement, and the moral may be: The better the research, the less likely one is to find any benefits from homework.
