... with too many students, more each year, and ridiculous amounts of homework assigned, so much that there's no way a teacher can even look at it all (on your own time at night) much less evaluate it, ...
There is at least a solution to that one, stop assigning homework. It has no positive effects before middle school that anyone has been able to find.
Are we wasting our children's time by giving them more homework?
Ozkan Erena, Daniel J. Henderson
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.
