There's a kernel of truth behind that one, FWIW. A growing body of evidence indicates that there can be too much of a good thing: Past a certain point, more homework actually hinders learning rather than helping it. By way of analogy, it's not at all unlike how most weightlifting advice says to give your muscles a day of rest in between workout sessions. e.g., I recently watched a talk where a researcher cited a study that found that putting kids in remedial literacy programs, with all their drilling and whatnot, seems to do more harm than good. The (deliberately over-simplified) impression I got was that, if you leave the kids alone instead of bothering them, you'll generally see a markedly bigger improvement through simple regression to the mean. That this gets over-simiplified into a simple "homework bad" in the popular sphere is unfortunate. Sadly, nobody has yet figured out a way to inoculate science so that it can survive on Facebook.
