Boys tend to fall behind in homework, even though their test scores are comparable, because they are less likely to be organized. They are less likely to do homework. In fact, homework completion, and actually turning it in, is one of the biggest causes in what we call the gender gap, in terms of the kids' GPA. Girls are 70 percent of the A's and boys are in 70 percent of the D's and F's. All of that can be narrowed down into homework completion, not doing what they need to do in class. Boys are less inclined to want to do it to please the teacher. If a boy doesn't see relevancy in it, don't see why this matters to them, why they should have to do it, if the task is somewhat menial perhaps. If they find it really annoying to do, like if there's 70 problems to do instead of maybe 25; and it gets to be too much busy work, boys are more likely to say, "You know what? This is dumb. I'm not doing it." Girls are more likely to do it. When they turn it in, they get the better grades. Boys and girls can be equally as smart, but have very different outcomes in terms of their grades.
