The comments on this article are sad. I am a kid and I know homework is a necessity. The studies proving that there is a positive correlation between homework and achievements is overwhelming. People need to stop hating homework and start working on it especially when it is helping THEM. As for people who can't find time to do homework due to sports and other activities, make time. Doing well in school is more important than sports. You can exercise any time you want and the chances of getting into a college due to a sports scholarship is very low. Better to focus on your educacion.
The last, and most common, way of measuring achievement is to use standardized test scores. Purely because they’re standardized, these tests are widely regarded as objective instruments for assessing children’s academic performance. But as I’ve argued elsewhere at some length, there is considerable reason to believe that standardized tests are a poor measure of intellectual proficiency. They are, however, excellent indicators of two things. The first is affluence: Up to 90 percent of the difference in scores among schools, communities, or even states can be accounted for, statistically speaking, without knowing anything about what happened inside the classrooms. All you need are some facts about the average income and education levels of the students’ parents. The second phenomenon that standardized tests measure is how skillful a particular group of students is at taking standardized tests – and, increasingly, how much class time has been given over to preparing them to do just that.
6. Even the title of their article reflects this: They ask “When Is Homework Worth the Time?” rather than “ Is Homework Worth the Time?” This bias might seem a bit surprising in the case of the study’s second author, Robert H. Tai. He had contributed earlier to another study whose results similarly ended up raising questions about the value of homework. Students enrolled in college physics courses were surveyed to determine whether any features of their high school physics courses were now of use to them. At first a very small relationship was found between the amount of homework that students had had in high school and how well they were currently faring. But once the researchers controlled for other variables, such as the type of classes they had taken, that relationship disappeared, just as it had for Keith (see note 2). The researchers then studied a much larger population of students in college science classes – and found the same thing: Homework simply didn’t help. See Philip M. Sadler and Robert H. Tai, “Success in Introductory College Physics: The Role of High School Preparation,” Science Education 85 : 111-36.
