The Truth About Homework

The Truth About Homework
September 6, 2006 The Truth About Homework Needless Assignments Persist Because of Widespread Misconceptions About Learning By Alfie Kohn Para leer este artículo en Español, haga clic aquí. There’s something perversely fascinating about educational policies that are clearly at odds with the available data. The dimensions of that last disparity weren’t clear to me until I began sifting through the research for a new book. In high school, some studies do find a correlation between homework and test scores (or grades), but it’s usually fairly small and it has a tendency to disappear when more sophisticated statistical controls are applied. The results of national and international exams raise further doubts. Finally, there isn’t a shred of evidence to support the widely accepted assumption that homework yields nonacademic benefits for students of any age. Sandra Hofferth of the University of Maryland, one of the authors of that study, has just released an update based on 2002 data.

An Essay by Einstein -- The World As I See It "How strange is the lot of us mortals! Each of us is here for a brief sojourn; for what purpose he knows not, though he sometimes thinks he senses it. But without deeper reflection one knows from daily life that one exists for other people -- first of all for those upon whose smiles and well-being our own happiness is wholly dependent, and then for the many, unknown to us, to whose destinies we are bound by the ties of sympathy. A hundred times every day I remind myself that my inner and outer life are based on the labors of other men, living and dead, and that I must exert myself in order to give in the same measure as I have received and am still receiving... "I have never looked upon ease and happiness as ends in themselves -- this critical basis I call the ideal of a pigsty. "My passionate sense of social justice and social responsibility has always contrasted oddly with my pronounced lack of need for direct contact with other human beings and human communities.

Playground Interactive activities, some used other places on Serendip for other reasons, and others just because ...? The idea, of course, is that there isn't a whole lot of difference between playing and learning ... exploring is the underpinnings and enjoyment inherent in both. If that idea makes you think of either play or education in new ways, so much the better. Regardless, the web provides not only information and pictures, but also the wherewithal to have experiences that you might not otherwise have a chance to have. And creating such things to play with (and maybe even to learn from) is a large part of what Serendip is about, so browse the list. And have fun. If in addition you'd like to read/think more about play itself, there's a list of relevant links below.

Free will? Ambiguous figures, of which the Serendip logo (circa 1994-95) is one example, make possible some interesting observations bearing on the existence and meaning of "free will". In most people's minds, "free will" has two relatively distinct properties. The first is the idea that what one does is in some sense "free", that is "not determined by something else". The second is the idea that one can onself control what one does. Notice that the Serendip logo can sometimes be seen as consisting of green arrows pointing to the right, and at other times as yellow arrows pointing to the left, but is infrequently or never seen as both (unless one tries very hard). Whether one sees right of left pointing arrows most easily can be influenced by details of the constuction of the figure (colors, exact shapes, and so forth), previous experiences with other figures, stable personal preferences, and mood. An additional observation implies that, in this situation, you can control what you do.

7 Common Habits That Secretly Make You Anxious Do you know why so many people have trouble dealing with anxiety? Simply put, it boils down to a lack of perspective. Most of us think of anxiety as something that’s irrevocably… out there; as though it were an ominous and invisible threat plotting against our well-being. All too frequently, people conceive of anxiety as an external factor they cannot possibly control. You may not be aware of it, but there are common habits of the mind and body that you constantly indulge, which secretly add up to your anxiety. Coffee: Often regarded as a harmless beverage, coffee is actually a highly additive anxiety-inducing drug; it makes people more alert, but it also makes them jittery and nervous.
