The Anthropic Principle

As an example of the power of the Anthropic Principle, consider the number of directions in space. It is a matter of common experience that we live in three-dimensional space. That is to say, we can represent the position of a point in space by three numbers. For example, latitude. longitude and height above sea level. But why is space three-dimensional? Why isn't it two, or four, or some other number of dimensions, hke in science fiction? In fact, in M-theory space has ten dimensions (as wel...

 Emotional Contagions in Social Networks

These results highlight several features of emotional contagion. First, because News Feed content is not “directed” toward anyone, contagion could not be just the result of some specific interaction with a happy or sad partner. Although prior research examined whether an emotion can be contracted via a direct interaction (1, 7), we show that simply failing to “overhear” a friend’s emotional expression via Facebook is enough to buffer one from its effects. Second, although nonverbal ...

 Use of an Umpire to Hide Troop Movements in a War Game

Three maps should be provided, either in separate rooms or separated from each other by screens: one for each player, and one in the centre for the Umpire.* Each Commander and his subordinates will be allowed access only to their own map, the Umpire and his assistants moving from one side to the other. [...] Whenever any portion of OIK; of the opposing forces comes within the view of the other, the corresponding blocks of the former must be placed on the map of the latter and rice ver...

 Just-In-Time Learning

Teachers should create situations where the students are required to locate the facts and information specifically related to the context of the question at hand, and then to utilize that information effectively. An example is the Jasper Mathematics series created by the Vanderbilt University's Peabody College of Education. In these multimedia presentations, students are introduced to characters that are faced with a mathematical dilemma that the students help the characters solve. Rather tha...

 Game-Based VS Gamified

Broadly speaking, those who advocate for game-based education seek to find ways to integrate specific, preexisting games directly into the curriculum. They want to use games to illustrate specific points or develop specific skills that they believe are uniquely developed by the game in question (Prensky, 2001). There are many fine games that could be incorporated into a host of curricula that would help students learn more and develop more sophisticated skills, and they can be played as is ou...

 A User Interface Can Change the Way We Think

In extreme cases, to use such an interface is to enter a new world, containing objects and actions unlike any you've previously seen. At first these elements seem strange. But as they become familiar, you internalize the elements of this world. Eventually, you become fluent, discovering powerful and surprising idioms, emergent patterns hidden within the interface. You begin to think with the interface, learning patterns of thought that would formerly have seemed strange, but which become seco...

 You were never actually accomplishing anything by watchin...

If you ask someone what they accomplish by watching the news, you’ll hear vague notions like, “It’s our civic duty to stay informed!” or “I need to know what’s going on in the world,” or “We can’t just ignore these issues,” none of which answer the question. “Being informed” sounds like an accomplishment, but it implies that any information will do. You can become informed by reading a bus schedule. A month after you’ve quit the news, it’s hard to name anything u...

 Most current-events-related conversations are just people...

“Because it helps you participate in everyday conversations!” is a weak but at least meaningful answer to the “What is accomplished” question. But when you quit playing the current events game, and observe others talking about them, you might notice that almost nobody really knows what they’re talking about. There is an extraordinary gulf between having a functional understanding of an issue, and the cursory glance you get from the news. If you ever come across a water-cooler conve...

 Use Cards to Call on Students

When I realized that I was unintentionally disengaging from some students, I developed a classroom management practice that ensures equal participation and on-the-fly formative assessments. I use a deck of playing cards, each of which is marked with a student's name, to determine who will answer the next question. The deck randomizes participation and shows my students that I am not subjectively skipping them or "picking on" someone. The deck is the arbiter and it contributes to an engaged cl...

 Essay Writing is About Figuring Things Out

To understand what a real essay is, we have to reach back into history again, though this time not so far. To Michel de Montaigne, who in 1580 published a book of what he called "essais." He was doing something quite different from what lawyers do, and the difference is embodied in the name. Essayer is the French verb meaning "to try" and an essai is an attempt. An essay is something you write to try to figure something out. Figure out what? You don't know yet. And so you can't begin with a ...
