 Children's Attention Spans are Short, and Education Deman...

The 2016 paper, “Off-task behavior in elementary school children,” was published in the peer-reviewed journal Learning and Instruction, and was funded by the Institute of Education Sciences, an arm of the Department of Education. The researchers also kept track of how the teachers were instructing students during these observations. Not surprisingly, students went off task more frequently during whole-group instruction than during small group or individual work. Length of lesson matters...

 African Americans are the Descendants of Alien Abductees

Dery identified the parallels in "Black to the Future" as 'African Americans are, in a very real sense, the descendanmt of alien abductees," Dery writes. He compares the atrocities of racism experienced by blacks in the United States to "a sci-fi nightmare in which unseen but no less impassable force fields intolerance frustrate their movement; official histories undo what has been done; and technology is too often brought to bear on black bodies (branding, forced sterilization, the Tuskegee ...

 Gamification Card Drafting Mechanic

Mrs. Lee creates five decks of cards to structure her assessment—each deck has two cards more than the total number of students (to increase variability). The cards in Deck 1 have the name of a 20th century poet who was not the subject of an in-class discussion. The cards in Deck 2 each feature a poetic theme (e.g., love, death). The cards in Deck 3 stipulate a poetic technique (e.g., assonance, metaphor). The cards in Deck 4 feature a form of creative expression (e.g., write a song, write ...

 Opportunities in Education Technology

Opportunity 1: Improving Mastery of Academic Skills Create apps to teach academic skills in more meaningful ways than traditional textbooks and lectures. Give learners an opportunity to practice in realistic settings. This might be done through interactive simulations (e.g., models of ancient cities that allow students to experience history or virtual chemistry simulations that might be unsafe to reproduce in a classroom). Think beyond delivering content—are there tools that enable student...

 Essays Should Not Need to Argue a Point

The Age of the Essay September 2004 Remember the essays you had to write in high school? Topic sentence, introductory paragraph, supporting paragraphs, conclusion. The conclusion being, say, that Ahab in Moby Dick was a Christ-like figure. Oy. So I'm going to try to give the other side of the story: what an essay really is, and how you write one. Or at least, how I write one. Mods The most obvious difference between real essays and the things one has to write in school is that real ess...

 Far-Right Rhetoric is Profitable

Representative Tom Cole, an Oklahoman in the House Republican leadership and a former politics professor, said, “There’s a big difference between intellectual conservatism and what exists out there now. It’s much more populist in its orientation and much wider in its reach. This is not an elite opinion, a Bill Buckley sort of thing.” And in a nod to the new media’s greater profitability, Cole added, “While it’s conservative in its orientation, it’s a financially driven enterpr...

 China to Rate Online Behaviour in Social Credit System

Chinese internet firms are definitely interested, as Ant Financial, a subsidiary of ecommercegiant Alibaba, recently showed. To its popular app Alipay it added a new service which rated a person's credit worthiness on a scale of 350 to 950 points. This score is not only determined by one's lending behavior, but also by hobbies and friends. If friends have a poor lending reputation, this reflects badly on the person, just as prolonged playing of video games. Buying diapers indicates responsibi...

 Scientist on Trial for Teaching Physics

After waiting patiently for the noise to subside, one of the male Red Guards turned to the victim. “Ye Zhetai, you are an expert in mechanics. You should see how strong the great unified force you’re resisting is. To remain so stubborn will lead only to your death! Today, we will continue the agenda from the last time. There’s no need to waste words. Answer the following question without your typical deceit: Between the years of 1962 and 1965, did you not decide on your own to add relat...

 The One-Electron Universe

I received a telephone call one day at the graduate college at Princeton from Professor Wheeler, in which he said, "Feynman, I know why all electrons have the same charge and the same mass" "Why?" "Because, they are all the same electron!" And, then he explained on the telephone, "suppose that the world lines which we were ordinarily considering before in time and space - instead of only going up in time were a tremendous knot, and then, when we cut through the knot, by the pl...

 How Poverty Affects IQ

In a series of experiments, the researchers found that pressing financial concerns had an immediate impact on the ability of low-income individuals to perform on common cognitive and logic tests. On average, a person preoccupied with money problems exhibited a drop in cognitive function similar to a 13-point dip in IQ, or the loss of an entire night's sleep. But when their concerns were benign, low-income individuals performed competently, at a similar level to people who were well off, said...

Fascinating for the fact that IQ appears so plastic in just day-to-day environment. Removing the stressors increases the IQ.
