8 math talks to blow your mind Mathematics gets down to work in these talks, breathing life and logic into everyday problems. Prepare for math puzzlers both solved and unsolvable, and even some still waiting for solutions. Ron Eglash: The fractals at the heart of African designs When Ron Eglash first saw an aerial photo of an African village, he couldn’t rest until he knew — were the fractals in the layout of the village a coincidence, or were the forces of mathematics and culture colliding in unexpected ways? Here, he tells of his travels around the continent in search of an answer. How big is infinity? Arthur Benjamin does “Mathemagic” A whole team of calculators is no match for Arthur Benjamin, as he does astounding mental math in the blink of an eye.

We need to talk about TED | Benjamin Bratton In our culture, talking about the future is sometimes a polite way of saying things about the present that would otherwise be rude or risky. But have you ever wondered why so little of the future promised in TED talks actually happens? So much potential and enthusiasm, and so little actual change. I write about entanglements of technology and culture, how technologies enable the making of certain worlds, and at the same time how culture structures how those technologies will evolve, this way or that. So my TED talk is not about my work or my new book – the usual spiel – but about TED itself, what it is and why it doesn't work. The first reason is over-simplification. At this point I kind of lost it. So I ask the question: does TED epitomize a situation where if a scientist's work (or an artist's or philosopher's or activist's or whoever) is told that their work is not worthy of support, because the public doesn't feel good listening to them? What is TED? So what is TED exactly? Such as…
Why Learning Through Social Networks Is The Future by Paul Moss, edmerger.com Students Need Professional Learning Networks, Too Learning to create, manage and promote a professional learning network (PLN) will soon become, if it’s not already, one of the most necessary and sought after skills for a global citizen, and as such, must become a prominent feature of any school curriculum. Few progressive educationalists would argue that a personal learning network (PLN) is not incredibly valuable and important. However presently, few discussions and promotions of PLN’s venture further than lauding specific benefits for teachers. Establishing a PLN seems simple enough on the surface, but to do it successfully and optimize its potential contains within in it a challenging and vigorous set of learning opportunities. 1. To curate or not to curate – that is actually not the question. The trend is irrefutable (Rosenbaum), and can facilitate reaching political disruption as Twitter founder Evan Williams notes. 2. 3.

Marjorie Hansen Shaevitz: What College Admissions Offices Look for in Extracurricular Activities Admissions officers look first at test scores, the rigor of the courses you take, and your grades in those courses. After that, they are interested in a student’s extracurricular activities — in other words, how you spend your time outside of classes. Colleges care about the character of people they admit; therefore, what you do after school, during weekends and over summers tells them a lot about the kind of person you are. When you think about it, you are what you do every day, every month, every year. When it comes to extracurricular involvements, it doesn’t really matter what the content is. Anything from doing a major DNA research project to volunteering at a school that serves low income students to excelling at fly-fishing is legitimate fodder for college application grids. Extracurricular activities are the major way students can demonstrate how unique they are, possibly more interesting, even “better” than other student applicants, and showcase what they love to do.

How the Mind Works: 10 Fascinating TED Talks How memory works, what visual illusions reveal, the price of happiness, the power of introverts and more… 1. Peter Doolittle: How “working memory” works “Life comes at us very quickly, and what we need to do is take that amorphous flow of experience and somehow extract meaning from it.” In this funny, enlightening talk, educational psychologist Peter Doolittle details the importance — and limitations — of your “working memory,” that part of the brain that allows us to make sense of what’s happening right now.” 2. “What motivates us to work? Behavioral economist Dan Ariely presents two eye-opening experiments that reveal our unexpected and nuanced attitudes toward meaning in our work.” 3. “Why do people see the Virgin Mary on a cheese sandwich or hear demonic lyrics in “Stairway to Heaven”? Using video and music, skeptic Michael Shermer shows how we convince ourselves to believe — and overlook the facts.” 4. 5. 6. “Can happiness be bought? 7. 8. 9. 10.
The trouble with TED talks I’ve long been amused by the slogan of TED, makers of the ubiquitous TED talks. TED’s slogan is this: ‘Ideas worth spreading.’ Apparently TED has some ideas, and we should spread them. What ideas? Ideas that TED in its infinite wisdom has picked out for us, ideas which are therefore implied to be true and good and right. What should we do with these ideas? It’s nearing midnight, and I’m sitting in my pants in front of the computer holding a tumbler of scotch, the curtains closed, the lights off, doing something I don’t do enough of these days – just watching. I start with a talk by Rob Legato, and sixteen minutes later I’m aware of only three things: the talk was awesome, I can’t remember anything of substance from the talk, and I’m now watching a weirdly artificial standing ovation - by sheer coincidence a camera happens to be pointed at some of the first audience members to rise to their feet; then the rest of the audience follows, compelled by social instinct to follow their peers.
Petite histoire de la formation à distance – infographie Quand on parle de formation à distance, on pense immédiatement à l’e-learning et à Internet. Mais en réalité, la formation à distance a déjà une très longue histoire derrière elle, vieille de près de 3 siècles. Voici une infographie et un article pour revoir un peu cette petite histoire de la formation à distance. Avertissement : cette infographie et l’article qui l’accompagne sont extraits d’une ressource du cours « Apprendre en ligne » que je me prépare à lancer dans les prochaines semaines. Ce cours sera offert à l’inscription de tout autre cours en ligne que je proposerai bientôt. Mise à jour 7-02-2014 : MOOC ITyPA. La formation à distance : une histoire vieille de près de trois siècles ! L’engouement récent pour les MOOCs (cours en ligne massif et ouverts) et pour l’e-learning en général nous font oublier à quel point l’histoire de la formation à distance est déjà riche et ancienne.
