An interesting summary of Stanislas Dehaene’s research in our numbers sense that has implications for how we teach math: The fundamental problem with learning mathematics is that while the number sense may be genetic, exact calculation requires cultural tools—symbols and algorithms—that have been around for only a few thousand years and must therefore be absorbed by areas of the brain that evolved for other purposes.
Now, where did I put the internet?

The quest for Netflix’s prize to whomever creates a movie-recommending algorithm 10 percent better than its own reveals some interesting ideas about what constitutes a better algorithm. Rogue contestant Gavin Potter: The 20th century was about sorting out supply. The 21st is going to be about sorting out demand.
Hence, demand is characterized by finely tuned algorithms and human behaviourial economics theories.
We are wired to find meaning in the world, and emotional stress and events of personal significance push us strongly toward magical meaning-making. We incorporate superstition and other explanations into our world view. Susan Gelman explains it this way: God puts you in the path of an HIV-positive lover, but biology causes you to contract the virus from his semen.
Is Web 2.0 democracy a myth? Is it more a case of wisdom of the chaperones than wisdom of the crowds? Chris Wilson concludes, Digg and Wikipedia would do well to stop pretending they’re operated by the many and start thinking of ways to rein in the power of the few.
Sarah Boxer on blog writing as id writing: …I think I get the superhero fixation. It’s the flying. It’s the suspension of punctuation and good manners and even identity. Bloggers at their computers are Supermen in flight. They break the rules. They go into their virtual phone booths, put on their costumes, bring down their personal villains, and save the world. Anonymous or not, they inhabit that source of power and hope. Then they come back to their jobs, their dogs, and their lives, and it’s like, ‘Dude, the ball.’
Where does a blog post go? Wired magazines’ flash animation follows a blog post as it makes its way from mere post to reader via the Interweb: The Life Cycle of a Blog Post, from servers to spiders to suits to you [flash animation].
We can now download Lawrence Lessig’s The Future of Ideas [pdf] for free. Lessig, a professor of law at Stanford Law School and vocal critic of the extension of the copyright term in United States, persuaded Random House to release the book under a Creative Commons license.
Increasingly, celebrities are taking an active interest in political causes. Are they actually making a difference? No doubt that celebrities can raise the profile of issues near and dear to their hearts. But highlighting a problem is not the same thing as solving it—on that score, the celebrity track record at affecting policy outcomes is the same as the rest of us: mixed.
Is disdain for Céline Dion innate or learned? Is our love or hatred of My Heart Will Go On the result of a universal, disinterested instinct for beauty-assessment? Or is it something less exalted? Carl Wilson tends to side with the French sociologist Pierre Bourdieu, who argues that taste is never disinterested: It’s a form of social currency, or “cultural capital,†that we use to stockpile prestige. Hating Céline is therefore not just an aesthetic choice, but an ethical one, a way to elevate yourself above her fans—who, according to market research, tend to be disproportionately poor adult women living in flyover states and shopping at big-box stores.
This photo of 11-year old child bride sitting next to her 40-year old fiance captures a small, everyday moment that wouldn’t surprise anyone in the Taliban. But to Western eyes it is quite a different matter. Dutch writer Leon de Winter: Our eyes behold an abomination. Our eyes have learned to see the world from the perspective of a slowly acquired sense for humanity. And although more and more voices tell us that we — the former colonialists and imperialists — have lost the right to judge other cultures, we know just as well as this girl that this marriage is wrong.
David Byrne’s describes 6 music distribution models, each offering various levels of artistic control. The totally DIY model is certainly not for everyone — but that’s the point. Now there’s choice.
What I like about this piece is how David Byrnes defines music, and that by doing so expands the idea that it is just a piece of plastic meant to be bought, sold, traded and replayed endlessly in any context. We’ll always want to use music as part of our social fabric: to congregate at concerts and in bars, even if the sound sucks; to pass music from hand to hand (or via the Internet) as a form of social currency; to build temples where only “our kind of people” can hear music (opera houses and symphony halls); to want to know more about our favorite bards — their love lives, their clothes, their political beliefs.
We are reading less as we age, and we are reading less than people who were our age ten or twenty years ago. Caleb Crain reacts to The National Endowment of the Arts (N.E.A.) recent report on American reading patterns that connects declines in reading with civic, social, and economic implications and asks what society might be like if only a few elite people read literary texts as a hobby.
Heard the one about using only 10% of our brains? Not true. Doctors pour cold water on this and 6 other medical myths in the British Medical Journal. These myths were based on ideas the authors had heard endorsed on several occasions, and which many physicians thought were true. But after we carefully lay out medical evidence, they are very willing to accept that these beliefs are actually false.
Cass Sunstein argues that the ability to filter information on the internet is going to lead to a world of fractured communications, group polarizations, cascades of false information, finally resulting in a rise in extremism. It’s a relief to hear arguments that do not see the internet as an ideal force for democracy, but his argument relies on “perfect filtering,” without any explanation for how this is even possible.
Doris Lessing has been a lifelong advocate from freedom, democracy and human decency. So it is a little disheartening that in her acceptance speech for the Nobel Prize for Literature she has not interpreted some of the big cultural changes in the context of technology, such as diversity, lifelong learning, participation and citizenship.
Communities of Practice
The idea that learning requires a deepening process of participation in a community of practice has gained increased recognition in the recent years. Communities of practice have also become an important area within organizational development.
Designing SOPs for Learners
Are you writing SOPs your staff can understand? This poster, presented at the AABB 2007 conference, offers evidence-based principles for designing standard operating procedures that support learning. You can also visit us at The SOP Designers’ Club for more resources and information.
