Re-reading is inefficient. Here are 8 tips for studying smarter. • ©[vox.com]

We know from surveys that a majority of students, when they study, they typically re-read assignments and notes. Most students say this is their number one go-to strategy.

We know, however, from a lot of research, that this kind of repetitive recycling of information is not an especially good way to learn or create more permanent memories. Our studies of Washington University students, for instance, show that when they re-read a textbook chapter, they have absolutely no improvement in learning over those who just read it once.

On your first reading of something, you extract a lot of understanding. But when you do the second reading, you read with a sense of ‘I know this, I know this.’ So basically, you’re not processing it deeply, or picking more out of it. Often, the re-reading is cursory — and it’s insidious, because this gives you the illusion that you know the material very well, when in fact there are gaps.”

The Push-Button School of Tomorrow (1958) • ©[paleofuture.com]

The May 5, 1958 edition of Arthur Radebaugh’s Sunday comic, Closer Than We Think, showed off the high-tech school of tomorrow. With hordes of baby boomers flooding into public schools in the 1950s, it makes sense that this strip would focus on different solutions for overcrowding with that technological optimism we identify as being uniquely post-war American.

The student desk of the future includes a small camera, presumably so that the teacher being projected on a large screen in the front of the class can keep tabs on the little rascals. One thing that fascinates me about computer consoles of the retrofuture is that the QWERTY keyboard is not yet an assumed input device.

We need open models, not just open data - O'Reilly Radar

… if you’re not careful, modelling has a nasty way of enshrining prejudice with a veneer of “science” and “math.”Cathy has consistently made another point that’s a corollary of her argument about enshrining prejudice. At O’Reilly, we talk a lot about open data. But it’s not just the data that has to be open: it’s also the models. (There are too many must-read articles on Cathy’s blog to link to; you’ll have to find the rest on your own.)

You can have all the crime data you want, all the real estate data you want, all the student performance data you want, all the medical data you want, but if you don’t know what models are being used to generate results, you don’t have much.

UK needs an ethics council and digital chief in every department – tech experts | Technology | The Guardian

The UK government should establish an expert technology ethics body to help address complex challenges, including health monitoring, autonomous vehicles and legal disputes such as the right to be forgotten, an independent review has recommended.

The ethical body, which would be similar to those in medicine and academia, is just one of a slate of wide-ranging recommendations in the Making Digital Government Work for Everyone review published on Tuesday, which explores how technology and digital services could be better used to help citizens.

Commissioned by Labour and written by an independent panel of more than 20 advisers and volunteers, the review has been in progress since December 2013.

Peter Gray’s new book says kids need free play to thrive – ©[bc.edu]

Playing with other children, away from adults, is how children learn to make their own decisions, control their emotions and impulses, see from others’ perspectives, negotiate differences with others, and make friends,” says Gray, an expert on the evolution of play and its vital role in child development. “In short, play is how children learn to take control of their lives.”

All children are born with an innate curiosity, playfulness, sociability and deep desire to learn, but at some point after they enter school, what was once fun and engaging begins to feel forced, he explains. And, anxiety and stress levels among youths are at an all-time high: they are bogged down with homework, over-scheduled with extracurricular activities, deprived of free play, and faced with the pressures of getting into a top college.

Ubiquitous, light, easy to operate, it’s, it’s … | Omniprésent, léger, facile à utiliser, c’est, c’est … | plerudulier

I can’t believe that over the years I have maintained this blog I haven’t written once about TiddlyWiki. In a nutshell it’s a non linear personal web notebook… which doesn’t mean much to many I suppose. There’s no point copying and pasting here descriptions of what it does there, right ? Makes more sense to explain what it does for me and how I use it.

5 Countries That Do It Better: How Sexual Prudery Makes America a Less Healthy and Happy Place | [alternet.org]

To extreme social conservatives of the far right, the word “prude” is not an insult — it’s a badge of honor. “Prudes,” they would argue, should be upheld as exemplary role models because a sexually repressive society is also a society with fewer unplanned pregnancies and fewer sexually transmitted diseases. But not only do the facts not bear that out, they also demonstrate that the exact opposite is true. Countries that embrace many of the things social conservatives detest comprehensive sex education, pro-gay legislation, nude or topless beaches, legal or decriminalized prostitution, adult entertainment tend to be countries that have less sexual dysfunction than the United States, not more. And when one compares sexual attitudes in the United States to sexual attitudes in Western Europe, it becomes evident that there is a strong correlation between social conservatism and higher rates of teen pregnancy, abortion and sexually transmitted diseases.
