BBC News - Neutrino experiment repeat at Cern finds same result - 33 views
-
The KC about neutrinos travelling faster than the speed of light has been tested by conducting the experiment in a different way to rule out methodological knowledge issues. The result was the same. Thus the KC has not been falsified at the first hurdle. Failure to falsify does not make a KC true, but each time it survives it gets a little stronger in our minds.

Girls need more positive experiences of ball skills - 3 views
-
"Children's positive perception of moving is an important supporter for natural physical activity and developing motor skills. A study at the University of Jyväskylä suggests that children had high perceptions of motor skills. Some gender differences were identified, however: girls were better in locomotor skills and boys had higher perception and actual skills in ball skills. "Because ball skills are typically utilized in versatile surroundings and good ball skills are a predictor for more frequent physical activity levels in adolescence, we should encourage girls to play more with balls already in early education," says PhD student Donna Niemistö from Faculty of Sport and Health Sciences. "In boys, there could be more locomotor skills like galloping and hopping involved. Niemistö concludes, "All children regardless of gender have a right to have positive and encouraging experiences of movement.""

Because of these preferences—and because getting away from multipurpose screens improves concentration—people consistently say that when they really want to dive into a text, they read it on paper

This is backed up by a recent article: Faris, Michael J., and Stuart A. Selber. "E-Book Issues In Composition: A Partial Assessment And Perspective For Teachers." Composition Forum 24.(2011): ERIC. Web. 31 Mar. 2013.

Although many old and recent studies conclude that people understand what they read on paper more thoroughly than what they read on screens, the differences are often small. Some experiments, however, suggest that researchers should look not just at immediate reading comprehension, but also at long-term memory.

When taking the quiz, volunteers who had read study material on a monitor relied much more on remembering than on knowing, whereas students who read on paper depended equally on remembering and knowing.

Subconsciously, many people may think of reading on a computer or tablet as a less serious affair than reading on paper. Based on a detailed 2005 survey of 113 people in northern California, Ziming Liu of San Jose State University concluded that people reading on screens take a lot of shortcuts—they spend more time browsing, scanning and hunting for keywords compared with people reading on paper, and are more likely to read a document once, and only once.

About - Institute of Making - 28 views
-
The Institute of Making is a multidisciplinary research club for those interested in the made world: from makers of molecules to makers of buildings, synthetic skin to spacecraft, soup to diamonds, socks to cities. Annual membership of the institute is available to all UCL staff and students. Our programme of symposia, masterclasses and public events explores the links between academic research and hands-on experience, and celebrates the sheer joy of stuff. Its mission is to provide all makers with a creative home in which to innovate, contemplate and understand all aspects of materials and an inspiring place to explore their relationship to making. At the heart of the Institute of Making is the Materials Library - a growing repository of some of the most extraordinary materials on earth, gathered together for their ability to fire the imagination and advance conceptualisation. A place in which makers from all disciplines can see, touch, research and discuss, so that they can apply the knowledge and experience gained to their own practice. Alongside the collection is the MakeSpace - a workshop where members and guests can make, break, design and combine both advanced and traditional tools, techniques and materials."

“The freshman year [as taught at traditional schools] should not exist,” Nelson says, suggesting that MOOCs can teach the basics. “Do your freshman year at home.”) Instead, Minerva’s first-year classes are designed to inculcate what Nelson calls “habits of mind” and “foundational concepts,” which are the basis for all sound systematic thought. In a science class, for example, students should develop a deep understanding of the need for controlled experiments. In a humanities class, they need to learn the classical techniques of rhetoric and develop basic persuasive skills. The curriculum then builds from that foundation.

So why are students relegated to lectures when it’s proven that active learning can significantly enhance the educational experience?
-
Simple. They don't have instructional beliefs that they all agree upon. These teachers work as independent contractors, and take any criticism of their practice personally. But they forget that it is not about them. It's about the students. -
I think that you have forgot to include a lack of professional development (training) to demonstrate successful educational strategies. Telling someone (a teacher) they must change is just like a lecture. Showing them how they can change their practice to make a difference is needed as well.

The Reading Brain in the Digital Age: The Science of Paper versus Screens - Scientific ... - 25 views
-
The matter is by no means settled. Before 1992 most studies concluded that people read slower, less accurately and less comprehensively on screens than on paper. Studies published since the early 1990s, however, have produced more inconsistent results: a slight majority has confirmed earlier conclusions, but almost as many have found few significant differences in reading speed or comprehension between paper and screens. And recent surveys suggest that although most people still prefer paper—especially when reading intensively—attitudes are changing as tablets and e-reading technology improve and reading digital books for facts and fun becomes more common.
-
Compared with paper, screens may also drain more of our mental resources while we are reading and make it a little harder to remember what we read when we are done. A parallel line of research focuses on people's attitudes toward different kinds of media. Whether they realize it or not, many people approach computers and tablets with a state of mind less conducive to learning than the one they bring to paper.
-
Both anecdotally and in published studies, people report that when trying to locate a particular piece of written information they often remember where in the text it appeared. We might recall that we passed the red farmhouse near the start of the trail before we started climbing uphill through the forest; in a similar way, we remember that we read about Mr. Darcy rebuffing Elizabeth Bennett on the bottom of the left-hand page in one of the earlier chapters.

-
At least a few studies suggest that by limiting the way people navigate texts, screens impair comprehension.
-
Because of their easy navigability, paper books and documents may be better suited to absorption in a text. "The ease with which you can find out the beginning, end and everything inbetween and the constant connection to your path, your progress in the text, might be some way of making it less taxing cognitively, so you have more free capacity for comprehension," Mangen says.
-
An e-reader always weighs the same, regardless of whether you are reading Proust's magnum opus or one of Hemingway's short stories. Some researchers have found that these discrepancies create enough "haptic dissonance" to dissuade some people from using e-readers. People expect books to look, feel and even smell a certain way; when they do not, reading sometimes becomes less enjoyable or even unpleasant. For others, the convenience of a slim portable e-reader outweighs any attachment they might have to the feel of paper books.
-
In one of his experiments 72 volunteers completed the Higher Education Entrance Examination READ test—a 30-minute, Swedish-language reading-comprehension exam consisting of multiple-choice questions about five texts averaging 1,000 words each. People who took the test on a computer scored lower and reported higher levels of stress and tiredness than people who completed it on paper.
-
Perhaps, then, any discrepancies in reading comprehension between paper and screens will shrink as people's attitudes continue to change. The star of "A Magazine Is an iPad That Does Not Work" is three-and-a-half years old today and no longer interacts with paper magazines as though they were touchscreens, her father says. Perhaps she and her peers will grow up without the subtle bias against screens that seems to lurk in the minds of older generations. In current research for Microsoft, Sellen has learned that many people do not feel much ownership of e-books because of their impermanence and intangibility: "They think of using an e-book, not owning an e-book," she says. Participants in her studies say that when they really like an electronic book, they go out and get the paper version. This reminds Sellen of people's early opinions of digital music, which she has also studied. Despite initial resistance, people love curating, organizing and sharing digital music today. Attitudes toward e-books may transition in a similar way, especially if e-readers and tablets allow more sharing and social interaction than they currently do.
