The Creativity Crisis - Newsweek - 48 views

  • there is one crucial difference between IQ and CQ scores. With intelligence, there is a phenomenon called the Flynn effect—each generation, scores go up about 10 points. Enriched environments are making kids smarter. With creativity, a reverse trend has just been identified and is being reported for the first time here: American creativity scores are falling.
  • “Creativity can be taught,”
  • it’s left to the luck of the draw who becomes creative: there’s no concerted effort to nurture the creativity of all children

      Students are labeled as "creative" if they display a knack for art or music, and sometimes in writing, however, they are rarely recognized as creative in math or science where a lot of creativity is not only needed, but excellent for learning within those very two disciplines.
    • Bill Genereux
       
      This is precisely why creativity education is important. It is needed everywhere, not just in the arts. Those teaching outside of arts education need to start recognizing the importance of creative thinking as well.

  • When faculty of a major Chinese university asked Plucker to identify trends in American education, he described our focus on standardized curriculum, rote memorization, and nationalized testing. “After my answer was translated, they just started laughing out loud,” Plucker says. “They said, ‘You’re racing toward our old model. But we’re racing toward your model, as fast as we can.’ ”
  • The argument that we can’t teach creativity because kids already have too much to learn is a false trade-off. Creativity isn’t about freedom from concrete facts. Rather, fact-finding and deep research are vital stages in the creative process.
  • When you try to solve a problem, you begin by concentrating on obvious facts and familiar solutions, to see if the answer lies there. This is a mostly left-brain stage of attack. If the answer doesn’t come, the right and left hemispheres of the brain activate together. Neural networks on the right side scan remote memories that could be vaguely relevant. A wide range of distant information that is normally tuned out becomes available to the left hemisphere, which searches for unseen patterns, alternative meanings, and high-level abstractions. Having glimpsed such a connection, the left brain must quickly lock in on it before it escapes. The attention system must radically reverse gears, going from defocused attention to extremely focused attention. In a flash, the brain pulls together these disparate shreds of thought and binds them into a new single idea that enters consciousness. This is the “aha!” moment of insight, often followed by a spark of pleasure as the brain recognizes the novelty of what it’s come up with. Now the brain must evaluate the idea it just generated. Is it worth pursuing? Creativity requires constant shifting, blender pulses of both divergent thinking and convergent thinking, to combine new information with old and forgotten ideas. Highly creative people are very good at marshaling their brains into bilateral mode, and the more creative they are, the more they dual-activate.

      Surely, "more quickly"?
  • Creativity has always been prized in American society, but it’s never really been understood. While our creativity scores decline unchecked, the current national strategy for creativity consists of little more than praying for a Greek muse to drop by our houses. The problems we face now, and in the future, simply demand that we do more than just hope for inspiration to strike. Fortunately, the science can help: we know the steps to lead that elusive muse right to our doors.

      Likely because it was out of necessity and the hardships of life. Not that we don't have hardships and necessities, but innovation has solved a lot of problems and automation has made skills and tasks easy.
  • What’s common about successful programs is they alternate maximum divergent thinking with bouts of intense convergent thinking, through several stages. Real improvement doesn’t happen in a weekend workshop. But when applied to the everyday process of work or school, brain function improves.

      Everyday process of work or school... over time, consistent and non-prescriptive.
  • kids demonstrated the very definition of creativity: alternating between divergent and convergent thinking, they arrived at original and useful ideas. And they’d unwittingly mastered Ohio’s required fifth-grade curriculum—from understanding sound waves to per-unit cost calculations to the art of persuasive writing. “You never see our kids saying, ‘I’ll never use this so I don’t need to learn it,’ ” says school administrator Maryann Wolowiec. “Instead, kids ask, ‘Do we have to leave school now?’ ” Two weeks ago, when the school received its results on the state’s achievement test, principal Traci Buckner was moved to tears. The raw scores indicate that, in its first year, the school has already become one of the top three schools in Akron, despite having open enrollment by lottery and 42 percent of its students living in poverty.
  • project-based learning
  • highly creative adults frequently grew up with hardship. Hardship by itself doesn’t lead to creativity, but it does force kids to become more flexible—and flexibility helps with creativity.
  • When creative children have a supportive teacher—someone tolerant of unconventional answers, occasional disruptions, or detours of curiosity—they tend to excel. When they don’t, they tend to underperform and drop out of high school or don’t finish college at high rates. They’re quitting because they’re discouraged and bored, not because they’re dark, depressed, anxious, or neurotic. It’s a myth that creative people have these traits. (Those traits actually shut down creativity; they make people less open to experience and less interested in novelty.) Rather, creative people, for the most part, exhibit active moods and positive affect. They’re not particularly happy—contentment is a kind of complacency creative people rarely have. But they’re engaged, motivated, and open to the world.
  • solutions emerge from a healthy marketplace of ideas, sustained by a populace constantly contributing original ideas and receptive to the ideas of others
  • The age-old belief that the arts have a special claim to creativity is unfounded.
  • When scholars gave creativity tasks to both engineering majors and music majors, their scores laid down on an identical spectrum, with the same high averages and standard deviations. Inside their brains, the same thing was happening—ideas were being generated and evaluated on the fly.
  • The lore of pop psychology is that creativity occurs on the right side of the brain. But we now know that if you tried to be creative using only the right side of your brain, it’d be like living with ideas perpetually at the tip of your tongue, just beyond reach
  • those who diligently practice creative activities learn to recruit their brains’ creative networks quicker and better. A lifetime of consistent habits gradually changes the neurological pattern.
  • The home-game version of this means no longer encouraging kids to spring straight ahead to the right answer
  • The new view is that creativity is part of normal brain function.
  • “As a child, I never had an identity as a ‘creative person,’ ” Schwarzrock recalls. “But now that I know, it helps explain a lot of what I felt and went through.”
  • In China there has been widespread education reform to extinguish the drill-and-kill teaching style. Instead, Chinese schools are also adopting a problem-based learning approach.

How I reverse-engineered Google Docs to play back any document's keystrokes «... - 70 views

  •  
    This person has created a site that show how a document was created - letter by letter, deletion by deletion! Whilst this might be tedious, used appropriately it might show the editing process clearly. You can do an analysis of keystrokes - when and how many.You can highlight text and show how it changed over time. Man, there are some clever people out there!

Demography and the Future of Secularism - Boston.com - 1 views

    • Steven Young
       
      The American Enterprise Institute is one of the leading conservative think tanks. The AEI, and the conservative movement in general, have an interest in a more religious population, since religious voters are more likely to vote Republican and for conservative parties elsewhere in the world. Therefore, one needs to skeptical of research emanating from a think tank with a strong ideological bias; especially when that research serves the interests of the institution.
  • Across the world, "population change is reversing secularism and shifting the center of gravity of entire societies in a conservative religious direction." The same will be true here in the United States, where religious families have more children than non-religious ones.
  • It's easy to underestimate the role that population change can have in social change, Kaufmann says, but it can have a huge role, especially when differences in values drive differences in fertility

  • the fringe of ultra-Orthodox pupils in Israel's Jewish primary schools in 1960 has ballooned: they now comprise a third of the Jewish first grade class. They are gaining power: in Jerusalem, Haredim rioted in late December, demanding the right to segregate women on buses, and have already elected the city's first Haredi mayor.
  • the ultra-Orthodox may form a majority of observant American and British Jews by 2050
  • In the United States, Republicans have a similar values-driven fertility advantage -- an advantage, Kaufmann argues, which will outweigh the Democratic advantage of increased immigration, in part because many immigrants are conservative on social issues and maximalist in their family planning.

Startup turns carbon dioxide into fuels - 1 views

  • Today, carbon dioxide (CO2) is a hot topic. Scientists around the globe are searching for ways to store, dispose of, or prevent the formation of the greenhouse gas, which is a major driver of global climate change. Liquid Light hopes to take this concept one step further and harness waste CO2 as a source of carbon to make industrial chemicals and fuels.
  • Take CO2 and mix it in a water-filled chamber with an electrode and a catalyst. The ensuing chemical reaction converts CO2 into a new molecule, methanol, which can be used as a fuel, an industrial solvent or a starting material for the manufacture of other chemicals.
  • Bocarsly likes to call the process "reverse combustion" because it is like running a burning reaction backwards. Instead of burning fuel and oxygen to produce CO2, the CO2 converts back into fuel and oxygen.

  • Cole set up a flask containing a solution of CO2 and a pyridinium catalyst dissolved in water. In place of sunlight, which emits a broad spectrum of wavelengths of light, she shined on the flask a blue light-emitting diode (LED) because it gives off certain wavelengths that are highly efficient at driving the reaction. In the flask she placed an electrode that is activated by particles of light, or photons. "We used a semiconductor electrode that would allow us to substitute light for electricity," said Cole.
  • The Princeton scientists did some additional studies, and made a surprising discovery: They could turn CO2, which contains only one carbon, into a compound with a carbon-carbon bond, which vastly increases the possibilities for creating commercial applications.

      Nice job coming back to Freeman. I would like to have seen more of this back-and-forth between the authors.
  • Mark Fenton expressed in the article “Battling America’s Epidemic of Physical Inactivity: Building More Walkable, Livable Communities” many different things we can do to help the obesity problem in America. Fenton states, “We must create environments in which physical activity becomes a routine part of the day for more Americans.” By creating a more pedestrian friendly atmosphere it will encourage people to walk or bicycle to their destination instead of always using their automobiles. I agree with what Fenton is trying to explain within in his research. Children learn by the examples that are being set around them. If they see everyone driving in their cars every where they go the only thing they have in their heads is, “I can’t wait until i can drive.” Instead of realizing they can go the same exact distance on their bike and be much more healthy than if they were driving a car. Fenton expresses, “We all must become role models by walking and cycling whenever possible and inviting others to do so with us.” People don’t like feeling abnormal; they want to do what other people are doing around them. Which is a very true assumption on Fentons part, we must become the role models for the youth around us. We set the standards of what is acceptable and what isn’t. We need to change the “norms” while it’s still possible and contribute to reversing the obesity problem

      Great job here dealing with your source material. You quote, come-to-terms, reflect on the material you've introduced, and offer your own position. Then you come back to another quote by Fenton, and do much of the same. Excellent!
