The Neuroscience of Your Brain on Fiction - NYTimes.com - 6 views

  • The brain, it seems, does not make much of a distinction between reading about an experience and encountering it in real life; in each case, the same neurological regions are stimulated. Keith Oatley, an emeritus professor of cognitive psychology at the University of Toronto (and a published novelist), has proposed that reading produces a vivid simulation of reality, one that “runs on minds of readers just as computer simulations run on computers.” Fiction — with its redolent details, imaginative metaphors and attentive descriptions of people and their actions — offers an especially rich replica. Indeed, in one respect novels go beyond simulating reality to give readers an experience unavailable off the page: the opportunity to enter fully into other people’s thoughts and feelings.

    Science is supporting the idea of descriptive, narrative passages as providing different brain stimulation from simply nonfiction or informative reading.

Memory - Wikipedia, the free encyclopedia - 0 views

  • Encoding of working memory involves the spiking of individual neurons induced by sensory input, which persists even after the sensory input disappears (Jensen and Lisman 2005; Fransen et al. 2002). Encoding of episodic memory involves persistent changes in molecular structures that alter synaptic transmission between neurons. Examples of such structural changes include long-term potentiation (LTP) or spike-timing-dependent plasticity (STDP). The persistent spiking in working memory can enhance the synaptic and cellular changes in the encoding of episodic memory (Jensen and Lisman 2005).
  • Recent functional imaging studies detected working memory signals in both medial temporal lobe (MTL), a brain area strongly associated with long-term memory, and prefrontal cortex (Ranganath et al. 2005), suggesting a strong relationship between working memory and long-term memory. However, the substantially more working memory signals seen in the prefrontal lobe suggest that this area play a more important role in working memory than MTL (Suzuki 2007).
  • Consolidation and reconsolidation. Short-term memory (STM) is temporary and subject to disruption, while long-term memory (LTM), once consolidated, is persistent and stable. Consolidation of STM into LTM at the molecular level presumably involves two processes: synaptic consolidation and system consolidation. The former involves a protein synthesis process in the medial temporal lobe (MTL), whereas the latter transforms the MTL-dependent memory into an MTL-independent memory over months to years (Ledoux 2007). In recent years, such traditional consolidation dogma has been re-evaluated as a result of the studies on reconsolidation. These studies showed that prevention after retrieval affects subsequent retrieval of the memory (Sara 2000). New studies have shown that post-retrieval treatment with protein synthesis inhibitors and many other compounds can lead to an amnestic state (Nadel et al. 2000b; Alberini 2005; Dudai 2006). These findings on reconsolidation fit with the behavioral evidence that retrieved memory is not a carbon copy of the initial experiences, and memories are updated during retrieval.

  • Physical exercise, particularly continuous aerobic exercises such as running, cycling and swimming, has many cognitive benefits and effects on the brain. Influences on the brain include increases in neurotransmitter levels, improved oxygen and nutrient delivery, and increased neurogenesis in the hippocampus. The effects of exercise on memory have important implications for improving children's academic performance, maintaining mental abilities in old age, and the prevention and potential cure of neurological diseases.
  • At the Center for Cognitive Science at Ohio State University, researchers have found that memory accuracy of adults is hurt by the fact that they know more, and have more experience than children, and tend to apply all this knowledge when learning new information. The findings appeared in the August 2004 edition of the journal Psychological Science.
  • Interference can hamper memorization and retrieval. There is retroactive interference, when learning new information makes it harder to recall old information[59] and proactive interference, where prior learning disrupts recall of new information. Although interference can lead to forgetting, it is important to keep in mind that there are situations when old information can facilitate learning of new information. Knowing Latin, for instance, can help an individual learn a related language such as French – this phenomenon is known as positive transfer.[60]
  • Methods to optimize memorization[edit] Memorization is a method of learning that allows an individual to recall information verbatim. Rote learning is the method most often used. Methods of memorizing things have been the subject of much discussion over the years with some writers, such as Cosmos Rossellius using visual alphabets. The spacing effect shows that an individual is more likely to remember a list of items when rehearsal is spaced over an extended period of time. In contrast to this is cramming which is intensive memorization in a short period of time. Also relevant is the Zeigarnik effect which states that people remember uncompleted or interrupted tasks better than completed ones. The so-called Method of loci uses spatial memory to memorize non-spatial information.[72]

Font Size May Not Aid Learning, but Its Style Can, Researchers Find - NYTimes.com - 110 views

  • Is it easier to remember a new fact if it appears in normal type, like this, or in big, bold letters, like this?
  • Font size has no effect on memory, even though most people assume that bigger is better. But font style does.
  • New research finds that people retain significantly more material — whether science, history or language — when they study it in a font that is not only unfamiliar but also hard to read.
  • ...6 more annotations...
  • “So much of the learning that we do now is unsupervised, on our own,” said Robert A. Bjork, a psychologist at the University of California, Los Angeles, “that it’s crucial to be able to monitor that learning accurately; that is, to know how well we know what we know, so that we avoid fooling ourselves.”
  • “Studying something in the presence of an answer, whether it’s conscious or not, influences how you interpret the question,” Dr. Bjork said. “You don’t appreciate all of the other things that would have come to mind if the answer weren’t there. “Let’s say you’re studying capitals and you see that Australia’s is Canberra. O.K., that seems easy enough. But when the exam question appears, you think: ‘Uh oh, was it Sydney? Melbourne? Adelaide?’ ” That’s why some experts are leery of students’ increasing use of online sites like Cramster, Course Hero, Koofers and others that offer summaries, step-by-step problem solving and copies of previous exams. The extra help may provide a valuable supplement to a difficult or crowded course, but it could also leave students with a false sense of mastery. Even course outlines provided by a teacher, a textbook or other outside source can create a false sense of security, some research suggests. In one experiment, researchers found that participants studying a difficult chapter on the industrial uses of microbes remembered more when they were given a poor outline — which they had to rework to match the material — than a more accurate one.
  • a cognitive quality known as fluency, a measure of how easy a piece of information is to process.
  • On real tests, font size made no difference and practice paid off, the study found.
  • And so it goes, researchers say, with most study sessions: difficulty builds mental muscle, while ease often builds only confidence.
  • To test the approach in the classroom, the researchers conducted a large experiment involving 222 students at a public school in Chesterland, Ohio. One group had all its supplementary study materials, in English, history and science courses, reset in an unusual font, like Monotype Corsiva. The others studied as before. After the lessons were completed, the researchers evaluated the classes’ relevant tests and found that those students who’d been squinting at the stranger typefaces did significantly better than the others in all the classes — particularly in physics. “The reason that the unusual fonts are effective is that it causes us to think more deeply about the material,” a co-author of the study, Daniel M. Oppenheimer, a psychologist at Princeton, wrote in an e-mail. “But we are capable of thinking deeply without being subjected to unusual fonts. Think of it this way, you can’t skim material in a hard to read font, so putting text in a hard-to-read font will force you to read more carefully.” Then again, so will raw effort, he and other researchers said. Concentrating harder. Making outlines from scratch. Working through problem sets without glancing at the answers. And studying with classmates who test one another.

Educational Leadership:Teaching for the 21st Century:21st Century Skills: The Challenge... - 119 views

  • the skills students need in the 21st century are not new.
  • Critical thinking and problem solving, for example, have been components of human progress throughout history
  • What's actually new is the extent to which changes in our economy and the world mean that collective and individual success depends on having such skills
  • ...27 more annotations...
  • Many reform efforts, from reducing class size to improving reading instruction, have devolved into fads or been implemented with weak fidelity to their core intent. The 21st century skills movement faces the same risk.
  • some of the rhetoric we have heard surrounding this movement suggests that with so much new knowledge being created, content no longer matters; that ways of knowing information are now much more important than information itself. Such notions contradict what we know about teaching and learning and raise concerns that the 21st century skills movement will end up being a weak intervention for the very students—low-income students and students of color—who most need powerful schools as a matter of social equity.
  • First, educators and policymakers must ensure that the instructional program is complete and that content is not shortchanged for an ephemeral pursuit of skills
  • Second, states, school districts, and schools need to revamp how they think about human capital in education—in particular how teachers are trained
  • inally, we need new assessments that can accurately measure richer learning and more complex tasks
  • Skills and knowledge are not separate, however, but intertwined.
  • In some cases, knowledge helps us recognize the underlying structure of a problem.
  • At other times, we know that we have a particular thinking skill, but domain knowledge is necessary if we are to use it.
  • if skills are independent of content, we could reasonably conclude that we can develop these skills through the use of any content. For example, if students can learn how to think critically about science in the context of any scientific material, a teacher should select content that will engage students (for instance, the chemistry of candy), even if that content is not central to the field. But all content is not equally important to mathematics, or to science, or to literature. To think critically, students need the knowledge that is central to the domain.
  • The importance of content in the development of thinking creates several challenges
  • first is the temptation to emphasize advanced, conceptual thinking too early in training
  • Another curricular challenge is that we don't yet know how to teach self-direction, collaboration, creativity, and innovation the way we know how to teach long division.
  • But experience is not the same thing as practice. Experience means only that you use a skill; practice means that you try to improve by noticing what you are doing wrong and formulating strategies to do better. Practice also requires feedback, usually from someone more skilled than you are.
  • We must plan to teach skills in the context of particular content knowledge and to treat both as equally important.
  • education leaders must be realistic about which skills are teachable. If we deem that such skills as collaboration and self-direction are essential, we should launch a concerted effort to study how they can be taught effectively rather than blithely assume that mandating their teaching will result in students learning them.
  • teachers don't use them.
  • Even when class sizes are reduced, teachers do not change their teaching strategies or use these student-centered method
  • these methods pose classroom management problems for teachers.
  • These methods also demand that teachers be knowledgeable about a broad range of topics and are prepared to make in-the-moment decisions as the lesson plan progresses.
  • constant juggling act
  • greater collaboration among teachers.
  • But where will schools find the release time for such collaboration?
  • professional development is a massive undertaking.
  • Unfortunately, there is a widespread belief that teachers already know how to do this if only we could unleash them from today's stifling standards and accountability metrics. This notion romanticizes student-centered methods, underestimates the challenge of implementing such methods, and ignores the lack of capacity in the field today.
  • The first challenge is the cost.
  • measures that encourage greater creativity, show how students arrived at answers, and even allow for collaboration.
  • When students first encounter new ideas, their knowledge is shallow and their understanding is bound to specific examples. They need exposure to varied examples before their understanding of a concept becomes more abstract and they can successfully apply that understanding to novel situations.

Analytical research questions effectiveness of Mindset as an educational intervention - 19 views

  •  
    "A major research publication recently released in the journal "Psychological Science" has called into question the notion of mindsets in academic achievement outcomes. The theory holds that individuals with growth mindsets (beliefs that attributes are malleable with effort) enjoy many positive outcomes-including higher academic achievement-while their peers who have fixed mindsets experience negative outcomes."

What Should Schools Teach? 10 suggestions by @RichardJARogers - 23 views

    "I'm one of those few people who can actually say that I use the stuff I was taught in school on daily basis in my job. I'm a Science Teacher: so naturally, I'm teaching my students almost the same things I was taught at school. However, there are a lot of things I had to work out by myself when I left school. Was 'personal experience' the best way to learn these things?"

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
    • Brian C. Smith
       
      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.
  • those who diligently practice creative activities learn to recruit their brains’ creative networks quicker and better
    • Ed Webb
       
      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.

  • 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.”
