Now You See It: How the Brain Science of Attention Will Transform the Way We Live, Work... - 5 views

  •  
    Davidson (formerly a vice provost at Duke and now codirector of the HASTAC/MacArthur Foundation Digital and Media Learning Competitions) argues our current assessment methods are conditioned by the needs and values of the industrial revolution. Teachers grade students the same way the USDA grades beef. Asks how we might overcome "attention blindness" to gain broader perspective on mental and physical surroundings.

Gove unveils Tory plan for return to 'traditional' school lessons - Times Online - 22 views

  • a committee of the “greatest minds in Britain” would decide what children were taught. The Prince of Wales’ Teaching Institute would also be involved in drawing up a new curriculum.
  • “I’m an unashamed traditionalist when it comes to the curriculum,” Mr Gove said. “Most parents would rather their children had a traditional education, with children sitting in rows, learning the kings and queens of England, the great works of literature, proper mental arithmetic, algebra by the age of 11, modern foreign languages. That’s the best training of the mind and that’s how children will be able to compete.”
    • Ed Webb
       
      The best training of the mind?! Is he high?
  • “The invitation is there for all the great minds of our time to help reshape the national curriculum — both primary and secondary,” Mr Gove said. “We want to rewrite the whole thing and we are going to start as soon as we get in. We need the experts to tell us what is needed. The critical thing is to find people who want the intellectual life of the nation to be revived.”
    • Ed Webb

  • He’s absolutely right in saying that what draws people into teaching is that they love history or physics, and they want to communicate that love. They don’t love abstract thinking skills; they love the thrill of discovery in their own special field.
    • Ed Webb
       
      I love teaching. Come ask me.
  • “I was amazed to discover that science is not divided into physics, chemistry and biology. It has these hybrid headings about the chemical and material whatever and the Earth, the environment and this and that.”
    • Ed Webb
       
      Because, you know, hybridity is evil - EVIL! Interdisciplinary, inquiry-driven education is clearly a plot to weaken the moral fibre of the nation. Any increase in actual learning or interest on the part of students that it may produce must be an aberration.
  • Lessons should celebrate rather than denigrate Britain’s role through the ages, including the Empire. “Guilt about Britain’s past is misplaced.”
    • Ed Webb
       
      Has Mr Gove been reading Niall Ferguson? Or maybe taking lessons from recent French policy? Either way, bizarre and frightening.
  • I’ve been talking to the RSC about bringing Shakespeare into primary schools
    • Ed Webb
       
      More state funding for Shakespeare in schools I could get behind
  • Modern languages will also be revived. “One of the biggest tragedies in state education over the last ten years has been this huge drop in French and German, Italian and Spanish,”
    • Ed Webb
       
      More languages - good. But surely Chinese and Arabic should be high on the list? And Farsi, Urdu, Hindi, Russian...

iOS Apps for Science Teachers : Teaching about Sound - 3 views

  •  
    "Teaching about sound in the classroom used to involve lots of fiddly bits of kit such as Signal Generators and Decibel Meters that would cost a lot of money and only get wheeled out once a year. Thankfully if you have an iPhone or iPad you can replace quite a bit of that kit with a couple of handy apps which are either free or relatively inexpensive. Here's a couple to get you started:"

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]

    I disliked this video. Is my classroom extraordinary? The rest of the classrooms in the U.S. have unmoving, silent children stuck in desks all day? The students don't talk to each other? They don't collaborate to solve problems? They don't read? They don't write in order to analyze and express opinions? They don't use math manipulatives, do science experiments, build, draw, and do projects? They don't laugh together, digress, and then get back on track? Because that's what we do. It doesn't strike me as a response to the Industrial Revolution as much as a response to students' curiosity and to their future needs. "If we get it right, kids won't even know they're learning something." So, we're doing it wrong if the kids are actually aware that they're learning? Better they should be metaphorically anesthetized by the computer experience? We don't want them inoculated against feeling the discomfort of struggle. Every respected neuroscientist on the planet says struggle is necessary to wire neurons together, which is the physical manifestation of learning. The simulation of the village looks very cool. I love computers. But if all their learning about ancient Rome is based on this simulation, where are the primary sources? Will students encounter any? Or is their experience of the village based on someone else's interpretation of primary sources? If so, then someone else gets to decide what is important to include in the Roman village. They get to choose and interpret the facts that are used to create the virtual ancient Roman experience. That goes against best practice teaching of the social sciences.

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.

    Students' raw effort improves learning [No surprise there, huh?]
