Creativity is rejected: Teachers and bosses don't value out-of-the-box thinking. - 47 views

  • This is the thing about creativity that is rarely acknowledged: Most people don’t actually like it. Studies confirm what many creative people have suspected all along: People are biased against creative thinking, despite all of their insistence otherwise.
  • Staw says most people are risk-averse. He refers to them as satisfiers.
  • Satisfiers avoid stirring things up, even if it means forsaking the truth or rejecting a good idea.
  • ...8 more annotations...
  • Uncertainty is an inherent part of new ideas, and it’s also something that most people would do almost anything to avoid. People’s partiality toward certainty biases them against creative ideas and can interfere with their ability to even recognize creative ideas.
  • Unfortunately, the place where our first creative ideas go to die is the place that should be most open to them—school. Studies show that teachers overwhelmingly discriminate against creative students, favoring their satisfier classmates who more readily follow directions and do what they’re told.
  • It’s ironic that even as children are taught the accomplishments of the world’s most innovative minds, their own creativity is being squelched.
  • All of this negativity isn’t easy to digest, and social rejection can be painful in some of the same ways physical pain hurts. But there is a glimmer of hope in all of this rejection. A Cornell study makes the case that social rejection is not actually bad for the creative process—and can even facilitate it.
  • Truly creative ideas take a very long time to be accepted. The better the idea, the longer it might take.
  • Most people agree that what distinguishes those who become famously creative is their resilience. While creativity at times is very rewarding, it is not about happiness. Staw says a successful creative person is someone “who can survive conformity pressures and be impervious to social pressure.”
  • To live creatively is a choice.
  • You have to let go of satisfying people, often even yourself.
  •  
    We say we like creativity, but we really don't. Thoughtful post on the resistance to creative thinking.

A veteran teacher turned coach shadows 2 students for 2 days - a sobering lesson learne... - 56 views

  • But students move almost never. And never is exhausting.
    • Sharin Tebo
       
      This was no different in my experience. There was not one class where I was asked to move to work with someone else. However, there was opportunity for engagement with others, where the teacher let the students do the talking and the working. 
  • sitting passively.
    • Sharin Tebo
       
      Passive engagement is how I would describe most students to 'sat and got' while the teacher spoke. However, this was not the case in 100% of classes I shadowed/participated in.
  • build in a hands-on, move-around activity into every single class day. Yes, we would sacrifice some content to do this – that’s fine.
    • Sharin Tebo
       
      We typically do this in a language learning class, so it was tiresome for me to not have the opportunity to move around and engage with others.

  • High School students are sitting passively and listening during approximately 90% of their classes.
  • It was not just the sitting that was draining but that so much of the day was spent absorbing information but not often grappling with it.
    • Sharin Tebo
       
      This was not true for all my classes today when I shadowed. The teacher in one class served as a model to annotate an article while we did the same. We were left to our own devices to write the main idea in 2-3 sentences, too. We also had to sum up our learning by analyzing topics in some pretty tough questions in Physics, and the final question was to put it all together and list a real-world example. I thought this was clever.
    • deniseahlquist
       
      Early in my career, I also was asked to shadow students (when we were choosing schools for a funded project) and it was definitely one of the most eye-opening experiences I've had. I could not believe how resentful and angry I felt at the end of the day and I think of myself as someone who just loves to learn, but I did so little of it in most of the classes. After the experience, I was no longer surprised that students struggle to stay focused, and I redoubled my efforts to help support teaching and learning experiences that actively engage learners in building understanding. Highly recommend this experience for any teacher, coach or administrator.
  • If I could go back and change my classes now, I would immediately: Offer brief, blitzkrieg-like mini-lessons with engaging, assessment-for-learning-type activities
  • set an egg timer every time I get up to talk and all eyes are on me. When the timer goes off, I am done.
  • Ask every class to start with students’ Essential Questions or just general questions born of confusion from the previous night’s reading or the previous class’s discussion.
    • Sharin Tebo
       
      This was listed on the board in one class, but it was not discussed. 
  • Teachers work hard
    • Sharin Tebo
       
      Yes, they do work hard, but is it productive and best for student learning to be doing everything while students are passive? Why not make the kids do the heavy lifting so it is best for them?

Method of loci - Wikipedia, the free encyclopedia - 0 views

  • The Method of Loci (plural of Latin locus for place or location), also called the memory palace, is a mnemonic device introduced in ancient Roman and Greek rhetorical treatises (in the anonymous Rhetorica ad Herennium, Cicero's De Oratore, and Quintilian's Institutio oratoria). The items to be remembered in this mnemonic system are mentally associated with specific physical locations.[1] It relies on memorized spatial relationships to establish, order and recollect memorial content. The term is most often found in specialised works on psychology, neurobiology and memory, though it was used in the same general way at least as early as the first half of the nineteenth century in works on rhetoric, logic and philosophy.[2]

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]

A Peek Into the Future: What College Will Be Like in 10 Years - WSJ.com - 51 views

  • online classes that let students learn at their own pace, drawing on materials from schools across the country—not just a single professor and a hefty textbook.

  • s new technologies seep into the classroom, it will be easier to measure what students actually learn. That will "make universities more accountable for what they produce," Dr. Crow says.
  • The Classroom In the near future, professors will run their courses over digital platforms capable of collecting data on each student's progress. These platforms were initially developed for massive open online courses, or MOOCs. However, universities are now folding these platforms back into their traditional classes because they make it easier to share content, host discussions and keep track of student work. A professor might still "teach" a class, but most of the interaction will happen online.If professors and students do meet in a physical classroom, it will be to review material, work through problems or drill down on discussion topics. Scenes like John Houseman lecturing to an auditorium full of students in "The Paper Chase" will be a thing of the past.

Are students afforded opportunities to evaluate their progress regularly? Are students encouraged to pose questions regularly in class? Are students provided with guides to help them reflect on their thinking (such as Bloom’s Taxonomy)? Do class projects engage students in analysis, synthesis, and evaluation? Are students given opportunities to consider various opinions and to justify their own beliefs?

Books Have Many Futures : NPR - 18 views

  • Long the building blocks of academia, textbooks are seen more as albatross and less as asset these days. They are expensive — some costing more than $300. They are quickly outdated. They can be so heavy that students and teachers are forced to tote them around in wheeled luggage carts. Students, professors and universities are rebelling against the weighty — and wasteful — tomes. Stanford University's brand new physics and engineering library is advertised as "bookless"; relying almost solely on digital material. Free and downloadable textbooks are at the heart of the growing "open educational resources" movement that seeks to make education more available and more affordable. Groups such as Connexions at Rice University and the Community College Consortium for Open Educational Resources in Silicon Valley are supporting free online textbook initiatives.
