    Author describes study that showed that middle, hs, and university students were highly distractible by technology and were anxious if they could not check their devices. He described a strategy called "tech breaks" where students are allowed to check devices and social media for a minute and then to focus on school work for 15 minutes as a way of improving their metacognitive skills.

    I wonder if using technology in the classroom - integrally - would mitigate some of the anxiety and/or increase attention. I wonder if there are other teaching/learning strategies we might employ that would increase engagement such that students would be distracted from their distraction...

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 think this is the essence of teaching and learning - asking questions, for nothing is really true.

  • Constructivist learning environments provide multiple representations of reality
  • Multiple representations avoid oversimplification and represent the complexity of the real world
  • Constructivist learning environments emphasize authentic tasks in a meaningful context rather than abstract instruction out of context.
  • Constructivist learning environments provide learning environments such as real-world settings or case-based learnin
  • Constructivist learning environments encourage thoughtful reflection on experience.
  • Constructivist learning environments support "collaborative construction of knowledge through social negotiation, not competition among learners for recognition.
  • Jonassen (1994)
  • There is no absolute knowledge, just our interpretation of it. The acquisition of knowledge therefore requires the individual to consider the information and - based on their past experiences, personal views, and cultural background - construct an interpretation of the information that is being presented to them.
  • Teaching styles based on this approach therefore mark a conscious effort to move from these ‘traditional, objectivist models didactic, memory-oriented transmission models’ (Cannella & Reiff, 1994) to a more student-centred approach.
  • Students ‘construct’ their own meaning by building on their previous knowledge and experience. New ideas and experiences are matched against existing knowledge, and the learner constructs new or adapted rules to make sense of the world
  • John Dewey (1933/1998) is often cited as the philosophical founder of this approach
  • while Vygotsky (1978) is the major theorist among the social constructivists.
  • Bruner (1990) and Piaget (1972) are considered the chief theorists among the cogn
  • Dewey
  • Piaget
  • John Dewey rejected the notion that schools should focus on repetitive, rote memorization & proposed a method of "directed living" – students would engage in real-world, practical workshops in which they would demonstrate their knowledge through creativity and collaboration
  • Piaget rejected the idea that learning was the passive assimilation of given knowledge. Instead, he proposed that learning is a dynamic process comprising successive stages of adaption to reality during which learners actively construct knowledge by creating and testing their own theories of the world.
  • A common misunderstanding regarding constructivism is that instructors should never tell students anything directly but, instead, should always allow them to construct knowledge for themselves. This is actually confusing a theory of pedagogy (teaching) with a theory of knowing. Constructivism assumes that all knowledge is constructed from the learner’s previous knowledge, regardless of how one is taught. Thus, even listening to a lecture involves active attempts to construct new knowledge.
  • social interaction lay at the root of good learning.
  • Bruner builds on the Socratic tradition of learning through dialogue, encouraging the learner to come to enlighten themselves through reflection
  • Careful curriculum design is essential so that one area builds upon the other. Learning must therefore be a process of discovery where learners build their own knowledge, with the active dialogue of teachers, building on their existing knowledge.
  • Social constructivism was developed by Vygotsky. He rejected the assumption made by Piaget that it was possible to separate learning from its social context.

      On Vgotsky`s side here - I don`t think you can forget the role of "social learning", peer to peer learning and the role of social interaction.
  • The basic tenet of constructivism is that students learn by doing rather than observing.
  • By the 1980s the research of Dewey and Vygotsky had blended with Piaget's work in developmental psychology into the broad approach of constructivism
  • 1. Discovery Learning (Bruner) In discovery learning, the student is placed in problem solving situations where they are required to draw on past experiences and existing knowledge to discover facts, relationships, and new information. Students are more likely to retain knowledge attained by engaging real-world and contextualised problem-solving than by traditional transmission methods. Models that are based upon discovery learning model include: guided discovery, problem-based learning, simulation-based learning, case-based learning, and incidental learning.

  • Mixbook (or Mixbook for Educators) is a photo-based creation platform that offers hundreds of layouts and backgrounds to choose from along with customizable frames and text to make your book beautiful. Just pick a layout, drag-and-drop your photos into the photo slots, and edit to your heart's content.
  • Though the site's examples suggest using the books to gather wedding, travel, and baby albums, this program can absolutely used to create stories around historic photographs and artifacts, original art, to produce a class yearbook, to share an oral or personal history or journey, to tell the story of a field trip.  Mixbook for Educators now offers a secure collaborative environment for sharing their ebooks, as well as discounts on printed products, should you choose to print.  (A similar option is Scrapblog.)
  • Storybird, a collaborative storybook building space designed for ages 3-13, inspires young writers to create text around the work of professional artists and the collection of art is growing. Two (or more) people create a Storybird in a round robin fashion by writing their own text and inserting pictures. They then have the option of sharing their Storybird privately or publicly on the network. The final product can be printed (soon), watched on screen, played with like a toy, or shared through a worldwide library. Storybird is also a simple publishing platform for writers and artists that allows them to experiment, publish their stories, and connect with their fans.

  • The machine is effective in recycling different kinds of plastic into oil.
  • Utilization doesn't just take into account the 20 percent of recycled plastic. But it also considers the incinerated 52 percent used for energy recovery like generating electric power or heat. Akinori Ito says "If we burn the plastic, we generate toxins and a large amount of CO2. If we convert it into oil, we prohibit CO2 production and at the same time, increase people's awareness about the value of plastic garbage"
  • Oil from Shale: Oil can be extracted from this fine grained, organic rich, sedimentary rock through pyrolysis, thermal dissolution or hyderogentation. Shale contains high concentrations of organic chemical compounds known as Kerogen. From this solid mixture, oil is extracted through chemical process. Shale can be effective converted into combustible oil shale gas and liquid hydrocarbons (shale oil). Global deposits of Shale are estimated to be around 2.8 trillion to 3.3 trillion barrels of restorable oil. Planet earth is blessed with about 600 known oil shale deposits, most of which is found in United States of America. Although several countries have oil hale deposits, known deposits of economic importance is found only in 33 countries.

  • improved media literacy dramatically increased students' exposure to diverse perspectives and increased the likelihood of youth online engagement
  • among adults as well, Internet users were more civically-engaged
  • outh engagement in interest-driven online communities was associated with increased volunteer and charity work and in increased work with others on community issues. The Internet can serve as a gateway to online and offline civic and political engagement, including volunteerism, community problem-solving, and protest activity.
  • Roland Gesthuizen on 26 Feb 11
     
    "Arguably, the upheaval, activism and revolutions in of the last two months may serve to counter what has been a longstanding stereotype: youth are largely apolitical. Moreover, those that do participate in politics and activism online do so in shallow ways, the so-called "slacktivism." But recent findings from a longitudinal study of high school-age students challenges these notions, suggesting that youth who pursue their interests online are more likely to be engaged in civic issues."
