  • Therefore, school districts need to add elements of comprehensive induction  to their mentoring programs to help promote learning and professionaldevelopment.

      I think that this is one thing that HCPSS does well with the New Teacher orientation--especially because it happens a week before verteran teachers come back.

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]

  • have been lucky enough to have taught the full range of our freshman / sophmore undergraduate offerings as both an onsite and online instructor. While I have thoroughly enjoyed both formats - and very much so - I must admit that my experiences online have been *much* more positive than onsite instruction. Let me try and elucidate:1. While in the onsite classroom you have the opportunity to think on your feet and challenge and be experiential on your feet to reactions to the students who speak, in the online classroom, you are able to meet *every* class member and challenge their minds and ideas. The students who would normally be lost in a classroom of 35-40 are met and developed each day or week at their level and pushed to consider ideas they might not have considered. 2. I am able to reach the entire class through multimedia exhibits in each of the weekly units - journal articles, non-copyrighted film clips (and many from our university's purchased collection under an agreement for both onsite classroom and online classroom use), photography, art, patents, etc, that the students would not see - or would otherwise ignore - in an onsite classroom. We incorporate this information into our discussions and make it part of the larger whole of history.3. Each student and I - on the phone during office hours or in e-mail - discuss the creation of their term papers - and discuss midterm and final "anxiety" issues - and as they are used to the online format, and regular communication with me through the discussion boards, they respond much more readily than onsite students, whom I have found I have to pressure to talk to me. 4. I am able to accommodate students from around the country - and around the world. I have had enrolled in my class students from Japan, Indonesia, India, England - and many other countries. As a result, I have set up a *very* specific Skype address *only* for use of my students. They are required to set up the time and day with me ahead of time and I need to approve that request, but for them (and for some of my students scattered all over the state and US), the face time is invaluable in helping them feel "connected" - and I am more than happy to offer it. 5. As the software upgrades, the possibilities of what I can offer become more and more amazing, and the ease of use for both me - and for the students -  becomes astronomically better. Many have never known the software, so they don't notice it - but those who have taken online courses before cheer it on. Software does not achieve backwards. As very few of these issues are met by the onsite classroom, I am leaning more and more toward the online classroom as the better mode of instruction. Yes, there are times I *really* miss the onsite opportunities, but then I think of the above distinctions and realize that yes, I am where I should be, and virtually *ALL* the students are getting far more for their money than they would get in an onsite classroom. This is the wave of the future, and it holds such amazing promise. Already I think we are seeing clear and fruitful results, and if academics receive effective - and continuing - instruction and support from the very beginning, I cannot imagine why one would ever go back. The only reason I can think of *not* doing this is if the instructor has his or her *own* fear of computers. Beyond that - please, please jump on the bandwagon, swallow your fears, and learn how to do this with vigor. I don't think you will ever be sorry.PhD2BinUS

    I am a graduate student at Sam Houston State University and before I started grad school I never had taken an online course before. My opinion then was that online courses were a joke and you couldn't learn from taking a course online. Now my opinion has done a complete 180. The teachers post numerous youtube videos and other helpful tools for each assignment so that anyone can successfully complete the assignment no matter what their technology skill level is. I do not see much difference between online and face-to-face now because of the way the instructors teach the courses.
