  • Fractions are as easy as pigs
  • One way to help students to understand the basics of adding and subtracting fractions (denominators must be the same; add/subtract the numerators; DO NOT add/subtract the denominators) is to teach the students what the parts of a fraction really are: numbers and names. This also helps combat the frequently-taught but incorrect idea that a fraction and a ratio are the same. A ratio may look like a fraction, but it is not a fraction.
  • FRACTIONS ARE AS EASY AS PIGS What is 2 pigs plus 3 pigs? 5 pigs (Write as a fraction: 2/pigs + 3/pigs = 5/pigs) Notice, we do not end up saying the answer is 5 horses.

  • The top of a fraction is a NUMBER: 1, 2, 3, etc. The bottom of a fraction is a NAME: half, third, fourth, etc. We can add and subtract numbers. We cannot add and subtract names.
  • Fraction Blackjack
  • Ask each student their "denominator." Don't give it away. Ask each one until one finally says their name. Continue through the room... Their name is their denominator. When you practice adding and subtracting fractions with like denominators, actually say "pigs" instead the fraction name. Then say, "Instead of pigs, we are using ..." and let them answer with the appropriate denominator. It is fun when doing subtraction to say, "If we have 5 pigs and eat 3 pigs, besides a stomachache, what is left?"
  • The transition to unlike denominators is automatic. If the names are not the same, you can't add the fractions. 2/pigs + 3 horses is still 2/pigs and 3/horses (unless we discover a "common denominator" -- a common name: farm animals). Once the students know they must have a common name (denominator) in order to add or subtract, they have a reason to learn about common denominators. By the way, I always begin common denominators without worrying about the Least Common Denominator (LCD). Once they can find a common denominator (multiply the denominators), add or subtract, and then reduce, they can be led to finding "easier" denominators to work with. Students who have too much difficulty with LCD can still get the correct answer; they just have more reducing to do. Those who can find a lower common denominator have less reducing. This is a very basic rendering of "Fractions are as easy as pigs." AWP, 10/12/00 on teachers.net math board
  • Denominate means: to name Political parties nominate (name) their candidates. Religious denominations are identified by their names. The denominations of money are the names of the coins and bills.
  • One game that my students enjoy the challenge of is Blackjack 1. You need a set of fraction cards per student (or you can make them from index cards.) The same rules as Blackjack apply. Instead of trying to get to 21, they want to try and get close to 1 without going over. With this game they practice addition and comparing -- it's great. You can also make it more challenging or bring in mixed numbers with Blackjack 2 or Blackjack 3. (Blackjack 2 means to try to get as close to 2 as possible without going over.) I am not sure where to buy fraction cards. I have one set that I received when I took over a classroom. However, I have always had the students create their own sets and we used them for several games. I gave each students a set of index cards (3 1/2 X 5) and they wrote the fractions in pencil so they couldn't be seen through the cards. These are the fractions we included: all fractions with a denominator of 2, 3, 4, 5, 6, 8, 10, and 12. (To challenge the students you may want to use the 7, 9, and 11 denominators as well.) I also had the students include 2 0's such as 0/3 and 0/4 and two 1's such as 3/3 and 4/4. Each game required two sets of cards, so I had the students write their initials in the corner of their set so they would get a complete set back after the game.

  • Fraction War Fraction War with the fraction cards: It is just like the card game of War, but with the fraction cards instead. This game helps students to compare fractions and encourages them to use number sense in comparison before using the algorithm of making equivalent fractions. Memory Memory with the fraction cards: It is just like the traditional "Memory" game, but any equivalent fractions are considered a match so 1/2 would be a match with 2/4. This game helps them to identify equivalent fractions. You can also play this game with fraction to decimal equivalence by making a set of decimal cards too. Fraction/Decimal Bingo Fraction/Decimal Bingo: The students have game boards with decimals on them. You call out fractions and if they have the decimal equivalence they can mark it on the board.

  • But Wait! There's More.Again
  • There is yet another advantage ETFs have over mutual funds
  • and that is their tax benefit
  • However, unlike mutual funds, ETFs do not sell stocks to pay for redemptions
  • As people withdraw their money from a mutual fund, the mutual fund must sell securities to cover those redemptions. So, every time the mutual fund sells a stock, you have to pay capital gains tax on it.
  • This being the case, the capital gains that you must pay on an ETF are much less than that of a mutual fund because of the lack of capital gains.
  • Danger, Will Robinson!

  • But, just like any other mutual fund, you have to pay fees
  • Vanguard will charge you managerial fees to set up and manage the fund.
  • The ETF's Potential Disadvantage
  • they do have a potential drawback
  • What it really depends upon is how much you are going to invest and how frequently you are going to invest.
  • If you're only going to invest $200 a month in an ETF, the $20 commission results in an immediate 10% loss,
  • Just something to think about before you jump into ETFs.

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.
  • Emphasis is on the collaborative nature of learning and the importance of cultural and social context.

  • 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.
    • robert morris
       
      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.

Lines on Plagiarism Blur for Students in the Digital Age - NYTimes.com - 12 views

  • Digital technology makes copying and pasting easy, of course. But that is the least of it. The Internet may also be redefining how students — who came of age with music file-sharing, Wikipedia and Web-linking — understand the concept of authorship and the singularity of any text or image.

  • Ms. Brookover, who works at the campus library, has pondered the differences between researching in the stacks and online. “Because you’re not walking into a library, you’re not physically holding the article, which takes you closer to ‘this doesn’t belong to me,’ ” she said. Online, “everything can belong to you really easily.”

Diigo VS Delicious « Bibliweb's Blog - 60 views

    "Vous l'avez certainement remarqué, en ce moment beaucoup de professionnels de l'information migrent de Delicious à Diigo. Effet de mode ou véritable révolution? Pour tenter de le savoir, je vous propose un comparatif qui, je l'espère, vous aidera à choisir entre l'une ou l'autre des plateformes. Delicious et Diigo fonctionnent sur le même principe: ils vous permettent d'enregistrer vos favoris en ligne. Jusque-là tout va bien : la manipulation se fait en quelques clics que ce soit avec l'un ou avec l'autre. Mais une fois que l'on a créé et les favoris importés, on se retrouve dans deux univers très différents. diigo Diigo: réseau social ou l'outil de travail ? Dès la page d'accueil on trouve une ressemblance très forte avec les sites de réseaux sociaux: un profil avec vos informations personnelles, vos activités récentes ainsi que celles de vos amis. Car dans Diigo, vous avez des amis, avec qui vous pouvez converser et travailler en groupe. Le plus ? Le travail en commun permet en autre de créer une liste fermée de mots-clés pour indexer vos favoris., ce qui évite les listes de tags interminables et peu pertinentes. L'organisation des mots-clés par liste thématique peut s'avérer utile notamment lorsque l'on souhaite créer une liste de signets pour le public de la bibliothèque. Le moins ? Il faut bien dire qu'on a du mal à distinguer le véritable enjeu du site, tant le coté social est présent.
