Magic Squares - 23 views

  •  
    "This is a maths resource that can be used to challenge pupils to complete a magic square, using only the numbers provided, to make sure that each row, column and diagonal all add up to the focused magic number. The resource provided challenges students to add up to 9, 12, 15 & 18, and could be used as a homework challenge, an additional classroom activity, or as a main activity within a maths lesson. Challenge pupils to work on two different methods for each magic number. This activity could be adapted with larger number, and other mathematic operations"

The Magic of Higher Education - Old School, New School - The Chronicle of Higher Education - 18 views

  • On a personal level, I find it difficult to connect with the corporate analogy. It is alienating, sterile, and ultimately…masculine.
  • When we view faculty as labor and students as customers, we do not see magic; we see expenses and revenue on a profit-and-loss sheet. We would be better off selling tickets to a magic show.

Many-to-One vs. One-to-Many: An Opinionated Guide to Educational Technology - The Ameri... - 9 views

  • MOOCs do not benefit most of those who try them. Students differ in their cognitive abilities and learning styles. Even within a relatively homogenous school, you will see students put into separate tracks. If we do not teach the same course to students in a single high school, why would we expect one teaching style to fit all in an unsorted population of tens of thousands?
  • I believe that the future of teaching is not one-to-many. Instead, it is many-to-one. By many-to-one, I mean that one student receives personalized instruction that comes from many educators. To make that work, technology must act as an intermediary, taking the information from the educators and customizing it to fit the student's knowledge, ability, and even his or her emotional state.
  • I am optimistic about tablets in large part because I believe that a magic bullet in educational technology is the adaptive textbook. By that, I mean an electronic textbook that adjusts to the cognitive ability and learning style of the student. Adaptive textbooks will query students in order to make sure that they understand what they have been studying. They will also respond to student queries. Adaptive textbooks will implement the many-to-one teaching model.

  • There are many horses in the educational technology race. The ones to bet on are adaptive textbooks and independent certification.
  • I do not believe that educators fully understand the process of social learning in the classroom. We do not know exactly what factors make the difference between a classroom where students are of significant help to one another and one where students provide little assistance or even hold one another back

    "This essay will explain why I label various technologies as winners, losers, and magic bullets in the table below. My opinions are not based on exhaustive research. They are based on my experience both as a high school teacher and as an entrepreneur." My evaluations are based on whether I view these technologies as supporting a model of education that is one-to-many or a model that is many-to-one. The latter is the model I prefer, as will become clear in the rest of this essay.

Psilocybin (magic mushrooms) - 0 views

  • The biosinthetic path that allow Psilocybin to be produced by mushrooms is as follow:
  • The several analogyes with triptophan aminoacid, with whom psilocybin has common origines are probably at the base of psilocybin ability to induced psychedelich alteration on humans.
  • Amino acids, including tryptophan, act as building blocks in protein biosynthesis. In addition, tryptophan functions as a biochemical precursor for many compounds like serotonin Serotonin (a neurotransmitter), synthesized via tryptophan hydroxylase. Serotonin, in turn, can be converted to melatonin (a neurohormone), via N-acetyltransferase and 5-hydroxyindole-O-methyltransferase activities
  • ...15 more annotations...
  • it's been noticed that psilocyn can indirectly raise dopamine concentration withing the basal ganglia.
  • Almost 50% of oral psilocybin is absorbed by stomach and gut; from here is lead to liver, where it's converted in psilocin, pharmacologically active form, that can furtherly be glucoronated and escreted with urine or converted in other psilocinics metabolites.
  • In rats, the median lethal dose (LD50) when administered orally is 280 milligrams per kilogram (mg/kg), approximately one and a half times that of caffeine. When administered intravenously in rabbits, psilocybin's LD50 is approximately 12.5 mg/kg
  • traces of the compund can be detected in unine even after 7 days.
  • Clinical studies show that psilocin concentrations in the plasma of adults average about 8 µg/liter within 2 hours after ingestion of a single 15 mg oral psilocybin dose; psychological effects occur with a blood plasma concentration of 4–6 µg/liter. Psilocybin is about 100 times less potent than LSD on a weight per weight basis, and the physiological effects last about half as long.
  • Within 24 hours from administration 65% of the alucinogen is escreted by urine, while another 15-20% is excreted by bile and feces.
  • Monoamine oxidase inhibitors (MAOI) have been known to prolong and enhance the effects of psilocybin. Alcohol consumption may enhance the effects of psilocybin, because acetaldehyde, one of the primary breakdown metabolites of consumed alcohol, reacts with biogenic amines present in the body to produce MAOIs related to tetrahydroisoquinoline and β-carboline. Tobacco smokers can also experience more powerful effects with psilocybin, because tobacco smoke exposure decreases levels of MAO in the brain and peripheral organs.
  • This could lead to a lower usage o f glucose, but the same study admitted an increase glucose usage by the whole brain cell, meaning a differente use of this sugar while the drug is having effects.
  • use of MRI (functional magnetic resounance) showed that the decresed blood flow associate with decreasing in neural activity. A simple explanation for this unexpected situation could be the serotoning agonist action of psilocybin, action that seems to be focused more on 5-HT receptors than on 5-HT2A.
  • psilocibyn is able to act as a 5-HT agonist binding directly its receptors.
  • augmented glucose consumption in several brain regions; this lead to the conclusion that psilocybin is some way able to modify the physiological glucosal metabolic rate of our body
  • The strong inibition of the PCC is now thought to be most significant action of psilocybin on neural disaccoppiation
    • Kenuvis Romero
       
      Lower brain glucose metabolism is linked with increased capacity for working memory.
  • Psilocybin comprises approximately 1% of the weight of Psilocybe cubensis mushrooms, and so nearly 1.7 kilograms (3.7 lb) of dried mushrooms, or 17 kilograms (37 lb) of fresh mushrooms, would be required for a 60-kilogram (130 lb) person to reach the 280 mg/kg LD50 value.
  • psilocybin can cause anxiety and increased heart rate and BP which is very counter- productive for someone on metoprolol and micardis.
  • propose the possibility to use psilocybin as a palliative therapy for terminal illness like cancer but also as a real antidepressive active principle available for the family of the patient. The rational is foundable in the fact that we usually administer SSRI as antidepressive agents, so psilocibyn sholud be useful in this purpose for its selective agonist action on 5-HT2A receptors

Book: 45 Secrets That All High School Teachers Need to Know by @RichardJaRogers - 36 views

  •  
    Mastering the art of teaching appears to be easier for some colleagues than others. Some teachers just seem to have a presence, gaining respect and credibility from students, colleagues and parents alike. Did they undergo some mysterious, magical training that wasn't covered during your teacher training course?  Well, no. They just have mastered how to manage their working relationships, using their personalities to generate rapport, which is respected by students of all age. It's not rocket science - it's far more complicated than that. Personality and behaviour clashes in classrooms are inevitable, but looking at all the different elements of daily interactions can help you gain respect from students and colleagues alike...

Review: How to teach Secondary Science by @CatrinGreen - 13 views

  •  
    We all remember science lessons from our school days. Whether the lessons were with the more 'characteristic' teachers in the school, or whether you all released the gas taps when the teacher foolishly left the room, we all seemed to miss the link that science is life! And what an opportunity science teachers have in releasing the magic of life to their pupils, answering BIG questions like "Why am I like my parents?", or "What will my life be like in 2050?", or "Why is Pripyat a deserted town?"
