    Psychologist Barry Schwartz takes aim at a central tenet of western societies: freedom of choice. In Schwartz's estimation, choice has made us not freer but more paralyzed, not happier but more dissatisfied.

    As we work together to restore hope to the future, we need to include a new and strange ally-our willingness to be disturbed. Our willingness to have our beliefs and ideas challenged by what others think. No one person or perspective can give us the answers we need to the problems of today. Paradoxically, we can only find those answers by admitting we don't know. We have to be willing to let go of our certainty and expect ourselves to be confused for a time

    We are all time travelers... drifting through time at a steady pace, one moment at a time. In what direction are we moving through time? Or does time move through us? How many dimensions of time are there? Though slightly allegorical, three-dimensional time offers physics new parameters, accounting for conventional and exotic physical phenomena, while maintaining the conservation of energy and symmetry groups found in physical law.  I began playing with the idea that all of physics could be reduced to just interactions between spatial and temporal coordinates. I wondered if inertia and momentum might be composed strictly of temporal components. This would require extra time dimensions. Could inertia or momentum be used as indicators of multi-dimensional time? What about charge, spin, and other properties of matter? Answers to some of these questions appeared to reside in neutrino research, specifically neutrino flavor oscillation.  The universality between Thermodynamics and Temporal Mechanics can reduce the fundamental forces of nature into a single expression, a new equivalence principle, which can be used as the generator for the evolution of time. Once Quantum Mechanics is seen through the lens of three-dimensional time, the EPR paradox looses its mystique. The speed of light may be restricted to a set speed limit within each individual frame of reference, however, frames of reference can undergo periods-of-time at varying rates of the passage-of-time. If the positive side of absolute zero is a state of condensed matter, what is on the negative side of absolute zero? Uncondensed matter?  The anti-matter aspect of the Dirac equations may have been misinterpreted. The convention is to assume that "matter" is composed of "particles" distinctly different from "antimatter" composed of "antiparticles". The assumption of one time dimension locks in this interpretation of the Dirac Equations. However, the uniform production of particles and antipa

    "Countries with greater gender equality see a smaller proportion of women taking degrees in science, technology, engineering and mathematics (STEM), a new study has found. Policymakers could use the findings to reconsider initiatives to increase women's participation in STEM, say the researchers. Dubbed the 'gender equality paradox', the research found that countries such as Albania and Algeria have a greater percentage of women amongst their STEM graduates than countries lauded for their high levels of gender equality, such as Finland, Norway or Sweden."

  • The current structure of the school day is obsolete, most would agree. Created during the Industrial Age, the assembly line system we have in place now has little relevance to what we know kids actually need to thrive
  • Yet therein lies the paradox. It’s exactly during these uncertain times when people must be willing to try new things, to be more open, curious and experimental, she said. In education, although there are great new models of learning and schooling, they are the exceptions, and the progressive movement has not gained much momentum.
  • “One thing we know for sure is that kids learn better when teachers are invested and paying attention and showing they care,” she said. “The biggest impact you’ll have as a teachers is the relationship you establish with your student.”

  • The five criteria that Challenge Success brings to schools attempts to modernize the obsolete system in place today: scheduling, project based learning, alternative assessment, climate of care, and parent education.
  • Research shows that kids do better in classes where teachers know their names and say hello to them, and when they have their own advocates or advisers at school.

  • The central paradox of the machines that have made our lives so much brighter, quicker, longer and healthier is that they cannot teach us how to make the best use of them; the information revolution came without an instruction manual.
  • The only way to do justice to our onscreen lives is by summoning exactly the emotional and moral clarity that can’t be found on any screen.
  • MAYBE that’s why more and more people I know, even if they have no religious commitment, seem to be turning to yoga, or meditation, or tai chi; these aren’t New Age fads so much as ways to connect with what could be called the wisdom of old age.

  • Other friends try to go on long walks every Sunday, or to “forget” their cellphones at home. A series of tests in recent years has shown, Mr. Carr points out, that after spending time in quiet rural settings, subjects “exhibit greater attentiveness, stronger memory and generally improved cognition. Their brains become both calmer and sharper.”
  • I noticed that all their talk was of sailing — or riding or bridge: anything that would allow them to get out of radio contact for a few hours.
  • empathy, as well as deep thought, depends (as neuroscientists like Antonio Damasio have found) on neural processes that are “inherently slow.” The very ones our high-speed lives have little time for.
  • I’ve yet to use a cellphone and I’ve never Tweeted or entered Facebook. I try not to go online till my day’s writing is finished, and I moved from Manhattan to rural Japan in part so I could more easily survive for long stretches entirely on foot, and every trip to the movies would be an event.
  • Nothing makes me feel better — calmer, clearer and happier — than being in one place, absorbed in a book, a conversation, a piece of music.
  • For more than 20 years, therefore, I’ve been going several times a year — often for no longer than three days — to a Benedictine hermitage, 40 minutes down the road, as it happens, from the Post Ranch Inn. I don’t attend services when I’m there, and I’ve never meditated, there or anywhere; I just take walks and read and lose myself in the stillness, recalling that it’s only by stepping briefly away from my wife and bosses and friends that I’ll have anything useful to bring to them.

  • First, students tend to lose interest in whatever they’re learning. As motivation to get good grades goes up, motivation to explore ideas tends to go down. Second, students try to avoid challenging tasks whenever possible. More difficult assignments, after all, would be seen as an impediment to getting a top grade. Finally, the quality of students’ thinking is less impressive. One study after another shows that creativity and even long-term recall of facts are adversely affected by the use of traditional grades.

      Very true; especially the "avoiding challenging tasks" part.
  • Unhappily, assessment is sometimes driven by entirely different objectives--for example, to motivate students (with grades used as carrots and sticks to coerce them into working harder) or to sort students (the point being not to help everyone learn but to figure out who is better than whom)
  • Standardized tests often have the additional disadvantages of being (a) produced and scored far away from the classroom, (b) multiple choice in design (so students can’t generate answers or explain their thinking), (c) timed (so speed matters more than thoughtfulness) and (d) administered on a one-shot, high-anxiety basis.

  • The test designers will probably toss out an item that most students manage to answer correctly.
  • the evidence suggests that five disturbing consequences are likely to accompany an obsession with standards and achievement:
  • 1. Students come to regard learning as a chore.
  • intrinsic motivation and extrinsic motivation tend to be inversely related: The more people are rewarded for doing something, the more they tend to lose interest in whatever they had to do to get the reward.
  • 2. Students try to avoid challenging tasks.
  • they’re just being rational. They have adapted to an environment where results, not intellectual exploration, are what count. When school systems use traditional grading systems--or, worse, when they add honor rolls and other incentives to enhance the significance of grades--they are unwittingly discouraging students from stretching themselves to see what they’re capable of doing.
  • 3. Students tend to think less deeply.
  • 4. Students may fall apart when they fail.
  • 5. Students value ability more than effort

      This is the reinforcement of a "fixed mindset" (vs. (growth mindset) as described by Carol Dweck.
  • They seem to be fine as long as they are succeeding, but as soon as they hit a bump they may regard themselves as failures and act as though they’re helpless to do anything about it.
  • When the point isn’t to figure things out but to prove how good you are, it’s often hard to cope with being less than good.
  • It may be the systemic demand for high achievement that led him to become debilitated when he failed, even if the failure is only relative.
  • But even when better forms of assessment are used, perceptive observers realize that a student’s score is less important than why she thinks she got that score.
  • just smart
  • luck:
  • tried hard
  • task difficulty
  • It bodes well for the future
  • the punch line: When students are led to focus on how well they are performing in school, they tend to explain their performance not by how hard they tried but by how smart they are.
  • In their study of academically advanced students, for example, the more that teachers emphasized getting good grades, avoiding mistakes and keeping up with everyone else, the more the students tended to attribute poor performance to factors they thought were outside their control, such as a lack of ability.
  • When students are made to think constantly about how well they are doing, they are apt to explain the outcome in terms of who they are rather than how hard they tried.
  • And if children are encouraged to think of themselves as "smart" when they succeed, doing poorly on a subsequent task will bring down their achievement even though it doesn’t have that effect on other kids.
  • The upshot of all this is that beliefs about intelligence and about the causes of one’s own success and failure matter a lot. They often make more of a difference than how confident students are or what they’re truly capable of doing or how they did on last week’s exam. If, like the cheerleaders for tougher standards, we look only at the bottom line, only at the test scores and grades, we’ll end up overlooking the ways that students make sense of those results.
  • the problem with tests is not limited to their content.
  • if too big a deal is made about how students did, thus leading them (and their teachers) to think less about learning and more about test outcomes.
  • As Martin Maehr and Carol Midgley at the University of Michigan have concluded, "An overemphasis on assessment can actually undermine the pursuit of excellence."
  • Only now and then does it make sense for the teacher to help them attend to how successful they’ve been and how they can improve. On those occasions, the assessment can and should be done without the use of traditional grades and standardized tests. But most of the time, students should be immersed in learning.
  • the findings of the Colorado experiment make perfect sense: The more teachers are thinking about test results and "raising the bar," the less well the students actually perform--to say nothing of how their enthusiasm for learning is apt to wane.
  • The underlying problem concerns a fundamental distinction that has been at the center of some work in educational psychology for a couple of decades now. It is the difference between focusing on how well you’re doing something and focusing on what you’re doing.
  • The two orientations aren’t mutually exclusive, of course, but in practice they feel different and lead to different behaviors.
  • But when we get carried away with results, we wind up, paradoxically, with results that are less than ideal.
  • Unfortunately, common sense is in short supply today because assessment has come to dominate the whole educational process. Worse, the purposes and design of the most common forms of assessment--both within classrooms and across schools--often lead to disastrous consequences.
  • grades, which by their very nature undermine learning. The proper occasion for outrage is not that too many students are getting A’s, but that too many students have been led to believe that getting A’s is the point of going to school.
  • research indicates that the use of traditional letter or number grades is reliably associated with three consequences.

    The message of Daniel Pinks book "Drive" applies here. Paying someone more, i.e. good grades, does not make them better thinkers, problems solvers, or general more motivated in what they are doing. thanks for sharing.

  • The paradoxical thing about information and searching is that the more of it there is, the less of it we will see. The results we retrieve will be a smaller and smaller sample of what's actually available. And I don't see how this trend can be reversed.
  • I don't speak Spanish, but can usually figure out the meaning of traveler's information printed in a couple of languages. My insufficiency became evident when searching online for information on La Posada, a Mexican Christmas tradition.
  • I wanted to know if there was traditional music for this Mexican celebration. I think I would have found it right away if there weren't other meanings and spellings for 'la posada.'

  • 20 slides at 20 seconds per slide, a Pecha Kucha is, as Jason writes, necessarily “SHORT, INFORMAL, and CREATIVE.”
  • In addition to the time constraint of the Pecha Kucha, your presentation must also follow the 1/1/5 rule. That is, you must have at least one image per slide, you can use each exact image only once, and you should add no more than five words per slide. The formal constraints of this rigid format call for discipline, focus, practice, and paradoxically, creativity.
