Imaginary Geometry - Kanizsa Figures by @CambridgeMaths - 32 views

  •  
    "Italian psychologist Geatano Kanizsa first described this optical illusion in 1955 as a subjective or illusory contour illusion. The study of such optical illusions has led to an understanding of how the brain and eyes perceive optical information and has been used considerably by artists and designers alike. They show the power of human imagination in filling in the gaps to make implied constructions in our own minds. Kanizsa figures and similar illusions are a really useful way to encourage learners to 'say what they see' and to explain how they see it. It offers a chance for others to become aware of the different views available in a diagram and share their own thoughts without the 'danger' of being wrong; many people see different things."

  • We have to train people to tackle situations they have not encountered before. Most instructors avoid this like the plague, because the students dislike it. Even at Harvard, we tend to keep students in their comfort zone. The first step in developing those skills is stepping into unknown territory.

BYOD - Worst Idea of the 21st Century? : Stager-to-Go - 127 views

  •  
    Schools and school districts who have come to the personal computing party decades late now have conjured a cheap less-empowering way to produce an illusion of modernity. They call it "Bring Your Own Device" (BYOD) or "Bring Your Own Technology" (BYOT) and it's a terribly reckless idea for the following reasons.

Inside the School Silicon Valley Thinks Will Save Education | WIRED - 9 views

ISSIE LAPOWSKY DATE OF PUBLICATION: 05.04.15. 05.04.15 TIME OF PUBLICATION: 7:00 AM. 7:00 AM INSIDE THE SCHOOL SILICON VALLEY THINKS WILL SAVE EDUCATION Click to Open Overlay Gallery Students in the youngest class at the Fort Mason AltSchool help their teacher, Jennifer Aguilar, compile a list of what they know and what they want to know about butterflies. CHRISTIE HEMM KLOK/WIRED SO YOU'RE A parent, thinking about sending your 7-year-old to this rogue startup of a school you heard about from your friend's neighbor's sister. It's prospective parent information day, and you make the trek to San Francisco's South of Market neighborhood. You walk up to the second floor of the school, file into a glass-walled conference room overlooking a classroom, and take a seat alongside dozens of other parents who, like you, feel that public schools-with their endless bubble-filled tests, 38-kid classrooms, and antiquated approach to learning-just aren't cutting it. At the same time, you're thinking: this school is kind of weird. On one side of the glass is a cheery little scene, with two teachers leading two different middle school lessons on opposite ends of the room. But on the other side is something altogether unusual: an airy and open office with vaulted ceilings, sunlight streaming onto low-slung couches, and rows of hoodie-wearing employees typing away on their computers while munching on free snacks from the kitchen. And while you can't quite be sure, you think that might be a robot on wheels roaming about. Then there's the guy who's standing at the front of the conference room, the school's founder. Dressed in the San Francisco standard issue t-shirt and jeans, he's unlike any school administrator you've ever met. But the more he talks about how this school uses technology to enhance and individualize education, the more you start to like what he has to say. And so, if you are truly fed up with the school stat

      The F-pattern when reading online could have been helpful for the reader in this article.
  •  
    Both the author of the article and the people she criticizes are making a fundamental mistake. It is an illusion that kids once learned facts in some deeper way. If the tree octopus had been presented in a book, the kids would have made the same mistake. Much of traditional teaching was not about absorbing certain facts but about learning techniques for accessing those facts. The internet and google really have changed the way we access information. The real challenge is how to restructure knowledge itself to take advantage of the new forms of accessibility. And as for using technology in the classroom: banning computers is like forcing kids to memorize arithmetic tables in an age when everyone has a calculator. We don't need slide rules nor an abacus and there is no reason to teach kids how to use them.

How I Rewired My Brain to Become Fluent in Math - Issue 17: Big Bangs - Nautilus - 2 views

  • By championing the importance of understanding, teachers can inadvertently set their students up for failure as those students blunder in illusions of competence. As one (failing) engineering student recently told me: “I just don’t see how I could have done so poorly. I understood it when you taught it in class.” My student may have thought he’d understood it at the time, and perhaps he did, but he’d never practiced using the concept to truly internalize it. He had not developed any kind of procedural fluency or ability to apply what he thought he understood.
  • Time after time, professors in mathematics and the sciences have told me that building well-ingrained chunks of expertise through practice and repetition was absolutely vital to their success. Understanding doesn’t build fluency; instead, fluency builds understanding. In fact, I believe that true understanding of a complex subject comes only from fluency.

  • We attended church at the Grace & Truth Gospel Hall on 14th Avenue South, where a preacher clutched his suspenders and spoke glowingly of Eternity, and I grew up one of the Brethren, the Chosen to whom God had vouchsafed the Knowledge of All Things that was denied to the great and mighty. The Second Coming was imminent, we would rise to the sky. We walked around Minneapolis carefully, wary of television, dance music, tobacco, baubles, bangles, flashy cars, liquor, the theater, the modern novel—all of them tempting us away from the singular life that Jesus commanded us to lead.

  • There were the neon lights of Hennepin Avenue and the promise of naked girls at the Alvin Theater, which our family passed on Sunday morning on our way to church, but that was lost on me, a geek with glasses, pressed pants, plaid shirt, a boy for whom dating girls was like exploring the Amazon—interesting idea, but how to get there? Writing for print, on the other hand—why not? And then came the beautiful connection: You write for print, it impresses girls, they might want to go on dates with you.
  • For days after Frankie drowned, I visited the death scene, trying to imagine what had happened. He was paddling a boat near the shore, and it capsized, and he drowned. I imagined this over and over, imagined myself saving him, imagined the vast gratitude of his family. I don’t recall discussing this with other boys. We were more interested in what lay ahead in seventh grade, where (we had heard) you had to take showers after gym. Naked. With no clothes on. Which turned out to be true. Junior high was up the West River Road in Anoka, the town where I was born, 1942, in a house on Ferry Street, delivered by Dr. Mork. That fall of seventh grade, he listened to my heart and heard a click in the mitral valve, which meant I couldn’t play football, so I walked into the Anoka Herald and asked for a job covering football and basketball, and a man named Warren Feist said yes and made me a professional writer. Ask and ye shall receive.
  • down to work at 4 a.m. to do the morning shift on KSJN in a basement studio on Wabasha and then a storefront on Sixth Street, the house where I lived next to Luther Seminary and the backyard parties with musicians that inspired A Prairie Home Companion at Macalester College, the dramatic leap to home ownership on Cathedral Hill in St. Paul, where I’ve lived most of the last 20 years, where you drive up from I-94 past Masqueray’s magnificent cathedral, whose great dome and towers and arches give you a momentary illusion of Europe, and up Summit and the mansions of 19th-century grandees and pooh-bahs in a ward that votes about 85 percent Democratic today.

Not a big ponytail. A little one. I had a beard too.” And she looks at me. “A ponytail? Are you joking?

Education Week: Does NCLB Promote Monolingualism? - 5 views

  •  
    By requiring all students to demonstrate what they have "learned" in multiple subject areas through standardized tests written in English, and by reducing resources for helping students become multilingual, the U.S. continues to build a wall between our nation and the global community.
  •  
    For our children's sake, we can't keep promoting the illusion that Americans are so superior to the rest of the world that we can or should insist that our way (language, culture, politics) is the best or only way. Within the context of our current standardized testing culture, common standards reinforce the fallacy that all children *should* learn (and are able to learn) the same things - and to the same level of performance - at a particular age.

  • life isn't as simple as it once appeared. Career and Marriage are transformed from abstract hopes into concrete decisions. Every one that is made closes off other possibilities.

Shared Governance Is a Myth - Commentary - The Chronicle of Higher Education - 14 views

  • It takes years of rank and the bitter­sweet experience of extensive committee service to realize that faculty influence on the operation of the university is an illusion, and that shared governance is a myth.
  • Committees report to administrative officers who are at liberty to accept, reject, or substantially alter faculty recommendations.
  • One would think that faculty senates exercise jurisdiction over a range of college life and policy. In reality, the right of many senates does not extend beyond making recommendations to the president, who is under no obligation to accept them.

  • A more probable source of this way of doing business is the residue of an old ideal of the university. Such survivals of previous practices are not unusual in social life. Physicians, for example, experience a struggle between two competing understandings of their field: the prevalent view that treating patients is a business, and the residue of the old ideal that it is a calling. Ministers live the same ambiguity. Faculty committees constitute the respect that today's university pays to the old notion that it is a community of students and scholars. The impotence of the committees is acknowledgment that at this time in history, institutions of higher education are business ventures, in certain ways similar to factories.
  • If education is primarily a business, managers hire the faculty. If universities are communities of students and scholars, faculty members hire the managers.
  • The growing disempowerment of the faculty is accelerated by the distance of governing boards from campus processes.

  • The Evolution of Time and the Carnot Cycle at the Edge of the Universe
  •  
    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
