Go Ahead, Mess With Texas Instruments - Phil Nichols - The Atlantic - 0 views

  • If you had asked them, most of my high school teachers would have called me an unmotivated student or said that I lacked discipline and didn't take learning seriously. And yet, that abandoned storage bin told another story: with the aid of my calculator, I'd crafted narratives, drawn storyboards, visualized foreign and familiar environments and coded them into existence. I'd learned two programming languages and developed an online network of support from experienced programmers. I'd honed heuristics for research and discovered workarounds when I ran into obstacles. I'd found outlets to share my creations and used feedback from others to revise and refine my work. The TI-83 Plus had helped me cultivate many of the overt and discrete habits of mind necessary for autonomous, self-directed learning. And even more, it did this without resorting to grades, rewards, or other extrinsic motivators that schools often use to coerce student engagement.
  • I've now begun to see Texas Instruments graphing calculators as unique among educational technologies in that they enable learning that is couched in discovery more than formal teaching.
  • take the notion of "correctness." School typically assumes that answers fall neatly into categories of "right" and "wrong." As a conventional tool for computing "right" answers, calculators often legitimize this idea; the calculator solves problems, gives answers. But once an endorsed, conventional calculator becomes a subversive, programmable computer it destabilizes this polarity. Programming undermines the distinction between "right" and "wrong" by emphasizing the fluidity between the two. In programming, there is no "right" answer. Sure, a program might not compile or run, but making it offers multiple pathways to success, many of which are only discovered through a series of generative failures. Programming does not reify "rightness;" instead, it orients the programmer toward intentional reading, debugging, and refining of language to ensure clarity. This is a form of learning that privileges the process of discovery over the interventions of formal teaching. It can fuel an intrinsic desire to pursue similar learning experiences, but even more, it gradually transforms the outlook of the student

  • Subversion encourages students to take an imaginative stance toward learning, to embrace failure as an integral part of success, to see the world for what it is and consider what it might look like under a different set of conditions.
  • The iPad is among the recent panaceas being peddled to schools, but like those that came before, its ostensibly subversive shell houses a fairly conventional approach to learning. Where Texas Instruments graphing calculators include a programming framework accessible even to amateurs, writing code for an iPad is restricted to those who purchase an Apple developer account, create programs that align with Apple standards, and submit their finished products for Apple's approval prior to distribution. As such, for the average student, imaginative activities on an iPad are always mediated by pre-existing apps and therefore, are limited to virtual worlds created by others, not by students themselves. Pair this with the fact that most teachers and administrators only allow classroom use of a few endorsed apps and it becomes clear that these devices are doing more to centralize the school's authority over the learning process than to encourage self-directed creative activity.
  • learning to program taught habits of mind that persist to this day in small yet vital ways. In my work as a teacher, I often hear colleagues lamenting the widespread use of calculator games among students. They consider such forms of "play" an abuse of educational technology and a threat to student learning. But this assumption ignores the tacit learning that arises from repurposing conventional learning apparatuses. My TI-83 Plus awoke a curiosity that exerted a subtle but powerful push toward autonomy and self-direction.
  •  
    Learning to program a graphing calculator gave the author a deeper education. Results: intrinsic motivation and an ability to "embrace failure as an integral part of success", as well as developing creativity, problem-solving skills, and persistence. Interesting critique of the iPad as a more conventional tool of learning vs. subversive.

Is Algebra Necessary? - NYTimes.com - 0 views

  • Nor is it clear that the math we learn in the classroom has any relation to the quantitative reasoning we need on the job. John P. Smith III, an educational psychologist at Michigan State University who has studied math education, has found that “mathematical reasoning in workplaces differs markedly from the algorithms taught in school.”
  • It’s not hard to understand why Caltech and M.I.T. want everyone to be proficient in mathematics. But it’s not easy to see why potential poets and philosophers face a lofty mathematics bar. Demanding algebra across the board actually skews a student body, not necessarily for the better.
  • Instead of investing so much of our academic energy in a subject that blocks further attainment for much of our population, I propose that we start thinking about alternatives. Thus mathematics teachers at every level could create exciting courses in what I call “citizen statistics.”

  • I hope that mathematics departments can also create courses in the history and philosophy of their discipline, as well as its applications in early cultures. Why not mathematics in art and music — even poetry — along with its role in assorted sciences? The aim would be to treat mathematics as a liberal art, making it as accessible and welcoming as sculpture or ballet.
  •  
    A better question than "is Algebra necessary?" would be "how can we make it more relevant and compelling to students?"

5-Year-Olds Can Learn Calculus - Luba Vangelova - The Atlantic - 0 views

  • But this progression actually “has nothing to do with how people think, how children grow and learn, or how mathematics is built,” says pioneering math educator and curriculum designer Maria Droujkova.
  • The current sequence is merely an entrenched historical accident that strips much of the fun out of what she describes as the “playful universe” of mathematics
  • “Calculations kids are forced to do are often so developmentally inappropriate, the experience amounts to torture,” she says. They also miss the essential point—that mathematics is fundamentally about patterns and structures, rather than “little manipulations of numbers,” as she puts it.

  • Studies [e.g.,  this one, and many others referenced in this symposium] have shown that games or free play are efficient ways for children to learn, and they enjoy them.
  • start by creating rich and social mathematical experiences that are complex (allowing them to be taken in many different directions) yet easy (making them conducive to immediate play). Activities that fall into this quadrant: building a house with LEGO blocks, doing origami or snowflake cut-outs, or using a pretend “function box” that transforms objects (and can also be used in combination with a second machine to compose functions, or backwards to invert a function, and so on).
  • What is learned without play is qualitatively different. It helps with test taking and mundane exercises, but it does nothing for logical thinking and problem solving.

How a Radical New Teaching Method Could Unleash a Generation of Geniuses | Wired Busine... - 0 views

  • As she headed into fifth grade, she assumed she was in for more of the same—lectures, memorization, and busy work. Sergio Juárez Correa was used to teaching that kind of class. For five years, he had stood in front of students and worked his way through the government-mandated curriculum. It was mind-numbingly boring for him and the students, and he’d come to the conclusion that it was a waste of time. Test scores were poor, and even the students who did well weren’t truly engaged.
  • Juárez Correa didn’t know it yet, but he had happened on an emerging educational philosophy, one that applies the logic of the digital age to the classroom. That logic is inexorable: Access to a world of infinite information has changed how we communicate, process information, and think. Decentralized systems have proven to be more productive and agile than rigid, top-down ones. Innovation, creativity, and independent thinking are increasingly crucial to the global economy. And yet the dominant model of public education is still fundamentally rooted in the industrial revolution that spawned it, when workplaces valued punctuality, regularity, attention, and silence above all else.
  • knowledge isn’t a commodity that’s delivered from teacher to student but something that emerges from the students’ own curiosity-fueled exploration. Teachers provide prompts, not answers, and then they step aside so students can teach themselves and one another. They are creating ways for children to discover their passion—and uncovering a generation of geniuses in the process.

  • “So,” Juárez Correa said, “what do you want to learn?”
  • His defining principle: “The children are completely in charge.”
  • if you’re not the one who’s controlling your learning, you’re not going to learn as well,”
  • Peter Gray, a research professor at Boston College who studies children’s natural ways of learning, argues that human cognitive machinery is fundamentally incompatible with conventional schooling. Gray points out that young children, motivated by curiosity and playfulness, teach themselves a tremendous amount about the world. And yet when they reach school age, we supplant that innate drive to learn with an imposed curriculum. “We’re teaching the child that his questions don’t matter, that what matters are the questions of the curriculum. That’s just not the way natural selection designed us to learn. It designed us to solve problems and figure things out that are part of our real lives.”
  • He squatted next to her and asked why she hadn’t expressed much interest in math in the past, since she was clearly good at it. “Because no one made it this interesting,” she said.

Rethinking Advanced Placement - NYTimes.com - 1 views

  • While Ms. Vangos believes the program could inspire students who “like to think outside the box,” she worries that the new math requirements will discourage others.
    • Peter Kronfeld
       
      Yikes! Why? This is the perfect opportunity to show students how math connects to the real world.
  • She is also frustrated by the predictable nature of many of the “dirty dozen,” the teachers’ nickname for the basic lab exercises now recommended by the College Board. In one that her class did last fall, the students looked at pre-stained slides of onion root tips to identify the stages of cell division and calculate the duration of the phases. She and her students, who historically score 4’s and 5’s on the exam, were one of several schools asked by the College Board to road test one of the proposed new labs to see if it brought back the “Oh, wow!” factor. The basic question: What factors affect the rate of photosynthesis in living plants? The new twist: Instead of being guided through the process, groups of two or three students had to dream up their own hypotheses and figure out how to test them. Caroline Brown, a senior who stages the school’s plays, connected the lab to her passion for theater. She borrowed green, sky blue and “Broadway pink” filters from the playhouse to test how different shades of light affected photosynthesis in sunken spinach leaves.

      Fantastic! Seems like the new labs encourage creative thinking instead of demanding adherence to a procedure.
  • But many of the courses, particularly in the sciences and history, have also been criticized for overwhelming students with facts to memorize and then rushing through important topics. Students and educators alike say that biology, with 172,000 test-takers this year, is one of the worst offenders. A.P. teachers have long complained that lingering for an extra 10 or 15 minutes on a topic can be a zero-sum game, squeezing out something else that needs to be covered for the exam. PowerPoint lectures are the rule. The homework wears down many students. And studies show that most schools do the same canned laboratory exercises, providing little sense of the thrill of scientific discovery.

  • The goal is to clear students’ minds to focus on bigger concepts and stimulate more analytic thinking. In biology, a host of more creative, hands-on experiments are intended to help students think more like scientists.

If You've Got the Skills, She's Got the Job - NYTimes.com - 0 views

  • Many years ago, people learned to weld in a high school shop class or in a family business or farm, and they came up through the ranks and capped out at a certain skill level. They did not know the science behind welding,” so could not meet the new standards of the U.S. military and aerospace industry. “They could make beautiful welds,” she said, “but they did not understand metallurgy, modern cleaning and brushing techniques” and how different metals and gases, pressures and temperatures had to be combined.
  • Welding “is a $20-an-hour job with health care, paid vacations and full benefits,” said Tapani, but “you have to have science and math. I can’t think of any job in my sheet metal fabrication company where math is not important. If you work in a manufacturing facility, you use math every day; you need to compute angles and understand what happens to a piece of metal when it’s bent to a certain angle.” Who knew? Welding is now a STEM job — that is, a job that requires knowledge of science, technology, engineering and math.
  • even before the Great Recession we had a mounting skills problem as a result of 25 years of U.S. education failing to keep up with rising skills demands, and it’s getting worse.

Test-Taking Cements Knowledge Better Than Studying, Researchers Say - NYTimes.com - 0 views

  • Taking a test is not just a passive mechanism for assessing how much people know, according to new research. It actually helps people learn, and it works better than a number of other studying techniques.
  • These other methods not only are popular, the researchers reported; they also seem to give students the illusion that they know material better than they do.
  • The second experiment focused only on concept mapping and retrieval practice testing, with each student doing an exercise using each method. In this initial phase, researchers reported, students who made diagrams while consulting the passage included more detail than students asked to recall what they had just read in an essay. But when they were evaluated a week later, the students in the testing group did much better than the concept mappers. They even did better when they were evaluated not with a short-answer test but with a test requiring them to draw a concept map from memory.

  • “Educators who embrace seemingly more active approaches, like concept mapping,” he continued, “are challenged to devise outcome measures that can demonstrate the superiority of such constructivist approaches.”
  • “More testing isn’t necessarily better,” said Dr. Linn, who said her work with California school districts had found that asking students to explain what they did in a science experiment rather than having them simply conduct the hands-on experiment — a version of retrieval practice testing — was beneficial. “Some tests are just not learning opportunities. We need a different kind of testing than we currently have.”

  • “We’re trying to take kids who haven’t been engaged in school and hook them to an expanded vision of what their future might be,” he said. When they return to their own schools, the hope is that they’ll be more interested in history, math and English — and have a sense of environmental stewardship as well.
  • “The most important thing really is teaching kids through hands on, experiential learning,” said Rees. “Our kids do this because they’re inspired to be there every week, to work with adults and do hands on things.”

How Tests Make Us Smarter - NYTimes.com - 0 views

  • used properly, testing as part of an educational routine provides an important tool not just to measure learning, but to promote it.
  • Various kinds of testing, though, when used appropriately, encourage students to practice the valuable skill of retrieving and using knowledge.
  • tests serve students best when they’re integrated into the regular business of learning and the stakes are not make-or-break, as in standardized testing.

  • researchers have also found that the most common study strategies — like underlining, highlighting and rereading — create illusions of mastery but are largely wasted effort
  • Just as it is with the multiplication tables, so it is with complex concepts and skills: effortful, varied practice builds mastery.
