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.

Will Africa Produce the 'Next Einstein'? | WIRED - 0 views

  • There are three formal AIMS undertakings: a master’s degree program in Mathematical Sciences, research, and teacher training. The master’s program offers free tuition to accepted students and trains them in both general principles – problem formulation, the scientific method, communication – and cutting-edge math in subjects including computer science, biomathematics, and financial mathematics. Research will allow for international collaborations and advanced student training.

  • Traditionally, classrooms were led by an authoritative teacher who disseminated information to silent students, but Zomahoun hopes to turn that paradigm on its head. “We train people who can challenge the status quo,” he explains, “not just people who learn from books, listen to lectures, and just repeat it.” Rather, he hopes to instill qualities like “critical thinking, independent thinking, and problem solving” in order to prepare students for real-world problems.

The Ugly, Corrupted, Brilliant Games of Michael Brough | Game|Life | Wired.com - 0 views

  • Corrypt, upon proper exploration, revealed itself to be a brilliantly designed puzzle game, unforgiving and unwilling to accommodate players who refuse to give it their full attention. Peel back one layer, and it reveals another more surprising one.
  • After completing a degree in math and computer science at the University of Auckland, Brough moved to London and began working towards a Ph.D. He landed a decent-paying programming job while continuing his scholastic work, but continued making games, including the beautiful, abstract strategy game Vertex Dispenser, which even Brough admits may have been too esoteric. It combined elements of shooters and real-time strategy games with a complex puzzle system, and many players felt overwhelmed. “I just could not get my head around those concepts at the same time,” said one.
  • Well-designed games, he believes, can teach people how to do some things better. By simulating challenging situations, games can teach us about “managing unexpected situations… making good decisions, thinking about the costs of our actions and dealing with the consequences,” he says.

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.

      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.
