He even suggests ways to avoid answering students’ questions and commends his approach as one that works for teachers who don’t know the answers themselves.Īn early experiment conducted by John Sweller helps explain the surprising ineffectiveness of problem solving as a way of learning maths. We have known since the 1980s that asking students to struggle at solving problems with little teacher guidance is a terrible way of teaching maths and yet this is exactly what Finkel proposes. This is worrying because neither speaker feels the need to list any supporting evidence for the teaching approach that they both broadly suggest and that can be summarised by Finkel’s five principles: There is also a six year gap between the two talks, suggesting that these ideas are an enduring theme in commentary about U.S. The difference is that Meyer’s talk has more substance whereas Finkel focuses on the deep and meaningful presentation. To me, it is eerily reminiscent of Dan Meyer’s TED talk and perhaps Meyer is due a credit. It is called, “Five Principles of Extraordinary Maths Teaching” – a title worthy of the Extraordinary Learning Foundation™. The talk is by Dan Finkel and the fake quote is not actually the worst thing about it. Similarly, in the TEDx talk that I am about to discuss, we are treated to a fake Einstein quote about play being the highest form of research. ![]() ![]() How did he open his piece? With a fake Einstein quote about fish climbing trees. At the same time, he argued that the debate between traditionalism and progressivism is a pointless false dichotomy because all good teachers adopt a range of ‘teaching strategies’. Now a professional origami master, Lang practices his craft as both artist and engineer, one day folding the smallest of insects and the next the largest of space-bound telescope lenses.What is it with fake Einstein quotes? I recently read an amusing blog where the author set out a quintessentially progressive argument for abandoning traditional exams, setting kids project work and focusing on generic skills such as problem-solving over knowledge acquisition. His acuity for mathematics would lead him to become a physicist at the California Institute of Technology, and the owner of nearly fifty patents on lasers and optoelectronics. As a first-grader, Lang proved far too clever for elementary mathematics and quickly became bored, prompting his teacher to give him a book on origami. “The marriage of mathematics and origami harkens back to Lang’s own childhood. Each work is the result of software (which Lang himself pioneered) that manipulates thousands of mathematical calculations in the production of a “folding map” of a single creature.” His repertoire includes a snake with one thousand scales, a two-foot-tall allosaurus skeleton, and a perfect replica of a Black Forest cuckoo clock. “Origami, as Robert Lang describes it, is simple: “You take a creature, you combine it with a square, and you get an origami figure.” But Lang’s own description belies the technicality of his art indeed, his creations inspire awe by sheer force of their intricacy. According to TED.com: “Robert Lang is a pioneer of the newest kind of origami - using math and engineering principles to fold mind-blowingly intricate designs that are beautiful and, sometimes, very useful.”
