Math! It seems to me that no subject (except maybe English) can frustrate so many learners. My friend Vanessa, who had a hand in creating the ix-quadrat math exhibit at the TUM, has taught me that children start out with mathematical gifts but lose them in school. So: what goes wrong?
I remember being very young when I noticed one January 1st that the year had changed. It dawned on me that the story of Jesus had happened in a time line and that years, like days and hours and minutes, were units that were all the same length. Wow!! Suddenly an abstract date became wonderfully real.
In school, I was enchanted by geometry, which I connected with origami, a hobby of mine. Finding out about pi was great, because I learned that numbers didn’t need to be integers (whole numbers) or fractions (one half etc.) to make perfect sense. Endless pi hinted at endless harmony just a step beyond my comprehension. Math, it seemed, was beautiful!Functions, too, had a satisfying symmetry — at first. But as they became more complex, I tried to find things in the real world connected to the charts we were drawing. Unfortunately, our teacher made no connection between the world outside and our math book. He gave up, presenting us with empty formulas and hating students for being stupid. And how we hated him back! In my most rebellious period, I handed in an empty test in protest. I caught up later only because a new teacher put the meaning back in by patiently explaining applications in the real world.
Taking the leap of faith into abstract mathematical thinking is not easy for us non-geniuses. In this “Year of Math”, the German government is doing a great job of creating interest in real-life applications for math, such as using the optimal skateboard jump curve to explain calculus. Other children learn by using easy interactive software, like MIT’s Scratch.
Still others need to identify with the mathematical systems as such. Ethno-mathematician Ron Eglash has found fractals to be the defining structural element in African society, from hair braids to fence building and the layout of villages. He uses “culturally situated” mathematics to create enthusiasm among African American students. Marvellous!
Wouldn’t it be nice to have more fun with math? Maybe some idealist will come up with a math blog for adults. Hey, Vanessa, do you have time on your hands? There must be others like me who would love to forget the crap we waded through in school and start over. Hello, out there, Genius: Your audience is waiting!
- See Ron Eglash’s wonderful talk at TED (also below). He’s created free “culturally situated” web design applets to experiment with.
- Origami fans, get your folding fingers ready for a beautiful video tutorial by the Peabody Essex Museum. (Thanks, Louise, for the link!)
- Your math brain is in a coma, like mine? Revive it here with all the math you need.
- Teaching math to English Language Learners in multilingual schools is a new challenge. See this article by Suzanne Irujo.
