Edtech Digest today runs an interview with one of the Wolfram brothers, part of a research group that designs software to help people learn.
Here’s his November 2010 Ted Talk
The real and only important problem pointed out in this talk is that there are four steps to math, according to Wolfram, but we are spending the bulk of our time teaching kids to do the part of math that computers already know how to do well. It’s like we ignore the fact that we have computers at our disposal, and we’re forcing kids to reinvent the wheel of their own education, as if it was really going to teach them something. Wolfram says we should spend the bulk of our teaching time on these three highlighted areas:
And here is a segment of his interview with edTech:
Victor: In your 2010 TED talk, you say, “we have a real problem with math education right now”—how would you characterize that problem in U.S. schools, is it the same internationally? What’s wrong, essentially? Why? What do you suggest we do about it?
Conrad: There are different layers of the problem. Let me try to peel them off from the outside. To start with, most people–parents, employers, students and teachers—aren’t that happy with math education. It’s hard to find people who say “math in America is great” … Why is this? Well, math is more and more important so the pressure on it to deliver has gone up, yet students’ abilities don’t seem to have gone up; and very few find math fun either! Why is this? In my view a key reason, bluntly: we’re teaching the wrong subject. A chasm has opened up between the subject of math in education and math outside. I think of math as having 4 steps:
1. Posing the right questions
2. Real world –> math formulation
4. Math formulation –> real world, verification
In education, we spend perhaps 80 percent of the time on step 3 by hand, yet it’s rarely used outside above the most basic arithmetic. Computers (and don’t forget phones, iPods and iPads) do that bit—and usually much better than any human could!
So let’s do the same in education. Let’s teach the other steps much more, with harder, more realistic problems. There are some cases where hand calculating is still useful—like estimating—but that’s the exception not the rule. The default assumption should be “computers do the calculating”.
This isn’t just a U.S. problem; it’s everywhere; and the country that solves this first will get a great boost in technical competency and its important economic and societal consequences.
