Amir Abo-Shaeer made a point at our Knowles Science Teacher's meeting that although every dutiful high school learns about logarithms, they really aren't that useful in the real world. Most people will simply never use them for anything functional. He referenced a TED talk in which Stephen Wolfram made the point that humans are really good at solving complex problems and thinking creatively, but not good at calculating. But calculators are really good at calculating and really bad at thinking creatively and solving complex problems... So... shouldn't we teach that - and let calculators do the rest? I love it. (To be fair, I watched the TED talk, and didn't get that out of it, but I'll leave it to you to hear for yourself):
One of the things I love about Amir's comments is that they're like a series of reality checks. Is this really worth it? (and the answer can be no). Is this the best it can be? How can it be more practical? I think John Dewey (the pragmatist educational philosopher) would approve of such an honest line of questioning.
