I’ve seen a lot of reshares of this report about the long-term effect of gender bias in elementary math, which comes from an NBER working paper about a study of Israeli schools. The usual presentation highlights one specific result, namely that on a math test graded by teachers who knew the names of the students,…

Math with Bad Drawings has a post about “word problems” that will sound very familiar to anyone who’s taught introductory physics. As he notes, the problem with “word problems” for math-phobic students is that it requires translating words into symbols, and then using the symbols to select a procedure. It adds a step to what…

Rhett and I did the 15th episode of our Uncertain Dots hangout yesterday, commenting on a discussion started by Casey Rutherford about what we would like students coming into college physics to know.

That’s billion with a ‘b.’” and urges people to “Get your billion back!” by paying for their…

The other morning, I was lying in bed and for some reason, found myself wondering what the population of Niskayuna is. While this is easily Google-able, as I said, I was in bed, and didn’t want to get up to get a device with Internet connectivity. So I tried to Fermi-problem my way to an…
