Yet MORE evidence math skills are not an innate ability:
Davis-Kean and colleagues analyzed how parents’ values and attitudes affect children’s math performance and later interest, and how these attitudes vary by the child’s gender. They used data from a longitudinal study of more than 800 children and a large group of their parents that began in 1987 and continued through 2000.
They found that parents provided more math-supportive environments for their sons than for their daughters, including buying more math and science toys for the boys. They also spent more time on math and science activities with their sons than with their daughters.
Another interesting paper:
I’d like to blame that C- in Calc 2 on this; but it was probably the beer consumption during college. (And that’s not innate either!)
