As I said, it's simply an anecdote of teacher tracking, and you've mischaracterized what I've said. I've noticed all semester long he's been ignoring girls trying to participate, and on the last day my daughter raised her hand the entire class, not just once. Still, as I said, it's an anecdote, not statistically significant, but if you want statistical evidence, teacher tracking is a real and widely known problem with lots of studies and policy discussions.
