A very honest take. They tried something, it showed a very small improvement, and they acknowledged it. Acknowledging that the cause appears to be a lack of engagement agrees with my own experience. You can give students great tools but that doesn’t make them interested in math. Khanmigo might be a good tutor but it won’t help unless you’re chaining kids to a desk and not letting them leave until they finish some quota of problems.
