Most studies I've seen on the topic show that the best predictor of one's educational success and attainment is one's parents educational attainment, so there is something to that that an anecdote from a teacher that, aside from not being a systematic gathering of evidence, doesn't even describe an experience of what drives outcomes, but simply relates a personal practice, isn't really sufficient to rebut.
