> I am actually coming to the conclusion that experience is better than a study. I have seen so many counter-intuitive studies that have later had huge methodological issues. In addition, a lot of studies have small sample sizes I don’t think those are strong arguments for claiming experience is better than a study. Methodology-wise, experience doesn’t pose a hypothesis first and then tests it, and doesn’t statistically evaluate conclusions. That leads to the risk that conclusions get drawn on a few outliers or more ‘visible’ students. Sample size wise, decades of teaching or large classes will have more subjects, but they’ll be more diverse, too, and their attributes aren’t tracked well. On the plus side, experience doesn’t feel the “publish or perish” pressure. That significantly decreases the risk one starts shouting around conclusions that aren’t fully supported by the evidence.
