Yes, I heard him by chance too. I hope that the conversation doesn't end in us or them statements. The reality, as we find talking with students constantly in schools, is that a mediocre teacher in a 40 minute period is far more preferable than a mediocre teacher in an 80 minute period. It's easy to teach in a direct style and the results are more consistent (see the research study attached and also in our research tab at isminc.com).
BUT, good/very good teachers are effective in a 40 minute period teaching content and MORE effective in an 80 minute period in teaching content and process. We are moving swiftly to a point where computers will be (and sometimes can now) teach content more effectively than teachers. Why have a teacher when a computer can do the job more reliably, without emotion, and over and over again in adaptive ways (e.g. aleks.com), not to speak of cheaper? We have to figure out what we actually need teachers to do and that comes back to effective teaching not being about style but about (I think another person said this earlier) relationships, about being immersed in the lives of children, about being enthusiastic, about have good technique, and so on and so on.
We are in a revolution. Willinngham is helpful in keeping us centered and focused on what actually works.
