Why were you so interested in how people learn, that you did research on the things that have large influences on how teachers teach and wrote a whole book on it?

“Most of us struggle to put into words how we learn and this is why I am most fascinated -- how can we create a language of learning how can we better understand how we learn and then how to learn better. I was great at recall and memory when I was a student but it only got me so far, and being even better at memory did not help -- I searched for ways to improve how to learn but my teachers just told me to invest more time, spend more time -- and it was the wrong answer” (John Hattie, personal communication, February 2, 2019).
