An insight into the individual learner, which is very different to the other evidence-based teaching books. The book focuses on research done in the classroom, as opposed to the lab, and measures and observes many things, such as: Previous and post-teaching knowledge, microphones on the students in the lesson, an observer noting down the students behaviour during the lesson to see what those students are focusing on (the content, doodling, friends, etc), and post-teaching interviews with the students to see what they thought about their own learning and where it had come from (teachers, friends, books, etc).
Well worth a read.
