He goes into why he started exploring the idea at first (students got 5's on their AP physics exams and had strong problem-solving skills — plug-and-chug — but poor conceptual understanding), the many iterations of the approach, and the data he collected on the way (significant increases in open-ended, conceptual problems, including at other schools that adopted the approach). Really fascinating.
