“The traditional course is run by a professor, an instructor, who organizes the course material in some logical method and gives lecture materials and assigns readings. This is an approach that we can call either ‘teacher-centric,’ or maybe, ‘content-centric.’ And it fails to take into account the way people learn. The first step in learner-centric is to understand how learning takes place. Much modern research in cognitive science shows that people learn by doing. So it is very important that people learn not by reading a book, and not by listening to a lecture, but by doing tasks that can engage the mind.”
