Case-based instruction is widely used in management training, legal and medical training. Yet, there are few books written about case-based instruction, particularly in management. This book was written by the acknowledged master expert at discussion teaching, Roland Christensen. There is even a Christensen Center for Teaching and Learning at Harvard Business School). As it is true for most forms of expertise, most expert teachers find it difficult to to articulate their expertise. So do not expect to find a manual with "ten steps to successful discussion teaching". It is more of a personal reflection of Christensen's learning journey in this field, which makes it interesting to read, but sometimes you also feel like fast forwarding to get to the main points. I am still reading the book, so the three starts are my tentative rating at this point.
