I did not find Flipping 2.0 to be as useful to me. The book presents how teachers have implemented the flipped classroom. The many chapters are written by the teachers themselves, and the quality of writing is as varied as their approaches to the flipped classroom. What they do have in common is the fact that they are all elementary or secondary school teachers. Many chapters discuss the technology they use, which I was interested in, but unfortunately it is often quite specific to the level and school systems.
Flipping 2.0 is supposed to be different from Flip 101 (Bergmann and Sams) in that it is more student-centered and targets higher-level thinking by the students. That is, Flip 101 was basically the notion that we move the lecture onto podcasts that are viewed prior to class by the students at home, while homework and worksheets were done in class with the help of the teacher. Flipping 2.0 instead tries to create a better use of the face-to-face time with students; don't do simple homework problems in class but rather introduce problem-based learning or other active learning techniques. This is good advice, although I already viewed Flip 101 as being designed to address higher-level thinking.
Despite the uneven quality, I did find a few chapters that were helpful.
