A keeper. Good.
I bought this for a university subject. At first I was unimpressed: a few of the earlier chapters had spelling/grammatical errors and were verbose, which I felt reflected poor editing. But not all chapters were the same and I found myself enjoying it more as I went. The content is interesting and engaging. I like how it refers to learning pedagogy throughout the world, such as Finland, and Cambodia. Even though this was a university-required text, it doesn't read like a boring manual: the chapters are short, engaging, and easy to read.
