Fundamentally, I’d teach with it the same way as with any other book. Most of the chapters have a very similar structure: section of story, section of statistics, section of story, section of statistics, section of story. So, in most chapters there are two large sections of statistics that are book-ended by story, and there’s a bit of story in the middle to offer some light relief. As such, it’s fairly easy to ignore the story if you want to. The sections of statistics are all written as conversations between the main character and various people he meets. The academic content is what you’d expect to find but presented as a conversation between a student (the main character) and a teacher (the particular character in the story who is teaching him). This sort of Socratic style is a good tool for teaching because the main character (hopefully) asks the same sorts of questions that students often want to ask. Of course, you should feel free to embrace the story if that suits your teaching style, and I could imagine giving lectures that begin by setting the scene of the story, or which end with the chapter cliff-hangers. I’d love to hear of people doing that, but ultimately you have to do what works for your teaching style.
