Steven Strogatz' wrote a blog post about what it was like to be a beginner at teaching through inquiry. This second part contains his experience of teaching a Mathematics Exploration class at Cornell University using ideas from "Discovering the Art of Mathematics":

What happened over the rest of that semester turned out to be the most astonishing, uplifting experience I’ve ever had as a teacher.
