"This book is a brief introduction to modern evidence-based teaching practices and how to use them to teach programming to free-range learners. It cover: how people's thinking changes as they go from being novices to competent practitioners and then to being experts ; how to tell if your learners are keeping up with you, and what to do or say when they're not ; how to design and improve lessons efficiently and collaboratively ; how and why live coding (i.e., writing programs step by step in front of learners) is a better way to teach programming than lectures or self-directed practice ; and how insights and techniques borrowed from the performing arts can make you a better teacher."-- Publisher's website.
