Interface Design for Learning

This is an excellent introduction to a rather obscure topic - designing interfaces to applications that support learning. There's a lot of detail and a lot of examples of best practice. The target audience is both technical people like myself, and more designey folks. It attempts (and I think succeeds) to bridge the gap between interface design and UX, and educational theory, in order to help people develop software and websites that engage students and help them actually learn. I only finished reading it a week ago, and already it's enabled me to give a very knowledgeable take on gamification in a conversation. If you're even remotely working in this field, this is a worthwhile read.
