In this blog post I continue describing the forces that nurture intrinsic motivation. I have identified ten of these forces, and I will describe one per post over the next few months. Focusing on and emphasizing these forces helps teachers create an engaging, productive classroom environment that brings out the best in students. For teachers who may be a bit nervous about the prospect of managing a group of children without relying on rewards and punishments, these forces offer a far more powerful, far more genuine alternative to traditional classroom management approaches that are rooted in Douglas McGregor’s Theory X and depend on extrinsic motivation.
