Kathy Sierra on learning theory:
Learners are not “empty vessels” waiting to be filled with content pushed into it by an expert, blogger, author, etc. Learning is something that happens between the learner’s ears–it’s a form of co-creation between the learner and the learning experience. You can’t create new pathways in someone’s head… your job is to create an environment where the chances of the learner “getting it” in the way that you intend are as high as possible.
