The Eide Neurolearning Blog has an interesting post on autobiographical memory. It seems to me that the best way to tap its power from the perspective of online learning is through discovery learning adventure games. Check out, for example, this great little action maze that teaches emergency first aid best practices. It was created using a great (and inexpensive) authoring tool called Quandary. By embedding the learning content into a first-person narrative experience, you should be able to acivate autobiographical memory.
