From the Wikipedia:
"eLearning 2.0 refers to a second phase of e-Learning based on Web 2.0 and emerging trends in eLearning. It can include such features as e-Learning where students create content, collaborate with peers to form a learning network with distribution of content creation and responsibilities, e-Learning that takes advantage of many sources of content aggregated together into learning experiences and e-Learning that utilizes various tools including online references, courseware, knowledge management, collaboration and search.
The term suggests that the traditional model of eLearning as a type of content, produced by publishers, organized and structured into courses, and consumed by students, is reversed; so as that content is used rather than read and is more likely to be produced by students than courseware authors. Structure in eLearning 2.0, is more likely to resemble a blogging tool rather than a book or a manual."
