E-learning 2.0

The Internet is turning into a participating community where consumers and producers of resources merge into "prosumers", dialectically sharing their knowledge, their interests and needs. This Web 2.0 archetype is now strongly impacting on e-learning methodologies and technologies, by enforcing the participation of students in creating and sharing materials and resources. Overcoming latent alarms introduced by the coming out of new complex tools, e-learning 2.0 represents a new challenge for accessibility. The production of accessible contents can now be turned from an impossible mission centrally managed by teachers and institutions to a joint work of people improving learning materials.
