Experiential learning, the new entry of the TEL Dictionary

What does exactly mean "experiential learning"? Is it learning serendipitously from an eventful life or is it learning from empirically from experiences one managed for you or that you managed yourself? How far is this concept from "inquiry learning" or "exploratory learning"?

The documented definitions of Experiential learning prepared by Vyara Dimitrova and Paul Kirschner for the TEL Dictionary clarify these issues and are excellent basis for further discussion.

One more question: would "experiential learning" from an educational perspective be a concept enhancing our tool box to understand the theoretical tensions between informal and formal learning?
