Action research is action and research.
Action researchers find it useful to be skilled in communication, facilitation, and helping others learn. It also provides some information for those who may wish to start their own learning group, perhaps face to face. Other areol subscribers may or may not find it relevant. I would guess, though, that at least some of the concepts of group facilitation have wider application. They will be set up as mailing lists at Southern Cross University.
