Threshold Concepts Symposium in 2010

As I am beginning to look at Ray Land’s work in Threshold Concepts and Troublesome Knowledge (which I first became aware of last year, though I went in a different direction then) as an element of the research design I am working on, I just became aware of the 3rd Biennial Threshold Concepts Symposium in July of 2010 in Australia. The conference site is here, and while the airfair from the East Coast in the US is astronomical at that time of the year, perhaps others may find this useful.

Now, to try to distinguish this from Jack Mezirow’s Transformative Learning theory. Anybody see anything that tries to show the similarities and differences?
