Welcome!

For several months now Alison Stokes (University of Plymouth, UK), Helen King (University of Plymouth, UK) and Julie Libarkin (Michigan State University, US) have been discussing threshold concepts in the geosciences - what they are, how we recognise them, and the role that they play in becoming a geoscientist. The conversation is throwing up some fascinating suggestions and ideas which, rather than keeping to ourselves, we'd like to unleash on the wider geoscience community. A precis of our conversation to date will follow shortly, but essentially this blog will take over from our ongoing email discussion. Feel free to ask questions, add comments or put forward your own opinion - this is an emerging debate and one which you are all welcome to join!
