I think you're right and that might give you an organizational structure for the body .... Use as a transition that you have 2 roles that many would consider very different, & discuss how. Then go on with the idea that being in the role of a learner is a great leveler. In my experience, pro-d course providers think that teachers should be quicker on the uptake. What they don't get is that teacher-students experience the same insecurities and struggles as regular students and that being in the learner role again forces us to face all sorts of old business. I think you've hit in something that could be fantastic. Let me know how it goes. (firstname.lastname@example.org).
