When teachers complain about the ways that schools evaluate our teaching–and we do so with frequency and enthusiasm–one of the common refrains has to do with the measuring instruments and their inability to account for randomness and adjustment to randomness.  Many a hallway story involves a moment when a teacher’s plans became irrelevant and the teacher responded.  Sometimes in these stories we adapt.  Sometimes we invent.  But as often as anything else, we improvise, a word that we share with the worlds of jazz music and stage comedy.  Nick Sorensen has taken that moment and proposed ways to evaluate the work of teachers in more complex and ultimately more adequate ways, and his recent book The Improvising Teacher: Reconceptualising Pedagogy, Expertise, and Professionalism presents his research and some proposals for moving forward more intelligently.  Christian Humanist Profiles is glad to welcome Dr. Sorensen to the show.
