To teach physics is to make connections between different physical theories, phenomenal experiences, and the minds of students. To do this effectively requires a broad range of interpersonal skills and, crucially, effectively developed pedagogic content knowledge - how this has been done will be the focus of the workshop. Experience and research have shown that to learn effectively is not simply to sit at the feet of someone who has suitable qualifications and listen to them restate their understanding. Rather a reworking must take place that connects the learner to what is learned: to learn to reason in this subject is most fruitfully thought of as a kind of apprenticeship, and therefore requires interactive exemplification by a skilled practitioner. To begin to reason with physics, one must be able to use predictive models: so one needs to acquire a conceptual kitset with which to make connections appropriate to existing understandings. The exemplifying practitioner (a teacher) needs to have this kitset to hand, ready to deploy flexibly in response to the learner's reasoning. The Supporting Physics Teaching (SPT) materials and the TalkPhysics website both provide environments in which teachers can develop these conceptual kitsets: SPT contains many useful pre-formed parts but these cannot be absorbed passively. Teachers (whether physics graduates or graduates of other sciences) must re-work their own understanding in order to prepare the kitset for use in their own classroom. No amount of documentation seems to provide an alternative to this mentoring/coaching approach to developing teachers. It is that this reason that the SPT project developed the materials to support in-service training and that the TalkPhysics website is designed from the ground up to support a growing community of practice.
