I’ve just returned home from a course focussed on, well, the above. In brief Burkin differentiated between these two practices.
Teaching practice is what you do in the class, whereas professional practice is everything else. Professional practice covers the quality of reports you write, meeting deadlines, how you conduct yourself and interact. Professional practice even includes journalling, professional readings and duty.
Teachers can be great at the teaching practice, but poor at professional practice. Good professional practice develops the teaching practice.
Additionally Burkin discussed being a teacher as a learner, or rather, ‘having a growth mindset’ compared to a fixed mindset. The fixed mindset is of course being happy for things to stay as they are.
