This chapter considers teaching in vocational classrooms, focusing specifically on automotive technology. We address two research questions in this chapter. 1) What are the discourse features of teaching in vocational education? 2) How, if at all, is teaching in a vocational context different from teaching in other contexts? Because learning in a vocational context contains a strong practical element, classes are divided between practical workshop-based classes where the tutor circulates between students working individually, and theory classes fronted by the tutor teaching all students at once. In this chapter we limit our attention to teacher-fronted theory teaching.
