Although we were required to lecture to large groups of over 170 students, the traditional lecture clashed with our commitment to teach in a way that was student-centred, relational and socially and politically transformative. In this context, and using an action research approach, we sought to turn our large-group lectures into a space that both met some of the historic aims of the lecture in passing on received knowledge, but also became a space for students to immediately engage in a process of discussion and dialogue around the concepts and ideas raised. Although the literature suggested this was not possible in groups of over a hundred, we found that our students identified that the re-imagined lecture significantly aided their learning in a number of key respects.
