This research explores "teaching excellence" by examining the perceptions of geography academics and students at Brunel University as to what makes a lecture "unmissable". The findings from 10 interviews with lecturers and five focus groups with undergraduate students suggest that whilst there is probably no such thing as an entirely unmissable lecture, attendance rates are significantly enhanced by three key factors: (i) a high degree of participation and interactivity ("active learning"), (ii) a clear structure which enables integrative links to be more easily made, and (iii) a passionate, enthusiastic lecturer, who can bring a subject to life for students. As research has shown that a high degree of interactivity encourages deeper approaches to learning, the paper argues that a move away from conventional lecturing towards more applied methods and small-group teaching may be a way of improving teaching excellence. Yet as large-group lectures are unlikely to be replaced any time soon, making them as participative as possible is one way to ensure that higher cognitive functions are at least partially acquired.
