Break up your lectures: or Christaller sliced up

Abstract

Expounding for an hour is, we argue, a relatively poor way of teaching a large group during a ‘lecture’ period. Problems with such conventional lectures are discussed and a method outlined which overcomes some of these problems. In this method, which we shall call structured lectures, the lecture period is divided up into segments. Only some of these segments involve the lecturer talking. In others students discuss topics or complete exercises set by the teacher. An example of such a lecture on aspects of Christaller's central place theory is described both to indicate how to use structured lectures and to discuss the issues that teachers have to confront to adopt this strategy successfully.
