Although many of us would like to get beyond lecturing, we often lack concrete strategies for doing so, particularly in our larger classes. This paper suggests one such strategy for creating a discussion-based course. The success of such a course is predicated on students reading and thinking about the course material (receiving "first exposure") prior to attending class so that class time can be devoted to more substantively engaging activities grounded in guided discussion. The vehicle I propose for achieving this first exposure to the course material is the "Course Preparation Assignment" (CPA). This article explains the rationale for discussion-based courses, describes the development and use of CPAs, and assesses a discussion-based course by comparing it to a traditional lecture course on several outcomes. The assessment reveals that the use of these assignments to create a discussion-based course has been a great success, allowing me to foster student engagement with the course material by spending the majority of class time coordinating, facilitating, and leading discussions, rather than constantly lecturing at the students.
