In the last two decades, there has been a proliferation of Web-based course-management systems designed to facilitate postsecondary teaching (for example, WebCT, Blackboard, Desire2Learn, Moodle). In general, these systems provide analogs for delivering lectures, holding class discussions, giving quizzes and examinations (typically multiple choice), and assigning papers and group work--or some combination of these. This chapter describes a Web-based program (CAPSI) based on well-researched principles of behavior. Among the innovations of the program is a peer-review component. The program has been well accepted by administrators, staff, and students at institutions where it is or has been used.
