Abstract

A review of the current literature suggests that the concept of purpose has not received sufficient theoretical or pedagogical attention. In this article, theoretical depth is provided by a discussion of four components of purpose: purpose as associated with discourse types, purpose from the writer's viewpoint, purpose as it relates to situation, and purpose from the reader's viewpoint. Research is cited, and examples from computer documentation are used to illustrate each component. Cooperation and conflict among components are examined in a sample document, and classroom applications are discussed.
