This guidebook presents definitions, components, examples, evaluation criteria, and aids for the development and evaluation of Learning Activity Packages (LAP), which are sets of integrated, competency based instructional materials aimed at developing proficiency in one or more topics of instruction. The first chapter sets forth definitions, in operational terms, of four important concepts in the guidebook: Learning Activity Package, competency statement, terminal objective, and enabling objective. Major components of the LAP instructional system are defined and described in chapter 2 as: (1) competency statements; (2) rationale; (3) objectives; (4) instruction; (5) evaluation; and (6) feedback. Chapter 3 describes the organization and contents of the three main sections of LAP: the preliminary pages, the text, and reference matter. The fourth chapter sets forth a systematic process for the development and evaluation of LAPs. Explanations are given of each step in the process. The standard format and layout scheme employed in developing a LAP is outlined in chapter 5. The appendices include sample LAP pages, a detailed statement of work for contracts to write LAPs, and LAP evaluation forms. (JD)
