This report presents a collection of position papers and mission statements and traces the ways in which these papers contributed to an orderly sequence of events that resulted in the choosing of the Laboratory mission. Position papers cover the areas of full education, curriculum, instructional methods, and teacher education. The alternative mission proposals, which evolved from these position papers, cover the areas of (1) personnel requirements and educational change, (2) teacher education, (3) the interaction of educational variables, (4) teacher training product assessment, (5) the goals of education, and (6) communication and information services. The "Laboratory Mission Comparison Scale," used to compare the six proposals and to make a selection, is included. (Pages 59-97 and 164-306 may reproduce poorly.) (JF)
