This brochure, designed to acquaint teachers in Kansas City area public and parochial schools with the Inquiry Role Approach (IRA) to Biological Sciences Curriculum Study (BSCS) courses, prepares for their cooperation with the Mid-Continent Regional Development Laboratory (McREL) in testing an IRA model during the 1968-69 school year. Four program objectives are listed: to provide opportunity for pupils to develop and use social and inquiry skills which enable them to participate as responsible members of a team engaged in formulating and testing biological concepts and hypotheses, to provide assistance to the teacher in his guidance of student learning by providing resource materials and classroom organization designed to provide a climate in which his role is changed from information disseminator to learning situation manager, to help develop teacher skills in developing study guides and other curricular aids which facilitate the continued development of pupil inquiry skills and attitudes and student responsibility for his inquiry activities, to develop a packet of tested materials and classroom procedures which will be available for school and district adoption. Included are general notes on the methodology, a diagram of sequential steps in the IRA, an overview of the 5-year IRA project, and 18 pages of student comments on IRA. (JS)
