This unit, one of six which comprise the Fair Play program, is designed to develop decision-making skills in middle school students. The Fair Play program is a series of student and teacher materials the purpose of which is to help students expand their female or male self-concepts, increase their decision-making skills, and improve their academic achievement by changing their stereotypic attitudes toward particular content areas. This teaching guide includes a brief description of the total program, an overview of the content of this unit, recommendations for instructional approaches, descriptions of program materials, a bibliography of print and audiovisual resources, and tips for small-group management. The bulk of this guide consists of the student guide which contains 12 lessons organized into four parts: (1) understanding that many decisions are made each day and identifying the decision maker; (2) developing five skills used in personal decision making; (3) making group decisions; and (4) applying new skills to situations in which decisions are made related to male and female self-concepts. Detailed annotations are provided to aid the teacher in planning and presenting each lesson. The final section provides a unit performance test with answer key. (DC)
