This unit, one of six which comprise the Fair Play program, allows middle school students to compare and analyze male and female language. 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 the guide consists of the student guide which contains 20 lessons organized into four parts: (1) basic principles of language and its effects on people; (2) differential treatment of males and females in written language; (3) examination of verbal and nonverbal communication of males and females; and (4) practice in making personal and group decisions. 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)
