This module (part of a series of 24 modules) is on how stereotyped conceptions of minority children and their families may influence teachers' expectations and affect student achievement. The genesis of these materials is in the 10 "clusters of capabilities," outlined in the paper, "A Common Body of Practice for Teachers: The Challenge of Public Law 94-142 to Teacher Education." These clusters form the proposed core of professional knowledge needed by teachers in the future. The module is to be used by teacher educators to reexamine and enhance their current practice in preparing classroom teachers to work competently and comfortably with children who have a wide range of individual needs. The module includes objectives, scales for assessing the degree to which the identified knowledge and practices are prevalent in an existing teacher education program, and self-assessment test items. Topics discussed in this module include cultural diversity and ethnic stereotyping, characteristics of minority children and their families, and teacher expectations and student performance. A bibliography and journal articles are included on racial and cultural variations among American families, and the effect of cultural differences on the academic achievement of Mexican American children.
