A casework approach study of the River Acres Independent School District, Texas, is presented. The study is descriptive, not evaluative; and observations are supplemented by quotations taken during interviews with teachers, students, administrators, parents, counselors, and other school personnel. The purpose of the study is to describe the teaching methods and the K-12 curriculum in mathematics, science, and social science. An introductory section provides background information about the urban area, the school district, administration, rules, planning, parent involvement, teacher and student evaluation, open space design, student preparation, competition, changes in the student population, and instructional levels. Curriculum areas are discussed according to educational level: (1) elementary schools; (2) junior high school; and (3) senior high school. For each subject at each educational level, information and quotations on topics such as problems, tests, instructional levels, curriculum, and open space are presented. (MH)
