This report describes the measurable impact of the course, Human Relations, on student attitudes and a synthesis of views from extensive teacher interviews. (Technical aspects of the evaluation design, instrumentation, and tables are appended.) Experimental subjects were 811 students, grades 9-12, who were completing the semester course. 14 attitude scales were cast into three distinct forms: for blacks and whites; whites only; and, blacks only. The overall results indicate that the course has an effect on expressed verbal attitudes of students in accord with the general goals of the program, such as increased sensitivity and self-awareness. 26 high school teachers (representing 20 school systems) who use the curriculum were interviewed. Their subjective impressions were highly positive. Other teacher responses are also summarized. A "tentative and impressionistic" summary of elementary school teachers' responses is also provided. Finally, the authors discuss their concerns about the whole program. (DJB)
