College sophomores at the United States Naval Academy were homogeneously sectioned in General Physics I and II during the academic year 1968-1969. The better students were selected for General Physics I on the basis of their QPR in their freshman year. The poorer students were selected for the second semester course on the basis of their grades during the first semester. The results were summarized on the basis of objective final examinations: (1) better students do equally well in either homogeneous or heterogeneous sections; and (2) poorer students do better when placed in heterogeneous sections rather than homogeneous sections. Instructors tend to grade daily work more liberally when teaching homogeneous sections of low ability. (Author/TS)
