Paper reviews the test for regression lines and provides equations for expanding this test to regression planes. (Author)

The use of ability grouping restricts students to interact with others who have been identified as similar in ability and carries with it the stigma of failure and the operation of the self-fulfilling prophecy. (Author)

In a five-year study, second-year human physiology students were grouped for laboratory according to previous physiology and laboratory experience. No significant differences in course or board examination performance were found, though correlations were found between predental grade-point averages and grouping. (MSE)

Forty third graders divided into average and below average reading skill groups were given a story comprehension task that consisted of two conditions, listen through and think aloud. Average readers generated significantly more explanatory inferences and comprehension performance as measured by story recall was significantly better for both…

This article examines recent trends and the literature on grouping with emphasis on possible negative effects of heterogeneous grouping on gifted students. Guidelines from three recent publications all supporting some level of grouping are listed. (DB)

Discusses teaching in schools with heterogeneous grouping and in those with homogeneous grouping. Supports multiability classrooms and describes the benefits. Suggests techniques to deal with the range of student ability. (SR)

Questions whether the benefits of separating basic writers into homogeneous classes continue to outweigh the disadvantages. Proposes that teachers gather data about success rates of current basic writing courses (using "mainstreamed" volunteer basic writers) and revise first-year composition courses to ensure they will respond to a wider range of…

A study compared the performance of heterogeneous and homogeneous instructional groups, and of individuals within these groups, when group members all received the same grade. High-ability students obtained lower grades in heterogeneous groups than in homogeneous groups, with the reverse true for lower-ability students. Lower-ability students…

Describes a transition in a mature Special Care Unit for Alzheimer's patients, where patient mix had become too diverse for intended programming. Since the patients were unable to become involved in premove planning and preparation activities, preparation of staff substituted for the involvement of residents. Improved discharge policies maintain…

Argues that global challenge created by the pressure for change requires educators to understand the balance between continuity and constant change dependence and independence, individualism and community, homogeneity and heterogeneity. To achieve balanced learning and development, education should place greater emphasis on continuity,…

An experiment was conducted to investigate the innovative performance of problem solving groups (n=196) with three different blends of cognitive styles. As predicted, groups with a heterogeneous blend of styles outperformed groups with completely or partially homogeneous blends. Participant satisfaction, however, was lower for heterogeneous teams.…

This article examines the relationship between student perceptions of team learning experience and communication style. Student group learning perceptions were evaluated and team communication style was measured using dyads derived from Myers-Briggs personality profiles. Groups containing similar personalities were classified as compatible,…

This collection of articles is intended to demonstrate that there is solid research to justify both ability grouping and cooperative learning with gifted students and that each approach should be used judiciously to address particular student needs. Introductory material describes the philosophy and program policy of the Center for Talented Youth…

The literature review presented here was conducted to investigate various types of differentiation in programs for academically gifted elementary school students. For the purpose of the review, the term "academically gifted" refers to students with high general intellectual ability; no speciic level of intelligence is implied. Following…
