The purpose of this paper is to summarize the issues and principal findings of research on homogeneous and heterogeneous ability grouping, and to consider the implications it may have for evaluating and improving the design of educational settings. To begin with, definitions of terms used in the discussion are given. The paper then proceeds to…

Subjects stratified by ability and extroversion initially achieved concept attainment in homogeneous (all introverts or all extroverts) or heterogeneous (one-half of the members extroverts) personality groups. Concepts were attained individually in a subsequent transfer stage. (Authors/JA)

Research tested the hypothesis that homogeneous subject groups would produce test responses with better homogeneity indices than those of the parent sample from which they were drawn. (Author)

In this paper consideration is given to the nature of the relationships among items within item forms and how these relationships compare with an ideal case for diagnostic tests in which if a person gets one item within an item form right then he would get all items within the item form correct.

A study of six gifted elementary students found that students in the homogeneous gifted class showed a greater increase in the number of control functions performed by the mind-machines they proposed, offered descriptions of their machines which were longer, more sophisticated, and more creative, and leap-frogged off of each others' ideas.…

The principal focus of this study is an investigation of whether students' grade point average (GPA) is a viable criterion for forming student work groups in the undergraduate Legal Environment of Business course. More specifically, the research focuses on the impact of: (1) GPA-homogeneous (HO) and GPA-heterogeneous (HE) groups upon student…

It was found that Ss from heterogeneous couples were less authoritarian than Ss from homogeneous couples. On three measures of prejudice (social distance, characteristics evaluation, and attitudes toward behavior expressing prejudice), it turned out that Ss from heterogeneous couples were less prejudiced than Ss from homogeneous couples.

A STUDY WAS CONDUCTED TO INVESTIGATE FEASIBLE CONDITIONS FOR ADAPTING SELF-INSTRUCTIONAL TECHNIQUES TO GROUP SETTINGS. THREE HYPOTHESES WERE TESTED--(1) THE TIME REQUIRED TO COMPLETE A PROGRAM BY A HETEROGENEOUS GROUP-PACED GROUP IS SIGNIFICANTLY GREATER THAN THAT OF A HETEROGENEOUS INDIVIDUALLY-PACED GROUP, (2) THE TIME REQUIRED TO COMPLETE A…

Cognitive and behavioral measures were administered to heterogeneous and homogeneous Mexican-American and Anglo groups at the beginning and end of the prekindergarten year. The results suggest that the learning environments of both homogeneous and heterogeneous groups have a facilitating influence. (SB)

A study was conducted to examine peer effects among 138 undergraduates at Williams College, a highly selective four-year liberal arts school. The study explored whether students would perform better writing about newspaper articles they read and discussed in academically homogeneous or heterogeneous groups of three. In homogeneous groups, all…

Examines the literature concerning the positive and negative effects of ability grouping, reporting on eighteen reading research studies. (RB)

A point-by-point criticism is made of F. H. Flynn's article, The Case for Homogeneous Sets in Mathematics'' (Mathematics in School, Volume 1 Number 2, 1972) in an attempt to show that the arguments used in trying to justify homogeneous grouping in mathematics are invalid. (Editor/DT)

Among the findings was that the heterogeneous groups showed more change on the FIRO scale. Also, on rating scales measuring positive feeling towards group, the initial superiority of homogeneous groups was reduced by the end of the T group and that heterogeneous groups manifested more significant increases.
