We investigated how the level of variance in students' prior knowledge may have influenced their collaborative interactions and science learning in small groups. We examined learning outcomes from 102 groups from seven science teachers' classes and discourse from two contrasting groups: Homogeneous versus heterogeneous. We examined individual and…

The degree of homogeneity and heterogeneity among schools affects the comprehensiveness and inclusiveness of the school system and the type and scope of classroom interaction. Since the beginning of the 1980s, interest has gradually increased in the effects of homogeneity and heterogeneity of schools on classroom interactions; this research…

This article presents a research study on the interactional styles of teacher educators in the English language teacher education classroom. Two research methodologies, ethnomethodological conversation analysis and self-evaluation of teacher talk were applied to analyze 34 content- and language-based classes of nine English language teacher…

Although a growing literature has documented the effectiveness of informal group work during class sessions, virtually no data exist on which students are collaborating. As a result, instructors rarely know whether students are self-sorting in ways that maximize learning. This article explores which undergraduate students worked together on each…

The primary purpose of this study is to investigate the influence of racial and gender diversity on group process and problem solving in an academic setting. The importance of this dynamic is its value in preparing students for the workplace. The supposition is if a group is homogeneous, commitment and performance is improved. Data for the study…

This paper discusses the use of student groups in formal education. A model is proposed which involves the development of student interdependence on common tasks, the use of group incentives which may be earned through competition with a standard or with other groups, and the exchange of student resources in teaching and learning. In contrast to…

This paper provides an overview of research and theory on within-class grouping for instruction, including how groups are formed and managed, how students interact in groups, and how grouping affects students' achievement, with particular concern for low-achieving students served by Chapter 1 of the Education Consolidation and Improvements Act of…
