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…

Many methods have been developed for managing groups in active learning classes, but little research has been done on the effect of group structure itself. Results are presented for an active learning physics class in which half of the class was placed in academically homogeneous groups while the other half was in heterogeneous groups. Students…

The problem of assigning students to teams can be described as maximising their profiles diversity within teams while minimising the differences among teams. This problem is commonly known as the maximally diverse grouping problem and it is usually formulated as maximising the sum of the pairwise distances among students within teams. We propose…

In the present study, we were interested in the appraisal by teachers who have had experience with an individual form of differentiation of the efficiency of grouping learners into homogenous or heterogeneous groups. In the study, seven aspects were thus considered: (1) the learning performance and motivation of learners, (2) the learners'…

Cooperative learning pedagogy has been in place for more than 40 years. Nevertheless, there has been no consensus on the best grouping procedure for the cooperative learning activities. To shed more light on the issue, the present study examined the language achievement of learners at different ability levels in two heterogeneous and homogenous…

High-quality helping behavior is essential for effective peer interaction and learning. This study focused on ethnic group composition and the quality of group interaction as predictors of individual mathematics performance. Video-observations of 92 fifth-grade students working in groups balanced on mathematics performance level were analyzed. We…

In the blocked-cyclic naming paradigm, participants repeatedly name small sets of objects that do or do not belong to the same semantic category. A standard finding is that, after a first presentation cycle where one might find semantic facilitation, naming is slower in related (homogeneous) than in unrelated (heterogeneous) sets. According to…

We present research on the attitudes of seniors and juniors doing a major in English toward different grouping strategies for cooperative learning at Can Tho University, Can Tho city, Vietnam. The collected data is analyzed by a means of quantitative approach. The findings not only facilitate the further understanding of English majors' opinions…

The purpose of this quasi-experimental, ex-post facto study was to determine through quantitative analysis of longitudinal data, the effects of homogeneous differentiation on reading achievement. Specifically, the study sought to determine the achievement differences in reading of students who were taught using a within-class grouping method or a…

It is through working in groups that students develop cooperative learning skills and experience. However, group work activity often leads students into a difficult experience, especially for first-year students who are not familiar with group work activities at university. This study explores obstacles faced by first-year students during their…

The purpose of this quantitative study was to determine the effectiveness of one specific freshman mathematics intervention program on improving students' mathematics knowledge and to examine student perceptions and attitudes towards mathematics. Students participating in the mathematics intervention program were assigned to two math classes each…

Among comprehension instructions that encourage collaborative learning, Collaborative Strategic Reading (CSR) and Questioning the Author (QtA) were known for their effectiveness. Both help students on improved comprehension of text and building a positive relationship among themselves. Similarly, Ability Grouping and Self-efficacy were factors…

Group work is often a key component of student-centered pedagogies, but there is conflicting evidence about what types of groups provide the most benefit for undergraduate students. We investigated student learning outcomes and attitudes toward working in groups when students were assigned to groups using different methods in a large-enrollment,…

Most children experience some form of grouping in the classroom every day. Understanding how teachers make grouping decisions and their impacts on children's social development can shed light on effective teacher practices for promoting positive social dynamics in the classroom. This study examined the influence of teachers' grouping strategies on…

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…
