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'…

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…

A design experiment with 18 students in a regular seventh grade math class was conducted to investigate how to differentiate instruction for students' diverse ways of thinking during a 26-day unit on proportional reasoning. The class included students operating with three different multiplicative concepts that have been found to influence rational…

This study aimed to improve the van Hiele levels of geometric understanding, proof-construction performance and beliefs about proofs of the research respondents: future mathematics teachers exposed to the traditional (instructor-based) method and the enhanced-group Moore method. By using the quasi-experimental method of research, the study…

This action research study focused on how various grouping strategies influenced preservice teachers' differentiation of instruction. The participants included a third grade mentor teacher and three preservice teacher candidates. The candidate preparation curriculum consisted of seminars, daily field-based learning experiences, and ongoing…

Discusses research on cooperative learning groups and concludes that cooperative groups should often be homogeneous. (15 references) (MKR)

This review of the literature summarizes findings on instructional grouping issues and academic achievement of gifted elementary students. The review addresses problems of using standardized tests to evaluate instructional effectiveness of grouping arrangements, distinctions between providing the same curriculum and a differentiated curriculum to…

Most research on small group learning has focused on achievement, but few studies have systematically investigated the effects of group processes on achievement, or the influences of individual aptitudes and group composition on group processes. To investigate the relationship between student aptitudes, group process, and achievement in…

Thirty sixth graders in accelerated mathematics classes were taught in cooperative-learning teams for 12 weeks. Students appeared to benefit academically, personally, and socially from the cooperative-learning strategies used to teach mathematics, cooperative-learning skills, effective communications, internal locus of control, and personal…
