The multidimensional issue of the representation of diverse students in special education has been a persistent and challenging concern for decades. Overwhelmingly, research outlining racial and ethnic disproportionality data have historically demonstrated stability in the overrepresentation of students of color in special education. However, the…

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…

This dissertation disaggregates the "Hispanic" category to examine the various factors shaping the educational trajectories of students who encompass this large ethnic group. This project consists of three studies, each presenting the perspectives of principal stakeholders: families, schools, and a community-based educational initiative.…

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…

Teachers sometimes fail to give varied teaching instructions that are suitable for a mixed-ability classroom because these instructions do not match students' proficiency levels. The current quasi-experimental quantitative study investigated the effectiveness of differentiated instruction strategies on students' overall English achievement. 60…

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…

School integration and inclusion are important for educational equity, yet inclusionary educational policies often end up being exclusionary in practices. In this article I contribute to our understanding of school level mechanism underlying this process. I draw on 2 years of data collection in a progressive culturally responsive school…

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 present investigation was an attempt to study the effect of using compensation and determination strategies on Iranian upper-intermediate EFL learners' vocabulary development. The question which the present study was trying to answer was: Do compensation and determination strategies have any statistically significant effects on Iranian upper-…

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…
