Differentiation and achievement grouping are frequently implemented practices to adapt education to students' varying educational needs based on achievement level. Potential didactical and socioemotional advantages and disadvantages of these practices have been discussed in the literature. However, little is known about the perspective of students…

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…

There does not appear to be consensus on how to optimally match students during the peer feedback process: with same-ability peers (homogeneously) or different-ability peers (heterogeneously). In fact, there appears to be no empirical evidence that either homogeneous or heterogeneous student matching has any direct effect on writing performance.…

Gifted pupils differ from their age-mates with respect to development potential, actual competencies, self-regulatory capabilities, and learning styles in one or more domains of competence. The question is how to design and develop education that fits and further supports such characteristics and competencies of gifted pupils. Analysis of various…

Studied reference processes in within-class grouping for elementary school students in the Netherlands in homogeneous (n=16) and heterogeneous (n=14) classes. Findings indicate that homogeneous grouping sets strong reference processes in motion, and processes of comparison have considerably greater effects in homogeneous groups, with negative…

One of a series of reports on the International Project for the Evaluation of Educational Achievement (in Mathematics).

Maintains that current research suggests that heterogeneous grouping is preferable. Reports on a study of a new mathematics curriculum using 600 students in 6 Dutch schools. Finds that students in heterogeneous classes taught with cooperative-learning techniques achieved more than students in traditional ability-grouped classrooms. (CFR)

At the end of the 1992-93 school year, Dutch schools finished their preparations for a new core curriculum for the first stage of secondary education. One of the problems teachers faced in implementing this curriculum was the problem of class heterogeneity. How teachers dealt with heterogeneity was studied through an examination of the use of…

Research questions addressed were: (1) Do homogeneous rejected groups of children score higher on antisocial behavior and aggression than mixed-status groups? (2) Are rejected children less antisocial and aggressive when playing with same-status peers than with other-status peers? (3) Are rejected children as disliked for being aggressive in…

This study investigated the effects of classroom composition on achievement. The analysis focused on the assessment of classroom homogeneity with respect to the socioeconomic background and general intelligence of the students. In addition, the extent to which classroom composition affects the standards the teachers employ and how these standards…
