Given the peculiarities of mobile computer-supported collaborative learning (MCSCL) environments, forming suitable groups in such learning environments represents a hard and time-consuming task. This is because many conditions related to mobile learners, devices, and environment should be considered. Unlike the existing solutions, the present…

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…

Considering that group formation is one of the key processes in collaborative learning, the aim of this paper is to propose a method based on a genetic algorithm approach for achieving inter-homogeneous and intra-heterogeneous groups. The main feature of such a method is that it allows for the consideration of as many student characteristics as…

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…

In recent studies, some researchers were eager for the answer of how to group a perfectly dream team. There are various grouping methods, e.g. random assignment, homogeneous grouping with personality or achievement and heterogeneous grouping with personality or achievement, were proposed. Some instructors could put some students in a team better…

TWO EMPIRICAL STUDIES WERE MADE TO TEST THE DESIRABILITY OF EMPLOYING SOME FORM OF ABILITY GROUPING TO ENHANCE LEARNING OPPORTUNITIES IN SCHOOLS. THE TWO FIELD STUDIES SPECIFICALLY EXPLORED SOME OF THE MOTIVATIONAL IMPLICATIONS OF ABILITY GROUPING AS MANIFESTED IN SCHOLASTIC ACHIEVEMENT, REPORTED INTEREST IN SCHOOLWORK, AND THE DEVELOPMENT OF…

Presents a case study of grade 9 curriculum reforms at a urban high school in Ontario (Canada). Explains that students were streamed according to their abilities and interests before the reform. Discusses questions related to de-streaming, especially how teachers contend with mixed-ability classes, and integration with a particular focus on…

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…

ACTIVITIES OF RESEARCH AND INSTRUCTION UNITS IN TWO MANITOWOC, WISCONSIN, ELEMENTARY SCHOOLS DURING THE 1966-67 SCHOOL YEAR ARE REVIEWED. RESULTS OF TWO CONTROLLED EXPERIMENTS CONDUCTED IN THE UNITS ARE REPORTED AND EVALUATED. IN ONE STUDY THE PERFORMANCE OF 82 THIRD GRADE PUPILS FROM ONE SCHOOL HOMOGENEOUSLY GROUPED FOR ARITHMETIC INSTRUCTION WAS…
