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…

Drawing upon the Search for Ideas in Associative Memory (SIAM) model as the theoretical framework, the impact of heterogeneity and topic relevance of visual stimuli on ideation performance was examined. Results from a laboratory experiment showed that visual stimuli increased productivity and diversity of idea generation, that relevance to the…

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…

The objective of this paper is to measure the efficiency of high schools in Tunisia. We use a statistical data envelopment analysis (DEA)-bootstrap approach with quasi-fixed inputs to estimate the precision of our measure. To do so, we developed a statistical model serving as the foundation of the data generation process (DGP). The DGP is…

A theoretical model of the relationship between class size and achievement is proposed, based on the assumption that a teacher adjusts the style and pace of a lesson to the least able student. The model accounts for features of the Glass and Smith meta-analysis of research. (Author/MT)

This paper discusses the use of student groups in formal education. A model is proposed which involves the development of student interdependence on common tasks, the use of group incentives which may be earned through competition with a standard or with other groups, and the exchange of student resources in teaching and learning. In contrast to…

Discussion of industrial-educational cooperation focuses on the Learning Curve model, which can be used to evaluate the cost effectiveness of learning programs. Cost effectiveness for homogeneous and heterogeneous groups is discussed, and the use of computers to gather information about learning achievement is considered. (Six references) (LRW)

Effects of student grouping on academic achievement were examined in research among high school students in Israeli kibbutz schools, and in a nationwide sample of middle school students in Israel. Data analysis was based on a model developed from research findings in the United States, Sweden, Great Britain, and Israel. The treatment variable was…

This chapter reviews recent trends toward increasing emphasis on excellence in American business and applies these trends to school reform and restructuring in the context of gifted education.
