The interdependence between the first and second language of bilingual immigrant children has not received sufficient attention in research. Most studies concentrate on mainstream language skills of immigrant pupils. In some studies, the gaps in the language development of immigrant children are documented by comparing mainstream pupils with…

The relationships between three types of tasks were investigated with 428 children from kindergarten through grade 6 showing that correspondence, seriation, and transitivity reflected different underlying concepts. Thus, it was concluded that neither correspondence nor transitivity tasks can serve as replacements for traditional seriation tasks in…

A case study of the period of repetitive babbling in one Dutch infant is reported. Repetitive babbling is seen as a systematic and continuous process, during which the child is applying certain strategies in order to form concepts concerning the possibilities of his or her articulatory apparatus. Strategies identified are: (1) variation…

Describes two studies investigating the development of recursive thinking in 60 Dutch children five, seven, and nine years of age. The first study replicated earlier research employing a verbal production procedure. The second study used verbal comprehension procedures and concluded that development appears two years earlier than indicated by the…

This study investigated the effects of K. J. Klauer's (1989) inductive reasoning training program of teaching children. Effects of training and the range of transfer of the training were assessed. The subjects were 34 third-grade Dutch children of average ability, matched on age, sex, and IQ. Children from the training condition (N=17) received…

Compares two experimental programs for teaching mental addition and subtraction in the Dutch second grade (N=275). Discusses realistic program design (RPD) and gradual program design (GPD). Concludes that RPD pupils show a more varied use of solution procedures than GPD pupils. Contains 46 references. (Author/ASK)

In this study Dutch subjects with four different levels of expertise (24 second-year, 24 fourth-year, 24 sixth-year medical students, and 24 internists with at least 4 years of experience) studied, diagnosed, and explained four clinical cases. Diagnostic accuracy increased with the increasing level of expertise. The number of concepts used and the…

This paper examines ways in which coherent reasoning about key concepts such as variability, sampling, data, and distribution can be developed as part of statistics education. Instructional activities that could support such reasoning were developed through design research conducted with students in grades 7 and 8. Results are reported from a…

Evaluates the effectiveness of a course using a constructivist approach in reducing Dutch secondary school students (n=190) misconceptions about force. Concluded that the lessons were effective in changing students' ideas in regard to forces in rest situations and frictional forces and that learning effects were equally distributed over student…
