Piaget's theory of stage structure is synonymous with discussions involving cognitive development. As with any theoretical model, researchers inevitably and rightly seek to affirm and/or contest the elements of the model presented. In this comparative study, students' performance across three hands-on engineering tasks for two distinct student…

A good deal of research purports that bilingualism has a positive effect on some aspects of cognitive functioning. However, this effect is not consistent, and little research examines trajectories of cognitive skill development in bilingual children. Moreover, it remains unclear whether different types of bilingualism impact how cognitive…

According to Lev S. Vygotsky (1896-1934), the highest levels of abstract thinking and self-regulation in preschool development are established in "pretend play using object substitutions." An extensive research literature supports Vygotsky's empirical model of the internalization of self-guiding speech (social speech > private speech…

The present study was a causality study that investigate the effects of conditional factors; if x, y & z are the independent factors (e.g. socio-economic status, Anthropometric status, and home environmental status) on the dependent factors (e.g. memory, social skill, language acquisition, logical reasoning, and problem solving). The present…

This research examined the effectiveness of Multipurpose Unit Early Classroom Intervention Program (MUECIP) prepared for 4-5-year-old (48-60 months) children whose development is at risk because of their families' socioeconomic conditions. The research adopted a preliminary test-final test control group trial model. The research participants were…

A total of 192 second- to sixth-grade children, showing three different levels of class-inclusion answers (failure, correct answer based on counting, correct answer based on logical reasons), performed four necessity tasks. Results are discussed with reference to individual and constructive generalization processes. (Author/RH)

Sixty Japanese children ranging in age from 3 years 4 months to 7 years 5 months were individually interviewed with three Piagetian tasks. Children's levels of representation were assessed by asking for a graphic representation of 4 dishes, 6 pencils, 8 small blocks etc. A conservation-of-number task was then given to assess children's level of…

The aims of this study were (1) to test the dyadic superiority hypothesis by comparing dyadic performance on a logical reasoning task with the performance of children working alone, and (2) to determine whether the incorrect child's compliance with the correct child was a major factor in the dyadic production of correct answers. (Author/DB)

Interviews 60 Japanese children between the ages of 3 and 7 years to investigate the relationship between levels of abstraction and representation. Indicates that abstraction and representation are closely related. Implies that educators need to focus more on the mental relationships children make because the meaning children can give to…

Described are how students (n=2,000) reduce the complexity of multivariable problems. Tendencies toward "functional reduction" in common reasoning are shown to range from a simple reduction in the number of variables considered, to a more elaborate procedure where all variables are taken into account, but in a simplified way involving…

Examined children's ability to settle causal relations and their capacity to make conclusions based on certain experiences and representations. Found that preschool children have a solid explanatory basis for their everyday life, within which facts are not generally accepted but are interpreted through a certain "logic," and the motives…

The study examined methods of mathematical problem solving with 34 gifted and 34 average Dutch 10 year olds. Typical questioning protocols are diagrammed and results tabulated. Preliminary findings suggest the potential value of explicit teaching of advanced mathematical problem-solving skills to pupils of average ability. (DB)

Observation of practices in V. V. Davydov's laboratory school suggests that students proceed from concrete example to abstract generalization--rather than from abstract to concrete, as Davydov has claimed. (GDC)

Discusses geometrical reasoning in the framework of the theory of Figural Concepts to highlight the interaction between the figural and conceptual components of geometrical concepts. Examples of students' difficulties and errors in geometrical reasoning are interpreted according to the internal tension that appears in figural concepts resulting…

This study reports on the historical conceptualization among Finnish 12-13 year-olds who were given a projective task to yield historical thinking. The case study examines expressions the subjects used and which were studied qualitatively, using "chunks of meaning" as units of analysis, in regard to both their meaning- content and their…
