The present study cross-sectionally investigated proportional reasoning abilities in 5- to 9-year-old children (n = 185) before they received instruction in proportional reasoning. This study addressed two important aspects of the development of proportional reasoning that remain unclear in the current literature: (1) the age range in which it…

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…

Cognitive development of eighth-grade students, as identified by Jean Piaget, occurs during a time when many of them are transitioning between concrete operations and formal operations where the ability to think in abstract concepts becomes possible. Because of this period of transition, many eighth-grade students find difficulty in demonstrating…

This article reasserts the centrality of reasoning as the focus for moral education. Attention to moral cognition must be extended to incorporate sociogenetic processes in moral growth. Moral education is not simply growth within the moral domain, but addresses capacities of students to engage in cross-domain coordination. Development beyond…

Five arguments are presented as to the inappropriateness of Piaget's "stage of formal operations" as the final stage of cognitive development. (MJB)

Explores the hypothesis that there is a decline in operational thought ability in the elderly. Two samples of elderly males, with mean ages of 71.80 and 74.29 years respectively, were tested for their ability to conserve mass, surface areas and volume. (BD)

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)

Seven-year-olds and university students were questioned about hidden or visible colored counters. Under certain testing conditions, the children were able to demonstrate one of the major characteristics of formal operational thought, namely the ability to reason in terms of verbally stated hypotheses without reliance on direct, physical…

Contending that mathematical representation sustains a resemblance to the representational activity preceeding it and that it is this analogical resemblance that makes the developmental sequence of children's representational ability visible as a sequence, this paper explores the application of this notion to an undergraduate class in early…

Presents the idea that playwrites adapting plays for children often simplify it so extensively that they do not serve the developmental needs of the child or the artistic conception of the play. Suggests that developing a thematic point of view for the play would help playwrites create fuller characters that are still understandable and enjoyable…

Piaget's theory of cognitive developmental levels is criticized on the grounds that it blends empirical and philosophical issues of knowledge and, therefore, confuses genetic psychology and epistemology. (JN)

In response to the previous article, Whitehurst defends his article on imitation; it is different from Beilin's structural terms, and significant because much is known about imitation. Zimmerman challenges Beilin's interpretation of Piaget's structural assumptions. Brody maintains that children's qualitative changes in moral reasoning are best…

This study examined above-grade-level abstract reasoning abilities of 150 students (grades 2-6). Understanding of abstract concepts varied by age for only four of eight subscales or concepts: probability, proportion, momentum, and frames of reference. Performance varied widely within age level for the understanding of volume, correlation,…

Studies exploring the transition from early to middle adolescence have found a significant increase in formal-operational thinking, but it is questionable whether the typical adolescent is capable of consistently applying formal operational logic. To examine the relationship between Piagetian-based training techniques and formal-operational…

A survey of undergraduate education methods texts indicates that students are repeatedly exposed to the theories of Jean Piaget, with an emphasis on the stages of development and characteristics of preschool children. The suggestion is made that an evaluation should be undertaken of misconceptions that undergraduate students might develop as a…
