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…

The present study aimed to identify the stage of thinking of practicum students at Najran University in light of Piaget's theory and its relationship to their academic achievement in the scientific disciplines they were studying at the college of science, mainly mathematics, physics and chemistry disciplines. The sample consisted of (50) female…

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…

The origins and development of our geometric intuitions have been debated for millennia. The present study links children's developing intuitions about the properties of planar triangles to their developing abilities to read purely geometric maps. Six-year-old children are limited when navigating by maps that depict only the sides of a triangle in…

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…

The study was conducted to assess the moral reasoning of adolescent boys and girls in the light of Gilligan theory. The main objectives of the study were to investigate the moral reasoning of adolescent boys and girls with reference to responsibility orientation versus justice orientation and to compare the frequency of adolescent boys and girls…

The purpose of this study was to examine how moral reasoning develops for 236 students enrolled in either a diversity course or a management course. These courses were compared based on the level of diversity inclusion and type of pedagogy employed in the classroom. We used causal modelling to compare the two types of courses, controlling for the…

The present studies investigated children's and adults' intuitive beliefs about the physical nature of essences. Adults and children (ranging in age from 6 to 10 years old) were asked to reason about 2 different ways of determining an unknown object's category: taking a tiny internal sample from any part of the object (distributed view of essence)…

The study was designed to test the hierarchy of difficulty in the acquisition of principles of class and conditional logic for 120 children of normal intelligence, and to compare the relative rates of logic development for those children of normal intelligence with the rate of logic development found in a previous study involving 120 gifted…

This study attempted to clarify the developmental progression in the understanding of conditional sentences by evaluating the capacity of 71 third, 70 sixth, and 64 ninth graders to learn three interpretations of abstract conditional sentences. (JMB)

The study examined whether learning disabled students differed in development of proportional reasoning and whether their disability was in the use of symbols and language rather than ability to solve proportional problems. Developmental scalograms supported the hypothesis that LD Ss' proportional reasoning abilities are developmental, not unlike…

Assesses five- and 10-year-old children's understanding of second-order belief structures in acted stories in which two characters were independently informed about an object's unexpected transfer to a new location. Results show unexpected early competence around age six or seven under optimal conditions when inference of second-order beliefs is…

One hundred and sixty gifted children (4-11 years old) participated in a study confirming a hierarchy of difficulties for logic activities and the existence of a developmental trend in logic learning. (CL)

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