Although there was an increase in the proportion of students using the logical principle of exclusion" from grades 7 to 9 to 12, there was little relationship with IQ and socio-economic measures. (AL)

Discusses Novak's views that Ausubel's meaningful learning can become an alternative to Piagetian psychology and argues that Ausubel does not provide a theory that can be an alternative to Piaget's developmental psychology. (HM)

Presents a descriptive analogy comparing Piaget's theory of intellectual development to the development of athletic abilities in order to provide insight into Piagetian theory. (SL)

This study examines the effectiveness exercises based on the cognitive conflict, existing within the child, between two representational systems related to temperature: the qualitative-verbal one and the quantitative-numerical one as these relate to the advancement of children's understanding of the concept of temperature. (Author/DS)

Investigates the effects of high school chemistry experiences on the use of Piaget's operative structures. Reports that students who took chemistry scored higher than those who did not on a test of Piaget's operative comprehension. (GA)

Examined relation between college students' (N=108) ability to solve simple ratio tasks (for example, their proportional reasoning patterns) and their rule-governed behavior with the balance beam. Also identified modifications in a set of rules for the balance beam tasks. Results and implications for science instruction are discussed. (JN)

Many science curriculum development projects have the goal of increasing students' ability to employ scientific or formal reasoning strategies. Argues that longitudinal data of students who acquired formal reasoning strategies as a consequence of specific instruction are needed to provide evidence that these skills will help in other academic…

Discusses the use of the clinical interview in assessing cognitive structure and in investigating conceptual change. They caution much more work is needed to increase the applicability and validity of the clinical interview method and point out that there is a lack of systematization in the analysis of interview transcripts. (Author/PB)

Analyzes the meaning of Piaget's concept of abstraction and provides discussion of some of its shortcomings. (HM)

The methodological issue of qualitative versus quantitative research is addressed, and the argumentation of research using interview methods for research is explored. Warrants of the type that are used in arguments generating conclusions from interview data are included. (KR)

Discusses and refutes Novak's arguments against Piaget's theory of intellectual development in favor of Ausubel's theory of meaningful verbal learning. (GA)

Cites research findings to refute Piaget's contention of stages of cognitive development. Advocates continuous cognitive differentiation as a model. (CP)

Investigated whether instructing children in the component skills underlying Piagetian transitivity tasks would increase their performance on both transitivity-related tasks and on reasoning tasks not directly related to transitivity. Results indicate that incorporating the quantification of certain abstract symbols, training can influence…

Describes grade 9 student responses to instructional materials constructed on objectives derived from Piaget's balance and inclined place problems. Concludes the presence of a hierarchy only in the balance objectives. Indicates implications worthy of further studies. (CC)

The author examines Novak's position that science and mathematics educators should discard Piaget's theory of intellectual development in favor of Ausubel's theory of meaningful learning as a guide for teaching practice and research. (PB)
