Views of (n=70) 16- and 17-year olds on mathematical knowledge, activity, and learning were analyzed using factorial techniques. Findings suggest there was no simple systematic relationship between beliefs about the nature of mathematical knowledge and the teaching and learning of mathematics. (19 references) (Author/MKR)

Describes a model for generative teaching of comprehension that focuses on students' knowledge base and preconceptions; motivation; attention; and generation of new models and explanations. Generative teaching procedures for facilitating comprehension in elementary school are reported. (Author/LB)

Teaching/learning trends include (1) incremental (information explosion); (2) stationary (biology of cognitive processes); and (3) iterative (recurring debates over teaching methods). Effects are externalization of knowledge structures, the importance of "importance," and instructional "enabling," failure of teachers and students to confront real…

Adolescents with mental retardation viewed a story enacted with props and were asked questions about the knowledge and beliefs of the characters. Subjects performed worse than did nondisabled children matched for mental age. Subjects did better on questions requiring first-order reasoning than on those involving second-order reasoning.

Differences in students' (aged 12-14) construction and analysis of mathematical algorithms may be explained by the differences between predicative and functional cognitive structures. Analyzes the central role of internal and external representations and the characteristics of each. Discusses prototypical research design and development of a…

Examines the nature of prior mathematical knowledge that facilitates the construction of useful problem representations in the domain of geometry. Indicates that high achievers build schemas that are qualitatively more sophisticated than low achievers, which in turn helps them construct representations that are conducive to understanding the…

Explores the relevance of hierarchies to information processing. Suggests that participants in all conditions create hierarchical representations as they work, and those in nonlinear conditions use this structure to guide their exploration of the material. An important function of hierarchies may be to define relationships between concepts.…

Argues for the need for theoretical work on mental models in the field of science education. Considers relationships between both models and theories, and mental models and conceptions in order to improve the notions of "model" and "mental model" used in the literature. Contains 20 references. (Author/WRM)

Explores the successive and progressive changes in the structural complexity and propositional validity of knowledge held by students enrolled in an advanced undergraduate university-level biology course. Finds that in general, a significant amount of weak restructuring occurs and that the most radical type of strong restructuring occurs during…

Used Theory of Reasoned Action to investigate the cognitive structure underlying substance use through interviews with mothers 17 years old or younger during pregnancy. Found that substance use was lowest during pregnancy, increased sharply at 6 months postpartum, and remained level at 12 months. Changes in intentions, attitudes, perceived social…

Examines bioregional mapping as an example of how a different system (educational or otherwise) could be designed through shifting the focus of figure-ground gestalts and revisioning core metaphors. Discusses the notions of community and place, the potential for cognitive restructuring, literal and conceptual maps, and the potential of solving…

Adapted Keil's predictability method to examine adults' and preschoolers' conceptions of numbers, focusing on the ontological distinction between numbers and sets of objects. Found that children, like adults, attribute spatial-arrangement properties to collections much more than to numbers, although both are considered to have quantitative…

Examines the validity of claims that concept maps measure an important aspect of students' knowledge structures. Provides a working definition of concept mapping and a brief theoretical background, characterizes concept maps as a potential assessment in science, reviews empirical evidence on the reliability and validity of various concept mapping…

Skills acquisition is complex and cyclic rather than linear and modular as in competency-based training methods. It depends not only on mental attributes that infuse meaning but also on personality dimensions, learning styles, and self-concerns. This raises ethical questions about policies emphasizing competency-based methods. (SK)

Investigates the effects of Science-Technology-Society instruction on a group of Taiwanese female 10th grade students' cognitive structure outcomes. Examines the role of student scientific epistemological beliefs on such effects. (Author/SAH)
