It is urgent that we re-examine models of knowledge and knowledge-making within the university, at this time of open learning and deregulated multi-million dollar and euro open science hubs and portals. For otherwise, we are bound into "crude" instrumentalism, "delivering" "knowledge packets" rather than seeing our…

The consideration of threshold concepts is offered in the context of biological education as a theoretical framework that may have utility in the teaching and learning of biology at all levels. Threshold concepts may provide a mechanism to explain the observed punctuated nature of conceptual change. This perspective raises the profile of periods…

Investigates how situational knowledge differs across individuals of different competence levels. Analyzes participants' descriptions of physics problem situations. Discusses the relationship between competence and the structure of problem situations, differences between experts and novices, and implications for teaching. (Author/KHR)

During the last 10 years, cognitive science researchers have produced research findings that have great potential for increasing students' understanding of science. However, commercial publishers continue to produce textbooks and teacher's guides in traditional ways. This project developed a prototype unit which used an alternative approach to…

Describes five astronomy education projects implemented by the Harvard-Smithsonian Center for Astrophysics Science Education Department and funded by the National Science Foundation. Project efforts have concentrated in three major areas: (1) curriculum development; (2) teacher support; and (3) classroom technology. (DDR)

Explores what kinds of calculus-related insights seem to typify calculus-related reasoning. Introduces "qualitative calculus" in which learning is focused on synthesis. Discusses the resemblance and difference between traditional calculus and qualitative calculus, advantages of learning qualitative calculus, and how understanding qualitative…

Secondary school geometry students have been found to have misconceptions concerning parallel lines. Correctional teaching programs did not seem effective in changing these misconceptions. This research describes an attempt to use teaching strategies which take into account current learning theory and which encourages students to be actively…

Examined are two aspects of science education--the nature of science and curriculum reform. Contemporary views on the tentative nature of science and a generative model of learning are synthesized. (KR)

One of the most common misconceptions about probability is the belief that successive outcomes of a random process are not independent. This belief has been dubbed the "gambler's fallacy". The belief that non-normative expectations such as the gambler's fallacy are widely held has inspired probability and statistics instruction that attempts to…

Instructional implications of cognitive development theory are discussed, and it is proposed that the current theoretical framework offers a view of development that, applied in instructional contexts, leads to a reconceptualization of the traditional notion of developmental curricula. Piaget's theory offered a framework for how children should be…

Advances in cognitive science have greatly increased our knowledge of how the human mind stores and uses information. That knowledge can be used to decompose curricular objectives so as to increase the specificity of instruction to a level of precision that should greatly enhance student writing. This article identifies some major types of…

Outlines the use of concept maps as a tool for science curriculum development and discusses the changes that occur in the teacher's view of the curriculum with successive revisions of the maps. Describes and analyzes the maps created by sixth-grade teachers. (PR)

Provides a framework for observing and supporting the development of students as constructivist teachers, especially during their field placements as student teachers. The instructional shift to a constructivist approach is described, and guiding principles and possible indicators of the constructivist model are presented. (SLD)
