The impulse to investigate the natural world is deeply rooted in our earliest childhood experiences. This notion has long guided researchers to uncover the cognitive mechanisms underlying the development of scientific reasoning in children. Until recently, however, research in cognitive development and education followed largely independent…

There is no agreement about the robustness of intuitive representations of the circulatory system and their susceptibility to change by instruction. In this paper, we analyse to what extent students with varying degrees of biology instruction and different ages (High School Health Science and Social Science students and first and final year…

Considered are two commonly used techniques, the interview and word association techniques. Highlighted is a third technique called the repertory grid. This third technique can be used to interpret students' knowledge based on an explicit, psychological theory of human behavior. (Author/CW)

The science learning cycle developed by Robert Karplus and others in the 1960's has been a useful model for many science teachers and researchers. This model stresses the use of structured inquiry to organize knowledge acquisition and problem solving. Recent research in the cognitive science tradition, however, has shown that learning and problem…

This paper summarizes the recent work of the Maryland Physics Education Research Group on analyzing student learning in introductory university physics. This work is carried out in a model of student thinking and learning based on principles from cognitive science. The model permits a better understanding of, and diagnosis for, the state of both…

Differences in the status of ontological categories on the concept maps of secondary-, undergraduate- and graduate-level chemistry students were analyzed with the "Pathfinder" scaling algorithm and multidimensional scaling. Results indicate differences among groups in the structural significance of abstract process-related nodes and…

This study presents a quantitative method for scoring concept maps generated by students learning introductory college chemistry. Concept maps measure the amount of chemical information the student possesses, reasoning ability in chemistry, and specific misconceptions about introductory and physical chemistry concepts. They provide a visualization…

Argues that verbal and non-verbal cues initiated by science teachers affect students' willingness to explore their own ideas. States that changes in such teacher behaviors are necessary before the conceptual changes sought in science education can occur. (AEM)

Specific modes of formal reasoning and measurements of principled moral reasoning ability were obtained from 99 10th-grade students. Hierarchical relationships were found amoung variables with combinatorial and correlational reasoning accounting for 22 percent of the variance in principled moral reasoning. Theoretical and educational implications…

The purpose of this study was to develop a procedure for the evaluation of M-demand of chemistry problems. It was shown that dimensional analysis upon the Neo-Piagetian theory of Pascual-Leone could help science teachers to understand the epistemological basis of their discipline. (CW)

The development of children's causal knowledge is investigated by analyzing changes in the content and form of the explanations they generate across the age span of three to nine years. The balance of incremental versus fundamental change and the forms each takes in children coming to understand the working of gears are examined. Three phases of…

During the past 15 years, physics education research has revealed many surprising things about the difficulties introductory physics students have in learning physics. At the same time, the ongoing revolution in information technology has led to new tools for creating innovative educational environments. In response to these two developments, a…

Reports a study which identified different problem-solving strategies among Hong Kong high school chemistry students. Finds that student experts employed a recognition plus a working forwards strategy, whereas student novices attempted a means-end analysis to create a solution procedure. Comparisons were made with problem-solving in physics. (GG)

Discussed is the relationship of concept-mapping by students to the meaningful learning of genetics and ecological concepts. The implications of these results for teacher education in biology are addressed. (KR)

Discusses theories of how children represent the environment in their memory with reference to recent empirical evidence. States that children are more competent at recalling a route than has been assumed previously and that there are age-related differences in children's ability to select landmarks along a route.
