Describes research project being implemented in the United Kingdom that has been developed to examine the process of change in secondary school students' conceptual understandings in the physical sciences. Models of conceptual change are described, the role of computer based activities in promoting conceptual change is discussed, and software…

How students restructured their scientific ideas in response to contradictions was studied with 166 male and female students (aged 12 to 14 years) who tested their predictions about water displacement by experiment. Conceptual change varied; all subjects tended to hold onto old ideas, even when presented with conflicting information. (SLD)

Examined the evolution of the knowledge and the notions of students in order to see how after one year of university study their concepts and ideas of scientific theory in chemistry had progressed. Reports that sometimes the students' conceptions are modified in the wrong way. (Author/YP)

Examined 8- and 10-year olds' understanding of the unique features of and potential relations among mental activities. Found a developing tendency to organize mental activities on the degree to which memory was a component of the activity. Results suggest that a constructivist theory of mind develops in later childhood. (AA)

Observations and interviews with (n=16) undergraduate mathematics and mathematics education majors learning to do formal mathematical proofs found three major sources of students' difficulties: concept understanding, mathematical language and notation, and getting started on a proof. (25 references) (MKR)

Describes observations, written samples, and interviews of (n=24) high school teachers learning concepts of group, subgroup, coset, normality, and quotient group in an Abstract Algebra course. General observations are made about the role of errors and misconceptions in light of an action-process-schema framework. (32 references) (MKR)

A study of (n=26) prospective elementary teachers' understanding of the area of a rectangular region as a multiplicative relationship between the lengths of the sides resulted in the development of a description of the quantitative reasoning involved. (23 references) (MKR)

Evaluated the effects of cooperative learning on students' (n=36) verbal interaction patterns and achievement in a conceptual change instructional model in secondary science. It was found that students using cooperative-learning strategies showed greater achievement gains and made greater use of specific verbal patterns believed to be related to…

Discusses the interactions between technology and research in mathematics education, including computer-assisted instruction, role of technology in learning, use of computer environments to study students' mathematical concept formation, research methodologies, interactive technologies, and lack of technology-related research in the "Journal…

Provides an account of how three elementary school teachers, two in Australia and one in the United States, used multimedia to enhance student learning. Topics include a historical context of trends in school computing, computer-enhanced learning, reflective learning, concept development, cooperative learning, and learning planning skills.…

Describes and discusses an epistemological approach to the education of science teachers that emphasizes similarities in knowledge and modes of acquiring knowledge among children, scientists in their historical contexts, and student teachers. (ZWH)

Analyzes differences in students' performance on algorithmic, lower-order cognitive skills (LOCS), and conceptual exam questions and the correlations between their achievements on these categories across different populations.Reports that the highest scores were obtained for the algorithmic questions, the lowest for the conceptual questions, and…

Describes a computer model characterizing the balance of soil-plant Nitrogen that allows students to see the likely consequences of different biological and weather-related parameters. Proposes three uses for the model: (1) orienting beginning students to understand the soil Nitrogen cycle; (2) providing information for advanced students; and (3)…

Examines analogical reasoning in contexts where understanding is generated from loosely organized, incomplete prior knowledge rather than transferred from a well-structured domain of understanding. Participants, consisting of 11 secondary school science teacher candidates, were presented with a piston/cylinder device and asked to explain the…

Three experiments using university students explored what constitutes an event and what determines its boundaries. Results supported the hypothesis that sequences of stimuli repeating in different contexts are cut out to become cognitive entities ("things" with a beginning and an end) in their own right. Results suggest that the…
