The perceptions of students who study environmental science related to pollution are certainly different because they are influenced by various circumstances. These circumstances, among others, depend on what they observe around them and their prior knowledge. This study aimed to determine the concept of pollution according to the cognitive…

Knowledge-in-Use, i.e., the ability to apply what one has learned, is a major goal of education and involves the ability to transfer one's knowledge. While some general principles of knowledge transfer have been revealed, the literature is full of inconclusive results and it remains hard to predict successful transfer. However, research into…

Conceptual change theories assume that knowledge structures grow during the learning process but also get reorganized. Yet, this reorganization process itself is hard to examine. By using concept maps, we examined the changes in students' knowledge structures and linked it to conceptual change theory. In a longitudinal study, thirty high-achieving…

Examines third year university physics students' use of models when explaining familiar phenomena involving interaction between metals and electromagnetic radiation. Concludes that few students use a single model consistently. (Contains 27 references.) (DDR)

Presents a series of standard demonstrations as examples of activities that can be used to introduce multiple concepts and tie different sections of an introductory physics course together. Contributes to changes in classroom dynamics by stimulating student engagement and encouraging inclusivity. (Contains 23 references.) (DDR)

Randomly selected high school students (n=13) who studied an ecology unit were interviewed, and narrative data analyzed for changes in knowledge schema. Data support the current theory that the amount and quality of prior knowledge substantially influence gains in new knowledge and are closely linked to a capacity to apply higher-order cognitive…

Identifies middle school and college students' prior ideas about electrostatic induction. Presented students with observational evidence that supported or refuted their own prior ideas in an interview format. Concludes that the Lakatosian rather than the Popperian view is more acceptable in understanding students' responses to conflicting…

Explores whether construction of integrated knowledge structures by students can be stimulated by concept mapping and better visualization of concepts and their interrelationships. Significant effects of concept mapping as an instructional method could not be detected. (Contains 18 references.) (DDR)

The focus of this study was to portray the ideas that students with four years experience in learning physics developed in regard to the second law of thermodynamics. Data were obtained through 34 clinical interviews with grade 10 students. An analysis of student arguments revealed deeply rooted difficulties in using concepts that were learned in…

The premise behind the cognitive approach to teaching is that understanding results when new learning is integrated with existing knowledge. But the goal of science instruction is to replace existing ideas with new theories. Current research in science education seeks to resolve these conflicting instructional approaches. (Author/VM)

Examined the effects of an instructional method used to remedy students' difficulties caused by fragmented and incorrectly interpreted knowledge. Described the method using explicit concept-interpretation procedures. Finds that the method helped to revise students' deficient prior knowledge about acceleration, and helped them to interpret it…

Speculates about reasons for the lack of use of concept mapping as an instructional strategy. Concludes that the two main barriers to its extensive adoption are the epistemological beliefs of classroom teachers and the underlying philosophy of the curriculum. (Contains 45 references.) (DDR)

Fifty-three elementary school children were tested on Incidental Science Knowledge, i.e., knowledge acquired by chance outside school, and the results obtained were correlated with intellectual development and cognitive style as measured by interviews and group testing, respectively. Indicates that cognitive style and misconception play a…
