These longitudinal studies investigated the cultural mediation of children's thinking about the Earth using an interview technique designed to elicit responses from children from all "levels" of their conceptual organization (intuitive, cultural, and scientific). Close scrutiny of the research literature in this field reveals that some…

Considers substance identity and pupils' interaction with the scientific idea of melting and boiling behavior as a means for identification and assessment of purity. Presents evidence that suggests that children do not naturally have a concept of substance identity that allows them to recognize chemical change as a possibility. (Contains 31…

Examined college students' logical reasoning ability using the Test of Logical Thinking (TOLT) as a major predictor of science acheivement. Reports an improvement on each of the subscale scores, and a significant correlation with four science subjects on both pre- and post-TOLT scores. (YP)

Analysis of data on children's ideas about seeing and light is reported. Analysis is theoretically informed by Piagetian stage theory of genetic epistemology. Data produced by other researchers have been recoded to enable quantitative comparisons to be made with the survey data reported by Shayer and Adey (1981). Patterns in the data exposed by…

Reports the existence of patterns of reasoning that are common to students' conceptions in different areas of mechanics. Finds that the common frameworks between different ideas have a generality level that lies between Piaget's stage theory and the approach of alternative conceptions. Contains 30 references. (Author/WRM)

Addresses some criticisms of the Cognitive Acceleration through Science Education (CASE) project. Offers a different description of the CASE teaching method and presents evidence from the program. Contains 20 references. (Author/WRM)

Attempts to find connections and bridges between social constructivism and Piagetian constructivism so that both may be enriched, to the benefit of science teaching. (Contains 95 references.) (Author/WRM)

Discusses the possibilities of accelerating the rate of cognitive development and describes the design and trial of intervention lessons. Gives preliminary results from one laboratory school indicating that the possibility of accelerating general cognitive development is worth pursuing. (YP)

The development of children's cosmologies was investigated over a 13-year period, using multi-modal, in-depth interviews with 686 children (217 boys, 227 girls from New Zealand and 129 boys, 113 girls from China), aged 2-18. Children were interviewed while they "observed" the apparent motion of the Sun and Moon, and other features of the…

Examines whether participation in physical experiments together with social interaction with adults and school-mates favor the development of causal knowledge and the understanding of a complex physical subject. Concludes that the treatments can lead students to give up pre-causal explanations and to resort to physical ones. (Author/YP)

Investigates the development of dynamics concepts with one group aged 12-14, and other group aged 14-16. Collects data from Assessment of Performance in Science tasks, Piagetian tasks, and classroom science curriculum. Discusses the interaction of cognitive development and classroom experience in the development of concepts. (Author/YP)
