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…

Estimates confluence model of intellectual development for a within-family sample of 321 children from 101 transracial adoptive families. Mental ages of children and their parents and birth or adoption intervals were used in a nonlinear least-squares estimation procedure to obtain children's predicted mental ages. Results suggest efficiency of the…

Secondary geometry students were tested for van Hiele level of thinking, geometry knowledge and achievement, and proof-writing achievement. Proof-writing achievement correlated significantly with van Hiele level entering geometry knowledge and geometry achievement. The predictive validity of the van Hiele model was supported.

This study examined the science process skill of prediction problem solving using naturalistic research methodology and information-processing theory. The think-aloud interview led to the identification of several specific program exploration and prediction behaviors. A total of 14 high school biology students made predictions concerning the…

Misconceptions, shown to be prevalent in students even at the college level, may affect the cognitive process of making predictions in biology. The purpose of this study was to: (1) identify students' misconceptions about important biological concepts; (2) identify students' cognitive behaviors associated with making predictions about these…

A methodology for confronting students with the inconsistencies entailed by their own beliefs is outlined. This methodology is illustrated using the dynamics domain of physics and a computer modeling program, DYNALAB. (KR)

Misconceptions are systematic, intelligently conceived, and quite reasonable theories that have been constructed on the basis of experience. Research studies on misconceptions have indicated that students develop intelligently conceived and sophisticated concepts of science. Although some of these are compatible with the principles of modern…

Cognitive science research offers hope for the development of innovative science teaching strategies that facilitate the development of optimally interconnected procedural and declarative knowledge networks. Improving students' neural networks should improve their abilities to think critically, reason logically, learn more efficiently, and solve…

Uses test questions from the Basic Economics Test (BET) to reveal that elementary students are capable of understanding economics concepts. Maintains that neither ethnic background nor parental income makes a difference in economic learning. The most statistically significant determinant of improved scores was the extent to which a concept was…
