Morrison, Judith A.; Lederman, Norman G. – Science Education, 2003
Research has established that students enter their science classes with ideas about the natural world that do not align with accepted scientific beliefs. The diagnosis of these student preconceptions may be seen as an initial, crucial step in the process of teacher-facilitated conceptual change. So as to capture what science teachers do in their…

Snir, Joseph; Smith, Carol L.; Raz, Gila – Science Education, 2003
Helping students understand the general nature of scientific models is increasingly regarded as an important goal of the middle and high school science curriculum (e.g., J. K. Gilbert & C. Boutler, 1998. "International Handbook of Science Education"; Kluwer, London; A. G. Harrison & D. F. Treagust, 2000. "Science Education," 352-381). In addition,…

Taber, Keith S. – Science Education, 2003
This paper describes the conceptualizations, or mental models, of the nature of the bonding and structure of metals of a group of U.K. college students. It is suggested that these mental models may be understood in terms of the students' prior learning about covalent and ionic bonding, and the prevalence of a common alternative conceptual…

Kurth, Lori A.; Anderson, Charles W.; Palincsar, Annemarie S. – Science Education, 2002
Explains the story of four sixth-grade students, of mixed race and social class, who worked together in a small group experimenting with colored solutions with different densities. Describes students' failures in achieving intersubjective communication using the sociolinguistic concepts of polysemy and privileging. (Contains 41 references.)…

Shipman, Harry L.; Brickhouse, Nancy W.; Dagher, Zoubeida; Letts, William J., IV – Science Education, 2002
A cautious introduction of the dialogue between science and religion into a college astronomy course provoked diverse reactions from the 340 students in the course. Reports that approximately half of the students in the class engaged with the issue of science and religion to some extent and that there were few negative reactions to this…

Boo, Hong-Kwen; Watson, J. R. – Science Education, 2001
Explores the development over time of students' understandings of the concept of chemical reaction in the context of two familiar reactions in solution. Based on interviews (n=48), results show that students made some progress in their understanding of the concept of chemical reaction but some fundamental misconceptions remained. (Author/MM)

Stuck, Gary B.; Wyne, Marvin D. – Science Education, 1970
Experiment compares the effect of equilibration type training to the effects of S-R reinforcement type training in developing weight-conservation concepts in second and third grade pupils. S-R group performed significantly better than control group on initial posttest for conservation of weight. A measure for permanence of the conservation beliefs…

Palmer, David H. – Science Education, 1999
Describes a study that investigated whether scientific and nonscientific understandings in the same content area are linked. Finds that students' (n=107) explanations indicate that they were using an "if-then" type of reasoning which linked scientific and nonscientific conceptions. Contains 39 references. (Author/WRM)

Bezzi, Alfredo – Science Education, 1999
Investigates conceptions of the geosciences held by a university geology instructor and five students before and after a teaching intervention. Argues for the use of repertory grids to elicit personal constructs. Advocates targeting the societal aims of geological education within a constructivist framework. Contains 54 references.
