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)

Two experiments investigated the relationship between family size and "theory of mind." Results from an experiment with three- and four-year olds showed that children from larger families were better able than children from smaller families to predict a story character's mistaken (false-belief based) action. (MDM)

An investigation of students understandings of acids and bases using concept maps, multiple-choice tests, and clinical interviews is described. The methodology and resulting analysis are illustrated with two abbreviated case studies selected from the study. Discussion of concept mapping points to how it starkly represents gaps in the understanding…

The conceptual frameworks of Thai children (n=48) related to causes of health and sickness were analyzed using the "Interview-about-Instances" and the "Conceptual Profile Inventory" techniques. The results indicate that Thai schoolchildren hold considerable personal knowledge about the causes of health and sickness that does…

Literacy should not be limited to decoding written text. More broadly construed, education should address the many ways in which experience is represented, the development of cognitive potential, and differences in intellectual proclivities. The object should be cultivation of a broad capacity to construct meaning. (SK)

The conceptual views of homeostasis held by students (n=300) in seventh grade life science, tenth grade biology, and college zoology were examined. A biographical questionnaire, the results from two Piagetian-like developmental tasks, and a concept evaluation statement of homeostasis were collected from each student. Understanding of the concept…

Based on a two-tiered epistemological model (preliminary physical concepts and emerging mathematical concepts), studied the construction of number among 91 kindergarten students in France, Canada, and the United States. Subjects' cognitive numerical structures were surprisingly similar despite differences in language and culture. (SV)

Analyzing the paradigmatic shift from Peripatetic to Galilean physics can help to understand students' difficulties in learning Newtonian mechanics. Promotes the use of historical texts in physics teaching as a means to support students in becoming aware of the structural differences between everyday life and scientific views of the world.

Maintains that certain concepts in mathematics are difficult to learn because of problematic continuity from prior knowledge to new concepts. Focuses on the problems of conceptual change connected with the learning of calculus and the shift from rational to real numbers. Summarizes the results of a study involving secondary students. (MJP)

Studies the co-emergence of teaching and children's construction of specific conceptions that support the generation of improper fractions in a constructivist teaching experiment with two fourth-grade students posing and solving tasks in a computer microworld. Reports that examination of the teacher's adaptation of learning situations (tasks) and…

Urges "watering up" the curriculum for adolescents with learning disabilities and identifies principles associated with making knowledge construction more meaningful. Offered are specific instructional techniques for use in inclusive settings, such as focusing on teaching big ideas, promoting elaboration, relating to real-world contexts, and…

Responds to Needham and Baillargeon's criticisms and offers an alternative resolution of the conflicting results between the laboratories regarding abilities of infants less than 12 months to use property/featural information for object individuation. Maintains that kind concepts are acquired as infants approach their first birthday and that…

Advocates artificial neural networks as models for cognition and development. Provides an example of how such models work in the context of a well-known Piagetian developmental task and school science activity: balance beam problems. (Contains 59 references.) (Author/WRM)

The purpose of this study was to examine how 3-dimensional (3-D) models of the Solar System supported student development of conceptual understandings of various astronomical phenomena that required a change in frame of reference. In the course described in this study, students worked in teams to design and construct 3-D virtual reality computer…

Hypermedia as a learning environment complements traditional instruction as it places the student at a higher level of control. Instead of "wait and see" what the teacher expects the student to learn next, hypermedia stimulates the student to become aware of his/her own cognitive needs and interests. This paper presents a combination of notions…
