Both scientists and children make important structural discoveries, yet their computational underpinnings are not well understood. Structure discovery has previously been formalized as probabilistic inference about the right structural form--where form could be a tree, ring, chain, grid, etc. (Kemp & Tenenbaum, 2008). Although this approach…

Radical constructivists advocate discovery-based pedagogical regimes that enable students to incrementally and continuously adapt their cognitive structures to the instrumented cultural environment. Some sociocultural theorists, however, maintain that learning implies discontinuity in conceptual development, because novices must appropriate expert…

The impulse to investigate the natural world is deeply rooted in our earliest childhood experiences. This notion has long guided researchers to uncover the cognitive mechanisms underlying the development of scientific reasoning in children. Until recently, however, research in cognitive development and education followed largely independent…

Explains the philosophy that forms the basis of a high school physical science course based on astronomy and the activity-based textbook that accompanies it. Cites specific examples of misconceptions related to astronomy and recommends various diagnostic and concept change strategies. (DDR)

Describes five astronomy education projects implemented by the Harvard-Smithsonian Center for Astrophysics Science Education Department and funded by the National Science Foundation. Project efforts have concentrated in three major areas: (1) curriculum development; (2) teacher support; and (3) classroom technology. (DDR)

Reviews research on (1) schemata acquisition while learning mathematics and techniques for detecting schema in mathematics learners; and (2) assessment of the distribution of cognitive resources while learning mathematics that lead to the design of instructional techniques to facilitate schema acquisition.

Discusses Vee mapping, a technique to assist students in categorizing the relationship between the conceptual and procedural aspects of science. Presents a study to investigate elementary education majors' (n=27) use of the Vee heuristic and concept mapping for the construction of knowledge; attitudes toward learning science in collaborative…

Maintains that student-centered curriculum embodies the progressive and constructivist principles of active, participatory learning. Advocates emphasizing the importance of context as part of a constructivist approach. Includes instructional examples of connecting contextual information about artworks to constructivist activities.
