Triadic dialogue, the Initiation, Response, Evaluation sequence typical of teacher /student interactions in classrooms, has long been identified as a barrier to students' access to learning, including science learning. A large body of research on the subject has over the years led to projects and policies aimed at increasing opportunities for…

The aim of this study is to advance current understanding of the transactional processes that characterize students' sense-making practices when they are confronted with multiple representations of scientific phenomena. Data for the study are derived from a design experiment that involves a technology-rich, inquiry-based sequence of…

Teachers often have difficulty implementing inquiry-based activities, leading to the arousal of negative emotions. In this multicase study of beginning physics teachers in Australia, we were interested in the extent to which their expectations were realized and how their classroom experiences while implementing extended experimental investigations…

Describes a case study of an expert teacher's questioning strategies during an open-inquiry engineering curriculum in a grade four and five classroom. Analysis provides evidence for the complexity of questioning that is characterized by the interactions of context and content of, and response and reactions to, questions. Contains 45 references.…

Describes the use of Vee maps in helping students understand scientific investigations. (PR)

Reports about U.S. schools have indicated the need for improvement of science teaching and learning. One of the solutions advocated calls for classroom contexts that allow for authentic practice under the guidance of teachers who model pertinent skills as practitioners in the field of study. The metaphor used to describe such teaching-learning…

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…
