The link between science education and early childhood education is still blurred. This is so because many science education researchers apparently, but mistakenly, believe that the way young children interrogate and investigate the world around them is not appropriate for their understanding of scientific concepts. Although there is an effort…

Teacher-student discourse continues to be teacher-centred even though researchers and reform documents have recommended changes toward increased levels of student-centred discourse. In science education this situation is paralleled by effort to make scientific inquiry more student-centred. The purpose of this study was to investigate how discourse…

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…

General scientific literacy includes understanding the grounds on which scientific claims are based. The measurements scientists make and the data that they produce from them generally constitute these grounds. However, the nature of data generation has received relatively little attention from those interested in teaching science through inquiry.…

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…

Presents the opportunity to continue and enhance the dialogue about ways to research and understand children's discourse during science activities and inquiry processes by opening a window onto a variety of techniques, methods, and approaches to the analysis of one short discussion between several elementary students.

In education research, a polar distinction is frequently made to describe and produce different kinds of research: "quantitative" versus "qualitative." In this article, the authors argue against that polarization and the associated polarization of the "subjective" and the "objective," and they question the attribution of generalizability to only…

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.…

Reviews two dimensions in which science and technology share fundamental similarities: (a) the production and transformation of representations; and (b) the action-oriented language that describes the two domains. Illustrates what and how students know and learn science during technological design activities. (Contains 66 references.) (Author/YDS)

Reviews some of the student competencies from the National Council of Teachers of Mathematics (NCTM). Argues that these competencies focus on data collection, analysis, and presentation and are easily integrated with science curriculum reform at the same grade levels. Contains 39 references. (DDR)

Investigates the use of mathematical representations in 3 grade-8 general science classes (n=65) that engaged in a 10-week open inquiry about the correlations between biological and physical variables in the environment. Demonstrates the use of representations as conscription devices, and illustrates how the use and understanding of inscriptions…

This male-specific study examined the development of integrated process skill in the context of open-inquiry laboratory sessions. Findings from this qualitative study indicate that male students develop higher-order process skills through nontraditional laboratory experiences that provided the students with freedom to perform experiments of…

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…
