New reforms in science education call for three-dimensional learning by integrating disciplinary core ideas, science and engineering practices, and "crosscutting concepts" (CCCs). These reforms defined the new term, crosscutting concept (CCC), as a lens that has explanatory power across disciplines. To describe how researchers are…

The forecast for the first quarter of this century is that the issue of teaching science in the language to which the learner is most familiar will receive more attention in our quest to win more students for science. Over two-thirds of countries in Africa, Asia, and Europe have developed policies on the use of the mother tongue for teaching…

Science educators are confronted with the challenge to accommodate in their classes an increasing cultural and linguistic diversity that results from globalization. Challenged by the call to work towards valuing and keeping this diversity in the face of the canonical nature of school science discourse, we propose a new way of thinking about and…

In 2005 India introduced a new National Curriculum Framework aimed at providing a more constructivist approach to learning for all subjects. Previous research on the impact of curriculum reform in other countries (e.g., United States) concluded that for reform to be successful teachers' orientations toward teaching and learning must be considered…

This study is a meta-interpretative analysis that focuses on research conducted and published by other researchers. Concepts central to this study include global practical relevance, curriculum design, and formative situation. We analyzed 35 studies selected from 374 published studies in the years 2000 and 2001 in three journals referenced in the…

Students' views about science were correlated with their approaches to lab practice. Three distinct cases are discussed in detail: empiricist-oriented, rationalist-oriented, and constructivist-oriented students. A coherent epistemological theory was constructed for each case, by considering the different degrees of certainty and confidence each…

Presents a case study of an experienced high school chemistry teacher. Examines the teacher's conceptions about teaching science and compares them with the observed patterns of practice. Highlights the complexity of characterizing a teacher's thinking and its relationship to actions. Discusses the value of the insight researchers gain from sharing…

Explores a way to analyze and describe learning derived from both constructivist theoretical considerations and classroom practice. Presents a model describing possible student responses during science lessons. Provides a rationale on the basis of both constructivist theory and tests of the model in middle school science classes. Contains 42…

Supports the assertion that constructivism is a sound theory that explains the practice of science and science pedagogy, and responds to critics of constructivism. Offers a constructivist account of some long-standing epistemological issues. Contains 40 references. (DDR)

Highlights the old but important debate about the difference between statistical significance and the practical or educational value of research findings. Argues for proper reporting of quantitative research using meta-analysis methods developed in the 1970s. Contains 53 references. (DDR)

Explores the relationship between subject matter and secondary science teacher identity, or sense of self. Develops a multidimensional model of identity and discusses the role of subject matter in the teachers' descriptions of who they are. Contains 30 references. (DDR)

Addresses the question of what bearing the nature of educational theories has on their application to practice and focuses on the application of normative goal-directed theories of science education. Contains 40 references. (DDR)

In response to an article in the same issue by Norris and Kvernbekk, argues that the theory of Driver and associates, elaborated upon in the three articles which form the basis for their analysis, is not a normative goal-directed theory. (DDR)

Reports on a study designed to identify the hierarchical relationships among Piagetian cognitive modes and integrated science process skills for different Piagetian cognitive reasoning levels, and to determine whether positive vertical transfers could be validated. (TW)

Argues that the knowledge explosion in science promotes a perception that scientific knowledge is temporary and unreliable. Presents an ecological example that partially supports these conclusions. Contains 35 references. (DDR)
