There is a general consensus that design-based research (DBR) is a genre of approaches in education research to design interventions for specific problems with the aim to gain an understanding of how they work in the problem context. While there is a considerable body of literature discussing the epistemic and methodological aspects of DBR, we…

In this article, we critically examine what a commitment to equity, diversity, and social justice in science and science education means for our research practices and methods. Using a blend of critical cross-cultural and feminist lenses, we explore relationships of power in our research, specifically in terms of knowledge production,…

Research on science teacher cognition is important as findings from this research can be used to improve teacher training, leading to improved classroom practice. Previous research has often relied on two underlying assumptions: Cognition is an individual process, and these processes are detailed and introspective. In this paper, we put forth a…

The national efforts underway to include engineering in K-12 science education present a variety of new challenges, including how to prepare teachers to teach a new discipline. In this paper, we focus on elementary teachers and how they enter into "responsive teaching," in which they closely attend and meaningfully respond to students'…

This review examines 105 empirical studies that investigate students' views of the nature of science (VNOS), effects of curricular interventions on changing students' VNOS, and relations between VNOS and demographics, majors, and learning of science. The reviewed studies can be categorized into three theoretical frameworks: the unidimension, the…

The role of visualization and model-based reasoning has become increasingly significant in science education across a range of contexts. It is generally recognized that supporting learning in developing causal explanations for observed astronomical events presents considerable pedagogic challenge. Understanding the Sun's apparent movement…

In this article, we use a narrative methodology to understand the work of three teachers who have constituted identities that have allowed them to challenge the contemporary discourse of science education. We describe how teachers' evolving identities have been constituted through their responses to the discourses and situations of their work and…

This article examines the use and role of the term "experiment" in science teacher education as described by teacher students. Data were collected through focus group interviews conducted at seven occasions with 32 students from six well-known Swedish universities. The theoretical framework is a sociocultural and pragmatist perspective…

Much of the research on students' understanding of the greenhouse effect and global warming reports poor results. Students are claimed to hold misconceptions and naive beliefs, and the impact of teaching on their conceptions is also low. In the present study, these results are called into question, and it is argued that they may to a large extent…

Research hypotheses versus statistical hypotheses, null hypotheses and alternative hypotheses, and statistical significance versus practical significance are described and illustrated. (CP)

The last decade has brought considerable progress in our understanding of how institutions like museums affect people's lives. However, there is still a great deal we do not know, and the research challenges ahead sometimes appear quite daunting. In this paper, we suggest that three characteristics of learning, its personal nature, that it is…

Discusses reliability, validity, and rigor in qualitative educational research and the need for replacing validity and reliability with a concept that values human affairs as the purpose of research. (Contains 28 references.) (YDS)

Indicates that the explanation of what it means to obtain a significant F-ratio in discriminant function analysis, presented by K. E. Anderson in an earlier volume of Science Education, is incorrect. (JR)

Describes the difficulties encountered in selecting material to be included in the reviews of science education research in the Curtis Series'' published by the Columbia Teachers' College Press. Presents evidence outlining the weaknesses of using a jury'' to determine so-called superior research. (AL)

Describes the methods employed in identifying the problems connected with science teaching of greatest concern to a group of 50 science teachers attending a workshop at the University of Wyoming. Results of the survey and treatment of the data are reported. (JR)
