While the opportunity to engage in scientific reasoning has been identified as an important aspect of informal science learning (National Research Council, 2009), most studies have examined this strand of science learning within the context of physics-based science exhibits. Few have examined the presence of such activity in conjunction with live…

This article aims to investigate variations in science achievement for secondary school students across the Trends in International Mathematics and Science Study (TIMSS) assessments and to examine the relations of several student- and school-level factors with achievement. The data were obtained from 5,577, 5,314, and 4,466 Malaysian eighth…

Despite a recent focus on engaging students in epistemic practices, there is relatively little research on how learning environments can support the simultaneous, coordinated development of both practice and the knowledge that emerges from and supports scientific activity. This study reports on the co-construction of modeling practice and…

There is international concern over persistent low rates of participation in postcompulsory science--especially the physical sciences--within which there is a notable underrepresentation of girls/women. This paper draws on data collected from a survey of more than 9,000 10/11-year-old pupils and 170 interviews (with 92 children and 78 parents)…

Social justice education is undertheorized in science education. Given the wide range of goals and purposes proposed within both social justice education and social justice science education scholarship, these fields require reconciliation. In this paper, I suggest a student empowerment framework for conceptualizing teaching and learning social…

This study examined 188 preservice science teachers' professional growth along three dimensions--self-regulated learning (SRL) in a science pedagogical context, pedagogical content knowledge, and self-efficacy in teaching science--comparing four learner-centered, active-learning, peer-collaborative environments for learning to teach higher order…

It has been argued that decision making about socioscientific issue (SSIs) necessitates informal reasoning, which involves multiperspective thinking and moral judgment. This study extends the scope of the literature concerning students' reasoning on SSIs to a cross-contextual study by comparing decisions made on avian flu by 12-13-year-old Chinese…

This study investigated children's judgments of the epistemic status of justifications for causal claims. Twenty-six children (14 boys, 12 girls) between the ages of 8 and 10 were asked to help two story characters choose the "best reason" for believing a claim. The reasons included appeals to an authority, to a plausible causal mechanism, or to…

The goal of this case study was to describe characteristic features of abductive inquiry learning activities in the domain of earth science. Participants were undergraduate junior and senior students who were enrolled in an earth science education course offered for preservice secondary science teachers at a university in Korea. The undergraduate…

This study investigated the modalities of science teaching practice and students' pedagogic subject positioning through the linguistic features of science classroom discourse and the discursive interaction. For this purpose, this study sought to develop a methodology for classroom discourse analysis, the TMARC (Triangular Model of Analyzing…

Our study utilizes data from a national cohort of eighth-grade students to consider how different gender and racial/ethnic subgroups compare to White males in their likelihood to aspire toward a science or math occupation and examine the roles that self-concept, enjoyment, and achievement may play in shaping disparities at this early point in…

Understanding what children know is paramount to planning effective science instruction; however, in any classroom, the students hold a variety of ideas. Representing these differences in ways that also acknowledge the common trends among students might facilitate the process of differentiation. To exemplify one such possible process of…

This study aims to test the nature of the assumption that there are relationships between scientific epistemological views (SEVs) and reasoning processes in socioscientific decision making. A mixed methodology that combines both qualitative and quantitative approaches of data collection and analysis was adopted not only to verify the assumption…

I profile here a prospective method for assessing nature of science (NOS) knowledge, as an alternative to VNOS and similar approaches. Questions about cases in contemporary news and from history probe scientific literacy in context. Scoring targets how "well informed" the analysis is, based on identifying relevant NOS information and interpreting…

As part of a 5-year professional development intervention aimed at improving science and literacy achievement of English language learning (ELL) students in urban elementary schools, this study examined fourth-grade students' science achievement across a 3-year (2005-2008) implementation of our professional development intervention consisting of…
