Issues regarding scientific explanation have been of interest to philosophers from Pre-Socratic times. The notion of scientific explanation is of interest not only to philosophers, but also to science educators as is clearly evident in the emphasis given to K-12 students' construction of explanations in current national science education reform…

As a practical theory of language, translanguaging refers not only to speakers' use of multiple languages, but also to the deployment of other semiotic resources and artifacts in communication. To examine the use of semiotic resources and translingual negotiation strategies in STEM communication, this study explores the intersectionality of…

Drawing on racial battle fatigue as theoretical framing and critical race methodology, we offer the counterstories of 16 Black men doctoral scientists and engineers who relied on same race peer support to successfully persist in their science and engineering (S&E) doctoral programs. Our analysis of narratives and interviews yielded three…

Our short-term longitudinal study explored undergraduate students' experiences with performing authentic science practices in the classroom in relation to their science achievement and course grades. In addition, classroom experiences (felt recognition as a scientist and perceived classroom climate) and changes over a 10-week academic term in STEM…

In this study, Social Cognitive Career Theory (SCCT) is used to explore changes in the career intentions of students in an undergraduate research experience (URE) program at a large public minority-serving college. Our URE model addresses the challenges of establishing an undergraduate research program within an urban, commuter, underfunded,…

Recent decades have seen an increasing emphasis on linking the content and aims of science teaching to what the average citizen requires in order to participate effectively in contemporary society, one that is heavily dependent on science and technology. However, despite attempts to define what a scientific education for citizenship should ideally…

Prior research shows that undergraduates tend to identify more strongly with the field of science after participating in scientific research. However, mediators that might account for this association are not well understood. In the current study, we propose that science self-efficacy may serve this mediational function. Specifically, data from a…

In this study, we conducted in-depth interviews with 52 college graduates as they entered a Postbaccalaureate Research Education Program (PREP). Our goal was to investigate what it means for these aspiring scientists, most of whom are from groups underrepresented in the sciences, to feel ready to apply to a doctoral program in the biomedical…

The body of research aimed at explaining the science teaching and learning of African Americans has identified myriad factors that correlate with African American's science career choices and science performance generally. It has not, however, offered any satisfactory explanations as to why those factors are disproportionately racially determined.…

This study explores how students' physics identities are shaped by their experiences in high school physics classes and by their career outcome expectations. The theoretical framework focuses on physics identity and includes the dimensions of student performance, competence, recognition by others, and interest. Drawing data from the Persistence…

The study of the identity processes of women of color in science-based fields helps us (a) find ways to support similar women, and (b) study the dynamics of inequity, within and beyond science. Participants in this study (a Black woman, a Latina, and an American Indian woman) survived inadequate high schools and discouraging college science…

This study investigated the representations of a select group of scientists (n = 10) in a sample of Canadian high school and college textbooks. Drawing on semiotic and cultural-historical activity theoretical frameworks, we conducted two analyses. A coarse-grained, quantitative analysis of the prevalence and structure of these representations…

This study tracked the influence of explicit reflective instructional methods on cultural values, ethical and intellectual development, and the relationship of these with preservice teachers' views of nature of science (NOS). The researchers used the Views of Nature of Science Form B (VNOS B) to describe NOS views, the Learning Context…

At the start of their first semester, 35 college freshmen were given an interview probing (a) their differentiation of scientists' ideas from evidence, and hypotheses from theories; (b) their understanding of the inherent uncertainty of scientific knowledge; and (c) their reasoning about scientific controversies. The most common responses were in…

In this study, we develop a model of science identity to make sense of the science experiences of 15 successful women of color over the course of their undergraduate and graduate studies in science and into science-related careers. In our view, science identity accounts both for how women make meaning of science experiences and how society…
