The Next Generation Science Standards and increasing linguistic diversity of students in United States science classrooms require language-focused science instruction for which many secondary science teachers are not prepared. To date, minimal research has addressed how to best support secondary science pre-service teachers (PSTs) in teaching in…

Science education policies and standards have called for educators to teach students about the Nature of Science (NOS) and engage them in Culturally Relevant Science Teaching (CRST), which requires critical shifts away from traditional science teaching. As such, teachers are being asked to possess or take up conceptions of science that challenge…

Science teachers' beliefs about teaching and learning are a vital component of teachers' professional competence and are often assumed to impact classroom practice. To date, these beliefs have been predominantly investigated regarding teaching and learning in general or for a particular science subject (e.g., physics). It remains to be determined…

This study evaluated the representations of nature of science (NOS) in U.S. state science standards, and examined the changes in these representations from documents advanced in the 1980s through 2016. Drawing from the consensus perspective on NOS and prior studies focusing on the analysis of textual content, documents were inspected for 10 target…

The ability to design and interpret controlled experiments is an important scientific process skill and a common objective of science standards. Numerous intervention studies have investigated how the control-of-variables-strategy (CVS) can be introduced to students. However, a meta-analysis of 72 intervention studies found that the opportunity to…

This research studied a group of three preservice elementary teachers creating a narrated stop-motion animation (Slowmation) from start to finish in 3?hours to explain the challenging concept of "phases of the moon" to elementary school children. The research questions investigated the preservice teachers' learning before and after the…

This study explores the experiences of six urban middle school students in an authentic science inquiry program. Drawing on data including teaching journal entries, student work folders, and semi-structured focus group interviews of six participants, the findings explore six dimensions of authentic science inquiry, an approach to science inquiry…

The central goal of this study was to characterize the mental models of acids and acid strength expressed by advanced college chemistry students when engaged in prediction, explanation, and justification tasks that asked them to rank chemical compounds based on their relative acid strength. For that purpose we completed a qualitative research…

When evaluating equity, researchers often look at the "achievement gap." Privileging knowledge and skills as primary outcomes of science education misses other, more subtle, but critical, outcomes indexing inequitable science education. In this comparative ethnography, we examined what it meant to "be scientific" in two fourth-grade classes taught…

This study assessed the representations of nature of science (NOS) in high school chemistry textbooks and the extent to which these representations have changed during the past four decades. Analyses focused on the empirical, tentative, inferential, creative, theory-driven, and social NOS, in addition to the myth of "The Scientific Method," the…

This study investigates the interaction between four pairs of high school students in a 7-week national research apprenticeship program. Each student was interviewed about perceptions of experiences working with a peer in the same setting, and the resulting stories were analyzed. Through discourse analysis of the interviews and interrelated…

Under current conditions evaluative research based on curriculum products of master teachers using basic knowledge from the social and natural sciences is more likely to contribute to the improvement of educational practice than is an attempt to build theories of teaching based upon rapidly changing philosophy and technique.

Presents a rebuttal to Roth's criticisms (SE 550 636) of author's 1990 article. Asserts all disciplined inquiry is reductionistic in the sense that reportage cannot reproduce experience in toto, nor should it be seen to do so. Argues that experimentation is fundamental method of science and that scientific approach to science education cannot do…

Criticizes the methods and assumptions of a study that attempted to determine a standard list of tenets for the Nature of Science via statistical sampling of members of the Philosophy of Science Association (PSA). Provides a taxonomy of philosophic issues and suggests some roles for philosophy of science in science teaching and science-teacher…

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…
