Out-of-field teaching is a global educational challenge. In particular, many teachers whose academic background and main teaching experience is in biology are called to teach middle school physics and have limited opportunities for productive professional development. Based on previous studies, we expect these teachers to hold different epistemic…

As a hallmark of authentic science practices, students need to enact epistemic agency to shape/reshape the key aspects of their inquiry work as a collaborative community. This study elaborates an emergent temporal mechanism for engaging students' epistemic agency: "reflective structuration" by which members of a classroom community…

Few studies have examined how professional learning communities (PLCs) engage in collaborative inquiry over multiple years. This longitudinal study explored how a team of high school science teachers collaborated with researchers and district-based coaches in a PLC over 4 years. We examined (1) how the PLC, which was situated in a culturally and…

Uncertainty is endemic to scientific research practices; therefore, it is also an important element in learning about science. Studies have shown that experiences and management of uncertainty regarding the epistemic practices of science can support learning. Whereas the common strategies of supporting students in handling uncertainty rely on the…

Epistemic understanding of science is essential for critical evaluation of scientific claims. In principle, developing students' epistemic understanding would enhance students' capability in evaluating scientific claims. However, findings on this "expected" connection have been inconclusive. This paper seeks to examine this discrepancy…

Many classroom units and lessons are now organized around engaging students in developing claims and evidence. An aspect of teachers' work that is understudied is how teachers manage the complexity inherent in navigating between claims and empirical data. In other words, what do teachers do when students do not see what they are "supposed…

This study explores how elementary teachers and students use hedges (tentative words such as "maybe") and boosters (expressions of certainty such as "clearly" and "obviously") during science inquiry discussions. Drawing upon semiotic theory, we examine explicit thematic patterns (semantic meaning relations among science concepts) as well as hidden…

Responds to Jim Garrison regarding his views on school science epistemology. Argues that the goal of science education is to "convey some understanding of scientific practice as it occurs in the everyday world in which we live." (Author/YDS)

Describes current debates over the nature of science in the science curriculum. Illustrates the subtle ways in which epistemological portrayals have been influenced with regard to the public's relationship with institutional science in the United States by using the curricular ideas of John Dewey and Joseph Schwab as an historical perspective.…

Focuses on two of the principal issues for science curriculum developers who wish to introduce the history and philosophy of science into science teaching along with the justification for and the placement of historical materials within teachers' work schemes. Proposes a new model for inclusion of such material that directly addresses children's…

Argues that the National Science Education Standards is an atheoretical document because it fails to prescribe scientific theories worth knowing, define the role of scientific theories in scientific literacy, or outline a framework to conduct research on the inquiry method. (DDR)

Presents a theoretical framework for evaluating inquiry tasks and how similar they are to authentic science. Suggests that inquiry tasks commonly used in schools evoke reasoning processes that are qualitatively different from the processes employed in real scientific inquiry, and school reasoning tasks appear to be based on epistemology that…

It has long been a goal of science education in the United States that students leave school with a robust understanding of the nature of science. Decades of research show that this does not happen. Inquiry-based instruction is advocated as a means for developing such understanding, although there is scant direct evidence that it does. There is a…
