A critical component to disciplinary engagement in science is that of epistemic affect--learning how to "feel" as scientists do when engaged in their work. The emotional responses, feelings, and dispositions that emerge as one participates in the construction of knowledge are part and parcel to the experiences of scientists and, we…

Orchestrating opportunities for students to engage in scientific talk in the classroom is challenging for most teachers and even more so for novice teaching assistants (TAs) who typically instruct introductory science laboratories at the postsecondary level. This study was designed to understand how TA moves are related to instances of scientific…

In this quantitative study, we compare the efficacy of Level 2, guided inquiry-based instruction to more traditional, verification laboratory instruction in supporting student performance on a standardized measure of knowledge of content, procedure, and nature of science. Our sample included 1,700 students placed in the classrooms of 12 middle…

The first years of teaching can be demanding, as the novice works to gain familiarity with many aspects of professional work. Often, what they have been prepared to do in teacher education programs is not aligned with what is expected at them in schools. As a consequence, many teachers leave the profession or move away from the reform-minded…

Inquiry is seen as central to the reform of science teaching and learning, but few teachers have experience with scientific inquiry and thus possess very naive conceptions of it. One promising form of professional development, research experiences for teachers (RETs), allows teachers to experience scientific inquiry in the hopes that these…

The focus of this research was to understand how a program for women in science, mathematics, and engineering (SM&E) at college level in the southeastern United States functioned to influence women's decision making in terms of participation in these fields. By employing Lave and Wenger's theory of situated learning, we explored this program…

This research focused on the interactionist conceptual ecologies of inservice teachers and how these ecologies influenced these teachers' conceptual frameworks for the nature of science (NOS). The participants in the study were five teachers enrolled in a graduate course focused on NOS. Data included participants' responses to open-ended and…

Interpretive analysis of preservice teachers' writings and discussions during an elementary-science methods course identified the teachers' positivist views of knowledge, learning, and teaching as prominent tools for guiding understanding of and reaction to ideas of teaching science to diverse student populations. Discusses the impact on teachers'…

Explores two differing perspectives of the nature of students' biological knowledge structures, conceptual frameworks, and phenomenological primitives (p-prims). Indicates that although a more prevalent description of student conceptions could not be discounted, p-prim of need as rationale for change was found to offer useful description of…
