Despite the growing field of research focusing on the benefits of learning science in the outdoors where students have direct connections with the natural world, teachers report that challenges such as time and test preparation discourage outdoor science instruction. Additionally, many teachers feel ill-equipped and a lack of support from…

This study employed a sequential mixed methods explanatory research design to explore the influence of mentoring in the self-efficacy-forming experiences of primary school teachers who participated in a variety of professional development projects on science teaching. In the quantitative phase, survey data drawn from primary school teachers…

Researchers of science education, historians, and philosophers of science agree that the teaching of nature of science (NOS) is important to be integrated into K-12 classes. Our previous research showed that NOS is not embedded into science teaching in Greece. To study the possibility of its integration, a PD-program for in-service science…

The "A Nation at Risk" report was released in 1983 and enumerated systemic flaws in the U.S. education system, highlighting science education as an area of concern (Denning, 1983). Over a generation later, a new opportunity has emerged to improve science education for all students, and especially the youngest learners. The Next…

The purpose of this study was to conceptualize a pedagogical content knowledge framework for informal science educators (ISE-PCK). An initial, hypothetical framework was created grounded in the literature in informal science education (ISE) as analogous to PCK models in formal science education. An exploratory sequential mixed-methods research…

This dissertation focused on the outcome of elementary science teachers' learning in theories and practices of epistemic tools in professional workshops over the course of two years, starting in the summer of 2019. Study one focuses on teachers' understanding of language as an epistemic tool. The data were teachers' written responses to a…

Exploring how science teacher education programs can prepare science teachers to support gender and sexually diverse students remains an important area for research. A 5-week intervention was designed for pre-service science teachers' (PSSTs), addressing gender and sexual diversity (GSD). The effects of the intervention on PSSTs' attitudes and…

This article reports on the effect of textbook analysis as a tool of teacher professional development on nature of science (NOS) understanding of 10 science teachers in South Africa. The teacher professional development program (TPDP) was based on an explicit reflective methodology of textbook analysis and conducted online due to the Covid-induced…

Grappling with uncertainty is an essential element of students' science learning and sense-making processes, yet literature is limited regarding how teachers can facilitate and use student scientific uncertainty as a pedagogical resource in their classrooms. Furthermore, progress on pedagogical practice depends on both the ability to notice one's…

Instructional shifts required by equitable, reform-based science instruction are challenging, especially in the elementary context. Such shifts require professional development (PD) that supports teacher internalization of new pedagogical strategies as well as changes in beliefs about how students learn. Because of this complexity, many PD…

This study explored K-12 teachers' understanding and implementation of the Next Generation Science Standards (NGSS) during and after participation in a professional development (PD) program that included the development of science teachers' conceptual understanding of science. We add to the literature with our focus on a multi-year PD program…

The purpose of this case study was to investigate the perception and experience of ten new faculty member participants in paired teaching. Along with providing evidence for paired teaching as an avenue for professional development in higher education, the study provides experiential narratives of paired teaching relationships as an illustration of…

Teachers' self-efficacy influences their ability to teach students. Primary grade teachers (K-3) are tasked with teaching all content areas. K-3 teachers struggle with self-efficacy to teach science content rigorously and find the time to teach science through hands-on learning. This study addressed the gap in research for teaching science through…

Reforms such as the Next Generation Science Standards (NGSS) call for substantial change in teacher practice such as instruction that is more phenomenon-based, three-dimensional, supportive of student epistemic agency, and coherent from the student perspective. Such change requires ongoing support in the form of aligned curricular materials and…

During a 10-week professional physical science professional development (PD) course, elementary inservice teachers (n = 18) in a large urban district were engaged in explicit-reflective nature of science (NOS) instruction. Teachers were also explicitly engaged in reflection concerning NOS pedagogy (e.g., explicit-reflective, role of context).…
