Teaching practice internships provide opportunities for pre-service teachers (PSTs) to enact their knowledge in real classroom settings. This paper investigated PSTs' pedagogical content knowledge (PCK) about electrostatics, its translation into practice and factors that affect the translation. The refined consensus model (RCM) of PCK served as…

The use of data to explain natural phenomena has been a core feature of science education, and science educators continue to call for an increased emphasis on teaching data practices. This mixed methods design-based research study adds to the growing body of research on data practices in science by explaining the learning trends of science…

This study examined the impact of a practice-based approach to in-service science teacher education, using small-group discussions about photovoltaic (PV) science to support teachers' instruction on sustainable energy transitions in response to climate change risks. Ultimately, we aimed to promote teachers' PV science comprehension as well as…

Teachers' career choice motives are defined as the interests, orientations, and motives of young people that motivate them to aspire the teaching career. Teachers' career choice motives have been shown to impact teaching and job retention. Many studies investigated teachers generic career choice motives but studies on teachers' subject-specific…

Practical, or laboratory, work is a common pedagogical strategy used in school science classrooms, yet its effectiveness for enhancing student learning is contested. Developing teachers' pedagogical knowledge about planning for practical work can improve its effectiveness by ensuring that tasks are well-conceived and effective for linking what…

Traditional teacher professional development (PD) programs frequently lack sufficient face-to-face preparation time to adequately support the implementation of evidence-based pedagogical strategies in classrooms, with teachers citing insufficient preparedness and training time for new methods. To investigate potentials for online PD methods to…

Science Olympiad is a K-12 science, technology, engineering, and mathematics (STEM) competition that engages approximately 7,000 teams across the U.S. in individual and team challenges at regional, state, and national levels. Science Olympiad began expanding to include elementary students in 2008. Yet, little is known about the adults who…

The teaching of genetics has not been effective in promoting a scientifically acceptable understanding of basic genetics concepts. This study addresses that gap by reporting on topic-specific pedagogical content knowledge (PCK) enacted by a teacher educator as she teaches a content course on basic genetics concepts to fourth-year pre-service…

This study explored whether, and how, preservice elementary teachers' scientific curiosity related to their confidence for science teaching. A group of 29 preservice, elementary teachers in the U.S. engaged in a curiosity journaling strategy across a 16-week scientific inquiry course. Their expressions of curiosity were coded using Luce and Hsi's…

This work reports a classroom experience of a general physics course designed to foster also the initiation of preservice mathematics and biology teachers to physics pedagogical content knowledge. To modify the conceptions that these students have about teaching and learning, the course was taught using different active learning instructional…

National reform documents and shifts in educational standards have continued to highlight the importance of engineering and engineering practices within science literacy. High-quality engineering opportunities must be present in formal education due to their association with problem-solving and critical thinking. Given this directive to reach…

Science teachers should be able to notice student preconceptions in order to adapt instructions to their students' needs and support the learning process. Noticing as a core practice of teaching should thus be implemented early in science teacher education. A crucial prerequisite for noticing is knowledge about students' preconceptions, which is…

Effective professional development programs (PDPs) rely on well-defined goals. However, recent studies on PDPs have not explored the goals from a multi-stakeholder perspective. This study identifies the most important learning goals of PDPs at science research institutions as perceived by four groups of stakeholders, namely teachers, education…

This study adds to the construct of science teacher noticing through an analysis that integrates concepts from pedagogical content knowledge (PCK) frameworks. It examines 929 instances of science teacher noticing made via video annotation tools (VATs) over the course of 38 early-career, secondary science teachers' participation in a two-year…

Evolution is a difficult topic to teach; teachers admit not having enough knowledge of evolution and they face student opposition to learning evolution, especially based on religious grounds. Teachers are therefore motivated to gain knowledge in the field of evolution. We conducted a 30-hour evolution teacher training course, which included…
