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…

New reforms and the Next Generation Science Standards call for three-dimensional learning through the integration of the crosscutting concepts (CCCs) with the science and engineering practices (SEPs) and disciplinary core ideas (DCIs). However, teachers face challenges in knowing how and why to incorporate the CCCs in their planning and teaching,…

Integrated science-and-literacy programs have proven to positively affect both language proficiency and science knowledge. Because making connections is important in both text comprehension and understanding the disciplinary core ideas taught in science, it seems worthwhile to explore the potential of integrating text structure instruction in…

Designing and analyzing lesson plans is a ubiquitous practice in teacher education, and yet we know little about how preservice teachers (PSTs) notice elements of their lesson plans that afford opportunities for supporting equitable student sensemaking. We investigate how the use of a tool, a framework for supporting equitable sensemaking, guided…

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…

In an effort to deepen learning in K-12 science classrooms, there has been a national movement to integrate computational thinking (CT). The purpose of this phenomenographic study was to understand teachers' perceptions of the function and usefulness of a task analysis and a decision tree tool designed to help them with integration. Teachers…

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…

Literature suggests the transfer of understanding the nature of science to instructional practice requires preservice teachers to value teaching about the nature of science. Despite decades of research developing preservice teachers' views of nature of science, there is still a disconnect between their understanding and instructional practice.…

Research has explored how science teachers can create equitable learning environments. In addition, research demonstrates that representations can be powerful tools for supporting disciplinary learning and inviting and leveraging students' diverse ideas and practices. Yet, professional development (PD) about representations has primarily focused…

Preservice elementary teachers need to be able to engage young students in science practices but may not have extensive experiences with those practices. They also may have contrasting beliefs about them, which inform their teaching practice. To understand preservice teachers' beliefs related to science practices, we focus on the connections they…

Understanding Nature of Science (NOS) is a requisite for improving scientific literacy, and as such, it is increasingly being included in science curricula worldwide. It is now therefore important that teachers understand NOS so that intended learning outcomes become visible in the classroom. Pre-service teachers also need an opportunity to…

This study investigated the nature of the pedagogical content knowledge (PCK) development among 22 prospective teachers enrolled in an elementary science methods course. The nature of prospective teachers' PCK development was investigated in relation to their experiences in planning, enacting, and reflecting upon a Physical science lesson. The…

We present an empirically based model for teaching about planning in pre-service science teacher education as part of on-campus courses. Planning is usually taught through the introduction of theoretically based planning models, but these models commonly assume a linear idea of planning that does not match how teachers go about planning. We…

Although teachers' instruction has been extensively studied, there is a dearth of research investigating how teachers design lessons and integrate new information into their existing lessons. This study utilized a case study approach to examine how teachers engaged in a nanoscale science professional development experience integrated new science…

Although microteaching is a common approach to engaging preservice teachers in reflection on teaching in on-campus courses, this reflection is usually carried out as a separate part. We examined how preservice middle school science teachers reflected amid planning a 20-min microteaching unit on sustainable development. Six groups of preservice…
