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…

While recent research has examined students' and teachers' understanding of models and modeling, few studies have focused on how teacher educators can support preservice elementary science teachers in envisioning enriched learning processes and outcomes for their students while engaging in modeling practices. Informed by reflective practices…

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…

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…

In this study we investigated how a theoretical framework we developed for making differentiated instruction practical worked out in a trajectory (1 year, 5 sessions) that aimed to support 5 secondary biology teachers in designing differentiated instruction practices. The key feature of the framework is the development of cost-effective…

In this study, we present a conceptual tool for guiding teachers' principled pedagogical actions toward equitable instruction, referred to as the "Transforming Science Learning" (TSL) framework. The TSL framework was developed to address the challenges of enacting an ideological commitment in local contexts--promoting equity and justice…

Prospective teachers perceive peer coaching as a supportive learning opportunity providing benefits in peers' engagement in active learning, communicative competences, and critical thinking about teaching. Little is known about whether peer coaching also promotes the development of pedagogical content knowledge (PCK) in teacher education, which is…

The Next Generation Science Standards call for changes in not only what is taught in elementary science but also how students engage in the learning experience to develop understanding of core disciplinary ideas. In this study we examined 5th-grade teachers' pedagogical content knowledge (PCK) for 1 particular core idea: the small particle model…

Specialized science courses (SSCs) integrate content knowledge (CK) with pedagogical content knowledge (PCK) and prepare pre-service teachers (PSTs) for reform-oriented teaching. Studies of individual SSCs report positive short-term outcomes, including an increase in self-efficacy and CK. However, few studies explore the longer-term impact of SSCs…

Science, technology, engineering, and math (STEM) education has become an international focus of science education curricular reforms. However, few K-12 teachers have the background to authentically teach STEM in an integrated way. This is especially true of elementary teachers, who are often less confident or prepared to teach STEM disciplines…

We report on one teachers' efforts to re-design an entire instructional unit as a coherent storyline about forces and motion as a part of a multiyear professional development (PD) project around the NGSS. Designing coherent storylines demands that teachers create opportunities for students to meaningfully engage in science practices in order to…

This study explores Ethiopian preservice primary science teachers' perception of mentoring practices. Using a survey design, the Amharic translation of Mentoring for Effective Primary Science Teaching (MEPST) was administered to 239 graduating preservice science teachers, enrolled in four teacher education colleges. In addition, we interviewed 20…
