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…

Learning to plan modeling-based investigations (MBIs) presents significant challenges for pre-service elementary teachers. Although they understand disciplinary core ideas and modeling practices, they address both as competing learning goals and, as novices, they have not experienced how to structure MBIs for their future students. In the context…

Developing knowledge about science instruction is critical for preservice teachers. This study explores how 79 elementary preservice teachers perceive the relevance and importance of assessment task scenarios designed to elicit information about content knowledge for teaching (CKT) about matter and its interactions--a foundational topic for…

Recent national reforms focus on learning disciplinary core ideas through engaging in science and engineering practices. These reforms also call for students and teachers to use crosscutting concepts (CCCs), or analytical lenses, that support scientific sensemaking and connections across disciplines. The "Framework for K-12 Science…

As elementary schools across the U.S. continue to adopt new science education reform, attention is needed to understand how teachers make sense of using engineering design to teach science in their classroom settings. This study examined fourth-grade teachers' sense-making with learning to integrate engineering design-based science instruction and…

To support science teachers in learning how to engage in ambitious teaching practices, teacher educators, professional development facilitators, and researchers need to develop a nuanced understanding of the pedagogical content knowledge (PCK) that science teachers access and use in their daily work. Despite the consensus on the importance of…

We report on seven secondary science teachers' initial efforts to understand and enact NGSS-aligned teaching. After interviewing and observing them over the course of the school year, we found that teachers revised their lessons to include instructional strategies that aimed to meet the demands of the NGSS. Yet at times, the purpose for which…

The academic language of science includes science content words and words that describe the practices of scientists. The present study examined science vocabulary knowledge and science vocabulary instruction practices of pre-service teachers enrolled in a primary science methods course. This exploratory mixed-methods study presents quantitative…

To bridge the gap for English language learners (ELLs) in science, hybrid language affords the opportunity for students to communicate through various modes, including natural language, visual representations, mathematical expressions, and manual-technical operations. The purpose of this study was to investigate how ELLs use hybrid language (a) to…

Young children need opportunities to engage in the practice of constructing scientific explanations in order to develop their own understanding of science content. To engage in this scientific practice, teachers need to provide young children with explicit instruction and scaffolding. However, many classroom teachers' knowledge and beliefs for how…

Contemporary research has suggested that for students to compete globally, pedagogy must shift to emphasize the infusion of mathematics into science instruction to strengthen understanding. Innovative professional development programs are necessary to achieve this goal, particularly with respect to teaching graphing skills in the context of…

New reforms in science education emphasize facilitating all students' sense making of the big ideas and crosscutting concepts in science along with engagement in science practices. Supporting this learning requires complex, ambitious teaching that is uncommon in U.S. classrooms. Thus, novice teachers will need considerable support in learning how…

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…

In this article, we describe the development process for designing multimedia educative curriculum materials (MECMs) focused on supporting teachers in argumentation. We also describe results from a study with 46 teachers. We were interested in whether teachers' backgrounds or characteristics of the MECMs impacted MECM use. Overall, 89% of the…

In an effort to better prepare science teachers to engage in high-leverage practices, this study investigates the choices and rationales of preservice science teachers in planning elicitation strategies and describes how their understandings about the elicitation of students' ideas changed over time. Four cohorts of preservice science teachers…
