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…

Engaging preservice teachers in the analysis of videos of teaching has become a widely-used and highly-regarded approach within teacher preparation. This approach has become even more pronounced in the wake of COVID-19.

Practice-based approaches to teacher education should emphasize strategies that help teacher candidates centralize student thinking in instructional practice while providing a rationale for why student thinking is integral to student learning. This study describes how secondary science teacher candidates engage in tool-supported analysis of…

Educational reform needs to address the role of literacy in science if there is to be any hope of achieving the goal of literacy for all U.S. students. For reading to play a more prominent role in secondary science, teacher education programs need to develop and offer courses that familiarize preservice science teachers with disciplinary literacy.…

Though an adequate understanding of content is a natural prerequisite of teaching (Carlsen in "Journal of Research in Science Teaching" 30:471-481, 1993), teachers also need to be able to interpret content in ways that facilitate student learning. How to best support novice teachers in developing and refining their content knowledge for…
