Teacher professional development (PD) is essential to continuously improve teaching skills, to adapt to diverse student needs, and to promote equity and inclusion. Only a few studies to date have synthesized how PD programs improve teachers' content knowledge and instructional quality, as well as students' academic performance. In this…

Exploring how science teacher education programs can prepare science teachers to support gender and sexually diverse students remains an important area for research. A 5-week intervention was designed for pre-service science teachers' (PSSTs), addressing gender and sexual diversity (GSD). The effects of the intervention on PSSTs' attitudes and…

This study used a cluster randomized controlled trial to investigate the effectiveness of two approaches to increasing middle school students' science learning when using an inquiry-based science curriculum. Eighty-nine schools, with 253 teachers and 20,591 students, were randomly assigned into one of three conditions: (a) a treatment condition in…

Knowledge of science content and the ability to translate knowledge into effective teaching is known as teachers' "content knowledge for teaching" (CKT). Teachers with developed CKT are able to more effectively determine instructional and assessment activities that will deepen K-12 students' scientific literacy. However, preservice…

Grappling with uncertainty is an essential element of students' science learning and sense-making processes, yet literature is limited regarding how teachers can facilitate and use student scientific uncertainty as a pedagogical resource in their classrooms. Furthermore, progress on pedagogical practice depends on both the ability to notice one's…

As professional science becomes increasingly computational, researchers and educators are advocating for the integration of computational thinking (CT) into science education. Researchers and policymakers have argued that CT learning opportunities should begin in elementary school and span across the K-12 grades. While researchers and policymakers…

The Framework for K-12 Science Education set an ambitious goal of broadening participation in science learning for all students. Meeting this vision will involve supporting teachers in making meaningful connections with the cultural and linguistic resources their students bring to school; in essence, developing pedagogies that frame these…

Explicitly attending to justice in science teaching and learning is long overdue. Here, we examined the professional teacher identity development of 13 science teachers as they collaborated in networked professional learning communities (PLCs) to implement and revise a culture-setting unit focused on the science of COVID and engaging in…

Advances in online geospatial technologies (GST) have expanded access to K-12 classrooms which has implications for the support teachers require to effectively integrate GSTs to promote learning. Previous studies have shown the impact of GST-integrated lessons on student engagement, spatial thinking skills, and/or content knowledge; however, most…

In teacher professional development (PD), grouping teachers with varying levels of experience can be a productive and empowering way to stimulate the exchange and co-generation of content and pedagogical knowledge. However, less experienced teachers can face socio-emotional risks when engaging in collaborative science content reasoning tasks with…

There is strong agreement in science teacher education of the importance of teachers' content knowledge for teaching (CKT), which includes their subject matter knowledge and their pedagogical content knowledge. However, there are limited instruments that can be easily administered and scored on a large scale to assess and study elementary science…
