Although visual aids are widely considered a valuable source of scaffolding, the nature and active utilization of these aids in current science classrooms are not well understood. This qualitative study explores interaction in the teaching of concepts related to evolution, with a specific focus on a teacher's use of different visual support…

Despite the importance of developing elementary science teachers' content knowledge for teaching (CKT), there are limited assessments that have been designed to measure the full breadth of their CKT at scale. Our overall research project addressed this gap by developing an online assessment to measure elementary preservice teachers' CKT about…

This comparative case study explored the ways two elementary Teachers of Color's science teacher identities and agency to teach science developed as they participated in a year-long science professional development that was situated within the high-stakes testing context of their school. The science professional development model used a dialogical…

The Framework for K-12 Science Education details new goals to guide improvement of US science education. Among the new goals, the inclusion of engineering core ideas and practices stand out. We report a case study of four 8th-grade science teachers who chose to integrate engineering core ideas and practices into their science classes by teaching…

Inquiry learning pedagogies have not only been proposed as a successful teaching methodology to draw students into science, they are also rich with possibilities for creativity. The particular focus on investigations and problem-solving provides opportunity for educators to embrace this. The primary curriculum explicitly values creativity in this…

Although the use of active learning pedagogies in college science courses has been demonstrated to improve student learning and engagement, lecture-based methods still feature predominantly across university courses. Often lacking meaningful opportunities to learn about and test out new pedagogies, faculty have been slow to adopt and enact new…

Teachers' use of formative assessment (FA) has been shown to improve student outcomes; however, teachers enact FA in many ways. We examined classroom videos of nine experienced teachers of elementary, middle, and high school science, aiming to create a model of FA enactment that is useful to teachers. We developed a coding scheme through a…

Through a randomized controlled trial, this mixed-methods study evaluated changes in elementary science teachers' understandings, confidence, and classroom implementation of problem-based learning (PBL), inquiry, and nature of science (NOS) instruction following participation in a professional development (PD) as well as the components of the PD…

The purpose of this study is to challenge the prevailing negative narrative related to elementary science teaching by investigating the experiences of elementary teachers who identify as science teacher enthusiasts (STEs). Holland, Lachiotte, Skinner, and Cain (1998)'s conception of identity as an ongoing production or construction in a…

In an effort to document teachers' enactments of new reform in science teaching, valid and scalable measures of science teaching using engineering design are needed. This study describes the development and testing of an approach for documenting and characterizing elementary science teachers' multiday enactments of engineering design-based science…

When collecting data, science education researchers frequently have multiple respondents evaluate multiple artifacts using multiple criteria. Herein, the authors introduce Multifaceted Rasch Measurement (MFRM) analysis and explain why MFRM must be used when "judges'" data are collected. The authors use data from elementary science…

Opportunities for the development of science-related pedagogy during training are necessarily limited for the generalist primary (elementary), preservice teacher. While school placement is an important context within which to develop such professional expertise, the role of institution-based learning is less well understood in this regard. This…

Teachers often engage in curricular planning by critiquing and adapting existing curriculum materials to contextualize lessons and compensate for their deficiencies. Designing instruction for students is shaped by teachers' ability to apply a variety of personal resources, including their pedagogical content knowledge (PCK). This study…

Formative assessment, assessment used to inform subsequent learning, can have a powerful positive impact on student achievement, but little empirical work has been conducted to investigate the role of teachers' knowledge in its practice. This study investigated reciprocal relations between elementary science teachers' formative assessment…

Despite a recent focus on engaging students in epistemic practices, there is relatively little research on how learning environments can support the simultaneous, coordinated development of both practice and the knowledge that emerges from and supports scientific activity. This study reports on the co-construction of modeling practice and…
