Science

This study explored the potential impact of teaching outside of one’s field of expertise. This longitudinal cross-case study examined the development of enacted pedagogical content knowledge (ePCK) among a group of in-field and out-of-field (OOF) physical science teachers during their first 3 years of teaching. The components of ePCK investigated included the knowledge and skills related to conceptual teaching strategies and student understanding of science. Seventeen newly hired teachers teaching in and outside their field of expertise participated in the study.

Argumentation enables students to engage in real world scientific practices by rationalizing claims grounded in supporting evidence. Student engagement in scientific argumentation activates the negotiation process by which students develop and defend evidence-based claims. Little is known, however, on the intricate process and potential patterns of negotiation between students during scientific argumentation.

We present lessons learned from an ongoing attempt to conceptualize, develop, and refine a way for teachers to gather formative assessment evidence about classroom argumentation as it happens. The system—named DiALoG (Diagnosing Argumentation Levels of Groups)—includes a digital scoring tool that allows teachers to assess oral classroom argumentation across two primary dimensions: one to capture the Intrapersonal, discipline-specific features of scientific arguments, and another to capture the Interpersonal, group regulatory features of argumentation as a dynamic social act.
