Measure student assistants’ PCK-Q in online settings during COVID pandemic

Abstract

Learning Assistants (LA) are pivotal to non-traditional physics instruction in large classrooms. In this study, we used the framework of Pedagogical Content Knowledge for questioning (PCK-Q) to measure LAs’ questioning skills. We designed a written instrument describing various situations that LAs would encounter while interacting with students. LAs needed to articulate how they would support student learning considering their difficulties. We also developed a coding scheme to analyze how LAs’ questions leveraged students’ conceptual understanding. We administered this written instrument with LAs who had various years of experience in inquiry-based physics courses and analyzed their videos of interacting with students in online settings during the COVID pandemic. We validated the written instrument with class videos, delineated the LAs’ PCK-Q, and suggested how the LAs’ questions contributed to students’ conceptual learning about classical mechanics.
