“…In disciplinary learning, researchers have identified different types of uncertainty based on the goals of their research (e.g., Chen, 2021;Gouvea & Wagh, 2018;Hartner-Tiefenthaler et al, 2018;Jordan & McDaniel Jr, 2014;Zaslavsky, 2005). Because this study focuses on how students develop knowledge through modeling and considers modeling as an epistemic practice (Campbell & Oh, 2015;Ke & Schwarz, 2021;Windschitl et al, 2008), I focus on epistemic uncertainty within the framework of modeling. Epistemic uncertainty in modeling can be defined as students' decisions, wonder, conflict, perplexity, doubt, and struggle about how to explain a phenomenon, how to build a model to represent a phenomenon, how to use models to construct claim and evidence from raw data, and how to use a scientific argument to build a theory acceptable to a classroom community.…”
