BK7B: Applying Claims-Evidence-Reasoning to Statistical Argumentation

Abstract

Our team is applying Claims-Evidence-Reasoning framework to data argumentation drawing from previous research (Fielding, 2025). Our aim is to provide tools for guiding teachers through writing and reporting data arguments from the perspective of the Data Investigation Process (Lee et al., 2020). Incorporating Claims-Evidence-Reasoning in the Communicate and Propose Action step enhances the strength of the argument, and helps learners explicate their conclusions in a clear and concise manner. This allows teachers to provide real-world, contextualized scenarios for their students while improving data literacy. We will begin the session by opening up a discussion on what participants think makes a good data argument. We will build this into presenting our findings from a design research study conducted with a professional learning community of secondary mathematics teachers. Finally, we present resources for teachers like tools and briefs to elicit audience engagement and act as the catalysts for deliberations and discussions.
