Studying Impact and Intent of Design: Conjecture Mapping for Affect-Centered Analysis

Physics education researchers have argued that authentic physics education includes computation as part of a physics student's training, and many parties have made efforts towards this goal. However, most research on this teaching modality has centered cognitive impacts rather than affective impacts, so little is known about the affective outcomes of holistically integrating computation into physics courses. To address that need, we present a case study of a multi-day activity within a computationally integrated modern physics laboratory course. With data from ethnographic course observations and semi-structured interviews, we introduce a novel modification of conjecture mapping to distinguish between the professor's intent behind the activity design and the impact on a student's physics computational literacy and physics identity. In doing so, we highlight the methodological suitability of conjecture mapping for comparing the intent and impact of curricular design and explicate the specific misalignments that led to different affective outcomes than intended.

Same Activity, Divergent Impacts: Representing Paths Towards Physics Computational Literacy and Physics Identity with Conjecture Mapping-Based Narrative Analysis

Integrating computation into physics teaching is a curricular move that, at present, has been predominately studied for its cognitive impacts. However, if this modality of instruction shifts how students engage with physics, we argue there is room for students to redefine what it means to do physics and how they perceive themselves relative to the field. To investigate this, we situate a comparative case study in the context of a computationally integrated physics course. We study two students' experiences with a multi-day activity to understand how and why they came to affectively divergent self-perceptions. We propose a modified use of conjecture mapping to visualize the production of affective outcomes and connect narrative analysis to activity design. Our analysis highlights how different interpretations of and engagement with activity design reflect students' epistemic framing of code, which, in turn, drives engagement with scaffolding in manners that shape self-perception.
