Generative AI offers a scalable way to support the Entrepreneurial Mindset (EM: Curiosity, Connections, and Creating Value) in engineering education, yet many classroom deployments rely on generic chat interfaces that deliver technical answers without prompting EM related reflection. This study evaluates a custom Retrieval Augmented Generation (RAG) chatbot deployed across four engineering courses at a public research university. A distinguishing feature is an optional “EM Info Box” that appends a short, structured metacognitive prompt to selected technical responses. We analyzed n = 3,187 interaction turns from a 16 week semester using log based observational methods. Generalized Estimating Equations modeled the association between EM aligned responses and immediate follow up behavior while accounting for within-student clustering, complemented by a longitudinal analysis of prompt length. Because the EM Info Box is activated by a content based classifier rather than randomized assignment, all reported effects are associative.
Findings indicate that EM aligned scaffolding varies by disciplinary context: in one course, EM aligned turns were associated with lower follow up probability, suggesting single turn informational resolution. In another, ``Creating Value'' triggers reframed technical metrics as expressions of stakeholder value. Longitudinal patterns revealed modest within-student growth in prompt length with a spike near a major deadline. These findings provide behavioral trace evidence of when EM aligned scaffolding appears and how it co-occurs with interaction behaviors, without directly measuring changes in students' underlying mindset.
