Chatbot Conversations in Physics Education: Using Artificial Intelligence to Analyze Student Reasoning through Computational Grounded Theory
Revolutionizing Physics Education with AI-Powered Insights
This study introduces a novel application of Computational Grounded Theory (CGT) to analyze student interactions with an AI chatbot, the UTA Study Buddy Bot, in a university-level Modern Physics course. By processing over 10 million tokens of student dialogue, the research identifies recurring misconceptions and reasoning patterns at scale. This approach not only provides deep insights into student understanding of complex topics like relativistic momentum and quantum energy levels but also offers a scalable, cost-effective, and reproducible methodology for qualitative educational research. The findings demonstrate the power of AI to transform educational support into a rich data source for pedagogical innovation, paving the way for more adaptive and AI-driven learning tools.

Relativistic Energy Confusion
Student difficulties with special relativity, especially distinguishing between rest mass energy, total energy, and relativistic kinetic energy. Messages commonly included phrases like 'mass MeV rest' and 'at 0.7c', indicating a reliance on formula-based reasoning but often with conceptual mix-ups.
Example:- An electron is moving at 0.7c...
Infinite Square Well Transitions
Student questions about photon emission during transitions between discrete energy levels in an infinite square well. Representative words like 'wavelength', 'photon', and 'electron' appeared frequently, but students often misapplied energy level indices or misunderstood quantum number labeling.
Example:- What is the energy of a photon from n=3 to n=1?
Schrödinger Equation Interpretation
Theoretical questions about the one-dimensional Schrödinger equation, including the role of potential energy and the equation's components. Often phrased in abstract or conceptual terms.
Example:- How does increasing the width of a potential barrier in the one-dimensional Schrödinger's finite potential well affect the probability of finding the particle on the other side of the barrier?

Fall 2024 Modern Physics Course: UTA Study Buddy Bot
The AI-powered chatbot was deployed in a fully asynchronous, university-level Modern Physics course. Students used it for homework, exam preparation, and conceptual understanding, generating over 10 million tokens of interaction data. The chatbot used RAG techniques and provided Socratic-style explanations.
Key Findings:
- High Engagement Peaks: Chatbot usage surged around midterm and final exams, indicating students relied on AI support during peak academic pressure.
- Diverse Misconceptions Identified: CGT revealed persistent conceptual difficulties in relativistic momentum, quantum energy levels, and Schrödinger equation interpretation, articulated in students' natural language.
- Cost-Effective Support: The chatbot supported students throughout the semester at a low cost of $2.85 per student, demonstrating scalability and affordability for large enrollment courses.
Implication: This case study validates the utility of AI chatbots as both instructional tools and powerful data collection instruments for PER, enabling scalable analysis of student reasoning.
