Situated Practice Systems: Improving and Scaling Coaching through LLMs Authors: Terry Chen, Allyson Lee Abstract Effective coaching in project-based learning environments is critical for developing students’ self-regulation skills, yet scaling high-quality coaching remains a challenge. This paper presents an LLM-enhanced coaching system designed to support project-based learning by helping connect peers struggling with the same regulation gap, and to help coaches by identifying regulation gaps and generating tailored practice suggestions. Our system integrates vector-based semantic matching with LLM-generated regulation gap categorizations for Context Assessment Plan (CAP) notes. Results demonstrate that our system effectively retrieves relevant coaching cases, reducing the cognitive burden on mentors while maintaining high-quality, context-aware feedback. ...
