An Educator-Guided LLM Pedagogical Agent for Scaffolded Feedback in Conceptual Database Design

Read the original on arXiv AI →

The paper introduces an educator‑guided large language model (LLM) pedagogical agent that provides scaffolded feedback for conceptual database design. Embedded in an entity–relationship diagram editor, the system bases its feedback on the student’s artifact, assignment requirements, educator‑authored rubrics, and instructional resources, using a four‑stage workflow that progresses from concept checks to low‑detail feedback and localized clarification. In a deployment across three ERD environments with 383 feedback episodes, 71.1% of target‑level changes incorporated the hidden diagnostic target, and qualitative analysis highlighted the benefits and challenges of staged disclosure.

On the Limitations of Large Language Models for Conceptual Database Modeling

The article examines how Large Language Models can aid in creating Entity-Relationship diagrams from natural language requirements. It tests three LLMs with three prompting strategies—Zero-Shot, Chain of Thought, and Chain of Thought + Verifier—on scenarios of increasing complexity. Findings show that while LLMs perform adequately on simpler tasks, their reliability drops with more complex requirements, leading to inconsistencies, ambiguities, and constraint representation failures.

RegulaTutor: A Theory-Informed Framework for Long-Term Personalized Learning

RegulaTutor is a theory-informed framework for long‑term personalized tutoring that links a learner’s historical evidence to instructional support. Guided by self‑regulated learning research, it uses a cognitive, affective, metacognitive, and motivational (CAMM) framework to derive evidence‑supported learner interpretations and teaching policies that are updated as new observations arrive. The framework includes PairRoute, an offline refinement procedure that distinguishes harness, model, and mixed failures, proposes targeted harness revisions, and constructs stage‑level supervision for confirmed model failures, improving historical‑evidence accuracy, learner diagnosis, and teaching quality across evaluated model configurations.
