AI-Powered Conversational Tutoring
The framework integrates Large Language Models (LLMs) as an AI chatbot tutor, designed for on-demand clarification, Socratic questioning, misconception diagnosis, and metacognitive prompting. It leverages models like GPT-4, with a robust architecture for context management and prompt engineering. Crucially, the system incorporates strict safeguards against hallucination, including calculation verification by a separate engine, Retrieval-Augmented Generation (RAG) for factual claims, and human escalation protocols for complex or sensitive issues.
Interactive Simulation-Based Learning
Simulation modules are a core component, externalizing abstract probabilistic relationships into visual and manipulable representations. Students interact with load and resistance distributions, observe failure probabilities, and adjust parameters in real-time. This hands-on approach helps build intuition for concepts like uncertainty, variability, and reliability indices, which are difficult to grasp purely from text. Simulations are carefully scaffolded to guide exploration without overwhelming students with unnecessary complexity.
Theoretical Foundations & Threshold Concepts
The framework is grounded in multiple learning theories: Cognitive Load Theory guides the scaffolded progression, Multimedia Learning Principles inform simulation design, Zone of Proximal Development and Scaffolding shape the AI tutor's adaptive support, and Self-Regulated Learning is fostered through metacognitive prompts. Critically, it addresses probabilistic reasoning as a Threshold Concept for civil engineering, recognizing its transformative, troublesome, and irreversible nature, providing a safe space for students to challenge deterministic assumptions.
Threshold Concept
Probabilistic Reasoning as a Core Barrier

Illustrative Scenario: Transforming Deterministic Mindsets
A student, expecting zero failure with a Safety Factor (SF) of 2.0 in deterministic analysis, uses Module 3's simulation. They observe an overlap region and a non-zero failure probability (Pf ≈ 2.3 × 10−3) despite mean resistance being double the mean load. Surprised, they ask the AI chatbot: "Why is failure still possible?" The chatbot, using Socratic prompts, guides the student to recognize that variability, not just averages, determines the probability of unfavorable combinations. This interaction helps the student construct a deeper, probabilistic understanding, moving beyond their prior deterministic assumptions.
Key Takeaway: This illustrates the framework's ability to make probabilistic consequences visible through simulation, supported by Socratic guidance from the AI tutor, facilitating a genuine conceptual shift.
