MoodleBot Architecture Overview
MoodleBot is a specialized, adaptive LLM-driven chatbot leveraging OpenAI's pretrained models, enhanced by frameworks like LangChain and LlamaIndex. Its design focuses on integrating seamlessly with Moodle to provide tailored feedback and support.
Key components include: Data Acquisition (from PDFs, lecture notes), Data Vectorization (converting data to vectors), storage in a Weaviate database, and a LangChain Agent with Question and Answer Generators. All chat history and costs are stored in a MongoDB instance for transparency and optimization.
Enhancing Self-Regulated Learning (SRL)
MoodleBot significantly aids self-regulated learning (SRL) by offering immediate, contextualized information and support. It helps students set specific goals, monitor performance, and adjust behaviors through cognitive, metacognitive, and motivational strategies.
By providing on-demand explanations and fostering help-seeking behaviors in a private, nonjudgmental space, MoodleBot enables students to resolve knowledge gaps efficiently. This boosts intrinsic motivation and perceived competence, crucial for academic success.
Evaluation & Accuracy Results
The study used the Technology Acceptance Model (TAM) to evaluate MoodleBot's acceptance, revealing high perceived usefulness (PU) and ease of use (PEOU) among students. An overall 88% accuracy rate was observed for course-related assistance, validated by TAs and automated fact-checking.
Despite this, challenges remain in detecting inaccurate statements and the need for more sophisticated fact-checking mechanisms. The positive student perceptions confirm the efficacy and applicability of AI-driven educational tools.
Cost Efficiency Analysis
MoodleBot leverages OpenAI's API platform, with costs calculated based on token usage. The evaluation phase showed an average cost of $1.65 per participant, significantly lower than projected ranges due to partial utilization of the chatbot's full capacity.
This demonstrates a comparable cost-efficiency to similar approaches. For future deployments, employing self-hosted LLMs or more cost-effective models like GPT-3.5-turbo with larger contexts is recommended to maintain economic scalability.
Limitations & Future Work
Limitations include a relatively small sample size (46 students, 30 surveyed) and voluntary participation, potentially introducing selection bias. Manual evaluation by a sole TA also presents a potential for subjective bias.
Future research aims to optimize fact-checking, explore other (self-hosted) LLMs, and expand the user sample for a more robust evaluation. Continuous monitoring and refinement are crucial for maximizing MoodleBot's value in transforming higher education.

Case Study: MoodleBot at RWTH Aachen University
MoodleBot was deployed in a mandatory bachelor's computer science lecture at RWTH Aachen University with over 700 participants. It serves as an interactive platform for students, offering an experience similar to a real tutor with the benefits of immediate responses and 24/7 availability.
The project, part of the tech4compKI initiative, aimed to support personalized learning and skill development through hybrid AI mentoring. The findings underscore MoodleBot's efficacy in providing course-related assistance and improving the overall teaching and learning process, validating the integration of LLM-driven chatbots in academic settings.

Your AI Implementation Roadmap
Navigate the journey of integrating LLM-driven solutions into your educational or enterprise environment with a structured, phase-by-phase approach.
Phase 01: Strategic Planning & Needs Assessment
Define objectives, identify key pain points in current learning/support systems, and assess technical infrastructure readiness for AI integration. Align MoodleBot's capabilities with specific course content and pedagogical goals.
Phase 02: Data Ingestion & Model Configuration
Acquire and vectorize all relevant course materials (lecture notes, slides, exercises) into the Weaviate vector database. Configure LangChain agents with tailored prompts and tools for precise Q&A and exercise generation.
Phase 03: Pilot Deployment & User Training
Integrate MoodleBot into a pilot course within the Moodle LMS. Conduct initial user training for students and educators on MoodleBot's functionalities, emphasizing its role as a supplementary tool for SRL.
Phase 04: Evaluation, Refinement & Scaling
Gather feedback through surveys (e.g., TAM), monitor accuracy, and fact-check responses. Continuously refine the model and prompts based on user data. Explore cost-effective LLM alternatives or self-hosting for wider deployment.
