Moodle Block uteluqchatbot

The uteluqchatbot plugin is a Moodle block plugin designed to enhance distance learning by providing an adaptive and innovative chatbot solution. Integrated into the Moodle platform, it supports three distinct user roles—Learner, Teacher, and Administrative Manager—to facilitate course interactions, content management, and plugin configuration. This plugin leverages Retrieval-Augmented Generation (RAG) to deliver precise, context-aware responses based on course materials, improving the learning experience for users.

Maturity

• The plugin is in alpha version currently. We have validated it internally on a test server but it may still contain significant bugs. We do not currently recommend the plugin for production use.

Supported Languages

The plugin currently supports the following languages:

• French (fr)


• English (en)


• Arabic (ar)


• Danish (da)


• German (de)


• Haitian Creole (ht)


• Hindi (hi)


• Italian (it)


• Japanese (ja)


• Polish (pl)


• Portuguese (pt)


• Russian (ru)


• Swahili (sw)


• Chinese (Simplified) (zh_cn)

Features

Learner Role

• Interactive Q&A: Learners can ask questions about course content, receive clarifications, revise exercises, and get study method suggestions via a user-friendly interface.


• Contextual Responses: With RAG enabled, the chatbot provides accurate, course-specific answers by retrieving relevant information from uploaded course materials.

Teacher Role

• Course Upload: Teachers can upload multiple PDF course resources simultaneously, which the chatbot uses to generate informed responses.


• Prompt Customization: Teachers can modify the default prompt to tailor the chatbot’s behavior, supported by a provided Prompt Design Guide.


• Testing Functionality: Teachers can test the chatbot by posing questions to verify its performance with uploaded resources.

Administrative Manager Role

• Plugin Configuration: Admins configure the plugin via Moodle’s site administration interface, setting up API keys for services like Cohere, Adobe PDF Services, and Weaviate.


• Seamless Integration: The plugin is accessible under the "Plugins" section of Moodle’s admin panel for easy management.

RAG Integration

• With RAG: Enhances response accuracy, relevance, and completeness by retrieving course-specific data from a vector database before generating answers.


• Without RAG: Provides general responses based on the model’s internal knowledge, suitable for quick interactions but less precise for course-specific queries.

Installation

Download the Plugin:

• Clone the repository: git clone https://github.com//moodle-block_uteluqchatbot.git


• Or download the ZIP file from the Moodle Plugins Directory (once published).

Install in Moodle:

• Copy the uteluqchatbot folder to the /blocks/ directory of your Moodle installation.

Testing and Validation

The plugin has been rigorously tested in both academic and AWS cloud environments to ensure robustness and scalability (see project report, Section 2). Key findings include:

• RAG Mode: Outperforms non-RAG mode in precision, relevance, completeness, and pedagogical utility, with clear, context-aware responses and no noticeable latency.


• Non-RAG Mode: Offers satisfactory clarity and speed but may provide less accurate or overly general responses for course-specific queries.

A detailed testing protocol will be published, with evaluation criteria including:

• Precision, relevance, clarity, and completeness of responses.


• Response time, dialogue coherence, and pedagogical utility.


• Comparative testing with and without RAG, using provided course PDFs.

Requirements

• Moodle Version: Compatible with Moodle [specify version, e.g., 4.1+] (ensure compatibility with maintained versions as per Moodle Releases).
