Feature Request Description
Summary
Enhance DeepTutor's learning experience by implementing multimodal content generation and strategic personalization, inspired by Google Research's "Learn Your Way" framework. This addresses the current limitation of passive document retrieval by transforming static content into multiple interactive learning formats tailored to individual learners.
Background & Motivation
Google's recent research Learn Your Way: Reimagining textbooks with generative AI demonstrated:
- 11% improvement in retention scores
- 100% student comfort ratings
- Grounded in dual coding theory: multiple representations strengthen conceptual understanding
DeepTutor currently excels at document Q&A and visualization, but could evolve from a "smart retrieval system" into a true adaptive learning platform by generating multiple content representations from uploaded materials/knowledge base.
Proposed Features
1. Five Multimodal Content Representations
Transform uploaded documents (textbooks, papers, manuals) into:
Immersive Text
- Break content into digestible sections with auto-generated pedagogical images
- Embed comprehension questions throughout
- Transform passive reading into active multimodal experiences
Narrated Slides
- Generate full presentation decks from source material
- Include interactive activities (fill-in-the-blanks, concept checks)
- Add optional AI-narrated audio versions mimicking recorded lessons
Audio Lessons
- Create simulated teacher-student conversations
- Include common misconceptions and their clarifications
- Provide alternative learning pathway for auditory learners
Mind Maps
- Organize knowledge hierarchically from uploaded content
- Enable zoom navigation between big picture and granular details
- Visual representation of concept relationships
Interactive Videos (Future Enhancement)
- Animated concept explanations
- Pause points with embedded assessments
2. Strategic Personalization Pipeline
Implement a two-layer personalization system:
Layer 1: Complexity Re-leveling
- Automatically adjust content difficulty based on user's knowledge level
- Maintain scope while simplifying/enriching explanations
- Integrate with existing Knowledge Graph for prerequisite tracking
Layer 2: Interest-Based Contextualization
- Collect user interests during onboarding (sports, music, food, technology, etc.)
- Replace generic examples with personalized ones throughout all representations
- Example: Statistics concepts explained through basketball analytics for sports enthusiasts
3. Fine-Tuned Educational Image Model
Current general-purpose image models aren't optimized for pedagogical illustrations.
Implementation approach:
- Fine-tune a dedicated model specifically for educational visuals
- Train on datasets like OpenStax illustrations, academic diagrams, technical schematics
- Integrate with existing visualization pipeline
- Prioritize clarity, accuracy, and instructional value over aesthetic appeal
4. Dynamic Feedback & Adaptive Pathways
Enhance the existing Practice Problem Generator with:
- Struggle area tracking: Monitor which topics/questions users get wrong
- Adaptive content routing: Automatically suggest revisiting specific representations (e.g., "Try the audio lesson for this concept")
- Personalized review sessions: Generate targeted practice based on knowledge gaps
- Progress visualization: Show mastery improvements over time
5. Pedagogy-Infused Model Integration
- Integrate pedagogy-specific capabilities (similar to Google's LearnLM)
- Enhance existing multi-agent workflows with educational best practices
- Add explicit instructional design prompts to content generation agents

- Memory System: Persist personalization profiles and learning progress
- Multi-Agent System: Add specialized agents for each content format
- Tool Integration Layer: Extend with educational image generator and TTS
Expected Benefits
- Improved retention: Multiple representations leverage dual coding theory
- Higher engagement: Personalized examples increase relevance
- Accessibility: Multiple formats accommodate different learning styles
- Reduced cognitive load: Right-sized complexity prevents overwhelm
- True adaptive learning: Dynamic feedback creates personalized pathways
Implementation Priority
Phase 1 (High Priority)
- Immersive text generation
- Basic personalization pipeline (complexity adjustment)
- Dynamic feedback system integration
Phase 2 (Medium Priority)
- Narrated slides generation
- Interest-based contextualization
- Mind map generation
Phase 3 (Future)
- Audio lesson generation (requires TTS like Qwen 3)
- Fine-tuned educational image model
- Interactive video generation

Additional Notes
This enhancement positions DeepTutor beyond competitors by combining:
- Massive document processing (current strength)
- Multi-agent intelligence (current strength)
- Multimodal generation (new capability)
- Deep personalization (new capability)
The result: A truly adaptive learning system that doesn't just answer questions, but actively teaches in the way each student learns best.
