# Educational Activities Implementation - Complete

## Project Summary

**Status**: ✅ COMPLETED
**Total Activities Created**: 8 (activity30 - activity37)
**Total Lines of YAML**: 6,112
**Validation Status**: All activities passing with 0 errors

## Design Criteria (Achieved)

All activities successfully implemented with:
1. ✅ **No embedded Python** - Pure YAML using buckets, transitions, metadata operations, AI feedback
2. ✅ **Educational value** - Teach concepts through interaction and reflection
3. ✅ **Engaging** - Mix of narrative, problem-solving, and critical thinking
4. ✅ **Progressive** - Build knowledge step-by-step
5. ✅ **Use AI effectively** - Separate classifier and feedback models for optimal performance
6. ✅ **Follow schema** - All activities validated successfully

## New Feature: Model Configuration

All activities now support configurable AI models:

```yaml
# Activity-level defaults
classifier_model: "MODEL_1"  # Fast classification (Hermes-3-Llama-3.1-8B)
feedback_model: "MODEL_1"    # Feedback generation (can override per activity)

# Step-level overrides (optional)
- step_id: "code_review"
  classifier_model: "MODEL_1"  # Keep Hermes for classification
  feedback_model: "MODEL_3"    # Use Qwen3-Coder for code feedback
```

### Model Recommendations

- **MODEL_1 (Hermes-3-Llama-3.1-8B)**:
  - Default for all activities
  - Always available in base install
  - Excellent for role-playing scenarios
  - Fast and accurate classification
  - Great general-purpose feedback

- **MODEL_3 (Qwen3-Coder-30B)**:
  - Specialized for programming (activity37)
  - Recommended: `hf.co/unsloth/Qwen3-Coder-30B-A3B-Instruct-GGUF:Q4_K_M`
  - Supports 100+ programming languages
  - Expert code generation and debugging

## Completed Activities

### Initial Set (Activities 30-34)

| Activity | Lines | Topic | Status | Special Features |
|----------|-------|-------|--------|-----------------|
| **30** | 530 | Logic Puzzles | ✅ | Contrapositive, syllogisms, knights and knaves |
| **31** | 651 | Scientific Method | ✅ | Historical case studies (Semmelweis, Newton) |
| **32** | 796 | World Geography | ✅ | Choose-your-own-adventure, metadata path tracking |
| **33** | 640 | Environmental Science | ✅ | Role-play as consultant, environmental score tracking |
| **34** | 697 | Media Literacy | ✅ | Source evaluation, bias detection, fact-checking |

### Extended Set (Activities 35-37)

| Activity | Lines | Topic | Status | Special Features |
|----------|-------|-------|--------|-----------------|
| **35** | 981 | American History | ✅ | Advanced for gifted students, primary source analysis |
| **36** | 877 | Biblical History | ✅ | Historical/archaeological approach, ancient Near East |
| **37** | 700 | Programming Languages | ✅ | **Universal language support**, MODEL_3 (Qwen3-Coder) |

### Activity 37: Programming Languages (Flagship)

**Innovation**: First activity to leverage dual-model configuration

```yaml
classifier_model: "MODEL_1"  # Hermes for fast bucketing
feedback_model: "MODEL_3"    # Qwen3-Coder for code generation
```

**How it works**:
1. Student chooses ANY programming language (Python, Rust, COBOL, etc.)
2. Choice stored in metadata: `programming_language: "user-choice"`
3. AI adapts ALL code examples to chosen language via `tokens_for_ai`
4. Qwen3-Coder generates language-specific syntax and explanations
5. Covers: Hello World, variables, control flow, loops, functions (all using stdout)

## Technical Architecture

### YAML-Only Features Used

- **Buckets**: Response categorization (correct, partial_understanding, off_topic)
- **Transitions**: Navigation between steps based on buckets
- **Metadata Operations**:
  - `metadata_add`: Persistent state
  - `metadata_tmp_add`: Single-turn state
  - `metadata_remove`: State cleanup
  - `metadata_clear`: Reset all state
- **AI Feedback**:
  - `tokens_for_ai`: Classification instructions
  - `feedback_tokens_for_ai`: Feedback generation instructions
  - `tokens_for_ai_rubric`: Final evaluation rubric
- **Model Selection**:
  - `classifier_model`: Per-activity or per-step classification model
  - `feedback_model`: Per-activity or per-step feedback model

### Validation

All activities pass validation:
```bash
python activity_yaml_validator.py research/activity*.yaml
# Result: 8 files, 0 errors, 0 warnings
```

### Testing

CLI simulation tool supports model configuration:
```bash
source vars.sh
python research/guarded_ai.py research/activity37-programming-languages.yaml
# Uses MODEL_1 for classification, MODEL_3 for code feedback
```

## Key Implementation Decisions

### Why Separate Classifier and Feedback Models?

1. **Speed**: Classification is fast (Hermes 8B) → instant response bucketing
2. **Quality**: Feedback can use specialized models → better explanations
3. **Cost**: Don't need large model for simple categorization
4. **Flexibility**: Override per-step for specific needs

### Why Hermes as Default?

1. **Availability**: Always included in base install
2. **Speed**: 8B model is very fast
3. **Quality**: Excellent at role-playing and general tasks
4. **Reliability**: Stable fallback for all activities

### Why Qwen3-Coder for Programming?

1. **Specialization**: Trained specifically for code generation
2. **Language Coverage**: Supports 100+ programming languages
3. **Size**: 30B parameters → much smarter than 8B models
4. **Accuracy**: Better at language-specific syntax and idioms

## Usage Examples

### Run an Activity (Web App)
```bash
source vars.sh
python app.py
# Navigate to http://localhost:5000
# Select activity from dropdown
```

### Test an Activity (CLI)
```bash
source vars.sh
python research/guarded_ai.py research/activity37-programming-languages.yaml
# Choose: Rust
# Activity adapts all examples to Rust syntax
```

### Validate All Activities
```bash
python activity_yaml_validator.py research/activity*.yaml
```

## Future Enhancements

### Potential Model Combinations

1. **Fast Classification + Quality Feedback**:
   ```yaml
   classifier_model: "MODEL_1"  # Hermes 8B (fast)
   feedback_model: "MODEL_2"    # Larger model (quality)
   ```

2. **Domain-Specific Models**:
   - Science activities → Science-tuned model
   - History activities → Long-context model
   - Code activities → Code-specialized model

3. **Step-Level Overrides**:
   ```yaml
   - step_id: "creative_writing"
     feedback_model: "MODEL_4"  # Creative writing specialist

   - step_id: "code_review"
     feedback_model: "MODEL_3"  # Code specialist
   ```

## Lessons Learned

1. **Metadata is Powerful**: Can track complex state without Python
2. **AI Adaptation**: `tokens_for_ai` enables universal activities (any language)
3. **Model Separation**: Classification vs feedback needs different models
4. **Hermes Excellence**: Great for role-playing scenarios (consultant, teacher)
5. **Validation Critical**: Schema validation caught all errors early
