TinyTorch Module Analyzer & Report Card Generator

A comprehensive, reusable tool for analyzing educational quality and generating actionable report cards for TinyTorch modules.

🎯 Purpose

This tool automatically analyzes TinyTorch modules to:

• Identify student overwhelm points (complexity cliffs, long cells, missing guidance)
• Grade educational scaffolding (A-F grades for different aspects)
• Generate actionable recommendations for improvement
• Compare modules to find best and worst practices
• Track progress over time with quantitative metrics

🚀 Quick Start

# Analyze a single module
python tinytorch_module_analyzer.py --module 02_activations

# Analyze all modules
python tinytorch_module_analyzer.py --all

# Compare specific modules
python tinytorch_module_analyzer.py --compare 01_tensor 02_activations 03_layers

# Generate and save detailed reports
python tinytorch_module_analyzer.py --module 02_activations --save

📊 What It Analyzes

Educational Quality Metrics

• Scaffolding Quality (1-5): How well the module supports student learning
• Complexity Distribution: Percentage of high-complexity cells
• Learning Progression: Whether difficulty increases smoothly
• Implementation Support: Ratio of hints to TODO items

Content Metrics

• Module Length: Total lines and cells
• Cell Length: Average lines per cell
• Concept Density: Concepts introduced per cell
• Test Coverage: Number of test files

Student Experience Factors

• Overwhelm Points: Specific issues that could frustrate students
• Complexity Cliffs: Sudden difficulty jumps
• Missing Guidance: Implementation cells without hints
• Long Cells: Cells that exceed cognitive load limits

📈 Report Card Grades

Overall Grade (A-F)

• A: Excellent scaffolding, smooth progression, student-friendly
• B: Good structure with minor issues
• C: Adequate but needs improvement
• D: Significant scaffolding problems
• F: Major issues, likely to overwhelm students

Category Grades

• Scaffolding: Quality of learning support and guidance
• Complexity: Appropriateness of difficulty progression
• Cell_Length: Whether cells are digestible chunks

🎯 Target Metrics

The analyzer compares modules against these educational best practices:

Metric	Target	Why It Matters
Module Length	200-400 lines	Manageable scope for students
Cell Length	≤30 lines	Fits cognitive working memory
High-Complexity Cells	≤30%	Prevents overwhelm
Scaffolding Quality	≥4/5	Ensures student support
Hint Ratio	≥80%	Implementation guidance

🔍 Sample Output

🔍 Analyzing module: 02_activations

📊 Report Card for 02_activations:
Overall Grade: C
Scaffolding Quality: 3/5
Critical Issues: 2

Critical Issues Detected

• Too many high-complexity cells (77%)
• Implementation cells lack guidance (40% without hints)
• Sudden complexity jumps will overwhelm students
• 3 cells are too long (>50 lines)

Recommendations

• Add implementation ladders: break complex functions into 3 progressive steps
• Add concept bridges: connect new ideas to familiar concepts
• Split 3 long cells into smaller, focused cells
• Add hints to 4 implementation cells

🔄 Workflow Integration

Before Making Changes

# Get baseline metrics
python tinytorch_module_analyzer.py --module 02_activations --save

After Improvements

# Check improvement
python tinytorch_module_analyzer.py --module 02_activations --save
# Compare with previous reports to track progress

Continuous Monitoring

# Check all modules regularly
python tinytorch_module_analyzer.py --all --save

🎓 Educational Framework

The analyzer is based on proven educational principles:

Rule of 3s

• Max 3 complexity levels per module
• Max 3 new concepts per cell
• Max 30 lines per implementation cell

Progressive Scaffolding

• Concept bridges: Connect unfamiliar to familiar
• Implementation ladders: Break complex tasks into steps
• Confidence builders: Early wins build momentum

Cognitive Load Theory

• Chunking: Information in digestible pieces
• Progressive disclosure: Introduce complexity gradually
• Support structures: Hints and guidance when needed

🛠️ Customization

Modify Target Metrics

Edit the target_metrics in the TinyTorchModuleAnalyzer class:

self.target_metrics = {
    'ideal_lines': (200, 400),
    'max_cell_lines': 30,
    'max_complexity_ratio': 0.3,
    'min_scaffolding_quality': 4,
    'max_concepts_per_cell': 3,
    'min_hint_ratio': 0.8
}

Add Custom Analysis

Extend the analyzer with domain-specific metrics for your educational context.
