Agent-Based Synthetic Educational Data Generation for ODL Research

SynthEd: From synthetic data to simulated learners

Agent-based simulation environment for Open & Distance Learning (ODL) research. SynthEd generates behaviorally grounded and temporally coherent learning trajectories by combining persona-driven agent modeling with 11 established theoretical frameworks. Built for researchers in learning analytics, educational data mining, and dropout prediction.

pip install -e ".[dev]"
python run_pipeline.py --n 200

From statistical similarity to behavioral fidelity. Traditional synthetic data methods optimize for distributional match. SynthEd optimizes for behavioral coherence -- each data point emerges from a simulated student's evolving motivations, decisions, and life context.

Why SynthEd?

Challenge	Traditional Approach	SynthEd Approach
Privacy regulations (GDPR/KVKK)	Anonymization (re-identification risk)	Agents are fictional -- no real individuals
Class imbalance in dropout data	Oversampling (SMOTE) -- loses context	Parameter-level control of dropout rates
Temporal incoherence	GAN/VAE post-hoc smoothing	Persona + memory produces coherent trajectories

Key Features

• 11 Theory Modules -- Tinto, Bean & Metzner, Kember, SDT, Garrison CoI, Moore, Rovai, Baulke, Epstein & Axtell, Gonzalez, Unavoidable Withdrawal
• Trait-Based Calibration -- Sobol sensitivity (66 params) + Optuna Bayesian optimization against real OULAD data, validated Grade B on held-out modules
• Multi-Semester Simulation -- Carry-over mechanics for engagement, GPA, coping, dropout phases
• GPA Feedback Loop -- Cumulative GPA anchors cost-benefit, non-fit perception, and competence beliefs
• OULAD-Compatible Export -- 7-table CSV matching the Open University Learning Analytics Dataset schema
• Adaptive Parameter Bounds -- auto_bounds() adjusts calibration space when demographics change
• 5-Level Validation Suite -- 21 statistical tests (distributions, correlations, temporal coherence, privacy, backstory)
• Optional LLM Enrichment -- Persona-grounded narrative backstories via OpenAI, Ollama, or any compatible provider
• 4 Benchmark Profiles -- Developing, Western, Corporate, Mega University with CLI report generation
• InstitutionalConfig -- 5 institution-level quality parameters that modulate theory constants
• NSGA-II Calibration -- Multi-objective optimization with Pareto front exploration
• 565 Tests -- 98% coverage, CI across Python 3.10/3.11/3.12

Quick Start

git clone https://github.com/theaiagent/SynthEd.git
cd SynthEd
pip install -e ".[dev]"
python run_pipeline.py              # 200 students, 14 weeks
python run_pipeline.py --n 500      # Custom population
python run_pipeline.py --oulad      # OULAD-compatible export
python run_pipeline.py --benchmark  # Run all 4 benchmark profiles

from synthed.pipeline import SynthEdPipeline

pipeline = SynthEdPipeline(output_dir="./output", seed=42)
report = pipeline.run(n_students=300)
print(f"Dropout: {report['simulation_summary']['dropout_rate']:.1%}")

Use Cases

1. Dropout Prediction -- Generate labeled training data with known ground-truth trajectories
2. Intervention Simulation -- Model "what-if" scenarios by adjusting population parameters
3. Privacy-Safe Benchmarking -- Share synthetic datasets publicly for reproducible research
