Optimized MAE with PSO-XGBoost
After Particle Swarm Optimization (PSO) for hyperparameter tuning, the Mean Absolute Error (MAE) of the XGBoost model significantly decreased from 0.149 to 0.084. This reduction in prediction error is crucial for practical applications in education, where minimizing the gap between predicted and actual outcomes is highly valued.
Key Influencing Factors
Through SHAP analysis, the study identifies the most significant features influencing MET effectiveness. MET Usage Time emerges as the top factor, showing an inverted U-shaped relationship with learning outcomes, followed by Mathematics Topics and Teaching Content 1. This emphasizes the importance of calibrated technology use and well-structured curriculum design.
MET Usage Time: The Critical Factor
SHAP analysis revealed that MET Usage Time is the most influential feature, accounting for 48.5% of the total importance. The data suggests an inverted U-shaped relationship, where both insufficient and excessive exposure to MET reduce its benefits. Optimal usage duration maximizes learning outcomes, highlighting the need for calibrated integration of technology in teaching.
48.5%
MET Usage Time Contribution
MET Usage Time is identified as the most dominant factor impacting student learning outcomes with MET. This underscores the need for precise calibration rather than blanket implementation, aligning technology use with pedagogical goals.
Other Significant Predictors
Mathematics Topics (9.5%) and Teaching Content 1 (8.6%) are also highly influential. Basic mathematical concepts and geometry-focused content show stronger positive impacts. Mathematical Abilities (8.5%) and Sample Size (8.3%) further contribute, emphasizing the importance of problem-solving skills and robust study design. Grade Level (4.0%) showed that younger students benefited more.Real-World Validation & Equity
The predictive model's efficacy is validated through a controlled experiment in a Mainland China middle school, demonstrating that model-guided MET significantly outperforms traditional teaching. This validation confirms the model's practical applicability and generalizability, promoting educational equity by providing novice teachers with evidence-based guidance to optimize MET usage.
Controlled Experiment: Model-Guided MET Superiority
A controlled experiment in a Mainland China middle school validated the AI model. Experimental groups using model-guided MET for 18 teaching periods showed significantly higher student achievement compared to control groups and indirect control groups (14 periods based on experience). This confirms the model's practical utility in optimizing MET implementation and improving learning outcomes.
