| dc.description.abstract | Subscription-based educational technology (EdTech) companies face significant revenue loss due to customer churn, making retention vital. Retaining engaged learners is generally more cost-effective than acquiring new ones. This study develops a predictive churn model using anonymised student data from Company X, an EdTech platform for children’s English learning, covering the period from April 2024 to February 2025. The real name of the company has been intentionally left out to ensure confidentiality. Following a CRISP-DM process, student activity, engagement, and financial features were engineered over multiple time windows, capturing evolving student behaviours. Four machine learning (ML) algorithms - logistic regression (LR), random forest (RF), neural networks (NN), and XGBoost (XGB) - were trained and compared, employing resampling techniques (RUS+SMOTE) to address class imbalance. The optimised XGB model achieved the best performance, with approximately 0.84 accuracy, 0.63 F1 score, 0.85 recall, and the area under the curve (AUC) of 0.85 on test data, effectively identifying likely churners. Shapley Additive exPlanations (SHAP) based analysis revealed that engagement metrics, particularly the number of paid classes (both current and mean over 8 weeks), total learning time, engagement at gamified features, and customer tenure, were the most influential predictors, confirming that highly engaged students are less likely to churn. This interpretable model provides actionable insights for retention strategies by predicting individual churn risk and highlighting key engagement drivers. Practically, even a 1% monthly reduction in churn could translate to multi-million-dollar annual savings for subscription EdTech providers. Overall, this research extends churn prediction into the EdTech domain, demonstrates the value of long-term engagement features, and applies explainable AI to enhance model transparency, thereby supporting its practical adoption. | pt_PT |
