Predicting Real-Time Student Engagement in Online Learning Environment Using an Ensemble Model and the GOLD Dataset
摘要
Assessing student engagement in online learning sites is crucial for effectively analyzing student involvement in the course. Given the slow and subjective nature of conventional and self-reporting methods, it has become challenging to understand student engagement. The proposed design of a working model will predict student engagement levels using a novel deep-learning framework. The system employs an ensemble model that takes spatial and temporal features extracted from video clips, with ResNet-18 for spatial feature extraction and ViViT for temporal feature processing. The features are passed through a Multi-layer Perceptron (MLP) for spatial data and Long Short-Term Memory (LSTM) for temporal data. Trained on the new real-time generated dataset, GITAM Online Learning Dataset (GOLD), the model was embedded into a real-time application capable of processing webcam input and predicting engagement every 10 s by averaging results over 5-min windows for deeper insights. Experimental results showed that the ensemble model enhances classification accuracy compared to its counterparts, detecting engagement in real-time. This approach provides a scalable and objective student engagement monitoring solution wherein faculty can identify disengagement early and intervene to improve learning outcomes while circumventing a drawback of traditional methods and giving room for further research on automated engagement detection.
