Abstract
Measuring students’ sense of belonging, characterized by feelings of acceptance, inclusion, and encouragement from teachers, remains a significant challenge in computing education. Prior research has associated this multidimensional construct with positive academic outcomes and has identified instructors’ growth- and fixed-mindset messaging as a potential influence. However, belonging is a complex and deeply personal experience that is difficult to capture through direct observation alone. Current measurement methods rely on self-report surveys, which may not capture every aspect of an experience that can also involve emotional and cognitive responses.
This thesis investigates whether combining EEG data recorded during a belonging questionnaire with survey responses can improve the classification of students’ sense of belonging in computing education. Supervised multimodal machine learning models were constructed using several label-construction approaches derived from student survey responses. Multiple EEG representations were explored, including raw signals and two-dimensional scalograms. Because EEG-based machine learning is challenged by noisy recordings and limited training data, data augmentation was applied to the scalogram representations to improve model generalization. CNN-LSTM, CNN-GRU, and ChronoNet architectures were evaluated on these inputs, with the multimodal 2D CNN-GRU model achieving the strongest performance at an accuracy of 87.5% compared with its corresponding survey-only baseline of 80.0%. These findings offer preliminary evidence that EEG may provide complementary information and support more comprehensive approaches to understanding belonging in computing education.
