Student dropout in distance learning remains a critical challenge, with
profound societal and economic consequences. While classical machine learning
models leverage structured socio-demographic and behavioral data, they often
fail to capture the nuanced emotional and contextual factors embedded in
unstructured student interactions. This paper introduces a transformative AI
framework that redefines dropout prediction through three synergistic
innovations: Retrieval-Augmented Generation (RAG) for domain-specific sentiment
analysis, prompt engineering to decode academic stressors,and cross-modal
attention fusion to dynamically align textual, behavioral, and
socio-demographic insights. By grounding sentiment analysis in a curated
knowledge base of pedagogical content, our RAG-enhanced BERT model interprets
student comments with unprecedented contextual relevance, while optimized
prompts isolate indicators of academic distress (e.g., "isolation," "workload
anxiety"). A cross-modal attention layer then fuses these insights with
temporal engagement patterns, creating holistic risk pro-files. Evaluated on a
longitudinal dataset of 4 423 students, the framework achieves 89% accuracy and
an F1-score of 0.88, outperforming conventional models by 7% and reducing false
negatives by 21%. Beyond prediction, the system generates interpretable
interventions by retrieving contextually aligned strategies (e.g., mentorship
programs for isolated learners). This work bridges the gap between predictive
analytics and actionable pedagogy, offering a scalable solution to mitigate
dropout risks in global education systems
Study at a glance
- Question: Can combining student text analysis with background data through AI better predict dropouts and provide clear explanations for tutors?
- Setting and data: Higher education in Portugal, 4,423 students across multiple academic terms.
- Method: Machine learning model evaluation with ablation study.
Why it matters
Distance education faces high student dropout rates, but existing early warning systems miss emotional signals in student text and produce opaque predictions that tutors find difficult to trust.
Key findings
- The TRIAD-Drop model achieved 89% accuracy and an F1-score of 0.85, outperforming the strongest classical baseline by seven percentage points.
- The model reduced false negatives by 21%, correcting errors largely among students expressing subtle academic distress that classical models missed.
- In a pilot evaluation of alerts, tutors rated the system's generated rationales 4.6 out of 5 for clarity, and mentors accepted 62% of suggested matches.
