Decoding Student Minds: Leveraging Conversational Agents for Psychological and Learning Analysis
This addresses the need for integrated psychological and learning support in educational settings, though it appears incremental by combining existing methods for a specific application.
The paper tackled the problem of analyzing students' cognitive and affective states in education by developing a conversational agent that uses multimodal data, resulting in improved motivation, reduced stress, and moderate academic gains in a pilot study.
This paper presents a psychologically-aware conversational agent designed to enhance both learning performance and emotional well-being in educational settings. The system combines Large Language Models (LLMs), a knowledge graph-enhanced BERT (KG-BERT), and a bidirectional Long Short-Term Memory (LSTM) with attention to classify students' cognitive and affective states in real time. Unlike prior chatbots limited to either tutoring or affective support, our approach leverages multimodal data-including textual semantics, prosodic speech features, and temporal behavioral trends-to infer engagement, stress, and conceptual understanding. A pilot study with university students demonstrated improved motivation, reduced stress, and moderate academic gains compared to baseline methods. These results underline the promise of integrating semantic reasoning, multimodal fusion, and temporal modeling to support adaptive, student-centered educational interventions.
