Advancing AI for Education through LLMs and Probabilistic Modeling of Student Learning!

About Me

I am a Ph.D. student in Computer Science at the University of Memphis and a Graduate Assistant under Dr. Deepak Venugopal. My research investigates the use of large language models (LLMs) to model and simulate student learning behaviors, integrating BERT and Deep Knowledge Tracing within intelligent tutoring systems in collaboration with Carnegie Learning. To learn more about my research, please visit ASTRA

My work has been accepted at LAK (Learning Analytics and Knowledge Conference) and is aimed at venues such as AIED (Artificial Intelligence in Education) and Learning@Scale.

This work investigates how students employ multiple mathematical strategies, such as Equivalent Ratios (ER) and Means & Extremes (ME), in the MATHia intelligent tutoring environment. We present a BERT-based model fine-tuned on student action sequences and Deep Knowledge Tracing (DKT) for predicting next-strategy use and hint behavior. The study offers empirical insights into student learning dynamics and contributes to the development of interpretable AI models for education.
