Neural-Symbolic Knowledge Tracing: Injecting Educational Knowledge into Deep Learning for Responsible Learner Modelling
Summary
Responsible-DKT is a novel neural-symbolic deep knowledge tracing approach designed to enhance learner modeling in AI-driven education. This method integrates symbolic educational knowledge, such as mastery and non-mastery rules, into sequential neural models. Evaluated on a real-world dataset of student math interactions, Responsible-DKT significantly outperforms both a neural-symbolic baseline and a fully data-driven PyTorch DKT model. It achieves over 0.80 AUC with only 10% of training data and up to 0.90 AUC, representing a performance improvement of up to 13%. The model also exhibits superior temporal reliability, showing lower prediction errors in early and mid-sequences and reduced prediction inconsistency rates across various sequence lengths. Additionally, Responsible-DKT offers intrinsic interpretability through a grounded computation graph, which exposes the logic behind each prediction and facilitates both local and global explanations.
Key takeaway
For AI scientists and machine learning engineers developing intelligent tutoring systems, Responsible-DKT demonstrates that integrating symbolic educational knowledge into deep learning models can significantly boost predictive performance and interpretability. You should consider adopting neural-symbolic architectures to improve temporal reliability, mitigate data scarcity, and provide transparent explanations for learner predictions, fostering more responsible AI in education.
