Summary

KITE (Knowledge-Informed Tutoring Engine) is a Retrieval-Augmented Generation (RAG)-based intelligent tutoring system designed to assist students with algorithmic reasoning and problem-solving in AI education. Presented in the Proceedings of the 21st Workshop on Innovative Use of NLP for Building Educational Applications (BEA 2026) in July 2026, KITE functions as a classroom teaching assistant. It employs an intent-aware Socratic response strategy, delivering targeted hints, guiding questions, and progressive scaffolding to enhance students' algorithmic problem-solving skills. To ensure relevance, KITE utilizes a multimodal RAG pipeline that retrieves information directly from course materials. Evaluation involved RAGAs-based metrics, expert pedagogical review, and a simulated student pipeline where a weaker language model interacted with KITE. Results indicate KITE generates contextually grounded and pedagogically appropriate responses, with its feedback leading to more accurate follow-up answers from simulated students on procedural and tracing questions.

Key takeaway

For AI educators or developers building intelligent tutoring systems, KITE demonstrates a robust approach to enhancing algorithmic problem-solving. You should consider integrating multimodal RAG pipelines to ensure content alignment and adopt intent-aware Socratic strategies for personalized, scaffolded feedback. This method can significantly improve student accuracy on complex procedural and tracing questions, offering a proven framework for future educational AI tools.

Key insights

Retrieval-Augmented Generation (RAG) combined with Socratic strategies can effectively scaffold algorithmic problem-solving in AI education.

Principles

• Intent-aware Socratic responses tailor support to student needs.
• Multimodal RAG pipelines ground tutoring in specific course content.
