HKUDS releases DeepTutor v1.5, an open-source, agent-native personalized tutoring platform that integrates chat, quiz, research, visualization, and mastery practice into a unified runtime with inspectable memory and extensible tools.
MOSAIC is a novel framework that uses a frozen LLM to generate semantic embeddings and hierarchical prediction prompts for knowledge tracing, achieving state-of-the-art results on multiple benchmarks.
This paper introduces SLC (State-space Logit Correction), which corrects per-item logit bias in knowledge tracing models using empirical-Bayes shrinkage via a Kalman smoother, improving AUC beyond global calibration techniques.
Researchers introduce a new multimodal benchmark derived from Japan's National Assessment of Academic Ability, featuring 900K aggregated student responses to evaluate MLLM performance in authentic K-12 educational contexts.
This paper presents a hybrid framework for detecting alarming or distressed student verbal responses by combining a text classifier (content-based) and an audio classifier (prosodic features), aimed at expediting human review in Automated Verbal Response Scoring systems. The approach addresses a safety gap in automated scoring pipelines where at-risk student responses may otherwise go unnoticed.
