A new research paper introduces GRADE, a framework for evaluating the pedagogical capabilities of AI tutors. The study systematically assessed 120 configurations of five language models, exploring methods like zero-shot inference, LoRA fine-tuning, and CoT+Reasoning. Gemma3-12B excelled in single-task evaluations, while Gemma3-27B proved more reliable for multitask predictions. The research also highlighted that while data augmentation can aid struggling models, LoRA fine-tuning may hinder instruction-following in certain modes, and carbon emissions vary significantly with model choice and reasoning approach.
