Socratic benchmark
Dataset Description
The Socratic benchmark is a dataset of tutor-student interactions released by Erfan Al-Hossami et al. (see citations bellow). The dataset released here on HuggingFace for easier training and evaluation of feedback/tutor language models.
Dataset structure
The dataset structure matches the repository structure as released in the GitHub repo. Each subset corresponds to a version, and each split a subrepo in the corresponding version folder.
Languages
The assignments were written in Python.

abstract = {When employing the Socratic method of teaching, instructors guide students toward solving a problem on their own rather than providing the solution directly. While this strategy can substantially improve learning outcomes, it is usually time-consuming and cognitively demanding. Automated Socratic conversational agents can augment human instruction and provide the necessary scale, however their development is hampered by the lack of suitable data for training and evaluation. In this paper, we introduce a manually created dataset of multi-turn Socratic advice that is aimed at helping a novice programmer fix buggy solutions to simple computational problems. The dataset is then used for benchmarking the Socratic debugging abilities of a number of language models, ranging from fine-tuning the instruction-based text-to-text transformer Flan-T5 to zero-shot and chain of thought prompting of the much larger GPT-4. The code and datasets are made freely available for research at the link below.},
