Automatic feedback on physics tasks using open-source generative artificial intelligence

This study explores the feasibility of using open-source large language models (LLMs) to generate automatic feedback on physics problem-solving tasks in educational settings. A quantised version of the open-source LLM OpenChat 3.6 was employed to generate German-language feedback for high school students on standard school hardware. The study procedure involved five stages: data preparation, model selection, prompt design, response evaluation, and quality analysis of feedback. OpenChat 3.6 achieved an accuracy of 0.84 in classifying student answers. In comparison, GPT4-o achieved an accuracy of 0.85. The open-source LLM provided accurate and
