  Generative AI has shown potential in solving physics problems and providing
feedback on assessments. However, results are sometimes still inaccurate, at
the wrong level, or using notations and definitions not appropriate for a
particular course. A possible solution is augmenting the prompts with
course-specific reference materials. Also, for feedback on homework solutions
and grading exams, the problem text and the sample solution or grading rubric
can be injected into the prompts. Project Ethel at ETH Zurich aims to construct
a virtual teaching assistant using these practices.
