Summary: In this qualitative study, we explored how oral interviews can inform instructors about students' understanding of abstract algebra and their ability to construct a proof in this setting. Our findings indicate that some student had a good understanding of the ideas needed for a subgroup proof, but could not write a coherent proof. On the other hand, these same students provided fairly sound verbal proofs. We discuss the implications of these results for teaching and future research.
