ab: Summary: In this qualitative study, we explored how oral interviews can
inform instructors about studentsâ€™ 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.
