It is great to hear about efforts to teach AI literacy, particularly for non-technical people. There is ongoing academic debate on whether one can teach AI literacy to undergraduate students across majors, and if yes, how. This article reports a case study: a three-week midterm project embedded in an undergraduate “AI-for-all” course. Students designed reasoning tasks, ran controlled comparisons across widely used chatbots, and evaluated both answer correctness and explanation validity. Through field experience, students with no STEM background learned what consumer chatbots can and cannot do, documenting systematic brittleness across models that “sounded right but reasoned wrong.” More critically, students built understanding of how to evaluate AI outputs. The midterm gave them agency as investigators rather than passive users. Eager to share their discoveries, they are co-authors of this article. Together, we offer here to educators and the broader scientific community a concrete…
