Few evaluated classroom exercises to date have addressed one of the most cited and compelling explanations of gender formation over the life course: interactionist gender theory. This theory posits that people actively "do" or "perform" their gender in every interaction, and as such, they often subconsciously reshape their public gendered personas based on the degree to which they find social acceptance within a given social context. This paper presents a highly engaging and temporally compact classroom exercise utilizing simulated speed dating to illustrate and generate discussion about interactionist gender theory among undergraduate social sciences and gender studies students. An evaluation study indicates that the exercise improves students' perceived understanding of interactionist gender theory and that it is both highly helpful and enjoyable.
