The practice of defining differs across academic and non-academic discursive genres. As a result, students often have trouble formulating, interpreting, and using definitions in mathematical proof and problem solving. This design-based research project evaluated the conjecture that under appropriate conditions students could be steered to leverage naturalistic discursive practices in generating mathematical definitions. Specifically, I examined for learning effects of a dyadic game-based activity requiring the resolution of ambiguity in reference.
