Mathematics Majors’ Diagram Usage When Writing Proofs in Calculus
Juan Pablo Mejía-Ramos and Keith Weber
We report on a study in which we observed 73 mathematics majors completing 7 proof construction tasks in calculus. We use these data to explore the frequency and effec-tiveness with which mathematics majors use diagrams when constructing proofs. At the end of the report, we discuss implications of our 3 key findings for pedagogy and future research.
