We report on results from 20 one-hour task-based interviews with 10 students enrolled in firstterm calculus. Each student participated in two interviews. The first interview included tasks designed to assess students’ ways of reasoning about fractions in static measurement scenarios (which did not involve varying quantities) and the second interview included tasks designed to assess students’ reasoning about scenarios involving quantities that co-vary. We discuss relationships between the ways students coordinated units in static situations and the ways students reasoned about co-varying quantities. The results contribute to the field’s understanding of the development of covariational reasoning and the role of constructing threelevels- of-units coordinating structures. [ABSTRACT FROM AUTHOR] |
