Résumé
This paper describes how eight undergraduate students majoring in economics and business studies reasoned about marginal change (marginal cost, marginal revenue , and marginal profit) in the process of deciding how they would advise the management team of an airline about an economic decision involving the addition of another jet plane. To elicit students' understanding of marginal change in an economic context, pairs of students were engaged in a task-based interview. Nearly all of the students were able to reason correctly about marginal change within the immediate context of the task, while four of the students also did so beyond the context presented in the task. Only one student considered the marginal change information in the task as a rate of change.
