Résumé
A study was conducted with 26 college students with the purpose of gaining insight into students' conceptual understanding of parameters in algebra. Participants contributed to a whole-class discussion, solved problems with parameters, and identified the parameters in each problem. About one third of the students had difficulty identifying parameters. Even when successful at identifying parameters, students had great difficulty solving the problems with parameters. The difficulty was even greater when the mathematical object was a family of quadratic equations. This suggests that the true difficulty lies not with identifying parameters, but with parameters in action, that is to say when solving problems with parameters.
