Résumé
The objective of this study was to explore students`strategies for solving average problems and to see how these strategies change over high school, college and university. Students in high school (with and without having received a lesson on the average), in college and in university were tested. The results show that achievement does not necessarily follow the years of study particularly in problems where conceptual understanding is needed. College and university students tend to use algebraic strategies and are better at finding an average of grouped data. Strategies preferred by high school students use the total of the data and bring more success in "reverse" problems.
