Résumé
The objective of this study was to see how students’ strategies for solving weighted
average problems change over their high-school years. The questions were: What
knowledge of the weighted average do children have before the introduction to the
concept? What strategies they use to solve problems through their high-school years? Do
they improve after formal instruction? Do they differ across grade levels? Are errors
persistent?. A written test with significant situations which covered various contexts and
representations was given to high-school students (N= 598) prior to instruction on the
average (8th grade), at the moment of instruction (9th grade) and a year later (10th
grade). Analysis of the students’ papers looked for stable strategies, modifications from
one level to another, and the impact of the different variables put in place.
