The rules for the order of operations: The case of an inservice teacher

Résumé

In this paper a two-stage project is presented concerning the rules for the order of operations. During the first stage the mal-rules used by an experienced teacher as he evaluated arithmetical expressions were recorded and a session for repairing these misinterpretations followed. During the second stage the influence of the teacher's teaching on his sixth graders was examined. The findings showed that the initial understanding of the teacher was so persistent that almost all his students and in order to evaluate the same arithmetical expressions used exactly the same mal-rules.
