Conferences 2006 - R. Brissiaud
## What is the initial representation of arithmetic problems before and after schooling?Speaker: Rémi Brissiaud (IUFM de Versailles) The question we address is the following: after schooling has taken place, does the initial representation of a problem most resemble a "situational model" (interpretation of the problem statement is followed by the selection of an operational procedure) or does it remain based on a mental simulation of the situation described in the problem statement (interpretation of the problem statement has itself an operational dimension)? We will show how it is possible to answer this question by re-examining the results of a longitudinal study of solving addition and multiplication problems by year 1 pupils (Brissiaud et Sander, 2005) and that these data reveal themselves to be clearly in favour of an initial representation that continues to be based on a mental simulation of the described situation. These results mark the importance of the isolated variable in this study: concordance/discordance between the initial representation of the problem and the efficiency of its numeric solution.
