In arithmetic problems solving, the representation of the problem spontaneously induced by the content of the statement is not always compatible with the solving strategy. This study evaluates a learning approach designed to lead pupils to build an alternative representation to the one spontaneously induced. In this paper, we evaluate the efficiency of this learning approach with children with learning difficulties enrolled in a priority education network. This learning by semantic recoding is a process based on an analogy between the problems and a comparison of strategies. The results show that after learning, the pupils built alternative representations. [less ▲]

En résolution de problèmes, différentes études ont montré que le contenu d’un énoncé ne fait pas qu’habiller une certaine structure mathématique mais que des processus interprétatifs interviennent à partir de ce contenu et participent à la construction de la représentation de la structure du problème. La première partie de cet article propose une synthèse des travaux montrant que le contenu de l’énoncé influence la mise en oeuvre de la stratégie de résolution et la performance. La seconde partie présente une démarche d’apprentissage qui vise à rendre l’apprenant moins dépendant du contenu de l’énoncé en le conduisant à remettre en cause la représentation spontanée du problème. L’apprenant est ainsi amené d’une part, à développer sa capacité à changer de point de vue, c’est-à-dire, à développer une flexibilité cognitive plus grande et d’autre part à traiter les problèmes de plus en plus abstraitement. Cette démarche d’apprentissage a été menée auprès d’élèves de Grade 4 (9/10 ans) et de Grade 5 (10/11 ans) de l’école primaire scolarisés en classes ordinaires (Gamo, Sander et Richard, 2010) et en réseau d’éducation prioritaire (Gamo, Nogry et Sander, 2014). Les résultats des recherches pour évaluer l’efficacité de cette démarche sont présentés. Les implications de ces résultats pour les apprentissages scolaires sont discutées. [less ▲]

The underlying assumption was that the nature of the variable involved in an arithmetical problem in which there are several solving strategies influences the construction of the representation and might force the strategy used, hiding the possibilities to become aware of others (Gamo, Taabane & sander, 2011). This study intended to lead pupils to build an alternative representation than those spontaneously induced by the statement. It investigated the role of training of semantic recoding based on an analogy between the problems and a comparison of strategies to facilitate transfer of problem-solving strategies in problems sharing the same formal mathematical structure but differing in semantic representation [less ▲]

The assumption underlying the present study is that the nature of the variable involved in an arithmetical problem in which there are several solving strategies influences the construction of the representation and might force the strategy used hiding the possibilities to become aware of others and influence the performance. An experiment was carried out among 4th and 5th grade pupils who had to solve isomorphic problems in which two solving strategies can be admitted withWeight, Height and Duration variables. The results showed that the spontaneous implementation of these strategies and the performance depended on the nature of the variable involved in the problem. Implications of these results for educational purposes are discussed. [less ▲]

Transfer of strategies between problems sharing the same formal structure is facilitated by a semantic recoding that makes evident the structural similarities between the problems. Two experiments were carried out among 4th and 5th grade pupils, with an experimental group trained to compare strategies in order to reinterpret an arithmetic word problem so that the calculations are consistent with the interpretation, and a control group. The experimental group in Experiment 1 improved significantly by choosing the alternative strategy in problems different from those used in training but no significant progress was observed in the control group. Experiment 2 showed that the improvement observed in the experimental group could not be attributed to the fact that children only learned to use a superficial rule. These results support the idea that the activity of problem re-representation may be a crucial step in mathematization. [less ▲]
