Résumé

Cet article est une analyse du sens structurel que des lycéens (âgés de 16 à 18 ans) expriment lors qu'ils travaillent sur des expressions algébriques simples et complexes et qu'ils doivent simplifier des fractions algébriques qui impliquent des égalités remarquables : carré de la somme, carré de la différence, différence des carrés, propriété distributive et facteur commun. Par l'intermédiaire d'une épreuve écrite conçue dans ce but, un grand nombre de niveaux de sens structurels est détecté. Tous ces niveaux révèlent les différents degrés de validité des connaissances en ce qui concerne les égalités remarquables de la part de ces étudiants. L'analyse réalisée permet ainsi d'avancer dans la compréhension de la construction du sens structurel en identifiant quelques-unes des aptitudes qui le composent et le rôle joué par ce dernier lors des travaux réalisés par les lycéens.
