Procedures Used by Students Aged 13-14 in the Resolution of Tasks Involving the Flat-Figure Area

Abstract

This study aims to identify the implementation of different partial meanings of the area in students aged 13-14 when solving area tasks. Written procedures and justifications are analyzed in three tasks and the partial meanings of the area used are identified. Six student profiles are established, according to the concepts, procedures, properties, and representations used by the students. The results show a generalized tendency of students to associate area with the use of formulas, showing little variation in procedures for area measurement and little relationship between the partial meanings of area.
