Unpacking 9th grade students’ algebraic thinking

Abstract

International audienceThe purpose of the present study was to propose and empirically validate a model describing secondary school students’ algebraic thinking. Based on a synthesis of the literature, a model for Grade 9 students’ algebraic thinking was formulated. The major constructs incorporated in this model were “generalized arithmetic”, “transformational ability” and “meta-algebra”. The study involved one hundred fourteen students. Data analysis validated the hypothesized model and suggested a sequential effect between the three factors. Transformational ability had a direct effect on generalized arithmetic and the latter had a direct effect on meta-algebra
