Analysis of Students' Reasoning when Solving an Algebraic Generalisation Activity

The aim of this study is to analyse how Moroccan pupils in the sixth year of primary school (11-12 years old) and the first year of secondary school (12-13 years old) use their reasoning and symbols to solve a task based on figurative regularities. The proposed activity was structured and analysed according to Dörfler's model (1991), integrating reasoning processes based on this model. The results of this analysis were used to identify students' predispositions and potential for solving this type of task, as well as the different types of symbolisms used before and after their introduction to algebra.
