Analysis of the underlying cognitive activity in the resolution of a task on derivability of the the absolute-value function: two theoretical perspectives
Abstract
This paper presents a study of networking of theories between the theory of registers of semiotic representation (TRSR) and the onto-semiotic approach of mathematical cognition and instruction (OSA). The results obtained show complementarities between these two theoretical perspectives, which might allow more detailed analysis of the students’ performance.
