Didactic issues of code transitions: Characteristics, dynamics and differential effects

Abstract

This article presents the study of a specific point in the communicational dimension of didactic interaction: codic transitions, point where interactants slide from one communication channel to another. Our work, part of descriptive and comprehensive research, is anchored in an anthropological and comparative approach in didactics. It articulates three temporal and analytical scales to trace the joint dynamics of these codic transitions in their relationship with the transmission / diffusion of knowledge. Our results reveal that the codic transitions are described around several characteristics whose production has a different impact on the didactic process and reveal how they constitute a tool of analysis.
