ABSTRACT
This chapter describes the methodological principles of design-based research (DBR) identified in recent studies on digital education and shows how these principles serve as a structuring basis for describing the DBR project conducted by our multimodal media literacy (MML) research team, titled “Co-creation of MML activities in a digital context”. The contribution of this chapter is essentially methodological (first section), and the DBR described serves as a partial illustration (second section) – based on the principles and dimensions identified (pragmatic, collaborative, exploratory, and iterative) – to better explain the theorization process through the study of actual practices in the new digital teaching and learning environments. In the DBR example selected, the data obtained from collaborative research (process), ethnographic research (profile), and developmental research (project and production) were used to gain a better understanding of the manifestations of young peoples’ digital MML skills in their practices at school and in informal settings, and of the types of educational activities that encourage the use of these skills.
