Actividad conjunta y habla: una aproximación al estudio de los mecanismos de influencia educativa

This paper presents the theoretical and methodological options of a research project whose main objective is the study of some mechanisms of educational influence. The stress is placed on the mechanisms involved in teacher/pupil's group interaction and adult/child interaction. Taking the concept of interactivity—the forms of organization of the participants joint activity on content or task—as a starting point, two mechanisms of educational influence are analyzed: the progressive transfer of responsibility and control and the progressive construction of shared meanings.
