Descripcion de la practica docente a traves de la interactividad profesor-alumnos

Starting from a constructivist conception of the teaching and the learning, this work presents teacher-students interactivity as theoretical and methodological options to describe the practice of the professor in the classroom. A system of analysis of the interactivity is suggested that considers: interactivity segments, percentage of turns in the discourse, interaction between teacher-pupils and students-students, behaviors of the professor and the students. The description the teacher-students interactivity is exemplified in a classroom of primary.
