摘要：Founded on the proposition of the concepts of inclusiveness (capacity to include multiple stimuli) and penetrativeness (capacity of acting as a modifying vector) as basic characteristics of media; and on some perspectives about their languages; the author develops a reflexion about some attempts of using media and languages for educational purposes (learning and learning systems) observing the differentiated problems which present themselves to the organization of teaching in mediated and non-mediated situations. The author arrives then to the question of interactivity. After discussion on the "traditional" attempts of interactivity (in the 70's) and on recent naïve and mechanical attempts, he comments some interaction forms largerly worked by users of communication products. He finally emphasizes the interest in widening the knowledge over those interactions and in applying it to the work of educational communication.
