This paper introduces a study, part of a work concerning a tool that enables teachers to create educational materials. Production of such educational materials is based on predefined templates that facilitate the teacher's creation process. In this framework templates are built on 3D space which is composed of different areas where a teacher can insert different types of medium elements (images, texts, videos, audios, 2D or 3D elements). The main area faces the user; the others form a semi-circle around the main area. Three types of buttons are located around the main area and some of them depend on the inserted medium. In our proposed space, the learner is immersed in a space where: a) he is actor because he can act on various media contained in the education material; b) he can study one medium while perceiving the others; c) he is guided by animations that provide him feedbacks from the actions he has made.
