Conscious of the contributions of the new information and communication technologies to improve teaching and learning, the Moroccan Ministry of Education insisted, through the educational and training national charter, on their use. Given the fast evolution of these technologies, “the school” has to question the modes of transmission, acquisition and restoration of knowledge. This entails not only changes in the selection and linkage of the objectives as well as in the contents of learning, but also a reflection on the way of conceiving and implementing education teaching. The teacher in sciences is based first of all on the natural real, he can use documents, which substitute this reality and approach the learner through graphics, iconic representations and audiovisual means, and it is in this perspective that the software Géo-terrain is built.
