In this article, we present an experiment carried out in an 11th grade class in the curricular subject of DG (descriptive geometry). In a context where failure is more in the national exam, as well as in the discipline's attendance, the main objectives that motivated the implementation of this educational experience, were, on the one hand, to increase the interests and motivations of students for learning DG and, on the other hand, to prepare them for the final national exam. The project consisted of the development of multimedia applications based on the concept of podcast/vodcast/screencast--the geomcast. These applications were created by the teacher and students (in small groups), whose objective was to enable students to review the discipline's curriculum contents in any place or at any time, from the Internet, iPods or mobile phones, whenever the memory needs to be refreshed, since these multimedia applications were always available in the class blog.
