The aim of this paper is to present the development of a Computer Aided Pedagogical Engineering studio which provides assistance to any teacher wishing to develop educational devices. The devices, which interest us allow the learning of vocational skills. They have been designed thanks to the pedagogical design method called MAUI. The Information and Communication Technologies will instrument the devices built from the studio. They will be adapted to the educational needs of the teacher. This article presents the context and motivations that led to the development of this studio. It then describes the MAUI design method which helped to design the educational devices based on the MAETIC pedagogical method. It then presents the conceptual architecture of the workshop and the various modules that compose it.
