For this, the educational software JAVI (J’apprends AVec l’Informatique) will be used, and an elaboration will be done, in the form of an algorithmic structure, on a didactic profile by Competence Approach which will consist of specified tasks to be carried out by the user. The aim here is to create a useable tool which will be coherent in its Human-Machine interactions (HMI) between the user who is the educationist (pedagogue) and the computer scientist’s requirements - the program developer, hence matching the algorithmic sequence to the execution of related tasks. This action will enable the creation a system based on APCs, which could be used as a model for the creation of multidisciplinary educational software in Cameroon.
