This article entails verifying the analogy of the user’s activity in the execution of various tasks – case of an CEHL (Computing Environment for Human Learning). 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.
