in the present research, we will synthesize the main research results about the development of interactive computer environments for physics teaching and learning. We will see that few types of software propose environments that take into account the user's erroneous representations in order to make him become aware of his mistakes. The majority of these softwares present modelling activities that are restricted to the automatic collection of experimental data and their analysis under graphical form. As a consequence, we will present the design of computer environments for the learning of the phenomenona of absorption and diffusion of light which will take into account the user's initial representations. The design of these environments is divided in five steps:(1) diagnostic of the user’s initial representations;(2) confrontation of the user’s initial representations by the simulation;(3) reconstruction by the user of his representations following the completion by the user of the simulation;(4) reconstruction of the user’s representations following the presentation by the software of scientific information related to the case studied and (5) assessment of the current state of understanding of the user by the software.
