Réalisation d’un didacticiel sur la notion de réaction chimique en classe de troisième au Cameroun.

Abstract

The experimental sciences teaching in Cameroon and Chemistry in particular encounter enormous difficulties mainly cause by the lack of equipment and reagents in laboratories. In this work it is exposed some educational concepts in the general point of view, problems bound to the teaching of the chemistry in the context of Cameroon and pedagogic and software engineering use for the conception of DIREAC. For the conception of DIREAC we have used ADDIE model and cascading model. This memo is an interactive learning digital space offering learners the opportunity to understand chemical manipulations. DIREAC (Tutorial on chemical reactions) have been made to resolve all these problems and to permit the educational integration of ICT. This tool should permit to vary the methods of training and to solve the problem of the real laboratory insufficiency in Secondary schools of Cameroon. Thus they can boost their understanding and achieve satisfactory results.
