Etude Du Savoir À Enseigner Cas De La Liaison Chimique

Abstract

The objective of this work is to identify the components of the knowledge to be taught relating to the concept of chemical bonding and its associated concepts in specialized reference books intended for the cycle of bachelor's and preparatory classes. The reference works analyzed were chosen in such a way that the publishing years covered a long period. Examination of these works revealed that there is a clear discrepancy in the content of instruction. The definitions of chemical bonding in reference books depend on the dates of publication of each book. In addition, the set of concepts associated with chemical bonding appears to have several definitions that are sometimes different in the background and may cause learning barriers.
