المركبات التكافؤية من نموذج لويس إلى النموذج الكوانتي: دراسة تقويمية لصعوبات التحصيل المفاهيمي عند طلبة المدرسة العليا للأساتذة بالقبة، الجزائر

الملخص EN

This work aims to evaluate students' difficulties in acquiring knowledge related to Lewis and quantum models used to describe the structure of organic compounds.

we analyzed the extent to which students-professors of physical sciences could establish relationship between concepts related to each model by describing simple, double and triple bonds in proven sentences.

the lack of control over this knowledge may constitute an obstacle to explain the effectiveness of organic compounds.

based on a questionnaire, we found that the knowledge gained by the majority of students remains incomplete and cannot be described as expository knowledge with theoretical knowledge.

they only got a “procedural” knowledge for the various models of equivalence bonding.

based on thinking logic used by students, we revealed a number of alternative conceptions.
