Chemical Thermodynamic Concept Mastering by Chemistry Students

The ruling objective of our research is to assess the grasp by students (Option: SMC) of certain chemical thermodynamic concepts that are being learnt in S2 as well as ensure the interpretation of certain organic chemistry phenomena. Our aim is also related to highlighting conceptual difficulties encountered by students. For this end, we conducted an evaluation test for the students of Ben M'sik Science Faculty option: SMC (S4, S6, Master and Doctorate). This test consists of seven questions that we have selected in such a way as to secure objectivity, non-redundant and providing a feedback as to the degree of mastering chemical thermodynamic concepts by students. In order to expand our database revealing the students conception of the thermodynamic chemistry concepts, we considered examining the answers to a question related to the first test (Option: SMC, level S2). So, we examined 956 exam papers. This number represents the total number of examinees. The result showed a flaw in the grasp of certain basic concepts of thermodynamic chemistry studied in S2. This problem was noticed at a variety of levels of studies (S2, S4, S6, Master's degree, Doctorate). Therefore, students move from one level to another carrying with them weaknesses which hinder their future learning.
