This article deals with the performance of pupils of the 5th and 6th Biochemistry in the learning on the preparation of titrated solutions in analytical chemistry by the Investigative Approach.
The implementation of this approach was the subject of a study in the framework of our doctoral thesis in didactics of chemistry, motivated by the lack of conceptual, practical and epistemological learning caused by the classical method of teaching -learning.
The study aimed to propose learning activities to arouse interest of pupils in learning analytical chemistry and to incite them to carry out best performances.
In the end, the thesis has shown that the investigative approach is one of the appropriate methods to improve the performance of the students concerned in the above-mentioned learning.
The survey conducted as part of our thesis work in chemistry didactics showed that during the implementation of the investigative approach in the preparation of titrated solutions in analytical chemistry, the scientific documentary resources at disposal of 6th biochemistry students don’t influence their interest to learn chemistry and don’t improve the understanding of subjects taught.
However, the availability of a laboratory at school has a positive impact on the trainings.
The survey also showed that the influence on learning varies according to factors such as gender and education network of 6th biochemistry students.
Our wish is that the investigative approach as a teaching –learning approach be implemented and in classes of 3rd all sections of secondary schools in order to objectively grasp the students’ interest in learning.
