The present study revealed to us that there is an absence of practical work in physics in the laboratory in the 4th grade classes. To do this work, we prepared and distributed the questionnaires to students and teachers, distributed as follows:
- In high school-college A with 2 classes, we have 72 students;
- In high school-college B with 4 classes, we have 238 students;
- In high school-college C with 4 classes, we have 428 students;
- In high school-college D with 3 classes, we have 92 students.
After counting, we have.
- Out of 16 copies of questionnaires given to physical science teachers working in 4th grade in public and private establishments, 10 were recovered, or 62.5%.
- On the students' side, the 30 questionnaires and one hundred (100) copies of the series of exercises were fully returned, i.e. 100%.
Our work shows that 4 out of 10 teachers teach 80 to 100 students/class and 6 out of 10 teachers teach between 100 and more/4th grade class. It emerges that (60%) are responsible for "overcrowded" classes (100 and more than 120 students) and 40% intervene in classes with overcrowded numbers (80 to 100 students/class).
In the same sense, this form of practice in classes, lecture-based teaching leads students to simple temporary memorization, making it difficult to understand, assimilate and reproduce appropriate scientific concepts. On the one hand, teachers are overwhelmed with a number of classes and levels without the basic documents and adequate experimental equipment
