During the students' independent work, I went around the class and tried to help the students and explain their shortcomings. I was intrigued by the fact that many students managed to fill in the sheets quickly and independently. Then, on the other hand, there were students who did not have a basic knowledge of oxidation numbers at all, without whom it is difficult to proceed and they did not mind at all. They tried to have a phone under the bench and showed no interest in trying to explain the context.
