The connection between mathematics and physics from the aspect of reasoning based on proportions and errors in the conclusion
Numerous researchers emphasized the connection between mathematics and physics, as well as the pupil's lack of linking knowledge gained within these subjects. In this paper, examples of the connection between mathematics and physics will be examined by the scientific reasoning test and the initial test created for this research. In the research related to the initial knowledge and scientific research, 235 students of the first and second grade of gymnasiums in Novi Sad and Backa Palanka participated. The results of the research have shown that most of the students did not correctly answer questions related to reasoning based on proportions. The obtained result points to the pupil's misunderstanding of the notion of the smallest interval of an instrument, that is, the value of an instrumental error, which is the basis of the correct reading of the experimental results in the teaching of physics. From the point of view of physics, it is important for pupils to point out the mistakes they have made in concluding, in order to correct their claims and the exact information associated with existing ones in longterm memory.
