Annotation: One of the key laboratory works in mechanics is the experimental determination of the coefficient of restitution of solids. A review of domestic and foreign sources suggests that information technology tools are often used to record the process of laboratory work, but the importance of processing experimental data using appropriate software is not noted. In the context of digitalization of engineering education, there is a need to use digital tools for statistical data analysis. This makes it possible to increase the accuracy and reliability of the results of laboratory work on the theory of impact. The authors of the article have developed a program for processing experimental data in Python. This software allows you to perform interactive data entry with verification of their correctness, mathematical calculation and output of results with verification of their reliability. The article suggests a methodology for conducting laboratory work on the theory of impact, which includes three stages: preparatory, experimental, statistical and interpretative. To identify an increase in the effectiveness of laboratory work, 197 students from the Berezniki branch of Perm National Research Polytechnic University were involved. Based on the developed criteria, the students were divided into three levels (low, medium, and high). Statistical data processing was performed using Pearson’s χ2-criterion. The approbation confirmed the effectiveness of the developed methodology for conducting laboratory work to determine the coefficient of restitution upon impact of solids. The article identifies promising areas in the development of methods for conducting laboratory work on the theory of impact. The methodology of laboratory work to determine the coefficient of restitution can be recommended to physics teachers of higher technical educational institutions.
