The article analyzes the results of a pedagogical experiment aimed at increasing the level of formation of a scientific worldview among foreign cadets. During its implementation, experimental and control groups of cadets were created, similar in their qualitative characteristics. To determine the initial level of formation of a scientific worldview, the evaluation methods “Scientific concept of the world” and “David Wexler Intelligence Test” were used. The research results were analyzed using methods of mathematical statistics, in particular, the Mann—Whitney U-test, which allows us to assess the degree of difference in the results of testing of individual groups. Then a methodology was proposed for the experimental group — a special course “Formation of a scientific method of cognition among foreign servicemen in military universities of the Russian Federation”, and in the control group — a traditional methodology. At the end of the pedagogical experiment, the collection and comparative analysis of data in both groups of foreign cadets was repeated. The study showed that after the behavior of the experiment, the test results of the experimental and control groups have significant differences, which indicates that there is a positive effect of the method under study.
