The purpose of this work is to analyze domestic and foreign theoretical material and practical experience of using an interdisciplinary approach in teaching foreign languages in a non-linguistic University, in order to identify the most effective approach or model. Results: after studying and analyzing the existing theoretical and practical experience of teaching foreign languages, the authors came to the conclusion that the method of content-language integrated learning is the most effective within the framework of an interdisciplinary approach, since it allows integrating the content of a professional discipline and a foreign language in the learning process. The article defines the method of content-language integrated learning, considers the models of using this method, and provides examples of practical use of this method in teaching students of a non-linguistic University. With this approach, a foreign language becomes a means of learning from the goal of learning, which leads to an increase in students ' motivation. Conclusion: the article analyzes the advantages of using this method, as well as notes the objective difficulties and possible problems.
