The praxis article is devoted to the study of educational cartoon as an interactive method of teaching legal disciplines. The purpose of the article is to argue the usefulness of this methodology for the educational process (e.g., the development of critical thinking, increasing the activity of students when discussing educational tasks on the basis of cartoons, clarification of complex terms), to improve the image of the university (use of educational cartoons in universities during the week of the Faculty of Law), and explain how we assessed the effectiveness of this methodology through quantitative and qualitative methods. While it is a new approach in Russian Law schools, we draw attention to the universality of this methodology; as educational cartoons can be used in schools and across different university departments, and to the specificity of modeling of educational tasks in law, by providing specific examples of such educational tasks. We propose three variants of development of educational cartoons for the educational process at law faculties: (1) placing an order for special production of educational cartoons; (2) use of fragments of already existing cartoons; and (3) creation by the teacher of oral tasks on the motives of national fairy tales. The results of our research substantiate that the greatest effect of the proposed methodology can give only in the case of using for the preparation of educational cartoons national content, which is closest to the culture and mentality of students of a particular university.
