Today in Ukraine there is an interest of representatives of different categories in national martial arts, namely: «Asharda», «Boiovyi hopak», «Kozatskyi dvobii», «Rukopash Hopak», «Rukopash Spas», «Fri-fait», «Кhortynh» (transliteration from Ukrainian) etc. Systematic training in the chosen type of martial arts mentioned above provides the formation of self-defense skills, as well as promotes physical and spiritual development of the individual. It should be noted that classes in national martial arts provide the formation of: national identity, patriotism, as well as the creation of a reliable reserve of defenders of Ukraine, which in today's reality is an important practical task. Taking into account the results of the analysis of scientific-methodical, special and reference literature it is established, that the issue of modernization of the system of physical culture of male and female students in the New Ukrainian school with an emphasis on the use of national martial arts is devoted to an insufficient number of scientific and methodological works, this in turn requires further research and emphasizes the relevance and practical component of the chosen direction of scientific research. The main purpose of the study is to develop a project of a variable module «Kozatskyi dvobii» – a component of the model curriculum «Physical Culture, 6th grade» for secondary schools of the New Ukrainian School. In the process of theoretical research, the following methods were used: axiomatic, idealizations, historical and logical, convergence from the concrete, formalization, etc. In addition, in the dynamics of research work, members of the research group used their own experience in organizing section work in: general secondary education institutions; higher education institutions and private sports clubs. As a result of research and analytical work, a project of a variable module «Kozatskyi dvobii» was developed – a component of the model curriculum «Physical Culture, 6th grade» for secondary schools of the New Ukrainian School. The variable module developed by us above provides: determination of expected results, proposals for the content of the subject, as well as types of educational activities of students. Prospects for further research in the chosen direction include the development of a project of a variable module «Asgard» (for girls, part of the model curriculum «Physical Education, 5-6 grade» for secondary education) of the New Ukrainian School.
