A specific feature of the organization of education during wartime is the creation of a modern educational environment for the harmonious development of students in conditions of war. The substantiation of ways of developing qualities, values and competences of primary school students is important for solving a number of contradictions between the quality training of students to be competitive in the process of building labour relations at age stages, and the insufficient level of their real preparation for productive activities. There is also a contradiction between a significant volume of promising information in the conditions of rapidly changing technologies and unadjusted educational environment to innovative changes in terms of its analysis and use. The aim of the study was to determine the impact of the Moodle platform on the academic performance of primary schoolers under martial law. The aim was achieved through the use of the following methods: questionnaire survey, testing, methods of statistical analysis. It was found that the introduction of the modernized curriculum in the Moodle platform had a positive effect on the academic performance of the students of the experimental group (EG) compared to the students who used the traditional platform. The crosswords, interactive assignments, as well as animated videos in case of correct completion of tests were also added to encourage students to complete additional assignments after the lesson. This also affected the positive result of the final stage of testing. A promising direction for further research may be the development of interactive tasks for primary schoolers to better assimilate the material they have learned.
