At the origins of the system of extracurricular activities in technical universities in Russia. Extracurricular work with students of the Navigation School in 1701-1705.

The subject of the study is the initial stage of the history of the School of Mathematical and Navigation Sciences as one of the first Russian secular technical educational institutions. Attention is focused on those aspects of the formation of the School that had not previously been the subject of special research by historians. Based on the complex of documents of the Armory Chamber identified and introduced into scientific circulation, it is analyzed which disciplinary and offenses the first students of the school committed and why. Analyzing the specific court proceedings conducted in the Armory Chamber on the fact of these violations, the authors show how extracurricular and educational work with students was organized. The role of Leonty Magnitsky, an outstanding Russian scientist, mathematician, author of the first fundamental work on arithmetic, in organizing educational work with navigation students, is being clarified.   The research was carried out using traditional methods for historical research, special attention was paid to the identification and introduction into scientific circulation of clerical sources on the chosen topic. As the study showed, the students of the School of Mathematical and Navigation Sciences came from various estates and regions of the Russian state. Once in Moscow, many of them found themselves in a social environment that was not familiar to them, faced temptations that were difficult for them to resist. In this regard, the teachers of the School, and first of all Leonty Magnitsky, paid great attention to educational work among students. An active group of schoolchildren was formed, who, on the instructions of teachers, monitored the behavior of their comrades. For the revealed violations, the perpetrators were severely punished in public. Extracurricular work contributed to the formation of a unified system of values, instilling interest in learning, instilling discipline, and eliminating vices among students. It has become an important factor in achieving the main goal for which the School was established: to train navigation specialists necessary to create a navy in Russia in the shortest possible time.
