摘要:Rapidly developing information technologies bring to crucial changes in different areas of student life activities - learning, communications, leisure – and have an impact on individuals’ activities. Empirical research aims to identify connections of activity and ontological security in communications, knowledge, learning, experiences, reflection. The assumption, that activity in communications and activity in learning have closer links with ontological security than activity in other areas of life, is put forward as a hypothesis. Theoretical basis of the research creates A.A. Volochkov’s concept of activity of an individual (subject), N.V. Kopteva’s theoretical construct of ontological security. The research involves 97 students of medical college at the age of 17-21. The empirical research applied the following methods: methods of “Diagnostics of activity of students” DAS-2 (A.Yu. Popov, A.A. Volochkov); questionary of ontological security (OS-PM); method of ontological security built up on the principle of semantic differential (OS-SD) (N.V. Kopteva). As a result of empirical research, it was stated that broad-spectrum activity of students is implemented and developed in connection with one of the basic grounds of human – ontological security. Out of three model components of activity structure: need in interaction - volitional regulation of interactions - satisfaction with interactions, the first two components are stronger connected with ontological security that the third component. Out of the life spheres where the activity is found, activity in communication and activity in learning have closer connections with ontological security that any other areas of life.
