  • The system approach to educational work in the University

    Educational institutions of Russia, including the universities, the task of improving the efficiency of educational work. In this regard, an interesting experience, Rostov state construction University (RSSU) as the University in General and the Department of construction management (OS), in particular. RSSU from 2014 introduced the obligation of all teachers to report specific educational work along with the statement of methodical and scientific works. Depending on the type of educational event is assigned a certain number of hours. The Department OS is a comprehensive educational work, which includes not only leisure activities, but also to involve students in scientific and methodical work. A systematic approach to the education of students involves performing teachers lectures on the history of the country in General, the history of construction and architecture; the participation of students in the preparation of guidelines, research, culminating in the writing of scientific articles and / or registration of a patent for an invention (utility model) or computer programs. Analysis of the annual experience of educational work under the new scheme, led to the conclusion that the best curators, as a rule, are teachers whose scope of training load significantly above average – 1,3-1,5 bets, or pensioners. The analysis of the educational work of the Department OS also launched another criterion for evaluating the work of the curator, if he works at the Department. This is the number of students who are registered to perform the final work to the Department, a representative of which is the curator. A systematic approach to educational work allows even at the beginning of training to select students wishing to do research, to identify young talents and to improve academic achievement in the educational process.
