1998. Laureate of the Rostov Region Governor's Grant for his significant contribution to the development of natural science education in the Rostov Region.
From 1991 to the present, he has taught a course in general physics at the department. He taught the course "Modern Concepts of Natural Science." Recently, he has developed and taught the following courses at the department: "Thermodynamics and Heat Transfer," "Special Sections of Physics. Mechanics," and "Quantum Mechanics." He has published over 30 methodological works on various sections of physics courses, thermodynamics, quantum mechanics, and concepts of modern natural science. For his success in using the SFedU Incampus information environment in the educational process, he was awarded the Incampus Master 2009 award. Recently, he has been working on the implementation of modern information technologies in the educational process, as well as testing and interactive methods for assessing student knowledge. He is the author of two educational programs (electronic textbooks). He developed and implemented three electronic courses in various areas of physics into the curriculum, and published several papers on the application of modern technologies in physics education. In recent years, he has published seven textbooks on various sections of the physics curriculum.
He participates in organizing of the SFedU Physics Olympiad and the "Engineer - Profession of the Future" Olympiad for schoolchildren.
Along with his work in the Physics Department from 1990 to 2007, and from 2014 to 2018, he taught at the Taganrog Municipal Comprehensive Lyceum. During this time, he has trained numerous winners of city, regional, and state physics olympiads, for which he has been repeatedly awarded prizes and certificates.
Since 2023, he has been teaching advanced training courses in physics for teachers in the region as part of the Scientific and Educational Center for MP at the ICTIS of Southern Federal University.
