As both research and pedagogical practice show, one of the results of moral education is a developed interest of high school students in the ways of constructive communication and their striving for acclaiming these ways. In this process, constructive communication among students may be considered an important value. By the term constructive communication we understand such communication that allows to reach out for somebody and also to receive this person’s agreement with different partners and, particularly, to find ways out of different conflicts, which will satisfy all the parties involved. Our research (Pyotr G. Averianov, Elena L. Petrenko, Sergey D. Polyakov, Inna J. Shustova) tends to answer the question, how a teacher can stimulate this interest and develop necessary skills (Averianov et.al., 2010). We base our experimental work on the stages of psychical development presented in the works of a famous Russian psychologist Daniel Elkonin, and the theory of the developing educational activity by Vasily Davydov.
