The article considers an idea of activity approach realization in professional training assuming not only change of the contents, forms and methods of students’ educational activities, but also not less radical transformation of teacher’s activities oriented at the students’ development of creative self-realization experience. The authors represent this approach in the context of new scientific field–pedagogical synergetics, which they understand as an open system of interaction of subjects of the educational process with each other and with environment. This system, being a subject-oriented one, is aimed at the nonlinear development of a creative subsystem of a personality, having the qualities of synergetic systems, what opens the new opportunities of self-development for it. The elaboration of experience of the creative self-realization of a personality, the emotional and valuable attitude to the activities becomes of particular importance. The conceptual and methodological novelty of the idea is caused by the abilities of various systems to the self-development not only due to the inflow of energy, information, substance from the outside, but also due to the use of their internal opportunities. The authors, focusing on understanding of pedagogical synergetics as a field of psycho-pedagogical knowledge, reveal the structural and functional model of creative development of a personality as a system of integrity. Thus it is shown, that not a personality sets the activities and not the activities set a personality, but a subject of activities, overcoming the contradictions of external and internal determination, makes the creative potential actual. The creative development of a personality is provided with synergetic interaction of such objective principles as: the purposeful educational activities, including the set of acme-synergetically-oriented disciplines, the practical importance of which consists in self-knowledge, self-organization. The feature of synergetic systems, important for professional and teaching activities, is that they can be controlled from the outside, changing the operating systems of factors. Integrity, hierarchy and professional and pedagogical orientation of expansion of the acme-synergetic contents of professional training of a future teacher confirmed a necessity of transition from management to self-management, from development under the influence of external factors to self-development under the influence of internal factors.
