The article deals with the analysis of the problem of developing the dialogic culture of the future educators in terms of their professionalization. The author has shown that the congruent coverage of the specifics of forming an individual as an entity of professional activity in the continuum of the modern culture can be carried out only within the dialogic mode. It has been found that de-valuing the psychological component and accumulating systems of algorithmic tasks of the test type in the practice of the professional training makes it impossible to develop the communicative (and especially dialogic) culture of a specialist. The dialogic culture is interpreted by the author as an integrative construct of an individual, i.e. a set of communicative and technological indicators of the systemic behaviour (and professional-role one in particular) of the activity entity. The empirical research procedure had as its objective to outline the psychological tendencies in the development of the indicators for the communicative culture of the professionalization entities (bachelor degree and master degree students) in the modern educational space. The dominance of the monologic model of communication in the respondents' behavioural scenarios and the absence of the self-management development dynamics in communication have been statistically corroborated. The findings of the research are interpreted as the theoretical foundation of a modern model for the dialog-phenomenological interaction that is adequate to the new challenges of the time and the educational reform principles.
