The relevance of this study is related to the fact that the necessity of compliance between the professional education system and progressive tendencies of world economy development demanded the formation of a new generation of economically socialized engineering and technical specialists, who own a sufficient level of economic competences, that will allow successful integration into the socio-economic environment. The purpose of the paper is to create the scientific basis of content, structure clarifying, creating and implementation the pedagogical conditions of students' economic socialization, considered as a process and the result of individual inclusion into the system of socio-economic relations in the society. The leading method of studying this problem is the project method, allowing to design a system of economic socialization of students on the basis of the relationship between the essential characteristics of the process of economic socialization, identified by socializing potential of the educational environment in technological university and transformative actions for realizing this potential to achieve the goals and objectives of the students' economic socialization. In the paper it is determined that the pedagogical activity on the designing of economic socialization system includes the following stages: the first (preliminary) stage involves planning of educational activities for the realization the target component of underway project (diagnosis, promotion of ideas, identification of goals and objectives of economic socialization, expected outcomes and the criteria for their evaluation), and, ultimately, development of the project. The second stage of the design is the project realization phase including the content, activity and technological components of the educational process. Third (reflective) stage includes analytical, corrective and remodeling aspects of pedagogical activity. The data from this paper have practical value in designing of economic socialization systems for future engineers, prove the causal dynamic nature of searching and the improvement of the educational process and offer opportunities to apply our approach to design educational systems in technological universities.
