Modernization of the elementary school teacher training system in Ukraine is due to challenges at the internal and external levels. The essence of these challenges is to bring teachers closer to the socio-cultural needs of junior pupils’ education. External challenges are due to intercultural interaction in a globalized space. Therefore, the article deals with the preparation of a teacher for the dialogic teaching of pupils as a means of forming functional literacy. The solution of this problem is considered in the context of changes in the value priorities of education (from the subject-content – to the person-oriented), which makes it possible to build childhood-centric connections of the learning process. Therefore, the preparation of a teacher for dialogue teaching is focused on the improvement of pedagogical (didactic, methodical), psychological components of general and professional competence. Studying the research of a given topic made it possible to distinguish two groups of sources: 1) works that reveal the strategies of pedagogical education (V. Andrushchenko, N. Bibik, V. Bondar, O. Savchenko, S. Sysoeva); 2) works that highlight the peculiarities of the preparation of elementary school teacher for the organization of dialogue teaching (N. Mikhailova, S. Yusin, O. Alexander, O. Moroz); the philosophical aspects of this problem are disclosed in the writings of I. Zyazyun, V. Ognevyuk.
