The article is dedicated to the current problem for the present situation in the education of Ukraine. It is the issue of preparation of qualitatively new teacher of primary school whose specific feature of work is multidisciplinary. Unlike single-subject teachers, he must master methods of teaching the Ukrainian language and literature reading, mathematics, fine arts, music, technology, the world around us and other educational disciplines. All this requires closer attention to the practical training of a primary school teacher, the formation of his individual creative abilities, which would allow him to successfully carry out educational-and-upbringing activity with the students of primary school level of general secondary education in the future in modern educational establishments of various types. The authors make actual the antinomies that arise at different structural levels of the educational system, which, in turn, causes misunderstanding between the participants of the educational process, on the one hand, and the relevant management units – on the other hand. According to the authors, the subject paradigm must take into account not only the teacher’s offer, which must be mastered during the study of a discipline, but to ensure student orientation in the issue of «What will the study of the discipline give for my profession?». This orientation will show the gaps in the educational program, in particular the redundancy of educational disciplines that do not provide the formation of professional competencies. The authors at the classes of the following courses: «Modern Ukrainian Literary Language», «Methods of Teaching the Ukrainian Language in Primary School» conducted an experimental study for 5 years, which showed that the systematic use of methods and techniques for the development of critical thinking («Thick and thin questions», «Cinquain», «Cluster», «Zigzag», etc.) allowed students to master the theoretical material and perfectly implement it in practice and contributed to the development of professional competencies
