The progress of society and technology has conditioned the change, that is, the progress of the educational system. By adopting a new document, the Curriculum of the subject Nature and Society, changes are being introduced in the teaching of Nature and Society. According to the Curriculum, the teaching of Nature and Society is based on constructivism and the Research Approach is at the heart of all concepts. The research approach is integrated into all concepts of the subject Nature and Society and should be realized through learning the content of the subject Nature and Society. The theoretical part of this paper describes a new curriculum, explains the concept of constructivism and defines the concept of textbooks. The aim of this paper was to determine to what extent the constructivist, research approach in teaching is achieved through the textbooks of Nature and Society made according to the new curriculum, ie whether each topic in the textbook achieves a research approach. The analyzed textbooks of Nature and Society were approved by the Ministry of Science and Education (2019/2020 and 2020/2021). A total of 8 textbooks were analyzed, of which 4 were for the first and 4 for the second grade. The research part of the paper presents the results of research that show that textbooks are not in line with the curriculum because they do not achieve a research approach in all teaching topics. We conclude that the analyzed textbooks only partially achieve a constructivist approach in teaching.
