Recently, we have observed a significant increase in the recognition of geographical thinking as crucial for the training and performance of Geography teachers. This research aims to analyze how undergraduate students in Geography mobilize knowledge acquired in their training to develop lessons based on geographical thinking during their teaching internship at the Colégio de Aplicação da UFRJ. The structure of the thesis comprises six chapters. In the first chapter, we address the fundamental objectives of geography as a school subject. The answer to this question passes through the understanding of what we define as Geographical Thinking, supported by various sources and references. In the second chapter, we discuss the theoretical contributions of two authors from the field of education. In Lee Shulman, we seek to identify the different knowledge mobilized by teaching practice, understanding it as an intellectual work that involves a broad process of pedagogical reasoning. In turn, Basil Bernstein provides us with an understanding of the pedagogical recontextualization process, in which teachers transform the knowledge to be taught based on different principles and codes. The third chapter presents the various methodological aspects that guided the research. It is a case study with an inductive method and qualitative approach. As methodological procedures, observations of orientation meetings, interviews about the relationship between the formative trajectories and the process of developing teaching lessons, and documentary analysis of didactic materials produced by the undergraduates were carried out. The fourth chapter focuses on the formative trajectories of the undergraduates. The fifth chapter analyzes the process of elaborating the teaching lessons by the undergraduates within the context of the Supervised Internship. Data on the factors that influenced the choice of themes for the teaching lessons, the relationship with different aspects of individual formative trajectories, the impact and knowledge mobilized in the orientation meetings, as well as research, consultation, and study initiatives in the development of the work are examined. Finally, the sixth chapter focuses on identifying and analyzing the geographical elements present in the teaching lessons developed by the undergraduates. The research provides subsidies for thinking about the integration of essential knowledge for future teachers to highlight the relevance of the geographic discipline in the complex school context.
