This book focuses on the importance of including the concept of Ideology as one of the pillars of the methodological practice of teaching and learning and in the process of schooling in Geography. In our analysis, we look at how the concept is or isn't understood by high school students at a state school in the municipality of Viçosa, MG. To do this, we used bibliographical research on the concept of ideology from the perspective of some authors such as Marx, Gramsci, Mészáros and Santos as our methodological approach. In addition to some case studies and authors who deal with the subject, we also presented the results of the questionnaire applied to the participants and analysed the textbook. This makes it possible to assess, in addition to the potential, how school geography has directed knowledge in the classroom, in the textbook, proposing alternatives to reduce the possible conceptual insufficiency and engendering a brief reflection on the role of the geography teacher from a critical, reflective and ideological perspective.
