Environmental education is a priority objective for the 21st century at all levels and modalities of the educational system and is a central concern of local and international organizations. However, there is still discussion about the most effective methods to achieve this goal, especially in higher education. The text presents the results of the implementation of the Case Study Method as a didactic strategy for the inclusion of the environmental approach in the training of civil engineers, obtained through a research carried out among five faculties of the National Technological University of Argentina. It offers reflections and suggestions for teachers who wish to apply the methodology, as well as concrete examples for its development in the classroom, adapted to different subjects and career levels.
