One problem that afflicts teachers, particularly those who teach Differential and Integral Calculus, is the difficulty of students in mathematics content and the consequent lack of understanding of what is presented in this discipline. Numerous studies have been carried out with the aim of creating and improving new teaching-learning methodologies that make students active elements of the learning process. This work proposes the application of the Problem Based Learning methodology in the definite Integral topic of the Calculus discipline, in order to guide the teacher and contribute to the student having contact with the discipline in problems that represent situations closer to their reality. In this proposal the student will also make use of technologies that, although they are known, are often underutilized by them.
