Abstract

Rational numbers are worked in Basic Education, however it is questioned what place they occupy within undergraduate courses and what approach is given when this subject is taught to future mathematics teachers. In the context, this work aims to investigate how the principles of the Three Worlds of Mathematics theory, advocated by David Tall, can support a proposal for the formation of future graduates in mathematics on concepts related to rational numbers and understand what results the proposal produces on these concepts learning. The researched subjects were eight students of a Mathematics Degree Course. This research is qualitative, being organized based on a teaching sequence substantiated on the chosen theory. In addition to assisting in the construction of tasks, this theoretical framework was also used in data analysis, which was collected through the students' productions. With the results, it was noticed that most students had characteristics of the Symbolic World in their productions, with some evidence of the Formal World, showing then the importance of the axiomatic construction of rational numbers in the training of students.
