The study aims to understand and identify the strategies used by Pedagogy students to solve a Mathematical Modelling problem situation that may involve proportional reasoning. For this, a case study was developed with a group of 32 academics from the fifth semester of Pedagogy from a public institution. Data came from a Mathematical Modeling practice developed in the classroom, in a dedicated time to study trends and were obtained from the material prepared by the 13 participating groups. The analysis showed that academics in the face of a Mathematical Modeling problem situation make use of different strategies for solving, in which a multiplicative scalar factor and a functional factor are evidenced. Among the strategies, those with errors were not identified and, in all of them, there are possibilities for them to be applied in the initial years. It was concluded that in 11 groups the strategies show the use of advanced and pre-formal proportional thinking.
