SOUSA, Emerson Silva de; VIALI, Lorí  e  RAMOS, Maurivan Güntzel. Construction and analysis of exponential models in a meaningful way: a teaching experience in the classroom. Rev. Exitus [online]. 2017, vol.7, n.2, pp.55-73.  Epub 15-Maio-2019. ISSN 2237-9460.  https://doi.org/10.24065/2237-9460.2017v7n2id302.

The purpose of this article is to describe an activity that was carried out by the construction and analysis of some mathematical models in the context of the study of exponential functions, using empirical data and using the use of computer tools. It seeks to identify in this process some elements of Significant Learning Theory. The activity was carried out within a PreCalculation course with students of several undergraduate courses of a public university in the State of Pará. After the activity was accomplished, the students demonstrated to have understood the concepts and properties related to the exponential functions, signaled a Interest in the subject, since they could identify its application in several areas of knowledge, as well as the opportunity to learn and work with some computer tools such as Excel and GeoGebra.
