Abstract

This work to conclude the Mathematics Degree course offered by the Federal University of Ceará aims to bring a study on the teaching of straight lines at the 4th College of the Military Police of Ceará Minister Jarbas Passarinho and collect data on the effectiveness of the applied methodology. In this sense, a class project was created that presents properties and scenarios involving the straight line. To this end, the theoretical content with involved properties was presented, using a dialogical expository class plan, with the aim of bringing greater student participation and streamlining teaching during the class. Therefore, the research was developed using a quantitative, descriptive and qualitative model, characterized by involving the investigation of data collected from a studied population. From this, the action research model was chosen to carry out the work, which involves both members of the environment studied and the author in the situation. Subsequently, a questionnaire was administered to obtain the students' level of understanding. The quantitative analysis was carried out by observing the results collected by the observer. This evaluation proved to be a positive indicator given the strategies and devices used to present the planned content.
