Mobile devices for the study of linear functions

Abstract

This article reports the implementation of a didactic situation aimed at High School students for the study of linear function from movement activities. The situation led to a discussion about the variables involved, their relationship, variation, and the construction of graphs from physical movement, for this multimedia tablets were used to record the movement scenes and the Tracker software to analyze them. The didactic situation strengthened the idea of functional relationship between two variables and the students recognized that the inclination of the line is associated with the intensity with which the variables change.
