Grafos: uma experiência no Ensino Médio

Abstract

Mathematics has been highlighted as the basis for most current science and technology. It is believed that current technologies (mobile, social networking, GPS, among other) are of interest to students of high school. Assuming that basic topics in Graph Theory require few prerequisites to be taught and that these topics are directly linked to current technologies, an experiment with graphs in high school fits perfectly on the goal of a survey focused on mathematics education. This work aims to describe a Graph teaching experience in high school classes of a Technical School in Cruzeiro / SP through an investigation study. The instruments used to collect data were six classes with fifty minutes each one. There were introduced concepts and basic results from Graphs. Two tests were also applied, one before and the other after the classes. The students could preliminarily experiment high school techniques; after the Graph classes, they could use what they learned. In the end of the work, after the classes, a questionnaire was also applied to diagnose the motivation and the interest of the students in Graphs.
