Desenvolvimento de um conjunto educacional para aprendizagem nas áreas de ciência, tecnologia, engenharia e matemática

Abstract

The changes proposed by the National Common Curricular Base and by the reform of the High School allowed to integrate contents of Science, Technology, Engineering and Mathematics areas to the curriculum of the Brazilian students. To do so, it was chosen to apply the methodology of Project-Based Learning through the creation of a Educational Kit financially accessible regarding those existing in the market, whose main element is the Arduino microcontroller. It was defined as the target audience of this Paper the students who attend the Final Years of Elementary School, in order to assist them in choosing the elective areas and to stimulate their interest in these areas. As an example of application of the Educational Kit, and inspired by the IEEE Very Small Size category of the Latin American and Brazilian Robotics Competition, a project called “Carrinho-Robô” (Robot-Car) was created. Its development is based on three aspects: the Electronics, based on components that compose the Educational Kit; Design, made in AutoCAD and sent later for 3D printing; and the programming, elaborated through the platform Arduino IDE. Four programs have been created, in which the robot behaves differently: in Basic, it moves in a predefined sequence; with Color Sensor, it takes different decisions depending on the identified color; with Ultrasonic Sensor, it deflects from obstacles in front of it; and with Radiofrequency Sensor, it is possible to control your movements remotely. For all cases, satisfactory test results were obtained.
