Proposal for teaching matrices through an Arduino electronic circuit

We live in an age when several studies are demonstrating that the teaching of mathematics must be done creatively, involving the use of different technologies and making the student the protagonist of the teaching and learning process. This article presents an educational product described as a proposal for teaching matrix concepts with two different activities using an electronic circuit: the Arduino. This proposal was developed to be used with high school students, in the classroom and in an electronics or computer lab. The students of the second year of a professional course integrated with high school in the city of São Paulo participated in the activities of the academic year of 2016. For the research development, we used the qualitative research methodology, being bibliographic research, action research and the application of a semi-structured interview with the participants as methods. As a teaching methodology, we use research and mathematical experimentation in our proposal. The results indicate, mainly, that students consider the class with the Arduino resource more motivating, dynamic and participative, promoting interdisciplinarity with other contents and the association of school learning with everyday life, arousing curiosity and investigative sense in addition to other considerations. The main advantage of our teaching proposal is that it allows students to interact directly with an experiment during math classes.
