Uma proposta de sequência didática utilizando aulas experimentais para o estudo de mecânica

Abstract

This work proposes the use of didactic sequences as an alternative pedagogical approach for teaching experimental Physics, aiming to spark students' interest in science and foster new teaching strategies for basic education teachers in schools without experimental laboratories. The proposal is structured in two stages. The first involves constructing an experimental apparatus consisting of an air track, made using 3D printing and low-cost materials, combined with an Arduino board connected to optical sensors for data acquisition and experiment control. The second stage consists of applying the didactic sequence, divided into two phases. In the first phase, theoretical content and the technique for constructing concept maps will be introduced. Subsequently, in follow-up lessons, students will be guided to create concept maps using only theoretical concepts. In the second phase, students will conduct an experiment alongside the teacher on the same topics and later develop a new concept map based on the practical experience. It is expected that the use of the experimental prototype, combined with didactic sequences, will help make Physics teaching more dynamic and meaningful, stimulating students' curiosity and promoting a more concrete and significant learning experience.
