Experimentos portáteis para aula sobre o vácuo

Abstract

This study aims to create a portable experimental device and a didactic sequence as an educational product to teachers to provide the lack of supplies in schools, mainly public ones with no laboratory to experimental practices related to the vacuum theme. The didactic sequence has its bases in the ISLE learning functional theory. The teacher of Physics and author of this research applied the didactic sequence. This study aims to contribute to teaching this subject and its relation to some phenomena. The application of this product (experimental device and didactic sequence) occurred with students from the 2 nd level of the Integral Time High School, in the Escola Estadual Augusto Xavier de Góis, in Muriú, located in the Ceará-Mirim, region of Rio Grande do Norte, in the Physics subject. This activity comprehends six classes, considering 50 minutes for each one. In the pre-test and post-test, students received information about instruments to use during classes, based on qualitative and quantitative experiments about vacuum, showing a technological application and, consequently, the importance of this knowledge to our lives. The didactic product achieved this research proposal with efficiency, showing that students had significant and participative learning.
