Portable Experiments for a Vacuum Classroom
Education; Teaching Physics; ISLE Learning Theory; Portable Experiment.
This study aims to create a portable experimental device and a didactic sequence as an educational product to teachers in order to provide lack of supplies in the schools, mainly public ones that have not laboratory to experimental practices related to the vacuum theme. Didactic sequence has its bases on the ISLE learning active theory that consists in to realize experiments by the scientists through investigative method. The teacher of Physics and author or this research applied the didactic sequence. This study aims to contribute to the teaching of this subject and its relation to some phenomena. The application of this research (experimental device and didactic sequence) occurred with students from 2nd 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 to each one. Students received, in the pre-test as well as in the post-test, some 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. Didactic product achieved the proposal of this research, with efficiency, showing that students had a significant and participative learning.
