Ensino de modelos atômicos: aplicação de uma sequência didática (SD) utilizando softwares e a plataforma PhET.

Abstract

This research presents the result of the realization of a didactic sequence (DS), applied to students of Technical Education integrated in chemistry – Campus Itumbiara. It aims to develop, evaluate and implement a didactic sequence with the subject "Atomic Models", a theme that is part of the content grid of the Chemistry discipline. The research work was carried out during emergency Remote Teaching, using software and simulators as didactic resources. For the application of the DS, we researched free software and simulators available on the internet, aiming at accessibility so that all students could have access to education and prioritizing participants from public schools. Videos, images, interactive slides available on the Canvas platform, and software and simulators from the PHET platform were used. As an evaluation method, an online quiz was proposed, through Kahoot - an application that allows interaction and evaluation between students in real time, in addition to generating a certain competitiveness among students. Quantitatively, a survey was carried out among teachers from the city of Itumbiara-GO, with questions about the subject, such as which methodologies were used in the classroom and what are the difficulties in teaching-learning students in the Remote Teaching modality. Qualitatively, the students' production was analyzed, with the construction of visual elements referring to the themes worked in the classroom. As a main result, we can observe that the class presented a satisfactory learning gain, guaranteeing the quality of teaching even remotely.
