Utilização de modelagem molecular como ferramenta auxiliadora do ensino de geometria molecular em uma escola de ensino médio de Paulistana - PI

Abstract

The use of Digital Information and Communication Technologies (DICTs) has become increasingly present in the school environment, serving as a supporting tool in the teaching and learning process. The present study had as its general objective to integrate the structure of traditional teaching with technological applications in order to improve the understanding of CETI Paulistana students regarding molecular geometry. The research was conducted in the city of Paulistana-PI, at the state school Centro Educacional de Tempo Integral (CETI) Paulistana, where the content of Molecular Geometry was approached using two different methodologies. In the 1st Year of High School – Technical Course in Administration, the content was taught through traditional instruction, with the topic explained using the whiteboard. In contrast, in the 1st Year of High School – Technical Course in Systems Development, the content was addressed with the support of the Avogadro software. It was observed that the class in which the content was taught with the use of DICTs demonstrated greater student engagement. Based on the results obtained from the applied questionnaires and classroom observations, it was evident that this group achieved more positive outcomes. Therefore, it can be suggested that the use of technology contributed to students’ learning by providing a less abstract visualization of molecules, in addition to significantly enhancing the learning process.
