Utilização de aplicativos móveis para melhor compreensão dos assuntos de geometria molecular, polaridade e forças intermoleculares, no contexto de aprendizagem significativa.

Abstract

Digital Information and Communication Technologies (DICTs) appear as a way of demystifying Chemistry that is considered by the students of High School, one of the contents most difficult to be understood. This problematic may be related to the fact that some contents is subject to the analysis of microscopic data, making difficult the understanding of certain phenomena and visualization of the molecules. Considering that, a search for new educational software (mobile learning) that focus on teaching of chemistry, has been growing in the present day. These applicative in conjunction with the active methodologies assists in the understanding of the how to behave a certain geometry in the space, making a class become more interesting and attractive for the student. Moreover, the ability to understand a primordial part of chemistry which molecular geometry, since from this subject one can include others such as: dipole moment and intermolecular forces. The research aimed to develop a study related to technology and classroom allows students to learn through the use of mobile applications, the themes of molecular geometry, dipole moment and intermolecular force having as methodological proposal active learning and mobile leaning. The school that applied this research was Escola de Ensino Médio Governador Adauto Bezerra focusing on 3rd students of High School. Initially, an initial questionnaire applied and an interview with the students, after that was given a totally expositive class on the themes, and finally, the last meet with students, was used the applications and then was applied the final questionnaire. From the data collected in the interview and results obtained from the questionnaires, it was verified that the students had a more effective learning, using the mobile phone and the methodologies addressed of the content molecular geometry as well as presented an evolution in the definition of the concepts of dipole moment and intermolecular forces.
