Uso do software virtual chemistry lab como recurso auxiliar no processo de ensino e aprendizagem de química.

Abstract

In teaching Chemistry, technologies have been a differential and a facilitator for learning, because in addition to the lectures, students can work and see molecular structures, atoms, chemical reactions, among others. For a long time in teaching, teachers always used the picture and the brush as the only means of teaching their classes, so that the students were always dispersed. The Virtual Chemistry Lab brings a variety of virtual experiments, where approaches are used to familiarize learners with laboratory techniques and procedures used. In this way this work aims to analyze the contribution of Virtual Chemistry Lab Software in the process of teaching and learning of students. The methodology was developed in four stages, in which the first stage consisted of probing the knowledge of the students about the content of acids and bases through the Brainstorming method, the second step required the explanation of the content in more depth, the third stage it was necessary to divide two groups to work titration HCL with NaOH, in which one group worked with the software and another through the blackboard; and in the fourth stage a questionnaire was applied. Thus, the questionnaire had eight questions, with four questions on the content of acids and bases and four on Virtual Chemistry Lab software. The results showed that the students who used the software understood the content better, thus corroborating the effectiveness of the use of technologies as a facilitator in the teaching - learning process.
