Contribuições do software avogrado para a aprendizagem na disciplina de Química na Escola Tiradentes de Santo Ângelo - RS

Abstract

The present work brings the results of a research and analysis of dates, which had as objective identify the main contributions of the software application Avogadro in chemistry subject on high school, in the School of the State Tiradentes from Santo Ângelo –RS with the students of the first years of high school. The avogadro software was used to develop the content of chemical bonds, molecular geometry, polarity of molecules and water solubility of inorganic substances. This software enables the creation and visualization of 3D molecules. Of the four classes of first year of high school, two worked with the Avogadro software in the computer lab developing the content on chemistry subject about interatomic bonds, intermolecular bonds and physical properties of chemical substances. In the other two classes the content was developed in the classroom using only the resources of the textbook, green frame and dialogic lecture. After, was applied test for all students in four classes. The analysis of the results obtained by students in the assessment allows to conclude that the use of Avogadro's program as a support tool for the development of content produces satisfactory results. The use of this software provided a better understanding of the interactions that occur between atoms to form a substance and the interactions that occur between molecules of a substance or of different substances. The construction of mental models enables the learner a better understanding of the ways that atoms and molecules of substances interact.
