UMA PROPOSTA DE ABORDAGEM NO ENSINO DE CÁLCULO ESTEQUIOMÉTRICO PARA O ENSINO DE QUÍMICA BÁSICA

Abstract

The present work investigated the study of stoichiometric calculus, in the scope of the new information and communication technologies in Chemistry teaching that was developed in a 2nd grade high school class, a private school college located in the city of The aim of this study was to study the stoichiometric calculation using mathematical concepts and a software of the color platform, on the balancing of chemical equations, as a tool in the teaching / learning process of chemical calculations. Guidelines on software, such as PhET (Physics Education Technology) Project, developed by the University of Colorado in the United States, were presented in the teaching of chemistry

in the classroom, in order to apply stoichiometric calculation concepts to common day- to-day life. Applied this tool with the students, we verified the validity of the

application of this approach in the teaching / learning process of balancing chemical equations, through two questionnaires before and after the classes in the laboratory, with positive results in the research. In this way, some students realized the efficacy and importance of these new technologies and mathematical concepts in the stoichiometric calculation approach in Chemistry classes.
