Uma proposta de ambiente virtual para promover a aprendizagem significativa de transformações químicas

Abstract

High school students may have difficulty with basic concepts of chemistry. For lack of contextualization of concepts such as physical and chemical transformations, which are present in everyday life, cannot be perceived and understood by students so that they fail to form subsumes appropriate for understanding more specific concepts of chemistry, as already confirmed by other studies. Used in this study information technology and communication combined with the meaningful learning theory order to provide the meaningful learning of concepts related to the theme of "chemical change" for high school students. We developed a qualitative research design and evaluation of a hypermedia learning material produced with the aim of providing students with a potentially significant support for the learning of chemical transformations. The material was tested and adapted during the research until the final version used. After analyzing the data collected, which included tests on comprehension of concepts and usability, we conclude that the material was significant for this group but that the development of materials with these characteristics should take into account the peculiarities of the students intended.
