Módulos didáticos sobre tópicos de educação ambiental para o ensino médio

Abstract

This work is a proposal for the insertion of Environmental Education themes related to the use of chlorofluorocarbons and the ozone layer destruction, greenhouse effect/global warming, acid rain and water: pollution and treatment as a reference for Chemistry teachers working in high school. In order to do so, didactic modules were developed and adapted to the school curricula and also to the recommendations suggested by the National Curricular Parameters, adopting necessary requirements for an improved understanding of the environmental thematic. Thus, the development of such didactic modules is based on the significant learning by Ausubel, in which the information must interact and be based on relevant concepts already existent in the cognitive structure of the learner. By doing this, the material contributes for the presentation of theoretical concepts, experiments (whenever possible), and analogies about the effects caused by the environmental problem, describing what is being done to minimize the impacts observed on the environment and on the society. The didactic modules were provided for a public of 14 Chemistry teachers working in the high school level of federal, state and private schools of Santa Maria and Porto Alegre, in Rio Grande do Sul. The material has its structure organized in the development of the environmental thematic and contains four virtual modules which bring mainly explicatory texts, as well as illustrations and photos. The research was carried out based on data from questionnaires answered by the teachers who analyzed the modules. This work is characterized as an applied research with basic theoretical reference. Its approach is quantitative based on the Content Analysis by BARDIN (2011). The results of this analysis were considered favorable to the usage of the modules as a reference for teachers and students as an opportunity for the insertion of environmental thematic.
