"Nylon-forte como o aço, delicado como uma teia" - uma WebQuest para o ensino de polímeros em uma abordagem CTS

Abstract

Today, it is increasingly common to use the internet in the support of teaching and learning activities, allowing the school searches can be made exclusively from sources available on the Web, however, even with the easy access to information, there is the problem of the reliability and adequacy of them. Transform this information into knowledge requires strategies that make it possible to explore the internet for teaching and learning productively. This study aims to contribute to the teaching of chemistry with emphasis CTS, using the internet as an information source for knowledge building, seeking the formation of citizenship and social responsibility related to environmental issues involving polymers. Was developed for a class of third year of high school in a public school, organized in the format of a Webquest the analytical type, in the task of preparing a dissertation on polymers. The analysis of dissertations, using the technique of "Textual Discourse Analysis ", indicated that students expressed concern on environmental issues related to the use of polymers and were able to propose solutions to this problem, showing the effectiveness of the proposed approach with CTS exploiting data Featured on the internet. Thus, it was possible to explore scientific, technological and social aspects related to the polymers using the attributes of a Webquest.
