Desenvolvimento e análise de material didático on-line para o ensino de conteúdos de química orgânica: controle biorracional de insetos pragas

Abstract

This research has focused on exploring the possibilities and limitations of a WebQuest as an educational tool implemented to cover different topics of Organic Chemistry related to plague insects and their biological control in crop management, Controle Bioracional de Insetos Praga (CBIP), a research program linked to the National Institute of Science and Technology (INCT) at UFSCar. This case study dealt with the controversial socioscientific issue that represented the control of fall armyworm (Spodoptera frugiperda) which caused damage on local corn crops, and was performed by a high school class in the Junqueira Educational Center, located in Morro Agudo, SP. The relationships among science, technology and society (STS) and central dimensions to make decisions regarding the addressed problem, as well as the learning possibilities offered by the WebQuest could be understood in a broader context. In order to evaluate the student s performance, their whole textual production towards the resolution of the problem was considered (questionnaires, reports, power point presentations etc.), exposing the alternatives found for this particular plague control in corn crops (mechanical, biological and chemical methods), pretending for that matter to be a fictitious company responsable for the optimization of its corn production. It was possible to verify that the students previously divided into three groups managed this particular task successfully which required analytical and scientific judgement.
