Modelo científico explicativo da molécula do benzeno material didático estruturado na história da ciência

Abstract

We analyzed the Textbook Chemistry Program National Textbook for High School of 2008 (PNLEM/2008) and 2012 (PNLD/2012), with content analysis methodology, identifying problems in the approaches on benzene to subsidize developing a complementary teaching material. Prepared, applied and evaluated a Courseware, to supplement the textbooks based on the History of Science that presents a historical content on the Explanatory Models for Benzene Molecule (EMBM) in the order to support teachers and students in discussions about the Nature of Science (NdC) for the scientific work in the construction of these models, motivate and attract, show that the models are shifting and unstable, promoting understanding of representations and concepts related this molecule. The results indicated that the teaching material is contributed to the objectives outlined and it is possible to discuss the NdC with more depth than found in textbooks to high school students.
