Resumo: | This study had as a principal aim, to investigate the use of different technologies in teaching Molecular Geometry and fundamentally, identify if the software ChemSketch® empowers or opposes the elaboration of more adequate models of chemical structures. To subsidize this study, it was needed to appeal to the quality research which resulted in a study of case. The study of the case was the procedure method which was adopted, aiming a 2nd high school class of 28 students, in a private school in the state of Minas Gerais. The students had the opportunity to deal with different situations while being taught chemistry with the use of technologies, and also to assess the aspects related to learning chemistry. The date was collected through questionnaires; recording of audio and video activities and the elaboration of a planning of the chemistry activities which involved the technology of blackboard and chalk, the technology of using isopor Balls and Sticks and the software ChemSketch®. The analyses were made following 2 perspectives: the evolution of the students due to the use of each of the technologies and the observations and registrations made in the learning environments. Regarding the analyses of the questionnaires, and the observations and registrations in the learning environments it was possible to realize that the development of the activities in a balanced way among the technologies supports the learning to students, due to the fact that it built the structures in a more adequate way. Although the software provided a better view of the molecules structures, the students did not come to a satisfactory performance, which suggests that in the use of the computer, the teacher performs a fundamental role. |

Para subsidiar este trabalho, recorreu-se à pesquisa qualitativa, que se consolidou em um estudo de caso. O estudo de caso foi o método de procedimento adotado, voltado para uma turma de 28 alunos da 2ª série do Ensino Médio, de uma escola particular, do estado de Minas Gerais. Os alunos tiveram oportunidade de vivenciar diferentes situações de ensino de Química, com tecnologias, e também de avaliar sobre seus aspectos relacionados à aprendizagem em Química. Os dados foram coletados por meio de questionários; gravações, em áudio e vídeo das atividades; elaboração de um planejamento das atividades de Química, envolvendo as tecnologias: quadro e giz, bolas de isopor e varetas e o software ChemSketch®. As análises foram feitas segundo duas perspectivas: (i) avaliação dos alunos a respeito da utilização de tais tecnologias e (ii) observações e registros realizados nos ambientes de aprendizagem. A partir dessas análises, é possível perceber que o desenvolvimento das atividades de forma combinada entre tecnologias favorece a aprendizagem para os educandos, visto que, desse modo, eles constroem as estruturas de forma mais adequada. Embora o software proporcionasse uma visualização melhor das estruturas das moléculas, os alunos não obtiveram um desempenho satisfatório, o que sugere que, na utilização do computador, o professor desempenha um papel fundamental.Mestre em Químicaapplication/pdfporUniversidade Federal de UberlândiaPrograma de Pós-graduação em QuímicaUFUBRCiências Exatas e da TerraTecnologiasQuímicaGeometria MolecularQuímica - Estudo e ensinoEnsino médioTechnologiesChemistryMolecular GeometryCNPQ::CIENCIAS EXATAS E DA TERRA::QUIMICATecnologias no ensino de geometria molecularTechnologies in the education of molecular geometryinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisSilva, Rejane Maria Ghisolfi dahttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4768945J1Souza Junior, Arlindo José dehttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4723098E9Mello, Irene Cristina dehttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4728468A1http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4712362D6Franco Neto, João Ribeiroinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFUinstname:Universidade Federal de Uberlândia (UFU)instacron:UFUTHUMBNAILjoao parte 1.pdf.jpgjoao parte 1.pdf.jpgGenerated Thumbnailimage/jpeg1166https://repositorio.ufu.br/bitstream/123456789/17464/7/joao%20parte%201.pdf.jpg300501076782fcfcda1bc9da9a613408MD57joao parte 2.pdf.jpgjoao parte 2.pdf.jpgGenerated Thumbnailimage/jpeg1536https://repositorio.ufu.br/bitstream/123456789/17464/8/joao%20parte%202.pdf.jpgb434db9d0cf8e00514b32be1ef161b3cMD58joao parte 3.pdf.jpgjoao parte 3.pdf.jpgGenerated Thumbnailimage/jpeg1570https://repositorio.ufu.br/bitstream/123456789/17464/9/joao%20parte%203.pdf.jpg85ce8e5f449f8063fa7c6e9972b2a2ffMD59ORIGINALjoao parte 1.pdfapplication/pdf908647https://repositorio.ufu.br/bitstream/123456789/17464/1/joao%20parte%201.pdfad947298ae0ceba467b78e62f474485cMD51joao parte 2.pdfapplication/pdf1885821https://repositorio.ufu.br/bitstream/123456789/17464/2/joao%20parte%202.pdfa9f8b5af7584c212df3bbed15b2919f2MD52joao parte 3.pdfapplication/pdf1093618https://repositorio.ufu.br/bitstream/123456789/17464/3/joao%20parte%203.pdf918313e31d66513ef4907d59726e4fe5MD53TEXTjoao parte 1.pdf.txtjoao parte 1.pdf.txtExtracted texttext/plain74784https://repositorio.ufu.br/bitstream/123456789/17464/4/joao%20parte%201.pdf.txtb054b650fc4d8d140203e28bbadaa2f9MD54joao parte 2.pdf.txtjoao parte 2.pdf.txtExtracted texttext/plain52260https://repositorio.ufu.br/bitstream/123456789/17464/5/joao%20parte%202.pdf.txt9b86575b712de61220df408985ad8732MD55joao parte 3.pdf.txtjoao parte 3.pdf.txtExtracted texttext/plain40062https://repositorio.ufu.br/bitstream/123456789/17464/6/joao%20parte%203.pdf.txtd15093029e64ed1314c92e1b861abcb6MD56123456789/174642016-06-23 04:51:34.25oai:repositorio.ufu.br:123456789/17464Repositório InstitucionalONGhttp://repositorio.ufu.br/oai/requestdiinf@dirbi.ufu.bropendoar:2016-06-23T07:51:34Repositório Institucional da UFU - Universidade Federal de Uberlândia (UFU)false |
