Digital technologies in Teaching Chemistry / Tecnologias digitais no ensino de quÃmica

Nilson Fonseca Miranda 04 September 2007 (has links)
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / This work analyzes the speech of the Chemistry professors of Universidade Federal do Piauà about the use of digital technologies, educational sites and softwares, conceived as tools applied to the teaching of Chemistry. It also analyzes the usage of softwares in the classroom: Spartan; origin; organic Chemistry II and the sites: nautilus; chemkeys; ucs; qmc.ufsc and quark. The main goal is to verify how the use of such tools contribute pedagogically to the teaching/learning in the area of Chemistry. The theoretical contribution used supports that the digital technologies themselves donât stablish nor catalyze the changes on the pedagogical practice, but the way which it is conceived by the teacher and the way it is used at the teaching system, intensifies the development of successive innovations and later change in the posterior change in the educational paradigm. As for the development of this research a qualitative methodology was used in order to make the search of chemical knowledge possible bearing in mind that this production also comes from the exchange, the socialization, sometimes conflicting, that the different agents involved promote when theyâre facing and representing their realities, completing them with various definitions. In this sense, (a) the speech of the teachers obtained through interviews, (b) the data about educational sites and softwares used on the chemistry teaching obtained through a grid of analysis produced for this purpose have been analyzed. The result of the collected data analysis aims at some positive reasons that justify the use of digital technologies on the Chemistry teaching: quickness and efficiency in the obtainment of information; access to new acquirements and higher agility at learning. Besides, it makes the simulation through virtual experiments possible, gives the opportunity to teachers and students to acquire modern information and possibilities of access to new acquirements. / Este trabalho analisa o discurso dos professores de quÃmica da Universidade Federal do Piauà acerca do uso das tecnologias digitais, sites e softwares educativos, concebidas como ferramentas aplicadas ao ensino de quÃmica. Analisa tambÃm a forma de utilizaÃÃo na sala de aula dos softwares: spartan; origin; quÃmica orgÃnica II e dos sites: nautilus; chemkeys; ucs; qmc.ufsc e quark. O objetivo fundamental à verificar como o uso dessas ferramentas contribui pedagogicamente para o processo de ensino/aprendizagem na Ãrea da quÃmica. O aporte teÃrico utilizado sustenta que as tecnologias digitais por si sà nÃo estabelece, nem catalisa mudanÃas na prÃtica pedagÃgica, mas a forma como à concebida pelo professor e utilizada no sistema de ensino, potencializa a eclosÃo de sucessivas inovaÃÃes e posterior mudanÃa no paradigma educacional. Para o desenvolvimento desta pesquisa foi utilizada uma metodologia qualitativa a fim de possibilitar a busca do conhecimento quÃmico compreendendo que essa produÃÃo tambÃm se elabora na troca, na socializaÃÃo, Ãs vezes conflituosas, que os diferentes atores envolvidos promovem ao enfrentarem e representarem suas realidades, preenchendo-as de significaÃÃes diversas. Neste sentido, foram analisados: (a) o discurso dos professores obtido atravÃs de entrevista; (b) os dados sobre sites e softwares educativos utilizados no ensino de quÃmica obtidos atravÃs de uma grade de anÃlise produzida para esta finalidade. O resultado da anÃlise dos dados gerados aponta para algumas razÃes positivas que justificam a utilizaÃÃo das tecnologias digitais no ensino de quÃmica: rapidez e eficiÃncia na obtenÃÃo de informaÃÃes; acesso a novos conhecimentos e maior agilidade no aprendizado. AlÃm disso, possibilita fazer simulaÃÃo mediante experimentos virtuais, oportunizando professores e alunos a adquirirem informaÃÃes recentes e possibilidades de acesso a novos conhecimentos.
