Abstract in Portuguese
A utilizacao de textos de divulgacao cientifica no ensino formal tem sido discutida por pesquisadores da area de educacao em ciencias. Tais discussoes sugerem que esses textos podem funcionar como instrumento de motivacao em sala de aula, organizando explicacoes e estimulando debates de modo a ampliar o universo discursivo dos estudantes. Nesta perspectiva, foi aplicada uma proposta de ensino pautada no uso de textos extraidos do livro de divulgacao cientifica Tio Tungstenio: Memorias de uma Infancia Quimica, de Oliver Sacks. O objetivo da proposta foi investigar o funcionamento de tais textos, a producao de sentidos por eles proporcionada e suas contribuicoes para o ensino superior de quimica. A proposta, que envolveu a producao de textos e elaboracao de perguntas pelos alunos sobre conteudos presentes no livro, foi aplicada em uma disciplina oferecida a estudantes de graduacao em quimica. Os dados obtidos foram analisados segundo a Analise do Discurso de linha francesa, como tem sido divulgada por Eni Orlandi, especialmente as nocoes de tipologia do discurso e autoria. A analise dos resultados com relacao a tipologia revelou, nas questoes formuladas pelos alunos, deslocamentos do discurso pedagogico, predominantemente autoritario, para um discurso polemico. Quanto a autoria, na producao dos textos, foi percebida a utilizacao de tres tipos de repeticao - empirica, formal e historica. A maioria dos alunos fez uso da repeticao historica, tipo de repeticao que indica o posicionamento dos alunos como autores de seus textos. A analise dos resultados indicou que os textos de divulgacao cientifica funcionaram como mediadores para a colocacao de posicionamentos incomuns em aulas tradicionais do ensino superior de quimica, o que sugere a viabilidade da proposta neste nivel de ensino.

Abstract in English
The use of scientific divulgation texts in formal education has been discussed by researchers in the field of Science Education. Such discussions suggest that these texts can be an instrument of motivation in the classroom organizing explanations and stimulating discussions in order to expand the students discursive universe. Thus, a teaching proposal was implemented based on the book Uncle Tungsten: Memories of a Chemical Boyhood, by Oliver Sacks. The goal of this proposal was to investigate its understanding, acceptance, and contributions to undergraduate chemistry teaching. The study involved the production of texts and questions by the students about some chapters of that book. The data were analyzed by Discourse Analysis, in its French approach, according to Eni Orlandi, especially the concepts of discourse typology and authorship. The typology results demonstrated transitions from a pedagogic discourse, predominantly authoritarian, to a polemical discourse. The authorship results indicated the use of the three different kinds of repetition (empirical, formal and historical). The historical repetition use demonstrates that the majority of the students played the role of authors. Hence, the scientific divulgation texts act as mediators for nontraditional remarks by the students in undergraduate chemistry classes, suggesting the feasibility of this proposal at this level of education.
