Previous issue date: 2007-12-07 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / In the past twenty years, there has been a significant increase of researches about teacher s professionalization. In that context, the investigations concerning teacher s knowledge represent an important contribution, as they aim to identify and to rescue the base of knowledge that sustains the teacher s profession. In particular, the reflections and propositions of Lee Shulman have been constitute a fundamental subsidy to the teacher s professionalization in the sense of
harnessing the pedagogic knowledge to the content s knowledge, establishing the pedagogic knowledge of the content that characterizes and differentiates the teacher and the bachelor in a certain field of knowledge. Among the indispensable knowledge for the Chemistry teacher's professional practice, in this research we have pointed out the pertinence of the knowledge on the use of models in Chemistry classes in the middle and high school. Those knowledges regard the comprehension of students concerning the understanding and models elaborated in science and
the models implemented in the Chemistry teaching, as well as the abilities to plan didactic situations that use models. In this research, we aimed to identify the contributions and barriers during the Chemistry teacher education, in UFRN, in relation to the construction of knowledge that subsidize training teachers in the elaboration of teaching activities that involve the use of models. The investigation was accomplished in UFRN, in the Course of Degree in Chemistry, along with 13 student teachers that studied the subject Practice of Chemistry Teaching. For this research, the following instruments were used: questionnaires with open and closed questions, elaboration of a plan of activities for the Chemistry teaching and an interview to answer the established study s questions. The data was analyzed in an established criteria, classified and tabled. The results showed that the student teachers representations regarding scientific knowledge contemplated, among other topics, the idea of a method for his/her construction. In some cases, the models role was emphasized in that construction, as well as the social dimension in the validation of that knowledge. The scientific models were highlighted by most of the student teachers, as a representation method to explain, understand and interpret the chemical phenomena. On the other hand, the didactic models stood out, in most of cases, as a method of aiding the Chemistry students of the Basic Education to understand the scientific models. The representations regarding those categories contemplated important aspects, although in a
superficial way, reflecting the limitations of reflections during the formative process. In the elaboration of teaching activities that use models, difficulties were evidenced, in the process of plan construction, relative to the didactic structure and to the proposition of activities that contemplated models, although the student teachers have mobilized different elements regarding
the pedagogic knowledge of the content. Such verifications evidence the urge for the teacher development programs to promote changes in the teacher education in order to propitiate, during this process, reflections, discussions and propositions of activities regarding categories
highlighted in this research, contributing to the construction of initial elements regarding the
pedagogic knowledge of the content that will be developed throughout teaching, therefore corroborating to the teacher s professionalization / Nos ?ltimos vinte anos, as pesquisas voltadas profissionaliza??o docente t?m crescido de modo expressivo. Nesse contexto, as investiga??es acerca dos saberes docentes representam uma importante contribui??o, visto que buscam identificar e resgatar a base de conhecimento que sustenta a profiss?o docente. Em particular, as reflex?es e proposi??es de Lee Shulman t?m constitu?do um subs?dio fundamental ? profissionaliza??o dos professores no sentido de atrelar os saberes pedag?gicos aos do conte?do, estabelecendo o conhecimento pedag?gico do conte?do
que caracteriza e diferencia o professor e o bacharel em determinada ?rea de conhecimento. Entre os saberes imprescind?veis ao exerc?cio profissional do professor de Qu?mica, salientamos, nesta pesquisa, a pertin?ncia dos relativos ao uso de modelos nas aulas de Qu?mica nos ensinos fundamental e m?dio. Esses saberes s?o referentes ? compreens?o dos licenciandos acerca do conhecimento e modelos elaborados na ci?ncia e dos modelos adotados no ensino de Qu?mica, assim como as habilidades para planejar situa??es did?ticas que utilizem modelos. Nesta pesquisa, buscamos identificar as contribui??es e entraves, durante a forma??o inicial de professores de Qu?mica, na UFRN, em rela??o ? constru??o de saberes que subsidiem os
licenciandos na elabora??o de atividades de ensino que envolvam a utiliza??o de modelos. A investiga??o foi realizada na UFRN, no Curso de Licenciatura em Qu?mica, junto a 13 licenciandos que cursavam a disciplina de Pr?tica de Ensino de Qu?mica. Para esta pesquisa, foram utilizados os seguintes instrumentos: question?rios com perguntas abertas e fechadas, elabora??o de um plano de atividades para o ensino de Qu?mica e entrevista de modo a responder as quest?es de estudo estabelecidas. Os dados obtidos foram analisados a partir de crit?rios estabelecidos, categorizados e tabelados. Os resultados sinalizam que as representa??es dos
licenciandos referentes ao conhecimento cient?fico contemplavam, entre outras quest?es, a id?ia de um m?todo para a sua constru??o. Em alguns casos, foi ressaltado o papel dos modelos nessa constru??o, bem como a dimens?o social na valida??o desse conhecimento. Os modelos
cient?ficos foram destacados, pela maioria dos licenciandos, como uma forma de representa??o com finalidade de explicar, compreender e interpretar os fen?menos qu?micos. J? os modelos did?ticos foram ressaltados, na maioria dos casos, como uma forma de auxiliar os alunos de Qu?mica da Educa??o B?sica a compreender os modelos cient?ficos. As representa??es referentes a essas categorias contemplaram aspectos importantes, embora de modo superficial, refletindo as limita??es de reflex?es nesse sentido durante o processo formativo. Na elabora??o de atividades de ensino que utilizam modelos, foram evidenciadas dificuldades, no processo de constru??o do plano, relativas ? estrutura did?tica e ? proposi??o de atividades que contemplassem modelos,
embora os licenciandos tenham mobilizado diferentes elementos referentes ao conhecimento pedag?gico do conte?do. Tais constata??es evidenciam a necessidade de que a ag?ncia formadora possa promover mudan?as na forma??o inicial de modo a propiciar, ao longo desse processo, reflex?es, discuss?es e proposi??es de atividades relativas ?s categorias destacadas nesta pesquisa, contribuindo para a constru??o de elementos iniciais referentes ao conhecimento pedag?gico do conte?do que ser?o desenvolvidos no decorrer da doc?ncia, corroborando, dessa forma, para a profissionaliza??o docente
