Neste estudo apresentamos algumas reflexões sobre um trabalho reali-zado em salas de aula de oitavas séries de ciências, realizado por turmas da licenciatura em Ciências Biológicas, especificamente nas disciplinas de Metodologia e Instrumentação para o Ensino de Ciências. O objetivo principal é criar possibilidades dos licenciandos vivenciarem o cotidiano de uma escola pública, desenvolvendo uma intervenção didática numa perspectiva discursiva na educação CTS. Dessa forma, nossas referências têm se pautado na análise do discurso e no funcionamento da linguagem em aulas de ciências e tecnologia. São apresentados e discutidos alguns resultados dessa proposta de formação inicial de professores e a pertinência da abordagem temática para a construção de sentidos sociais-culturais e ambientais do conhecimento científico contextualizado.

In this study, we present some reflections on a work in classrooms of eigth grade, done by a class of Biological Sciences, specifically in the disciplines of Methodology and Instrumentation for the Science Teaching. The main goal is to create opportunities for future teachers to experience daily life in a public school, developing an intervention in a didactic discursive perspective in STS education. Thus, our references have been based on analysis of speech and functioning of language in science and technology classes. We presented and discussed some results over the initial education of science teachers and the relevance of thematic approach for the construction of social-cultural and environmental meanings of the contextualized scientific knowledge.

In this paper we present the Science, Technology and Society (STS) approach and the Paulo Freire's philosophy of education and their relations hips. We explore three points of convergence without necessarily to exhaust the possibilities of articulation between these pedagogical theories. These points are not handling in an isolated way since they certainly have connections and dialogue with each other. They are: (i) the thematical approach and the selection of didactical material; (ii) the interdisciplinary perspective of the pedagogical work and its role in the teacher formation; (iii) the role of the teacher in the process of teach and learning and in the formation of citizens. We understand that this proposal of articulation benefits both: to the STS approach is provided a solid and coherent educational basis - some that not always is present in their proposals - and on the other hand to the Freire's method (and its applications to the science teaching) by creating opportunity of discuss topical themes with social, politics and economics dimension, especially in the context of science and technology education.

En este artículo se presentan unas relaciones teóricas entre el enfoque CTS y la filosofía educacional de Paulo Freire. Se explotan tres puntos de convergencia que por supuesto no agotan las posibilidades de articulación entre estas frentes pedagógicas y que no se quedan cerradas en sí mismas sino que dialogan entre sí. Son ellos: (i) el abordaje temática y la selección de los contenidos y materiales didácticos; (ii) la perspectiva interdisciplinar del trabajo pedagógico y el papel de la formación del profesorado; (iii) el papel del educador en el proceso de la enseñanza y aprendizaje, y en la formación para el ejercicio de la ciudadanía. Tenemos en cuenta que la articulación de estas proposiciones educacionales es una ganancia para los dos: para el enfoque CTS por conferirle una base educacional sólida y coherente (no siempre explícita en el enfoque CTS) y, a la vez, para la pedagogía y método Paulo Freire (y sus desdoblamientos en la enseñanza de las ciencias) por hacer oportuno el abordaje de temas actuales de dimensión social, política y económica, en particular en el ámbito de la enseñanza de la ciencia y la tecnología.
