O estudo dos elementos químicos numa abordagem ciência, tecnologia e sociedade

Abstract

This work aimed to develop the study of the chemical elements in an approach Science, Technology and Society, to contribute to the formation conceptual, procedural and attitudinal more critical of the two students. Grade school, School of Basic Education Barão de Antonina in the town of Mafra, the state of Santa Catarina. The specific objectives of the research were to identify the students 'design partners on relations of science and technology, raise the students' prior knowledge about chemicals, develop activities that promote the study of the chemical elements in an approach Science, Technology and Society (CTS ) using articles submitted and selected in Journal of Science Communication (RDC) and introduce an educational product, in terms of Didactic Guide, which can be disseminated, analyzed and used by other teachers of basic education - high school, the discipline of chemistry, as an example of a pedagogical approach CTS. The methodological approach that guided this study was the interpretative nature of qualitative research with participant observation. The technique of data collection was focused on participant observation, field diary notes on, students' written productions, photographs and film footage, these segments were transcribed. The survey data were collected and analyzed, initially by means of verification of previous conceptions of twenty-one students (21), wrapped in the process, taking into account the relationship to the theme presented. This factor allowed the targeting of activities to categories of analysis, which were bounded by an exploratory stage and an action research, in which students had the opportunity to participate in an active, cooperative, intervening in the construction of the study, with their knowledge , suggestions and reflections on the social relations of scientific and technological knowledge. Thus it was possible to develop the process of collective construction of the proposed approach to the theme suggested, because as the final product has a guide to teaching, in which the activities listed. The main perceptions of research contributions bring to ratify the essential actions to implement the act of teaching and learning, in order to improve teaching practices in the teaching of chemistry as well as the continuity of reflexive stance on Science and Technology, for educators and students , enabling a productive educational journey linked to the formation of the citizen of the XXI century.
