O uso do solo com enfoque CTS nas aulas de ciências no ensino fundamental (fase 1)

Abstract

It becomes important to think about the relationship between the human being and the environment, subsidizing such discussion, we tried to develop in classroom a work in sciences teaching on a contextualized manner, emphasizing activities based on scientific and technological alphabetization, through the focus: science, technology and society, in order to provide to students the preparation they need to deal with technologies’ breakthroughs, considering their impacts towards responsible and conscious attitudes. This research purpose is an alternative to the traditional teaching of sciences, looking for answers concerning the following questions: “What are the contributions of the STS approach to the sciences teaching on the theme soil to students of 5th grade (elementary school – stage 1)? We have tried to answer this question by analyzing the contributions that sciences classes in the STS type can give to the students?” This qualitative-interpretative nature research was developed in a public school, in the city of Ponta Grosse, reaching 30 students. It (the research) happened in 2018, during weekly meetings, totalizing a 20-hour intervention. Through the identification of the learner’s former conceptions on soil, were developed, applied and analyzed 10 class plans about the theme soil, in the STS approach, data were collected during classes through the teacher’s analysis and perception. The obtained data were joined into three categories: former conceptions (what students know about the soil), we perceived soil problems through filming made by themselves, such as erosion and pollution in the place. The other two categories emerged from the data analysis in the classroom, scientific and technological alphabetization: possibilities of the STS approach, environmental education and ethic values that aimed a STA concerning a citizen towads ethic values. Approach STS, defended in this work, has taken to discussions in the school, to develop learning. For a STA the educative efforts led to social activism, a change of attitude, for the student to be more active in his society. The resulting plannings from this research are available to other teachers who want to apply STS in their classes.
