Abordagem CTS e possibilidades de letramento científico no Projeto Água em Foco: tipos textuais e linguagem científica

Abstract

The scientific literacy is a subject for discussion in official documents and in the community of researchers in science education. In this work we investigate the scientific literacy of high school students through the appropriation of scientific language in different types of textual sequences. In order to do that, we analyze some texts produced by students of a public state school i n Belo Horizonte, who have participated in the Project Water in Focus. This project proposes to discuss some chemical concepts from an approach that considers the relationships between science, technology and society that permeate discussions on water quality in urban environments, such as Pampulha Lake, postcard of Belo Horizonte. To examine the texts produced by students, we use initially the NVivo® software that permits coding passages of texts and searching for words, phrases, etc. The analysis of the texts took into account the total number of words; the presence of physical, chemical and biological parameters; the themes developed in the texts; and also the kinds of textual sequences. This analysis indicates different degrees of appropriation of the scientific language and different scientific literacy levels among the students.
