Potencial de alfabetização científica em nanotecnologia nas coleções do livro “química ser protagonista” nos PNLD de 2012 a 2021

Abstract

Nanoscience and Nanotechnology are central areas of scientific research, stimulating the development and innovation of various sectors. And yet, despite its recognized importance, the topic of Nanotechnology is not adequately addressed in basic education. Therefore, this work proposed to analyze the theme of Nanotechnology in the collections of the book “Química Ser Protagonista” of the National Textbook Program (PNLD) in the three years from 2012 to 2014, 2015 to 2017, 2018 to 2020 and 2021 to 2023 in relation to Scientific Literacy Indicators – IAC proposed by Pizarro (2014) and the analysis instrument “Thematic Axes in Nanotechnology”, proposed by Pereira, Soares and Silva (2023). For the study, conventional questions, entrance exam and ENEM questions, projects and complementary texts were analyzed. The questions resolved in the books were not considered for the purposes of the corpus of this investigation. With this work, we sought to evaluate whether there was the development of potential indicators of scientific literacy over the course of each threeyear period and, also, the materials were evaluated against the Nanotechnology thematic axes, so that the didactic potential of these collections for teaching could be identified. Chemistry in high school. Using the analysis instrument, a study was also carried out on the ENEM issues (2018-2022), to find out how the topic of nanotechnology is being addressed throughout these last five editions in the area of Natural Sciences and their Technologies. With the results obtained in the work, it was possible to identify gaps when it comes to the topic of nanotechnology, both in the Scientific Literacy Indicators and in the thematic axes. However, this research opened doors for the development of new projects, such as the development of complementary material on the topic studied.
