Formação continuada em ensino de nanociência e nanotecnologia: estratégias formativas e elaboração de sequências didáticas para a educação básica

Abstract

In recent decades, scientific advancement has profoundly transformed our understanding of the world, especially in the interdisciplinary field of N&N. However, discussions about the benefits and risks associated with these technologies remain divergent. Given the growing importance of N&N, the challenge arises of integrating this knowledge into teacher education, aiming to introduce contemporary topics into basic education. To address this challenge, this study aims to analyze the contributions of the extension course to the continuing education of teachers on N&N, resulting in the elaboration of didactic sequence (DS) proposals, developed by the participants and applicable to basic education. The research adopted a qualitative approach, structured as a case study, carried out during the training sessions of the extension course “Exploring the Nano Universe in Education,” which targeted 17 science or physics teachers/licentiates participating in the MNPEF. The study was conducted during the 2024.1 and 2024.2 semesters at FECLESC, an advanced campus of UECE, located in Quixadá, Ceará, Brazil. Data collection included a RSL, the application of a diagnostic questionnaire to identify the specific training needs of the participating teachers regarding the teaching of N&N, and the analysis of the DSs developed by the participants. The comparative analysis between the questionnaire responses and the DS proposals revealed that the introductory notions of N&N, assimilated during the extension course, significantly improved participants’ understanding of these concepts, which was reflected in the development of more consistent DS proposals. However, it was also evident that some teachers still had difficulties integrating N&N topics into their teaching practices, even after the training, highlighting the need for long-term continuing education in the teaching of N&N.
