Análise do conteúdo sobre espécies invasoras nos materiais didáticos de ensino médio

Abstract

Invasive species are a problem that has been considered the second biggest threat to the planet's biodiversity. As this problem is little known by the population in general, people may even be contributing to the spread of invasive species in ecosystems, causing damage to native species. This paper aims to analyze and explore the discussions that can be made through the reading of didactic materials used by high school students about the teaching of invasive exotic species. To this end, we analyzed the teaching materials regarding the presence and quality of the content related to invasive species. Textbooks from three educational systems, three collections of textbooks, and the nine first pages on the internet after a Google search on "invasive species" were selected. At the end of the work it could be observed that there are differences between the concepts used by some of the materials, and it was observed that in 4 of the 15 materials analyzed, the theme is worked in a way that contains conceptual errors or too shallow or technical information, which caused the materials to be considered unsatisfactory, while other 5 had the quality considered as partially satisfactory and, finally, 6 were considered satisfactory due to their language, clarity and veracity of information. The use of teaching materials and resources with very technical, shallow, or incorrect information ends up contributing to the spread of invasive species, since the student may not be able to identify this problem when there is a deficit in teaching the subject.
