Ecossistemas marinho, manguezal e recifal: análise dos conteúdos de livros didáticos de ciências e biologia publicados no período de 2012 - 2016

Abstract

One of the main didactic resources used by teachers and that can play an important role in the teaching significance of Sciences and Biology by the students is the textbook, and for having considerable limitations and a reflexive analysis is necessary in relation to the contents approached. This work had as general objective to analyze the contents of the textbook of Science (6 th to 9 th year) and Biology (High School), approved by the PNLD in the period from 2012 to 2016, referring to the “Marine, Mangrove and Recifal Ecosystems”. The study was characterized as a Qualitative approach, where it was used as theoretical and methodological assumptions elements of the Biographical/Documentary research and for the analysis of the data, Categorical Content Analysis being categorized and analyzed 132 works published in the period between 2012 and 2016, of wich 42 are of Biology and 90 of Sciences, of wich only 26 and 31 that approached the themes proposed respectively. As main results, we observed several conceptual errors related to the Mangrove, being the category adaptions of the plants, as example “roots-anchors” with frequency of 14,8% in textbook of Biology and 20,6% in Sciences. Regarding the Marine Ecosystem, most of the biology works presented correct and complete information, but the textbook of Sciences showed lack of information. The Recifal environment also presented conceptual errors, with respect to its information and fauna of vertebrates little diversified with only 4 constituents in textbook of Biology and 5 in Sciences. Therefore, it can be affirmed that most of the analyzed works, wich contain the theme approached, presented some flaw on the subjects mainly conceptual errors, approaching the content incompletely and/or absent, not reaching the criteria established by the PNLD.
