DA SILVA, Samanta Oliveira; TIRADENTES, Cibele Pimenta  and  DOS SANTOS, Solange Xavier. Decomposition and Nutrient Cycling: An Analysis of the Approach of Textbooks and of the Teaching Practice in Secondary Education. Rev. Fac. Cienc. Tecnol. [online]. 2019, n.45, pp.57-70. ISSN 0121-3814.

The purpose of the paper was to verify how the content involving decomposition and nutrient cycling is addressed in Secondary Education (SE) by the teacher and in the textbook. The first stage involved the participation of teachers from the public and private education network of Goiânia, Goiás, who answered a semi-structured questionnaire. In the second stage, the Biology book used in three different schools during the third year of SE was analyzed. Teachers devote three to four classes to address the content, the main difficulties of which are the student's lack of interest, lack of time to prepare the classes/activities, and lack of infrastructure/pedagogical materials to address the issue in a practical way. The most used strategies/didactic resources are the video projector, the board, the textbook, and videos. Only 25% of teachers do practical activities. In the analyzed books, this content is addressed briefly and superficially. Based on this, we perceive the need to work on the decomposition and nutrient cycle contents continuously and contextualized with the reality of the student, thus allowing the relationship and understanding of the processes that make the ecosystem dynamic.

Keywords : biogeochemical cycles; biology teaching; teaching practice; didactic resources.
