Estudando os ciclos biogeoquímicos uma proposta de sequência didática para o ensino de biologia

Abstract

The central objective of this work was to analyze the contribution of the didactic sequence (DS) as a facilitating and potential tool for the teaching and learning process, specifically the contents of the Deepening Curricular Units (UCA), with a focus on the portfolio, in the area of Science. Nature and its Technologies (CNT), which deals with the training itinerary of Environment, Sustainability and Bioeconomy. For the theoretical foundation of this work, data collection was used through bibliographical research, seeking to verify and analyze important resources for the systematic literature review methodology, which addressed the challenges of the New Secondary Education and the training itineraries; The Trails and In-depth Curricular Units of the state of Amazonas; The importance of biogeochemical cycles for preserving the environment and Didactic sequences as a strategy for teaching biology. Field research took place through the application of a didactic sequence consisting of six stages: Introductory class with a conceptual approach to the content using the Word Cloud technique; Dialogued theoretical class; Bibliographical research on the chemical elements of oxygen and nitrogen and discussion in the classroom; Textual production 1 on the schemes of the biogeochemical cycles of oxygen and nitrogen; Practical class with the construction of a closed terrarium as a demonstrative representation of biogeochemical cycles within an ecosystem and Textual production 2 of biogeochemical cycle schemes. The research location was the Escola Estadual Cívico Militar Dom Gino Malvestio, in the Municipality of Parintins/AM, implemented in the 2nd year high school class made up of 35 students. Through the analysis of the results obtained, we can conclude that the well-structured and organized SD can be an excellent teaching tool used by teachers as a way of implementing it in a progressive and coherent way to facilitate understanding and contextualization of the themes covered in the UCA.
