A importância dos microrganismos para a sustentabilidade ambiental: sequência didática com enfoque investigativo

Abstract

Currently, there has been much discussion about the actions of humankind on Earth and the consequences of their attitudes for the future of life on the planet. The correct disposal of organic waste is fundamental for environmental balance, and microorganisms are an essential part of this process. Recognizing the need for improvements in the teaching-learning process about microorganisms, this project sought to combine Microbiology with Ecology. This project aimed to develop, apply, and evaluate a didactic sequence based on investigative teaching to facilitate student learning about microorganisms and their importance, using composting. The methodology was based on theoretical and experimental investigation through the application of a didactic sequence referencing investigative teaching and data instruments in the form of questionnaires applied to students and evaluating teachers. After the application of the didactic sequence, it was observed that the exploration of the Microbiology/Microorganisms theme combined with the development of composting made learning more meaningful, stimulating student participation. Nine compost bins were made, and humus formation could be observed in one of them. The students demonstrated progress in understanding the content, a moment evidenced mainly during the elaboration of reports and in the final discussion where they could report their perceptions and their learning.
