O uso de aulas práticas como ferramenta facilitadora na aprendizagem dos alunos sobre o conteúdo de bactérias no ensino fundamental

Abstract

Bacteria are microscopic organisms essential for maintaining life on the planet, performing important functions in various natural processes, such as the decomposition of organic matter and the fermentation of food. Despite their ecological and biotechnological relevance, these microorganisms are still rarely addressed in schools or, when they are, they are usually portrayed only as disease-causing agents. Teaching about bacteria in a clear, accessible, and contextualized way is fundamental for students to better understand the role these organisms play in daily life and in nature. Activities such as modeling bacterial structures using modeling clay, as well as producing culture media, are examples of practical, didactic, relevant, low-cost, and easy-to-apply lessons that can make science education more attractive, dynamic, and meaningful. This study investigated the contribution of these practices to the learning process of students from a public school located in the city of Itaueira-PI. The results obtained demonstrate that practical classes are effective tools in microbiology teaching, providing greater interest, engagement, and understanding on the part of the students by allowing direct and concrete contact with microorganisms present in everyday life.
