BIOTECNOLOGIA EM SALA DE AULA: experiência prática em uma escola pública de Floriano-PI

Abstract

Biotechnology is present in various sectors of society and plays a fundamental role in the development of products and processes that utilize organisms or biological components. This area contributes to advances in fields such as health, agriculture, the environment, and industry, impacting daily life through medicines, fermented foods, biofuels, and cosmetics. In this context, the teaching of Biotechnology becomes relevant by enabling students to understand its applications in everyday life, fostering critical and investigative thinking. The objective of this work was to analyze the contribution of practical and playful activities in the teaching of Biotechnology, based on the application of the educational game "CSI Biotec – The Genetic Enigma of the School" with 8th-grade students from a public school in Floriano-PI. The research, with a descriptive and explanatory approach, used an Investigative Teaching Sequence (ITS) organized in four stages, seeking to promote contextualized learning about DNA and Biotechnology. The proposal allowed students to understand everything from simple processes, such as the extraction of DNA from fruits, to more complex applications present in the investigative narrative of the game. Analysis of the pre- and post-tests revealed significant progress in knowledge (g ≥ 0.70), demonstrating the effectiveness of SEI in understanding the content. The results also highlighted the importance of relating biotechnological knowledge to everyday life, contributing to a more critical and conscious view of one's role in society.
