Quais os caminhos da água no corpo humano? O ensino de biologia por meio de uma sequência didática na educação de jovens e adultos

Abstract

Understanding the complexity of the human organism and establishing the necessary connections is a significant challenge for students. The purpose of this work was to develop an investigative Didactic Sequence (DS) about the path of water in the human body and evaluate the use of this DS as a learning facilitator. Eight students enrolled in the third module of the Biology discipline participated in the research, aged between 20 and 51 years old, from the Education for Youth and Adults modality at the João Guimarães Rosa State Center for Continuing Education – CESEC. The activity was developed in 4 moments: 1 – Verification of students' prior knowledge, 2 – Expository and dialogued class, 3 – Text production, 4 – Practical class. After the activities, students assessed DS using a questionnaire. The results revealed that, initially, the students had some understanding of the subject covered, but with gaps and a lack of organization of the content. After the dialogued class and the research, it was observed that the structuring of the answers was more elaborate and complete. When producing the text, it was seen that only 3 students were able to write in a logical and correct sequence, explaining the participation of systems in the absorption, transport, and excretion of water. In relation to the practical class, the students participated actively, and it was possible to see that knowledge on the topic was built. The DS assessment demonstrated that students felt challenged, were curious, reported gaining knowledge, and that in the investigative process, they were able to analyze and reflect on the topic addressed. We conclude that this work contributed to the students' understanding of the pathways of water in the body, interconnecting the digestive, circulatory, and excretory systems. It enhanced the understanding of how these systems participate in the process of absorption, circulation, and elimination of water, in addition to providing active participation by students, contributing to the construction of their own knowledge.
