Diferentes recursos didático-pedagógicos no ensino de biologia: aproximando os conhecimentos científicos do cotidiano dos estudantes

Abstract

This study presents as its central theme the importance of using different didactic tools to overcome the learning difficulties in abstract content such as Cellular and Molecular Biology in the elementary and high school. The didactic resources offer to motivate students in the teaching-learning process, represent an alternative to overcome the exclusive use of the textbook as research material, reading for students and lessons planning for teachers. The thesis is divided in four chapters presented in the form of articles. The first chapter presents an investigation about behavior, acceptance and performance of students in high school facing the use of Information and Communication Technologies (ICT). Allied ICT analyzed the applicability of practical activities in teaching Biology to support the introduction of computer resources. Chapter two investigates whether students motivated by the use of different teaching strategies to better understand about organization and functioning of the cell. In the third one investigates the use of different didactic resources (practical class with microscope and historical replicas, reading comic books and model building) in understanding of Cell Biology for students of elementary school and whether the program about cell teaching is really suitable. The fourth chapter examines whether the program about cell teaching is worked differently in the elementary and high school and which idea that students have about Cell Biology at the different levels of education. The ICT, through the webquest tool, proved to be an important didactic resource for teaching Molecular Biology, as well as motivated and instigated the students to build your knowledge. Moreover, the webquest presented applicability when combined with practical activity of DNA extraction. The different didactic resources had an important role in the student s motivation. Besides motivating, the different teaching tools helped in learning when the Cell Biology was related the student s daily life. The results indicated that the cell teaching is taught similarly in the elementary and high school. There was no greater maturity and conceptual evolution in high school, because the level of response complexity was similar to that found in elementary school. Thus, the didactic-pedagogic resources may be strategies important to stimulate students' curiosity, the desire for discovery and knowledge.
