Ensino de trigonometria: desafios e estratégias de ensino no 9º ano do ensino fundamental

Abstract

This monograph presents a research aimed at representing the scenario in which the context of content acceptance and the degree of difficulty presented by 9th grade students in public schools are discussed, in relation to the teaching of Trigonometry. Therefore, it is argued that the approaches used by the teacher need to include problem situations from the individual's daily life. Bibliographical research was conducted that discussed the challenges encountered in the teaching-learning process of the content, characterizing the strategies for teaching Trigonometry in the 9th grade of Elementary School that the teacher should use when solving problem situations from the student's daily life, thus favoring practical teaching, related to the student's reality. A brief history of Trigonometry was presented, as well as its development over the centuries. The work also highlights the presentation of Trigonometry in Elementary School, conceptualizing the Right Triangle and Trigonometric Relations at this stage of Basic Education. The work focused on the approaches and strategies that can be used so that the student has greater use in the classroom in relation to the content of Trigonometry, since textbooks have increasingly limited or absent resources regarding the teaching of Trigonometry, teaching strategies thus causing learning difficulties. Through exploratory field research at the Marinha Rocha Municipal School in Balsas - MA, developed through the qualitative approach, it was possible to conceptualize the approaches of the mathematics teacher in the classroom and the students' use of Trigonometry.
