Trigonometria no ensino fundamental e sua importância nos exames classificatórios do IFPI

Abstract

This study aimed to investigate the content of Trigonometry in elementary education as presented in the curriculum of the municipality of Teresina and its importance for the entrance exams of the Federal Institute of Piauí (IFPI). The methodology adopted was qualitative research of an exploratory and documentary nature. For this study, priority was given to the Curriculum Guidelines of the Municipality of Teresina (2018) and the tests related to the IFPI Entrance Exams, in the period of 2019-2024. The choice of this time frame for the IFPI exams is related to the period of implementation of the current Teresina curriculum. The results indicate that among the contents of Trigonometry, Trigonometric Ratios are not present in the Teresina Curriculum Guidelines, which directly impacts the performance of public school students in the IFPI Entrance Exams. It is important to highlight that, among the topics covered in the exams, Trigonometric Ratios are required, thus creating a mismatch between the content of the municipal school curriculum and the demands of the entrance exams. Finally, the research made it possible to understand the impacts of the absence of this content on the students' success in the entrance exams.
