Frequência estatística das unidades temáticas da bncc para o ensino fundamental anos finais nas provas da obmep

Abstract

This work aims to map the statistical frequency of the thematic units Numbers, Algebra, Geometry, Quantities and measures and Probability and Statistics, listed in the BNCC (National Common Curricular Base) belonging to the curricular component of mathematics in the final years of elementary school, the from the analysis of the tests applied by OBMEP (Brazilian Mathematics Olympiad of Public Schools). Through a quantitative-qualitative bibliographical research, the tests of the 1st and 2nd phases applied to the final years of fundamental education were analyzed, which corresponds to Level 1 (6th and 7th years) and Level 2 (8th and 9th years), in the period of 2005 until 2022. After the analysis of 832 questions, data collection and respective analysis, it was found that among the five thematic units used in the tests, the most frequent are Numbers and Geometry, respectively with 34.1% and 24.5%, both in the first phase and in the second; with regard to the other three themes Algebra is the one that is least covered. It was evident that the thematic units are complementary to each other, since for the student to solve a problem situation he uses the knowledge acquired in the general context. Despite the differences. In view of these results, it is necessary to reflect on the presence or not of some weakness in the teaching of Mathematics in the final years of Elementary School and to seek more quality in Brazilian education.
