Geometry descriptors with low assertiveness in the 2015 to 2023 editions of the Minas Gerais (Brazil) external assessment
Year: 2025
Type: article
Abstract: The study aimed to problematize descriptors related to Numbers and Geometry, assessed jointly in the 2015 to 2023 editions of the Proeb. The assessment is positioned as a dimension of the curriculum, focusing on the assertiveness results of the 5th grade of Elementary School, 9th grade of Middle School and the 3rd grade of High School in Minas Gerais, Brazil. Data collection took place via access to spreadsheets with student results from the Minas Gerais Educational Assessment Portal. We considered the average assertiveness results per descriptor with the lowest assertiveness results. Analysis of common descriptors indicates an expected progression in complexity, and that skills considered complex in the 5th grade become structuring in the 9th grade and essential in the 3rd grade. It also indicates that the transition between cycles has not guaranteed the deepening of these skills, generating a cumulative effect of gaps.
