A elaboração de itens de matemática no contexto do SAEPE: Um estudo prático sobre o descritor D12 para o 9º ano

Abstract

This study investigates the process of developing a mathematics item within the context of the Pernambuco Educational Assessment System (SAEPE), focusing on descriptor D12 for the 9th grade of elementary school, related to calculating the perimeter of plane figures. The research aimed to apply the knowledge present in the CAEd Item Development Guide to construct an original assessment question focused on the aforementioned descriptor. The work developed is qualitative and documentary research, based on the analysis of official documents, such as the CAEd Item Development Guide, the SAEPE Reference Matrix, and materials related to Item Response Theory (IRT). The research is also based on authors who discuss educational assessment, geometry teaching, and learning difficulties involving area and perimeter. As a result, an item was developed consisting of support material, a statement, instructions, and alternatives with distractors constructed based on recurring errors identified in the mathematics education literature, and an answer key. Therefore, the careful creation of assessment items contributes to more accurate diagnoses of mathematics learning and to the improvement of assessment practices in the school context.
