A influência dos parâmetros curriculares nacionais (pcn) nas questões de química do exame nacional do ensino médio uma análise detalhada com foco nas ligações químicas (2020-2023)

Abstract

This study investigates the influence of the National Curricular Parameters (PCN), especially its component for High School (PCNEM), on the Chemistry questions of the National High School Examination (Enem), from 2020 to 2023. The research is characterized as a qualitative case study, with content analysis of the Enem Chemistry questions that address this topic during this period. The results demonstrate that the PCN exert a significant influence on the preparation of Enem Chemistry questions, with an emphasis on content such as types of chemical bonds, properties of substances and chemical reactions. The questions have different levels of difficulty and require students to have different cognitive skills, from knowledge to evaluation. The analysis highlights the importance of alignment between the PCN and Enem to guarantee quality training for high school students.
