Enem 2022, Visual impairment, Multivariate statistical analysis, Inequality in the learning processAbstract
The objective of this study was to identify the variables that may influence the scores of visually impaired candidates in the 2022 edition of the Brazilian National High School Exam (Enem), with an emphasis on performance in the writing section, in order to support more effective and inclusive interventions by public authorities and policymakers. The study identified patterns and trends related to socioeconomic variables such as access to technology, family income, school infrastructure, and regional characteristics. The methodology applied score standardization in standard deviation units, Multiple Correspondence Analysis (MCA), clustering using the K-Means method, and Linear Discriminant Analysis (LDA). The statistical methods revealed significant variations in essay scores, which were associated with geographical and socioeconomic factors, as well as inequalities in access to remote education. Social isolation during the global pandemic also directly impacted the performance of these students. The study suggests the implementation of public policies aimed at this specific group with total or partial loss of visual capacity to minimize inequalities and promote greater balance in the learning process.
