Análise dos microdados do ENEM a partir da teoria da resposta ao item

Resumo

Since 2009 the Brazilian National High School Examination (Exame Nacional do Ensino Médio - ENEM) started utilising the Item-Response Theory (IRT) to determine students scores. Since 2009 the Brazilian National High School Examination (Exame Nacional do Ensino Médio - ENEM) started utilising the Item-Response Theory (IRT) to determine students scores. The ENEM micro data published by INEP (Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira) contains detailed information about all instalments of the examination. But there is no data directly related to the actual IRT implementation besides the scores themselves. In this work we analyse the ENEM micro data under the the light of the three parameter logistic model of IRT, with two main goals: 1) To generate more information on the implementation of IRT used in ENEM, particularly estimating the parameters used for each question of the examination; 2) Treat the information gathered and suggest different ways of presenting it in order to improve the understanding of the effect of utilising IRT over the examination scores. The item estimation methods may be used, as an example, to create simulated examinations and calculate the scores on the same scale used by ENEM, with the same methodology, allowing for a better assessment of students preparing for the examination.
