EXAME NACIONAL DO ENSINO MÉDIO: O QUE REVELAM OS DADOS POR ÁREA DE CONHECIMENTO NUM PERÍODO DECENAL?

The present paper had the general objective of exposing and analyzing the context of the general averages of the National High School Examination (ENEM) by area of knowledge, through data collected from the website of the National Institute of Educational Studies and Research Anísio Teixeira (INEP), over 10 years (2009-2018). It presents a brief analysis of the trajectory of secondary education in Brazil, as well as the idealization, implementation and reformulation of ENEM and the way in which the evaluation of this exam occurs. We started from the quantitative approach using descriptive statistics as a method of analysis of the collected data and carried out an exploratory research about the survey of the following areas of knowledge, namely: Languages and Codes and their Technologies, Mathematics and their Technologies, Human Sciences and their Technologies and Natural Sciences and its Technologies. For the collection, we performed a critical analysis of the data, using the technological tool Microsoft Excel 2013, employing some descriptive measures through the arithmetic mean, variance and standard deviation. The data reveal a discreet movement in relation to the average grades in all areas of knowledge, with a noticeable gap in the four areas of knowledge between the minimum, average and maximum grades, which allows us to conclude that there is a data alignment, ie, little progress in education in quantitative terms during such period.
