A importância da estatística no ensino médio

Abstract

The main objective of the present research was the analysis of documents, textbooks and ENEM questions in order to verify how they point out the ways to work the content of Statistics within Mathematics in High School. The research will be qualitative, exploratory and based on the principles of action research. Based on these principles, it was decided to review the literature regarding the teaching of Statistics, where it was observed the potential that it presents before the teaching of Mathematics in Basic Education. The legislations investigated point out that each one in their field of interest has the need for complete training, providing students with devices capable of making them full citizens in the physical, cognitive and social-emotional aspects. The next point analyzed was in relation to how the content of the subject in focus, is presented to the students through the textbooks. For this, a survey of the collections used by the colleges was carried out and the most used set of works was verified in the great majority of the institutions. Also, according to the analysis carried out, the same is what contemplates the assumptions contained in the targeted legislation, following the meaning proposed by the authors contained in the literature. After the considerations raised, the ENEM questions were observed, in order to verify the number of them in the use of Statistics when presented in the tests. Also, what were the appropriate content addressed. As a final product of this document, a didactic material to support the teacher was prepared, containing two teaching proposals that are anchored with the support of Microsoft Office Excel Software. These were contextualized on basic contents of Statistics directed to High School.
