Abstract

The main objective of this research was to investigate with Elementary School II teachers the difficulties that students have in relation to Statistical Education, with regard to the interpretation of graphics. The study was developed with teachers of Elementary School II of Vale do Mamanguape/PB in state and municipal schools under the following research problem: Reading and interpretation of graphics. The main theorists who supported the research were Walichinski (2014) and Damin (2014). The methodology adopted in the development of the research regarding the approach to the problem was classified as qualitative, in relation to the objectives, descriptive research was used, and in relation to technical procedures, bibliographic and survey research was used, since we applied a questionnaire together with teachers via Google Forms. The survey results revealed that it was possible to observe the importance of investigating, exploring and understanding that even teachers giving maximum importance to the content, students find it difficult to assimilate and interpret graphs of questions that involve simple reasoning. It is also worth mentioning that the research showed that textbooks do not adequately develop the subject and most teachers do not use laboratories to teach classes and are not aware of applications that create graphics to be used in classroom activities. Emphasizing that teachers reported not having dualities to create activities and those who use applications highlighted the Excel Spreadsheet. Therefore, a didactic sequence was proposed in order to minimize the difficulties raised by the research.
