ANALYSIS OF THE STATISTICS APPROACH IN THE PNLD HIGH SCHOOL MATHEMATICS BOOKS 2018 - statistical literacy
Textbook. High school. Statistical Literacy. Praxeological Organization.
This study is part of the line of research Knowledge and Teaching Practices highlighting the importance of Statistics in student learning, in addition, it considers the textbook as the main instrument used by teachers when planning their classes and as material for study and research by students , so the research has as main objective to analyze two collections of High School Mathematics textbooks, from the National Textbook Program 2018, regarding the Statistics approach and if this approach promotes Statistical Literacy. Theoretically, it will be supported by Statistical Literacy, proposed by Iddo Gal (2002), at the Watson and Callingham (2003) Statistical Literacy levels, in Chevallard's Praxeological Organization (1999) and in works that also analyzed the mathematics textbook. In the analysis, it was also verified whether the collections already had any correspondence with guidelines from the Common National Curricular Base (BNCC, 2018). Qualitative documentary study methodology was used. The sample was intentionally composed of two high school collections recommended by PNLD 2018 - 2020. To perform the analysis, the evaluation instrument with descriptors based on the work of Santos (2017) was used. At the end of the analysis it was found that the Connections to Mathematics collection allows the student to reach the consistent non-critical level, while the Context & Applications collection allows the inconsistent level, depending on the categorization of Watson and Callingham's (2003) Statistical Literacy. Therefore, we found gaps that would be filled if the textbooks met what is recommended by researchers in the field of Statistical Education. In view of the observed aspects, we have developed an educational product that consists of teaching support material for the teacher to plan his classes.
