SUMMARY:

This research aimed to analyze the R programming language as a didactic resource for teaching Statistics in high school. The theoretical framework was based on the guidelines of the National Common Core Curriculum (BNCC) for the field of Statistics, as well as studies addressing the teaching of Statistics in basic education and the use of R software as a pedagogical tool. These foundations provided theoretical support for analyzing the collected data. Regarding methodology, we adopted a qualitative and exploratory approach based on Didactic Engineering, as described by Michele Artigue (1996), which consists of four phases: preliminary analysis, conception and a priori analysis, experimentation, and a posteriori analysis. The participants were 12th-grade students from a private school located in Paulista, Pernambuco. Data collection included written records (pre-tests and evaluation questionnaires), video recordings of all proposed activities, and backups of the activities developed by students in the Posit Cloud environment. The sequence of activities was designed based on the results of the pre-test initially administered to the students, research addressing the teaching of statistics (with an emphasis on mean and standard deviation), and the BNCC (Brazilian National Common Core Curriculum). The pre-test results revealed specific difficulties, including performing standard deviation calculations, understanding distinct concepts related to the mean, and correctly applying the algorithm used for its calculation. Based on these findings, we organized the didactic sequence with activities in RStudio. The results of this phase indicate that the students had positive perceptions of using the software, especially regarding data organization and manipulation. They considered the software helpful in performing calculations, such as standard deviation and the mean of a large dataset. However, the students also pointed out a negative aspect: the need to memorize many codes. Finally, overall, the results suggest that using RStudio in basic education can be an effective tool for teaching statistical concepts and programming.
