Análise de erros sobre a operação de potenciação na passagem da linguagem natural para a linguagem matemática

Abstract

The objective of this study is to analyze the errors made by 9th grade elementary school students when transposing natural language into mathematical language regarding the operation of exponentiation. To this end, we used an adaptation of the data collection instrument by Jesus (2016), originally applied to 9th grade elementary school students. However, we used only the first question of the instrument, which aims to verify whether students know how to transpose natural language into mathematical language. Although Jesus (2016) himself did not establish the appropriate categories in his work, this task was our responsibility. It is important to highlight that the subjects of this study were 47 9th grade elementary school students from a public school in the city of Sanharó/PE. The first inference from the results collected and compared is the enormous difficulty of both groups in mastering the content of exponentiation, even though they are in the 9th grade and this content has been covered in at least three previous grades. We observed the extreme difficulty of the students in transposing information from natural language into mathematical language.
