Dificuldades apresentadas por alunos do 9° ano do ensino fundamental na resolução de problemas envolvendo equações algébricas do 1° grau

Abstract

The present research analyzed the difficulties presented by students of the 9th grade of Elementary School in solving problems involving algebraic equations of the 1st grade. To support our research, we supported the studies by Shulte (1995) and Pinto (2009) regarding the analysis of errors in algebra; Ponte, Branco e Matos (2000), Nasser (2014), BNCC (2018) and PCN (1998) regarding the teaching of algebra. The research was carried out in a private school in the city of João Pessoa-PB, and had the participation of 18 students. Data were collected through a questionnaire and a written test and analyzed qualitatively. The results showed that the students had difficulties in interpreting the statement, in representing the equation in mathematical language and in applying the necessary mathematical operations to solve the problems. It was also found that many students tend to memorize formulas instead of understanding the mathematical concepts involved in the problems. After completing the questionnaire and the test, a deficit in algebraic interpretation was found, most students who were not so familiar with the letters (unknowns) in Mathematics, believing that Mathematics would be a science that would only be summarized in numerical operations.
