Pensamento algébrico: um estudo sobre seu desenvolvimento no 7º ano do ensino fundamental

Abstract

In order to investigate how algebraic thinking can be developed in the 7th year of elementary school, we carried out a qualitative interview. As methodological procedures for data collection we used the structured interview, document analysis and bibliographic survey. The research subjects were 3 teachers from the 7th year of Elementary School. From the data, we verified a mismatch between the indications in the Common National Curriculum Base (BNCC), the importance that knowledge in algebra exerts in the individual's life and the insufficiency of the teaching process for this content, based on the teachers' speeches. Of the 2 books analyzed, 1 approaches algebra according to the BNCC indications, while the other deviates from them. So, it is necessary to reflect on this teaching and seek approaches so that the introduction to algebraic fundamentals can develop in students a truly algebraic thought.
