Resolução de problemas como uma estratégia para o ensino-aprendizagem de logaritmos e função logarítmica

Abstract

This work has as main objective to understand the potential of Problem Solving and its contributions to the construction of knowledge of the concepts of Logarithms and Logarithmic Function. Methodologically, this research was qualitative and was supported by the Romberg-Onuchic Methodological Model. Aiming to achieve this objective, a field research was carried out, developed in 2018. For this, it was elaborated and conducted, at the State College in Full Time (CEPI) - José Salviano Azevedo - located in the city of Santa Helena de Goiás - GO, a Teaching Project divided into three stages: a teaching “on Problem Solving”, “for Problem Solving” and “through Problem Solving”, with the purpose of leading students to develop skills to solve problems, build knowledge of Logarithms and Logarithmic Function and apply your knowledge to solve new problems. For the theoretical foundation on Problem Solving the works were used: Polya (1995), Larson (1987) and Onuchic and Allevato (2011). The survey of evidences was made by the researcher's observation during the application of the teaching project in the field research; for collecting materials produced by students, such as media (audio recordings and videos) and filling out a field diary. The results confirmed that the three teaching approaches to Problem Solving, “about Problem Solving”, “through Problem Solving” and “to Problem Solving”, if worked properly and jointly, can promote the construction of knowledge Logarithms and Logarithmic Function and also other mathematical content.
