Estratégias mobilizadas na resolução de problemas matemáticos de divisão por alunos da sala de articulação da 2ª fase do 2º ciclo do ensino fundamental de uma escola estadual de Várzea Grande-MT

Abstract

This paper deals with a Master thesis aimed to investigate which strategies students of Stage 2nd level of the 2nd cycle (5th year of elementary school for students of nine years) attending the resource room of a state school in the count of Várzea Grande, in Mato Grosso, how they manage the Solve Problem Division. The strategy is defined in this dissertation, according Palhares (2004), as a set of techniques to be mastered by solvers helps the student to solve the problem or progress towards finding a solution. This research was designed with the following problem: What strategies students from Stage 2nd of the 2nd cycle (5th year of elementary school for students of nine years) attending the resource room of a State School of Várzea Grande, Mato Grosso, how they manage the Mathematical Problem Divison? Considering the nature of this research, the research methodology adopted was a qualitative approach and is configured in a case study, in which we relied on the authors Fiorentini; Lorenzato (2012); Yin (2010); Bogdan; Biklen (1994) and Merriam (1998). The research was developed in three stages: at first we did a survey of Brazilian research discussing the Solve Problem Division, with the aim of knowing what the authors say about this subject. Thus, the theoretical basis for problem solving is grounded by Onuchic (1999, 2011), Onuchic; Allevato (2009) and Sánchez Huete; Fernandez Bravo (2006), among others. Regarding the definition of strategy in solving problems, we use the definitions of Huete Sánchez; Fernandez Bravo (2006) and Palhares (2004). Through the theoretical framework mentioned subsequently, applied a pilot study aiming to assess the methodology of data collection. The third stage of our investigation it was established with students from Stage 2 of the 2nd cycle ( 5th year of elementary school ) attending the living joint in a state school in the count of Várzea Grande- MT. The strategies deployed by students were identified by: design; long division algorithm with key; division algorithm with short key; algorithm of multiplication; addition and subtraction algorithm. As a result, the students of the resource room have many difficulties with operations, especially with the division, They fail to identify problems in mathematical operations, which explains the fact that some students are beginning literacy and therefore make attempts, trying to hit what operation should be used in the resolution.
