Resolução de problemas como recurso metodológico para o ensino da multiplicação combinatória no 6º ano do ensino fundamental

Abstract

This Critical-Reflective Report is the result of a research carried out with students in the sixth year of elementary school at a public school in the municipality of Pedro Osório, RS. The general objective was to analyze the contributions of the problem solving methodology to the teaching of combinatorial multiplication situations. Having as specific objectives: Plan and experience problem situations involving combinatorial multiplication; Evaluate the learning of natural numbers in the 6th year of Basic Education from the intervention carried out; List the strengths and difficulties of using the problem-solving methodology throughout the intervention. The concepts or theoretical frameworks were the problem solving methodology of George Polya (1967) and the studies of Professor Lourdes de la Rosa Onuchic (1999), the idea of combinatorial multiplication, Brazil (2017). The methodology used was action research, conceptualized by Thiollent (2011), which was developed in a total of five meetings with the class. The main instruments for data collection were initial protocol and final protocol, complemented by document analysis, field diary, photographs and filming. The analysis procedures were the tabulation of two categories; analysis of protocols and analysis of problem solving steps, in accordance with specific objectives. The results point to a significant performance in the final protocol, being verified that the data showed after the intervention a growth in the learning strategies and in the abilities of the mathematics teaching
