RESUMO

This study is a qualitative research that aims to looked at four pairs of students in the 3rd grade of high school segment of the education of the Education of Young and Adults (EJA) from a public school and the central municipality of Franco da Rocha. These students solved problems four situations-problems, which were guided by the Ethnomathematics Ubiratan D Ambrosio (1975), involving the Calculations labor using the mathematical concepts and Percentage of Rule of Three. Focus our research seeking to answer the following questions: 1) Why do students of the EJA have both interest and curiosity in learning calculations labor? What are those interests? 2) What have previous knowledge that students of EJA need for the resolution of situations-problem involving the calculations labor? 3) What are the difficulties presented by students of the EJA when solve situations-problem involving the calculations labor? 4) What impact caused when the math is presented in a contextualized way to the life of pupils of EJA? We used two instruments for research, the Instrument 1 that identified the labor concepts that the students surveyed had an interest in knowing and learning and Instrument 2 composed of four-problem situations and developed after the Instrument 1. Using us as some elements of the engineering teaching, we seek to build situations that could lead students to an autonomous stance with problem-solving strategies proposed, engaging them and making them actors of the learning process. Both search engines were sufficient to answer the four questions proposed above, and consequently the results were satisfactory, indicating that contextualizing the teaching of rule of three percent and the calculations using labor, the impact on the lives of students is seen so positive, making the learning process more meaningful
