As quatro operações matemáticas no ensino fundamental: produzindo significados para as operações básicas utilizando a tecnologia Webquest

Abstract

In this dissertation we highlight our concern with teaching and learning about the four basic operations of mathematics Addition, subtraction, multiplication and division, always very present in our teaching practice. Our main goal was the design, implementation and application of a WebQuest for the development of teaching that would promote understanding of basic problem-solving operations in elementary school. According to the theoretical references used, we seek to build a WebQuest and problem situation activities that include the production of meanings for basic operations activity in a cooperative learning environment, using computer lab and virtual games involving the four operations together with problem solving. The implementation of WebQuest was developed in two phases: the first, focusing on games with basic mathematical operations and the second focused on producing meanings for problem - situation operations. We present the result of the research carried out with a group of students of the 6th grade of Elementary School in a school of the Rio Verde Goiás Municipal School. This study showed that the applied WebQuest contributed to the improvement of the mental calculations of the students that produced meanings for the children. The operations performed in the activities with interpretative problem solving, acquired ease, among them the multiplication and the division, besides establishing conditions for the accomplishment of the addition and subtraction between numerical calculations. We also noticed the students' progress regarding the autonomy present in the observation processes, hypothesis raising, conclusions and justifications elaboration. We conclude by highlighting the relevance of this research in the scope of the teacher's work, related to the construction of an attitude of seeking understanding of the learning processes of its students.
