THE POLYA SEQUENCE APPLIED TO SPACE GEOMETRY TEACHING
Mathematics Teaching. Polya Sequence. Significant Learning.
Encouraged to contribute to the improvement of mathematics teaching in which the teacher needs to practice actions that involve the students in order to provoke interest in the contents and make them active in the construction of knowledge, we develop this work from the classes taught, applying the Sequence of George Polya, described in his book The Art of Solving Problems, to stimulate the resolution of questions involving the calculation of volumes of geometric solids. This sequence suggests that the elaboration of the solution of mathematical problems is organized in four stages: Understanding the problem; Establishment of a plan to solve the problem; Execution of the plan and Retrospect of the resolution, aiming, thus, a significant learning and promoting a heuristic that will be taken beyond the school environment. The classes were taught from the Ausubelian perspective, always trying to identify in the cognitive structure of the students, preexisting relevant concepts in order for the new knowledge to be anchored, promoting student growth and maturation. We also present a chapter on volume of geometric solids with demonstrations of the formulas on their respective volumes based on the Cavaliere Principle. We conclude the work by presenting the development of the classes and the solutions given by the students using the steps of the George Polya Teaching Sequence.
