Volume de tronco de pirâmide utilizando a rapadura: aplicação de uma sequência de ensino investigativa (SEI)

Abstract

With a view to reduce or minimizing the distance between the content and the student`s social context, this article presents a pedagogical experience with Geometry in High School, anchored in the foundations of ethnomathematics. For this end, an Investigative Teaching Sequence (STI) was applied to teach how to calculate the volume of the pyramid trunk with a rapadura. It is considered that ethnomathematics enable the student to encounter important features of local culture, through questions related to the production of “rapadura” in sugar cane mills. The use of STI enabled scientific investigation by students and placed them in a position of active individuals during the process of developing in the sequence of the activities. So much so that, according to the results of the proposed exercises and the pedagogical development and demonstrated learning of the concepts and applications of the proposed content. Therefore, this work has favored the learning of Mathematical skills and abilities that will contribute to the exercise of citizenship.
