RESUMO:

The teaching of geometry in Brazil is in difficulty, because the influence of Modern Mathematics has caused a process of emptying in the learning of this great area of mathematics, since it is no longer worked with the students and in the opportunities in which this occurs the teachers work very quickly and do not take into account the process of construction of geometric skills. they only seek to present the contents and algebraize them, this ends up not enabling a learning that can make the student think about geometry in a dynamic way and full of possibilities. This abandonment of geometry in our country has caused a drop in the performance of students in the so- called external assessments, where the numbers of results in mathematics have been alarming. In view of the above, the present work seeks to identify: What potentialities does a didactic sequence present for the teaching of triangle similarity, based on theuse of concrete materials structured according to the Articulated Units of Conceptual Reconstruction, aimed at students in the public elementary school system? Structured according to the Articulated Units of Conceptual Reconstruction, aimed at students in the public elementary school system? To answer this question, we will do the following procedures: Obtain information that contributes to the elaboration of the didactic sequence from research in the literature, perception of teachers and students about the teaching of similarity of triangles, especially regarding the difficulties and obstacles in the teaching processes and learning, to make the analysis of textbooks intended for public school students who are the target of this research, to make a study of the content similarity of triangles in the light of mathematical rigor and from these studies, to elaborate activities to compose a didactic sequence that will be applied to students of the 9th year of Elementary School, To evaluate the students' performance in relation to the resolution of questions involving the similarity of triangles after their participation The present sequence was applied to the students of a State Public School in the Metropolitan Region of Belém. After the application of the sequences, the data were analyzed in the light of microgenetic analysis and discourse analysis. From these analyses, it was possible to conclude that there were several signs of learning throughout the process, based on each of the participating groups. Finally, from this dissertation was generated an Educational Product entitled Didactic Sequences for Teaching Similarities of Triangles with manipulable materials, available at the link below.
