As aplicações e contribuições da geometria plana na educação de jovens e adultos no ensino fundamental por meio de unidade de aprendizagem

Abstract

The application of learning units in plane geometry brings the teacher a new way of teaching. The students reconstruct knowledge relating the everyday practices and knowledge to mathematics in order to enable meaningful learning. The research was conducted in a private school in the city of Farroupilha-RS with students from a class of adult education (EJA). Two different units of learning related to the content of plane geometry were applied. The first unit consisted of the confection of a graduation T-shirt, which was later used to elaborate clothes for dolls with the scraps of fabric. The second was the construction of the model of a house. In the investigation, data were collected from the students through two questionnaires used in class. Interviews were later conducted with six students in order to check their understanding and prior knowledge concerning the comprehension of the concepts of plane geometry. From the data analysis, it is possible to have a better comprehension of the EJA`s students, that generated qualitative and quantitative data and which were further submitted to a textual discursive analysis. To support this research, three authors were mentioned as theoretical reference. Pedro Demo, who believes in the reconstruction of knowledge through language; Paulo Freire, educator internationally recognized for his literacy method through awareness applied to lower classes; David Ausubel, responsible for the meaningful learning theory. It was concluded that the use of the learning units, combined with the students` knowledge, allowed a meaningful learning and thus having long-life geometric concepts. Furthermore, it was noticed that the teaching of mathematics can be reconstructed at any time, since it comes from the ideas and the interests of the students. The suggestions for teachers who want to work with UA, is to turn a simple class into a memorable moment for the students, changing the empirical knowledge into scientific knowledge.
