Aprendizagem de geometria no curso de pedagogia: um experimento de ensino sobre a formação dos conceitos de perímetro e área baseado na teoria de V. V. Davydov.

Abstract

The pivotal issue that we sought to clarify was how the organization of the geometry academic curriculum, founded on Davydovs Theory of Developmental Education, could help graduate students of Education formulate the concepts of area and perimeter. Research began with a diagnostic assessment, which revealed a lack ofdomain in students who are beginning the pedagogical program graduation centered on the basic operations of mathematics, specifically focusing on geometry. Beginning with the students shortcomings in the formulation of mathematical concepts, we sought to clarify the following questions: With the teaching of instrumental mathematics based on the theory of Developmental Education,what are the possible effects in the students quality of learning? Could thisteaching foster an environmentof intellectual development in students through learning the basic concepts of geometry, such as perimeter and area? What contradictions involve the practical realization of Developmental Education, in the context of a graduate degree in Pedagogy? What kind of interpretation and evaluation did students use from their learning about perimeter and area, on this alternative for organizing the teaching of mathematics? Therefore, the study aimed to: analyze the contributions of the Davydovs theory of Developmental Education to the organization of geometry and its practical application, in view of the learning of the perimeter and area concepts for students in the first semester of the Pedagogy program. The field study involved a thirty-six-student class in the pedagogy course and a teacher, with whom we developed a formative educational experiment. The investigation consisted of bibliographic and field research. The literature review spanned the periods from 2005 to 2014, focusing on the learning and training of these concepts. Data collection involved questionnaires, reports of the subjects, interviews, and audio and video recordings. The teaching experiment was conducted in eight (8) h(a) for ninety (90) minutes each between February and June 2014. The didactic experiment followed the basic premises of Davydov. In the data analysis, Bogdan & Biklen (1994) guidelines to the categorization and systematization of data were adopted. The data analysis revealed that this studys main contribution was to provide an alternative way of organizing mathematics teaching, considering that the experiment exhibitedthat on average, 85% (eighty five percent) of students demonstrated qualitative changes in the way thinking about the concept of perimeter and 72% (seventy two percent) about the concept of area.
