Aprendizagem da Álgebra - uma análise baseada na Teoria do Ensino Desenvolvimental de Davídov

Abstract

This study is based on the Historic-Cultural Theory, particularly on the Theory of the Developmental Teaching of V. V. Davídov, and it is situated in the field of Didactics, specially in the didactic of Mathematics. The research tried to investigate and understand why some students learn Algebra while others has many difficulties. The objectives were: identify the difficulties and/or facilities of the students in the process of learning Algebra; analyze the data under the perspective of the Theory of the Developmental Teaching; show the contributions of the Theory of the Developmental Teaching to the teaching of Algebra, aiming the overcoming of the difficulties of learning. The qualitative research was a case study in a seventh series class of a public school of Goiânia. The research subjects were the students and the teacher of the class investigated. The instruments of the data collecting were the direct non-participant observation, semi structured interviews, research of documents and an exam applied to the students about a specific subject of Algebra. The results showed that the social cultural dimension of the students, although perceived, do not have been considered in the planning and development of the classes of mathematics; the students do not understand the sense and the meaning of the algebraic language; in the process of teaching, the subjects of the Algebra are not related to the mathematics, neither scientific, nor scholar.
