Resumo
Avaliações externas mostram que os alunos brasileiros apresentam dificuldades para a aprendizagem matemática e apontam que a atuação docente é uma das variáveis que potencializam o fracasso escolar. Neste contexto, realizamos esta pesquisa de cunho teórico-bibliográfico e documental, que buscou estudar a “Teoria da Metodologia da Mediação Dialética (M.M.D.)” (ARNONI, 2018), em que a contradição é inerente à mediação, na qual, por meio da linguagem, veicula o conceito educativo ensinado entre professor e aluno, dialetizando-o via etapas metodológicas da M.M.D., promovendo a aprendizagem conceitual do aluno. Daí o questionamento: a linguagem do livro didático de Matemática, que oficialmente determina o modelo de aula na educação escolar, promove o estabelecimento da mediação dialética entre o professor e os alunos? Optamos pela análise da linguagem gráfica, cuja função é a de facilitar a compreensão do conceito pelo aluno, sendo utilizada para complementar o texto verbal. Com relação aos resultados da pesquisa, tornaram-se evidentes as limitações enfrentadas pelo autor: por um lado, o fato de ele desconhecer o conhecimento matemático de seus usuários – professor e aluno –, o que dificulta ou inviabiliza a compreensão do que está proposto; e, por outro lado, o fato de ele não apresentar o conceito matemático no manual do professor, em especial, nos primeiros anos do ensino básico, cuja formação inicial é pela Pedagogia, que não tem a obrigatoriedade de ensinar os conceitos científicos das áreas de conhecimento que compõem a grade curricular do ensino básico. É evidente, também, a dificuldade de ilustrar adequadamente a linguagem científica do conceito matemático, limitando as possibilidades de exploração de conceitos. Na perspectiva da mediação dialética, o livro didático oficialmente retira do professor a possibilidade de ele conscientemente planejar, desenvolver e avaliar sua atividade educativa.
External evaluations show that Brazilian students present difficulties for mathematical learning and indicate that teaching performance is one of the variables that potentiate school failure. In this context, we conducted this theoretical-bibliographic and documentary research, which aimed to study the "Theory of Methodology of Dialectical Mediation (M.M.D.)" (ARNONI, 2018), in which contradiction is inherent to mediation, in which, through language, conveys the educational concept taught between teacher and student, dialecting it via methodological stages of the M.M.D., promoting the conceptual learning of the student. Hence the questioning: does the language of the Mathematics textbook, which officially determines the lesson model in school education, promote the establishment of dialectical mediation between teacher and students? We opted for the analysis of the graphic language, whose function is to facilitate the student's understanding of the concept, being used to complement the verbal text. With respect to the results of the research, became evident the limitations faced by the author: on the one hand, the fact that he does not know the mathematical knowledge of its users – teachers and students – which makes it difficult or impossible to understand what is proposed; and, on the other hand, the fact that he does not present the mathematical concept in the teacher's manual, especially in the first years of elementary education, whose initial formation is by Pedagogy, which does not have the obligation to teach the scientific concepts of the areas of knowledge that make up the curriculum grid of elementary education. It is evident, also, the difficulty of adequately illustrating the scientific language of the mathematical concept, limiting the possibilities of exploring concepts. In the perspective of dialectical mediation, the textbook officially removes from the teacher the possibility of him consciously planning, developing and evaluating his educational activity.
