O que é um texto? À primeira vista, esta pergunta pode parecer curiosa para alguns. Afinal de contas, aqui nós nos preocupamos com livros didáticos de Matemática, e isso deixa parecer que uma pessoa sabe o que é um texto matemático em um livro didático. Mas, mesmo sendo o mais importante “instrumento” do ensino na matemática como nas outras disciplinas, o livro parece um desconhecido. Poucos livros didáticos são configurados de acordo com normas cientificas. Os maiores problemas resultam do fato que quase ninguém percebe que precisamos de tipos diferentes de textos para tarefas variadas e que mesmo assim o texto não pode nem substituir o diálogo vivo nem ser excluído ou ignorado do ensino, pois os alunos precisam tanto da comunicação viva como da oportunidade de refletir individualmente sobre o conhecimento.
What is a Text? (Part 1)
Abstract
What is a text? At first glance, this question may seem curious to some. After all, we are concerned with mathematics textbooks for school here, and it would seem that one knows what a text in a mathematical textbook is. But even though textbooks remain to be the most important “instruments” of teaching few of them seem designed by scientific insights or standards. The greatest problems result from the ignorance that different types of goals require different types of texts. Texts could neither substitute personal communication nor could they be excluded from classrooms. The students need as much the living example of knowledge, as they must have opportunity of constructive rumination on their own, individually. Keywords: Text semiotics. Mathematical education. The concept of complementarity.
