RESUMO

Teaching and learning Integral considered basic in the field of Mathematics Education courses, for many times it has focused on a traditional methodological practice based on: definitions, theorems, properties, examples and tests. That methodology has been contributing to a very high rate of abandonment and failure. In teaching this subject, even if we have new technologies used as didactic tools, the textbook is still very important. In this paper, we have chosen Integral to analyze how two chosen textbooks treat this content, based on the Registers of Semiotic Representation by Raymond Duval. It is a qualitative analysis, based on a careful exam of two selected works. We chose those books used in universities nowadays, which have different approaches and readers. The book is a textbook which brings a lot of registers of representation. The analysis allows a deeper study of textbooks, showing future teachers and students that the books have great information and if we know how to use them they can be a valuable tool for the learning process. We tried to show several registers used by authors, the treatments and conversions between registers, which are very important to knowledge acquisition, according to Duvals theory. We look back to the registers used when presenting conceptions, examples and tests, through a more careful analysis. The results show that books can be better studied in a way the student gets a wide comprehension, through conversions, with graphic displays of concepts in a situation of context and motivation both for students and teachers
