In this article, we intend to show part of the results obtained in the present author's Master's thesis, defended in 2010, in which the didactic activities of the argumentative texts from the course book series Português: Linguagens, for high school education, were analyzed. The objective is to analyze how this course book teaches the production of written argumentative texts. Dialoguing with the results, we propose a theoreticalmethodological approach to teach argumentative writing, in the dialogic perspective, having as an excerpt the didactic activity Opinion Article (O artigo de opinião) and the perspective of building meanings by the students. Taking into account that, from the analysis, the questions presented in the course book sequence do not allow the student to live the social practices of argumentative writing, the didactic suggestion here proposed tries to link reading and interpretation procedures with the necessary knowledge for the production of argumentative texts, so as to make it possible the study of a language in the totality of the utterance.
