'E essa é a minha opinião': para o estudo da emergência da escrita argumentativa
In this article, we present an empirical study on early argumentative writing, in opinion texts written by children
of the 2nd and 4th grade (1st cycle of basic education). The analysis of discourse and linguistic properties shows
early skills in written argumentation. These results call into question the Portuguese teaching guidelines, which
only begin providing for the writing of opinion texts in the 5th grade. This study also brings to light the conclusions
of similar studies (Brassart, 1990, Leal & Morais, 2006) and contributes to the characterization of writing
development and linguistic awareness in the initial school years.
