A ESTRUTURA INTERNA DO GÊNERO ABSTRACT DE ARTIGO CIENTÍFICO: UM ESTUDO SOBRE A POSSIBILIDADE DE SUBTIPOS DA SEQUÊNCIA DESCRITIVA DE ADAM

The concept of genre has become fundamental, particularly for the purposes of teaching reading and written production. In Brazil, this line of research has presented a common focus: the perspective of intervention in education issues, either immediately or prospectively (MACHADO, 2005). This study focuses on the characterization of genres as teaching tools and aims to analyze the sequential organization of abstracts of scientific articles, as proposed in Machado (1996). The theoreticalphilosophical perspectives which guided the study are mainly Bakhtin’s Enunciation Theory (1992; 1997) and the Socio-Discursive Interactionism (BRONCKART, 2003). Based on Adam’s concept of sequence, Machado poses a hypothesis according to which the sequential organization of texts belonging to the critical review genre (which includes articles’ abstracts) would be organized by descriptive sequences, as subtypes of Adam’s Descriptive Sequence. Thus, a number of abstracts were here selected and analyzed in an attempt to identify, in their sequential organization, such subtypes of sequences suggested. The analysis showed that the characterization of these texts’ internal structure fundamentally depends on the acknowledgment of the genre to which they belong. This perception, which recognizes these language actions (texts) as abstracts of scientific articles – texts approximately 300 words-long, published in journals, immediately previous to their articles – generates expectations regarding their internal structure and, only then, it is possible to realize them as texts organized into the subtype: Text-Descriptive Sequence
