摘要:Purpose: to describe the syntactic and linguistic structures of student´s oral and written productions. Methods: the subjects of this research were thirteen students of the six grade of fundamental education of a private school. Each student made two productions: one oral (recorded and transcribed) and another one written, both productions based on two different pictures. These productions were analyzed in order to investigate syntactic and the speech structure. Results: showed that girls’ written productions are longer than boys’ who performance better in an oral way. On oral and written productions, both groups prioritized coordination form. According to the speech structure, most part of the children were level 1 classified, performing poorer than expected for their age group. Conclusion: this result was beneath expected for the school level. This performance can be explained with some hypotheses: these students were in a transition phase; few speech strategies were taught in school; parents and school provide few stimulation during the oral and written language development.
