Abstract
The purpose of this article is to describe four correction techniques to improve the written text production: projection of texts in acetate laminate, written and oral observation, revision of defective segments and formation of groups of correctors. The described techniques are inserted in a model of correction based on the interaction author, teacher and text. The studies of Cassany (1996) and Serafini (1993 and 1996), mainly, served as theoretical support and, from the point of view methodological, one is an investigation of descriptive, explanatory and propositivo character.
