This paper focuses on the construction of the concept of Textual Linguistic (TL) by mother tongue teachers in the semi-arid region of Bahia. It specifically concentrates on the reformulation strategies of concepts from a scientific text for general public, considered as the base text, in 1) the oral discourse of the teacher trainer in the classroom and 2) the comments made by two training teachers about their students' written texts. In the teacher trainer's discourse, reformulations have an explicative or didactic nature aimed at learning. In the oral comments of the training teachers, concepts are reformulated with the help of terms typically used in the ordinary language, without risks of contradictions or reduction of the basic concepts. Reformulations thus have an appropriative nature since the scientific concepts are reformulated according to the users' way
