In this article, we propose a computer device based on text linguistics and intended to help the teachers training process. This device is addressed to the future FFL teachers in Colombian higher education programs. This project emerged from the need to support the teaching of linguistic notions that the future teachers should transmit to their learners. Our system is based on NLP technology for the conception of the activities, thanks to an annotated corpus based on text linguistics notions. This environment could be used in the classroom as well as for distance learning.
