The conceptual maps has become a great element of potentiality for the higher education, as they allow the teacher refine his expert knowledge and to assure that, this one can be transferable more deeper of his own context, which is more comprehensive for the student. In that way the student can ameliorate his learning process and mainly to establish significant relations between the concepts he is learning. In that document presented here, we describe the teachers experience of the University of Granada that these ones has used the conceptual maps as an element of teaching innovation, and the impact in the learning processes among the students. The professors implicated in that project, have used the conceptual maps as a didactic tool, with students of the specialty of Teacher Education, Pedagogy, and Speech Therapy, that have used those ones as an element of reflection, within the framework of a based evaluation of electronics portfolios. Posteriori, when finishing the project, a questionnaire has been tasted over more than 200 students (the total number of the students who have participated was 250), in order to measure the satisfactory clay of the impact in his learning process of the maps use.
