Development levels of this attribute depend on the teacher’s mediation in the process of learning. Creativity can be a challenge for most teachers, since they are unaware of its importance and unwittingly they inhibit by teaching methods that are not aimed at instigating the potential of students. Thus, this article aims to highlight the importance of teacher training for the development of gifted creativity. In conclusion, the mediation of teachers makes the difference in gifted education. As Vygotsky explains, it is precisely through the mediation that it is possible to develop the creative potential.
