At the beginning of April Bulgarian teachers started the second MODULE of the REC trainings “The understanding of the self and of the other in the teaching relationship (social awareness)”. They started to study the MAI – Modello di Articolazione Intersistemica. According to it there are three types of personality – motor-instinctual type; emotional type and cognitive type. The recognition and observation of types personality in teacher training is fundamental, according to M.A.I., to understand students. This can happen only after teachers having identified his/her own type. Understanding and harmony eliminates disunity and is a guarantee of success
