We are living through a truly incredible historical epoch: according to futurist Ray Kurtzwail we are living through an exponential epoch because of the speed of the change we are experiencing, not only technological. This historical epoch requires the school, in order to be a true ‘teacher of Life’, to rethink the knowledge it transmits. Among the fundamental knowledge of our culture, over the last 30 years, alongside the classic technical knowledge (hard skills), the so-called soft skills or transversal skills have made more and more room for themselves: skills linked to self-awareness, communication, relationships, etc., the importance of which we are increasingly realising, in every context of life. Teaching children the skills that will accompany them into this future is an exciting and complex challenge. The SPIRIT project was created with the aim of helping teachers, school leaders and researchers meet this challenge by offering an innovative model for teaching soft skills in primary schools, namely between K1 and K4 level . This handbook, the result of a collaboration between some of Europe’s leading organisations involved in education and research – Patrizio Paoletti Foundation (Italy), Erasmushogeschool Brussel (Belgium), Sapientia Hungarian University of Transylvania (Romania), Magyar Digitális Oktatásért Egyesület (Hungary), VitaComm Education (Cyprus) and Thinking Skills Development Research Group (ELTE TOK) as the associate partner of MDOE – is a practical and theoretical guide to addressing this educational transformation.
