Mentor 2.0 aims to support a paradigm shift, where teachers are - first and foremost - mentors to their students and not just transmitters of knowledge. After 6 years of Polish MENTOR pedagogy in the offline environment, Mentor 2.0 will develop, test and implement a conceptual framework and an innovative digital platform to enhance mentoring qualities among primary and secondary school teachers. The 2019 Council Resolution on the further development of the European Education Area stresses the importance of supporting the development of competent, motivated and highly qualified teachers. The coronavirus pandemic has further tested the well-being of students and teachers. Mentor 2.0 will address such major challenges of European education as a) the lack of teacher appreciation, b) the lack of digital skills in the formal educational environment that does not follow the digital transformation of societies and economies, c) the increased drop-out rates across the EU - especially during the coronavirus pandemic.
