With the help of interviews and workshops, Laura Miettinen reviewed what music teacher educators at Sibelius Academy, University of the Arts Helsinki and the Israeli Levinsky College of Education thought of interculturality and intercultural competence, i.e. attitudes, skills and knowledge that teachers need when facing cultural diversity in their work. The dissertation aims to increase understanding of how cultural diversity is—and could be—approached in music teacher education and how the change towards making music teacher education programs more interculturally competent could be initiated.
