The purpose of this study was to explore thoughts and directions for improvement on multicultural education for early childhood teachers through interviews with teachers who had been teaching young children from multicultural families. To this end, in-depth interviews were conducted with 10 classroom teachers who were currently teaching young children from multicultural families in kindergartens or childcare centers and had experience in teaching young children both from foreign families and from international marriage families within three years. The collected data were analyzed using the spiral data analysis method proposed by Creswell and Poth (2018/2021). The results were as follows. First, the teachers' thoughts on multicultural education for early childhood teachers were 'education not provided to pre-service teachers and childcare teachers' and 'education not helpful even if it exists'. Second, regarding the directions to improve multicultural education for early childhood teachers, the teachers proposed education that helps them ‘reflect on their own thoughts and attitudes’, 'gain necessary multicultural information', 'provide practical support to young children from multicultural families', 'support other children as well', and 'understand parents from diverse cultural backgrounds'. This study is significant in that it suggests the future directions of multicultural education for early childhood teachers through the voices of teachers who have been teaching young children from multicultural families in practice.
