This book traces the research on the design implementation and outcomes of a professional
development program for in-service primary and secondary school teachers aimed at enhancing
their understanding of living music traditions in Singapore and how these could be taught in
the 21st century music classroom. It proposes a professional development framework comprising
the areas of Pedagogy Practice and Perspective to guide professional development design. The
book also aims to promote further discussions on adult learning and teaching about teaching
especially with regard to developing self-efficacy to handle different music traditions in a
21st century multi-ethnic society like Singapore.
