In the season three premiere of the #conversations4citizenship podcast, Prof. Keith Barton and Prof. Li-Ching Ho explain why they treat social and civic education as a single concept in their book, rather than addressing them separately. They also introduce the concept of "critical harmony," which emphasizes the importance of relationships, values diversity, embraces conflict, and seeks balance in power dynamics. Throughout the episode, Keith and Li-Ching discuss the relevance of justice and harmony in various global contexts, acknowledging that interpretations and applications may differ based on geopolitical and geographical factors. They stress the importance of preparing young people to live together justly in a diverse world and highlight the role of education in fostering critical harmony.
