Over the past three decades, many countries in the world have displayed increasing racial, ethnic, linguistic, and cultural diversities. No matter where you go -- be it Singapore, New Zealand, Canada, Austria, South Africa, China or England, for sure you would see and hear it. We face the challenges of educating the diverse student populations, equal distribution of education resources, and the problems of achievement gaps between mainstream students and students from racial and ethnic groups. As this has become a global phenomenon, a conversation at the global level on how these challenges manifest in different countries, or grappled by different education systems under different social contexts will be very meaningful. Hope you would share your stories here with everyone.
