Based on research from multiple disciplines, The Great Diversity Dividedescribes the presence and growth of diversity in the United States from its earliest years to the present. The author describes the evolution of the concept of pluralism from a philosophical term to a concept used in many disciplines and with global significance. Rather than assuming that diversity is a benefit, Koppelman investigates the ways in which diversity is actualy experienced and debated across critical sectors of social experience, including immigration, affirmative action, education, and national identity, among others. Koppelman takes the sometimes complicated arguments for and against diversity in school and in society and lays out the benefits with great clarity and simplicity making this book accessible to a large audience.
