SPENCER ABSTRACT Minority Education in the Urban Midwest: Mexican Immigrants and Mexican Americans in Chicago, 1920-1990 Abstract This dissertation examines the educational history of Mexican-origin residents of Chicago to determine education’s influence on Mexican American ethnic identity formation and to illuminate contemporary socioeconomic and political conditions Mexican Americans confront by seeking points of intersection between identity and education. Taking a broad definition of education to include formal and informal sites of educational production during the twentieth century, I use archival research and oral histories to understand the impact of education and ethnic identity on minority acculturation processes. Mexican Americans provide a special lens to view these processes. They are distinct from African Americans, Asian Americans, and Anglo or European Americans, while also being a heterogeneous population within the United States. Such characteristics problematize broad generalizations of Mexican-origin populations who simultaneously are at any given point immigrants - both legal and otherwise - to the United States; internal migrants within the US; and settled residents throughout the nation. Chicago offers an exceptional case study of Mexican populations given its role as a major Midwestern industrial city in twentieth-century America; and thus challenges scholars’ written history of Mexican Americans, which to date has focused almost exclusively on Southwestern locales.
