The recent influx of Latino immigrants in the Mid-West U.S. has also increased the number of Mexican students in schools. As recent immigrants, one of the challenges Mexican students face besides learning a different language is the construction of new identities in unfamiliar environments. Learning a language involves acquiring another identity in addition to learning a novel vocabulary and a different grammar. Using cricital discourse analysis, I argue that Gee's four aspects of identity though useful when discussing identity in the context of schooling, are limited when dealing with identity in the context of choice of linguistic code. They should be expanded to include linguistic identity when dealing with choice of linguistic code. In addition, schools should create spaces in the classroom for Mexican students to comfortably enact and develop their linguistic identities of Spanish-speakers since the primary language plays an important role in acquiring and developing literacy.
