English language learners (ELLs) represent the fastest growing group throughout all levels of schooling in the United States. For example, between the 1990-1991 school year and the 2000-2001 school year, the ELL population grew approximately 105 percent nationally, while the general school population grew only 12 percent (Kindler, 2002). In several states (including Texas, California, New Mexico, Florida, Arizona, North Carolina, and New York), the percentage of ELLs within school districts ranges anywhere between 10 and 50 percent of the school population. In sum, there are over 10 million ELLs in U.S. schools today. According to the U.S. Department of Education, one out of seven students in our nation’s classrooms speaks a language other than English at home. Although many of these students are heritage language learners and are procient in English, many others are recent immigrants with barely a working knowledge of the language let alone a command of academic English. Meeting the needs of such students can be particularly challenging for all teachers given the oen text-dependent nature of content areas. e language of the curriculum is oen abstract and includes complex concepts calling for higher-order thinking skills. Additionally, many ELLs do not have a working knowledge of American culture that can serve as a schema for new learning.
