 There is currently no research indicating that one method is preferable to another, but some research indicates that students who spend more time in the partner language do better in that language (Howard, Christian, & Genesee, 2003; Lindholm-Leary, 2001; Lindholm-Leary & Howard, in press) and that language minority students (in the US, those whose native language is not English) do better academically when their native language is supported and developed (Thomas & Collier, 1997; 2002).Some schools like Arizona Language Preparatory, in Phoenix, Arizona, and Alicia R. Chacon Elementary School, in El Paso, Texas, include a third language for a full day or a small portion of the day at all grade levels.Arizona Language Preparatory offers two full days of Mandarin Chinese, two full days of Spanish, and one day of English.
