 For example, an eight-year study of the Navajo/English two-way bilingual program at the Rough Rock Community School in northeastern Arizona confirms that those students who received thorough instruction in their native language as well as the target language encountered more success in school than their peers in English-only programs (McCarty, 2000).Such students too showed progress in both languages in their writing abilities on local and national measures (McCarty, 2000).In addition to quantitative measures of effectiveness, research has further credited the two-way immersion model as creating more unified communities in public schools amongst parents and caregivers since speakers of both majority and minority languages are grouped together in an effort to develop literacy skills in both languages and consequently foster cross-cultural relationships in both cultures (Scanlan, 2009).
