The implementation of effective dual-language programs

[EN]This research investigates the ways of implementing dual-language programs and the schools’ internal procedures of evaluating them. Previous studies have examined the effectiveness of bilingual programs (Genovesee et al. 2005; Howard et al. 2005; Krashen 2004). However, there is little still known about schools’ procedures that systematize the organizational aspect of such programs. The Mixed Methods Research (MMR) approach was applied in this study to analyze data collected through questionnaires, interviews, and case studies.
