| Title: | Dual Language Programs Intervention Report |
| Description: | This What Works Clearinghouse (WWC) intervention report summarizes the research on dual language programs. Dual language programs can help native English speakers develop proficiency in a second language and English learners develop proficiency in both their native language and English. Typically, in dual language programs, classroom teachers instruct students from an early age and over multiple years in both English and a second language called the partner language. These programs vary widely by partner language, primary language of the student population, and duration. Most of the studies examined do not meet WWC standards. Based on the two studies that meet WWC standards, the WWC found moderate evidence that dual language programs positively impacted student literacy achievement in English compared with instructional programs in English only. The WWC found uncertain effects on science and mathematics achievement. More high-quality research is needed to understand the effects of dual language programs in varied contexts. |
