With U.S. classrooms increasingly characterized by linguistic diversity, policies mandating teacher training around English learning have proliferated. Recent federal oversight prompted Massachusetts to implement an initiative to endorse its 70,000+ teachers in Sheltered English Immersion (SEI). While policy research has productively emphasized…

This article starts with definitions of bilingualism with a focus on the analysis of bilingual competence. Then the aims and types of bilingual education in developing bilingual competence are introduced with focus on analyses of immersion and content-based instruction. Subsequently, the contextual settings of the study are briefly presented.…

The purpose of this review is to provide a comparison of reading outcomes of the two most popular bilingual programs in the United States: Transitional Bilingual Education and Two-way Bilingual programs. To provide context, we present a theoretical framework and a brief historical perspective on how these programs came to gain popularity. We…

The authors of this chapter review empirical studies that have been conducted in bilingual education to propose a future research agenda that incorporates the most recent evidence on the effectiveness of bilingual programs, advances in neuroscience, and the body of evidence of the benefits of being bilingual and biliterate. They first describe the…

This review of the extant research literature focuses on research about content-based language instruction (CBI) programmes in K-12 foreign/second language education in the USA. The review emphasises studies on one-way language immersion (OWI) and two-way language immersion (TWI) programmes, which are school-based and subject matter-driven. OWI…

This literature review will take a focused look at the three currently accepted theoretical foundations upon which two-way bilingual immersion programs are based. Through an examination of research on identity construction in childhood and adolescence, particularly as seen through a critical pedagogical lens, it proposes that there exists a fourth…

Critiques two theories dominating bilingual education. The facilitation hypothesis predicts long-term advantage for bilingual education over all-English instruction. The time-on-task hypothesis predicts that all-English instruction is superior to bilingual education in teaching English. Argues that bilingual programs may facilitate English…

This article compares previous language gain studies in foreign languages with new data on language gain in the instructed second language acquisition of Russian. The acquisition of listening, reading, speaking, and writing proficiency shows a significant correlation not only with hours of classroom instruction in immersion and nonimmersion…

This study attempts to do the following things: (1) to identify values and assumptions as they influence research on bilingual education; (2) to identify and delineate the major theories employed in explaining and predicting phenomena in bilingual education; and (3) to explore alternative explanations of identical phenomena, and to show that…

In dual immersion classrooms, students from different language backgrounds are immersed in the minority language for large portions of the school day with the expectation that they will become equally proficient in their first language (L1) and in their second language (L2). Research on dual immersion indicates that students reach above-average…

This article examines the primary assumption underlying the recent passage of propositions aimed at meeting the need of English language learners (ELLs). The assumption is that English language learners normally need only one year of intensive structured English immersion to learn English well enough to be academically successful in an all-English…

Critiques the Ramirez et al. study of bilingual programs for its serious research flaws. Calls into question the findings of no consistent difference in the achievement of language-minority children regardless of how much Spanish or English is used in instruction. Proposes a reanalysis of the Ramirez data. (KS)

Reviews the reported findings and implications of the Ramirez et al. study. Examines the validity of the operational definitions of the program types and the degree of implementation of the models. Discusses the seven major findings of the study, and some possibly misleading conclusions. (KS)

The final report of the Center for Language Education and Research (CLEAR) lists the various computer searches that have been compiled from information in the CLEAR 655-item database, and categorizes the materials within the database on the basis of educational level, type of material (audiovisual, text, supplementary, workbook, curriculum), and…

Currently, there is no overall strategy for comprehensively addressing the academic needs of English Language Learners (ELLs). Their right to equal opportunities to participate and learn has been recognized by federal law. There is limited evidence regarding bilingual education and effective strategies for educating ELLs. Research indicates that 1…
