Summarizes a 4-year longitudinal study of over 2,000 elementary students. Compares three alternative instructional programs for Spanish-speaking, limited-English-proficient (LEP) students: structured English-immersion strategy; early exit bilingual programs; and late-exit bilingual programs. Primary language instruction seems beneficial to LEP…

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…

Based on a literacy interdependence theory, uses findings from the Ramirez et al. study on programs for Spanish-speaking, limited-English-proficient students to refute theories opposing bilingual education. Expresses concern that all three program types in the Ramirez study reflect transmission models of pedagogy in which students have little…

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)

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)

Longitudinal studies from the 1980s suggest that the greater the amount of native language instructional support for language-minority students, combined with balanced second language support, the higher they are able to achieve academically in the second language in each succeeding academic year, in comparison to matched groups being schooled…

Analyzes the political, educational, and technical factors that strongly influenced the Ramirez study of bilingual programs. Enumerates strengths and weaknesses of the study's research methodology, along with implications for decision making in language-minority education. Summarizes defensible conclusions of the study that have not yet been…
