The book provides a review of scientific research on the learning outcomes of students with limited or no proficiency in English in U.S. schools. Research on students in kindergarten to grade 12 is reviewed. The primary chapters of the book focus on these students' acquisition of oral language skills in English, their development of literacy (reading & writing) skills in English, instructional issues in teaching literacy, and achievement in academic domains (i.e., mathematics, science, and reading). The reviews and analyses of the research are relatively technical with a focus on research quality, design characteristics, and statistical analyses. The book provides a set of summary tables that give details about each study, including full references, characteristics of the students in the research, assessment tools and procedures, and results. A concluding chapter summarizes the major issues discussed and makes recommendations about particular areas that need further research.
This article describes and discusses two case studies of content-based instruction for second language education — foreign/second language immersion for majority language students in Canada and dual language education for minority language students in the U.S. After discussing the rationale for CBI in general, we examine 45 years of research on each program model and provide empirical evidence on a number of important issues, including: students’ proficiency in the two languages used for instruction; non-language academic outcomes; whether age is an important factor in students’ language outcomes; and the relationship between age of first exposure to the second language and outcomes in that language. Two outstanding major issues are discussed at some length; namely, the suitability of these programs for at-risk learners and the need for a coherent model of how best to integrate language and content instruction to maximize second language proficiency without detracting from academic achievement. Suggestions for future directions are provided.
The purpose of this study is to examine how 659 Hispanic students in dual language programs in segregated or predominantly Hispanic/low socio-economic status (SES) schools are performing on standardized tests compared to school and statewide comparison groups. Test results are presented from two separate studies of English language learner and native English-speaking Hispanic students in four schools. Data are consistent in showing that Hispanic students participating in dual language programs in predominantly Hispanic/low SES schools achieve at similar or higher levels compared to their mainstream peers in tests of English. In addition, students achieve above grade level in assessments in Spanish. This study affirms the versatility of the dual language program for this increasingly common educational context.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
