This paper presents evidence of the effects of dual language immersion (DLI) programs on the academic outcomes of students in elementary grades. Leveraging enrollment lotteries from four cohorts of DLI applicants across 10 oversubscribed programs, analyses estimate the intent-to-treat effect of access to bilingual education on reading and math…

Using data from seven cohorts of language immersion lottery applicants in a large, urban school district, we estimate the causal effects of immersion programs on students' test scores in reading, mathematics, and science and on English learners' (EL) reclassification. We estimate positive intent-to-treat (ITT) effects on reading performance in…

Though it is estimated that about half of the world's population is bilingual, the estimate for the United States is well below 20% (Grosjean, 2010). Amid growing recognition of the need for second language skills to facilitate international commerce and national security and to enhance learning opportunities for non-native speakers of English,…

This quantitative, causal-comparative study examined the possible cause and effect relationship between educational programming, specifically one-way Spanish immersion and traditional English-only, and native English-speaking fifth graders' vocabulary and reading comprehension. Archival data was used to examine students' reading achievement as…

This dissertation was designed to provide a comprehensive data-driven evaluation of a Chinese language Immersion Program (CIP) for the stakeholders. CIP was implemented in 2006 with a goal for students to become proficient in the Chinese language and develop increased cultural awareness while reaching at least the same level of academic…

This evaluation report summarizes the performance of students who participated in two of the bilingual programs offered by the district during the…

Chapter 3: This study investigated the effects of a new, Spanish two-way immersion program on first through third grade students' English and Spanish proficiency. All students were from an urban, high-poverty community in the Midwest that is English dominant, in a predominantly Anglo state. English-speakers in the two-way immersion program score…

Increasing standardized test scores in reading and math is of high importance to the California Department of Education to meet requirements mandated by the No Child Left Behind (NCLB) act of 2001. More research is needed to understand the best ways to improve tests scores to meet concerns of the NCLB act. The purpose of the study was to evaluate…

The purpose of this study was to examine the effect of a supplemental peer-mediated reading program on reading achievement of first graders (N = 76) in a two-way bilingual immersion (TWBI) program. Nearly 80% of students were Hispanic; of these, 24 were identified as English language learners (ELLs). Classrooms were randomly assigned to…

The effectiveness of the Chicago Mastery Learning Reading (CMLR) Program implemented in Ontario's Kettleby Public Schools (KPS) was measured by the students' reading progress and comparisons with the progress of other students in French immersion (FI) and other non-FI programs, including a gifted program. Within six months of CMLR implementation,…
