The purpose of this study was to investigate Spanish-speaking multilingual learner (MLL) students' long-term academic outcomes after participation in an early childhood education (ECE) program with English instruction. The study included 359 Spanish-speaking MLLs who qualified for Free and Reduced Lunch from Grade 1 to Grade 6. Participants…

The purpose of this study was to examine the differences in the academic growth in mathematics and reading for elementary Spanish-speaking English language learners, in relation to teacher certification and training in teaching English as a second language (ESL). The study was conducted in a Midwestern urban public elementary charter school. A…

Using data from students in Grades 3-8 in school years 2018-2019 (N = 1,871) and 2021-2022 (N = 1,740), we examined the strength of fall math screening using Measures of Academic Progress (MAP) for predicting end-of-year state math assessment performance levels and whether this prediction varied across English language proficiency (ELP). In…

The unprecedented growth of Spanish-English dual language learners (DLLs) in new destination states (e.g., Georgia, Indiana, South Carolina, Tennessee) calls for better understanding of the relation between their bilingual vocabulary skills and English reading achievement. The current study focused on school-age Spanish-English DLLs (N = 60) in…

Many classroom teachers, however, have not had specialized training in providing instruction for ELs. The BELLA (Bridging English Language Learning and Academics) professional…

We examined whether English language proficiency (ELP) related to interim reading and math performance differently when academic assessments were administered to students in either English or Spanish. We also tested these effects with Spanish language proficiency (SLP) as well as jointly with ELP and SLP. Students from a midwestern suburban school…

This manuscript-based dissertation is comprised of three interrelated longitudinal studies on Spanish language growth and deceleration and its impact on English language growth and English reading skills in bilingual children. Chapter 1 introduces the manuscript-based dissertation and provides the background on existing, longitudinal work of dual…

Previous studies about ELs have reported data on active English Learners--defined as those students who have not yet reached proficiency on a state English test--at a specific moment in time. This study, for the first time, analyzed the long-term trajectories of 18,000 CPS students who began kindergarten as ELs and followed their progress all the…
