This study investigated the effectiveness of an intervention designed to support sixth-grade Spanish-speaking English as Additional Language (EAL) learners and their English proficient classmates in acquiring pre-algebra knowledge and skills and associated academic vocabulary. The sample consisted of 88 EAL learners and their 139 English…

Language immersion programs seek to develop multilingual, multiliterate individuals able to engage with academic content. Studies of immersion students' language development provide details regarding language proficiency and accuracy, yet they generally do not address how features of written, academic language, for example, syntactic and lexical…

With this article I explore the relationship between core academic language skills (CALS) -- a construct representing a set of high-utility language skills needed to manage the linguistic features prevalent in academic texts across content areas -- and schooling outcomes. There has long been an understanding that there is a distinction between…

Language borrowing from sources is a phenomenon used by developing writers as they are learning academic language, though there is much to be learned about how younger students borrow from sources. This study explores student writing, from a sample of 166 diverse middle graders, across topics to determine patterns in borrowing from instructional…

Previous research on the development of second language (L2) reading comprehension among adolescents and adults has looked at the relative importance of students' second language (L2) linguistic skills and home language (L1) reading comprehension skills in the development of L2 reading comprehension, with many studies finding a more important role…

The recent results of the Education First English Proficiency Index (EF EPI) showed that the country placed seven spots lower compared to the past ranking. The purpose of this study is to determine the level of competence of students in grammar and academic writing and to find out if a significant relationship existed between the variables. This…

Academic vocabulary is one of the most important skills needed in language learning, but it may be difficult for students whose native language is not English. The purpose of this qualitative study is to investigate how classroom core subject teachers at Middle School 55 (pseudonym) perceive their ability to implement specific instructional model…

The aims of the current project were to: (1) describe average change in the use of academic words across the school year in writing and (2) examine potential predictors of growth in academic word use in response to morphology-focused supplemental instruction. Investigators utilized written expository responses of 824 students in 5th grade before…

The challenges involved in navigating between home, school and academic languages, especially in a low resource context, have been well documented in the literature. Processes and strategies that allow the use of students' "language as resource" have also been suggested by research. In the context of explorations, where students work…

Recently a novel instrument -- the Core Academic Language Instrument (CALS-I) -- aimed at testing a constellation of school-relevant English language skills was developed and validated for use in the United States (Uccelli, Barr, Dobbs, Galloway, Meneses and Sánchez, 2015. Core Academic Language Skills: An expanded operational construct and a…

This study examines the relationship between English language proficiency outcomes and the use of a Computer-Assisted Language Learning (CALL) tool that is designed to strengthen the academic English and oral proficiency skills of young English Learners (ELs). We compare scores on a standardized English language proficiency assessment for 2,034…

This study investigates the concurrent and longitudinal relationships between polysemous word knowledge and reading comprehension among bilingual students (n = 107) followed from seventh to eighth grade. Standardized tests were used to measure decoding skills, broad vocabulary knowledge, and reading comprehension. Data about students' polysemous…

As with all learners, English learners (ELs) require more than basic reading and writing skills to successfully engage with rigorous academic content, progress through school, and be fully prepared for postsecondary education and careers. ELs must be able to access grade-level content while simultaneously developing proficiency and autonomy in…

Using findings from a 4-year research and development effort, we propose an updated model of sheltered instruction for science classrooms that leverages the opportunities provided by the Next Generation Science Standards (NGSS) to better support multilingual learners in middle and high school science. Using data from teacher implementation logs…

The nature of this research study examines the relationship between text-talking and writing skills used by American Sign Language (ASL) and English speakers. When given ample opportunity to text-talk in academic settings, it is likely that students will improve their expressive communication and writing skills. The main research question asks:…
