We conducted a randomized field trial to test an academic vocabulary intervention designed to bolster the language and literacy skills of linguistically diverse sixth-grade students (N = 2,082; n = 1,469 from a home where English is not the primary language), many demonstrating low achievement, enrolled in 14 urban middle schools. The 20-week…

Vocabulary acquisition is central to language learning, and many instructors believe that technology can facilitate this core activity. While numerous websites and apps offer language-learning activities and games, not all provide evidence that their content and techniques are effective. VocabularySpellingCity (VSC), however, commissioned a study…

This article presents the results of a study testing the efficacy of an instructional model that attends to the science, literacy, and language learning needs of English Learners (ELs) through a curriculum development project. The model is based on the premise that reading, writing, and discourse are better served when these important language…

One in five school-age children in the U.S. speaks a language other than English at home (Zeigler & Camarota, 2014). Roughly half of these emerging bilingual students (Garcia, 2009) are classified as English learners (ELs) when they enter school, meaning they do not meet state or district criteria for English proficiency (NCES, 2015). As the…

This study examines the longer term effectiveness of a standard protocol, Tier 2 supplemental vocabulary intervention for kindergarten English learners, designed to develop root word vocabulary knowledge and reinforce beginning word reading skills. Participating students in the original study ("n" = 93 treatment, 92 control) received 20…

This study reports on the effects of the Pathway Project, a professional development intervention aimed at supporting the academic language development of English Learners (ELs). Using a subset of data collected during a multi-site cluster randomized controlled trial involving nine middle and six high schools in an urban, low-income school…

The increase in language minority students in U.S. schools has drawn attention to instructional models designed to assist these students. It is critical that literacy educators understand the potential of these models for literacy achievement. This study was designed to examine reading achievement of elementary English language learners in…

This article describes a study examining the effects of Sheltered Instruction Observation Protocol (SIOP) model instruction on the academic language performance of middle and high school English language learners. The SIOP model is an approach for teaching content curriculum to students learning through a new language. Teachers employ techniques…

Discontinuities are often found between top-down language education policies and local language policy enactments, as de facto language policymaking results from stakeholders' negotiation and interpretation of policy mandates. Teachers occupy a particular role in the execution of language education policies, as they are the "final…

This monograph showcases professional development projects by school districts and colleges of education that train teachers to work successfully with English learners (ELs) across the nation. The papers presented in this monograph offer real-life examples of successful and innovative practices, including institutionalized mentoring programs, new…

Hulstijn and Laufer (2001) proposed a motivational-cognitive construct of task-induced involvement to account for variation in effectiveness among different vocabulary learning tasks. Building upon their original research, this study consisted of two experiments investigating the involvement load hypothesis in vocabulary learning. Experiment 1…

An experimental study was conducted comparing the effects of dual language, or two-way immersion (TWI) and monolingual English immersion (EI) preschool education programs on children's learning. Three-and four-year old children were randomly assigned by lottery to either a newly established TWI Spanish/English program or a monolingual English…

A tuition-free, vocational, English as a second language (ESL) program offered at a large community college suffers from high attrition as well as student dissatisfaction with curriculum. The purpose of this quasi-experimental, longitudinal study was to assess the effectiveness of a specific ESL curriculum supplement as an intervention to…

This study involves the collaboration of researchers with 24 teachers in a 3-year intervention study aimed at investigating and improving vocabulary knowledge and reading comprehension of fourth and fifth grade students for whom English is a second language. Cross-sectional and longitudinal data were collected on various aspects of vocabulary…
