This study reports the effects of a distributed professional development model emphasizing reading comprehension and vocabulary practices in social studies on the content knowledge, vocabulary, and reading comprehension outcomes of upper elementary students identified as English learners (ELs). Schools were randomly assigned to one of three…

The purpose of this study was to understand the impact, implementation and costs associated with a one-semester elective lab course in 9th grade, Accelerating Literacy for Adolescents (ALFA) Lab, which seeks to improve students' reading achievement, particularly for those from economically disadvantaged communities.

This study evaluated the feasibility of the Knowledge, Language, and Inquiry (K.L.I.) intervention, designed to support Grades 3-5 multilingual students classified as English learners (ML-ELs) in building content knowledge, language skills, and reading comprehension through inquiry-based small-group instruction. Feasibility was examined across…

This study examined the differential effects of Strategies for Reading Informational Text and Vocabulary Effectively (STRIVE) on the vocabulary, reading comprehension, and content learning among 4,757 fourth-grade students with and without disabilities. Schools were assigned to one of three conditions: researcher-supported professional development…

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program designed to develop upper-elementary students' vocabulary skills in order to improve reading comprehension. The study used a true, group-randomized, experimental design, which randomly assigned 46 4th grade classrooms (n=1324 students) from 12 districts…

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program to improve elementary students' vocabulary skills and reading comprehension. The study used a multi-site cluster randomized, experimental design, which randomly assigned 92 4th grade classrooms (n=2558 students) from two cohorts to a treatment or control…

The purpose of this feasibility study was to inform the development of an intervention to support reading and self-regulation for students with significant reading difficulties and disabilities (RDs), including dyslexia. Participants were 21 special educators, dyslexia specialists, and reading interventionists and 48 students in Grades 2 to 4.…

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 = 2082; n = 1469 from a home where English is not the primary language), many demonstrating low achievement, enrolled in 14 urban middle schools. The 20-week…
