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…

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…

The authors examined the impact of 2 subsequent, longitudinal interdisciplinary interventions for 58 Hispanic English language learners (ELLs): (a) Grade 5 science with English language/reading embedded (i.e., science intervention) and (b) K-3 English language/reading with science embedded (i.e., language/reading intervention). Results revealed…

This study investigated the effects of Promoting Adolescent Comprehension Through Text (PACT), a content knowledge and comprehension treatment for English learner and non--English learner students with disabilities who were provided instruction in general education social studies classrooms. Eighth-grade students with disabilities in the treatment…

This paper describes the theoretical framework, as well as the development and testing of the intervention, Comprehension Tools for Teachers (CTT), which is composed of eight component interventions targeting malleable language and reading comprehension skills that emerging research indicates contribute to proficient reading for understanding for…

We tested the effects of teaching reading skills through U.S. History content for 38 eighth-grade poor readers whose reading ability ranged from 2nd to 4th grade levels. Half of the students received special education services and half of the students were English Language Learners. Students were taught to decode multisyllabic words, learn…

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…

This experimental/comparison study of secondary-level, small-group instruction included 318 first- and second-grade students (170 ELL and 148 English-only) from six elementary schools. All schools served high numbers of ELL students with varying school SES in urban and suburban communities. Experimental schools implemented a three-tier model of…

This study provided 5 weeks of direct strategy instruction about narrative elements and relations in 4 first-grade classrooms (n = 83), all with materials that made minimal decoding demands on children's reading. Two comparison classrooms (n = 40) received comparable instruction on language development and poetry. A battery of assessments given at…

This study of 67 intermediate grade students with reading difficulties found that students in a peer-mediated sustained reading condition performed better than peer-mediated repeated reading students and control students receiving typical reading instruction, on fluency but not on comprehension. No effect for the level of text difficulty was…

Attempting to increase reading engagement, a collaborative team implemented a year-long integration of reading/language arts and science instruction known as Concept-Oriented Reading Instruction (CORI). Compared to traditionally organized instruction, the CORI context increased strategy use, conceptual learning, and text comprehension more than…
