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 experimental study examined the efficacy of a multicomponent reading intervention compared to a business-as-usual comparison condition on the reading comprehension and content area vocabulary outcomes of adolescent students with low reading comprehension. We randomly assigned 9th-grade students with low reading comprehension to a…

A 2-year, randomized control trial with 9th to 10th grade students with significant reading problems was provided for 50 minutes a day in small groups. Comparison students were provided an elective class and treatment students the reading intervention. Students were identified as demonstrating reading difficulties through failure on their state…

Achieve3000 publishes a number of online literacy programs that differentiate lessons and activities based on student performance. Magnolia Consulting--an independent, third party evaluation firm--assessed Achieve3000 Solutions' impact on student learning during the 2014-15 school year. The researchers used a randomized control trial, where…

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 aimed to determine the efficacy of a content knowledge and reading comprehension treatment implemented by 8th-grade social studies teachers over the course of 1 school year. We randomly assigned 8th-grade students with reading difficulties to the intervention treatment condition (n = 45) or the business-as-usual comparison condition…

This experimental study examined the effectiveness of a text-based reading and vocabulary intervention with self-regulatory supports for 4th graders with low reading comprehension. Students with standard scores on the Gates MacGinitie Reading Test between 1.0 standard deviation (SD) and 0.5 SD below the normative sample were included (N=44) and…

This study followed a cohort of students from Grade 1 to Grade 11 in one struggling school district that had Reading Recovery (RR) in the Grade 1. The RR program is an intervention given only to students in the Grade 1 who are reading below grade level on the Gates-MacGinitie Reading Assessment. The researched district had a high poverty, high…

The purpose of this study was to contribute to and strengthen previous work that examined the long-lasting effects of Reading Recovery in statewide efforts aimed at bolstering early literacy achievement and reducing early learning difficulties. Specifically, the study explored the literacy achievement of Reading Recovery participants whose series…
