Although research provides ample evidence of teaching methods that facilitate students' learning of specific word meanings, the potential of instruction to impact students' general vocabulary knowledge has remained an unanswered question. This article reports on a three-year formative experiment that developed, implemented, and tested a long-term,…

This article reports on a formative experiment involving the implementation of long-term multifaceted vocabulary instruction in second-grade Spanish-English dual-immersion classes. The findings indicate that students in the second year of the project showed accelerated growth in English vocabulary knowledge in comparison to the norming sample of a…

We evaluate the direct and inferential mediation (DIME) model for reading comprehension with a sample of struggling readers in Grades 3 to 5 (N = 364) in the context of a large-scale randomized controlled trial (RCT) investigating two theoretically distinct reading interventions (text processing + foundational skills [n = 117] or text processing…

To address the needs of a diverse group of students with reading difficulties, a majority of researchers over the last decade have designed and implemented multicomponent reading interventions (MCRIs) that provide instruction in multiple areas of reading yielding mixed results. The current study evaluates whether students' baseline word reading…

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…

Testing a component model of reading comprehension in a randomized controlled trial, we evaluated the efficacy of 4 interventions that were designed to target components of language and metacognition that predict children's reading comprehension: vocabulary, listening comprehension, comprehension of literate language, academic knowledge, and…

This report presents estimates from a large-scale, multi-district RCT (randomized controlled trial) on the effectiveness of a summer reading program on improving student reading comprehension for economically disadvantaged grade 3 students reading below the 50th percentile nationally. This study focused on the summer between grades 3 and 4 for…

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…

A quasi-experimental pretest/posttest group design was used to determine whether computer-assisted fluency instruction is as effective as print-based, teacher-led fluency instruction in improving fluency, vocabulary, and comprehension skills in third grade students experiencing delayed fluency development. Fifty participants were randomly assigned…

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…

After the 1984-85 evaluation of the Special Needs Project in the North York, Ontario Schools, it was decided to extend the standardized achievement testing for the 1985-86 school year. Because of previous test validity problems, testing was continued under more uniform conditions; practice tests were available and the achievement tests were…

To compare achievement standards of 1977 with those of 1956, three tests were administered in their original form to all third graders in a large school district. Approximately 3500 students in 1956 and 4500 in 1977 were administered the California Achievement Tests, the California Short Form Tests of Mental Maturity, and the Gates Advanced…
