Implementation fidelity is often thought of as a necessary condition to achieve internal validity and as having a relation to student outcomes. This relation is increasingly modeled; we reviewed reading intervention studies for students in pre-K-12 in which measures of implementation fidelity were included in final data analysis. A systematic…

Although writing instruction can positively impact reading for students across grades and levels of literacy, the extent to which these findings generalize to young students with literacy difficulties is unclear due to the dynamic nature of reading-writing relations. The purpose of this meta-analysis was to examine the effects of writing…

Equipping elementary (i.e., grades K-5) teachers with adequate content and pedagogical knowledge to promote effective reading instruction based on the science of reading is a crucial piece of the reading education puzzle. We reviewed 20 empirical studies to examine the impact of teacher preparation and training programs on elementary teachers'…

We systematically examine the existing evidence and compute meta-analytic averages for the effects of scaled-up, publicly funded pre-kindergarten (pre-K) programmes in the United States on student mathematics and reading achievement. The analysis is restricted to experimental and quasi-experimental research designs with the highest internal…

Tutoring--defined here as one-on-one or small-group instructional programming by teachers, paraprofessionals, volunteers, or parents--is one of the most versatile and potentially transformative educational tools in use today. Within the past decade, dozens of preK-12 tutoring experiments have been conducted, varying widely in their approach,…

In this study the effects of the use of digital student monitoring tools for teachers (DMTs) on student achievement (primary and secondary schools, mathematics, reading, and language) were investigated through a meta-analysis (n = 14). The studies were also coded for feedback and intervention features, which resulted in three groups of…

This best-evidence synthesis reviews the past 20 years of rigorous reading intervention research to identify effective programs of instruction for Grade K-3 English Learners (ELs), as well as to determine the average effect of reading instruction on reading outcomes for this population. We identified 10 studies, all of which only included students…

Reading Recovery (RR) is a constructivist reading intervention used to provide tier 3 instruction to struggling readers in the first grade. The program has been previously evaluated and found effective by Evidence for ESSA (John Hopkins University), What Works Clearing House (intervention report institute for education sciences 2013), and in a…

Informed by theories of reading comprehension and prior reviews of reading comprehension intervention, this meta-analysis uniquely contributes to the literature because it describes the relative effects of various approaches to comprehension intervention for struggling readers in Grades 3 through 12. Findings from 64 studies demonstrate…

In many classrooms across the globe, students are expected to comprehend and produce handwritten and computer-generated texts as soon as they start school. As we progress towards digitalisation in education, it has become necessary to understand the effects of writing modality on students' literacy performance and development. The current…

Educators and researchers have been fighting the reading wars for the last century, with battles see-sawing literacy instruction in American schools from phonics to whole language and, most recently, back to phonics again. Over the last decade, 32 states and the District of Columbia have adopted new "science of reading" laws that require…

In this article, we review research on the outcomes of diverse reading programs on the achievement of struggling readers in elementary schools. Sixty-five studies of 51 different programs met rigorous standards. Eighty-three percent were randomized experiments and 17% quasi-experiments. Outcomes were positive for one-to-one tutoring and were…

REL Midwest conducted a systematic review of research on interventions that may improve academic outcomes for Black students. The review entailed a search for studies that provide evidence at Tier I (strong evidence), Tier II (moderate evidence), or Tier III (promising evidence) according to the Every Student Succeeds Act, and explicitly mention…

This systematic review explores the impact of teacher professional development (PD) on student reading achievement. The first part of the literature evaluates all available existing systematic reviews and meta-analyses of PD intervention studies. No quality reviews of PD and reading specifically (distinct from 'attainment') were found. There was a…

In every school district across the country, every year, initiatives are adopted with the goal of improving the literacy performance of young students, and, just as frequently, these initiatives fail or quickly become passing fads. In this article, Rodgers reviews literature related to scaling educational innovations and describes challenges and…
