What is the science of reading? The Reading League, in their document "Science of Reading: Defining Guide" (TRL, 2022), proposes that "The science of reading is a vast, interdisciplinary body of scientifically-based* research about reading and issues related to reading and writing." (p. 11.) The asterisk is carrying a lot of…

The science of reading should be informed by an evolving evidence base built upon the scientific method. Decades of basic research and randomized controlled trials of interventions and instructional routines have formed a substantial evidence base to guide best practices in reading instruction, reading intervention, and the early identification of…

Based on 52 studies with samples mostly from English-speaking countries, the current study used Bayesian network meta-analysis to investigate the intervention effectiveness of different reading comprehension strategy combinations on reading comprehension among students with reading difficulties in 3rd through 12th grade. We focused on commonly…

Can the science of reading contribute to improving educational practices, allowing more students to become skilled readers? Much has been learned about the behavioral and brain bases of reading, how students learn to read, and factors that contribute to low literacy. The potential to use research findings to improve literacy outcomes is…

This paper examines the genetic ("nature") and environmental ("nurture") influences on why students vary in their reading skills. We review core findings from the field of modern behavioral genetics, a discipline that studies the interplay of genetic and environmental influences, on reading science. Additionally, we provide an…

This article provides a commentary within the special issue, Integration: The Keystone of Comprehension. According to most contemporary frameworks, a driving force in comprehension is the reader's ability to generate the links among the words and sentences (ideas) in the texts and between the ideas in the text and what the readers already know. As…

We are pleased to contribute to this inaugural issue of The Reading League Journal. The journal's goal is to share information about linking reading science to educational practice. The need is great: literacy levels in the US are shockingly low; a very large percentage of children and adults have only basic reading skills, as indicated by every…

In this meta-analysis of 45 studies involving students in grades 2-12, the authors present evidence on the effects of text structure instruction on the expository reading comprehension of students. The meta-analysis was deigned to answer two sets of questions. The first set of questions examined the effectiveness of text structure instruction on…

Reading comprehension is multidimensional and complex. The persistent challenges children, adolescents, and even adults face with reading comprehension call for concerted efforts to develop assessments that help identify sources of difficulties and to design instructional approaches to prevent or ameliorate these difficulties. Doing so requires…

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…
