Literacy is a gateway to education, and yet universal literacy remains an aspiration rather than a reality. The science of reading has, however, made significant progress in understanding the key factors that impact development. Five relevant factors can be identified. The first factor is the developmental focus of models. Here the richness and dynamic nature of development is central. Models must clearly explain change and phenomena such as bi- and multilingualism. A second factor concerns bioecological influences on development. Stronger models include understandings of the complexity of gene–environment interactions in development. A third pertinent factor concerns the precise nature of the learning task facing the beginner reader, and in particular the influence of distinct orthographies. A fourth factor concerns the coherent exposition of the cognitive processes involved in “word-level” and “text-level” reading processes. Finally, contextual effects on literacy are profound. Historical and politicoeconomic forces are often linked to wide country- and region-based differences in literacy. A detailed treatment of what is known about effective interventions for struggling readers can be built on the basis of this theorizing. Here, evidence from meta-analysis suggests that both the word-level decoding and text-level comprehension aspects of reading development can be measurably improved through evidence-based interventions. For word-level interventions studies focusing on phonics currently furnish the most secure evidence of impact. For text-level comprehension, interventions focusing on oral language development and text-based meta-cognitive strategy appear the most efficacious. Measure of treatment effects for such interventions show modest but reliable impacts on development and form the basis of ongoing efforts to optimize interventions.

Adequate reading skills are necessary for college and career readiness and success in the work force, but many students do not have sufficient reading skills. The 2019 National Assessment of Educational Progress demonstrated that fourth- and eighth-grade students had made little to no progress in reading since the previous report in 2017. Elementary level students often receive dedicated English language arts instruction during the day, but this is not always true for secondary level students . One way that educators can support students across the grade levels is by providing evidence-based reading instruction within content areas (i.e., science and social studies instruction). Researchers have investigated ways for teachers to provide high-quality content area reading instruction to support the reading comprehension and content acquisition of students in general education settings. Previous research suggests that paraphrasing and text structure instruction support readers’ identification of key ideas and the integration of those ideas across paragraphs and passages when reading content area texts. These practices align with reading comprehension theory in support of conscious text processing while reading. Teaching readers to generate main ideas during reading may improve the reading outcomes and content acquisition outcomes not only for typical readers but also for struggling readers and those identified for special education. Educators’ implementation of such practices within science and social studies instruction may improve students’ reading performance and content learning across grade levels.
