Although links between knowledge and reading comprehension have been widely documented for decades, recent translational science publications (e.g., teacher journals, books, and podcasts) have increasingly referred to studies using baseball (a sport popular in the USA) as a proxy for knowledge to explain those links, especially within science of…

In this paper, I discuss the inspiration, development, and further refinement of the Knowledge Revision Components framework (KReC; Kendeou & O'Brien, 2014). In KReC, we theorize about the conditions that facilitate knowledge revision during reading, and thus successful learning in the presence of prior, often incorrect knowledge. I discuss…

Knowledge activation and knowledge building are essential for reading comprehension. Yet, how can teachers support students in accessing and applying their existing knowledge and experiences during reading? This article provides six evidence-based principles to consider during literacy instruction, which are drawn from a recent systematic…

Comprehending texts in content areas can be challenging for students with learning disabilities (LD) because they may lack the necessary background and vocabulary knowledge needed to construct meaning from text. As more students with LD are educated in the general education classroom, it is necessary for teachers to implement strategies to…

Lexical coverage, i.e. the extent to which words in a text are known, is considered an important predictor of reading comprehension, with studies suggesting 98% lexical coverage leads to adequate comprehension. However, no studies to date have examined how the various lexical coverage percentages suggested in the literature are reflected by the…

This study investigates how working memory (WM) capacity and L2 linguistic knowledge affect L2 literal and inferential reading comprehension, considering the presence or absence of background knowledge. Eighty upper-intermediate to advanced adult English learners participated, completing tasks to assess WM capacity, background knowledge, L2…

Reading comprehension instruction was identified by the National Reading Panel as an effective instructional practice to improve students' reading comprehension. Teacher professional development (PD) is essential for effective reading comprehension instruction to occur in schools. The aim of this meta-analysis is to examine the extent to which…

The role of knowledge and reading comprehension has seen a recent explosion of attention from researchers, journalists, and policy advocates. Much of this discourse describes knowledge in neutral terms such as knowledge of "the world". That knowledge of the world, however, is woven into the fabric of the gendered world we live in and its…

Reading comprehension is not a skill someone learns and can then apply in different reading contexts. It is one of the most complex activities that readers engage in on a regular basis, and the ability to comprehend is dependent upon a wide range of knowledge and skills. Despite a common view about comprehension, several lines of enquiry have…

Internet users are bombarded with information and need strategies to evaluate its trustworthiness. Expert fact-checkers rely on lateral reading, which involves investigating sources, finding better coverage, and tracing information back to original contexts. This study contrasted college students' preference for and use of lateral reading to…

Background: Young children clearly know quite a bit about the conventions of written language; for instance, 5-year-old children are sensitive to the fact that words tend to include both consonants and vowels, rather than just one or the other. The core theoretical debate lies in whether this understanding of sub-lexical orthographic regularities…

Vocabulary is a prominent contributor to reading comprehension. However, little is known about how students with disabilities with lower vocabulary performance respond to Tier 1 instruction, or how their vocabulary knowledge relates to their content acquisition. To examine the differential impact of Tier 1 instruction for U.S. middle school…

Reading comprehension is among the most challenging and complex skills to teach and research. Doing both well is critical to improving the reading comprehension proficiency of 67% of grade 4 students in U.S. public schools who scored below basic on the 2022 National Assessment of Educational Progress. This Chapter presents Knowledge Acquisition…

With a focus on content-area reading, this study aimed to (a) understand the sources and prevalence of concurrent and specific difficulties in word-level skills, vocabulary, and knowledge among adolescent struggling readers (ASRs) and (b) explore the relations among reading skills, profiles, and reading comprehension. A dual-measure screening…

Grammatical and vocabulary knowledge (i.e., breadth and depth) are widely acknowledged as key predictors of reading comprehension in a second language (L2). However, it remains unclear how different aspects of vocabulary depth may independently contribute to L2 reading comprehension and how learners' proficiency may moderate the relative…
