The fundamental significance of literacy achievement cannot be overstated. However, the 2022 National Assessment for Educational Progress (NAEP) divulges alarming findings, with a mere 33 percent of the nation's fourth graders performing at or above proficiency in reading (NAEP, 2022). Exploring the nexus of research-informed pedagogy and practice…

This study examined the heterogeneity of early literacy profiles of English learners and non-English learners. Utilizing a latent profile analysis, the degree to which distinct learner profiles emerged was examined using code-based and language-based measures administered in the beginning of first grade. Participants included 11,803 English…

Reading acquisition in Arabic presents unique challenges, notably due to its complex morphological structure and the diglossic nature of the language. The discrepancy between written (Modern Standard) and spoken Arabic poses significant barriers for learners, particularly in decoding morphologically complex words. This study explored the role of…

High-quality decodable books enhance literacy by providing children with focused practice opportunities to break down sounds they have learned and apply their decoding skills. Just Right Reader (JRR) hired LXD Research to measure its impact during a pilot study in the Spring of 2024 to determine the effect of their decodable books on literacy…

Many second language (L2) students in Sweden struggle with reading in Swedish. There needs to be more research on how L2 students with weak word decoding skills in Swedish could be individually supported. Therefore, the current study examined the impact of a systematic and intensive word decoding intervention in Swedish among individual L2…

Previous studies uncover that vocabulary knowledge may be related to compound structure awareness (the awareness of relational structure embedded in compound words), and they both contribute to reading comprehension. Yet, limited studies have examined the dynamic relationship between vocabulary knowledge and compound structure awareness, or their…

This study investigates the role of diglossic and orthographic features in reading comprehension in Arabic. Specifically, it probes the independent contribution of language, metalinguistic, and decoding skills in the spoken language and in Standard Arabic to reading comprehension in the "abjad" writing system of Arabic. A sample of 112…

The purpose of this longitudinal study is to investigate the association between poor language skills in toddlers and later reading skills. In contrast to earlier research, the present study used an authentic assessment of language skills conducted by staff in early childhood education and care as a tool for early identification. The participants…

We report on a school-based randomized control trial study comparing two morphological interventions with untaught controls: one focusing on direct instruction targeting print morphological decoding (direct decoding condition) and the other on inquiry-focused pedagogy using oral morphological analysis (inquiry-analysis condition). We identified 63…

Purpose: Having a clear understanding of the types and amounts of classroom literacy learning opportunities is important for contextualizing children's early literacy performance. In this study, we examine the content, context, and management of literacy learning opportunities in a large, geographically diverse sample in the United States. We also…

Shifting demographics in K-12 schools have increased Spanish-speaking Multi-Language Learners' (MLLs') enrollment across the United States. While literacy variations between MLLs and proficient English speakers have been studied predominantly with upper elementary students, there remains a need for more exploration among early elementary…

Young children of Color from minoritized communities can co-author decodable stories using phonics skills they have been taught, their lived experiences, and home languages, including nondominant English languages, to develop decoding skills using student-generated decodable readers. While traditional and curricular decodable readers are used…

Background: Learning Progress Assessments (LPA) have been developed to help teachers individualize their curriculum. The use of LPA is facilitated by an increasing number of computerized LPA tools. However, little is known about student factors that influence the effectiveness of computerized LPA. Objectives: In this study, we explored whether a…

Reading comprehension and arithmetic skills are essential abilities for children, particularly at the early career. Examine the link between language proficiency and numeral information process amongst primary school children. This study examines numeral comprehension in 600 Chinese primary second graders with different levels of decoding and…

Hebrew allows the representation of the meaning of a few words in one dense form by using bound morphemes that linearly attach to the word. By manipulating words' density in text, that is, decomposing them into isolated words which changes the length of the text, it was possible to check the impact of density on reading comprehension in novice…
