Early literacy is a key developmental milestone for succeeding in school, yet far too many children in America, particularly the most socially vulnerable, are not meeting this key milestone. For example, NAEP data from 2013 shows that over 80% of Black and Latinx students are below proficient in reading by the end of fourth grade, as compared to…

Aiming to verify the predictive value of oral narrative structure on reading acquisition, we followed 253 children (first and second graders) during an entire school year, assessing oral narratives and reading performances in five sessions. Transcriptions of oral narratives were represented as word-recurrence graphs to measure connectedness…

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…

This cross-lagged study examined the classroom-level associations between the reading performance of first-grade students (N = 537) and observed literacy instruction activities in classrooms (N = 30) in the autumn and spring terms. The multilevel analyses indicated that lower average word reading skills in the classrooms (i.e., there were more…

Understanding factors that influence reading achievement among bilingual children is considerably more complex than it is for monolingual children. Research on dual language development indicates that bilingual children's oral language abilities are often distributed across languages in varied ways, due to heterogeneity of dual language exposure…

Two groups were formed in a randomized, controlled trial: an Experimental group (n = 346), which benefited from specific interventions by trained teachers for a period of two years, and a Control group (n = 1354) with business as usual. For Experimental group in Kindergarten, the interventions were conducted in small groups and focused on…

This study explores the efficacy of core phonics and intervention products by 95 Percent Group, LLC ("One95"), drawing on the relationship between technology, the science of reading, and learning sciences. Researchers analyzed data from 440 K-1 students in Maryland that rolled out One95 over two school years, fall 2020 to spring 2022.…

The purpose of this randomized control trial (RCT) was to examine the impact of one-to-one high-dosage tutoring on reading achievement of kindergarten and first grade students, many at risk of reading failure. This nearly two-year study collected reading assessment data from 185 students, from across 13 classrooms, randomly assigned to either the…

Various factors at the individual and school levels contribute to the impairment of academic achievement. We examined whether academic class composition, measured as average class achievement and class heterogeneity (variance in achievement within class), moderates the associations of inattentiveness and hyperactivity/impulsivity with academic…

Research indicates that the achievement gap in reading between typical and dyslexic readers is already evident in first grade and persists through adolescence. However, it is not known whether this reading gap persists into adult life. In this report we use an epidemiologic sample of 312 children (typical readers = 246; dyslexic readers = 66),…

Background/Context: Both correlational and experimental evidence suggests that having access to books can be a key resource for accelerating the literacy outcomes for children. Results from a 20-year study across 27 nations by Evans, Kelley, Sikora, and Treiman (2010), suggest that children growing up in homes with many books obtain 3 years more…

Although the important role of children's executive function (EF) in their reading development has been well-established, less is known about the extent to which multilingual children's EF components vary and whether the variability in different EF abilities explains multilingual children's English reading achievement. The present study explored…

Arabic is a diglossic language, where two language varieties are used: spoken Arabic (SpA) and standard Arabic (StA). The words may be "identical" (maintaining the same phonological expression in the SpA and StA) or "unique" to StA). This study examined the effect of diglossia on reading according to the lexical distance…

Research has often emphasised that children who experience difficulties in learning to read get poorer in their performance, and the gap between good and poor readers increases over time which describes the well-accepted phenomenon called the Mathew Effect. However, some studies have shown that the Matthew Effect has not been confirmed. In this…

Word is important in Chinese reading. However, when inter-word spaces are inserted into Chinese text, there is no facilitation or disruption to adults' reading. Researchers argued that there was a trade-off between word segmentation facilitation and disruption due to format unfamiliarity. To assess the trade-off hypothesis, in Experiment 1, we…
