Many children speak language varieties (dialects), such as African American English (AAE) that differ from the language variety typically used in academic settings and in literacy instruction (Mainstream American English, MAE). There has been considerable work suggesting a negative correlation between use of a non-mainstream dialect and lower…

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…

The current research used the Proficient Academic Reader (PAR) framework to explore whether reading strategies, task awareness, and motivation predicted college students' literacy skills over and above foundational skills (e.g., decoding, vocabulary). Specifically, the current research investigated the unique contribution of the PAR constructs to…

This case report describes a decoding intervention that was developed for and implemented with a 15-year-old female with significant word-level reading challenges. The intervention integrated multiple evidence-based approaches to improve decoding, including instruction in (a) phonemes-graphemes (sounds-symbols) that the participant did not know at…

Educational technology is ubiquitous, and educational technology interventions often target literacy. However, there is insufficient information about the effects of these interventions on literacy outcomes in elementary school. Therefore, we conducted a systematic review and meta-analysis of quasi-experimental and experimental studies published…

Childhood Apraxia of Speech (CAS) is a developmental speech sound disorder (SSD) notable for its severity and persistence of speech difficulties. A debate has surfaced historically about the cause of the speech and language deficits observed in the disorder. As children with CAS often present with comorbid language problems (i.e., receptive and…

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…

In many countries, children need to become proficient in both their home language (L1) and an international language, such as English (L2). Governments face tradeoffs in how to prioritize these two objectives. We provide empirical evidence on cross-linguistic transfer between L1 and L2, using the results of two randomized evaluations of Structured…

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…

The current research used the Proficient Academic Reader (PAR) framework to explore whether reading strategies, task awareness, and motivation predicted college students' literacy skills over and above foundational skills (e.g., decoding, vocabulary). Specifically, the current research investigated the unique contribution of the PAR constructs to…

Research Findings: This study examined the extent to which children's development and growth in oral language and literacy skills during the early childhood period predicted writing ability in the primary grades. Participants were 313 children who were tested on a battery of oral language and literacy measures at four time points, beginning during…

This study assessed the direct and indirect effects of Supporting Knowledge in Language and Literacy (SKILL), a narrative intervention designed to improve oral and written narrative abilities in school-age children with or at risk for language and reading disorders. We conducted a multisite randomized controlled trial with 357 students in Grades…

In this article I focus on the use of mixed methods in designing a classroom observation instrument known as the Facilitative Orientation to Reading Teaching (FORT). The instrument was designed to capture the teaching of reading and formed part of a project that took place in 2 Kwa-Zulu Natal primary schools. Participants were 8 teachers and their…

The simple views of reading (SVRs) and writing (SVWs) reflect useful frameworks for the psychoeducational evaluation of literacy difficulties. They describe reading comprehension and written expression as the outcome of oral language, decoding, and transcription skills. Prior research has demonstrated that these components explain the vast…

This study aimed to determine the dimensionality of morphological knowledge by examining different sources of variance. According to the Morphological Pathways Framework ("Levesque et al., Journal of Research in Reading," 44, 10-26, 2021), morphological awareness, morphological analysis and morphological decoding are related, but…
