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 Home Literacy model predicts different outcomes depending on formal and informal literacy practices carried out at home. However, this model does not explicitly consider the potential differences that the media (paper vs. tablets) in which these practices are carried out can have on performance. The present study explored this issue.…

The visual system is tuned by its inputs. The behavior of reading offers a unique way to examine tuning for visual representations (letters) because readers have massive experience recognizing letters in a systematic context (reading). One aspect of reading is that letters are highly crowded within words, which severely limits their…

Reading comprehension (RC) is a multi-faceted construct but is often assessed with a single instrument. Previous research has highlighted that commonly used RC tests are only mildly correlated and vary in the skills they assess, including the differential contribution of oral language and decoding to children's performance. Our study, framed…

Two recent computational models of reading development propose that irregular words are read using a combination of decoding and lexical knowledge but differ in assumptions about how these sources of information interact and about the relative importance of different aspects of lexical knowledge. We report developmental data that help to…

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 study examines the development of reading comprehension (RC) in Spanish heritage language (HL) learners in the Midwest United States. While extensive research exists on RC in monolingual English-speaking populations, applying reading science models such as the Simple View of Reading (SVR) in HL or bilingual contexts remains under-researched.…

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…

Purpose: The lexical quality (LQ) hypothesis predicts that a skilled reader's lexicon will be inhabited by a range of low- to high-quality items, and the probability of representing a word with high quality varies as a function of person-level, word-level, and item-specific variables. These predictions were tested with spelling accuracy as a gauge…

Background: South Africa's PIRLS 2021 outcomes revealed that learners struggle with comprehension. The reasons for poor reading need to be identified and addressed to stem this challenge. Aim: This study assessed Sesotho Grade 4 learners' knowledge of simple and complex letter sounds, their oral reading fluency and the relationship to their oral…

Proficient reading requires the ability to analyze words for various properties, including pronunciation, meaning, and syntactical function. However, most instruction in word analysis is limited to phonics instruction provided in the early elementary grades. For older students, whose words largely center units of meaning, or morphemes, early…

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…

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…

Although there is evidence for a close link between early phonological skills and the development of vocabulary and decoding abilities, it is less clear which factors modulate the development of phonological skills. This study longitudinally explored the relation of contextual family variables on the development of phonological skills in 104…

This study takes a more holistic look at reading support, to explore what else is happening in this teaching and learning context, beyond the acquisition of a more secure knowledge of decoding skills. Children are deemed in need of a reading support intervention when their literacy skills are assessed as being significantly below the levels…
