The International Dyslexia Association definition of dyslexia was updated 20 years ago and has been referenced frequently in research and practice. In this paper, researchers from the Florida Center for Reading Research consider the components of the definition and make recommendations for revisions. These include recognizing the persistence of…

Background: Failure to learn early reading skills leads to lower reading comprehension later in elementary school (Double et al., 2019; Paige et al., 2019), which can then lead to poverty, underemployment, and increased likelihood of being incarcerated (World Literacy Foundation, 2018). Early reading skills are best developed in kindergarten…

The purpose of this qualitative case study was to explore how K-2 teachers perceive the effectiveness of multi-sensory phonics methods used in conjunction with a standards-based reading curriculum on students' reading acquisition skills, students' decoding abilities, and student engagement in an inclusive classroom at a public charter school in…

In a quasiregular orthography like English, children inevitably encounter irregular words during reading. Previous research suggests successful reading of an irregular word depends at least partially on a child's ability to address the mismatch between decoded form and stored word pronunciation, referred to as a child's set for variability, and…

This study describes the development of a special education teacher observation protocol detailing the elements of effective decoding instruction. The psychometric properties of the protocol were investigated through many-facet Rasch measurement (MFRM). Video observations of classroom decoding instruction from 20 special education teachers across…

The simple view of reading (SVR) proposes that performance in reading comprehension is the result of decoding and linguistic comprehension, and that each component is necessary but not sufficient for reading comprehension. In this study, the joint and unique predictive influences of decoding and linguistic comprehension for reading comprehension…

This investigation examined the structural relations among latent variables of language, decoding, and reading comprehension, invariance of the patterns of predictions, and unique and common variance over two years in grade cohorts 5 to 6, 7 to 8, and 9 to 10. Participants were 321 students in grade 5 in six elementary schools, 299 students in…

Children with weak decoding skills often struggle to learn multisyllabic words during reading instruction. The primary purpose of this study was to investigate the extent to which initial response to morphological awareness instruction, along with specific language and cognitive variables (i.e., phonological awareness, rapid naming, orthographic…

The present study explored the reading skills of a sample of 48 adults enrolled in a basic education program in northern Florida, United States. Previous research has reported on reading component skills for students in adult education settings, but little is known about eye movement patterns or their relation to reading skills for this…

The purpose of this study was to examine construct validity of methods of calculating lexical diversity in written narrative samples relative to children's performance on a reading vocabulary measure. For 234 children in first to fifth grade, written narratives were examined and compared between grades for number of different words (NDW), total…

The present study examined the reading comprehension and receptive vocabulary skills of children with poor reading comprehension despite adequate decoding using a regression-based matching technique. Participants included five cohorts of children who were identified as typical readers (N = 70,493 - 75,553) or as children with specific reading…

The present study explored the reading skills of a sample of 48 adults enrolled in a basic education program in northern Florida, United States. Previous research has reported on reading component skills for students in adult education settings, but little is known about eye movement patterns or their relation to reading skills for this…

Confirmatory factor analyses of data from 1,501 kindergarten to 5th-grade children who completed 3 measures of decoding, 3 measures of reading comprehension, and 3 measures of listening comprehension as part of a larger study were used to identify the dimensionality of reading skills across elementary school. A 1-factor (reading) model was the…

Reading impairment is more common in males, but the magnitude and origin of this gender difference are debated. In a large-scale study of reading impairment among 491,103 beginning second-graders, gender differences increased with greater severity of reading impairment, peaking at a ratio of 2.4:1 for a broad measure of fluency and a ratio of…

Relations between reading and writing have been studied extensively, but the less is known about the developmental nature of their interrelations. This study applied latent change score modeling to investigate longitudinal relations between reading and writing skills at the word, sentence, and text levels. Latent change score models were used to…
