In this longitudinal study, we examined what kind of profiles of reading fluency and spelling skills could be identified among pupils (N = 467) and how stable these profiles were during the first three years of school. We also investigated how monolingual (Swedish) and simultaneously bilingual (Finnish-Swedish) pupils and gender were distributed…

This study aimed to describe 1-year changes in students' vocabulary in written narratives. Secondary aims included examination of accuracy and the relationship between lexical diversity and achievement. Participants included 749 students in first through eighth grades. Within-subjects 1-year change in diversity, productivity, and accuracy was…

The purpose of the present research was to provide information to the community about the reading subskill profiles of children with dyslexia in primary and secondary school students. 175 children (aged 7-15 yrs) were examined on a varied set of phonological coding, spelling and fluent reading tasks. For this purpose, students' fluent reading were…

This study investigated relationships among the reading fluency, word recognition, language background, and reading achievement in second through fifth graders. Among the 250 students sampled, 70% were within word pattern (WWP) spellers. These WWP stage spellers were remarkably similar in reading, regardless of grade and Limited English Proficient…

Considerable evidence supports that close to two thirds of all fourth-grade students read at less than adequate levels on reading achievement tests and that the problem has persisted for decades. This study of 1,064 third-grade students at risk for reading failure uses path analytic techniques to measure a hypothesized model linking developmental…

In this pilot study, we evaluated the effects of the online computer-based training programme 'Lexilogy-Greek' on the reading and spelling performance of young poor readers and spellers. The training is based on psycholinguistic principles that emphasise the importance of acquiring efficient phonological as well as morphological knowledge in…

Purpose: To assess strengths and weaknesses of the reading level (RL) match approach and its potential to generate insights regarding the cognitive foundations of reading ability and disability. Method: We applied RL-match design to a sample of 2nd-6th graders reading a consistent orthography, Russian, using an "extreme phenotype"…

Understand the science of reading and how to implement evidence-based instruction to increase the reading and writing achievement of pre-K-6 students, including those at risk for reading difficulties. Fully revised and updated, this core text covers the research base for structured literacy instruction and practical guidance on the essential…

Background: Task avoidance is a significant predictor of literacy skills. However, it remains unclear whether the relation between the two is reciprocal and whether it is affected by the type of literacy outcome, who is rating children's task avoidance, and the children's gender. Aim: The purpose of this longitudinal study was to examine the…

A controlled quasi-experimental design was used to evaluate the effects of the use of MindPlay Virtual Reading Coach on participants' reading and spelling achievement. After attrition, participants included 170 students enrolled in eight second-grade classrooms (four classrooms in each school) in two public elementary schools in the southwestern…

This study investigated the feasibility of multicomponent linguistic awareness intervention on early literacy skills in at-risk kindergarteners. Seventeen students, including native Spanish-speaking English language learners (n = 10) and native English speakers (n = 7), participated in a 6-week small-group therapy program, for a total of 12…

This paper investigates how pupils' growth trajectories in three language domains (reading fluency, spelling, and reading comprehension) are related to their own socioeconomic and ethnic background and to the socioeconomic and ethnic composition of their primary school. Using multilevel piecewise growth curve analysis, the growth trajectories…

The concept of Matthew effects in reading development refers to a longitudinally widening gap between high achievers and low achievers. Various statistical approaches have been proposed to examine this idea. However, little attention has been paid to psychometric issues of scaling. Specifically, interval-level data are required to compare…

The authors used a large data set (N = 1,011,549) to examine literacy growth over a single school year comparing general education (GenEd) students to three high-risk subgroups: English language learners (ELL), those with a specific learning disability (LD), and those identified as both LD and ELL (LD-ELL) in students in Grades 3-10. The authors…

The What Works Clearinghouse (WWC) has updated its 2009 intervention report for SuccessMaker®, a set of computer-based courses designed to supplement regular K-8 reading instruction. The program is designed to improve skills in areas such as concepts of print, phonological awareness, phonics, fluency, vocabulary, comprehension, grammar, and…
