Most students with reading difficulties struggle to read words. We examined intervention effects for students with "significant" word reading difficulties (SWRD; standard score of 80 on at least one pretest measure of word reading), which includes individuals with or at risk for dyslexia. We investigated: (a) What are the effects of…

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…

Reading comprehension growth trajectories from 3rd to 7th grade were estimated for 99,919 students on a state reading comprehension assessment. We examined whether differences between students in general education (GE) and groups of students identified as exceptional learners were best characterized as stable, widening, or narrowing. The groups…

The present study aimed to examine the relationship between letter processing and word processing skills in deaf and hearing readers. The participants were 105 students (51 of them hearing, 54 of them deaf) who were evenly and randomly recruited from two levels of education (primary = 3rd-4th graders; middle = 6th-7th graders). The students were…

Two experiments were conducted to test the hypothesis that sentence processing is an essential mediatory skill between word recognition and text comprehension in reading. In Experiment 1, a semantic similarity judgement task was used with children from Grade 2 to Grade 9. They had to say whether two written sentences had the same (or very similar)…

The present study investigates differences in the word-reading process between individuals reading in a deep (unpointed Hebrew) and a shallow orthography (Turkish). The participants were 120 students evenly and randomly recruited from three levels of education (primary = 3rd-4th graders; middle = 6th-7th graders; high = 9th-10th graders). The…

Three visual priming experiments using three different prime durations (60 ms in Experiment 1, 250 ms in Experiment 2, and 800 ms in Experiment 3) were conducted to examine which properties of morphemes (form and/or meaning) drive developing readers' processing of written morphology. French third, fifth, and seventh graders and adults (the latter…

This article presents empirical evidence challenging the received wisdom that a nonword-reading deficit is a characteristic trait of disabled readers. On the basis of 2 large-scale empirical studies using the reading-level match design, we argue that a nonword-reading deficit is the consequence of normal developmental differences in word-specific…

The acquisition of reading skill was studied in 503 Italian children in first to eighth grade using a task that required reading of lists of words and non-words. Analysis of the metric characteristics of the measures indicated that reading speed but not accuracy was normally distributed across all ages considered. The role of specific effects…

This facilitator's guide is designed to assist professional learning communities (PLCs) in applying evidence-based strategies to help K-8 English learners acquire the language and literacy skills needed to succeed academically. Through this collaborative learning experience, educators will expand their knowledge base as they read, discuss, share,…

These handouts, which are meant to accompany the facilitator's guide, are designed to assist professional learning communities (PLCs) in applying evidence-based strategies to help K-8 English learners acquire the language and literacy skills needed to succeed academically. The facilitator's guide uses a five-step process for collaborative…

This study investigated the development of automatic word recognition processes, in particular the development of the morphological level of processing. We examined masked priming of Hebrew irregular forms at two levels of reading experience. Both third- and seventh-grade children showed morphological priming for defective roots when primes and…

The authors reviewed all peer-reviewed studies with participants from preschool to Grade 8 for this meta-analysis of morphological interventions. They identified 22 applicable studies. Instructional effects (Cohen's d) were averaged by linguistic outcome categories (morphological sublexical, non-morphological sublexical, lexical, and supralexical)…

Reading fluency has traditionally been viewed as a goal of reading that is taught and mastered in the elementary grades. In this article we challenge that notion by exploring the role of reading fluency as a contributor to reading proficiency and difficulty among intermediate and middle grade students. We assessed reading fluency development among…

This paper considers the development of school students' ability to define three terms that are fundamental to statistical literacy: sample, random, and variation. A total of 738 students in grades 3, 5, 7, and 9 were asked in a survey to define and give an example for the word "sample." Of these, 379 students in grades 7 and 9 were also asked…
