Purpose: This longitudinal study examined the contribution of preschool morphological awareness to word reading skills and reading comprehension, as well as to the developmental change of reading ability beyond other well-established oral language and cognitive predictors. A distinction was made between the domains of inflectional and derivational…

Little is known about what contributes to individual differences in reading fluency after accounting for accuracy. Previous research has shown individual differences in the relative growth in word and nonword reading, specifically a pattern in which students who start lower on reading grow more in word than nonword reading ability. The purpose of…

This longitudinal study examined the effectiveness of a progress monitoring method, namely the Multilayer Instruction Model-Progress Monitoring (MIM-PM), which is a word reading fluency measure. It was used from 1st grade onward to predict the overall reading achievement of students in elementary school by tracking their reading achievement over…

The aim of this study was to examine the impact of Reading for Ethiopia's Achievement Developed Community Outreach (READ CO) project intervention on students' oral reading fluency, reading comprehension, academic achievements, and listening comprehension. It also aimed at identifying the students and teachers' awareness and practices about the…

Education has faced unprecedented disruption during the COVID pandemic. Understanding how students have adapted as we have entered a different phase of the pandemic and some communities have returned to more typical schooling will inform a suite of policy interventions and subsequent research. We use data from an oral reading fluency (ORF)…

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…

We use data from oral reading fluency (ORF) assessments to examine COVID-19's effects on children's ORF in over 100 U.S. school districts. Students' development of ORF largely stopped in spring 2020 following the onset of the COVID-19 pandemic. In fall 2020, students' gains in reading were stronger and similar to prepandemic rates. However, fall…

Despite the widespread use of rapid automatized naming (RAN) tasks in reading and mathematics research, little is known about the direction of their relation. Thus, in this longitudinal study, we examined the direction of the relation between RAN and reading/mathematics accuracy and fluency. One-hundred and eighty-three Grade 1 Chinese children…

Computerized game-based assessment (GBA) system for screening reading difficulties may provide substantial time and cost benefits over traditional paper-and-pencil assessment while providing means also to individually adapt learning content in educational games. To study the reliability and validity of a GBA system to identify struggling readers…

Education has faced unprecedented disruption during the COVID-19 pandemic; evidence about the subsequent effect on children is of crucial importance. We use data from an oral reading fluency (ORF) assessment--a rapid assessment taking only a few minutes that measures a fundamental reading skill--to examine COVID's effects on children's reading…

The Early Grade Reading Assessment (EGRA) is used to evaluate studies and monitor projects that address reading skills in low- and middle-income countries. Results are often described solely in terms of a passage-reading subtask, thereby overlooking progress in related skills. Using archival data of cohort samples from Uganda at two time points in…

This study quantified the possible learning losses in reading and math skills among a sample of Finnish Grade 3 children (n = 198) who spent 8 weeks in distance learning during the first wave of the COVID-19 pandemic in spring 2020. We compared their reading and math skill development trajectories across Grades 1, 2, and 4 to a pre-COVID sample (N…

This study examines associations between leisure reading and reading skills in data of 2,525 students followed from age 7 to 16. As a step further from traditional cross-lagged analysis, a random intercept cross-lagged panel model was used to identify within-person associations of leisure reading (books, magazines, newspapers, and digital…

This study explores the co-development of two related but separate reading skills, reading fluency and reading comprehension, across Grades 1-4. A bivariate biometric dual change score model was applied to longitudinal data collected from 1,784 twin pairs between the ages of 6 and 10 years. Grade 1 skills were influenced by highly overlapping…

Education has faced unprecedented disruption during the COVID-19 pandemic; evidence about the subsequent effect on children is of crucial importance.
