Background: Dyslexia is a specific reading disability characterized by word recognition difficulties that can qualify a student for special education services under the "Individuals with Disabilities Education Act" (IDEA; 2004; Yudin, 2015). As of 2024, 49 US states have legislation defining dyslexia and enumerating for schools…

Purpose: The purpose of this study was to determine if group differences exist in spelling accuracy or spelling errors between kindergarten children with hearing loss and children with normal hearing loss. Method: Participants included 23 kindergarten children with hearing loss and 21 children with normal hearing. All children used spoken English…

Kindergarten reading screening measures typically identify many students as at risk who later meet criteria on important outcome measures (i.e., false positives). To address this issue, we evaluated a gated screening process that included accelerated progress monitoring, followed by a simple goal/reward procedure (skill vs. performance assessment,…

In education research, statistical significance and effect size are 2 sides of 1 coin; they complement each other but they do not substitute for each other. This descriptive study, however, was limited to effect size only because years of experience with Idaho statewide student samples of up to 24,000 the rare outcomes has been t-tests with…

Measuring and identifying risk for reading difficulties at the kindergarten level is necessary for providing intervention as early as possible. The purpose of this study was to examine concurrent validity evidence of two kindergarten reading screeners, Acadience Reading and Texas Primary Reading Inventory (TPRI), as well as diagnostic accuracy at…

Early identification and instruction aimed at addressing potential reading difficulties is the key to preventing prolonged difficulties in learning to read and ensuring that all students are reading with proficiency by the end of third grade. Tier 1 core reading curricula needs to be: (a) evidence based, (b) systematic and structured, (c)…

Various stakeholders, such as policymakers and educators, require diagnostic feedback and actionable test results. One particular context in which fine-grained test results are of utmost importance is English language proficiency (ELP) assessments as they are used for critical decisions for students. Diagnostic classification models (DCMs) afford…

Little research has been conducted on Arabic letter knowledge. This study investigates the nature of Arabic letter knowledge, its dimensionality, and the relative difficulty of letter knowledge items, all within an item response theory (IRT) framework. Three letter knowledge tests were administered to 142 native Arabic-speaking kindergarteners…

These are the appendixes for the report, "Trends and Gaps in Reading Achievement across Kindergarten and Grade 1 in Two Illinois School Districts." This study examined reading achievement data for kindergarten and grade 1 students in two districts in Illinois: District U-46 (Elgin Area Schools) and District 186 (Springfield Public…

Complex research questions often need large samples to obtain accurate estimates of parameters and adequate power. Combining extant data sets into a large, pooled data set is one way this can be accomplished without expending resources. Measurement invariance (MI) modeling is an established approach to ensure participant scores are on the same…

Stagnant standardized test scores keep literacy achievement at the forefront of national education discussions. Increased conversations about the science of reading have propelled investigations into different types of phonics instruction. However, questions still linger such as "Which strategies are most effective for which students?",…

This study examined the role of fidelity in the reading outcomes within a Tier 2 intervention implemented by Spanish kindergarten and first grade school teachers. For this purpose, differences in reading performance growth were analyzed among at-risk students who received a Tier 2 intervention with high fidelity, at-risk students who received the…

Background: The relationship between rapid automatized naming (RAN) and reading has been examined extensively, but there is still a question as to the reason for the relationship. To reduce involvement of alphanumeric and vocabulary knowledge in RAN, and to possibly reduce phonological demands, researchers have suggested using the RAN sizes that…

In-person tutoring has been shown to improve academic achievement. Though less well-researched, virtual tutoring has also shown a positive effect on achievement but has only been studied in grade five or above. We present findings from the first randomized controlled trial of virtual tutoring for young children (grades K-2). Students were assigned…

The purpose of this systematic observation study was to improve our understanding of small-group reading instruction for kindergarten students at risk for reading difficulties (RDs). We aimed to observe and document activity types addressed as well as instructional practices and materials employed during small-group instruction, with a particular…
