This mixed-methods, cross-cohort efficacy study evaluated "Just Right Reader's Classroom Libraries" first-grade students across six schools in a diverse Texas district. The Classroom Libraries consisted of decodable literacy resources appropriately matched to instructional needs and were available in English to all students and in…

This mixed-methods, quasi-experimental efficacy study evaluated Just Right Reader's Take-Everywhere Literacy Packs™ with 399 kindergarten students across six schools in a diverse Texas district during the 2024-2025 academic year. This district had a consistent curriculum and access to decodable books, however treatment students received the…

Purpose: Researchers have developed a constellation model of decodingrelated reading disabilities (RD) to improve the RD risk determination. The model's hallmark is its inclusion of various RD indicators to determine RD risk. Classification methods such as logistic regression (LR) might be one way to determine RD risk within the constellation…

Parent tutoring offers potential as a means for assisting the large percentage of students who need to improve their reading skills. The primary purpose of this study was to examine the impact of a reading fluency intervention program when used by parents in the home during the summer months. Specifically, this study evaluated the effects of the…

Situated in the heart of the fertile San Joaquin Valley twenty miles north of Fresno, the city of Madera has a population of 56,710 people. Agriculture is the driving force behind the local economy; the area produces more than 100 crops including raisin grapes, almonds, figs, pistachios, alfalfa, corn, milk, cattle and poultry. The total value of…

Preschool reading readiness is an issue with growing interest. The preschool years provide an opportune time when reading difficulties are more easily altered through exposure to early literacy skills. This paper extends the authors' previous research by examining the kindergarten performance of a cohort of children from a multi-year research…

A fairly recent definition of reading disability (RD) is that in the form of a hybrid model. The model views RD as a latent construct that is manifested through various observable unexpected impairments in reading-related skills and through inadequate response to intervention. The current report evaluated this new conceptualization of RD from an…

Multitiered systems of reading instruction and intervention, including response to intervention, are widely used in early reading by schools to provide more intense services to students who need them. Research using randomized controlled trials has compared innovative Tier 2 interventions to business-as-usual Tier 2 approaches and established a…

The number of applied behavior analysis (ABA) classrooms for students with autism is increasing in K-12 public schools. To inform instruction of students with autism in public school settings, this study examined the relation between performance on mastery learning assessments and standardized achievement tests for students with autism spectrum…

This randomized control study compares the efficacy of two response-to-intervention (RTI) models: (1) Dynamic RTI, which immediately refers grade 1 students with the weakest skills to the most intensive intervention supports (Tier 2 or Tier 3); and (2) Typical RTI, which starts all students in Tier 1 and after 8 weeks, decides whether students who…

The purpose of this study was to determine if the implementation of a Response to Intervention framework had a positive impact on student reading achievement in urban elementary schools. This was a causal-comparative study that examined the reading performance of a sample of kindergarten through grade three students who experienced the Response to…

This paper presents the findings from a randomized control trial study of reading/literacy-integrated science inquiry intervention after 1 year of implementation and the treatment effect on 5th-grade low-socio-economic African-American and Hispanic students' achievement in science and English reading. A total of 94 treatment students and 194…

Since the National Reading Panel report and passage of No Child Left Behind, one particular reading instrument, "Dynamic Indicators of Basic Early Literacy Skills" (DIBELS), has gained nationwide attention. As a result, DIBELS has been used in thousands of schools across the nation as a means of early identification, intervention, and…

This paper presents findings of an efficacy trial examining the effect of a multi-tiered instruction and intervention model on first grade, at risk students' reading outcomes. Schools (n = 16) were randomly assigned to the treatment or control condition. In the fall of Grade 1, students were assigned to an instructional tier on the basis of SAT-10…

This article presents findings of an efficacy trial examining the effect of a multitiered instruction and intervention model on first grade at-risk students' reading outcomes. Schools (N = 16) were randomly assigned to the treatment or control condition. In the fall of Grade 1, students were assigned to an instructional tier on the basis of…
