This simulation study examines the characteristics of the Explanatory Item Response Model (EIRM) when estimating treatment effects when compared to classical test theory (CTT) sum and mean scores and item response theory (IRT)-based theta scores. Results show that the EIRM and IRT theta scores provide generally equivalent bias and false positive…

Panel mediation models and fixed-effects models were used to explore longitudinal relations among parents' reactions to children's displays of negative emotions, children's effortful control (EC), and children's math achievement (N = 291; M age in fall of kindergarten = 5.66 years, SD = 0.39 year) across kindergarten through…

The purpose of this study was to determine to what extent two major specific learning disability (SLD) criteria, including a student's level of academic achievement and rate of improvement (ROI), predict multidisciplinary evaluation teams' decision-making regarding referral for special education evaluation and special education eligibility.…

Although the general development of mathematical abilities in primary school has been the focus of many researchers, the development of place value understanding has rarely been investigated to date. This is possibly due to the lack of conceptual approaches and empirical studies related to this topic. To fill this gap, a theory-driven and…

The development of scientific thinking was assessed in 1,581 second, third, and fourth graders (8-, 9-, 10-year-olds) based on a conceptual model that posits developmental progression from naïve to more advanced conceptions. Using a 66-item scale, five components of scientific thinking were addressed, including experimental design, data…

Low reading skills constitute a serious achievement problem. Although there are remedial support in schools, between 2% and 6% of the student population continues to show persistent reading difficulties despite intensive intervention. The research problem in this study addressed the lack of effective reading interventions for students who were in…

Few empirical investigations have evaluated learning disabilities (LD) identification methods based on a pattern of cognitive strengths and weaknesses (PSW). This study investigated the reliability of LD classification decisions of the concordance/discordance method (C/DM) across different psychoeducational assessment batteries. C/DM criteria were…

Response to Intervention (RtI) is a multi-tiered approach to provide evidence-based instruction to all students. Within a RtI paradigm, teachers and other professionals collaborate to design interventions for students who are at-risk for a learning disability. Despite the widespread use of RtI paradigms in educational settings, few studies have…

We explored the usefulness of first and second grade reading measures and responsiveness criteria collected within a response-to-intervention (RtI) framework for predicting reading disability (RD) in third grade. We used existing data from 387 linguistically diverse students who had participated in a longitudinal RtI study. Model-based predictors…

Improving student performance for high-need student populations by improving the use of data in decision-making for early reading intervention programs in northwest Florida is the focus of this research to practice effort. The study is conceptually based on using a relational-feedback intervention (RFI) database model in early learning…

The present study seeks to evaluate a hybrid model of identification that incorporates response to instruction and intervention (RTI) as one of the key symptoms of reading disability. The 1-year stability of alternative operational definitions of reading disability was examined in a large-scale sample of students who were followed longitudinally…

In this study, we tested the outcomes of access to a response to intervention (RtI) model in kindergarten or in first grade on end-of-Grade-2 reading achievement and placement in special education. Across five schools, 214 students who began having access to Tier 2 intervention in kindergarten or first grade were compared in Grades 1 and 2 with…

To determine whether formative writing assessments that are directly tied to everyday classroom teaching and learning enhance students' writing performance, we conducted a meta-analysis of true and quasi-experiments conducted with students in grades 1 to 8. We found that feedback to students about writing from adults, peers, self, and computers…

The purpose of this study is to investigate teachers' perceptions of the functionality and effectiveness of the response to intervention model. Using a response to intervention (RTI) framework has become a priority for school district as they move to meet federal legislative mandates. Through this study teachers in the southwestern part of the…

Patterns of identification for special education services across three cohorts of students in kindergarten through third grade before and after implementation of a schoolwide, three-tier reading prevention model in one large school district are reported. The first cohort of students represents a historical control group that did not participate in…
