Despite evidence that tiered instruction within response to intervention (RTI) frameworks is important for students with reading difficulties, no complementary professional development (PD) research demonstrates how teachers can develop knowledge necessary to implement coordinated evidence-based instruction across instructional tiers. One…

Students with mathematics difficulties often struggle with conceptual and procedural understanding of fractions. Self-regulated strategy development (SRSD) is an evidence-based framework for teaching a variety of academic skills, including mathematics. The purpose of this study was to extend preliminary work using "SRSD Fractions" to…

As school psychologists we are well trained with using and interpreting a variety of psychometric instruments, yet there are several studies that indicate that school psychologist's interpretive practices veer off the intended path. The application of assessment to the process of identification of specific learning disabilities (SLD) has been…

In the USA, many states have adopted response to intervention or multi-tiered systems of supports to provide early intervention. However, there is considerable variability in how states and schools implement RTI. Teachers are responsible for using student data from RTI to inform instructional decisions for students with or at risk for dyslexia, so…

Implementation of evidence-based practices (EBPs) is paramount to students' development of mathematics proficiency. This study investigated "practice-based evidence" of interventionists' actual use of explicit mathematics instruction, a well-established EBP. Specifically, this study analyzed direct observation data collected in a…

Implementation of evidence-based practices (EBPs) is paramount to students' development of mathematics proficiency. This study investigated "practice-based evidence" (Green, 2008) of interventionists' actual use of explicit mathematics instruction, a well-established EBP. Specifically, this study analyzed direct observation data…

Writing is an essential skill and outcome for academic and professional success, but the call for evidence-based practices and instructional differentiation to support all student-writers' needs has yet to be sufficiently addressed. The Common Core State Standards' Initiative resurfaced a focus on writing instruction and brought attention to…

We review the evolution of the conceptualisation of dyslexia and along with it the current, 21st century definition of dyslexia. Our starting point is the seminal report by Pringle Morgan in 1896, followed by early 20th century reports by Hinshelwood, and continuing with concepts of brain injury and minimal brain dysfunctions then to the emergence…

This article considers the cost of poor decision making in school psychology, especially with regard to determining eligibility for special education under the category of specific learning disability. One common costly decision made by school psychologists is failing to use evidence-based assessment and intervention procedures that are likely to…

Promising findings from controlled research studies often fail to be transferred to and implemented in schools successfully. This problem is particularly apparent when considering implementation of evidence-based practices related to complex systems such as response to intervention (RTI) and other multitiered intervention frameworks in…

Students with severe and persistent academic or behavioral challenges may benefit from data-based individualization (DBI). Starting with an evidence-based standard protocol and systematic progress monitoring, teachers can evaluate growth and implement individualized interventions to meet students' needs. Specifically, this article addresses the…

In 2010, "Intervention in School and Clinic" undertook a project to interview "giants" in the fields of learning disabilities and emotional/behavioral disabilities. The purpose of the interviews was to document the perspectives and reflections of leaders who had contributed to their respective fields over several decades (i.e.,…

This article explains a process for improving specific learning disabilities (SLD) eligibility guidelines in a special education cooperative in Nebraska. The Central Nebraska Support Services Program (CNSSP) is a special education cooperative that serves four public school districts and seven parochial schools in central Nebraska. Children birth…

The purpose of this study was to examine the changes in initial eligibilities of elementary students across Tennessee since the implementation response to intervention (RtI), as well as understand the perceptions of elementary school psychologists related to those changes in identification and eligibility. RtI is a Tennessee mandated initiative,…

Response to intervention (RTI) emerged from the 2004 reauthorization of the Individuals with Disabilities Education Act, but the roots of RTI are found embedded within the history of the field of learning disabilities (LD) as well as other sources of influence. In what follows, we provide a brief history of LD and highlight the connection between…
