The authors of this position paper argue that there is currently very little evidence-based practice in relation to learners with severe learning disabilities (SLD) and profound and multiple learning disabilities (PMLD), and that which there is, has often been badly used and/or abused. More specifically, we argue that relevant educational research…

Single-case designs substantiate the effectiveness of interventions for people with disabilities and other populations through the repeated measurement of behavior over time. Consequently, employing accurate and reliable systems of measurement is critical to the validity of single-case designs. Much of the data in single-case research are…

As researchers and practitioners have increasingly become interested in what practices are evidence based and for whom in education, different sets of quality indicators and evidence-based practice standards have emerged in the field of special education. Practices are commonly suggested as evidence based, even without a best evidence synthesis on…

Purpose: Students with learning disabilities (LD) often struggle to initiate writing tasks and have difficulty devoting sufficient resources to complete written compositions. Educators must determine the most effective writing instruction to help these students. Evidence-based educational practices benefit from research reviews such as systematic…

Feedback can have a positive effect on student performance in the classroom, however not all feedback is equal, and some types of feedback can actually worsen performance. Little is known about whether existing evidence-based reading programs provide the feedback that has been shown to enhance student performance. The purpose of this study was to…

People with disabilities have always existed in our communities and societies; however, how we treat them has always been an issue. For example, for a long time, people with physical disabilities received more attention than those with disabilities that we could hardly see (e.g., learning disabilities). Very early research focused on students with…

In this rejoinder, the authors describe the aim of the original study as an effort to conduct a critical test of an important postulate underlying the Cross-Battery Assessment PSW approach (XBA PSW; Kranzler, Floyd, Benson, Zaboski, & Thibodaux, this issue). The authors used classification agreement analysis to examine the concordance between…

This brief report summarizes research on dyslexia. It is intended to provide an initial look at this common type of learning disability that impacts 1 in 5 students. Included in the brief are links to the original source material and to supplementary resources and videos to learn more.
