Competence with rational numbers is essential for mathematics proficiency in secondary mathematics. However, many students struggle with rational number concepts, and students with mathematics difficulties struggle even more. The purpose of this study was to examine the effects of an intervention that incorporated the use of explicit instruction…

Multifactorial models of dyslexia have expanded how we consider heterogeneity within the population of children with dyslexia. These models are predicated on the idea that cognitive/linguistic risk factors are not deterministic but instead probabilistic, with the likelihood of difficulties involving an interaction between risk and protective…

With the shift from No Child Left Behind (NCLB) to Every Student Succeeds Act (ESSA), accountability models are being changed. Given the past 15 years of reporting on student subgroups and 10 years using various growth models, accountability systems can now be better informed. In this study, we analyze identification and services of students with…

Science, Technology, Engineering, and Mathematics (STEM) education initiatives have placed pressure on teachers to bring technology tools into classroom, including three-dimensional (3D) printing. Yet, little research has examined what specific math skills are required for 3D printing technology. This article describes a follow-up analysis of…

Alternative Individualized Education Program (IEP) dispute resolution models should respond to limitations of current options. An experimental IEP dispute resolution program provides parents and schools with an evidence-supported neutral perspective on what is needed for free and appropriate education (FAPE) and least restrictive environment…

Accumulating research has established explicit mathematics instruction as an evidence-based teaching practice. This study utilized observation data from a multi-year efficacy trial to examine the longitudinal effects of a core kindergarten mathematics program on the use of explicit mathematics instruction among two distinct groups of teachers: one…

As a result of the upcoming Federal reauthorization of the Individuals With Disabilities Education Improvement Act (IDEA), practitioners and researchers have begun vigorously debating what constitutes evidence-based assessment for the identification of specific learning disability (SLD). This debate has resulted in strong support for a method that…

This study examined the number of writing samples needed to obtain a reliable estimate of young struggling writers' capabilities. It further assessed if performance in one genre was reflective of performance in other genres for these children. Second- and third-grade students (81 boys, 56 girls), who were identified as struggling writers in need…

Using structural equation modeling, the study tested a theoretical model linking family background, student attributes, and college success. The sample consisted of 346 students with learning disabilities (LDs) who enrolled in college between 2004 and 2012. The data were taken from the public files of the Education Longitudinal Study: 2002. The…
