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…

The purpose of this registered report study was to determine the effects of explicit text structure instruction on the expository text comprehension of students with language and learning disabilities (LLD) using a multiple baseline design across conditions (e.g., compare-contrast and cause-effect) and participants. Participants included four…

This systematic review article summarizes the effects of explicit text structure instruction on expository text comprehension for adolescents with learning disabilities or at risk for reading failure. A thorough literature search with four databases and backward citation search identified nine studies published in the past 22 years for inclusion…

Instructional interactions that occur between teachers and students around foundational mathematics topics are critical for supporting mathematical proficiency among students with mathematics learning disabilities (MLD). This study investigated whether the initial mathematics skill of 880 kindergarten students at risk of MLD predicted the quantity…

This exploratory case study used a mixed-methods pre-/post-intervention design to study the impact of an intervention on reading comprehension, annotation, and discussion quality. Five third-grade struggling readers who were part of a Tier 2 reading comprehension group were apprenticed into holding close-reading discussions of informational text.…

Schema-based instruction (SBI) was used to teach nine middle school students with high-incidence disabilities (HID) to solve proportional reasoning word problems. A multiple-baseline-across-groups design was used to determine student understanding of the SBI process. The design consisted of three phases including baseline, SBI process, and…

The number of students with learning disabilities (LD) enrolling in postsecondary education has increased rapidly over the past decade. It is imperative to investigate what interventions have been used to assist students with LD in achieving academic success. To examine the interventions currently used to support students with LD in postsecondary…

This article presents an update and extension of the research on instructional methods for vocabulary learning by secondary-age students with learning disabilities. Seven studies that have been published since the last comprehensive review of the research were located. Four instructional methods were found to be the most effective: mnemonic…

Over the last two decades, the significance of academic achievement for students with disabilities in K-12 education has increased. To meet the needs of this population, educators turned to innovative strategies and technologies for instructional support in the classroom. For students with a learning disability, the need for such solutions is…

Implementing an integrated sequence of concrete-representational-abstract depictions of mathematics concepts (CRA-I) can improve the mathematics achievement of students with disabilities, and explicit instructional strategies involving problem-solving heuristics and student verbalizations can help facilitate students' conceptual understanding of…

This article examined the extent to which administrative decisions that affected the implementation fidelity of Direct Instruction programs were related to student achievement. Data from three studies showed that administrative decisions that disregarded recommended protocols regarding teacher training, teacher preparation, and student schedules…

The purpose of this exploratory study was to determine whether learning preferences of secondary students identified with concomitant learning disabilities (LD) and emotional disturbance (ED) align with the instructional method with which they best learned mathematics. Responses to a preference survey given before and after instruction were…

The production of an effective mathematics curriculum begins with a scientific development, evaluation, and revision framework. The purpose of this study was to conduct an initial investigation of a recently developed Tier 2 mathematics curriculum designed to improve the outcomes of first grade students at risk for mathematics difficulties (MD).…

The authors report the effects of a single-case, multiple-probe design investigation for students with learning disabilities (LD) in Grades 4 and 5. Seven students classified as LD and with persistent difficulty with informational-text comprehension from two elementary schools participated. The study compared social studies learning across two…

The purpose of this study was to investigate the effectiveness of explicit, direct, and generative strategy training and working memory capacity (WMC) on mathematical word problem-solving accuracy in elementary schoolchildren. In this study, children in third grade ("N" = 82) identified as at risk for math difficulties (MD) were randomly…
