This study examined the diversity in feelings of loneliness among high-ability students. Individual differences (intelligence level, giftedness label, and personality) and differences in the social context (peer acceptance, peer rejection, victimization, and friendship quantity) of adolescents were considered as predictors of loneliness.…

Previous research illustrated that reading comprehension and science performance correlate highly. Because students with specific learning disorders with impairments in reading (SLD-IR) show deficits in reading comprehension, they may struggle to perform in science. As language in science is characterized by linguistic complexity, the question…

An emerging body of research suggests that incorporating randomization schemes in single-case research designs strengthens study internal validity and data evaluation. The purpose of this study was to test the utility and feasibility of a randomized alternating-treatment design in an investigation that compared the combined effects of vocabulary…

The purpose of this study was to evaluate the types of spelling errors made by children with mild to moderate hearing loss (CMMHL) compared with children with typical hearing (TH) and to determine if types of spelling errors were related to linguistic or audiologic factors. CMMHL and TH completed measures of spelling, spoken language, speech…

Proportional reasoning is the cornerstone of many higher-level mathematics topics. We evaluated the sustainability effects of schema-based instruction (SBI) on proportional reasoning and the impact of professional development (PD) on the instructional practices of two cohorts of seventh-grade teachers (i.e., SBI-experienced-teacher implementers,…

The present study used a regression discontinuity approach to test whether schema-based instruction (SBI) was effective for students identified with varying levels of mathematics difficulties (MD) who received Tier-1 instruction. The performance of these students was compared to similar students who received business-as-usual Tier-1 instruction.…

This study utilized secondary analyses of a randomized controlled trial and investigated the extent to which prestest word identification efficiency, reading fluency, and vocabulary knowledge moderated the effects of an intervention on reading comprehension outcomes for struggling readers in sixth through eighth grades. Given that the experimental…

To examine the experiences of victimization and bullying among gifted students and their general education peers, we applied a latent transition analysis with longitudinal data from 299 gifted and 689 general education students (fifth to ninth graders). We identified 4 latent statuses for victimization (4.8%-5.2%, frequent victims; 7.4%-12.2%,…

This randomized controlled study investigated the efficacy of a Tier 1 intervention--schema-based instruction--designed to help students with and without mathematics difficulties (MD) develop proportional reasoning. Twenty seventh-grade teachers/classrooms were randomly assigned to a treatment condition (schema-based instruction) or control…

The authors conducted a multiple-baseline study to investigate the effects of a computer-based graphic organizer (CBGO) with embedded self-regulated learning strategies on the quantity and quality of persuasive essay writing by students with high-incidence disabilities. Ten seventh- and eighth-grade students with learning disabilities, emotional…

This study used a statewide longitudinal sample to examine mathematics achievement gaps and growth in students with and without disabilities and to examine the impact of different methods of determining disability group membership on achievement gaps and growth. When disability status was determined on the basis of special education placement each…

Research on bullying is an important avenue for understanding the social integration of students in special education. Focused on 3,305 students who self-reported victimization of two to three times per month or more, this study compared the pattern of verbal, relational, and physical bullying among students in general education and special…

A pretest-posttest cluster-randomized trial involving 31 middle schools and 335 students with disabilities tested the effects of combining explicit and anchored instruction on fraction computation and problem solving. Results of standardized and researcher-developed tests showed that students who were taught with the blended units outscored…

This study reports the effectiveness of a year-long, small-group, tertiary (Tier 3) intervention that examined 2 empirically derived but conceptually different treatments and a comparison condition. The researchers had randomly assigned all students to treatment or comparison conditions. The participants were seventh- and eighth-grade students…

This study investigated the efficacy of a package of accommodations for poor readers in Grade 7. Students with and without word reading disabilities were randomly assigned to take an experimental version of a high-stakes reading comprehension test in 1 of 3 formats: (a) standard administration, (b) read aloud accommodations with 1-day…
