Vocabulary knowledge at school entry is a robust predictor of later reading achievement. Many children begin formal reading instruction at a significant disadvantage due to low levels of vocabulary. Until recently, relatively few research studies examined the efficacy of vocabulary interventions for children in the early primary grades (e.g., before fourth grade), and even fewer addressed vocabulary intervention for students at increased risk for reading failure. In more recent work, researchers have begun to explore ways in which to diminish the "meaningful differences" in language achievement noted among children as they enter formal schooling. This article provides a review of a particularly effective model of vocabulary intervention based on shared storybook reading and situates this model in a context of tiered intervention, an emerging model of instructional design in the field of special education. In addition, we describe a quasi-experimental posttest-only study that examines the feasibility and effectiveness of the model for first-grade students. Participants were 224 first-grade students of whom 98 were identified as at risk for reading disability based on low levels of vocabulary. Results of a multivariate analysis of variance revealed significant differences on measures of target vocabulary knowledge at the receptive and context level, suggesting that students at risk for reading failure benefit significantly from a second tier of vocabulary instruction. Implications for classroom practice as well as future research are provided.

Students with disabilities contribute to the diversity of postsecondary campuses but face many unique challenges in completing their programs of study. The purpose of this systematic review was to develop an understanding of what is known about persistence in and graduation from higher education programs for students with disabilities, focusing specifically on malleable student-and institution-level factors that may influence persistence. This review integrates findings from studies that analyzed qualitative (16 studies) or quantitative (10 studies) sources of data. Quantitative data were converted into odds ratios, to allow for comparison across studies, and common themes were identified across the qualitative data. As a result of the integrated review, 13 facilitators, falling within three major domains (i.e., personal characteristics, academic and social engagement, and accommodations) emerged as potentially related to postsecondary education success. This review provides a starting point for institutions and researchers as they work to advance postsecondary students with disabilities in achieving their academic and future goals.

The purpose of this article was twofold: (1) to explore the feasibility of the regression discontinuity design (RDD) in response-to-intervention implementation research and (2) to expand upon the limited research on vocabulary instruction for kindergarten students who are at risk for reading failure due to limited vocabularies. This pilot study employed an abbreviated, prototypical tiered instructional model to deliver vocabulary instruction to both at-risk kindergarten students and students not at risk for reading failure. The study was designed using RDD and the data were analyzed using a regression-based analytic model. The pros and cons of this research design, specifically in regards to learning disabilities research, is examined.

There is a robust body of psychological research linking youth mental health and academic achievement. However, students in early childhood are rarely represented in this research, and children with disabilities and/or neurological differences are virtually absent. Thus, the present pilot study explored the effects of a structured psychoeducation program designed to enhance school-based wellbeing (SBWB) for young students who are neurodivergent (ND). This study utilized a quasi-experimental design to investigate the effects of the Student Strengths Safari intervention on (1) students’ self-reported covitality and (2) teacher-rated executive functioning to (3) examine data for evidence of a dual-factor model of SBWB. Two classrooms in a suburban, Mid-Atlantic private school were randomly assigned to the waitlist control group (n = 14) (1st grade) and the intervention group (n = 10) (2nd grade), and quantitative data were analyzed at pretest and posttest to determine intervention outcomes. Key findings produced evidence to support (a) a statistically significant interaction effect for improvements in executive functioning relative to the waitlist control group (p = 0.011), and (b) the utility of a new theoretical dual-factor model to advance SBWB for ND students in early elementary education.
