The extent to which reading achievement is causally impacted by eligibility for special education services due to a learning disability (LD) or speech or language impairment (SLI) is currently unclear. In this registered report, we analyzed U.S. national data from the Early Childhood Longitudinal Study--Kindergarten Cohort of 2010-2011 (ECLS-K:…

One of the most persistent areas of difficulty in mathematics for children with learning disabilities (LDs) and difficulties is fractions. We report the development and initial testing of an intervention designed to increase access to and advancement in conceptual understanding. Our asset-based theory of change--a tested and confirmed learning…

The ability to write informatively is a skill not only required by the U.S. Common Core State Standards but is also essential for preparing students to be successful in college. The purpose of this exploratory study was to evaluate the effects of a self-regulated strategy development (SRSD) informative writing intervention for high school students…

Many students with learning disabilities (LD) do not master basic reading skills, which affects later reading fluency and reading comprehension development. Single-case experimental design (SCED) research yields unique opportunities to better understand which aspects of a basic reading intervention are effective with a particular student,…

Students most at risk for reading-related disabilities frequently struggle with word recognition and oral language, including, in the earliest grades, specific skills related to phonological awareness and vocabulary. Classroom teachers' delivery of high-quality differentiated supplemental instruction may promote reading acquisition for these…

The purpose of this feasibility study was to inform the development of an intervention to support reading and self-regulation for students with significant reading difficulties and disabilities (RDs), including dyslexia. Participants were 21 special educators, dyslexia specialists, and reading interventionists and 48 students in Grades 2 to 4.…

The current study investigated the effectiveness of an intensive writing intervention focusing on mathematical reasoning through written expression. A group pretest--intervention--posttest comparison experimental design was used to implement a 12-lesson intervention, delivered through a combination of Google Classroom and in-person classroom…

Oregon's Effective Behavioral and Instructional Support Systems (EBISS) initiative was implemented in 25 school districts. The initiative trained and coached district leaders and teachers in the use of the EBISS model through the lens of implementation science. The EBISS model integrates school-wide positive behavior intervention and supports…

Students in the United States who receive special education services are entitled to receive an Individualized Education Program (IEP) that provides an appropriate level of benefit. Although IEP content is informed by policy mandates and practice recommendations, research has yet to investigate the degree to which school practice is in alignment.…

This study reports on the instruction provided in district-designed intensive summer reading programs. The Tier 3 intervention was provided to 374 students from 24 school districts who were not meeting the end of third-grade reading benchmarks; students were exiting third grade and entering fourth grade. Observations of the 40 classes were…

This study explored whether initial skill moderated outcomes of Promoting Algebra Readiness, a Tier 2 sixth-grade mathematics intervention targeting conceptual and procedural knowledge of fractions. The study analyzed data from a quasi-experimental pilot study in which at-risk students (N = 198) from Oregon middle schools were assigned to the…

Reading interventions focusing on self-determination can effectively improve the academic performance of students with learning disabilities (LD). This study investigated the effects of a multicomponent reading comprehension strategy intervention, which is based on the Self-Determination Learning Model of Instruction (SDLMI), on the use 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…

The overall purpose of this study was to examine caregivers' adherence to a storybook-reading intervention using latent class analysis (LCA). This study also examined whether adherence was related to child and family characteristics including children's language ability, caregiver education, and whether the child has a disability. Caregivers of…

Students with disabilities in upper elementary grades who read well below grade level often require one-to-one intensive intervention. The following study examines the effects of a combined explicit decoding plus frequency building intervention on consonant-vowel-consonant (CVC) word reading fluency. Participants were two third-grade students and…
