Scaling up scientifically validated interventions involves attending to characteristics of the distinct contexts to which scale-up occurs. Here, we describe Read It Again!, a 30-week curriculum supplement designed to enhance early educators' explicit teaching of early literacy skills. Designed for scalability, the open-source curriculum supplement…

More than two-thirds of middle school students do not read proficiently. Research has shown that targeted interventions using explicit instruction methods can improve reading outcomes for struggling readers. A central feature of explicit instruction is the systematic implementation of instructional interactions, but it is not clear what specific…

Explicit instruction is a high-leverage practice for special education and is associated with improved learning for students with disabilities (Hughes et al., 2019). The high-leverage practices are 22 critical practices in special education that are effective for improving outcomes for a broad range of students with and at risk for disabilities…

This study's purpose was to examine the effects of the concrete-representational-abstract integrated (CRA-I) sequence on the performance of students who struggled with rational number concepts. Three students in southeastern U.S. fifth grade class participated in the study. The CRA-I intervention was grounded in the principles of explicit…

In this systematic review, we examined interventions for increasing prosocial employment skills for adolescents with emotional and/or behavioral disorders (EBDs). Many studies have focused on social skills related to employment for individuals with intellectual disabilities or autism spectrum disorders. However, there is a paucity of research on…

This paper details a literature review of mathematics vocabulary intervention studies for students with mathematics difficulty. The primary aim was to identify instructional practices that support mathematics vocabulary development. We conducted a database search to identify mathematics intervention studies either focused exclusively on vocabulary…

We report on a school-based randomized control trial study comparing two morphological interventions with untaught controls: one focusing on direct instruction targeting print morphological decoding (direct decoding condition) and the other on inquiry-focused pedagogy using oral morphological analysis (inquiry-analysis condition). We identified 63…

An emerging body of research suggests that content-rich literacy instruction has the power to expand elementary children's domain-general and domain-specific literacy skills. For content teachers, such as science teachers, explicit instruction in disciplinary-language and literacy practices can support students reading and writing of school-based…

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…

In writing argumentative syntheses from multiple and contradictory sources, students must contrast and integrate different perspectives on a topic or issue. This complex task of source-based argumentation has been shown to be effective for learning, but it has also been shown to be quite challenging. Because of the challenges, educational…

We examined the efficacy of two interventions aiming to strengthen argumentative text comprehension in Greek secondary students with specific reading disability or low reading achievement of unspecified cause. The first intervention (control group, n = 29) was based on principles of systematic explicit instruction, whereas in the second one…

Researchers have repeatedly found schematic diagrams, both as part of Modified Schema Based Instruction and outside of this problem-solving approach, effective for teaching students with disabilities, including intellectual and developmental disabilities (IDD), to solve math word problems. The current study was a systematic replication of Bouck,…

It has been suggested for many years that students who are able to judge their own performance should do well in academic assessments. Despite the increasing number of empirical studies investigating the effect of self-assessment on academic performance, there has not been a recent synthesis of findings in the higher education context. The current…

Fraction competence is essential for learning algebra and pursuing careers in science, technology, engineering, and mathematics. However, many children have difficulty using fractions, especially those struggling with mathematics. In this study, we examined the effect of a Tier 2 multicomponent fraction intervention for fifth graders, using a…

Teachers and clinicians report feeling underprepared to implement evidence-based behavior supports. As such, effective models of professional development that lead to improved outcomes for all individuals are required. Critical components of high-quality professional development include explicit instruction, modeling, practice, direct feedback,…
