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…

This study examined the effect of comprehension strategy instruction on third-grade English Learners' word-problem-solving performance. The supplemental intervention included modeling how to read the word problem to identify and restate the question, distinguishing relevant from irrelevant information, and collaborating with peers on applying the…

Using a randomized controlled trial, we examined the effect of a fractions intervention for students experiencing mathematical difficulties in Grade 5. Students who were eligible for the study (n = 205) were randomly assigned to intervention and comparison conditions, blocked by teacher. The intervention used systematic, explicit instruction and…

This study's first purpose was to investigate effects of a fourth- and fifth-grade "next-generation" fraction intervention, which included six enhancements over a previously validated fraction intervention, designed to address career- and college-readiness standards. The study's second purpose was to assess effects of the next-generation…

(1) Background: The response to intervention (RtI) model makes possible the early detection of reading problems and early intervention for students at risk. The purpose of this study is to analyze the effective measures that identify struggling readers and the most effective practices of the RtI model in reading in Primary Education. (2) Method: A…

This study's 1st purpose was to investigate effects of a 4th- and 5th-grade "next-generation" fraction intervention, which included 6 enhancements over a previously validated fraction intervention, designed to address Career- and College-Readiness standards. The next-generation intervention is referred to as "Super Solvers."…

This study explored the impact of a supplemental reading intervention delivered in English in Grade 1 on the performance of at-risk children educated in French Immersion schools. The intervention contrasted "Direct Mapping and Set-for-Variability" with a "Common and Best Practices" taught control condition in a matched…

This study explored the effects of an evidence-based literacy program, ABRACADABRA, on the spelling abilities of children with autism spectrum disorder (ASD). Twenty children with ASD aged 5-11 years were assigned to matched instruction and waitlist control groups. Children in the instruction group received 26 hrs of individualized, home-based…

The purposes of this study were to (a) explore whether early fractions understanding at 4th grade is differentially challenging for students with versus without adequate whole-number competence and (b) identify specific whole-number skill associated with difficulty in fractions understanding. Based on initial whole-number competence, 1,108 4th…

The purposes of this study were to assess the effects of fractions intervention for students who are at risk for poor outcomes and to examine whether a component that combines self-regulated learning with growth-mindset instruction (SR-GM) provides added value for improving outcomes. At-risk students (N = 84) were randomly assigned to three…

The study has two primary purposes. The first was to examine the efficacy of the "Super Solvers" Fractions Intervention (SSFI) for third-grade students at risk for mathematics learning disabilities (MLD). The second was to test the added value of embedding self-regulation instruction into the SSFI. Students were randomly assigned to a…

The purposes of this study were to assess the effects of fractions intervention for students who are at-risk for poor outcomes and to examine whether a component that combines self-regulated learning with growth mindset instruction (SR-GM) provides added value for improving outcomes. At-risk students (N = 84) were randomly assigned to 3…

The purposes of this study were twofold. The first was to test the efficacy of two versions of the "Super Solvers" (SS) intervention for fourth- and fifth-grade students at-risk for mathematics learning disabilities (MLD). The second was to test the value of adding an error analysis component to the SS intervention. Students were…

The purpose of this project evaluation was to assess the impact of data-based individualization (DBI) on the mathematics achievement of students with intensive mathematics learning needs, including students with disabilities. The evaluation study used a cluster randomized trial in which elementary schools were randomly assigned to treatment using…

Recent studies have proposed developments to the Simple View of Reading to reflect reading development across age groups and differences among learner profiles and account for additional factors that explain reading comprehension performance beyond word recognition and language comprehension. One of these proposals is the inclusion of cognitive…
