How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

School safety and crisis prevention, preparedness, and response initiatives have become standard operating procedures in schools throughout the USA. PREPaRE, a comprehensive curriculum developed by school-employed mental health professionals for school-based safety and crisis response teams, has been adopted by many schools in support of such initi...
Examining the use of conceptual frameworks such as the instructional hierarchy (IH) to drive academic interventions represents an important area of inquiry in order to understand why an intervention was effective. However, to date, the IH has only been examined retroactively to explain the effectiveness of math interventions and has not been used t...
Evidence-based interventions exist for improving multiple fundamental math competencies, but delivering interventions with fidelity and within a data-driven, tiered framework is a practical challenge faced by most schools. The current study evaluated a math intervention program delivered with community-based resources via AmeriCorps. At the beginni...
The amount of information that students successfully learn and later recall from each intervention session is limited and is called the acquisition rate (AR). Research has consistently supported the effects of modifying intervention set sizes with AR data, but research with AR is in its infancy. The current study compared the relationship between A...
Incremental rehearsal (IR) is an intervention with demonstrated effectiveness in increasing retention of information, yet little is known about how specific intervention components contribute to the intervention's effectiveness. The purpose of this study was to further the theoretical understanding of the intervention by comparing the effects of op...
Incremental rehearsal (IR) is a highly effective intervention that uses high repetition and a high ratio of known to unknown items with linearly spaced known items between the new items. It has been hypothesized that narrowly spaced practice would result in quick learning, whereas items that are widely spaced would result in longer-term retention....
The purpose of the current study was to evaluate the importance of growth in math fact skills within the context of overall math proficiency. Data for 1,493 elementary and middle school students were included for analysis. Regression models were fit to examine the relative value of math fact fluency growth, prior state test performance, and a fall...
Ecological systems theory (EST) has been suggested as a framework to provide effective school psychology services, but previous reviews of research found questionable consistency between methods and the principles of EST. The current article reviewed 349 articles published in School Psychology Review (SPR) between 2006 and 2015 and compared the met...
Incremental rehearsal (IR) has consistently led to effective retention of newly learned material, including math facts. The number of new items taught during one intervention session, called the intervention set, could be used to individualize the intervention. The appropriate amount of information that a student can rehearse and later recall durin...
This purpose of this study was to examine the reliability and validity of a curriculum-based measure of word problem solving (CBM-WPS) as an indicator of performance and progress in a sample of 136 third-grade students at risk for mathematics difficulties (MDs) instructed in a standards-based mathematics curriculum. Students completed the CBM-WPS m...
This study compared the effects of delivering a supplemental, small-group tutoring intervention on the mathematics outcomes of third-grade students at risk for mathematics difficulties (MD) who were randomly assigned to either a schema-based instruction (SBI) or control group. SBI emphasized the underlying mathematical structure of additive problem...
This study examined the quality of the research base related to strategy instruction priming the underlying mathematical problem structure for students with learning disabilities and those at risk for mathematics difficulties. We evaluated the quality of methodological rigor of 18 group research studies using the criteria proposed by Gersten et al....
This intervention study compared the efficacy of small-group tutoring on the mathematics learning of third-grade students at risk for mathematics difficulty using either a school-provided standards-based curriculum (SBC) or a schema-based instruction (SBI) curriculum. The SBI curriculum placed particular emphasis on the underlying mathematical stru...
The current study meta-analyzed single-case design (SCD) and group research regarding incremental rehearsal (IR). We used phi to meta-analyze data from 19 IR studies. Data from the SCD studies resulted in a nonoverlap of all pairs (NAP) score of 98.9 % (95 % CI = 97.6–100 %), which resulted in a weighted phi of .77 (95 % CI = .69–.83). The group re...
Kindergarten Peer Assisted Learning Strategies and directly teaching and reinforcing behavioral expectations are empirically supported interventions for building early literacy skills and increasing on-task behavior, respectively. Previous research has not investigated the application of both academic and behavior interventions simultaneously to pr...
The profound consequences of early reading failure necessitate the provision of early literacy interventions to struggling readers. Many schools struggle, however, to address early reading difficulties because of insufficient human resources. Accordingly, the present study investigated the effectiveness of incremental rehearsal (IR) as a Tier 3 int...
The current article reviews research published in Assessment for Effective Intervention during the past 3 years. A total of 57 research articles were published during that period, with a current rejection rate of approximately 78%. A close examination of the pool of articles revealed seven overarching themes: behavioral assessment tools, group diff...
