We present an aggregation scheme that increases power in randomized controlled trials and quasi-experiments when the intervention possesses a robust and well-articulated theory of change. Intervention studies using longitudinal data often include multiple observations on individuals, some of which may be more likely to manifest a treatment effect…

Students with early indicators of behavior risk have predictable, negative outcomes, and those with co-existing academic problems have significantly more negative outcomes. Identifying academic subclasses of students with behavior risk can inform integrated interventions and school-based problem-solving teams. In addition, identifying academic…

Well-designed mathematics instruction focused on concepts and problem-solving skills associated with measurement and data analysis can build a foundational understanding for more advanced mathematics. This study investigated the efficacy of the Precision Mathematics Level 1 (PM-L1) intervention, a Tier 2 print- and technology-based mathematics…

To support students' academic, behavioral, and social needs, many schools have adopted multitiered models of prevention. Because Tier 3 interventions are costly in terms of time and resources, schools must find efficient and effective Tier 2 interventions prior to providing such intense supports. In this article, we review the literature base on…

Total group contingencies, a variation of interdependent group contingencies, provide educators with an efficient and effective mechanism to improve social behavior and increase academic skills. Their utility has not been examined in small educational groups. This is unfortunate as supplemental instruction frequently is delivered in small group…

In this study, the authors explored the effect of prereading skills at the start of kindergarten and change in skills during kindergarten on response to Tier I (universal) Schoolwide Positive Behavior Support in Grade 5. A longitudinal data set of 473 students, including "Dynamic Indicators of Basic Early Literacy Skills" measures at the…

Preschool parent interventions may produce downstream benefits if initial intervention gains are sustained and improve later socialization experiences. This study explored associations between initial effects of the REDI (Research-based Developmentally Informed) Parent program and later benefits. A randomized trial involving 200 Head Start…

The evolution of multi-tier systems of support (MTSS) for both academics and behavior has reflected the diverse interests of those leading implementation efforts, the influence of various state and local regulatory requirements, and differing funding methods and priorities. These variations have naturally led to many different pathways for…

In today's educational environment, schools struggle to meet the academic needs of every student. Many schools are challenged by the use of a response-to-intervention framework in which too many students need strong interventions. This article details a data-driven, decision-making response-to-intervention reading team model in which teachers,…

The effects of a literacy intervention matching student skill level with academic performance demands were examined through a multiple baseline across participants design. The dual dependent variables were problem behavior and academic engagement. Four students in Grades 2 or 3 who exhibited low academic performance and problem behavior during…

Objective: To examine whether teacher reports of accommodations and interventions for inattentive first graders are consistent with best practice guidelines. Method: A total of 36 teachers completed the Teacher Management Questionnaire (TMQ) for 92 students in five predominantly low-income, minority schools. The TMQ is a newly developed measure…

As schools implement response to intervention to identify and serve students with learning difficulties, it is critical for educators to know how to evaluate screening measures. In the present study, "Dynamic Indicators of Basic Early Literacy Skills" Oral Reading Fluency was used to compare the differential decisions that might occur in…

This study examined the influences of problem behaviors on kindergarten reading outcomes and investigated the extent to which explicit, code-based reading instruction moderated those relations among 206 children identified as being at risk of reading difficulty. Children from the classrooms of 57 kindergarten teachers in 12 schools were randomly…

Reading difficulties and disabilities present serious and potentially lifelong challenges. Children who do not read well are more likely to be retained a grade in school, drop out of high school, become a teen parent, or enter the juvenile justice system. Building on the extant research and seminal studies, including the National Reading Panel and…

Response to Intervention (RTI) provides a challenge for schools to deliver appropriate and scientifically validated reading instruction to all students through a three-tier model. While many educators recognize the need for a strong core-reading program (Tier 1), interventions for Tier 2 and Tier 3 students remain more difficult to implement. We…
