Understanding how to intensify an intervention is critical to implementing response-to-intervention (RtI), a tiered, problem-solving framework to deliver evidence-based interventions per student needs. Research and practice guidelines provide conflicting recommendations for delivering math interventions (i.e., treatment intensity) within RtI. The…

Fraction knowledge is an essential building block for successful completion of advanced mathematics courses and linked to the development of algebraic understanding. Many students, especially those with disabilities, experience significant difficulties developing fraction knowledge. Intensive fraction interventions have been shown to be effective…

With high stakes testing in public schools, pressure for success prompts schools to implement intervention programs for reading and mathematics, often at the expense of extra-curricular and elective activities. Previous literature indicated a correlation between reading comprehension and mathematical understanding. This study examined the specific…

CBM for mathematics assesses growth in accuracy and fluency of basic math skills using content from a student's curriculum. CBM for mathematics can include single-skill measures (SSM), skill-based measures (SBM), and general-outcome measures (GOM). Past research on growth rates in CBM for mathematics has focused on GOMs and has relied on…

This study investigated whether mathematics education based on a multi-tiered response to intervention (RTI) model can support students' arithmetic competence in primary schools in Sweden. The intent was to identify and support students at risk of failure. In this study, 113 students participated in the intervention, and 30 students participated…

Treatment acceptability is an aspect of social validity that refers to participants' beliefs and perceptions about the intervention, such as the helpfulness of the strategies or the interventions' efficacy to improve performance. The purpose of this study was to conduct a systematic review of treatment acceptability measures administered during…

Although mathematics development research has become more prominent in the school psychology literature in recent years, a large research gap in this area exists regarding English language learners (ELLs). Significant research in education, cognitive science, and psychology has been devoted to understanding the links between language and…

Data from 403 third graders were analyzed to determine relative and combined efficacy of group-administered Curriculum-Based Measures (CBMs) and Teacher Rankings of student reading and math performance taken early in the school year to predict end-of-year achievement scores. Teacher Rankings added to the power of CBMs to predict reading (R2 change…

The purpose of this study was to determine if implementing a mathematics response-to-intervention program increases student achievement on the State of Texas Assessments of Academic Readiness mathematics test among fourth-grade students. The goal of this study was to determine if implementation leads to increased student performance among the…

The purpose of this study was to determine if students who scored in the lower percentiles range (1st to 10th) on the spring 2017 NWEA MAP assessment obtained a post ADDITION 1 score in BlueStreak Math during the 2017-18 school year had higher observed growth in RIT scores than students who scored in the lower percentiles ranges but did not obtain…

This study examined the role of initial skill in moderating intervention effects of a 50 lesson mathematics intervention program, ROOTS, for at risk kindergarten students focused on developing whole number concepts and skills. The study utilized a randomized block design with at-risk students (n = 592) within classrooms (n = 60) randomly assigned…

This dissertation reports the results of a research project that examined the effects of varying rates of reinforcement on students' math performance and assignment preference. The relationship between students' instructional level and the rate of reinforcement threshold for influencing assignment preference was also explored. Participants were…

In a response to intervention RtI paradigm, the use of brief experimental analyses (BEAs) for identifying effective interventions for elementary and middle school students struggling with math is a relatively new area of research. This investigation includes two studies, both of which employed a brief multielement design and an extended analysis…

This study examined the role of initial skill in moderating intervention effects of a 50-lesson mathematics intervention program, ROOTS, for at-risk kindergarten students focused on developing whole-number concepts and skills. The study utilized a randomized block design with at-risk students (n = 592) within classrooms (n = 60) randomly assigned…

Data from a large-scale math intervention program were used to evaluate the degree to which implementation fidelity (IF) and interventionist content knowledge were associated with student outcomes. Data were available for 33 interventionists serving 658 students in Grades 4-6 across one school year. A series of multilevel models were fit to the…
