This dissertation explores conceptual and methodological issues related to measuring implementation in quantitative educational research. Implementation, defined as the enactment of interventions in educational contexts, plays a pivotal role in understanding how programs operate and affect student outcomes. Despite its importance, there is…

As the most common setting where youth access behavioral healthcare, the education sector frequently employs training and follow-up consultation as cornerstone implementation strategies to promote the implementation of evidence-based practices (EBPs). However, these strategies alone are not sufficient to promote desirable implementation (e.g.,…

Guided by an interpretivist paradigm, the qualitative case study reported on here provided insight into the points of view of 9 foundation phase teachers on whether they believed that Response to Intervention (RtI) could be a viable approach to implement within their own school context. A semi-structured, focus group interview was conducted to…

Multi-tiered Systems of Support (MTSS) is an outgrowth of Response to Intervention (RtI). The various systems of support for students and school communities provided through these programs are integral to modern education and embedded in the Individuals with Disabilities Education Improvement Act (IDEIA) of 2004. While there are many benefits to…

The evolving educational landscape of our students' needs post-Covid has highlighted that student response to intervention must be of concern to all educators. Our student population has experienced an event that is like no other in our shared educational histories and our response to the aftermath of this event and how we assist students who are…

High-quality Tier 1 instruction is frequently conceptualized as the "foundation" for other tiers of intervention within multitiered systems of support (MTSS) models. However, the vast majority of Tier 2 intervention studies do not account for Tier 1 variables when examining intervention effectiveness. The purpose of this study was to…

High-quality Tier 1 instruction is frequently conceptualized as the "foundation" for other tiers of intervention within multi-tiered systems of support (MTSS) models (Gersten et al., 2009). However, the vast majority of Tier 2 intervention studies do not account for Tier 1 variables when examining intervention effectiveness (Hill et al.,…

Project START (Students and Teachers Actively Reading Together) is an adaptive shared reading intervention designed to address the varied learning needs of preschool children with autism spectrum disorder (ASD). This report summarizes procedures and results of the developmental year of the project, which focused primarily on evaluating…

This brief examines California's Multi-Tiered System of Supports (MTSS), which is a framework designed to identify and assist students performing below grade level. MTSS involves at least three tiers of support; Tier 2 includes personalized assistance. Unfortunately, Tier 2 services are not adequately resourced so it is not surprising that…

Promising findings from controlled research studies often fail to be transferred to and implemented in schools successfully. This problem is particularly apparent when considering implementation of evidence-based practices related to complex systems such as response to intervention (RTI) and other multitiered intervention frameworks in…

Response to Intervention (RTI) programs are designed to support students at risk of failing in school due to academic or behavioral problems. When RTI programs are applied inconsistently due to teachers' resources or knowledge, students may be wrongly identified for special education services. The purpose of this qualitative bounded descriptive…

For multi-tiered systems of support, such as Response-to-Intervention and Positive Behavior Interventions and Supports, to effectively impact student outcomes, interventions delivered across the tiers must be implemented as planned (i.e., with adequate treatment integrity). However, research suggests that most school personnel struggle to deliver…

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…

The purpose of this study is to ascertain the essential elements of Response to Intervention programs among 150 high performing Title I schools with high rates of poverty as measured by free/reduced lunch participation rates. Response to Intervention (RTI) is a nationally-known instructional model used to assist students who are struggling to…
