Evidence-based mathematics interventions are critical for supporting students with mathematics difficulties. In research and practice, collecting implementation fidelity is important for ensuring that all the core components of the intervention are implemented as designed. Historically, implementation fidelity has been defined as multi-faceted…

The Commonwealth of the Northern Mariana Islands Public School System requested a systematic review of Tier 2 literacy interventions for students in grades K-3. This review defines a Tier 2 literacy intervention as a supplemental instructional program for students who require support in addition to the Tier 1 core reading program. Of the 267…

The present study aimed to examine the effect of a dialogic book reading program on preschool children's perspective taking skills. In line with this aim, a dialogic book reading program was designed, and its effects were tested in a quasi-experimental study involving both pre/post and follow-up tests. The study group consisted of 42 five-year old…

This is the methodology appendix for the report, "The Conversion of Enrollment Slots from Head Start to Early Head Start (HS2EHS) Case Studies." It includes the following sections: (1) Sample; (2) Recruitment; (3) Data Collection; and (4) Analysis.

Behavioral interventions delivered in preschools can help young children who need support for their behavior. However, preschool teachers face barriers to implementing behavioral interventions, leading to a research-to-practice gap. To better understand how to support preschool teachers, we conducted a scoping review of determinants (i.e.,…

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…

This study assessed the effectiveness of the TRACK Rx program. Track Rx is a program for healthcare professionals to counsel and prescribe outdoor physical activity (PA) to children. The program was implemented by a school nurse to increase children's time spent outdoors, increase a child's nature-based PA, and increase parents' intention for…

Teacher consultation is commonly used to ensure that classroom-based interventions are implemented with fidelity to achieve targeted outcomes, yet the consultation process is not well-understood. Consultant-teacher relationship quality is one feature of consultation that may promote intervention outcomes--both directly and indirectly via teachers'…

Early childhood forms the fundamental basis for developing various social-emotional skills and represents a unique opportunity to lay the foundation for healthy development. Insensitive learning environments in early childhood may lead to social-emotional difficulties, increasing the risk of developing severe behavioral problems. However,…

There is limited research about Tier 3 interventions provided during typical school Response to Intervention (RTI) implementation. As part of a larger RTI exploration study designed to focus on students with the most intensive reading needs, our goal was to contrast their Tier 1 core reading instruction with their Tier 3 intervention. Schools…

Despite the recognized effectiveness of naturalistic intervention practices, including activity-based intervention (ABI), challenges remain regarding their implementation. Assessing implementation fidelity can help understand factors that may influence their implementation. This study aims to document the evolution of ABI implementation fidelity…

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.,…

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…

Implementation fidelity is often thought of as a necessary condition to achieve internal validity and as having a relation to student outcomes. This relation is increasingly modeled; we reviewed reading intervention studies for students in pre-K-12 in which measures of implementation fidelity were included in final data analysis. A systematic…

Educational attainment is recognised as the most influential social determinant of lifelong physical and mental health, and school engagement predicts later social, emotional and economic wellbeing. However, research has shown significant socio-economic status (SES)-based disparities across all key areas of early childhood development. The use of…
