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…

Training teachers in evidence-based practice is a societal challenge. We conducted practical action research to investigate the impact of a professional development programme (the aim of which is to train teachers in explicit instruction) established according to the principles of effective professional development on one teacher's practices. A…

There is an apparent need to identify resource- and time-efficient approaches to supporting teacher implementers of behavioral interventions. The purpose of this study was to evaluate the effectiveness of a brief training and intermittent performance feedback coaching model on teacher implementation of a multicomponent behavioral intervention.…

The problem that prompted this qualitative case study was a continuous below proficiency level performance of the kindergarten through second-grade students in a U.S. Southern state in reading, despite response to intervention (RTI) being implemented since 2011. The purpose of the study was to explore K-2 teachers' perceptions regarding the…

Information about program implementation provides critical information for the interpretation of results from randomized trials. The present study provides an evaluation of the implementation of a Cognitively Guided Instruction mathematics teacher professional development as part of a large scale randomized controlled trial with teachers in first-…

In 2019, declines in reading achievement across Texas motivated changes for teacher recertification, which required 60-hour professional development in the science of teaching reading (STR). The problem this study addressed was the challenges K-Grade 3 reading teachers encountered when implementing the recently adopted Reading Academy content at a…

Punitive disciplinary approaches have been used for decades in primary grades with little improvement in behavior and negative impacts on classroom climate. This qualitative case study explored the perspectives of administrators and educators implementing restorative practice (RP) with fidelity in the primary grades of urban public elementary…

This study examines the effectiveness of scaling up a vocabulary intervention, pre-K-first grade, using a structured adaptation of the World of Words that allowed teachers some autonomy over its implementation. The purpose was to determine whether such an adaptation could maintain fidelity and promote positive child outcomes. Classrooms (pre-K…

The main objective of this study was to evaluate the efficacy of a Tier 2 intervention within the context of the Response to Intervention (RtI) model implemented by Spanish first- to second-grade primary school teachers to improve at-risk students' transcription skills. Teachers were instructed in the administration of a writing curriculum-based…

This study examined the role of fidelity in the reading outcomes within a Tier 2 intervention implemented by Spanish kindergarten and first grade school teachers. For this purpose, differences in reading performance growth were analyzed among at-risk students who received a Tier 2 intervention with high fidelity, at-risk students who received the…

This study uses implementation fidelity data from PreK to 1st grade in the Boston Public Schools (BPS) to measure instructional alignment and examine whether stronger alignment is associated with sustained benefits of BPS PreK on children's language, literacy, and math skills through first grade. The study includes N = 498 students (mean age =…

Evidenced-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…

This study examined teachers' adherence to the language of instruction in dual language education (DLE) programs among teachers in 19 kindergarten through 3rd grade Spanish-English two-way DLE immersion classrooms (n = 5, 90/10 model; n = 14, 50/50 model). Teachers were observed toward the beginning and end of the school year to determine…

Several school districts in Georgia use two teacher-administered diagnostic assessments of student knowledge of mathematics as part of their multi-tiered system of support in grades K-8: the Global Strategy Stage (GloSS; New Zealand Ministry of Education, 2012) and the Individual Knowledge Assessment of Number (IKAN; New Zealand Ministry of…

This document are the appendixes for the report, "The Reliability and Consequential Validity of Two Teacher-Administered Student Mathematics Diagnostic Assessments." Rather than relying on occasional testimonials from the field, decisions about using diagnostic assessments across the state should be based on psychometric data from an…
