In this study, we examined the extent to which teachers' treatment adherence, instructional quality, and the interaction of these variables influenced eighth-grade students' content knowledge and reading comprehension. We examined treatment fidelity for students (n = 775) in classes randomly assigned to receive an evidence-based content area…

Imagine Math® is a standards-aligned, adaptive, interactive online mathematics program designed to supplement in-class instruction for students. This evaluation report examined the fidelity of implementation of Imagine Math® and the associations between its use and student achievement in Houston Independent School District (HISD) secondary schools…

In this study, longitudinal data from 708 schools across five states in the continental United States were analyzed to measure the time between initial training and adequate implementation of Tier I Schoolwide Positive Behavioral Interventions and Supports over 5 years and the extent to which it varied by school characteristics. Results indicated…

This study documents the process of implementation of an adolescent reading intervention. Using data from observations of teachers (n=17) during the 2013-14 school year, I conducted a nuanced descriptive analysis of fidelity of implementation (FoI). I also analyzed weekly logs completed by literacy coaches (n=3) to examine variation in quantity…

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…

Despite its promise to help teachers meet the needs of diverse learners, district usage of Achieve3000® among most students with access to it remains far below the optimal level necessary for them to realize literacy growth and college and career readiness. Only a tiny minority of students (402 out of about 111,000) seem to be engaging Achieve3000…

This study examines predictors of abandonment of evidence-based practices through descriptive analyses of extant state-level training data, fidelity of implementation data, and nationally reported school demographic data across 915 schools in three states implementing school-wide positive behavioral interventions and supports (SWPBIS). Schools…

Purpose: The purpose of this study was to determine the acute dose-response relationship of classroom exercise breaks with executive function and math performance in 9- to 12-year-old children by comparing 5-min, 10-min, or 20-min classroom exercise breaks to 10 min of sedentary classroom activity. Method: This study used a within-subjects…

Using a modified system of least prompts, two classroom teachers taught three participants with moderate intellectual disability to generate questions about United States history. After reading brief portions of the text aloud to the participants, the teachers taught participants to identify if the answer to the question was in the book or not in…

This study is to examine if implementation of the universal level of PBS is related to student achievement on the LEAP and iLEAP examinations administered as part of the Louisiana Educational Assessment Program. A second purpose is to examine whether identified student/school characteristics contribute to any difference in academic performance. To…

Reading instruction for students with MoID is typically limited to sight-word instruction. We developed a 2-part, phonetic instructional sequence based upon Direct Instruction teaching methodology to teach students with MoID word-analysis skills that generalize to untaught words encountered in their environment. Elementary and middle-school…

The current study explored the extent to which a common measure of perceived implementation of critical features of School-wide Positive Behavior Support (SWPBS) predicted fidelity of implementation 3 years later. Respondents included school personnel from 261 schools across the United States implementing SWPBS. School teams completed the…

Using a single-subject reversal design, this study evaluated the use of a compare-contrast strategy on the ability of students with autism spectrum disorder to comprehend science text. Three middle school students with high-functioning autism and their teacher participated in this study. A content analysis comparing the number of meaning units in…

This study examines factors related to the sustainability of SimCalc Mathworlds (SCMW), a technology-infused mathematics curriculum. We surveyed middle school teachers one year after their participation in a randomized trial where they were introduced to SCMW curriculum, to identify factors related to their continued use of the materials in ways…
