The purpose of this longitudinal study was to examine patterns in implementation of Tiers 2 and 3 school-wide positive behavioral interventions and supports (SWPBIS) systems to identify timings of installation that led to higher implementation of advanced tiers. Extant data from 776 schools in 27 states reporting on the first 3 years of Tier 2…

In this 3-year prospective study, we tested the extent to which school-, practice-, and district-level variables predicted sustained implementation for schools in various stages of implementation of school-wide positive behavioral interventions and supports (SWPBIS) Tier 1 (universal) systems. Staff from 860 schools in 14 U.S. states completed a…

MathForward™, developed in 2004-2005 in cooperation with the Richardson (TX) Independent School District, was implemented nationwide in 2007. The program integrates TI technology and professional development while focusing on student achievement and teacher efficacy. This study investigated the effect of the MathForward™ program on student…

A critical aspect of intervention research is investigating the active ingredients that underlie intensive interventions and their theories of change. This study explored the rate of instructional interactions within treatment groups to determine whether they offered explanatory power of an empirically validated Tier 2 kindergarten mathematics…

Research suggests effective professional learning communities (PLCs) enhance teacher collaboration and student achievement. Some studies indicate that these communities also predict greater collective efficacy, while others suggest teacher efficacy is predictive of teachers working together. Although studies have identified effective,…

Schools are recognized as one of the most important settings for promoting social and emotional well-being among children and adolescents. This clustered randomized controlled trial evaluated Zippy's Friends, an international school-based emotional well-being programme, with 766 children from designated disadvantaged schools. The purpose of this…

This study examined the effects of a 10 week invented writing program with five-year-old preschoolers (mean age 5.7 years) on their immediate post intervention literacy skills and also the facilitative effects of the intervention on the subsequent learning to read during the first 6 months of schooling. The study included 105 children (54 girls)…

A 2-year, randomized control trial with 9th to 10th grade students with significant reading problems was provided for 50 minutes a day in small groups. Comparison students were provided an elective class and treatment students the reading intervention. Students were identified as demonstrating reading difficulties through failure on their state…

This randomized controlled field trial examined the efficacy of the Responsive Classroom (RC) approach on student achievement. Schools (n = 24) were randomized into intervention and control conditions; 2,904 children were studied from end of second to fifth grade. Students at schools assigned to the RC condition did not outperform students at…
