The goal of the current study is to examine the degree to which measures of quality of implementation and student engagement moderate pretest--posttest changes in mediating variables that are targeted by DARE "keepin' it REAL." DARE officers (10 elementary school, five middle school) taught DARE "keepin' it REAL lessons to 1,017…

K-12 intervention studies often include fidelity of implementation (FOI) as a mediating variable, though most do not report the validity of fidelity measures. This article discusses the critical need for validated FOI scales. To illustrate our point, we describe the development and validation of the Implementation Validity Checklist (IVC-R), an…

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…

Numerous classroom-based interventions have aimed to improve sexual health outcomes for young people, yet few have shown strong, lasting effects. Ecological approaches that address multiple levels of a young person's environment offer largely untapped potential to positively change sexual behaviour. This paper presents results of a…

Collaborative Strategic Reading (CSR) is a set of research-based strategies designed to improve reading comprehension, enhance students' content area learning, facilitate access to higher-level texts, and to promote student engagement. The present study examines how fidelity of implementation of CSR is associated with reading outcomes for students…

The Technology Immersion Pilot (TIP), created by the Texas Legislature in 2003, was based on the assumption that the use of technology in Texas public schools could be achieved more effectively by "immersing" schools in technology rather than by introducing technology resources, such as hardware, software, digital content, and educator…

The Technology Immersion Pilot (TIP), created by the Texas Legislature in 2003, set forth a vision for technology immersion in public schools. Senate Bill 396 called for the Texas Education Agency (TEA) to establish a pilot project to "immerse" schools in technology by providing a wireless mobile computing device for each teacher and…

The Technology Immersion Pilot (TIP) sets forth a vision for technology immersion in Texas public schools. The Texas Education Agency (TEA) originally directed more than $14.5 million in federal Title II, Part D monies toward funding a wireless learning environment for high-need middle schools through a competitive grant process. A concurrent…

The Technology Immersion Pilot (TIP) sets forth a vision for technology immersion in Texas public schools. The Texas Education Agency (TEA) directed nearly $14 million in federal Title II, Part D monies toward funding a wireless learning environment for high-need middle schools through a competitive grant process. A concurrent research project…
