The present article considers a fundamental question in evaluation research: "By how much do program effects vary across sites?" The article first presents a theoretical model of cross-site impact variation and a related estimation model with a random treatment coefficient and fixed site-specific intercepts. This approach eliminates…

Recent studies suggest that the number of students pursuing science, technology, engineering, and mathematics (STEM) degrees has been generally decreasing. An extensive body of research cites the lack of motivation and engagement in the learning process as a major underlying reason of this decline. It has been discussed that if properly…

We conducted a potential efficacy trial examining the effects of classroom-wide implementation of the "Pyramid Model for Promoting Young Children's Social-Emotional Competence" on teachers' implementation of "Pyramid Model" practices and children's social-emotional skills and challenging behavior. Participants were 40 preschool…

Although learning mathematics certainly depends upon accurate understanding of the facts of multiplication, it requires much more.

The children appreciated…

A widely cited meta-analysis of the effects of comprehensive school reform and student achievement (Borman, Hewes, Overman, and Brown, 2003) found Modern Red Schoolhouse-developed whole-school intervention programs to boost student achievement outcomes at rates on par with or higher than other comprehensive school reforms such as "America's…

With this point in mind, the present study addressed the question of whether student vocabulary acquisition could be accelerated by using a multi-part, semantic word-family-oriented learning strategy to…

In the present study, we investigated critical factors in letter-sound acquisition (i.e., letter-name knowledge and phonological awareness) with data from 653 English-speaking kindergartners in the beginning of the year. We examined (a) the contribution of phonological awareness to facilitating letter-sound acquisition from letter names and (b)…

This study examined the components of a one-on-one literacy tutoring model to identify the necessary and sufficient elements for helping struggling beginning readers. The tutoring components of interest included word work using manipulative letters, written word work, and a generalization component. Reading assessment data from 100 first-grade…

Stressful life events are an important risk factor for psychopathology among children and adolescents. However, variation in life stress may be both stable and time-varying with associated differences in the antecedents. We tested, using latent variable modeling, a state-trait model of stressful life events in adolescence, and predictors of…

The aim of this study was to compare the acquisition of the van Hiele levels of sixth-grade students engaged in instruction using a reform-based curriculum with sixth-grade students engaged in instruction using a traditional curriculum. There were 273 sixth-grade mathematics students, 123 in the control group and 150 in the treatment group,…
