We evaluated the effectiveness of Boston vs. Bullies, a short-term, free, bullying prevention program that uses celebrity athletes to present content. Fifth-grade students in 10 schools were randomized to either complete the Boston vs. Bullies intervention (n = 388), or to a wait-list control group (n = 266). Pre- and post-surveys assessed…

"INSPIRE" is an Investing in Innovation (i3) development grant funded by the Office of Innovation and Improvement, U.S. Department of Education. "INSPIRE" provides an innovative integrated K-12 STEM pipeline approach focused on STEM course content and instructional redesign. The INSPIRE model was implemented in Cabarrus County…

In recent years, the regression discontinuity design (RDD) has gained widespread recognition as a quasi-experimental method that when used correctly, can produce internally valid estimates of causal effects of a treatment, a program or an intervention (hereafter referred to as treatment effects). In an RDD study, subjects or groups of subjects…

Researchers have recently used traditional item response theory (IRT) models to measure mathematical knowledge for teaching (MKT). Some studies (e.g., Hill, 2007; Izsak, Orrill, Cohen, & Brown, 2010), however, have reported subgroups when measuring middle-grades teachers' MKT, and such groups violate a key assumption of IRT models. This study…

The goal of this paper is to use Knowledge Tracing to augment the results obtained from an experiment that investigated the effects of practice schedules using an intelligent tutoring system for fractions. Specifically, this experiment compared different practice schedules of multiple representations of fractions: representations were presented to…

The effects of a 20-session intervention targeting morphological word structure on vocabulary knowledge were investigated in four Grade 4 and 5 classes, assigned randomly to treatment and control conditions. Hierarchical regression analyses controlling for initial vocabulary showed significant instructional effects on morphological analysis and…

This paper describes an iteration of a design-based research project that involved integrating commercial physical activity data (PAD) sensors, such as heart rate monitors and pedometers, as technologies that could be used in two fifth grade classrooms. By working in partnership with two participating teachers and seeking out immediate resources…

A randomized controlled trial was used to evaluate the effects of a supplemental mathematics intervention that emphasized fluency building for computations and procedures. All fourth- and fifth-grade English-speaking students from a single school district who were participating in general education mathematics instruction and had a 2009 year-end…

The McKinney-Vento Homeless Education Assistance Improvements Act of 2001 (MCKV), which provides funds to local educational agencies (LEAs), is almost a decade old, yet no evaluations of its academic effectiveness have been reported. Using a systems theory framework, the authors answer the question of whether homeless students in grade 6 from LEAs…

As part of a diagnosis and tutoring project in an elementary education reading course, a pre-service teacher was encouraged to use an iPad as the vehicle for intervention strategies with a fifth grade struggling reader with Attention Deficit Hyperactivity Disorder. The device not only helped the student focus attention, it facilitated his becoming…

The present study explored the effects of a mediated intervention programme on a sample of Grade 5 learners, in a remedial school. The participants (n = 20) were systematically sampled and they constituted two groups; namely, Individual Mediation (n = 10) and Group Mediation (n = 10). It was hypothesised that participants exposed to this programme…

This study explores the relationship between teacher knowledge and student learning in the area of mathematics by developing and evaluating an innovative approach to assessing teacher knowledge. This approach is based on teachers' analyses of classroom video clips. Teachers watched 13 video clips of classroom instruction and then provided written…

This study advances research on media literacy by comparing the effectiveness of two versions of a media literacy intervention over time. Participants (156 children in 4th or 5th grade) were randomly assigned to one of two treatment groups or a control group. Both treatment groups were exposed to an instructional intervention designed to reduce…

Can an electronic portfolio that is both a multimedia container for student work and a tool to support key learning processes have a positive impact on the literacy practices and self-regulated learning skills of students? This article presents the findings of a yearlong study conducted in three Canadian provinces during the 2007-2008 school year…

This study investigated the effects of different versions of Web-based instruction focused on text structure on fifth- and seventh-grade students' reading comprehension. Stratified random assignment was employed in a two-factor experiment embedded within a pretest and multiple posttests design (immediate and four-month delayed posttests). The two…
