We investigated whether individual differences in overall receptive vocabulary knowledge measured at the beginning of the year moderated the effects of a kindergarten vocabulary intervention that supplemented classroom vocabulary instruction. We also examined whether moderation would offset the benefits of providing Tier-2 vocabulary intervention…

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…

Supporting the reading comprehension and content knowledge acquisition of English language learners (ELs) requires instructional practices that continue beyond developing the foundational skills of reading. In particular, the challenges ELs face highlight the importance of teaching reading comprehension practices in the middle grades through…

Thirty-two students enrolled in one of four sixth-grade classrooms across two elementary schools participated in this study. Students receiving supplemental and intensive instruction in math and those with math-related disabilities were participants. A treatment and control, pre/postexperimental design was used to examine the effect of preteaching…

This study evaluated the effects of a cross-age peer learning program targeting vocabulary and comprehension in kindergarten and fourth-grade classrooms with substantial proportions of English Learners (ELs). The study followed a quasi-experimental design with 12 classrooms (6 kindergarten and 6 fourth grade) in the intervention group and 12…

The purpose of this study was to support teachers' child-directed language and student outcomes by enhancing the educative features of an intervention targeted to vocabulary, conceptual development and comprehension. Using a set of design heuristics (Davis & Krajcik, 2005), our goal was to support teachers' professional development within the…

The purpose of this closely aligned conceptual replication study was to investigate the efficacy of a Tier 2 kindergarten mathematics intervention. The replication study differed from the initial randomized controlled trial on three important elements: geographical region, timing of the intervention, and instructional context of the…

This study investigated: 1) the influence of alphabet instructional content (letter names, letter sounds, or both) on alphabet learning and engagement of English only and dual language learner (DLL) children, and 2) the relation between children's initial status and growth in three underlying cognitive learning processes (paired-associate,…

This randomized control trial examined the efficacy of team-based learning implemented within 11th-grade social studies classes. A randomized blocked design was implemented with 26 classes randomly assigned to treatment or comparison. In the treatment classes teachers implemented team-based learning practices to support students in engaging in…

A cluster randomized trial estimated the effects of a supplemental vocabulary program, Elements of Reading[R]: vocabulary on student vocabulary and passage comprehension in moderate- to high-poverty elementary schools. Forty-four schools participated over a period spanning 2 consecutive school years. At baseline, 1,057 teachers and 16,471 students…

Reading comprehension in the content areas is a challenge for many middle grade students. Text structure-based instruction has yielded positive outcomes in reading comprehension at all grade levels in small and large studies. The text structure strategy delivered via the web, called Intelligent Tutoring System for the Text Structure Strategy…

A multi-cohort cluster randomized trial was conducted to estimate effects of rich vocabulary classroom instruction on vocabulary and reading comprehension. A total of 1,232 fourth- and fifth-grade students from 61 classrooms in 24 schools completed the study. Students received instruction in 140 Tier Two vocabulary words featured in two…

This article describes a randomized evaluation of The Reading Edge, a reading program for middle school students. The Reading Edge was designed to integrate findings of research on cooperative learning and metacognitive reading strategies into a replicable reading instructional package that could be implemented effectively in Title I middle…

Students' beliefs that success in science depends on exceptional talent negatively impact their motivation to learn. For example, such beliefs have been shown to be a major factor steering students away from taking science and math courses in high school and college. In the present study, we tested a novel story-based instruction that models how…

A multisite cluster randomized trial was conducted to examine the effects of the Social Skills Improvement System Classwide Intervention Program (SSIS-CIP; Elliott & Gresham, 2007) on students' classroom social behavior. The final sample included 432 students across 38 second grade classrooms. Social skills and problem behaviors were measured…
