In this study, the relationship between differentiated instruction, as an element of data-based decision making, and student achievement was examined. Classroom observations (n = 144) were used to measure teachers' differentiated instruction practices and to predict the mathematical achievement of 2nd- and 5th-grade students (n = 953). The…

Although high-quality early educational environments are thought to be related to the growth of children's skills in mathematics, relatively little is known about specific aspects of classroom instruction that may promote these abilities. Data from a longitudinal investigation were used to investigate associations between teachers' language while…

This study evaluated the efficacy of Accelerated Reader, a computer-based learning program, at improving student reading. Accelerated Reader is a progress-monitoring, assessment, and practice tool that supports classroom instruction and guides independent reading. Researchers used a randomized controlled trial to evaluate the program with 344…

This study investigated the relationship between elementary classroom (N = 50) reading activities in Year 1 and reading performance (i.e., passage comprehension, letter-word identification, and word attack) 1 year later for English language learners (ELLs; N = 270). A cross-classification hierarchical model indicated that compared to other reading…

We examined the direct impact of an ongoing, intensive, and structured professional development (PD) within an English-as-second-language (ESL) instructional intervention on (a) teachers' time allocation in cognitive--academic language proficiency (CALP) and (b) Spanish-speaking English language learners' (ELLs) CALP development from the second to…

First Step to Success (First Step; Walker et al., 1997, 1998) is a secondary-level intervention for students with behavior problems in early elementary school. The purposes of this study were to assess whether effects in student behavior and academics at posttest shown in a recent efficacy trial (Walker et al., 2009) were maintained at follow-up…

Informed by research on interpersonal perception, peer relationships, and classroom climate, this study examines predictors of children's agreement with classmates on their classroom social networks. Social network data, peer nominations of positive behavior, and classroom observations were collected from 418 second-grade to fourth-grade children…

High-stakes tests are the most heavily weighted measures in accountability systems developed in response to No Child Left Behind. While some studies show high-stakes accountability being related to test score gains, others suggest these policies do not improve achievement and often result in unintended consequences. To understand mechanisms…
