Mindfulness based interventions (MBIs) for teachers can improve classroom interactions, teacher mindfulness, and well-being, yet whether teacher focused MBIs also benefit children remains largely unexplored. This cluster randomized trial with 36 urban elementary schools, 224 K-5th grade teachers (M[subscript age] = 41.5) and 5200 children…

The goal of this randomized controlled trial (RCT) was to evaluate the effectiveness of a small-group intervention in fractions for fifth-graders who are performing below grade level in mathematics. The impact of the fractions intervention was assessed on fifth-grade at-risk students' understanding of foundational fractions concepts and procedural…

This study examined the effects of a small group intervention targeting paraphrasing and text structure instruction on the main idea generation and reading comprehension of students with reading disabilities in Grades 4 and 5. Students (N = 62) were randomly assigned to receive the Tier 2-type intervention or business-as-usual instruction.…

The main purposes of this study were to test the effects of teaching at-risk 4th graders to provide explanations for their mathematics work and examine whether those effects occur by compensating for limitations in cognitive processes. We randomly assigned 212 children to 3 conditions: a control group and 2 variants of a multicomponent fraction…

Purpose: The Santa Ana Unified School District received an i3 grant (Investing in Innovation; funded by the U.S. Department of Education Grant number U411C160074) to build on their existing school climate practices. Called the Enhanced Positive School Climate Model, the aim is to improve school climate, student-adult relationships, create social…

This article describes the effects of an analysis-of-practice professional development (PD) program on elementary school students' (Grades 4-6) science outcomes. The study design was a cluster-randomized trial with an analysis sample of 77 schools, 144 teachers and 2,823 students. Forty-two schools were randomly assigned to treatment, (88.5 hours)…

We examine the efficacy of an intervention to improve word reading and reading comprehension in fourth- and fifth-grade students with significant reading problems. Using a randomized control trial design, we compare the fourth- and fifth-grade reading outcomes of students with severe reading difficulties who were provided a researcher-developed…

This randomized control trial examined the efficacy of an intervention aimed at improving multisyllabic word reading (MWR) skills among fourth- and fifth-grade struggling readers (n = 109, 48.6% male), as well as the relative effects of an embedded motivational beliefs training component. This study was a closely aligned replication of our earlier…

Most U.S. classrooms serve students with various linguistic and academic needs. Tier-I universal approaches support English language learners (ELLs) without segregating them into a different track and thereby constraining future learning opportunities. The current study examines whether Word Generation (WG), a Tier-I discussion-based program…

This study investigated whether individual differences in working memory (WM) moderate effects of 2 variations of intervention designed to improve at-risk 4th graders' fraction knowledge. We also examined the effects of each intervention condition against a business-as-usual control group and assessed whether children's measurement interpretation…

The 2013 study, "Does Working Memory Moderate the Effects of Fraction Intervention? An Aptitude-Treatment Interaction," examined the impacts of the fluency and conceptual versions of "Fraction Face-Off!," a math instruction program designed to improve knowledge of fractions and decimals in fourth-graders at risk for low…

The purpose of this study was to assess whether intervention with an integrated focus on fraction and decimal magnitude provides added value in improving rational number performance over intervention focused exclusively on fractions. We randomly assigned 4th graders with poor whole-number performance to 3 conditions: a business-as-usual control…

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program to improve elementary students' vocabulary skills and reading comprehension. The study used a multi-site cluster randomized, experimental design, which randomly assigned 92 4th grade classrooms (n=2558 students) from two cohorts to a treatment or control…

The recent wave of test-based accountability reforms has negatively impacted the provision of K-12 arts educational experiences. Advocates contend that, in addition to providing intrinsic benefits, the arts can positively influence academic and social development. However, the empirical evidence to support such claims is limited. We conducted a…

The authors' purpose was to determine the effects of computer-based practice and conceptual interventions on computational fluency and word-problem solving of fourth- and fifth-grade students with mathematics difficulties. A randomized pretest-posttest control group design found that students assigned to the computer-based practice intervention…
