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…

More research is needed to understand the effects of school-based mindfulness programs in the years before adolescence, which represent a critical juncture and transitional period of development. The present study investigated mindfulness with elementary school students using random assignment and objective measures. The sample included 292 5th…

Boys and girls sit together in most classrooms, but do they interact? Based on forty-year-old evidence, coeducational classes may not be coeducational but instead be segregated by gender, which may undermine student success. Our goal is to answer this question in today's classrooms. We used longitudinal data to assess gender segregation in 26…

This report summarizes the results of kindergarten through fifth grade students' academic achievement outcomes in mathematics and science following four years of campus-level participation in the Launching Elementary Academic Foundations (LEAF) to STEM program. The LEAF to STEM Program consists of three key components that were adapted for K-5…

Student motivation to write is a pivotal factor influencing their writing achievement. However, individual motivation to write is not independent of the learning environment. It also is crucial for teachers to develop their own efficacy, knowledge, and ability in writing and writing instruction to help them utilize effective instructional methods…

This study explores whether teacher reports of executive functions predict change in reading performance (i.e., reading development) for elementary-aged students when controlling for direct assessments of executive functions and for teacher reports of students' literacy skills. Prior research has raised problems with the construct validity of…

Recent reviews of automated writing evaluation systems indicate lack of uniformity in the purpose, design, and assessment of such systems. Our work lies at the nexus of critical themes arising from these reviews. We describe our work on eRevise, an automated writing evaluation system focused on elementary students' text-based evidence-use. eRevise…

This study's 1st purpose was to investigate effects of a 4th- and 5th-grade "next-generation" fraction intervention, which included 6 enhancements over a previously validated fraction intervention, designed to address Career- and College-Readiness standards. The next-generation intervention is referred to as "Super Solvers."…

Student behavior problems in general-education classrooms present a major barrier to effective teaching. Behavior challenges, such as disruptions, noncompliance, and peer conflicts, reduce instructional time, whereas prosocial behaviors, such as paying attention, being ready to work, asking for help, participating in class, and completing…

This study evaluated the feasibility of the Knowledge, Language, and Inquiry (K.L.I.) intervention, designed to support Grades 3-5 multilingual students classified as English learners (ML-ELs) in building content knowledge, language skills, and reading comprehension through inquiry-based small-group instruction. Feasibility was examined across…

Strategic and Interactive Writing Instruction (SIWI) involves teaching cognitive writing strategies and apprenticing novices within collaborative writing communities. It is responsive to deaf students' diverse language experiences through embedded metalinguistic/linguistic components. A randomized controlled trial of SIWI was conducted with 15…

A central goal of upper elementary schools is improving students' skills to write persuasively using source materials. This study focused on three essential areas of writing at the upper elementary grade levels. First, children learned skills to read and use source materials through the web-based intelligent tutoring system for the text structure…

Determining the effectiveness of core mathematics curricula is foundational to evidence-based practice. Examining effectiveness heterogeneity is also crucial to better understanding mathematics achievement among English language learners (ELLs). In this study, we used a quasi-experimental design (difference-in-differences) to examine the impact of…

Many studies conducted in the last decades report that very few elementary-grades students understand the meaning of = in mathematics, and that upper-elementary students do not understand it any better than the lower-elementary students do. Using data from thousands of Florida elementary students, we show that students in Florida perform ten to…

School-aged English Learners (ELs) are faced with the challenging task of acquiring a foreign language while simultaneously reading academically demanding literature. Therefore, the current research aimed to examine the relation between the rate of grammatical tense marking errors made by ELs and their performance on measures of reading…
