Researchers use data from the RAND American Mathematics Educator Study surveys of public school principals and teachers to investigate three school structures--referred to as "school opportunity structures" throughout this report--that may affect kindergarten through 8th grade (K-8) students' mathematics learning. These structures are…

Lesson study, especially when conducted with support from targeted resources, is often identified as a potentially effective means to support teacher learning. In this study, 80 school-based teams of educators, representing 80 classrooms of third- or fourth-grade students in the US, were randomly assigned to one of four conditions: lesson study…

In the U.S., state guidance to schools in response to the COVID-19 pandemic was politicized. We used state-level political affiliation to explore whether access to curricular resources differed pre-pandemic or during pandemic remote teaching and teachers' reported control over curricular resources during pandemic teaching. We found that…

The current brief provides an overview of the 2021-2022 school year student-to-school psychologist ratio for every United States territory, using the National Center for Education Statistics (NCES) counts of school psychologists. In addition to this, data are presented on the percentage change in student-to-school psychologist ratio from the…

We present findings across three randomized trials of "Descubriendo la Lectura" (DLL), an intervention designed to improve literacy skills of Spanish-speaking first graders struggling with reading. DLL is a one-to-one Spanish-language literacy program lasting 12-20 weeks offered to a school's lowest performing emerging bilingual first…

Purpose: Our purpose was to gather and evaluate accurate, up-to-date information on physical education (PE) policy implementation across multiple U.S. states and regions. Methods: A U.S. Physical Education and Physical Activity Policy questionnaire was developed and completed by 4,845 public-school PE teachers from 25 U.S. states. The U.S.…

Since 2017, over 300 presidentially-declared major disasters have occurred across all 50 states and all U.S. territories. Many of these disasters have had devastating effects on K-12 schools, including those in socially vulnerable communities for whom disaster recovery is more challenging. The Additional Supplemental Appropriations for Disaster…

Background: This study describes a method for harmonizing data collected with different tools to compute a rating of compliance with national recommendations for school physical activity (PA) and nutrition environments. Methods: We reviewed questionnaire items from 84 elementary schools that participated in the Childhood Obesity Research…

Mother-child storytelling is a universal activity that predicts literacy development and can play a promising role in developing strong parent-school connections among first-generation Latino families. By examining the discourse patterns of 34, 5-7 year old dyads on a fictional storytelling task, our results revealed that maternal elaborative and…

Spatial-Temporal Math (ST Math) is game-based, instructional software for K-12 students created by the MIND Research Institute (MIND). ST Math is integrated into classroom instruction, but can also be used in a computer lab or at home. The ST Math software games begin without language and symbol abstractions by posing math programs as purely…

Finding context, examples, and ample hands-on experimentation is fundamental for understanding complex ideas in subjects such as science and math. Recent popularity of competitive robotics has become a catalyst in the development of DIY and hobby kits. Manufacturers have made available easy to work, re-configurable, and functional, structural…

This integrative review examined correlates, mechanisms, and consequences of teacher bias experienced in pre-kindergarten through twelfth grade in primary and secondary schools in the United States.
