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…

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…

Live video web-streaming via an electronic field trip (EFT) format can connect youth with scientists working in a variety of settings. Previous research indicated interactions with scientists can change children's perceptions of science, technology, engineering, and mathematic (STEM) careers. We conducted an arts-based study to examine an EFT's…

Construct confusion and measurement challenges have plagued emergent literacy research for decades. Using a 2 × 2 × 2 factorial design, this study evaluated the dimensionality of alphabet knowledge and identified the sequence of development of 8 alphabet knowledge skills. Eleven models were evaluated in a sample of 3,692 preschool- and elementary…

As many U.S. school administrators create policies around hair, many often neglect to consider racial differences, especially those pertaining to hair care and maintenance styles. News media outlets have recently highlighted the ways schools create and sustain racially biased policies and schooling environments, demonstrating the media's role in…

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…

In 2019, the National Center for Education Statistics (NCES) began exploratory data collection for the School Pension Survey (SPS). The SPS is a new data collection of elementary/secondary school teacher pension data collected at the school district level. The SPS was developed primarily in response to public demand for data on teacher and other…

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. Education Resource and Information Center, Sociological Abstracts, and Applied Social Science Index & Abstracts were searched to identify…

Researchers explored how 13 states in which policymakers have adopted an A-F school letter grade accountability system performed on the National Assessment of Educational Progress (NAEP) post-policy implementation. Researchers found mixed results, with approximately half of these 13 states increasing achievement post-policy, and the other…

Educators in PK-12 schools were surveyed to seek their perceptions of colleagues who they considered informal teacher leaders, defined as leaders who were not appointed to a leadership role by a school or district administrator. The survey asked administrators, educational specialists, and teachers working in PK-12 schools across four states to…

"Saxon Math," published by Houghton Mifflin Harcourt, is a core curriculum for students in grades K-5. A distinguishing feature of the curriculum is its use of an incremental approach for instruction and assessment. This approach limits the amount of new math content delivered to students each day and allows time for daily practice. New…

If there ever was a time for educators to understand the experiences of Latino students, that time is now. Increases in anti-immigration expressions and sentiments and the very real rollback of federal protections have created an unsafe and unsettling environment in this nation and in its schools. One of the greatest resources to help educators…
