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…

Although public K-12 student enrollment dropped by 3% nationwide in 2020-21, the school year that marks the onset of the COVID-19 pandemic, the patterns differ for specific areas and types of schools. This paper describes the COVID-19 and Equity in Education (CEE) Enrollment Explorer tool, which was developed to help policymakers and educators…

In this article, we demonstrate how playful learning serves to provide optimal learning opportunities through teacher-guided play. First, we describe the theoretical design principles that can be leveraged to support mathematical learning for students that have been underserved. Then, we provide concrete examples of evidence-based games that can…

The issue of unfinished learning and achievement gaps in schools has been a persistent concern in recent years, particularly among underrepresented and disadvantaged student populations.

The NGSS Early Implementers Initiative was created to help eight California school districts and two charter management organizations, supported by WestEd's K-12 Alliance, implement the Next Generation Science Standards (NGSS). Many educational initiatives are funded for only a couple of years. This unique initiative spanned an extraordinary six…

Over the course of six years, a diverse group of school districts and charter management organizations in California ran a substantial experiment in implementing the Next Generation Science Standards (NGSS) in elementary and middle grades. WestEd led an extensive evaluation of that effort, the California K-8 NGSS Early Implementers Initiative,…

This 13th report in WestEd's evaluation of the K-8 Early Implementers Initiative for the Next Generation Science Standards (NGSS) provides an extensive response to the following question: What does NGSS science teaching look like in the classroom? The report first discusses Initiative teachers' experiences with four instructional practices that…
