Accurate, reliable, and scalable measurement of classroom quality represent a critical tool for ensuring that young children benefit from early learning programs. The Early Childhood Classroom Observation (ECCO) study was designed to better understand how video recordings can support high-quality measurement of pre-kindergarten (pre-K) classrooms,…

To provide a landscape of mathematics activities children experience in U.S. preschool and kindergarten classrooms, we observed time children spent in mathematics activities (and -- as a contrast -- literacy) in 101 geographically diverse early childhood classrooms in seven U.S. states. We also observed what mathematics content, grouping…

The Optimizing Learning Opportunities for Students (OLOS) Observation System was developed by the Early Learning Network's assessment team at the University of California, Irvine. OLOS is a user-friendly, web-based tool designed to help teachers understand what is happening in their classrooms and uncover ways to meet the unique learning needs of…

Observation tools that measure the quality of children's classroom experiences are a key component of pre-K quality improvement initiatives. However, the information provided by these tools has limitations for improving the quality of instruction for the full range of pre-K program types, even when supported by an instructional coach. This report…

As a result of the COVID-19 pandemic, many instructors were forced to adjust from in-person to emergency remote teaching; however, classroom observation protocols, like the Classroom Observation Protocol for Undergraduate STEM (COPUS), have only been developed and validated for in-person instruction. Therefore, we developed and validated an…

Early childhood education programs (ECE) invest in assessments of classroom quality to enable accountability and to enact efforts towards quality improvement. The "Early Childhood Environment Rating System -- Revised" (ECERS-R) and "Classroom Assessment Scoring System" (CLASS) are two widely used classroom quality assessments…

The researchers piloted an observational protocol to examine the Universal Design for Learning (UDL) principles and checkpoint strategies used during daily instruction with a small sample of general and special education teachers. Observational research on UDL has been recommended within the literature. Researchers used the high-leverage practice…

The notion that teacher quality impacts student achievement is widely accepted. How to best define, measure, and improve teacher quality continues to be debated by teacher unions and state legislators. Teacher evaluation studies have focused on isolated elements of the system. The purpose of this quantitative study was to examine the current…

Classroom observations are an integral component of teacher evaluation systems, but little is known about who is best qualified to observe and evaluate special educators, who have a specialized skillset, and whether observation instruments adequately reflect their instructional practices. In this study, 19 special education teachers in California…

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 study assesses the reliability of two observation rubrics, one in math and the other in science, and documents how the rubric data were used to inform a teacher education program. Classroom observations are typically considered essential for assessing teaching practice, yet many popular observation frameworks, while comprehensive in aim, do…

Exploring parent, student, and teacher language moves is essential to develop and implement strategies that cultivate Spanish use in support of dual-language engagement. We used Lareau's concerted cultivation framework to explore language use at a K-8 dual-language immersion school. A case-study design integrating content analysis was used to…

The report contains real-world, proven school climate strategies to guide policymakers in building a comprehensive and coherent state-wide approach for improving school climate. It features 12 recommendations linked to existing state policy examples policymakers can use to build a comprehensive, coherent state-wide approach for improving school…

Introductory science, math, and engineering courses often have problems related to student engagement, achievement, and course completion. To begin examining these issues in greater depth, this pilot study compared student engagement, achievement, and course completion in a small and large section of an introductory biology class. Results based on…

Publicly funded pre-K is often touted as a means to narrow achievement gaps, but this goal is less likely to be achieved if poor and/or minority children do not, at a minimum, attend equal quality pre-K as their non-poor, non-minority peers. In this paper, I find large "quality gaps" in public pre-K between poor, minority students and…
