The present study tests two predictions stemming from the hypothesis that a source of difficulty with rational numbers is interference from whole number magnitude knowledge. First, inhibitory control should be an independent predictor of fraction understanding, even after controlling for working memory. Second, if the source of interference is…

Educators often wonder exactly how the textbooks that end up in students' hands were approved. In this article, the author explores one significant stage in the process in California, the nation's largest textbook market. The Instructional Quality Commission (IQC), an advisory board to the California Department of Education's (CDE) State Board of…

The purpose of this study is to document how K-8 critically conscious, dual language, science teachers (CCDLSTs) working with bilingual learners (BLs) practice their critical consciousness via the four tenets of dual language education: ideological clarity, pedagogical perspective and clarity, access for all, and equitable spaces (IPAE). This…

NGSS Early Implementers is a four-year initiative created to help eight California school districts and two charter management organizations, supported by WestEd's K-12 Alliance, implement Next Generation Science Standards. The Initiative focuses on NGSS implementation in grades K-8 and incorporates the integrated course model (preferred by the…

The COVID-19 pandemic has had a huge impact on education. Science teaching, in particular, has faced specific challenges given the field's emphasis on high-quality instruction that has students "do" science collaboratively rather than just read about it or hear about it in a lecture. This brief provides: (1) a summary of data collected…

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…

Purpose/Objectives: In 2009, the Smarter Lunchroom Movement (SLM) strategy was created to provide schools across the United States (US) with evidence-based solutions to encourage healthier eating among children. Results, though, are inconsistent with how well this movement impacts school-aged children's healthy food selection and consumption.…

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…

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…

This study describes a strengths-based blended personalized learning model, the implementation of the model over a 4-year period, and the results of an impact study focused on measuring its effectiveness. The model includes many commonly-used features of personalized learning, including (a) competency-based progressions, (b) flexible learning…

NGSS Early Implementers is a six-year initiative 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). Administrators need learning opportunities if they are to adequately understand the substantial shifts of the Next…

These proceedings contain the papers of the 13th International Conference on Cognition and Exploratory Learning in the Digital Age (CELDA 2016), October 28-30, 2016, which has been organized by the International Association for Development of the Information Society (IADIS), co-organized by the University of Mannheim, Germany, and endorsed by the…

Ensuring that students have a strong foundation in mathematics by the end of 7th grade is essential if they are to move successfully into an advanced math curriculum that begins with algebra. But student achievement at the end of 7th grade varies widely in California--and this has consequences. Some 7th graders are taking a full Algebra I course;…

This report highlights the ongoing discussions between the believers of "online learning" vs. the "not enough proven research" for K-8 cyber schooling. Discussing successful processes and operations in states around the country, the author focuses on Maryland and, in particular, Baltimore schools, and reports that very little…
