In 2010, California adopted the Common Core State Standards (CCSS) for math and English. The new standards are part of a state effort to prepare students for college and careers in the 21st-century global economy and narrow longstanding achievement gaps. The state's implementation is complete, but because districts decide whether and when they…

This qualitative multiple case study examined the beliefs and behaviors of three teachers who worked at former Reading First Schools and whose student population consistently scored 10% above state average on the California Standards Test (CST) in English language arts. Test scores of all teachers who taught under the Reading First initiative at…

The purpose of this evaluation was to examine the impact of i-Ready Personalized Instruction on reading achievement, as measured by SBA scores. We compared students in schools using i-Ready Personalized Instruction school-wide (Treatment students) to students who only received i-Ready Diagnostic assessments and who were in schools only partially…

In 2013, California became one of the first states to adopt the rigorous Next Generation Science Standards (NGSS). However, the current state of science instruction does not support the conceptual shifts of the NGSS, which call for consistent science instruction K-12, increased inquiry, subject integration, as well as science instruction that…

Teachers' beliefs, professional development, access to hardware/software, and instructional contexts all influence teachers' use of technology (Ertmer et al., 2012; González-Carriedo & Esprívalo Harrell, 2018; Ottenbreit-Leftwich et al., 2010). The first three factors have been studied extensively, but additional research on the instructional…

Measures of school-level growth in student outcomes are common tools for assessing the impacts of schools. The vast majority of these measures use standardized tests as the outcome of interest, even though emerging evidence demonstrates the importance of social-emotional learning (SEL). In this article, we present results from using the first…

Launched in 2012, The Big Lift is a collective impact initiative extending from preschool to third grade that aims to boost children's reading proficiency in San Mateo County, California, through four different types of activities, called "pillars": (1) High-Quality Preschool, (2) Summer Learning, (3) School Attendance, and (4) Family…

This study examines the associations between county-level immigration arrests and academic achievement, absenteeism, and measures of school climate and safety for students in the California CORE districts. We found consistent evidence that Latinx and Latinx English learner students experienced declines in academic achievement, attendance, and…

Classrooms nationwide welcome a diverse group of learners. A goal, and an achievable one, is to recognize this unique diversity on a whole child spectrum and to strive to customize learning to meet individual needs. Critical to this process is for teachers to have at hand research that connects factors of learning in a holistic way. It is equally…

A vast majority of elementary students struggle with the core, pre-algebraic concept of mathematical equivalence. The Improving Children's Understanding of Equivalence (ICUE) intervention integrates four research-based strategies to improve outcomes for second grade students: (1) introducing the equal sign before arithmetic, (2) non-traditional…

This study examined how heritage language and cultural funds of knowledge of Spanish-dominant Latinx immigrant families served as powerful resources for their concientización--critical awareness of important problems and social conditions--and bridged their cultural worlds of home, community, and school policy. The study drew on three…

Science achievement gaps exhibit racial disparities starting in primary grades and attitudes toward science have been shown to affect academic achievement and motivation. Leveraging the immersive nature of Virtual Reality 360 videos, we present a Design-based Research iteration testing how a novel technological-learning experience influenced our…

The purpose of this case study was to examine how one high-performing California TK-6th grade public elementary school had committed to the development of 21st century skills. Specifically, this study sought to identify the practices and structures at Utopia Elementary that allowed students of low socio-economic status and students with an…

California's K-12 funding and instructional policies for English learners (ELs) have changed significantly over the past 2 decades. The major policy shifts held the potential to change student learning outcome patterns for ELs. As a first step in identifying the potential impacts of these policy shifts, this report describes changes over time in…

A physical education lesson usually consists of four parts (introductory activity, fitness component, lesson focus, and closing game). The first part of the lesson, the introductory/warm-up activities, has the potential to set the tone for the rest of the lesson. It also provides an opportunity for students to get into instant activity upon…
