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…

Considerable research has documented the impact of teacher perceptions on students' academic-related outcomes (e.g., classroom performance). This body of literature clearly shows that teacher perceptions (resulting from direct interactions with students) can have both positive and negative effects with respect to student behaviors and experiences…

This action research study aimed to determine the effects of culturally relevant art integrated math lessons on African American students' engagement. The study took place in a fourth grade classroom at an urban elementary school in Northern California. In response to the study's research question: What impact does culturally relevant…

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…

Existing research on self-management skills shows that measures of self-management predict student success. However, these conclusions are based on small samples or narrowly defined self-management measures. Using a rich longitudinal dataset of 221,840 fourth through seventh grade students, this paper describes self-management gaps across student…

Focused on an equity of educational access issue, this qualitative study identified grade 4-6 teacher perceptions of English language learning in Southern California. The historic failure of English language learners (ELLs) on standardized tests in Southern California was presented as an important problem to solve. The literature review for this…

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,…

Bullying prevention efforts have yielded mixed effects over the last 20 years. Program effectiveness is driven by a number of factors (e.g., program elements and implementation), but there remains a dearth of understanding regarding the role of school climate on the impact of bullying prevention programs. This gap is surprising, given research…

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program to improve elementary students' vocabulary skills and reading comprehension. The study used a multi-site cluster randomized, experimental design, which randomly assigned 92 4th grade classrooms (n=2558 students) from two cohorts to a treatment or control…

The two studies reported on in this paper examine the features of words that distinguish students' performances on vocabulary assessments as a means of understanding what contributes to the ease or difficulty of vocabulary knowledge. The two studies differ in the type of assessment, the types of words that were studied, and the grade levels and…

We investigated what a cognitive framework for measuring classroom teaching could reveal about (a) the impact of a professional development (PD) program on teaching practices and (b) the relationship between teaching practices and student science learning. To conduct this study, we leveraged a collaboration between two entirely independent…

This research summary accompanies the report "Final Report of the i3 Impact Study of Making Sense of SCIENCE, 2016-17 through 2017-18." Science education has experienced a significant transition over the last decade, catalyzed by a re-envisioning of what students should know and be able to do in science. That re-envisioning culminated in…

Inquiry science instruction is especially challenging in elementary grades where teachers are constrained by crowded curricula and time. Professional development (PD) may provide an opportunity to support elementary teacher development of inquiry science instruction. The study examines the inquiry practice of two teachers who participated in an…

The purpose of this qualitative case study was to gain a better understanding of how induction programs might effectively support STEM K-8 teacher preparation. American schools are not producing competent STEM graduates prepared to meet employment demands. Over the next decade, STEM employment opportunities are expected to increase twice as fast…

A 12-week, 32-lesson afterschool intervention was conducted with third-to fifth-grade urban African American boys classified as aggressive. Grounded in attribution theory and organized around the construct of perceived responsibility in self and others, the intervention focused on increasing both social skills and academic motivation. Participants…
