Recent genetic discoveries offer a new lens through which to study cognitive, emotional, behavioral, and social processes that are foundational to children's development. In this article, we review the latest advances in genomics--genome-wide association studies and the polygenic scores that have come out of them--and discuss how these techniques…

School dropout is a structural problem which permanently penalizes students and society in areas such as low qualification jobs, higher poverty levels and lower life expectancy, lower pensions, and higher economic burden for governments. Given these high consequences and the surge of the problem due to COVID-19 pandemic, in this paper we propose a…

Learning progressions have become an important construct in educational research, in part because of their ability to inform the design of coherent standards, curricula, assessments, and instruction. In this paper, I discuss how a learning progressions approach has guided our development of an early algebra innovation for the elementary grades and…

The development and use of learning trajectories is a body of research that has made enormous contributions to the field of mathematics education, offering insight into the teaching and learning of topics at all levels. Simultaneously, the work of building learning trajectories can benefit from explicitly adopting an anti-deficit stance,…

This is the executive summary for the full report, "Classroom-Based STEM Assessment: Contemporary Issues and Perspectives." This report is focused on what research and practice indicate about how assessment impacts the teaching and learning of STEM subject matter in K-12 classrooms. The intent is to take stock of what is currently known…

Major developments over the past two decades in STEM education and classroom assessment provide a compelling argument for shifting the focus of assessment toward the classroom where its most powerful benefits can be realized. The increased emphasis on diversity, equity, and inclusion in education puts increased scrutiny on assessment practices and…

This brief provides findings from the full report, "Adapting to Changes in California's English Learner Population," which examines how the size and composition of the English Learner (EL) population has changed and whether services, program offerings, and learning trajectories have evolved in response to these changes. Key findings…

California's K-12 funding and instructional policies for English learners (ELs) have changed significantly over the past 2 decades, including new requirements for instructional materials specific to ELs statewide and a new school funding system that funds ELs at a higher rate. These major policy shifts held the potential to change student learning…

We describe here lessons learned in designing an early algebra curriculum to measure early algebra's impact on children's algebra readiness for middle grades. The curriculum was developed to supplement regular mathematics instruction in Grades K-5. Lessons learned centered around the importance of several key factors, including using conceptual…

In February 2020, the Ministry of Education asked the New Zealand Council for Educational Research (NZCER) to examine the curriculum-levelling construct that sits at the heart of The New Zealand Curriculum (Ministry of Education, 2007). A key goal of the research was to investigate, whether-- and if so, how--the construct helps (or hinders)…
