Low-income students and students of color are faced with pervasively lower levels of opportunity to learn compared with their peers, creating unequal opportunities for educational success. Textbooks, which serve as the backbone of the curriculum in most mathematics classrooms, present a potentially powerful tool to help mitigate unequal…

Researchers use data from the RAND American Mathematics Educator Study surveys of public school principals and teachers to investigate three school structures--referred to as "school opportunity structures" throughout this report--that may affect kindergarten through 8th grade (K-8) students' mathematics learning. These structures are…

Although there is substantial research that has guided middle school reform, there is insufficient support of Latinx students during their normative secondary transition (middle school to high school). Current research emphasizes that students who are not prepared when entering high school will face grim academic futures. The study explores the…

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…

Between 2003 and 2013, the proportion of California eighth graders enrolled in algebra or a more advanced course nearly doubled to 65%. In this article, we consider the organizational processes that accompanied this curricular intensification. Facing a complex set of accountability, institutional, technical/functional, and internal political…

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 the release of the Next Generation Science Standards (NGSS) in 2013. The new standards set off a chain reaction of standards adoption and…

Schools use an array of strategies to match curricula and instruction to students' heterogeneous skills. Although generations of scholars have debated ''tracking'' and its consequences, the literature fails to account for diversity of school-level sorting practices. In this article, we draw on the work of Sørensen and others to articulate and…

While the potential benefits of participating in online learning communities are documented, so too are inequities in terms of how different populations access and use them. We present the online learning support roles (OLSR) framework, an approach using both automated analytics and qualitative interpretation to identify and explore online…

Between 2003 and 2013, the proportion of California 8th graders enrolled in Algebra or a more advanced course nearly doubled to 65 percent. In this paper, we consider the organizational processes that accompanied this curricular intensification. Facing a complex set of accountability, institutional, technical/functional, and internal political…

These appendices accompany 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 the…

The purpose of this qualitative case study was to investigate the impact a robotics curriculum might have on the experiences and perceptions of middle school girls in two California classrooms. The research found that middle school girls in two different California classrooms felt that their experiences with robotics were personalized experiences…

In 2005, the Clarence Edwards middle school in Boston was failing. It was one of the lowest-performing schools in the city and on the verge of closure. Today, the school is thriving as one of Boston's highest-performing middle schools. The catalyst for this dramatic turnaround was the implementation of a new, partner-dependent expanded learning…

This five-year evaluation examined the effectiveness of a promising middle-school mathematics intervention funded through an Investing in Innovation (i3) development grant. Evaluation objectives were to: (1) study the impact of an intervention aimed at increasing the academic achievement of students in Algebra I--a gate-keeping course--as measured…

Engaging classes in every subject. Enriching encounters with the arts. Fun physical activities and healthy nutrition. Guided explorations of possible careers. Every young person deserves all of these experiences. At the moment, unfortunately, not all of the nation's children and youth do. This guide is intended to accompany the video…

The No Child Left Behind Act of 2001 has put many schools under a lot of pressure to meet its high demands. In this quantitative study, the effects that the NCLB act has had on students' opportunity to learn (OTL) and Subject Level Success (SS) from 2004 to 2012 in 9th, 10th, and 11th grade math coursework (Algebra 1, Geometry, Algebra 2, and…
