School principals are critical to students' academic achievement, second only to teachers. They are the primary agents of change in their schools, fostering supportive learning environments that enhance student learning and teacher effectiveness. Moreover, they often design and oversee the initiatives and hiring to sustain the positive changes…

Standards-based reform is a key feature of U.S. education policy. Several decades ago, scholars posited that if states set ambitious standards and then aligned curriculum, assessments, and professional development (PD) to those standards, teaching and learning would improve. However, the focus on establishing standards has often overshadowed the…

Nationwide, a growing percentage of kindergarten through grade 12 (K-12) teachers report regularly using standards-aligned English language arts and math curriculum materials. Despite this uptick in the regular usage of standards-aligned materials across the United States, not all teachers use these materials for the majority of their…

Researchers draw on the American Instructional Resources Survey (AIRS) and interviews with 45 English language arts (ELA) and math teachers to examine the prevalence of different types of benchmark assessments and explore educators' perceptions about the extent to which benchmark assessments align with other components of their schools'…

Policymakers and practitioners increasingly have looked to instructional materials to signal the content that students are expected to learn and how to teach that content. The American Instructional Resources Survey (AIRS) has been investigating adoption and use of instructional materials in K-12 public schools in the spring of each school year…

Past research suggests that it is common for teachers to draw on multiple instructional materials even when their school or district recommends, requires, or provides them with a specific curriculum. While teachers likely draw on a variety of resources to address changing and diverse student needs, studies show that teacher-selected materials can…

RAND researchers explore the messages teachers receive about what to teach and how to teach English language arts and mathematics in kindergarten through grade 12 schools in the United States, as well as teachers' overall perceptions of coherence and incoherence in instructional systems and how they navigate such systems.

Many states and education organizations have been pushing for greater use of standards-aligned curriculum, especially during the past several years. In this report, the authors share results…

Students with disabilities often face barriers that hinder their capacity to access general education curricula and show their learning. Modifications to curricula and lesson plans can help reduce these barriers. Modifications are changes to what instruction is delivered--which tasks students complete and what content they learn. Previous research…

A large body of research demonstrates that teaching students explicitly about issues of identity, diversity, equity, and bias--sometimes referred to as "anti-bias" education--can lead to positive academic, attitudinal, and behavioral outcomes. Explicit instruction around issues of oppression, equity, and activism can support students'…

Ambitious federal goals for preparing students for careers in science, technology, engineering, and mathematics (STEM) fields require coordinated efforts and supports for the country's science instructors. Increased attention to the needs of science instructors and the provision of supports to address those needs are particularly important in…
