This report describes the authors' findings from a scoping literature review on the topic of instructional system coherence. The authors reviewed 77 pieces on coherence published from 1990 to 2023, including articles, reports, books, dissertations, and conference papers. The scope and definition of alignment and coherence have seemed to expand…

In 2023, California will implement a new statewide math framework that will drive curriculum decisions and pedagogical approaches for years to come. Although the state's content standards for mathematics are not changing, a statewide framework could nevertheless shift instruction by providing educators with guidance on how to implement content…

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…

Providing clear guidance to teachers is not a straightforward task for school systems: Teachers get information about what to teach and how to teach from many sources, some of which are beyond the control of school systems. When teachers get different, even conflicting, messages about what and how to teach from various sources, they likely…

This report uses Spring 2022 data from nationally representative surveys of principals and math teachers in kindergarten through grade 12 (K-12) to explore students' opportunities to prepare for and take advanced math. The authors found that small high schools, high schools in rural areas, and high schools that predominantly serve students from…

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…

Media literacy (ML) education has emerged as a promising approach to slowing the spread of "Truth Decay," described as the diminishing role that facts, data, and analysis play in political and civil discourse. Several factors contribute to Truth Decay, including a rapidly evolving information ecosystem and overburdened educational…

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. The authors conceive of…

Policymakers and practitioners alike have increasingly positioned instructional materials as essential for achieving high-quality, standards-aligned instruction. State education agencies, school districts, and schools have looked to instructional materials to signal what to teach and to what depth for students to be on track to meet college- and…

Much research has noted the misalignment between kindergarten through 12th grade (K-12) academic standards and curriculum materials used in classrooms. 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…

If a "curriculum" -- a set of instructional materials intended as a comprehensive course of study for a particular subject and grade level -- is well-aligned with state standards, it can help teachers deliver instruction that leads to students' mastery of those standards. However, most research suggests that curricula, in themselves, are…

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…

The authors of this report build on past studies by using survey data from a nationally representative sample to examine how middle and high school English language arts (ELA) and mathematics teachers use and perceive their instructional materials in terms of engagement, challenge, and usability. In addition, the authors use interview data to…

Just as teachers' perceptions of instructional materials influence what they do with those materials, school leaders' perceptions of instructional materials influence their decisions about how and how strongly to support teachers' material use. The authors address a gap in existing literature by identifying what school leaders regard as key…

This technical report provides information about the sample, survey instrument, and resultant data for the American Instructional Resources Surveys (AIRS) that were administered to principals and teachers in spring 2019 via RAND's American Educator Panels. The AIRS focused on instructional resources used and supported in English language arts,…
