Five years into the Common Core initiative, researchers and the general public are interested to know whether and how the standards are "working." In this introduction to the special topic, I discuss the state of the literature on these questions and offer suggestions for what I view as the most important work moving forward.

In their proposals to join the Math in Common (MiC) initiative, staff from each of the 10 participating districts acknowledged that the shifts required to implement the Common Core State Standards for Mathematics (CCSS-M) (NGA Center & CCSSO, 2010) would be a huge lift for teachers. They knew that mathematics teachers would be required to take…

Reading and writing translate to centuries of shared knowledge and can be expanded upon with the ability to acquire multiple tongues. In response to today's most widely spoken languages, Chinese/English and Spanish/English dual language immersion programs continue to grow across the United States. Unfortunately, the lack of uniformity in the…

Imagine a mathematics classroom in which students engage in sharing ideas and reasoning through solutions to interesting mathematical problems. They are excited about mathematics and working on challenging problems that encourage collaboration and critical thinking. These are things that teachers want, but sometimes they do not know how to achieve…

Statistics standards found in the Common Core (CCSSI 2010) and other state standards require considerable instructional time and focus for students to develop the depth and breadth of understanding necessary. In this article, the authors offer an approach to teaching a statistics unit that combines student choice with authentic and sustained…

Is the Common Core really "dead"? Though no longer called the Common Core in our three study states, the "new" college-and-career readiness standards still guide much of education policy in Texas, Ohio, and Kentucky. In our new feature article in "Educational Researcher," lead author Dr. Laura Desimone, along with…

The Common Core State Standards (CCSS) began to take form when dozens of educators from across the country were led by governors and chief state school officers in gathering and reviewing the academic standards of states that had the best outcomes. Their goal was to determine what the current best academic standards were in the country and then…

Many educators may view use of Open Educational Resources (OERs) as a new trend that has emerged in various school districts, especially those OERs that are (Common Core State Standards) CCSS-aligned. However, OERs certainly aren't new to education. Many educators have been using these types of materials since the late 1990s (Godwin 2016).…

For school districts in California, just as one set of revolutionary new content standards is beginning to feel familiar, another deep change is brewing. Districts have now had more than five years to wrestle with how they implement the Common Core State Standards for Mathematics (CCSS-M) (NGA Center & CCSSO, 2010). Many have made large-scale…

This brief summarizes lessons from "positive outlier" districts in California that have excelled at helping African American, Latino/a, and White students achieve at high levels on new assessments of academic standards in English language arts and mathematics, after accounting for students' socioeconomic status. Drawing on case studies…

This article reports on why states are quitting the Partnership for Assessment of Readiness for College and Careers (PARCC) and Smarter Balanced Assessment Consortium (SBAC). The two consortia sought to develop state-of-the-art assessments that focused on problem solving and the application of knowledge, and that moved away from former tests'…

Policy makers at the federal level have embraced an educator effectiveness agenda, which in turn has driven many states across the country to rapidly develop and implement new and more complex teacher evaluation systems. It is increasingly clear that the success of these nascent teacher evaluation systems partly depends on the will, skill and…

Teachers face many challenges helping students meet the expectations set forth in the Common Core State Standards for Mathematics (CCSSM) (CCSSI 2010). CCSSM content standards not only introduce new concepts at each grade level but also require teachers to learn new terminology for old concepts and consider how students' understanding of concepts…

Project-based learning (PBL) is an inquiry-based instructional approach that allows students to gain knowledge and skills by investigating and respond to engaging, complex problems or challenges. For some, PBL may seem like an unnatural fit in PE classrooms. However, this article describes how, with careful and creative planning, PBL can easily…

The Common Core State Standards (CCSS) for English language arts have been adopted by many states across the country in an effort to prepare students for life after high school, whether that be going to college or joining the work force. The anchor standards of the CCSS, known as the College and Career Ready Standards, describe the literacy skills…
