Across many international contexts, more recent standards-based and other educational reforms have largely intended to transform teaching. Given the importance of teacher learning to such transformations, we argue that a learning-focused support approach will be essential if such reforms are to be productively taken up by schools and teachers. We…

The present study aims to compare the geometry standards in U.S. Common Core State Standards of Mathematics (CCSSM) and Chinese Compulsory Education Mathematics Curriculum Standards (CMCS) through the lens of van Hiele levels. The study considered a standard unit as one or multiple learning expectation(s) and placed each learning expectation into…

Improving children's "number sense" has been a core component of recent mathematics curricular and instructional reforms (CCSS, 2010; NCTM, 2000, 2014) in the United States. Students with mature number sense make sense of numbers and operations, use reasoning to notice patterns, and flexibly select the most effective and efficient…

The Common Core State Standards in Mathematics and Next Generation Science Standards encourage substantial shifts in teaching, but how to enact change is not specified. This mixed-methods exploratory study shows how different implementation supports were related to teachers' use of standards-aligned instructional practices in the Chicago Public…

The Common Core State Standards for Mathematics emphasize the importance of developing students' conceptual understanding, mathematical reasoning, and problem solving skills. This is a shift from the traditional approach to teaching mathematics and many teachers rely on curriculum resources to help them meet these new standards and expectations.…

The teaching profession requires continuous learning, and in 2014, a new model of professional learning was introduced in California by the Instructional Leadership Corps (ILC), a group of expert teachers who organize local professional development to spark iterative changes in practice. In the four years following its launch, the ILC connected…

The Common Core State Standards in Mathematics (CCSS-M) were released in 2010 with a goal to improve critical thinking skills and prepare all students to thrive in college, careers, and as informed citizens. The Next Generation Science Standards (NGSS) followed in 2013. Using districtwide surveys of students in grades 6-8, conducted annually from…

The year students take Algebra I historically determines how far they progress in secondary mathematics, creating complex equity issues around access to this course. By examining a case study of one large, urban school district adjusting to the Common Core State Standards in Mathematics (CCSS-M), we demonstrate how district leaders' interactions,…

The purpose of this study was to examine the process through which high school mathematics teachers direct their own learning and professional growth. Improving our understanding of the process of self-directed learning has significance in the field of mathematics education due to the degree to which the Common Core State Standards movement has…

In the United States, the prevailing high school mathematics course sequence begins with a year of Algebra I, followed by a year of geometry and a year of Algebra II. Educators and others have raised concerns about the extent to which this sequence, which prioritizes the mastery of algebra, is appropriate for the longer-term education and career…

School reform efforts are reflected in the Common Core State Standards (CCSS) and increasingly impact potential for differentiation of instruction, which is critical in effectively educating students with varying achievement and learning needs. Although CCSS were developed to establish a ubiquitous foundation of educational expectations by grade…

A decade ago, states across the nation adopted the Common Core State Standards (CCSS) in an effort to raise the academic bar for their students. This has provoked countless political battles since then--including an especially intense one in Florida. That fight culminated in Governor Ron DeSantis vowing to eliminate and replace the Common Core,…

Concerns with the teaching and learning of mathematics have been ongoing (Chard, Baker, Clarke, Jungjohann, Davis, & Smolkowski, 2008; Hill & Ball, 2004; Thames & Ball, 2013). An extensive review of the literature shows that many mathematics reforms have been implemented with the intention of improving the teaching and learning of…

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…

Open-ended questions that can be solved using different strategies help students learn and integrate content, and provide teachers with greater insights into students' unique capabilities and levels of understanding. This article provides a problem that was modified to allow for multiple approaches. Students tended to employ high-powered, complex,…
