In 2010, California adopted the Common Core State Standards (CCSS) for math and English. The new standards are part of a state effort to prepare students for college and careers in the 21st-century global economy and narrow longstanding achievement gaps. The state's implementation is complete, but because districts decide whether and when they…

The Common Core State Standards for Mathematics have a widespread impact on children's statistical learning opportunities. The Grade 6 standards are particularly ambitious in the goals they set. In this critique, experiences helping children work toward the Grade 6 Common Core statistics expectations are used in conjunction with previous research…

This study uses survey data to assess the influences of Common Core State Standards on teacher self-efficacy. Participants in this study included African-American teachers (who taught at least one special education student) from an online network that hosts approximately 153,000 members from across the United States. A convenience sample of 156…

This study explored the knowledge elementary teachers need for one core practice: reading and responding to students' writing. Forty-five preservice teachers read and responded to an elementary student's narrative writing sample. Using teacher noticing as a framework, we first decomposed the practice into five components indicative of differences…

Being proficient in independently reading and writing complex informational text has become a need for college and career success. While there is a great deal of agreement on the importance of the reading of informational text in early grades and teachers are encouraged to increase amount of the reading of informational text in early grades, few…

The Programme of International Student Assessment (PISA) has been administered to 15-year- olds every three years since 2000. Since then, the U.S. has performed below average in mathematics, with no significant changes in performance. The objective of this study was to examine the alignment of the content students in the U.S. are assessed on in…

Five-plus years into the experiment with new "college- and career-ready standards" (of which Common Core is the most notable and most controversial example), we know little about teachers' implementation and the ways policy can support that implementation. This paper uses new state-representative teacher survey data to characterize the…

The authors recently conducted a randomized controlled trial that showed a significant impact of teachers' lesson study, supported by mathematical resources, on both teachers' and students' understanding of fractions. The research and mathematical resources are described in the second part of this article. First the authors examine some of the…

Nearly two dozen states now administer online exams. These tests have real consequences: their results feed into accountability systems, which have been used for more than a decade to hold schools and districts accountable for their students' learning. We examine the rollout of computer-based testing in Massachusetts over 2 years to investigate…

This study applied sociocultural theory to examine the theoretical beliefs teachers have concerning language and language acquisition and how these beliefs influenced their perceptions of the Common Core State Standards as a means of closing the achievement gap for English learners. This quantitative study analyzed teachers with differing…

Statistical association between two variables is one of the fundamental statistical ideas in school curricula. Reasoning about statistical association has been deemed one of the most important cognitive activities that humans perform. Students are typically introduced to statistical association through the study of the line of best fit because it…

With the adoption of the Common Core State Standards (CCSS) and in preparation for standards-aligned assessments and twenty-first-century literacy demands, the needs of the adolescents who struggle with reading demand attention. Students who exhibit poor literacy levels have historically occupied seats in secondary classrooms, but the likelihood…

The purpose of this study was to explore specific leadership practices of high school principals, as identified by teachers and principals, and these practices' relationship to student achievement in English language arts. The measurements used for student achievement in English language arts were the proficiency percentages on the 2016 New York…

The Language and Writing strands of the Common Core State Standards place a heavy emphasis on sentence-level conventions including syntax/grammar and mechanics. Interventions targeting these foundational skills are necessary to support struggling writers, as poorly developed sentence construction skills inhibit more complex writing tasks. This…

The Common Core State Standards (CCSS) were adopted in an effort to create a consistent set of standards across schools, districts, and states in order to ensure equality of educational opportunities for all students in the country. Educational reform through standardization implies that across thousands of miles and millions of students,…
