Given the importance of mathematics performance of learners and the challenges in South Africa, it is important that the expertise of all role-players, including the subject advisors who visit the teachers to guide and support them, is used to its full potential. While some studies have explored the experiences of teachers in this regard,…

This document lays out a curriculum framework for PK-grade 12 educational programs that is designed to help students achieve data literacy and become statistically literate. The framework and subsequent sections in this book recommend curriculum and implementation strategies covering PK-grade 12 statistics education.

Teachers' perceptions of written curriculum influence the way in which they use the curriculum. As multiple states begin to implement state specific standards, understanding the perceptions teachers may have of these standards is critical. This study used quantitative and qualitative methods to investigate the perceptions teachers had of one…

This technical report provides detailed information about the sample, survey instruments, and resultant data for the 2022 American Instructional Resources Surveys (AIRS) that were administered to principals and teachers in spring 2022 via the RAND Corporation's American Educator Panels (AEP). The 2022 AIRS focused on the usage of, perceptions of,…

Lesson study is a professional development activity that increases teachers' attention to student thinking. However, coordinating teachers' live observations of a lesson can be challenging. Using the framework of "distributed cognition," we investigate whether technology supports teachers' examination of student thinking and aids the…

The objective of this study is to better understand the process by which K-12 school districts select curricula materials in four critical subject areas: Mathematics, English Language Arts, Science, and History and Social Studies. This research has two primary goals: (1) to understand the process by which K-12 school districts select and adopt…

The Common Core State Standards in Mathematics (CCSSM) represent a major attempt in a long line of attempts to reform the American Education system surrounding Mathematics. These standards aim to establish a nationwide set of curriculum, seeking to ensure equity for all students in the U.S.A. Some of the standards included are new to all teachers…

Implementing educational innovations is far more complex than the straightforward execution of policy prescriptions. The diversity in implementation variants reflects an inherent tension between stabilizing and change-driven processes in school organizations. This article tries to capture this complexity by focusing on how individual and…

Lesson Study is rapidly becoming one of the most adopted models of teacher professional development worldwide. In this paper, we examine the teachers' discussions that are an integral part of the Lesson Study research cycle. In particular, we investigate the "dialogic mechanisms" that enable teachers' pedagogical intentions to be…

Shifting your high school's math program to new Common Core standards is much easier when teachers and leaders have this handy guide. Getting a copy for every staff member involved in the process ensures everyone knows: (1) How the six conceptual categories throughout the math standards are connected and reinforced; (2) How the modeling standards…

Adoption of the Common Core State Standards present challenges to school districts, school administrators, and teachers. To assist in this endeavor, we present our work on unpacking the CCSS-M for the length, area, and volume Learning Trajectory (LT). The overarching theme of "genetic epistemology" and a five-characteristic framework…

This article presents the extended workshop, a national professional development programme that was used in the preparatory stages of the introduction of a new mathematics curriculum for basic education (grades 1-9) in Portugal. These workshops are based on five major ideas-orientation towards practice, focus on students' learning, collaboration,…

This study focused on the use of curriculum materials for three teachers who had enacted instructional sequences from the materials on multiple occasions. The study investigated how the teachers drew on the materials, what they understood about the curriculum resources, and how they connected their use of the materials to their observations of…

This article presents a description of a South African mathematics teacher's struggles to mediate a new national assessment tool called the Common Tasks for Assessment with her grade 9 learners, who are unprepared for the assessment. The purpose of the study is to describe and to identify the constraints on the teacher's mediation attempts. The…

This paper investigates the contribution of mathematical knowledge for teaching (MKT) and curriculum materials to the mathematical quality of instruction by comparing the enactment of a fractions problem taught by two teachers with differing MKT. It was found that MKT seem to support teachers' precise use of mathematical language and to prevent…
