Professional development (PD) has been widely implemented to shift mathematics instruction practices from teacher-centered (traditional practice) to studentcentered. As such, a study examining mediating factors on the relationship between PD and student-centered instruction is of great importance in enhancing the effectiveness of PD and shifting…

Before school closures due to the COVID-19 pandemic, the frequency with which teachers used computer activities to teach a class varied across education systems. However, many teachers across the board reported the need for professional development to teach using technical devices. Using results from TIMSS (Trends in International Mathematics and…

With the proliferation of video-based professional development (PD) courses for mathematics teachers, understanding the role of the facilitators of these courses has become an emerging field of theoretical and empirical study. The purpose of this article is to address some of the challenges and opportunities that facilitation of discussions…

This is the second of 2 reports that look at the results of TIMSS 2023 and Australia's performance. This report, Volume II, presents the results from the contextual questionnaires, and examines the home, school, and classroom contexts in which learning and achievement occur, as well as student attitudes. Each chapter focuses on different…

In this study, secondary school mathematics teachers' the opinions related to skills-based questions that are compatible with the LGS (High School Transition Exam) question style were examined. Qualitative research methods were adopted in the study. Mathematics teachers working in secondary schools in various parts of Turkey participated in the…

The purpose of this study is to explore elementary educators' perceptions regarding what it means to conceptually understand mathematics, the emphasis teachers place on utilizing evidence-based teaching processes, as identified as effective by National Council of Teachers of Mathematics (NCTM), and how these perceptions influence their…

It is a common knowledge that student achievement is a product of multiple individual and environmental factors. The literature developed various models to organize and explain the relationship between some of these variables and student learning which translates into student achievement. Yet, no comprehensive model is able to capture all possible…

Purpose: To advance a framework of indicators that promotes implementation of math standards under the Every Student Succeeds Act (ESSA), we tested a conceptual model of the resources and processes within schools that influence the opportunity to learn mathematics (OTL) in the classroom using a recent administration of the 2011 Trends in…

Educators in forty-five states and the District of Columbia are hard at work interpreting and implementing the Common Core State Standards for Mathematics (CCSSM) (CCSSI 2010). This work typically involves teacher participation in professional development activities focused on developing an understanding of the content standards as well as the…

The Common Core State Standards (CCSS) were developed through an unprecedented, state-led initiative that drew on the expertise of teachers, parents, administrators, researchers and content experts from across the country. The Standards define a staircase to college and career readiness, building on the best of previous state standards in English…

This report analyzes teacher education and development policies in countries that participated in the Repeat of the Third International Mathematics and Science Study at the Eighth Grade and scored as well as or higher than the United States, also providing information on the systems of Australia, England, Hong Kong, Japan, Korea, the Netherlands,…
