Impacts of TIMSS and PISA on Mathematics Curriculum Reforms

International assessment studies generally contribute to curriculum reform by highlighting certain aspects of curriculum needing improvement, usually attained though the recognition and application of some studies’ components. By focusing on the question “How have international studies driven school mathematics curriculum reforms?”, this chapter examines the role of international studies TIMSS (Trends in International Mathematics and Science Study) and PISA (Programme for International Student Assessment) in reforms in different countries. Emphasis is placed on examining components applied in (re)designing and implementing curriculum improvements. After presenting the global influences of TIMSS and PISA worldwide, the influences of these international studies are examined in case studies from four economically and geographically diverse countries. The chapter ends with a critical summary of the findings presented and outlines directions for further research
