The OECD's global testing products (Programme for International Student Assessment [PISA] and Trends in International and Mathematics and Science Study [TIMMS}) are creating global standards for the knowledge students need in order to complete in a global market. Nations also use these tests to compare the scores of their students with those in other countries. Review the "Highlights From TIMSS and TIMSS Advanced 2015" article and discuss the performance of U.S. students as compared to their counterparts in other countries. How are American students performing compared to their counterparts? Given that countries use these scores as benchmarks, what recommendations for curricular reform in math do these scores indicate?
