    What is TIMSS?

    TIMSS (Trends in International Mathematics and Science Study) is designed to measure trends in students’ mathematics and science achievement in four-year cycles.

    Who conducts these studies?

    These studies are conducted by the International Association for Evaluation of Educational Achievement (IEA). IEA is an independent, international cooperative of national research institutions and governmental research agencies. They are based in Boston, Mass.

    How many TIMSS have been conducted so far?

    Conducted on a four-year cycle, the first round of TIMSS was in 1995, the second in 1999, the third in 2003, the fourth in 2007, and the fifth in 2011.

    AIR Study

    What is AIR?

    The American Institutes for Research (AIR) is one of the largest behavioral and social science research organizations in the world.

    What is the purpose of this study?

    Funded by the U.S. Department of Education, the study What the United States Can Learn From Singapore’s World-Class Mathematics System (and what Singapore can learn from the United States) identified major differences between the mathematics frameworks, textbooks, assessments, and teacher preparation in the U.S. and Singapore.

    What else does the study include?

    The study also includes initial results from four pilot programs that used the Singapore Math ® curriculum in place of their previous curriculum. The pilot programs involved students in Baltimore, Md., Montgomery County, Md., North Middlesex, Mass., and Paterson, N.J.

    What Singapore Math® books did these pilot programs use?

    All four pilot programs used the Primary Mathematics series.
