TIMSS Geometry
Third International Math
& Science Study
57% of Swiss boys and
50% of Swiss girls correctly answered the TIMSS Geometry questions. But after
correcting for guesses on multiple choice questions and the error of 3%, only 18% of
American boys and 12% of American girls correctly answered these same question.
