参考答案：错

解析：[听力原文]Smaller class sizes in early grades translated into students scoring higher on math tests in later grades in Tennessee’s experiment to see if smaller classes improved education, a study said of Friday.

[分析]： 语义的理解和判断。 根据原文，该实验的目的是... to see if smaller classes improved education 即看小班教学是否提高教育质量，而结果证明确实有效。因此题干的说法与原文不符，是错误的。[解题关键] 掌握动词不定式表目的的用法，这里原文中to see表目的。
