TOEFL iBT模式的价值及对我国大规模外语水平测试的可参照性

TOEFL iBT的构念效度高于旧TOEFL，原因有三方面：测试内容更全面；改变了分立地测试语言能力的方法；测试了考生是否具有根据不同情景使用合适的语言的能力。TOEFL iBT测试模式的价值主要体现在其较高的构念效度。评分者间信度是我国大规模外语水平测试参照TOEFL iBT模式的障碍。我国的CET4和CET6应尽量参照TOEFL iBT模式，但主观题所占分值比例宜控制在30％左右。

Value of Testing Mode of TOEFL iBT and Its Imitability for Large -Scale Foreign Language Proficiency Tests in China

The construct validity of TOEFL iBT is higher than that of the old TOEFL due to 3 reasons： It has more complete test contents; It has changed the previous disintegrated testing methods; It uses communicative testing techniques. The value of the testing mode of TOEFL iBT is mainly reflected in its higher construct validity. Inter - rater reliability is the barrier for large - scale foreign language tests in China to imitate the testing mode of TOEFL iBT. CET-4 and CET- 6 should adopt the TOEFL iBT mode as much as possible, but the percentage of subjectively - rated test questions should be controlled at about 30%.
