Study On The Issue Of Validity Of National College Entrance Examination

Validity is the core index of the scientific nature of evaluation test. This thesis takes the issue of validity of NCEE (National College Entrance Examination) as the target of study, based on the description of the validity of NCEE. Gets the validity coefficient of every major via the calculation to a great number of raw data using SPSS software. Analyze the result deeply via test theory, and discuss the basic issues on validity of NCEE, based on the analyses of the characteristics of validity of NCEE.On the basis of discrimination on NCEE,introduction on validity,difference between function and competence of NCEE, make clear the importance of study on the issue of validity of NCEE and the entrance point of the study. In the part of quantity study, firstly give the necessary introduction to the assumption and study the issue on the selection of criterion, then calculate the validity of NCEE using the criterion of total score, describe the general characteristics of validity of NCEE, and compare the different and similar validity of NCEE when taking different criterion such as total score,public course score and specialized course score. On the basis of general mastery to the characteristics of validity of NCEE, conduct the quantity study on the following issues: validity of different group, the relating condition between the score of every subject in NCEE and the schoolwork score in college, validity of English and Math in NCEE, minus relating issue on the scientific nature of enrolling index etc. Based on the quantity study, Conduct deeper study on the following basic issues: the explanation and improvement of validity of NCEE, the effective factors of validity of NCEE, the way to improve validity of NCEE, the practical condition for the improvement of validity of NCEE etc.The study makes the following conclusions: at the beginning period of the recovery of NCEE, Validity of NCEE for Study-based university was much better than other types of university in terms of selecting suitable students, with time passing, the difference between different types of university becomes narrower obviously, which reflects the changing characteristics of "elite" to "mass"; Based on practical background, NCEE could select suitable students for universities on the whole; After stepping into the period of mass higher education, the high enrolling ratio and balancing trend of selecting good students in NCEE makes the classifying-reform a necessary way to improve validity of NCEE. The application of test theory and technique as well as the benefit adjustment in relating group restricts the conduct of classifying-reform of NCEE.
