| Summary: | 碩士 === 國立政治大學 === 英語教學碩士在職專班 === 94 === The purpose of this study is to investigate the content validity of Basic Competence Test (BCT) in English, hoping to verify whether or not the test reaches what the tester claims to test, and further promote a better understanding of BCT toward teachers, students, educators and the public.
This study adopts both qualitative and quantitative analyses. Fifty-one qualified junior high school teachers examine the relationship between BCT’s items and curricular instruction from textbook coverage, instruction, evaluation, and item difficulty. They also offer their perceptions toward BCT from the content domain the tester claims to test, i.e. the general and specific objectives of Curriculum Standards, test principles from the BCT Center, and Core Competence Indicators. Aiken’s Validity Index checks if items are significantly content valid. Computing the correlation coefficient between 1204 students’ academic scores of monthly tests for three years at four schools and BCT’s raw scores does the quantitative analysis.
The result of this study indicates that first BCT items have high accordance with curricular instruction. Second, students’ performance at school correlates highly to that on BCT. Third, what the BCT Center claims to test is highly acclaimed by the junior high school teachers. In other words, BCT’s content validity is established.
