절대평가 도입 전⦁후 수학능력시험 영어 읽기 지문의 어휘 분석 비교

초록

The purpose of the study was to investigate the differences in lexical analysis between CSAT English passages with an absolute grading system and a relative grading system. The analysis was performed by comparing the number of tokens, the number of types, vocabulary diversity(TTR), high-frequency words distribution, and readability in reading passages. The data were collected from CSAT English reading passages before introducing an absolute grading system in 2015, 2016, 2017, and then presented in 2018, 2019, and 2020. Two programs, AntConc3.5.8 and AntWordProfiler, were used to analyze the data files, and t-tests were used to determine significant differences between the two groups. The results showed that the number of word tokens, word types, and TTR were not significantly different between the two groups, confirming that the lexical composition of CSAT English reading passages remained the same. The high-frequency word distribution analyses showed significant differences between the two groups in a percentage of the 1st 1,000 high-frequency words, the academic words, and out-level words. It meant that the lexical level of reading passages in the absolute grading evaluation was more manageable than before introducing it. The readability score, FGKL, was not different between the two groups, but FRE was more difficult in the tests with an absolute grading system.
