2015 개정 교육과정에 기반한 영어Ⅱ 교과서에 나타난 파생 접사 연구

Based on the 2015 Revised National Curriculum, 9 High School English II textbooks were screened and published. These tex tbooks complied with the Vocabulary Guide of the English Curriculum which treats a headword and all its derivational forms as belonging to a single word. This work is first concerned with whether the distribution of derivative affixes is the same across these textbooks. It was shown that the frequency of Bauer and Nation’s (1993) 6-level-word-family derivative affixes is significantly different according to the textbooks. The work then tried to define representative derivative affixes for the textbooks. Examination of the coefficient of usage of derivative affixes suggested that the following 13 suffixes are representative: -ly, -al, -ion, -er, -ation, -ity, -ment, -ive, -ful, -ent, -y, -ant and -ist. These affixes are quite similar to the representative derivative affixes for the English Section of College Scholastic Ability Test but substantially different from the ones for elementary and middle school English textbooks. The work is concluded with some implications of its findings.
