This study analyses the communicative functions of listening scripts extracted from the 2015 elementary school English 6 and middle school English 1 textbooks in terms of continuity. Auditory data corpora were drawn from all five elementary school English textbooks and five most widely used middle school English textbooks. Each sentence of listening scripts was manually tagged based on the classification of communication functions presented in the 2015 Revised National Curriculum. The corpora were analyzed using 14 syntactic complexity measures with the L2 Syntactic Complexity Analyzer (Lu, 2010). The findings of this study show that the continuity between the elementary school English 6 and the middle school English 1 textbooks is relatively well-organized. However, concerning the sequence, the elementary school English 6 was found to be more complex than the middle school English 1 in terms of syntactic complexity. It is suggested that future textbook development should correct the reversed complexity in listening scripts found in this study.

The present study sought to examine the continuity of the English textbooks of the elementary school 6th grade and the middle school 1st grade by analyzing the readability and vocabulary difficulty of their reading passages. It investigated the continuity between textbooks of the two grades and among chapters of each textbook. For the analysis, Flesch-Kincaid Grade Level Index was used to measure the readability of reading passages, whereas vocabulary difficulty was measured in terms of TTR (type-token ratio) and frequency by using VocabProfile. The results showed that the readability of middle school textbooks was one point higher than that of elementary school textbooks. Given that the readability index is based on the American school system, the increase in readability index between grades can be seen as large gap. In terms of vocabulary difficulty, the total amount of vocabulary in the middle school textbooks was three times as much as that of the elementary school textbooks. Second, readability index fluctuated across the chapters of each textbook, while the TTR was found to be higher in the former chapters than in the latter chapters in elementary school textbooks. All these could lead to learning difficulties for students. Pedagogical implications are discussed.

This study aimed to identify the continuity between 6th grade elementary school English textbooks and 1st grade middle school English textbooks using Coh-Meu'ix, an automated web-based program designed to analyze and calculate the coherence oftexts on a wide range of measures. The measured value of text types was compared and classified into the surface linguistic features (the basic count, word rrequency, readabi li ty, connective information, pronoun information, word information) and the deep linguistic features (co-referential cohesion and semantic cohesion, lexical diversity, syntactic complexity). The findings were as follows: First, the basic counts and words before the main verb had a significant different value between two levels of textbooks. The results were remarkably different in the written language. Second, FKGL (Flesch-Kincaid Grade Level) and the pronoun ratio were significantly different only in the written language. In addition, type-token ratios in written language showed more significant differences than spoken language. Third, other language features showed only a mild and gradual difference. Finally, the resu lt indicated there were no statistical differences of discourse aspects.

목적: 제 7차 과학 교육과정과 국내 총 48종의 모든 초·중·고등 과학 교과서의 시각관련 개념을 안경광학적인 관점에서 분석하고자 하였다. 방법: 분석 방법은 질적 연구의 문헌 분석 방법을 사용하였다. 결과: 7학년의 `빛`단원과 8학년의 `자극과 반응`단원에서 오목렌즈와 볼록렌즈에 의한 시력교정 내용이 중복 설명되었다. 또한 7학년 `빛`단원에서 교육과정상에서는 문제가 없었으나 실제로 교과서에서 안경렌즈를 이용한 시력 교정원리가 다루어지는 것은 개념적 비약이었다. 8학년, 10학년 및 11학년 생물Ⅰ 단원의 홍채의 명암조절과 모양체의 원근조절 기전이 너무 단순화 되어서 정확히 이해하기 어렵게 서술되었다. 5학년의 `거울과 렌즈`단원에서 빛의 퍼짐과 모임만을 관찰한 후 7학년에서 시력교정 원리를 설명하는 것은 개념 수준의 적정성을 유지하지 못했고, 7학년과 8학년의 굴절이상 및 시력교정 원리에 대한 분석도 굴절이상의 원인에 일관성이 없었고 개념 수준이 역전된 교과서도 발견되었다. 5학년의 교과서에 설명한 초점거리에 대한 표현과 7학년 8학년의 망막 상 형성 과정에서 상의 표현이 모호하게 표현되었다. 또한 상이 맺히는 과정의 설명은 너무 지나치게 단순화 되어서 마치 바늘구멍 사진기와 같았다. 7학년, 8학년, 10학년, 11학년 물리Ⅰ, 생물Ⅰ 교과서에서 근시와 원시의 원인과 안경렌즈를 이용한 시력교정원리는 일관성이 없었다. 눈의 명암조절과 원근조절 작용은 지나치게 단순화 되어 서술되었다. 각막의 굴절력을 무시하고 빛이 지나가는 경로로써 투명한 각막의 역할만을 설명하고 있었다. 결론: 과학 교과서의 안경광학 관련 개념은 물리단원과 생물단원이 연계적 구성이 매우 중요하기 때문에 교과서 개발과정에서부터 충분한 협의와 검토를 통해 학습개념 수준의 적절성과 연계성을 유지하는 것이 매우 필요하다고 사료된다.
