본 연구는 자동화된 통사 구문 분석 프로그램인 TAASSC를 활용하여 한국 대학생의 에세이에 나타난 영어능력 수준과 통사적 복잡성간의 관계를 살펴본다. 본 연구에서는 ICNALE 코퍼스에 포함된 한국인 대학생이 작성한 에세이를 분석하였고, 구 복잡성 지표와 절 복잡성 지표가 영어 수준을 얼마나 잘 예측할 수 있는지를 살펴보았다. 단계적 회귀분석 결과 구 복잡성 지표는 영어 능력 수준 변인의 8%, 절 복잡성 지표는 약 11%를 설명하는 것으로 나타났다. 따라서 절 복잡성 지표가 구 복잡성 지표보다 한국인 대학생의 영어 수준을 조금 더 잘 예측한다고 볼 수 있으며, 이는 구 복잡성 지표가 쓰기 능력 발전의 표준이 된다는 Biber 외(2011)의 연구 결과와는 상반된다.

본 연구는 자동화된 통사 구문 분석 프로그램인 TAASSC를 활용하여 통사적 복잡성 지표와 분석적 척도의 언어 사용 점수 간의 관계를 살펴본다. 본 연구에서는 ICNALE 코퍼스에서 영어를 외국어로 학습하는 EFL 학생이 작성한 에세이 440개를 분석하였고, 언어 사용 점수와 Lu의 전통적인 통사적 복잡성 지표, 구 복잡성 지표, 절 복잡성지표 간의 관계를 탐색하였다. 단계적 회귀분석 결과, 구 복잡성 지표가 분석적 척도의 언어 사용 점수를 가장 잘 예측하는 것으로 나타났으나 선행연구와는 달리 언어 사용 점수를 차지하는 변량은 낮았다. 본 연구결과를 토대로 구수준에서의 통사구문에 대한 지도와 연습이 필요하다는 쓰기 교육의 시사점을 제시한다.

The majority of research on Automated Writing Evaluation (AWE) programs has focused primarily on Grammarly, whereas QuillBot and its use in English as a Foreign Language (EFL) classrooms remains limitedly explored. This study examined the effectiveness of using QuillBot on the writing quality of college students. A total of 26 participants took pre- and post-writing tests, and four analytical tools were applied to assess their writing quality in terms of syntactic complexity, lexical diversity, lexical richness, and readability. Results of the syntactic complexity analysis across the four indices demonstrates that the syntactic complexity of EFL writing increased significantly, and substantial differences were observed in lexical richness and readability. These results suggest that QuillBot can compensate for the drawbacks of Grammarly and assist EFL writers in improving their overall writing quality.

본 연구는 선형 혼합 모형을 활용하여 쓰기 능력이 장기적으로 어떻게 발전되어 가는지를 통사적 복잡성(syntactic complexity) 측면에서 4명의 사례 연구자들이 작성한 에세이를 활용하여 분석하였다. 사례 연구자들은 자발적으로 Criterion 이라는 자동 쓰기 평가 프로그램의 피드백을 받아 초안과 수정본을 교실 밖에서 매달 한 개 씩 일 년 동안 작성했다. 총 48개 초안 에세이가 본 연구의 분석 대상이고, 통사적 복잡성은 Syntactic Complexity Analyzer의 14개 지표 중에서 추출하여 분석하였다. 선형 혼합 모형 분석 결과를 살펴보면 다음과 같다. 시간과 T-unit의 평균길이 간에는 통계적으로 유의미한 선형 관계가 있었으며, 이는 연구 참여자들이 시간이 지날수록 길이가 긴 T-uni을 포함한 에세이를 작성했음을 보여준다. 또한 시간과 의존절과 독립절 간의 비율 간에도 통계적으로 유의미한 선형 관계가 있었는데, 이는 연구 참여자들이 일 년 동안 높은 비율의 의존절이 포함된 에세이를 작성했음을 시사한다.

This longitudinal study analyzed syntactic development (Complexity, Accuracy, and Fluency; CAF) of six L2 Korean learners in a natural learning context. The learners recalled the stories of a short animated video through speaking and writing every 3 months, from month 0 to 15. The learners' responses were analyzed for a series of CAF measures and their cognitive, psychological, and social variables were investigated. The results showed that (i) L2 Korean learners' speaking and writing in various time periods showed significant differences in spoken and written accuracy, and complexity; (ii) the correlation between spoken and written complexity, spoken and written accuracy, as well as spoken and written fluency were significant, and (iii) the regression analysis showed that learners' cognitive, social, and psychological variables have significant effect on the L2 Korean syntactic development. The current study reports that L2 Korean learners engaged in self-learning in a natural learning environment without formal instruction made significant syntactic development.

With the wide spread of the Common European Framework of Reference (CEFR) scales, many studies attempt to apply them in routine teaching and rater training, while more evidence regarding criterial features at different CEFR levels are still urgently needed. The current study aims to explore complexity features that distinguish and predict CEFR proficiency levels in oral performance. Using a quantitative/corpus-based approach, this research analyzed lexical and syntactic complexity features over 80 transcriptions (includes A1, A2, B1 CEFR levels, and native speakers), based on an interview test, Standard Speaking Test (SST). ANOVA and correlation analysis were conducted to exclude insignificant complexity indices before the discriminant analysis. In the result, distinctive differences in complexity between CEFR speaking levels were observed, and with a combination of six major complexity features as predictors, 78.8% of the oral transcriptions were classified into the appropriate CEFR proficiency levels. It further confirms the possibility of predicting CEFR level of L2 learners based on their objective linguistic features. This study can be helpful as an empirical reference in language pedagogy, especially for L2 learners' self-assessment and teachers' prediction of students' proficiency levels. Also, it offers implications for the validation of the rating criteria, and improvement of rating system.

The purpose of the present study was to investigate the effect of syntactic complexity (sentence length and sentence structure) on sentence repetition performance and intelligibility between specific language impairment (SLI) and normal children. Thirteen SLI children and twenty-six normal children, matched by 3 years of language, participated in this study. The sentence repetition performance of the subjects were analyzed based on the sentence length (3-word simple sentences and 5-word simple sentences) and sentence structure (5-word simple sentences, 5-word conjoined complex sentences, and 5-word embedded complex sentences). The results of this study indicated the sentence structure influenced sentence repetition performance and intelligibility of SLI children only. The implication of these findings were discussed.

This study investigated the correlation between learners' psychological and social factors and their syntactic complexity of speaking. The study collected samples of Korean spoken production of 61 learners with English, Chinese, Japanese and other L1 backgrounds and applied mini-TOPIK, mini-AMTB, and SASIQ for 70 minutes. The study found that: (i) integrative motivation showed positive correlation with a number of simple complex clauses, but instrumental motivation correlated negatively with a number of adverbial clauses, indicating that high motivation hindered producing highly complex clauses although it triggered producing simple complex clauses, (ii) social contact with L2 native speakers showed positive correlation with general L2 development and a number of simple complex clauses, but revealed negative correlation with double or triple complex clauses, (iii) hours of L2 listening showed very strong positive correlation with producing triple complex clauses and general proficiency, but indicated negative correlation with a number of simple complex clauses. The study reported that high motivation toward Korean learning and active social activities with Korean native speakers helped produce simple complex clauses while hours of listening to Korean helped produce triple complex clauses.

본 연구는 한국인 학습자의 어휘복잡성 및 구문복잡성에 대해서 알아보았다. 이를 통해 이들의 한국어 실제 능력을 알아보며, 이를 토대로 이들에 대한 한국어 지도 방향을 설정하기 위해 실시하였다. 연구 결과 첫째, 국적에 따른 어휘복잡성 및 구문복잡성에는 유의한 차이가 나타나지 않았다. 둘째, 한국어 학습기간에 따른 어휘복잡성과 구문복잡성을 살펴본 결과 어휘복잡성의 하위 변인 중 다른 낱말 수에서 통계적으로 유의한 차이가 나타났으나, 구문복잡성의 하위 변인에서는 유의한 차이가 나타나지 않았다. 셋째, 한국거주기간, 한국어학습기간 및 언어 관련 변인들과의 상관을 살펴본 결과 한국어 학습기간과 TTR을 제외한 다른 변인들은 유의한 상관을 보였다. 연구결과에 따른 융합적 관점에서 한국어 학습자들을 위한 교육적 방향에 대하여 논의하였다.

In problem solving education, sentence problems are a tool for comprehensive evaluation of mathematical ability. The sentence problems refer to the problem expressed in sentence form rather than simply a numerical representation of mathematical problems. In order to solve sentence problems with a mixture of mathematical terms and general language, problem-solving ability including the ability to understand the meaning of sentences as well as the mathematical computation ability is required. Therefore, it is important to analyze syntactic elements from the linguistic aspects in sentence problems. The purpose of this study is to investigate the complexity of sentence problems in the length of sentences and the grammatical complexity of the sentences in the depth of the sentences by analyzing the 51 sentence problems presented in the $4^{th}$ grade mathematics textbook(2015 revised curriculum). As a result, it was confirmed that it is necessary to examine the length and depth of the sentence more carefully in the teaching and learning of sentence problems. Especially in elementary mathematics, the sentence problems requires a linguistic understanding of the sentence, and therefore it is necessary to consider syntactic elements in the process of developing and teaching sentence problems in mathematics textbook.
