The current study aims to investigate the relationship between working memory capacity, vocabulary size, and listening competence of Korean EFL (English as a Foreign Language) learners. 30 English education majors from a university in Korea were recruited. The backward digit span and the operation span tasks were used to measure the participants' working memory capacity, while the Listening Vocabulary Level Test (LVLT) and the Michigan English Test (MET) were employed to measure their vocabulary size and listening proficiency in English, respectively. The correlational analyses revealed that the bigger one's working memory storage was, the better the person processed incoming input. However, no statistically significant correlation was found between working memory capacity, English vocabulary size, and listening proficiency, possibly due to the small sample size and the homogeneous subjects.

Although vocabulary is one of the most important aspects in learning English, it is not dealt with as extensively as the grammar and reading comprehension in the classes due to time limitation. Furthermore, it is also dealt with in only a limited way at most of the English learning web sites compared to the other aspects such as grammar and reading comprehension. In this study. a web-based learning system for English vocabulary which allows a student to study the vocabulary before or after the classes by herself in order to supplement the English classes provided at school. Especially, it allows the students to learn the vocabulary within the context of sentences. It also provides an efficient structure for a repeated study of vocabulary that is new or difficult to the student.

This study explored the lexical sophistication features to distinguish the group membership of English proficiency, using the automatic analysis program of lexical sophistication. A total of 600 essays written by 300 Korean college students were extracted from the ICNALE (International Corpus Network of Asian Learners of English) corpus and a discriminant function analysis was performed using SPSS program. Results showed that the lexical features to distinguish three groups of English proficiency are SUBTLEXUS frequency content words, age of acquisition content words, lexical decision mean reaction time function words, and hypernymy verbs. High-level Korean students used frequent content words from SUBTLEXUS corpus to a lesser degree and produced more sophisticated words that can be learned at a later age and take longer reaction time in lexical decision task, and more concrete verbs.

영어로 진행하는 전공 수업, 영어로 쓰여진 교재의 사용 등이 빈번한 대학 수준 이상에서의 학업을 위해서는 학문목적영어와 관련된 능력을 갖추는 것이 필수적이다. 영어로 진행되는 공부에 어려움을 경험하는 학생들을 돕기 위해 많은 학자들은 해당 분야의 키워드, 즉 전문어휘 목록 작성을 통해 해당 분야의 어휘 학습을 돕는 것이 중요하다고 강조하고 있다. 이에 본 연구에서는 해당분야의 전문 어휘 추출과 관련한 핵심 개념과 선행연구를 살펴본 후, 각기 상이한 키워드 추출 방법을 채택한 2개의 선행연구를 통해 실제 키워드 추출이 이루어지는 방법 및 각각의 장단점에 대해 살펴보고자 한다.

본 연구는 공과대학 학생들이 배우는 전공영어로서의 특수목적영어(ESP)에 대해 코퍼스 기반 접근법의 유용성을 논하고자 한다. 이에 본 연구에서는 공과대학에서 사용하는 전공텍스트를 코퍼스로 구축하여 컴퓨터에 기반한 분석에서 나온 결과들을 제시하면서 공학영어 코퍼스의 특성을 살펴보고 궁극적으로 영어매개수업을 듣는 공대학생들의 데이터 기반 학습에 일조하고자 한다. 본 연구에서 사용된 목표 코퍼스는 세부전공과 상관없이 공통적으로 적용되는 공학과목을 선정하여 구축되었고 비교대상인 참조 코퍼스는 British National Corpus를 사용하였다. 공학영어 코퍼스는 총 단어 180만개, 단어 유형 만 6천여개로 이루어졌고 코퍼스 분석도구인 AntConc 3.4.4를 이용하여 빈도 분석과 키워드 분석이 수행되었다. 고빈도수 어휘의 분석결과 목표 코퍼스와 참조 코퍼스에서 가장 빈번하게 나타나는 어휘군은 내용어(content words)보다는 기능어(function words) 형태가 많다는 점이 나타났고 내용어군만 분석결과 참조코퍼스에 비해 공학영어 코퍼스에 과학영역의 변이어가 많이 분포하고 있음이 드러났다. 또한 키워드 분석에서는 공학영어 코퍼스의 키워드 동사군이 전문적인 어휘(technical vocabulary)보다는 비전문적인 학술적 어휘(non-technical academic vocabulary)가 상대적으로 많이 분포되어 있음이 드러나 ESP교육을 실시함에 있어서 전공관련 전문영어와 함께 일반적인 학술 영어에 대한 인식을 고양해야 할 필요성이 대두된다.

This paper aims to analyze English vocabulary of the North Korean textbooks diachronically using the constructed English textbook corpus. The North Korea English textbooks attained from Information Center on North Korea of the Ministry of Unification are divided into before and after Kim Jong-Il era for the year of 1996 in which the curriculum revision has been conducted. They are stored as text files to analyse vocabularies using WordSmith Tools 7.0. The vocabulary size of the revised textbooks increased after the curriculum reorganization, but the number of vocabulary types and vocabulary diversity decreased. After the curriculum revision, it was found that lots of vocabulary related to the establishment of the Kim Jong-Il system appeared as the keyword. It was also found that some vocabularies reflected the economic and social life of North Korea. In addition, through comparison of the 100 high-frequency word list and keywords, it can be concluded that the vocabulary of the English textbooks of North Korea is gradually changing into communicative contents from contents related with written language.

This study aims to functionally classify lexical bundles appearing in academic papers on nuclear science and engineering written in English and then analyze the lexical bundles' characteristics compared to those appearing in general academic papers. To this end, the texts of nuclear science and engineering papers were collected and produced as a corpus(c. 1 mil. tokens). Then they were statistically compared through Chi-square tests and standardized residuals with the corpus of general academic papers(c. 750,000 tokens). The results revealed that, compared to general academic papers, the bundles in the stance lexical bundle category were mainly used among the functional lexical bundle in nuclear science and engineering. The use of the lexical bundles lacked much variety. The same type of lexical bundles was 're-used' and 'recycled'. Based on these research results, educational implications for English for Academic Purposes and the further direction of follow-up research were discussed and suggested.

The convergence of mobile communications and handheld computers offers the opportunity to develop technology that will assist individuals and groups to learn anytime, anywhere. In this thesis, we suggest a learning model for educational mobile contents, and implement a mobile contents for English vocabulary learning. The mobile contents consist of two parts: vocabulary learning and vocabulary evaluation. The vocabulary learning provides the mobile learner not only the display of English vocabulary but also the pronunciation of native speaker. The degree of learning achievement is evaluated by the quiz program of game style. Accordingly, the proposed prototype system for English vocabulary learning is designed and implemented, as an exemplar of personal mobile systems for edutainment mobile learning.

The average acoustic distribution of American English speakers was statistically compared with the English-speaking patterns of gifted students in a Science Academy in Korea. By analyzing speech recordings, the duration time of which is much longer than in previous studies, this research identified the degree of acoustic proximity between the two parties and the predictability of English academic achievement of gifted high school students. Long-term spectral acoustic power distribution vectors were obtained for 2,048 center frequencies in the range of 20 Hz to 20,000 Hz by applying an long-term average speech spectrum (LTASS) MATLAB code. Three more variables were statistically compared to discover additional indices that can predict future English academic achievement: the receptive vocabulary size test, the cumulative vocabulary scores of English formative assessment, and the English Speaking Proficiency Test scores. Linear regression and correlational analyses between the four variables showed that the receptive vocabulary size test and the low-frequency vocabulary formative assessments which require both lexical and domain-specific science background knowledge are relatively more significant variables than a basic suprasegmental level English fluency in the predictability of gifted students' academic achievement.

The aim of this research is the development and evaluation of a technical vocabulary list for early childhood education. The list was compiled from a corpus of 500,000 running words of written academic texts from 7 books about early childhood education. The distribution of GSL[1] and AWL[2] was 81.86% and 9.78% respectively, which meant that academic texts related to early childhood education is very similar with ones on other disciplines. The technical vocabulary list for early childhood education (TV4ECE), extracted in terms of frequency and range, contains 224 types. This word list can be used to teach early childhood education in English, especially for the preparation of reading the English texts in the field of early childhood education.
