  • Due to frequent international exchanges, there has been much emphasis on communication proficiency in foreign language education. However, when we look back upon teaching English in Korea over past years, we find that English teaching has been dominated mainly by Grammar-Translation Method, which makes teachers and students pay little attention to listening skill that is regarded as the basis of communication proficiency. Recently many English teachers have shown their interest in listening skill, so they come to use the textbook record tapes to improve listening skill. But listening training by textbook record tapes seems to make students feel bored. So the purpose of this study is to suggest an effective way of improving listening skill by means of Pop Songs that the students are indulged in. The processes of this study consist of three stages : 1) listening to songs, 2) explanation about structures and vocabularies in songs, 3) filling in blanks while listening. The subjects in this study are freshmen 88 students in girls' High School They are grouped into two : one is experimental group and the other control group. Among the subjects, the former have been taught by the lesson plan using pop songs, while the latter by the lesson plan using textbook record tapes. The experiment lasts about 9 months (from March to November, l994) The data for analyzing the study results have been collected from two kinds of tests : one is listening test and the other comprehensive test. The hypothesises of this study areas follows : 1) Depending on hearing materials (experimental material vs traditional material), there will be a difference in scores of listening skills between EG (experimental group) and CG (control group), 2) Depending on the interest on pop songs, there will be a difference in scores of hearing skills in CG, 3) Depending on hearing material. there will be a difference in scores of overall English skills between EG and CG, 4) Improvement in listening skill will give influence on the overall English scores. The findings of this study indicate that pop songs are effective to improve students' listening skill, that students' interest in the hearing material is important, and that listening skill is closely related to other skills, especially reading skill. It can be concluded that English teachers should make efforts to find the suitable listening materials which will help students to improve their listening proficiency effectively.

  • This study attempts to supplement what is known about the influence of prior knowledge on second language listening comprehension. To do so, the study examines the effect of prior knowledge and language proficiency on the ability of L2 listeners to understand texts. The purpose of an experiment was to determine the effect of topic familiarity on the L2 listening comprehension ability of subjects who varied in L2 listening proficiency level. The subjects (N=117) were selected from a population of college students enrolled in the Departments of English and Business in Korea. English listening proficiency levels were designated on the basis of TOEFL listening scores. Subjects listened twice each to texts (more familiar and less familiar). After listening to each text, a ten-item objective test was administered to test the subjects' comprehension of the information presented in the text. Objective tests were analyzed. using repeated measures analysis. A post hoc test was conducted to identify the means that were significantly different. This study yielded the following results: (1) subjects with high prior knowledge comprehended texts significantly better than did subjects with low prior knowledge; (2) the level of L2 listening proficiency had a significant effect on the L2 listening comprehension of texts, but there was no interaction between prior knowledge and the level of L2 listening proficiency.

  • This study aims to uncover the learner's language proficiency shown in the writing data of Chinese elementary/intermediate level learners. Language proficiency of the learners acquired by error analysis provides only partial information, and thus this study analyses the interlanguage of Korean learners in terms of 'Mean Length of Utterance, MLU' to discover the overall aspect of learner's language proficiency more symmetrically. The analysis of vocabulary area is to be enforced after generally studying the learner's language development aspect in accordance with MLU-m(orpheme) and MLU-(w)ord found in compositions by Chinese speaking Korean language learners. In terms of MLU, it has been slightly increased as the level of proficiency between elementary level and intermediate level learners; however, the morpheme seemed to be difficult to use, since the difference between Chinese learners and Korean university students has been notably shown. Vocabulary diversity, using aspect for each word class, and using aspect of the predicate are studied for vocabulary area; more various and numerous vocabulary tend to be used as the level of proficiency increases. In terms of predicate use, Chinese learners use less numerous vocabulary types.

  • This paper presents the development of language tutoring systems for nonnative speakers by leveraging advanced end-to-end automatic speech recognition (ASR) and proficiency evaluation. Given the frequent errors in non-native speech, high-performance spontaneous speech recognition must be applied. Our systems accurately evaluate pronunciation and speaking fluency and provide feedback on errors by relying on precise transcriptions. End-to-end ASR is implemented and enhanced by using diverse non-native speaker speech data for model training. For performance enhancement, we combine semisupervised and transfer learning techniques using labeled and unlabeled speech data. Automatic proficiency evaluation is performed by a model trained to maximize the statistical correlation between the fluency score manually determined by a human expert and a calculated fluency score. We developed an English tutoring system for Korean elementary students called EBS AI Peng-Talk and a Korean tutoring system for foreigners called KSI Korean AI Tutor. Both systems were deployed by South Korean government agencies.

  • Purpose: On the basis of the theoretical framework of a combination of Roy's adaptation theory and Lazarus & Folkman's theory of stress - appraise coping, the purpose of this study was to predict effect factors of adaptation to university life of Chinese international students in Korea. After this, a model of adaptation to university life of Chinese international students in Korea was constructed. Methods: A questionnaire was used to survey 369 Chinese international students from one university in Korea, which was analyzed by using PASW Statistics 18.0 and LISREL 8.7. Results: This theoretical model explained adaptation to university life of Chinese international students at 75.0% in Korea. Physical symptoms, loneliness, acculturation stress and self-efficacy directly affected the adaptation to university life. Korean language proficiency indirectly affected adaptation to university life through self-efficacy. Conclusion: Results of this study provided theoretical basis for the future health care of university- centered health centers. For improving adaptation to university life of Chinese international students in Korea, education and nursing measures for reducing physical symptoms, loneliness and acculturation stress, and improving Korean language proficiency and self-efficacy are proposed for further research and development.

  • For the past 20 years the process approach to writing has been popular in second language writing classrooms. However, there have been very few studies conducted in Korea with regard to the composing processes and the effects of proficiency on writers' usage. The present study attempts to begin to fill this gap. Three groups of college students with different writing proficiency participated in the study: the advanced group, the intermediate group, and the beginning group. The verbal protocol of their writing processes revealed that they approached writing tasks differently. While the advanced writers focused on generating texts and ideas and examined their writing at both global and local levels, the other two groups of students tended to focus on evaluating text at the local level and generated fewer ideas and less text. The findings from this study are then compared to those of some major studies of the composing process as conclusions are subsequently drawn about the specific needs of Korean college writers.

  • This study examined the role of contextual knowledge in cross-cultural communication between non-native speakers on an interactive web with a bulletin board system through which college students of English at Japanese and Korean universities interacted with each other discussing the topics of local and global issues. The study investigated the influence of students' relative contextual knowledge on active participation in interactions and discussed the results focusing on the use of discourse strategies for meaning negotiation. The study argues that in interactions even between non-native speakers with limited proficiency, contextual knowledge in the topic under discussion affects the degree to which they accommodate to each other during communication and suggests that the focus of teaching English as a foreign language also should be given to what kind of contextual knowledge students need to obtain and how to express it rather than what level of proficiency in English they need to acquire.

  • This study examines how elementary students understand fractions with operations conceptually and how they perform procedures in the division of fractions. We attempted to look into students' understanding about fractions with divisions in regard to mathematical proficiency suggested by National Research Council (2001). Mathematical proficiency is identified as an intertwined and interconnected composition of 5 strands- conceptual understanding, procedural fluency, strategic competence, adaptive reasoning, and productive disposition. We developed an instrument to identify students' understanding of fractions with multiplication and division and conducted the survey in which 149 6th-graders participated. The findings from the data analysis suggested that overall, the 6th-graders seemed not to understand fractions conceptually; in particular, their understanding is limited to a particular model of part-whole fraction. The students showed a tendency to use memorized procedure-invert and multiply in a given problem without connecting the procedure to the concept of the division of fractions. The findings also proposed that on a given problem-solving task that suggested a pathway in order for the students to apply or follow the procedures in a new situation, they performed the computation very fluently when dividing two fractions by multiplying by a reciprocal. In doing so, however, they appeared to unable to connect the procedures with the concepts of fractions with division.
