This research investigates listening strategies and the relationship between the employment of strategy and listening proficiency of Korean EFL middle school students. One hundred and four middle school students (N = 104) participated in this study and their strategy use was assessed through a questionnaire adapted from Oxford's (1990) SILL and O'Malley and Chamot (1990). To measure listening proficiency, the English Listening Ability Test designed by 15 city and provincial offices of education in Korea was used. The results show that students employed a moderate use of strategies; compensation strategies were used most frequently and metacognitive strategies were used the least frequently. Significant differences were found in the use of implicit strategy among different listening proficiency groups, but not in their use of behavioral strategy. Furthermore, there were significant differences in the use of implicit memory, cognitive and compensation strategies among groups of students with different listening proficiencies, but not in their use of metacognitive strategy. The results from multiple regression analysis indicate that implicit strategy use could play an important role in listening comprehension. The findings suggest the need for additional research to explore the effect of listening strategy training for English language learners.

The goal of the current study is to investigate whether L2 learners' perceptual ability regarding epenthetic vowels is interconnected with other aspects of speech recognition, such as lexical stress, sentence focus, and vowel recognition. Twenty-five Korean L2 learners of English participated in perception experiments assessing vowel epenthesis oddity, lexical stress oddity, sentence focus oddity, and vowel identification. Results indicate that accuracy on the vowel epenthesis oddity test is influenced by both lexical stress and sentence focus, suggesting that perceptual ability regarding epenthetic vowels is influenced by the acquisition of L2 rhythmic structure at both word and sentence levels. Additionally, this study identifies a proficiency effect on vowel epenthesis recognition, implying that the influence of L1 phonotactics diminishes as L2 proficiency increases. Taken together, this study illustrates the interaction between perceptual abilities in vowel epenthesis and prosodic stress in the field of L2 speech perception.

언어는 문화화 연결되어 있을 뿐만 아니라 한 개인을 사회적이고 문화적인 차원에서 통합하는 기능을 지니고 있다. 사회적 참여활동 또한 이민자를 포함한 한 개인의 정체성을 신장하는데 중요한 역할을 수행하는 것으로 여러 선행연구들이 주장하고 있으나 이를 경험적으로 규명한 연구는 제한되어 있다. 이러한 측면에서 이 연구는 한국 농촌사회에 거주하는 결혼이민여성들이 인식한 자신들의 공동체 의식 수준에 한국어 능력 수준 및 지역사회활동 참여 경험과 같은 변인들이 어떠한 영향을 미치는가를 규명하려 하였다. 이러한 연구목적을 규명하기 위해 구조화된 설문지를 이용해 최종적으로 전국 43개 지역에서 조사된 356명의 자료가 분석되었다. 연구결과에 의하면 한국어 능력수준 변인은 결혼이민여성들이 인식한 그들의 공동체의식 수준에 중요하고 의미있게 작용하는 반면 지역사회활동참여 경험 변인은 그것에 대해 매개적인 효과만을 지니는 것으로 나타났다. 또한 한국어 능력수준변인은 지역사회활동참여 경험 변인보다 상대적으로 중요한 설명력을 갖는 것으로 나타나, 결혼이민여성들의 공동체 의식을 향상하기 위해서 지역사회활동이 한국어 능력을 향상하는 프로그램과 병행하여 실시되어야 할 것으로 보인다. 이외에도 본 연구결과에 토대하여 결혼이민여성들의 한국어 능력과 지역사회활동 참여를 통해 공동체 의식을 향상하는 몇가지 방안들이 결론 및 제언부분에 제안되어 있다.

영어 능력평가를 위한 테스트는 평가자, 과제, 인터뷰의 주제, 그리고 평가 받는 사람의 성별 등 여러 가지 이유 때문에 그 평가 결과가 아주 다양할 수 있다. 이전의 자료는 평가자가 외국어로서의 영어구술 능력 평가 결과에 아주 중요한 영향을 끼친다는 것을 증명해 왔다. 이렇게 영어 능력 구술 평가에 영향을 미치는 평가자에 대한 많은 조사는 있었지만 평가 과정에 잠재적으로 영향을 줄 수 있는 평가자의 가변성에 대한 조사는 극히 드물었다. 시험 환경이 달라지면 그에 따라 구술 평가가 달라지고 그 평가 기준은 또 완전히 달라진다. 그러므로 다양한 시험 수행 과제에 대해 똑같은 평가 기준을 적용하는 것은 적당치 않다. 즉 평가 과정에 대한 더 많은 원안 분석과 심도 있는 연구가 필요하다. 제 2외국어로서 영어 능력평가를 위한 구술시험은 보다 더 현실적이고 효율적인 장치가 만들어져야 할 것이다.

The purpose of this study was to investigate the effect of the use of video resources on improving listening comprehension. 86 students enrolled in a summer session at a Korean university participated in the study. They were assigned to one of three groups based on the results of their TOEIC test scores: 29 students were assigned to the low group, 29 students to the intermediate group, and 28 students to the advanced group. Each group studied the same lessons using authentic video materials. They were taught for 10 sessions over three weeks. The pre- and post-test design helped to determine whether authentic videos were effective in improving listening skills for all proficiency levels. In addition, a questionnaire investigated students' perceptions toward using video resources. Paired sample t-tests, ANOVAs, and an ANCOVA were utilized to identify significant differences. It was concluded that in the intermediate and advanced proficiency groups, the students' listening skills increased significantly after learning with videos. In addition, listening improvements among the intermediate and advanced students were much greater than those of the low proficiency group. As for students' perceptions toward using video resources for improving their English listening skills, they responded positively. Based on these findings, pedagogical implications are suggested, and future studies will be discussed.

This study explored how Korean L2 learners of English utilize multiple acoustic cues (VOT and F0) in perceiving and producing the English alveolar stop with a voicing contrast. Thirty-four 18-year-old high-school students participated in the study. Their English proficiency level was classified as either 'high' (HEP) or 'low' (LEP) according to high-school English level standardization. Thirty different synthesized syllables were presented in audio stimuli by combining a 6-step VOTs and a 5-step F0s. The listeners judged how close the audio stimulus was to /t/ or /d/ in L2 using a visual analogue scale. The L2 /d/ and /t/ productions collected from the 22 learners (12 HEP, 10 LEP) were acoustically analyzed by measuring VOT and F0 at the vowel onset. Results showed that LEP listeners attended to the F0 in the stimuli more sensitively than HEP listeners, suggesting that HEP listeners could inhibit less important acoustic dimensions better than LEP listeners in their L2 perception. The L2 production patterns also exhibited a group-difference between HEP and LEP in that HEP speakers utilized their VOT dimension (primary cue in L2) more effectively than LEP speakers. Taken together, the study showed that the relative cue-weighting strategies in L2 perception and production are closely related to the learner's L2 proficiency level in that more proficient learners had a better control of inhibiting and enhancing the relevant acoustic parameters.

The current study investigates whether Korean-speaking adults show differential sensitivities to the sources of auditory stimuli (L1 Korean and L2 English) in utilizing VOT and f0 in the perceptual mode of L2 stops, and how the L2 proficiency interacts with the learners' low-level phonetic sensitivities in L2 perceptual mode. 48 Korean learners of English participated in the perception experiments where they rated the goodness of English /t/ and /d/ using an analogue scale. Two sets of stimuli (English and Korean sources) were prepared by manipulating VOT (6-steps) and f0 (5-steps) values of productions by an English male (L2 source condition) and a Korean male (L1 source condition). Findings showed that, in judging /t/-likeness, the listeners responded differently to the two auditory stimulus conditions by relying on VOT significantly more in English source condition than in Korean source condition. The listeners' English proficiency did not interact with these differential sensitivities to the auditory stimulus source either along the VOT dimension or the f0 dimension. The results of the current study suggest that low-level contextual information of the auditory source can affect the learners in faithfully being in the L2 perceptual mode.

The study examined the effects of explicit derivational morphology instruction (henceforth DMI) on the incidental vocabulary acquisition and reading comprehension of 132 Korean 1st-year high school students who responded to a battery of tests (two vocabulary tests and a reading comprehension test). Multiple statistical tools were used to analyze the data: Analysis of Covariance (ANCOVA), Analysis of Variance (ANOVA), Simple Regression Analysis, Tests of Simple Main Effects, and effect size computation using Cohen's d. The results indicated that (a) DMI enhanced students' ability to infer word meanings in context, (b) DMI promoted high proficiency students' reading comprehension, whereas it impeded intermediate proficiency students' reading comprehension, (c) vocabulary knowledge has a strong positive predictive value for reading comprehension, and (d) the gaps of vocabulary knowledge across proficiency levels were still substantial, despite the observation that DMI promoted students' vocabulary acquisition. These results have a bearing on English as Foreign Language (EFL) reading pedagogy.

The present study aims to investigate neural activations according to the level of code switching in English proficient bilinguals and to find the relationship between the performance of language switching and proficiency level using ERPs (event-related potentials). First, when comparing high-proficient (HP) with low-proficient (LP) bilingual performance in a native language environment, the activation level of N2 was observed to be higher in the HP group than in the LP group, but only under two conditions: 1) the language switching (between-language) condition known as indexing attention of code switching and 2) the inhibition of current language for L1. Another effect of N400 can be shown in both groups only in the language non-switching (within-language) condition. This effect suggests that both groups completed the semantic acceptability task well in their native language environment without the burden of language switching, irrespective of high or low performance. The latencies of N400 are only about 100ms earlier in the HP group than in the LP group. This difference can be interpreted as facilitation of the given task. These results suggest that HP showed the differential activation in inhibitory system for L1 in switching condition of L1-to-L2 to be contrary to inactivation of inhibitory system for the LP group. Despite the absence of an N400 effect at the given task in both groups, differential latencies between the peaks were attributed to the differences of efficiency in semantic processing.
