The present study aimed to analyze the developmental trajectories of English achievement and exposure time through private education, utilizing univariate and multivariate latent growth curve analysis. This study used a subset of the Gyeonggi Education Panel Study data from 2012 to 2017. The results indicated consistent disparities in the growth of English achievement, depending on the student’s proficiency levels at the starting point. In particular, the early exposure to private tutoring was significantly and closely related to the initial status and the growth trajectory of English achievement. When the sample was classified by urbanicity, the findings suggested that the gap in English achievement was likely to increase over time across the two regions, with a stronger correlation with private tutoring found in urban areas. These results underscore the need for educational intervention for students in less advantageous conditions, and they provide valuable pedagogical implications for teaching English in the Korean EFL context.

This study addresses the scarcity of research examining technology’s impact on learners of English as a foreign language in English for specific purposes (ESP) courses within English-medium instruction (EMI) programs. Focusing on a business communication course using a social question-answering platform, this study explores the interplay among English proficiency, motivational orientations, and online engagement. Surveying 126 university students via a mixed-method approach, this research identifies distinct motivational orientations (intrinsic, extrinsic, and self-efficacy) existing during class activities, influenced by proficiency levels, with notable differences in online participation between beginner and advanced learners. The findings suggest that while online activities enhance peer interaction and teacher feedback, they may trigger anxiety in beginners, potentially diminishing motivation and self-efficacy. These results emphasize the need to tailor technology integration to proficiency levels and motivational orientations in ESP/EMI settings. Practical recommendations are offered for educators aiming to implement effective online activities and provide targeted support, particularly for beginner learners, thereby bolstering their motivation and selfefficacy.

The present study aimed to explore how pre-service teacher’s individual regulatory focus orientation, currently emerging as an interesting learner variable for language learning, could influence their Englishspeaking abilities. English teaching demonstration videos of 67 pre-service teachers were analyzed in terms of pronunciation, accuracy, and fluency. The regulatory focus orientations of participants were evaluated using a questionnaire. The results of data analysis, using multiple regression analysis, indicated that promotion-focus orientation was a significant positive predictor for pronunciation, fluency (words per minute, ratio of dysfluency), and accuracy (lexical errors, ratio of error-free AS-units). On the other hand, prevention-focus orientation did not emerge as a statistically significant factor affecting accuracy. However, it was observed to have a negative influence on both pronunciation and fluency. In light of the research findings that highlight the favorable impact of a promotion-focus orientation, suggestions were made for future teacher training programs aimed at enhancing the English proficiency of pre-service teachers.

This study compared Korean adult learners’ English speech in dialogic and monologic tasks, measuring 57 college students’ oral proficiency in terms of holistic and analytic grades. The statistical analyses were focused on two questions: 1) how much do the holistic grades of oral proficiency and analytic grades of the four linguistic features function differently across the tasks? and 2) which linguistic feature has the strongest correlation with the holistic grades of English oral proficiency? The study found significant differences between the two tasks in five aspects (English oral proficiency, topic development, fluency, range, and accuracy). It also showed that a monologic task resulted in lower achievements in those five aspects. In the comparison of the correlations with English proficiency, the range reached the top in both tasks, followed by topic development. The study provides some helpful information regarding which types of speech tasks and linguistic features of EFL oral proficiency are more desirable for targeting in teaching and assessment.

This study examined how Google Jamboard-based autonomous knowledge-sharing advanced language proficiency and motivation in an online intermediate–high EFL communication course. For one semester, 30 Korean first-year college students shared their learning experiences beyond the classroom, enhancing their English communication competence via a weekly Jamboard. The students speaking and perceived proficiencies and motivation changes were examined. Overall speaking proficiency increased, except for pronunciation. Students acquired the ability to selfstudy, but this was insufficient for oral practice because distance learning limited direct interactions. Perceived current proficiency increased, but imaginary proficiency and English importance did not. Their ease in using English in their daily life improved, and they felt the gap between the current and imaginary proficiencies decreased. The ideal L2 self increased, based on instrumentality and integrativeness. This finding indicates that students understood that they were undergoing the process of becoming fluent English speakers. Hence, well-organized self-directed activities can promote autonomous learning behavior to improve language proficiency and motivation.

To investigate L2 adolescent learners’ use of machine translation (MT), an MT error correction (EC) test was developed, based on the analysis of MT errors arising from translating the learners’ L1 of middle school EFL textbooks. Learners were also asked to report on their use of MT EC strategies on the EC task. Results indicated that mistranslated sentence and verb tense are the most difficult types of MT errors to correct. Furthermore, to resolve MT errors, guessing from context and literal translations were the two most frequently employed EC strategies. When multiple regression analysis was conducted to examine the contribution of EC strategies to the learners’ ability to correct errors, the mid proficiency learners’ reliance on literal translations and the low proficiency learners’ use of multiple EC strategies were positively associated with improved corrections of MT errors. The results of the study are discussed in light of how L2 learners need to develop competence for using MT in L2 writing.

The purpose of this study is to present a diagnostic evaluation tool that can more accurately determine the academic performance level in Korean language proficiency of foreign undergraduate students studying at domestic universities. The diagnostic evaluation diagnoses the academic Korean language proficiency of foreign undergraduates, and provides the diagnosis results to foreign undergraduates, professors, and university institutions so that teaching activities can be conducted efficiently. In this study, it was considered that the ‘Basic Academic Ability Diagnostic Test for the Korean Language Subject' was suitable as a test tool for diagnosing to diagnose the academic achievment of foreign undergraduates. This diagnostic test is a diagnostic tool designed for Korean students in Korea, and it not only continuously verifies its reliability and validity, but also includes background knowledge that Korean university students in Korea are basically acquiring. To prove that the 'Basic Academic Ability Diagnostic Test' is suitable as a diagnostic evaluation tool for foreign undergraduates, the correlation with the Korean language achievement evaluation was analyzed. The correlation between diagnostic evaluation and other items showed a significantly positive correlation. When the diagnostic evaluation score was good, the pre-test and post-test scores of Korean language proficiency, and the TOPIC level was also high. This result proves that the basic academic ability diagnostic test tool is very suitable as a diagnostic evaluation tool for foreign undergraduate students. Also, the analysis result of the pre- and post-tests and the TOPIK test showed a very significant and strong positive correlation with the post-test, and the higher the TOPIK grade, the higher the score of the pre‐test.

The purpose of this study is to determine whether the use of artificial intelligence (AI) improves English listening and reading proficiency. It focuses on whether its impacts differ by gender and major. The study was conducted in 2020 with 340 freshmen students in Korea. There were 182 male and 208 female students. The participants majored in different areas: 139 students majoring in aeronautics, 130 students studying policing and safety, 121 students studying in the arts department. The TOEIC test was adopted as pre- and post-tests to explore the impacts of using AI on English learning. To analyze the data, two-way ANOVAs were administered. The study found no interaction effects of gender or major on either listening and reading proficiency. However, gender and major, respectively, had significant impacts on listening. Regarding reading proficiency, major alone affected the students’ performance. Based on these findings, pedagogical implications are considered.

본고에서는 한국어능력시험 듣기 텍스트에 나타난 비동 의 화행 전략의 출현 빈도 및 구체적 양상을 다각도로 분석하여 전략 사용의 효용성 및 교육적 함의를 고찰하였다. 비동의 화행 전략 실현 빈도는 ‘간접 비동의 전략’, ‘직접 비동의 전략’, ‘부가 전략’의 순으로 나타났으며, 세부 전략들은 다른 전략과의 결합을 통해 실현되는 경우가 많았다. 세부 전략 실현 빈도의 경우 ‘간접 비동의 전략’ 에서는 ‘설명’, ‘직접 비동의 전략’에서는 ‘완곡한 주 장’, ‘부가 전략’에서는 ‘부분 수용’이 가장 높게 나타났다. 비동의 화행의 전략적 사용은 한국어 학습자의 정교한 대화 협력을 위한 중요한 요소가 될 수 있다. 따라서 한국어능력시험에서도 실제성 이 반영된 비동의 화행을 제시할 필요가 있으며 교육 현장에서도 학습자들이 비동의 상황에서 성공적인 화행을 수행할 수 있도록 다양한 비동의 화용 전략을 교육할 필요가 있을 것이라 본다.

The purpose of this study is to compare the effects of input- and output-based planning (reading a sample passage vs. writing a draft) on the oral performance of L2 learners with low-proficiency. In this study, 16 Korean female junior college students of low English proficiency were divided into two different planning groups. The reading group was required to read a sample passage of the given topic, designed to encourage “noticing” and “focus on form” using input enhancement, while the writing group was asked to write a draft of their speech, using only their own L2 knowledge. After such planning activities, both groups recorded their assigned speaking tasks using Kakao Talk. Eight planning activities and oral performances were completed over the period of the semester. In order to compare the effects of input- and output-based planning on the improvement of overall proficiency, pre- and post-tests, in which the students produced the same narratives, were analyzed using Mann-Whitney U and Wilcoxon signed-rank tests. Furthermore, this study explored any difference in speaking performance after each type of planning and what the learners were actually doing during planning time. The results showed that output-based planning had positive effects on speaking performance and its repeated practice led to the improvement of overall proficiency.

This study investigates the claim that task-induced involvement load has an effect on vocabulary learning and examines the effect of task types and word concreteness on intentional vocabulary learning in the Korean EFL context. This study aims at testing whether productive word-focused tasks lead to equally effective vocabulary learning when the total involvement load index is equal but the distribution of index levels of each component (need, search, and evaluation) is different. The three productive word-focused task types are gap-fillig, sentence writing, and gap-filling through word transformation. In addition, in order to investigate the effect of word concreteness on vocabulary learning, two groups of target words were selected based on the level of word concreteness. In sum, the results of this study generally supported involvement load hypothesis (Laufer & Hulstijin, 2001) and test types and proficiency levels proved to be important variables that affect vocabulary learning. Moreover, the findings also indicated that word concreteness was not a major factor in vocabulary learning. The pedagogical implications and further suggestions are discussed.

The study investigated the effects of recasts and prompts on learning language forms that arose incidentally in dyadic interaction, focusing on the degree of explicitness of each type of feedback and learner proficiency levels. The data were collected from 64 beginning and upper-intermediate English learners of Korean. Thirty-one beginning learners were randomly assigned to a feedback group and to a control group, and thirtythree upper-intermediate learners were also assigned to a feedback group and to a control group. Each learner was paired with an English speaker and worked on a picture-sequencing task. The learners in the feedback groups received recasts or prompts on their erroneous utterances while the learners in the control groups did not. The effects of feedback were measured by pre-interaction picture descriptions and immediate and delayed post-interaction correction tasks. The study found that both recasts and prompts had some effects on learning the targeted forms, and more explicit forms of each feedback resulted in a higher rate of correction. The beginning learners took more advantages of recasts relative to the upper-intermediate learners, and explicit prompts worked better for the upper-intermediate learners. The effects of prompts sustained longer than recasts in both levels.

This study aims at investigating 1)the perception of international students' mother tongue and Korean language, 2)whether their perception differs with the degree of Korean proficiency, and 3)whether the degree of exposure to Korean can affect Korean proficiency. Eighty nine international students participated in a questionnaire survey. The overall results on the survey showed that the international students' perception of their mother tongue was strong in general. However, interesting findings were that the participants' level of Korean proficiency was closely related to the perception of mother tongue: the participants who had a low level of Korean proficiency showed a comparatively strong perception of mother tongue. Furthermore, the perception of Korean language was weaker compared to that of their mother tongue. However, the exposure to Korean(e.g. the frequency of using Korean) playing a role in improving Korean proficiency was observed. Therefore, this study suggests that acquiring Korean can be related to the perception of mother tongue and that the international students should raise the frequency of contact with Koreans for their Korean proficiency.

This study is a summary of the complex odor proficiency testing method using the air dilution sensory method conducted for the last 7 years. Results of the homogeneity and stability test were obtained from the measurement of the standard sample for identifying the range of measurable concentration so that the complex odor proficiency testing method was established through processing the manufactured standard sample and distribution method. Standard samples were prepared using a large Teflon bag after being homogeneously mixed inside a Teflon bag. Also, a distributing container was selected with a polyester aluminum bag in order to avoid samples of the best condition from being contaminated during transport as well as being exposed to invasive odor from a sampling bag. Test results revealed that the mixture of toluene and m-Xylene was most appropriate for this proficiency testing method to the homogeneity and stability of the testing method. In addition, DMS and DMDS were the optimized samples at the outlet area. As a result, the standard method was established to address the analysis quality management to the mixed odor inspection agencies in Korea.

This paper explores the English needs of culinary college students in Korea, asking whether their English needs differ by their desired careers. To this end, we administered a survey to 123 culinary college students and divided them into six groups based on their desired careers. The results show that the type of desired career of the participants is highly correlated with their perceived need for learning English, the kind of English skills that they want to learn, and the level of English proficiency that they hope to achieve. For example, students planning to work for a restaurant or hotel abroad had the highest English proficiency needs whereas those planning to study in graduate school in Korea and those planning to work for a restaurant or hotel in Korea had relatively lower needs. The results suggest that college English programs need to provide diverse college English courses to prepare students for their diverse future careers.

The study investigates to what extent a commitment to and a self-evaluation of a specific self-directed learning activity explain Korean college students’ EFL proficiency (using TOEIC reading scores). Of the Korean college students who participated, 52 completed log writing of self-directed learning activities, and 44 completed a self-evaluating survey and submitting a TOEIC reading score. Through statistical analyses, including correlations and regressions, the study finds that the number of minutes spent on reading aloud explained 10% of the variances of participants’ TOEIC reading scores. Another finding of the study is that perceived effectiveness of note-taking for grammar learning on listening and perceived manageability of reading aloud explained 21% of the variances in TOEIC reading scores. On the basis of these results, the study proposes that commitment to reading aloud and learner-perceived effectiveness of note-taking for grammar learning on listening can function as significant predictors for EFL reading proficiency. Several practical suggestions are provided for EFL instructors and researchers for the more effective use of self-directed learning activities and self-evaluation results.

Linguistic features that are indicative of higher writing proficiency levels can inform many aspects of lanauage assesment such as scoring rubrics, test items, and automated essay scoring(AES). The recent advancement of computer algorithms that automatically calculate indicates based on various linguistic features has made it possible to examine the relationship between linguistic features and writing proficiency on a larger scale. While the ability to use appropriate n-grams - recurring sequences of contiguous words - has been identified as a characteristic differentiating between proficiency levels in the literature, few studies have examined this relationship using computational indices. To this end, this study utilized the Tool for the Automatic Analysis of Lexical Sophistication(TAALES;Kyle&Crossley, 2015) to calcualte eight indices based on n-grams from a stratified corpus consisting of 360 argumentative essays written by Korean college-level learners. First, the indices from the training set of 240 essays were used to design a multinomial logistic regression model in order to identify indices that are significant predictors of writing proficiency levels. Subsequently, the regression model was applied to a test set of 120 essays to examine whether the model could be used to predict the proficiency levels of unseen essays. The results revealed that the mean bigram T, mean bigram Delta P, mean bigram-to-unigram Delta P, and proportion of 30,000 most frequent trigrams indices were significant predictors of proficiency levels. Furthermore, the regression model based on eight indices correctly classfied 52.5% of essays in the test set, demonstrating above-chance level accuarcy.

In this study, the homogeneity and stability of standard samples for proficiency testing in indoor air quality within the country (formaldehyde, benzene, toluene, ethylbenzene, p-xylene, styrene, TVOC) were evaluated. The procedures and statistical analysis methods applied in ISO/IEC 13528 (2009) and KS A ISO Guide 35 (2005) were applied as evaluation methods. The homogeneity evaluation was a statistical analysis of repeated measurements of each of the 11 ports and between the 11 ports concentration data. As a result, the coefficient of variation (CV) was within the range of 1.9%~5.9%. The difference between the ports was found to be insignificant and met the statistical standard specified in KS Q ISO 13528. The stability evaluation was assessed by the change in concentration over the long-term stability of the standard samples stored for 90 days. The coefficient of variation (CV), which was within the range of 2.6%~9.0%, exhibited changes in the concentration of the long-term stored standard samples. However, the results satisfy the statistical standard specified in KS A ISO Guide 35. Overall, there is no significant difference between the homogeneity of the standard samples by the port and the stability of the long-term stored samples. Therefore, it is considered to be an appropriate method to supply standard samples in an indoor air quality proficiency test.
