This study examined the effects of creating English picture books using generative artificial intelligence (AI) on Korean high school students’ reading and writing skills, AI literacy, and self-efficacy. Forty-five students were divided into two groups and participated in tasks that included selecting a character from English-speaking cultures, generating images using Bing Image Creator, drafting and revising stories with ChatGPT, and creating audiobooks with ClovaDubbing. Reading and writing skills were evaluated using pre- and post-tests, and AI literacy as well as affective factors, including selfefficacy, were measured through surveys. The results indicated a significant improvement in students’ writing skills and self-efficacy, whereas reading skills did not demonstrate statistically significant progress. The study underscores the potential of generative AI as a tool for enhancing writing skills, AI literacy, and self-efficacy in language learning. However, it also emphasizes the need for further pedagogical efforts to design instructional strategies that effectively improve reading skills. These findings offer practical guidance for integrating generative AI into EFL education to enhance language learning and AI literacy.

This study aimed to provide fundamental data that could guide high school students' night eating behavior by investigating habits of their night eating consumption during COVID-19 pandemic (From 2021/5/13 to 5/20). Association between their eating habits and the Nutrition Quotient for Korean Adolescents (NQ-A) were also explored. This study included a total of 604 students, among whom 441 students were identified as night eating consumers. Among all subjects, 30.5% consumed night eating 3~4 times a week, 27.3% consumed 1-2 times a week, and 27.0% did not consume any night eating at all. The high-night eating group had a higher score of total NQ-A than the non-night eating group for both male (p<0.05) and female (p<0.001) students. This was because male students in the high-night eating group reported significantly higher rates of daily dinner consumption compared to non-night eating group. Furthermore, both male (p<0.05) and female (p<0.001) students showed a significant increase in ‘Moderation’. ‘Diversity’ was also significantly increased in female studies (p<0.05) as subcategories of dietary habits according to night eating frequency. These findings highlight the need for practical research to develop nutritional guidelines for night eating that reflect preferences of students while providing adequate nutritional habits.

본 연구는 고등학생의 건강증진행위를 설명하기 위한 가설적 모형을 구축하고 검증하기 위해 시도되었다. 연구대상자는 경기도 소재의 고등학교에 재학중인 1∼3학년 학생 395명을 대상으로 구조화된 설문지를 이용하여 2017년 12월01일부터 12월22일까지 자료를 수집하였다. 본 연구의 외생변수는 가족기 능, 친구지지, 학교생활환경, 지역사회 사회자본이고 내생변수는 자기효능감, 자기조절능력과 건강증진행위 이다. 수집된 자료는 SPSS 21.0과 AMOS 22.0 프로그램을 이용하여 분석하였다. 연구결과, 최종 수정모형 은 권장수준을 만족하여 가설적 모형에 비해 적합도와 간명도가 향상된 것으로 나타났다: χ2/df=1.96, GFI=.90, AGFI=.88, CFI=.94, TLI=.93, RMSEA=.05, SRMR=.06. 가설적 모형에서 설정한 13개의 경로 중 4개는 기각되었고 9개의 경로는 통계적으로 유의하였다. 이들 경로에 포함된 변수는 가족기능(β=.57), 자기효능감(β=.29), 자기조절능력(β=.14), 지역사회 사회자본(β=.14), 친구지지(β=.13)로 설명력은 86%이었다. 따라서 역기능적 가정과 해당 가정의 청소년의 건강증진행위를 위한 사회적지지 체계를 구축 하고 학교를 포함한 지역사회 환경조성을 위한 프로그램 개발이 필요하다.

The present study investigated students’ preferences for the types of tasks used to assess English speaking performance. It further examined whether students’ task type preferences affected their perceptions of test effectiveness. One hundred eighty-two high school students responded to a self-report questionnaire. A series of frequency analysis and paired samples t-tests were used for the analysis. The results showed that students’ most preferred task types and their least preferred ones overlapped with each other, suggesting that the task types of English-speaking performance tests used in schools are limited. The four key reasons determining students’ task type preferences were identified, including task difficulty, emotional comfort, practical value, and interest. In addition, the results indicated that students’ task type preferences could affect their perceptions of task effectiveness. Overall, the results suggest the need for developing more varied task types for English-speaking performance tests as well as helping students become familiar with English speaking performance tasks. Pedagogical implications were discussed along with study limitations.

This study aimed to investigate the relationship between eating speed and nutritional status among Korean high-school students using Nutrition Quotient for Korean Adolescents (NQ-A). In this study, a questionnaire survey was conducted in 453 high-school students (227 boys and 226 girls) from September 2019 to October 2019 in Chungbuk area. Based on the self-reported speed of eating data, subjects were classified into a fast group (n=180), a medium group (n=184), and a slow group (n=89). NQ-A scores for each group were measured in each speed group. In the environment section, girls showed a significant difference in usage time of electronic devices, such as TVs and smartphones: the fast group spent significantly more time than the medium group (p=0.035). In the practice section, among boys, the slow group had significantly higher scores for washing hands before eating than the medium and the fast groups (p=0.022). This study suggested that eating speed of high school students is associated with health-related environment factor and practice factor of NQ-A, such as time spent on smart devices or washing hands before eating. The study results can provide baseline data for nutrition education on health management of high school students.

This study investigated how Korean high school students use English connectives in argumentative writing. The participants were 71 high school second year students. Analysis of data focused on three aspects of connective use: 1) the frequency and kinds of connectives used, 2) commonly used words in each category of connectives, and 3) frequently used positions of connectives. Considering the possible effect of topical knowledge and general English ability, the analysis included the comparison between two topic groups and between two language ability groups. The results showed there was a high similarity between different topic groups and ability groups in the use of connectives, but a significant difference was also found in some limited features. Based on the results, the study concludes that Korean high school students, regardless of the writing topic and language ability, share common features in the use of English connectives. Some suggestions are made for further research and writing instruction.

In the era of the 4th industrial revolution, creativity plays a pivotal role in the competitiveness of a country. The importance of creativity education therefore cannot be overemphasized. The purpose of this study is to examine the effects of discussion-based English reading and writing activities on Korean high school students' creativity, English writing, and self-assessed creative thinking. The participants were 45 high school students in Seoul, Korea. They were divided into two groups: the discussion-based English reading and writing group (n=24) and the traditional English instruction group (n=21). The experiment was administered during two semesters of the 2017 academic year. The major findings are as follows: First, the experimental group showed significant improvement on the creativity test, especially in the areas of fluency, flexibility, and original thinking. Second, the experimental group outperformed the control group on the writing test. Third, the experimental group showed positive changes in their self-assessed flexible thinking, convergent thinking, and intrinsic motivation. All of these indicate the beneficial effects of the discussion-based English reading and writing activities. Based on the results, some pedagogical suggestions were made for the effective integration of creativity education into the teaching of English as a foreign language.

The present study attempts to provide empirical and qualitative evidence to support the feasibility of rubric-referenced self-assessment to promote learning in a Korean high school EFL context. Over four rubric-referenced self-assessment lessons, with the help of a teacher’s instructions, students wrote a first draft and assessed it using a scoring rubric. Drawing on this self-assessment, they wrote a second draft, also followed by a self-assessment as well as a self-assessment diary. As quantitative data, the scores of the first draft of the first class were compared with those of the second draft of the fourth class. Survey questionnaires, interviews, self-assessment diaries, and essay self-assessments served as qualitative data. The findings are, first, rubric-referenced self-assessment showed positive effects on students’ writing quality. Second, students came to perceive the effectiveness of rubric-referenced self-assessment. Lastly, rubric-referenced self-assessment positively influenced students’ learning strategies and attitudes. These results imply that rubric-referenced self-assessment promotes learning in a Korean high school EFL context, leading students to become self-regulated learners that take responsibility for their own learning.

This study investigated the relative effects of input-based versus output-based activities on the learning of English unaccusative constructions. A total of 73 high school students were randomly assigned into two experimental groups and one control group. Of the two experimental groups, the input-based input enhancement group (IE group) experienced a reading passage with the learning targets visually enhanced. The output-based dictogloss group (DG group) performed the dictogloss task with the identical passage given to IE group. The control group (CG group) did not experience the learning targets at all. Results showed that IE group statistically significantly outperformed CG group both at the immediate and the delayed posttests, while there was no significant difference between IE group and DG group. In terms of the generalizability of the learned knowledge, however, it was DG group that outperformed CG group at the immediate posttest. Again, there was no difference between IE group and DG group. More detailed findings are provided, along with some implications for English classrooms in Korea.

This study was conducted to investigate the effects of the sentence-writing task on English vocabulary learning of Korean high school students. The effectiveness of the sentence-writing task can be explained based on the Involvement Load Hypothesis (Laufer & Hulstijn, 2001); yet, there has been no consistency in the results of the previous studies on this hypothesis. In the present study, the effects of the sentence-writing task on vocabulary learning were re-examined in comparison with the gap-filling task. In addition, considering that there have been no studies addressing the effects of autobiographical elaboration (relating the meaning of a certain word to one’s own experience) on memory, the effects of the autobiographical sentence-writing task were compared to those of the imaginary sentence-writing task. Forty high proficiency and 40 low proficiency learners were randomly assigned either of the sentence-writing or the gap-filling task. The results demonstrated that the sentence-writing task is more effective in vocabulary learning than the gap-filling task, regardless of the learners’ proficiency levels. However, no significant difference was found between the effects of the autobiographical sentence-writing task and the imaginary sentence-writing task. Based on the results, the pedagogical implications were discussed in the conclusion chapter.

This paper examined effects of three types of written corrective feedback (CF) on L2 learners’ grammatical accuracy in writing, focusing on the use of verb tense and articles. Within Ellis’ (2008) typology of CF, the present study focused on direct, indirect, and metalinguistic CF. The feedback was provided at each stage of writing, and the participants were to write three new pieces of writing. Changes in the accuracy of the grammatical targets were measured. Results indicated that despite the limitations of the small number of the participants, positive changes in the grammatical accuracy were found with metalinguistic CF for verb tense and with indirect CF for articles in new pieces of writing. In addition, unlike previous studies, a negative role of direct written feedback was observed in the present study.

This study investigated the effects of using comic strips and context on the vocabulary learning of Korean high school students. Ninety high school students participated in the study and they were divided into three groups: a control group and two experimental groups using comic strips and using context, respectively. In addition, questionnaires were used to investigate students’ attitudes toward English vocabulary learning. The results of the study revealed that there were statistically significant differences in productive vocabulary retention among three groups in terms of short-term memory. In particular, the experimental groups showed high short-term memory rate compared with the control group, which may mean that the use of comic strips and context in English vocabulary learning is effective in improving learners’ productive vocabulary retention. Also there was a statistically significant difference in productive vocabulary retention among three groups in terms of long-term memory. The experimental groups showed a high long-term memory rate compared with the control group. The results of the questionnaire revealed that the two experimental groups showed more positive attitudes towards English vocabulary learning. This may suggest that teaching vocabulary with comic strips and context could be effective for students in English classes, and it is very helpful to develop various activities using comic strips and context.

The purpose of the study was to investigate the causal relationships among factors affecting L2 reading achievement using a structural equation modeling (SEM) analysis. A total of 327 Korean EFL high school students completed a questionnaire on L2 reading motivation and strategies. The students’ L2 listening and reading comprehension abilities were measured by scores on the practice test for Scholastic Aptitude Test (PSAT) and self-assessed listening and reading proficiency. The study results showed that the students’ L2 reading efficacy, L2 reading strategy use, and L2 listening skills were significant predictors of their L2 reading achievement, while L2 reading motivation showed no significant relation with reading achievement. The nonsignificant path loading between reading motivation and reading achievement implies that reading motivation alone is not sufficient to promote students’ L2 reading proficiency. The final SEM model indicated a relatively strongest contribution of L2 listening ability over L2 reading efficacy and strategy use to L2 reading achievement. Pedagogical implications based on the findings are discussed.

This study investigates the effects of collocation task types on Korean high school students' collocation learning and learning attitudes. A total of 118 Korean high school students participated in the experiment, and they were divided into four groups: control group, receptive treatment group, productive treatment group and combination treatment group. In order to investigate the effects of collocation task types on students' English proficiency, each group of students was classified into a high proficiency group and a low proficiency group. The students took a pre-test before the experiment and a post-test after the experiment. After the post-test, the post-questionnaire survey was conducted to examine the students' learning attitudes. The results of the study were as follows: (1) The three types of collocation tasks were effective in learning receptive and productive collocations; (2) in the delayed retention test, it was revealed that the effect of the three types of collocation tasks on both receptive and productive collocation learning lasted; and (3) the result of post-questionnaire survey showed that learning collocation through collocation tasks had positive influence on most students in terms of raising their interest and increasing their self-confidence.
