With technological advancements, Automated Writing Evaluation (AWE) has garnered increasing interest in L2 writing research, significantly enhancing our understanding of AWE tools’ practices and efficacy in L2 writing instruction. However, the relationships between feedback types (teacher vs. AWE) and different dimensions of engagement (cognitive and affective) remain largely underexplored. This study investigates the impact of feedback types on learners’ cognitive and affective engagement, as well as their L2 writing development. Seventy-two EFL learners participated as part of their regular English curriculum. Over twelve weeks, students received feedback on their essays from either a teacher or AWE programs. Progress in writing abilities was tracked through measurement tests, and engagement questionnaires were administered. Results indicated that both feedback types improved L2 writing abilities. However, teacher feedback proved more effective in promoting students’ cognitive and affective engagement compared to AWE feedback.

By adopting a usage-based approach to language acquisition, this study investigated the emergence and development of L2 constructional knowledge. A total of 19 English verb-argument constructions (VACs) and their associated verbs were extracted from a learner corpus and three verbal fluency tasks, each conducted in L1 and L2 English and L1 Korean. We compared verb usage in the target VACs across proficiency levels between the L1 and L2 groups and between data types for VAC productivity and verb-VAC associations. The results identified three stages through which Korean learners’ VAC knowledge develops in L2 English: emerging through the frequent use of a few general verbs, expanding the range of verbs associated with a VAC to include more specific and prototypical verb types, and then developing them into a creative constructional schema. Moreover, we determined similarities between L1 and L2 English VAC knowledge in higher L2 proficiency levels, as well as L1 Korean influences related to L1 typology and L1 collocational transfer.

The Cognition Hypothesis postulates that more cognitively complex tasks can trigger more accurate and complex language production, thereby advancing second language (L2) development. However, few studies have directly examined the relationship between task manipulations and L2 development. To address this gap, this article reviews, via an analytic approach, nine empirical studies that investigated the impact of task complexity on L2 development in the domain of morphosyntax. The studies are categorized into two groups based on if they include learner-learner interaction or a focus on form (FonF) treatment provided by an expert interlocutor. The results indicate that the findings of the studies, albeit partially mixed, tend to support the predictions of the Cognition Hypothesis. More importantly, a further analysis reveals seven key methodological issues that need to be considered in future research: target linguistic domains, different types of FonF, the complexity of the target structure, task types, outcome measures, the use of introspective methods, and the need of more empirical studies and replicable study designs.

Recently, the advancement of information and communication technology(ICT) is expanding the connectivity through Internet of Things(IoT), and the media of connection is also expanding from wire/cable transmission to broadband wireless communication, which has significantly improved mobility. This hyperconnectivity has become a key element of the fourth industrial revolution, whereas the supervisory control network of purification plants in korea is operated as a communication network separated from the outside, thereby lagging in terms of connectivity. This is considered the best way to ensure security, and thus there is hardly any consideration of establishing alternatives to operate an efficient and stable communication network. Moreover, security for management of a commercialized communication network and network management solution may be accompanied by immense costs, making it more difficult to make new attempts. Therefore, to improve the conditions for the current supervisory control network of purification plants, this study developed a industrial security L2 switch that supports modbus TCP(Transmission Control Protocol) communication and encryption function of the transmission section. As a result, the communication security performance improved significantly, and the cost for implementing the network management system using Historical Trend and information of HMI(Human Machine Interface) could be reduced by approximately KRW 200 million. The results of this study may be applied to systems for gas, electricity and social safety nets that are infrastructure communication networks that are similar to purification plants.

This study investigated the effects of negotiation in the process of providing written corrective feedback (WCF) by comparing three different patterns: non-negotiation, minimal negotiation, and extended negotiation. The data were collected from three intermediate academic English classes at a university in Korea. Each class was exposed to different degrees of negotiation while they received WCF for two target forms, the past verb forms and the English articles, in their written production (text re-construction tasks). Their accuracy improvement was measured by text-reconstruction writing tasks and error correction tests. The study found that the use of negotiation affected accuracy improvement of the target forms; however, its effectiveness varied depending on the target forms and measurements. For the past tense, negotiation, regardless of its amount, resulted in more accuracy improvement than non-negotiation in both text re-construction tasks and error correction tests. However, for the English articles, negotiation operated differently: extended negotiation significantly brought about more accuracy development in both measurements, but the difference between minimal negotiation and non-negotiation was only observed in the error correction test, not in the text re-construction task.

The role of oral corrective feedback (CF) in second language (L2) learning has been extensively investigated. However, little attention has been given to the relationship between different types of CF and explicit/implicit L2 knowledge. For this reason, the present study explored the effects of recasts and metalinguistic feedback on the development of explicit and implicit knowledge of the English articles. Sixty-three university students enrolled in intermediate Communication English classes participated, and they were assigned into a metalinguistic group, a recast group, and a control group. While the students engaged in meaning-based activities (i.e., retelling stories), the feedback groups received respective CF on the errors of English articles and the control group did not receive any feedback. Untimed grammatical judgement tests were employed to measure the students’ improvement of explicit knowledge and elicitation oral imitation tests were used to examine their gains of implicit knowledge. The study found that both recasts and metalinguistic feedback equally facilitated the development of explicit knowledge over time. However, they were not as effective as in the improvement of implicit knowledge, showing a short-term effect on the development.

This study examines whether revision mediates the effects of its preceding written corrective feedback (CF) in developing second language (L2) knowledge. For this purpose, effects of direct CF and three sub-types of metalinguistic CF with and without revision were compared in the quasi-experiment with 197 EFL university students. They formed 9 groups (i.e., 4 revision groups, 4 non-revision groups, and 1 control group) and completed 4 dictogloss writings. Written CF and revision were implemented after the first two writings. English articles were the target structure for the written CF. The first, third and fourth writings were measured for the accuracy of article use as the pre-test, the immediate post-test and the delayed post-test, respectively. The results reveal that revision did not affect the efficacy of direct CF while it enhanced that of metalinguistic CF to varying degrees with its subtypes. These findings indicate that, if revision is conducted following written CF with particular metalinguistic information, it may facilitate learning new L2 knowledge beyond manifesting existing L2 knowledge.

This study investigated the effect of implementing the literature circle activities which integrated journal writing practices on college L2 learners’ writing development and their perceptions on integrating literature circle activity in an academic writing classroom. Students’ writing development was measured focusing on complexity, accuracy, and fluency (CAF) through the paired t-test and writing proficiency test In both computer-based analysis and manual analysis, the results showed that there were statistically significant improvements in the participants’ lexical diversity and variation, in such measures as the number of diverse words, type/token ratio, and lexical variation. In the syntactic complexity, in the use of complex nominal phrases per T-unit, complex nominal clauses per clause, coordinate phrases per T-unit and clause per T-unit, statistically significant results were found. All three measures of accuracy showed statistically significant improvement. The participants’ fluency were also found to be improved with statistically significant results. Regarding participants’ perceptions on the journal writing practices and discussion for literature circle activity, over 75% of students positively responded in a questionnaire survey. The results suggest that integration of literature reading and writing can positively influence on L2 learners’ writing development.

Although reading is part and parcel for the development of L2 literacy skills, such as in reading and writing, the skill has been practiced more often for grammar instruction and literal translation in EFL contexts. While realizing there is less focus on the development of L2 skills through extensive reading (ER) in EFL university contexts,the purpose of the present study was to explore the outcome of an in-class ER approach in English university classrooms. With 249 students, the study reports on the implementation of a university level ER class and the outcome for L2 development via the measures of L2 reading speed, L2 speed reading comprehension, and L2 lexical writing ability. Results indicated positive outcomes for the development of students’ L2reading ability, productive retrieval of academic words and lexical variety. The outcome of the ER program validates the effort and time expended on such programs when graded readers are utilized at matching student Lexile levels.

This present study concerned whether prompts and recasts that occur during interaction could play a role in L2 development. Adopting an untimed grammatical judgment test and an elicited oral imitation test to measure explicit and implicit knowledge, this study examined the relative effects of prompts and recasts on L2 development of past tense forms. The participants were pre-intermediate learners enrolled in English as a foreign language (EFL) classes at a university in Korea. The learners were assigned to two prompt groups, a recast group, and a control group. The analysis of the untimed grammaticality judgment test revealed that the participants promoted their explicit knowledge of the past tense forms of regular and irregular verbs when prompts were provided. The analysis also showed that the learners who received recasts improved their test scores but only in irregular past tense forms. No significant group difference was found among the treatment groups and the control group in the results of the elicited oral imitation test used to measure implicit knowledge of the target forms. These results indicated that prompts were beneficial for short-term L2 grammatical learning of EFL learners of pre-intermediate level. The implications and limitations are discussed in terms of the role of prompts in driving L2 development.

This study investigates the implementation of a new EFL course, English Practice. This is designed to enhance English reading and writing skills, and increase literary experiences among university students. For this study, literature for young adults and e-mail writing were introduced to change teaching/learning conventions in an EFL setting. The research framework was practitioner research. Data collection consisted of a survey, students’ writing in the classroom, and the instructor’s field notes and journal. Data were analyzed to address the following research question: What happens when university EFL students read and write English for real purposes? Data analysis revealed that: 1) the students viewed literature and e-mail writing as a new experience of language learning, 2) the students showed changes in their learning, and 3) the students’ experiences with the literature went beyond language learning. The author concludes that the unique course program provided students with new ways of developing understanding English as a foreign language and provided opportunities to express individual experiences of the texts they read.

교실 내 다문화 배경 아동 학습자가 늘어가고 있으나 이들의 KSL 학습을 지원할 예비 초 등 교사에 대한 이론적 교육과 훈련이 부족한 실정이다. 이에 교육대학교에 재학 중인 두 명의 학생이 협업을 통해 다문화 교실 환경을 겨냥한 이중 언어 교육 시행 방안을 강구하 도록 하였다. 참여자들은 CLIL 기법을 접목하여 한국어와 영어 교과를 내용교과인 사회와 결합한 통합 교과 모형을 개발하였다. 이 과정에서 참여자들은 의견 상충과 정체를 겪기도 하였으나 입장을 재조정하고 문제 해결 방법을 모색하여 공동의 결과물을 도출해낼 수 있 었다. 다문화교육에 대한 인식의 측면에서는 예비 교사로서 개선 의지와 문제의식을 가지 고 있으나 현실적 어려움을 극복하는 새로운 도전에는 소극적인 태도를 드러내었다. 또한 이론적 배경과 실제적 경험의 부족으로 다문화 배경 학습자에 대한 편향된 시각을 보이기 도 하였다. 이와 같은 결과는 공교육 교실 환경에서 교육자가 언어․문화적 다양성을 지닌 아이들이 상호 발전하는 제2언어 학습을 이끌어내기 위해 개인의 인식 확장과 노력뿐만 아 니라 공공의 제도적 지원이 뒷받침되어야 한다는 함의를 지닌다.
