The number of studies on data-driven learning (DDL) has increased in recent years, and DDL's overall effectiveness as an L2 (second language) teaching methodology has been reported to be high. However, the degree of its effectiveness in grammar instruction, particularly for the goal of correcting errors in L2 writing, is still unclear. To provide guidelines for focused grammar instruction with DDL in the Japanese classroom setting, we aimed to identify the typical grammatical errors made by Japanese learners in the Cambridge Learner Corpus First Certificate in English (CLC FCE) dataset. The results revealed that three error types (nouns, articles, and prepositions) should be addressed in DDL grammar instruction for Japanese English as a foreign language (EFL) learners. In light of the findings, pedagogical implications and suggestions for future DDL research and practice are discussed.

Flexible tactile sensors can provide valuable feedback to intelligent robots about the environment. This is especially important when the robots, e.g., service robots, are sharing the workspace with human. This paper presents a flexible tactile sensor that was manufactured by direct writing technique, which is one of 3D printing method with multi-walled carbon nano-tubes. The signal processing system consists of two parts: analog circuits to amplify and filter the sensor output and digital signal processing algorithms to reduce undesired noise. Finally, experimental setup is implemented and evaluated to identify the characteristics of the flexible tactile sensor system. This paper showed that this type of sensors can detect the initiation and termination of contacts with appropriate signal processing.

성공적인 외국어 학습을 위해 필요한 요소 중 하나로 자기효능감이 주목받아 왔지만, 이와 관련된 연구 중 다수는 중등학교 학생들을 대상으로 수행된 연구들이다. 본 연구는 영어 독해와 작문 중심의 교양영어프로그램이 대학 신입생들의 자기효능감에 미치는 영향을 살펴보았다. 자료 수집을 위하여 교양영어프로그램을 수강하는 중급반 학생을 대상으로 사전-사후 설문을 실시하였고, 해당 학생들을 지도하는 교수자들을 대상으로 영작 지도 유형을 파악하기 위한 인터뷰도 실시하였다. 학생들의 자기효능감의 사전-사후 차이를 살펴보기 위하여, 대응표본 t-test로 분석하였으며, 일원분산분석으로 교수자의 지도 유형에 따른 차이가 있는지를 통계적으로 확인하였다. 그 결과, 독해·작문 중심의 교양영어프로그램이 중급반에서 영어를 학습하는 학생들의 자기효능감에 긍정적인 영향을 미쳤고, 교수자의 영작과제 부여 횟수와 운영방식에 따른 차이가 확인되었다. 본 연구의 결과를 토대로, 신입생을 대상으로 하는 교양영어 수업에서 학습자들의 성공적인 학습 경험을 높일 수 있는 다양한 유형의 과제 개발과 효과적인 교수자의 피드백 방식 등에 대한 후속 연구가 필요하며, 이는 학습자의 자기효능감을 높이는 데에 있어서 보다 효과적인 교양영어 수업 모델 개발로 이어질 것이다.

This study investigated whether writing weekly listening logs could influence college English learners' metacognitive awareness and listening proficiency. In addition, the Metacognitive Awareness Listening Questionnaire (MALQ) was applied to examine the learners' knowledge of their listening process. It is process-oriented research conducted by analyzing the MALQ and students' listening logs as to how their metacognitive awareness and listening proficiency have changed during the semester. Eighty-nine students who took an English listening practice course at a university participated in this study. The research findings are as follows. First, it turned out that there was a significant relationship between EFL university students' listening comprehension and some subscales of metacognitive awareness. Second, the students had an opportunity to reflect on learning through regular listening activities, and weekly listening logs, which included important information about listening process and practice. Third, as the students' listening proficiency increased at the end of the semester, it was found that introducing listening logs along with classroom lessons helped the students improve their listening ability. Finally, the high proficiency group students used multiple strategies simultaneously, regardless of the type of listening strategies, while the low proficiency group students used one or two limited listening strategies. However, the low proficiency group students may have had trouble expressing their ideas in English or recognizing the listening strategies they used, not because they did not use a lot of listening strategies. Therefore, teachers should regularly check if students are following their instructions and help them use appropriate strategies for better understanding.

본 연구의 목적은 기계번역을 활용한 대학교 영어쓰기 수업에서 한-영 기계번역 결과물에 나타난 형태적 및 구문적 오류 유형과 그에 대한 원인을 분석하기 위한 것이다. 한국의 EFL 대학생 7명이 연구에 참여하였으며, 그들은 한 학기동안 총 3회의 영어쓰기 과제를 수행하였다. 본 연구에서는 학생들이 제출한 영어쓰기 결과물 중 기계번역 결과물에 나타난 형태적 및 구문적 오류의 유형을 분석하였으며, 우리말 초고와 비교 분석을 통하여 그 원인을 찾아보고자 하였다. 분석결과, 기계번역 결과물에서 가장 많이 발생한 오류는 문장구조와 표기법 관련 오류였으며, 기계번역 결과물에서 발생한 대부분의 오류는 한국어 원문의 오류로 인하여 발생한 것으로 파악되었다.

본 연구에서는 영어를 모국어로 사용하지 않는 사람들에 대한 영어 관사 오류에 관한 연구로서, 우리나라와 같은 관사 체계가 없는 상황의 영어학습자들에게는 제2 언어(L2)인 영어 관사 체계를 습득하는 데에는 상당한 시간뿐 만 아니라 수많은 시행착오와 오류를 겪게 되어 영어학습자들은 관사를 정확하게 사용하는데 더욱 어려움을 겪게 된다. 그러나 영어 관사 체계 습득에 있어 학습자가 초보에서 고급 단계에 이르는 동안 겪게 되는 수많은 오류와 실수가 무수히 반복하는 것처럼 보이지만, 사실 학습자는 자기 나름대로 외국어에 대한 언어 체계를 구축하는 과정이라 한다. 학습자의 발화에서 발생하는 관사 오류를 분석함으로써 어떤 오류가 얼마나 빈번하게 발생하게 되는지 또한 그러한 오류가 단순히 모국어의 영향에서 비롯된 것인지 아니면 모국어와 영어 사이에 나타나는 전이 현상 때문인지에 관한 연구 필요성이 제기되고 있다. 연구에 참여한 학습자들의 영작문을 분석한 결과, 영어학습자들은 특히 정관사(the)와 부정관사(a/an)의 사용에서 많은 오류를 보이는 것으로 나타나고 있다. 이러한 분석 결과 통해서 영어학습자들을 대상으로 영어 글쓰기를 지도할 때는 무관사(zero) 보다는 정관사(the)나 부정관사(a/an)에 대한 교육에 더욱 초점을 맞추어진 지도가 매우 필요하다.

This study investigates the effects of written vocabulary exercises on lexical knowledge. Korean university students learning English as a foreign language were randomly assigned to one of four conditions-Condition 1 (having students match word form with word meaning), Condition 2 (having students fill in the blank provided with a list of words), Condition 3 (having students write sentences with the target words), Condition 4 (having students do three practices with the same vocabulary exercise as the condition 1). Each type of exercises in Condition 1, 2, and 3 was designed to classify a different level of mental processing except Condition 4 with multiple encounters of the target words. Learners' vocabulary knowledge of this study was obtained using a format adopted from the Vocabulary Knowledge Scale (VKS) immediately and two weeks later. The findings indicated that: (1) Condition 4 having students do three matching vocabulary exercises was as effective as the condition 3 (one writing exercise) on the immediate learning of word; (2) although there was no significant difference of the effect of vocabulary exercises between Condition 3 and 4, Condition 4 asking students to do three matching vocabulary exercises was the most effective way of vocabulary retention after two weeks.

The purpose of this research is to investigate the types of semantic errors made by MT in translating EFL college students' original drafts written in Korean into English. Specifically, this study attempts to find out 1) what types of semantic errors are most frequently committed by MT? and 2) how students feel about the quality of the MT-produced output? The findings from this study indicated that MT produced the errors related to accuracy (47%) the most, followed by the errors related to fluency and ambiguity (14.6% respectively). Students were well aware of the errors with accuracy and fluency but had limited ability to check the errors with ambiguity. Based on the findings, this study suggests pedagogical implications which can be implemented in L2 writing classrooms.

To compare data on the speech act of requests from two different methods, a study was conducted in which both native and non-native speakers of English participated as subjects, and data were collected by means of actual e-mail writing and DCT (discourse completion test). The analysis of requests from the two different data-gathering methods showed that despite some similarities, considerable differences existed between e-mail and DCT requests in several important aspects of requests such as amount of talk, directness level, downgraders and supportive moves which play an important role in making a given request sound less imposing and more polite. Also it was shown that requests of non-native speakers differed considerably from requests of native speakers in terms of the four aspects of requests across type of data-gathering methods. Based on the findings, some suggestions were made for both further research and L2 classrooms.

The aim of this study is to clarify the process of the sound changes of Japanese consonants (Dakuons) in the analysis of the transcriptions of Korean Source-Materials (i.e. Japanese textbooks for Korean and the records of travel in Japan) written in the 15-l8th centuries with the Korean writing system. Especially these records of travel in Japan are meaningful in that the process of change of Dakuon is shown in detail. The results are as follows. 1) In the 15th century, all Dakuons /g d z b/ had nasality. 2) The nasality of /z/ and /b/ disappeared in the 16th century. 3) The nasality of /d/ disappeared in the late 17th century.
