This paper aims to discuss the effects of learning how to write English interrogative sentences. 122 students who participated in the study learned basic structural components of English questions and practiced writing questions by inversing the subject and the verb in a given declarative sentence. The participants were divided into two groups: Group 1 which was given a brief explanation of interrogative structures and practices, and Group 2 which was given the same explanation and practices in addition to an assignment for which they had to make one or two comprehension questions based on reading a passage. For the pre-tests and the post-tests, they took a TOEIC reading test with 40 questions and a structure test with 25 questions. The results of the tests show that both groups improved significantly in the two post-tests, benefiting from this learning method. However, the additional treatment for Group 2 did not seem to be highly effective. In the questionnaire survey, the participants think that the method of learning English questions has helped them better understand English grammar as well as interrogative structures. The participants were also divided into three different levels: high, intermediate, and low. The intermediate level group students benefited most from learning writing questions as the results of the post-test of the 25-questions test and the final exam of the course show.

The purpose of this study is to verify the mediating effect of interaction among learners in a Web Based Collaboration Learning (WBCL) environment. 254 Korean college students served as test subjects and during the 4 weeks of research period, they studied the Test of English for International Communication (TOEIC) in a web-based collaborative learning system. The interaction between learners was looked into by categorizing the concept into task oriented information sharing activities and relationship oriented communication activities and analyzing the causal relationship between the two activities. Learning performances were measured in individual level. The results are as follows. First, task oriented information sharing activities effect positively on relationship oriented information sharing activities. Second, the managerial characteristics of WBCL had a positive effect on interaction between learners but the systematic characteristics had partial influence on interaction between learners. Third, the interaction between learners completely interconnects the managerial characteristics of WBCL and learning performance but partially interconnects the systematic characteristic of WBCL and learning performance. In conclusion, this study implies that managerial and systematic characteristics of WBCL should be considered on the preferential basis for the WBCL to become successful and interactive activities such as information sharing and communication should be encouraged to be active from a small-size WBCL perspective.

This study was designed to identify students' perceptions and attitudes towards dictation practice in English listening classes and investigate the relationships among 5 factors with regard to dictation practice: participation, usefulness, interest, motivation, and confidence. For the study, the research was implemented for 15 weeks with 41 Korean university students. The subjects had dictation practice in their English listening classes on a regular basis for one semester. At the end of the semester, a questionnaire was used to find out students' perceptions and attitudes towards dictation practice. For the analysis of the subject's responses, first, a descriptive analysis was administered. After that, a correlation analysis was done to explore what the relations among 5 factors were. Results indicated that most students actively participated in the class, and they regarded dictation as a very useful practice in their listening classes. Also, the dictation practice motivated students not only for English listening but also for overall English studying. However, more than two third students showed low interest and confidence in the class. As for the correlations among 5 factors, there were very strong correlations between usefulness and motivation, usefulness and confidence, interest and motivation, interest and confidence, and confidence and motivation. Based on the results, some implications were presented and some guidelines for effective dictation practice were suggested.

Using mobile technology in educational and learning environments has attracted a lot of attention in recent years. In this mobile environment, mobile phones have been used to enhance the effectiveness of education in the field, which has been recognized through numerous experimental studies so far. The study was proposed and conducted to find out how much the use of mobile phones can have to improve the grammatical knowledge of EFL students. Introduction of 95 intermediate courses to Chungnam area The second grade students of 4-year college participated in this study. Everyone in the experimental and control groups was given the opportunity to review and recur to use the six grammar formats, including the current complete tense, simple past tense, direct and indirect question sentences, and comparative and superative-based methods. During the class discussion, the participants of the group record their voice on their cell phones, analyze the mistakes in the expressions recorded as a task after the class, and explain the results in the next session. However, in the class of the control group participants, this recording process is omitted. Participants benefited from mobile learning were much more positive in multidimensional grammar tests than those in control groups.

기계 독해란 주어진 문서를 이해하고 문서 내의 내용에 대한 질문에 답을 추론하는 연구 분야이며, 기계 독해 문제의 종류 중에는 여러 개의 선택지에서 질문에 대한 답을 선택하는 객관식 형태의 문제가 존재한다. 이러한 자연어 처리 문제를 해결하기 위해 기존 연구에서는 사전학습된 언어 모델을 미세조정하여 사용하는 방법이 널리 활용되고 있으나, 학습 데이터가 부족한 환경에서는 기존의 일반적인 미세조정 방법으로 모델의 성능을 높이는 것이 제한적이며 사전학습된 의미론적인 정보를 충분히 활용하지 못하여 성능 향상에 한계가 있다. 이에 본 연구에서는 기존의 일반적인 미세조정 방법에 템플릿을 적용한 템플릿 기반 미세조정 방법을 통해 사전학습된 의미론적인 정보를 더욱 활용할 수 있도록 한다. 객관식 형태의 기계 독해 문제 중 하나인 토익 문제에 대해 모델을 템플릿 기반 미세조정 방법으로 실험을 진행하여 템플릿이 모델 학습에 어떠한 영향을 주는지 확인하였다.

Relationships between students' perception of psychological distance with online professors and their academic learning achievement and their intention to continue online learning were examined. The courses selected for this study are two online courses: 1) 'English Grammar' and 2) 'TOEIC (Test of English for International Communication) Preparation' offered by a campus-based, medium-sized university. This study employed a mixed-methods approach by conducting a survey as well as one-on-one interviews with students. Students who feel psychologically distant with the online professors show significantly lower degree of perceived learning achievement, and higher tendency not to take online courses any more. All the three scales measuring the psychological distance -mutual awareness, connectedness, and availability- with professors turned out to be significantly related with students' perceived learning achievement. According to the result of the interview data analysis, the student interviewees unanimously said that the university should limit the number of online courses that students can register in a semester to one or two courses. Most students regard low interactivity of online learning as inevitable phenomenon. There is a statistically significant difference in perceived learning achievement between the online preferred group and the offline preferred group. Also, there is a significant difference in connectedness and availability and no significant difference in the degree of mutual awareness between the online and the offline preferred group.

The purpose of this study was to investigate (1) the aspect of the correlation among subcategories in English reading anxiety, (2) the aspect of the cause and effect relation. The reading anxiety was measured by a questionnaire. Then, the results were analyzed by SPSS program. The findings of this study were as follows: First, most of the sub-elements in reading anxiety in both groups correlate with one another even though the overall coefficient of correlation in high achievement group is rather higher. Second, it is also found that the lack of confidence for reading has negative influence on entire reading anxiety in both groups, which is followed by lengthy reading, evaluation and general anxieties in consecutive order. The implication of this study is that the teachers and students should be aware that the constituents of reading anxiety not only correlate with one another, but have great deal of relative influence on reading process. Therefore, teachers should organize a learning environment where learners can minimize the feeling of anxiety.

Data mining techniques enable us to generate useful information for decision support from the data sources which are generated and accumulated in the process of routine organizational management activities. College administration system is a typical example that produces a warehouse of student records as each and every student enters a college and undertakes the curricular and extracurricular activities. So far, these data have been utilized to a very limited student service purposes, such as issuance of transcripts, graduation evaluation, GPA calculation, etc. In this paper, we utilized Holland career search test results, TOEIC score, course work list and GPA score as the input for data mining, and we were able to generate knowledge and rules with regard to the college road map advisory service. Factor analysis and AHP(Analytic Hierarchy Process) were the primary techniques deployed in the data mining process. Since these data mining techniques are very powerful in processing and discovering useful knowledge and information from large scale student databases, we can expect a highly sophisticated student advisory knowledge and services which may not be obtained from the human student advice experts.

The purpose of this study is to understand students' use intentions of Web Based Collaborative Learning (WBCL) system. To meet this purpose, we developed a research model based on the Decomposed TPB. This model contains 5 influencing factors: Explicit social influence(EXSI) and Implicit social influence(IMSI), Perceived Usefulness (PU), Perceived easy of use(PEOU), Perceived Playfulness(PP). Data was collected 254 university students from two different institutions. Also, the analysis is conducted to do the hypothesis testing by using PLS 3.0. The result shows that influence factors except PEOU have a important and significant impact on user Behavior Intention(BI). Using WBCL system and learning tool, team leader(that is referent) and members can be a good interaction. For these same reasons, We found that especialy Explicit social influence(EXSI) and Implicit social influence(IMSI) are special influence factors in reference group.
