This study was conducted to explore the effect of the type of dashboard on online group discussion activities based on learning analysis. The experimental research was conducted among 51 learners from a university by dividing them into 2 groups. Group A provided participation and interaction dashboard, and group B provided the discussion topics and message type dashboard. First, pre-tests were conducted on attitudes toward computer writing and the level of motivation that could affect online discussion activities. Then the students participated three different topics of online group discussions. The participation and interaction data were automatically collected through the dashboard, and learning outcome data were collected through post-tests. The results showed level of participation in Group B (M=47.56, SD=2.37) that provided discussion topics and message type dashboard was significantly higher than the level of participation in Group A (M=38.13, SD=2.21) that provided participation and interaction dashboard. On the other hand, there were no differences in the level of interaction and learning outcomes. In future studies, we suggest that the dashboard effects based on the learners' characteristics should be carried out because the learners' characteristics may affect the use of the dashboard.

In this study, we explored the students' perceptions on the online discussion system for physics investigation as the physics education program. With these, we explored the characteristics of online discussion system. For these, the questions and interviews were executed in order to get informations about user-friendly characteristics of on-line discussion learning system of physics investigation, asynchronicity of on-line investigation discussion, on-line investigation discussion related to writing, visual cues and physical presence of on-line investigation discussion and preference of on-line investigation discussion. The students represented that there were two advantages in the online investigation discussion. One is that they could participate in the on-line investigation discussion without the restriction of time and space, and the other is that they could enter into a dispute with sufficient consideration because of the asynchronicity characteristic of online investigation discussion. Although the online educational activity is mainly achieved by independent work on the part of students, the role of teacher and parents is more important than the technical part of online educational system for the active participation.

CMC(Computer-Mediated Communication) 기술을 활용한 웹 기반의 토론/토의 학습이 최근 학교 현장에서 많은 주목을 받고 있다. 그 중 위키(Wiki)는 공동 주제에 대한 참여자들의 창의적 발상과 비판적 사고력을 신장할 수 있는 새로운 형태의 비동기식 토의 방식으로 기존의 게시판 형태와 비교할 때 많은 장점을 발견 할 수 있다. 본 연구에서는 초등학교 고학년 학생을 대상으로 토론 학습을 하기 위한 위키 시스템 기반의 토론학습 모델을 개발하고, 비판적 사고력의 신장에 미치는 영향을 조사한다.

기존 원격교육 시스템들은 주로 UNIX 기반이며 원격학습을 위한 모든 기능을 서버에서 처리하게 하였다. 따라서 대용량의 시스템이 필요하였고, 여러 강좌를 동시에 실시간으로 강의하는데는 여러가지 제한이 있었다. 본 연구에서 제안한 원격학습 시스템은 사양이 높아진 클라이언트 PC를 최대한 이용하여 서버 시스템의 크기를 줄였다. 원격강의를 할 때 강의의 개설은 메인 서버에서 이루어지게 하고, 실제 강의는 강좌를 개설한 교수 PC로 서버 기능을 전환하여 실시간 강의를 진행할 수 있도록 하였다. 이러한 방법은 서버에 집중되는 부하를 줄이고 실시간으로 동시에 여러 과목의 강의나 다양한 원격토론 학습이 가능하다. 또한, 원활한 강의 및 토론을 위해서 클라이언트 프로그램에 강의에 필요한 기능들을 최대한 포함시켜서 네트워크간의 데이터 이동을 최소화하였다.

In the conventional distance education systems, all functions for the distance education were processed by a server. Therefore, the system of high capacity was required and there were various restrictions to provide many classes in real-time simultaneously. The group-based distance education system proposed in this study reduces a load of the main server by distributing its functions to client PCs. In the group-based education system, the establishment of lecture or discussion rooms is executed by main server, but on the other hand, the functions of the conventional server are executed by a lecturer's PC or a discussion administrator's PC The test results of the system implemented in this study show that a lecturer's PC can afford to provide fifty trainees a lecture, though they depend on the specification of systems. Therefore, the proposed system in this study can afford to simultaneously provide with the various distance discussions and lectures by reducing a load concentrated to the server.

This research examines how e-PBL system affects 'self-directed learning ability' by applying it to "Science Cyber Conference" participants for 16 weeks. Participants' perception of PBL class process was also looked. After applying PBL program, participants' 'self-directed learning ability' has effectively changed statistically(p<.05). Especially, it showed significant change in 6 areas of 'self-directed learning ability' out of 7. Participants also showed positive response to PBL program (p<.05).

Until now, there are many technologies to improve studying ability using e-learning system. In most of e-learning system, learners are studying through the lecture materials and studying problems. The studying ability and intention, however, can be improved through the shared materials and discussion. In this case, learning materials are shared by the learners' discussion and shared materials through the board Internet and MSN. Such data was not classified by learners; it was not easy for the learners to search related valuable information. Therefore, it was not helping to learning. The technologies of most text mining extract summary data from the collection of document or classify into similar document from the complex document. In this paper, we implemented e-learning system for learners to improve learning abilities and especially, applied text mining technology to classify learning material for helping learners.

In this paper, we investigate the effects of group composition according to the personality type of learner on the content of discussion in web-based synchronous online discussion. The experiment for this study was conducted with high school students. First, we conducted the MBTI(Myers Briggs Type Indicator) test and based upon the result, we classified learners into 3 groups; introverts group, extroverts group, and introverts/extroverts mixed group. After the online discussion, the content of discussion were analyzed by the units of meaning, based on the four dimensions which were proposed in the 'content analysis model' by Henri(l992). Among four dimensions, 'social' and 'interactive' dimension belonged to category of inter-dependence, and 'cognitive' and 'metacognitive' dimension belonged to category of subject-relevance. The introverts/extroverts mixed group, which was heterogeneously composed, had the most positive effects on the total numbers of the units of meaning, the inter-dependence, and the subject-relevance of the contents of discussion.
