The purpose of this study is to research the concepts of reading ability and debate ability, and the components of both abilities and to make the performance assessment's standards to apply them to the classroom for reading debate in the school libraries. For doing this, I studied the necessity of reading debate, assessment, and the components of reading/debate abilities. The components of the reading and debate abilities were derived from the theoretical researches and the performance assessment's standards for the reading debate were proposed in the viewpoint of the teacher librarians and classroom teachers in the school libraries in order that the teacher librarians and teachers could apply them to the reading debate classes and assess the performance achievement of the students.

Mathematical discussion has been highlighted so that what students do actually guides their learning of mathematics and mathematical practice. However, the work of leading mathematical discussions has not yet been specified in such a way that it can be adequately studied and taught to teachers. This study analyzes a teacher's lessons that show full engagement in leading discussions, and examines the work of leading mathematical discussions in elementary classrooms. It identifies and illustrates the central tasks of leading mathematical discussions with single case questions with five steps. This article argues several key issues in leading mathematical discussions: helping students engage in struggling with important mathematical ideas, treating mathematical connections in an explicit and public way to have coherent and structured discussions, and parsing the work of teaching at a grain size that is usable in educating teachers.

The purpose of this study was to construct an issue-centered discussion instructional model for Home Economics and to determine its effect on middle school students' critical thinking. The research questions were posed as below. 1) The object and content of home economics in the 7th national middle school curricula are analyzed to sort out possible issues. 2) An issue-centered discussion instructional model is constructed to be applicable to middle school home economics class. and a lesson plan is prepared. 3) The effect of the issue-centered discussion instructional model developed in this study on student critical thinking faculty is examined. The findings of this study were as follows : First. seven criteria were selected to determine what types of issues were applicable to home economics lesson. Based on the selected criteria. 41 themes of issues were extracted from the 7th middle school textbooks. and their content validity was verified. Second, an issue-centered discussion instructional model was designed to deal with four themes in eight sessions in the procedure of problem raising, confirming, term defining. tentative alternative selecting, data gathering. discussing/critical approaching. and selecting/concluding. Third, two different third-year classes of K middle school in the city of Busan that consisted of 75 students were respectively selected as an experimental group and a control group, and the experiment was conducted in eight sessions for five weeks to see whether the teaching plan brought any changes to the critical mind of the students. The experimental group exposed to the issue-centered discussion lesson made a significant progress in critical thinking faculty(P＜.05). In particular. that instruction gave a favorable impact on demonstration evaluating(P＜.05). one of the critical thinking subfactors. When the students were asked to assess the issue-centered discussion lesson. most of them viewed it favorably. In the future, more research efforts should be dedicated to enhancing the practical applicability of issue-centered discussion instruction in home economics education. developing good evaluation tools about critical thinking faculty and finding out how discussion instruction could be conducted more efficiently.

In this study, messages from on-line discussions of 28 preservice teachers were analyzed based on social constructivist learning theory. After preliminary discussion session for a week, small group discussions were conducted every single week with different topics during 4 weeks. One transcript with most frequent messages in each topic was selected, and a total of 72 messages were analyzed. Discussion topics were the issues related to the nature of science. The Interaction Analysis Model for Examing Social Construction of Knowledge in Computer Conferencing was used for the analysis. Analysis of the messages indicated that 'sharing information' was the most frequent, and that 'discovering/exploring dissonance' and 'negotiation of meaning/co-construction of knowledge' were the nex. However, messages of 'testing and modification of proposed synthesis' and 'testing and application of newly constructed meaning' were found to be rare. This result indicated that students' interaction through on-line discussion did not reach to the social construction of knowledge.

In this study, a concept learning strategy emphasizing social consensus during discussion (SCS) was developed. The instructional effects of this strategy were compared with those of cognitive conflict strategy (CCS) and traditional instruction in the aspects of students' achievement, conceptions, communication apprehension, perceptions of science learning environment, and perceptions of small group discussion. There were no significant differences in the scores of an achievement test. For the students of low communication competency, however, the scores of the CCS group were significantly higher than those of the traditional group. The adjusted mean of the SCS group was higher than those of the other groups in a conceptions test. The social consensus strategy was also found to be more effective in learning concept for those who were more competent in communicating. No significant differences were found in the communication apprehension. The scores of three groups did not differ significantly in the subcategories of 'personal relevance' and 'students' negotiation' of the test of the perceptions of science learning environment. However, the students in the SCS group scored higher in 'participation'. The students in the SCS group perceived small group discussions more positively.

The purpose of study is to examine the effects of the reading discussion-oriented career exploration program for elementary school students on career development and achievement motivation. To achieve this purpose, three fifth grade classes were assigned to an experimental group, comparative group A and comparative group B. Reading discussion-oriented exploration program for the experimental group was conducted for five weeks in ten sessions, the same period of time for comparative group A was given for conducting a career education program and subject studying was conducted on comparative group B. The results of this study, the experimental group applied to the reading discussion-oriented career exploration programs showed a significant increase in their career development compared with the subject studying group. But they did not show a significant increase compared with the career education group. Second, experimental group applied to the reading discussion-oriented career exploration programs showed significant increase their achievement motivation compared with the subject studying group and career education group.

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).

레지오 접근법을 토대로 한 구성주의적 지리교육이 현실적 적실성을 갖기 위해서는, 첫째, 도식적 언어를 통한 상징적 표상을 지식 구성의 결과가 아닌 과정적 도구로, 또는 토론의 매개체로 전환하여야 한다. 둘째, 주제(선도) 개념을 중심으로 연계성과 위계성을 가진 개념을 조직하고, 이를 토대로 여러 차시의 내용을 연계하여 수업해야한다. 섯째, 개인적 구성보다 사회적 구성이 보다 고차적이고 심층적인 지식 구성을 가능케 한다. 따라서 구성주의 수업은 협동적.토론적인 모습일 때가 바람직하다. 넷째, 수업의 방향성과 학습의 목적성을 위해 안내자, 조력자로서 교사의 역할을 다하여야 한다. 이때 안내는 학습자 스스로 자신의 학습 목적과 방향을 판단하는 매개체로서, 그리고 사고력을 증진시키는 디딤돌로써의 안내이어야 한다. 다섯째. 선행학습에서의 구성과정과 구성맥락을 재 상기시키고, 이를 통해 구서의 지속성과 심층성을 강화하는 나선형적 구성의 절차를 반드시 밟도록 해야 한다.

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.
