Edward de Bono's six thinking hats is effective to increase the excellence of the thinking and cultivate divergent thinking. In particular, this method is effective in finding a reasonable solution through analyzing issue from a variety of perspective. In this paper, we developed the system for an effective debate learning that student's own ideas based on six thinking hats are shared and expressed in speech and images through Android devices sensors. We analyzed the tools and guidelines by making design structural model for system design. The developed system was evaluated by the teacher through demonstration and practice and we analyzed through evaluation results the effectiveness and the improvement of the system. The evaluation results were analysed that the developed system is more effective improve motivation and debate ability than web based debate learning system.

Through WWW, one of Internet services, network infrastructure is grown explosively and web-based technologies have been developed tremendously. That technologies have had a potent influence on wide-area of society, so did educational area. Meanwhile, discussion is emphasized at school education because of its great advantages at a constructivist perspective and the part of performance assessment. But, there are many differences between web-based discuss-learning instruction and face to face discussion, because the former is based on interaction through the media especially networks. Consequently, in this paper, we look into about the consideration factors of the web-based discuss-learning instruction, and also study about the support system development factors and methods.

사이버커뮤니티의 발전상은 까페, 싸이, 블로그, 휴대폰 등의 형태로 개체화와 나열형 정보에 주력되어, 정보홍수로 인한 역설적 정보빈곤의 부작용 또한 커지고 있다. 이에 본 논문에서는 나열형 정보의 단점을 극복할 수 있는 공유형 정보의 구현방안으로서, '의미소개체화 기반 게임형토론시스템'을 제안한다. 기존에 나열형 정보의 대안이자 웹 2.0의 모델로 주목받아온 위키(wiki)방식의 원론적 공유에서 나아가, 구성개체 간 상호평가가 수치로 교환되고 그에 따른 가중치가 활용되는 방안이다. 이는 시맨틱 웹과 웹2.0의 통합적 논의이며, 인터넷의 자연스런 발전방향이다. 이 시스템이 구현된 인터넷(Internet)을 포럼넷(Forumnet)이라 부를 수 있다. 포럼넷은 현실적, 기술적으로 개인기반평가에서 개체기반평가로 구현되어갈 것이다.

This study analyzed the information-seeking behavior of preservice science teachers by observing the process of seeking information needed in a Socioscientific issues (SSI) debate class. Twenty-four fourth-year preservice science teachers participated in the study, and the SSI debate was conducted on the topic of biofuels. The results of the study revealed that preservice teachers go through the process of 'Searching', 'Reviewing', 'Interpreting', and 'Evaluating and Reorganizing' stages when seeking information. The searching stage is divided into identifying topics, role division, and standard setting for a search. The reviewing stage is divided into reviewing sources and reviewing contents. The interpreting stage is divided into interpreting an information and interpreting information from an integrating aspect. In addition, the evaluating and reorganizing stage is divided into evaluating information and reorganizing information. It was found that preservice teachers have difficulty reviewing information and interpreting multiple sources of information in an integrated aspect. Also, it was found that evaluating information activity among preservice teachers' information-seeking behavior affects the level of argumentation in discussions.

Considering the expansion of gifted education and the quantitative increase the Gifted Science Academy, it is important to seek the appropriate methods of mathematics teaching for gifted high school students. In particular, to reflect current trends in mathematics education that the mathematical creativity is being presented as an important educational goal, Now is the time we need student-centered discussion model for regular mathematics classes, not teacher-centered instruction in the way of knowledge transfer. In this study, class model of preparation-based discussion was designed and applied to the regular mathematics classes for the Science Academy. Students participating in this research had a lot of pressure in preparation activities for discussion, but they said that the discussion compared to traditional lecture was mathematically meaningful experience. These findings suggest the implication that class model of preparation-based discussion can be meaningfully applied to the regular mathematics class.

In this study, interaction patterns in peer small-group discussions with cognitive conflict strategy (CCS) and those with social consensus strategy (SCS) were compared. Verbal interactions of four small groups (16 students) in learning science concepts were analyzed at the levels of turns, interaction units, and episodes. The frequencies of total turns and knowledge construction turns per discussion for the SCS group were higher than those for the CCS group. Comparing and evaluating hypotheses and discussion worksheets provided were especially effective in increasing metacognitive utterances of the SCS group students. The frequencies of 'most students participating mode', 'elaborative interaction mode', and 'exploratory episode' for the SCS group were higher than those for the CCS group. These suggested that more students in the SCS group participated in small-group discussions and their discussions were more interactive and elaborative. The interactions and episodes of the SCS group were also superior in quality to those of the CCS group.

Assessment in the school should be done consistently in accordance with the national curriculum. This study analyzed the process that preservice teachers developed the question items. The preservice teachers already equipped with the knowledge about the curriculum, didn't reflect it to items at first. However, in the review and modification process with colleague discussions, they get the curriculum coherence faithfully. And the item completeness gets higher such as to conform to the item intent, to help the students easily understand the item and to have the consistency between items.

This paper introduces two concepts, specialization and representation, to evaluate activities of standing committees in Korean Assembly. Previous studies have criticized the committees based on frequent change of committee membership. After analyzing the empirical data of Finance and Economy Committee, it turns out that different from the previous arguments, the committee reaches the high level of activities in the perspective of specialization and representation. Changing of committee membership, after considering direction of the change and period of leaving the committee, is less happened than they are supposed. If voting by proxy or absentee voting were allowed, the frequency of the changing membership would be decreased. Study on Finance and Economy committee reveals that the extent of participation of the committee members is similar to the that of the floor meeting and that the number of participants and hours for each meeting display the characteristics of deliberative democracy of committee. Unanimous decisions outnumber majority ones. Therefore, this paper insists that standing committees in Korean Assembly works much better than what they have been criticized
