이 논문은 검사의 평가와 동등화에 관한 기본적 이론을 일목요연하게 소개하고 있다. 전반적으로 통계적 개념이 교육평가 분야에서 어떤 의미로 해석되고 있는가를 알기쉽게 전달해주고 있으며, 적절한 참고문헌과 패키지 프로그램이 소개되어 있어 통계인들이 이 분야에 접근하는 데에 많은 도움이 되리가 생각한다. 성태제 교수의 노고에 감사드리며, 이 분야의 문외한으로서 갖게도니 몇가지 의문사항으로 토론에 대신하고자 한다.

The purpose of this study is to examine the effects of small group discussion on elementary students' science writing. In this study, four 6th grade students were chosen from an elementary school in Seoul. Students were involved in eight science writing classes and the contents of a small group discussion and interactions were recorded and observed. Students' science works were collected and analysed based on three domains: scientific thinking, logic and originality. The result of this study showed that the contents of a small group discussion greatly affected the scientific thinking domain. A low-achieving student received lots of help from a high-achieving student. It was easy to improve in the logic domain through the science writing classes. Average students got good grades in an originality domain when the subject was related to their real life. A small group discussion would have an effect on science writing ability positively if the students acquired proper guidance on the procedure and manner of discussion. The science writing lesson would be more effective if the learning group was organized homogeneously in the aspects of intelligence achievement and interpersonal relationships.

The purpose of this study is the investigation and evaluation of participants' awareness in the Book debate club which is managed by library of C University in Gwangju. For this purpose, the difference of the impact of participation in accordance to the participation duration and attitude, the demographic property of participants, and the problem of Book debate club are investigated. The collection of data is achieved by questionnaires and interviews. In the analyzed result, the period and manner of the participation are very important factors. Also, the activation plan is proposed on the basis of the analyzed result of problems in reading debate club to contribute to the management of future University library's reading promotion program.

In this study, we investigated the characteristics of group discussion and classroom discussion in the scientific modeling of the particulate model of matter. 7th graders in Seoul participated in this study. We implemented science instructions based on the GEM cycle of scientific modeling. We analyzed the differences between group discussion and classroom discussion in three steps: exploring thoughts, comparing thoughts, and drawing conclusions. We also looked into the level of argumentations of the students in the modeling activities. The analysis of the results indicated that students generated a group model by extracting commonalities from each model of their group members, and then they evaluated and modified the group model by comparing the differences among the models in classroom discussion. The main step involved in group discussion was 'exploring thoughts', whereas in classroom discussion it was 'comparing thoughts'. Although the levels of argumentation among the students were generally low, most students participated with enthusiasm, as they expressed their interest and had positive perception in the modeling activities. As a result, the modeling activities were found to have positive influences on concept development. Some suggestions to implement the modeling activities in science teaching effectively were discussed.

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.

The previous study has assumed that dialogue and debate could not have been activated by the hierachical Confucian norm and political authoritarianism in Korean society. Political democracy has developed in Korean society since 1987. But many observers have pointed out that the culture of debate still remained undeveloped in Korean society. This study assumes that the key factor of determining the quantity and frequency of debate is the polilitical factor such as authoritarianism, but the determining one of qualitative dimension such as debate competence derived from the epistemological tradition. In order to ascertian this hypothesis, this study explored the epistemological basis of Confucian thoughts in comparison with the classical Greek thoughts. In classical Greek society, philosophers considered that the purpose of debate is to find and to ascertain the truth. Bur Confucian scholors didn't look upon questioning the truth. Instead they considered practicing or doing of the truth worthful. Therefore, in a society which were much influenced by the Confucian thought, the culture of debate could not have been developed.

We have web-based online discussion to implement active interaction and a variety of communicative activities. I have gathered the following research questions to study about the meaning of web-based online discussion as a mathematical communication teaching method. First, what changes are there in students mathematical communication ability in web-based online discussion\ulcorner Second, how do students evaluate the web-based online discussion experience\ulcorner In this web-based online discussion, groups of middle school first grade 34 students and each group had chatting at 8 times for 10 weeks. I analyzed what they had discussed by the prints that they had sent me by e-mail. I also surveyed what they had experienced and analyzed them. In this research, the online web based discussion has given positive influence on students' competence of speaking, writing, reading and listening which are crucial to mathematical communication. Students' mathematic thinking power improved and attitudes to mathematics have become more positive.
