In the trend toward globalization, cross-cultural teams in organizations are becoming more and more common. In particular, the influence of China and Western Europe on the global economy is getting increased. With this trend, it is important to understand cross-cultural characteristics for group decision making in managerial environments. This study aims at analyzing cross-cultural differences between China and Western Europe in light of the effect of group discussion in group decision making. An experiment simulating a decision of a car purchase was conducted. A total of 48 subjects (24 Chinese and 24 Western Europeans) assigned in decision groups were asked to judge relative importance ratios of nine factors affecting their purchase decisions using the AHP program developed for the experiment. Three dependent variables (consistency, satisfaction, and consensus) were measured. Chinese were slightly more consistent than Western Europeans in discussion-involved group decision making. In terms of decision satisfaction, Western Europeans were more satisfied with discussion-included decisions than discussion-excluded decisions. Chinese, on the contrary, did not show a significant difference. There was no significant difference between two cultures in decision consensus.

The purpose of this study was to analyze the effects of storytelling and discussion types on the language development of young children. 32 treatment sessions were applied to the two experimental groups and the control group(N=151) during 16 weeks. One experimental group children discussed among themselves while the other experimental group children did with teacher. The control group children listened to storytelling by their teacher. Findings are as followings. Children of two experimental groups discussing on storytelling gained higher scores in vocabulary test and reading test than those of control group. The first experimental group discussing about storytelling with teacher gained higher scores in comprehension test than the second experimental group debating among themselves. But, there was no statistically significant difference on vocabulary and reading tests between two experimental groups. It was statistically significant difference on meaning test between two experimental groups.

본 연구는 수학적 사고를 토의를 통해 언어로 표현함으로써 타인과의 의사소통을 통한 반성적 사고를 유발하는 구성주의적 토의식 학습이 수학에 대한 태도와 수학 학업 성취도에 효과가 있는가를 살펴보았다. 연구 문제를 해결하기 위해서 서울 시내에 위치하고 있는 초등학교 3학년 1개반(30명)을 실험집단으로하여 구성주의적 토의식 학습을 하고, 다른 한 학급(30명)은 비교집단으로 하여 일반적인 수학학습을 6주 동안 시행하였다. 그 결과 다양한 수학적 상황과 의문점들을 토의에 의해 해결해 가는 학습 방법, 즉 자신의 사고를 수학적으로 의사소통해 나가는 구성주의적 토의식 학습은 수학에 대한 태도 중 자아개념과 교과에 대한 태도를 긍정적으로 변화시켰으며, 교과에 대한 학습 습관 중 자율학습과 학습기술 적용에 있어서 학생들을 긍정적으로 변화시키는 데에 효과적이다. 또한 구성주의적 토의식 학습은 일반적인 수업보다 학업성취도면에서 더 좋은 결과를 보였다. 그러나 본 연구가 3학년의 30명 재적의 한 개 반만을 대상으로 하여 학생들이 보인 결과를 분석한 것이므로 통계적으로 좀 더 유의미한 결론을 얻기 위해서는 다양한 학년과 다양한 환경의 학생들의 결과를 알아볼 필요가 있다.

The purpose of this study was to compare the effectiveness of programmed instruction versus lecture and discussion method on the knowledge of basic reference sources among undergraduate library and information science students. The hypotheses of the study were: 1. Programmed instruction will be more effective than the lecture/discussion method with regard to academic achievement. 2. There will be a significant difference in learning time between the experimental and the control groups. Seventy-eight library and information science students were participated m the study from the two universities in Chungchong Province. A programmed instruction manual, including 4-types of reference sources-dictionary, encyclopaedia, bibliography, indexes and abstracts, 40-item multiple choice post-test, and a questionnaire for the students' attitude toward programmed instruction were developed specifically for this research. The post-test only control-group design was selected for this experimental study. Students were given instruction on the specific reference titles in dictionary, encyclopedia, bibliography, indexes and abstracts. The control group was instructed by the lecture and discussion method while the experimental group completed a programmed instruction manual by themselves. Both the control and the experimental group were tested right after the instruction of 4-types of reference sources. In addition, a questionnaire asking students' attitude toward programmed instruction was administered to the experimental group. The findings from this study are summarized as follows: 1. The results showed that there were no significant difference in the mean of the post test score between the two groups. Therefore, programmed instruction is viable as an alternative method of instruction in the teaching of reference sources. 2. There was a significant difference in the mean of time spending for the leaning of bibliography, indexes and abstracts between the two groups. Accordingly, programmed instruction proved to be more efficient than the conventional lecture/discussion method in terms of learning time. 3. Students showed positive response to programmed instruction and evaluated it very interesting and challenging. In conclusion, the programmed instruction method was just as effective as the lecture/discussion method in the teaching of reference sources. And students' attitude toward the programmed instruction was favorable enough to secure a continued use of this method for the teaching of reference sources.

판단과 의사결정 연구에서 사람들이 판단 대상과 무관한 정보에 의해 영향을 받아, 예측 가능한 방향으로 편향이 일어날 수 있다. 이런 편향은 법적 판단에서도 나타난다는 연구도 많다. 그 중 하나는 피고인의 성격증거에 의해 유도된 편향이다. 본 연구에서는 성격증거로 편향을 유도한 다음, 판단자의 사고를 촉진하는 활동을 통해 편향을 감소시키는 방안을 모색하였다. 실험 1에서는 대학생 121명을 대상으로 하여 토론, 반사실적 사고와 토론, 그리고 반사실적 사고와 동료평가를 한 경우로 나누어 어떤 방법이 피고인의 성격증거로 유도된 편향을 줄이는데 효과가 있는지를 알아보았다. 연구결과 탈편향 활동을 한 집단은 통제 집단보다 유의미하게 편향이 줄어들었지만, 세 가지 다른 탈편향 활동을 한 집단들 간에는 감소량에서 차이가 없었다. 동일한 설계와 절차로 일반인 125명을 대상으로 실시한 실험 2에서는, 대학생 집단과는 달리, 반사실적사고와 토론을 병행한 집단에서만 유의미하게 편향이 줄어들었다. 종합 논의에서는 대학생과 일반인 간에 왜 이런 차이가 나타났는지에 대한 탐색과 연구의 한계점, 그리고 향후 연구방향에 대해 다루었다. 본 연구는 탈편향 전략이 피고인의 성격증거로 인해 발생할 수 있는 오판을 축소시킬 수 있음을 확인하였다는 점에서 의의가 있다.

This main purpose of this study was to assess the effects of two different types of ethics education on the moral judgement of clinical nurses. One type was free discussions among nurses with given specific moral issues and the other type was discussions guided by experts on specific moral issues. The study employed a quasi-experimental, nonequivalent pre test-post test design using two different control groups. The conceptual framework of the study was derived from the Kohlberg′s Moral Development Theory (1969) and the Greipp′s Ethical Decision-Making Model (1992). The data was collected during the period of October 14 through December 15, 1998. Sample consists of 32 nurses working in the ICU who met research criteria. 16 nurses were assigned to the free discussion group and 16 nurses to the group for the guided discussion with experts group. For the pre-test, the DIT which was developed by Rest (1984) and JAND by Ketefian (1998) were used with some modification by the author. After the education, only JAND was used to assess the changes in moral judgement. The collected data was analysed using SPSS PC program. The findings are as follows: 1. There was no significant difference between two groups in their general characteristics. Only difference which was statistically significant between two groups was that realistic score on Case 3/Medical Research and Autopsy was higher in the free discussion group. 2. Hypothesis 1: "There will be a difference on the moral judgement of nurses before and after they receive an ethics education". This hypothesis was supported partially. Those who had low scores on moral judgement before the education tended to have higher scores after the education on the same issues. And, after the education, the nurses tend to give lower scores on the dilemmas they had experienced frequently at work; while giving higher scores on those dilemmas they had no prior experience. 3. Hypothesis 2: "The effect of education may differ depended upon the moral development index [P(%)] score of nurses". The effect of education was different depend on moral development level. The group who′s P(%) scores was low at the pretest has higher scores in realistic moral judgement after the education, while the groups with middle or high P(%) scores went down after the education. These changes were statistically significant in some cases, thus, the Hypothesis 2 was partially supported 4. Hypothesis 3: "The method of ethics education will have different effects on the moral judgement of nurses". Even though several nurses attended the guided discussion stated that the education program broadend their perspectives the difference between two groups was not significant and this hypothesis was not supported. In conclusion, both types of ethics education had helped the nurses to acquire the skills to deal some nursing dilemmas. The effects of ethics education may differ according to the moral development index - P(%) score. However, because of some of the limitations of this study, mainly small sample size, short term education, unable to control other variables which may affect moral judgement of nurses, further research is warranted.er research is warranted.

The purpose of this study is to examine the effectiveness of video-and discussion-based smoking cessation intervention for adolescents. And this study is intended to provide a basic database for the development of health education, to serve health promotion for adolescent. The subjects were 472 high school students in K yungkido. The data was collected from September 23th to October 31 st, 2002. The data was collected by the measurement of knowledge, attitude, and intention toward smoking. Pre-research was conducted before smoking cessation education and post-research was performed twice, immediately after the education and 4 weeks later. Collected data was analyzed by using the SPSS 10.0 which is a computational statistical program. The results of this study are as follows： 1. Total knowledge points in smoking cessation program-based group are higher than any other groups and the statistical difference is significant. 2. The students' attitude points in experimental groups are higher than that of the control group and the statistical difference is significant. However, the meaningful statistical difference disappeared after 4 weeks. 3. The non-smoking students' intention points do not show any significant difference. And the smoking students' intention points in experimental groups are higher than that of the control group but the statistical difference is insignificant. 4. There are correlations among knowledge, attitude and intention toward smoking： knowledge and attitude are negatively correlated, knowledge and intention are positively correlated for non-smoking students, and for smoking students, attitude and intention have a negative correlation.

One class of grade 7 was chosen as a control group, and the other as an experimental group. The control group watched only a film of motion in weightless situation, but the experimental group had a contrastive discussion before watching the film. In pretest, pupils were given contrasted views between the pre-Galilean and post-Galilean about falling and horizontal motion of bodies, and asked to choose one from two points of view and to write the reason why they choose it. After the pretest, control group students watched the same film as the experimental group did. On the falling problem, the control group ignored the contents of the film or regarded related contents as not related contents. However, through the contrastive discussion, experimental group pupils reconstructed their past vague ideas and noticed the cause of falling which was not perceived by the control group. On the horizontal motion, some in the control group agreed with post-Galilean view points after watching the film. Some of the pupils in the experimental group agreed with the post-Galilean viewpoint after performing the contrastive discussion. However, most of them agreed after watching the film. So we can conclude that the contrastive discussion which helped students to reconstruct their ideas made the difference between the two groups.
