Here we analyze a case of redesigned course named "Prospect of Nuclear Engineering" as an example of student-entered education which came to the fore of university education innovation. This course was reformed from lecture-based to student-centered class by changing the context as follows: Stimulating students by addressing various problems or episodes behind scientific and mathematical concepts in the history; Offering experimental project to perceive the importance of differential equations; Exploring the research status and issues of nuclear engineering and the ways of attacking them by discipline; Discussing the public acceptance of nuclear power plants. Small group activities using 'small group discussion' and 'peer-learning' have been applied in this course to enhance students' critical and creative ability. In the survey, students rated highly in the fact that they could actively interact with the peers and that they could think for themselves through 'small group discussion' and 'peer-learning' which is not just the way of conveying knowledge.

과학교육의 목표를 달성하기 위한 교수 학습 전략으로 과학글쓰기를 활용할 수 있다. 그러나 초등학교 학생들은 과학글쓰기를 어려워한다. 본 연구에서는 소집단 토론이 학생들의 과학글쓰기에 도움을 줄 것이라는 가정 하에 과학글쓰기 전에 소집단 토론을 도입하였으며 소집단 토론의 내용, 토론 중 나타난 학생의 특성이 과학글쓰기 세 영역(과학성, 논리성, 독창성) 향상에 어떤 영향을 끼쳤는지 살펴보았다. 연구를 위해 서울시 소재 초등학교 6학년 학생들 중 같은 소집단을 이루는 4명의 학생들을 연구 참여자로 선정하여 수업의 전 과정을 녹음, 녹화한 후 전사하였으며 학생들의 과학글쓰기 결과물을 수집하여 평가틀에 맞춰 세 영역으로 나누어 평가하였다. 연구 결과 첫째, 소집단 토론 내용은 과학글쓰기의 과학성 영역에 많은 영향을 주는 것으로 나타났다. 특히 성취도가 낮은 학생은 우수한 학생의 도움과 영향을 많이 받는 것으로 나타났다. 둘째, 과학글쓰기 영역 중 논리성 영역 중 구성의 체계성은 비교적 짧은 시간 안에 향상이 가능한 것으로 나타났다. 논지 전개의 일관성은 학생이 개방성이 부족하거나 토론에 대한 잘못된 생각을 가지고 있을 경우 부정적인 영향을 받는 것으로 나타났다. 올바른 논증의 형식과 논증의 목적, 의미에 대한 교육이 선행되어야 하며, 지속적인 토론과 글쓰기 교육이 필요함을 시사한다. 셋째, 성취수준이 중인 학생은 토론의 주제가 친숙할수록 독창성 영역에서 좋은 평가를 받는 것으로 나타났다. 과학글쓰기 수업에 참여해 4명의 학생은 모두 과학성, 논리성, 독창성 영역에서 향상되는 모습을 보였다. 특히 소집단 토론을 통해 성취수준이 낮은 학생이 과학글쓰기 능력에 가장 긍정적인 영향을 받는 것으로 나타났다. 그러나 성취수준이 높은 학생이 소집단 토론을 통해 과학글쓰기 능력에 어떤 영향을 받았는지를 구체적으로 밝히지 못했으므로 이에 대한 후속연구가 필요하다.

The purpose of this study was to examine the effects of small-group discussion and panel discussion as teaching and learning methods on college students' competencies of communication, problem-solving and leadership in a general education course. Participants were 52 college students, and they participated in the 13-session lessons. The data from questionnaires collected before and/or after the experiment were analyzed using a paired t-test and percent. The results were as follows. First, each 'total' competency in communication, problem-solving and leadership was increased statistically significant after the experiment. Second, in subdomains of each key competency, 'directed communication' and 'understanding the perspective of others' in communication, and 'divergent thinking', 'decision-making' and 'assessment' subdomains in problem-solving, and all subdomains in leadership were increased statistically significant after the experiment. Based on the results and students' opinions about discussions, the education implications for small-group discussion and panel discussion were discussed.

The purpose of this study is to examine what effects the experiment class to stress discussion of small groups in scientific experiment class of the elementary school has on scientific achievement and attitude on the science of the students comparing to the usual scientific experiment class. For that purpose, this study has divided 49 students at the 6th grade of the M elementary school in P City into test groups of 24 students and control groups of 25 students. Classes have been progressed by giving sufficient time to the test groups for discussion by each small groups after experiment while by allowing the control groups to finish the experiment with arrangement of the experiment results. Conclusions of this study include: First, the more familiar the experiment materials are and the easier the experiment procedures are to be operated by the students, the more actively the small group discussion activities have been deployed. It shows that the students need a certain level of background knowledge before experiment for vital discussing activities. Second, it is appeared that the test groups given the scientific experiment class stressing small group discussing activity have significantly high scores comparing to the control groups given the existing scientific experiment class. It shows that the small group discussing activities have effects on promoting understanding of the students on the scientific achievement for the scientific experiment class. Third, it is appeared that the test groups given the scientific experiment class stressing small group discussing activity significantly high scores on attitude about the science comparing to the control groups given the existing scientific experiment class. It is considered that the students could have opportunities to compare their own thoughts with others and to have reflective thought to change their thoughts through the small group discussing activity. As shown above, it shows that the experiment class to stress discussing activities is more effective to increase scientific achievement and attitude about the science than the scientific experiment class to get and arrange the experiment results from the existing experiment classes.

This qualitative research provides a situation model, which is designed for promoting learning of eigenvalue and eigenvector. This study also demonstrates the usefulness of the model through a small groups discussion. Particularly, participants of the discussion were asked to decide the numbers of milk cows in order to make constant amounts of cheese production. Through such discussions, subjects understood the notion of eigenvalue and eigenvector. This study has following implications. First of all, the present research finds significance of situation model. A situation model is useful to promote learning of mathematical notions. Subjects learn the notion of eigenvalue and eigenvector through the situation model without difficulty. In addition, this research demonstrates potentials of small groups discussion. Learners participate in discussion more actively under small group debates. Such active interaction is necessary for situation model. Moreover, this study emphasizes the role of teachers by showing that patience and encouragement of teachers promote students' feeling of achievement. The role of teachers are also important in conveying a meaning of eigenvalue and eigenvector. Therefore, this study concludes that experience of learning the notion of eigenvalue and eigenvector thorough situation model is important for teachers in future.

Purpose: Level of meta-cognition of students has been regarded as one of the crucial factors on web-based learning. This study aimed to describe interaction type in small group discussion of the nursing graduate students and to investigate learning consequences and interaction types in group discussion on meta-cognition level. Method: Twenty six graduate nursing students attending the class on-line at the K university in Seoul were included in the study. We measured their meta-cognition level and learning attitude. We also scored their individual and group reports as well as analyzed interaction type by reviewing the dialogue of the group discussion. Results: The participants showed low frequency of exploratory interaction and high frequency of integrative interaction in the cognitive interaction category. They showed frequent modification interaction in the meta-cognitive interaction category. Interestingly, the students with lower level of meta-cognition achieved significantly greater scores in the individual assignments. High functioning group consisting of the students with high meta-cognitive level produced greater group report. Conclusion: A new strategy is needed to encourage in-depth interaction in a group discussion of nursing students. Meta-cognitive level of the students should be considered to form a small group for discussion in order to improve group activities.
