In this study, we analyzed verbal interactions among 32 students in 7th graders' science cooperative learning at the levels of turns, interaction units, and conflict behavior units, and compared their verbal interaction patterns between the heterogeneous and homogeneous groups by students' collectivism. The relationships of verbal interactions with the achievement test scores and the increase of the achievement test scores were also investigated. In the analyses of turns, the distributions of the subcategories of the statements related to the task were found to be similar in both groups, and the frequency of 'explain' was highest. The frequencies of interaction units were higher in the homogeneous groups than the heterogeneous groups, and the frequency of 'symmetric interaction' was highest. In the heterogeneous groups, the frequencies of turns and interaction units for the students of high collectivism were higher than those of low collectivism. The frequencies of conflict behavior units were generally low, but the rates were similar in both groups. In the case of the homogeneous groups, the frequencies of 'avoiding' and 'competing' for the students of low collectivism were high, and the frequency of 'cooperating' for the students of high collectivism was high. In addition, the qualitative differences between the two groups were found in the interaction units and conflict behavior units. The achievement test scores and the increase of the achievement test scores were positively related with the sum of the frequencies of the statements related to the task.

This study aims at figuring out perception of teachers on the education of a child's personality development using concept mapping and demonstrating its importance. To recognize concept mapping of teacher's perception on the education of a child's personality development, the procedure of the research are as follows. The specific research results are as follows: First, based on the categorization, using multidimensional scaling and hierarchical cluster analysis, the results were concept mapping with 2-dimensions and five clusters. Second, dimensions of perception of teachers on the education of a child's personality development in concept mapping, showed virtue in left and performance in right, respectively, in X-axis, while environmental factor was in the upper area and personal factor was in the lower area, in Y-axis. Third, teachers' perception on the importance on education of child's personality development was evaluated in 5 categories as follows: 'Emphasizing adult's role'(M=4.45) was perceived as the most important among categories related to the education of a child's personality development. These results can be used for developing teacher's training program or an institutional supporting plan to raise performance of the education of a child's personality development in the future.

The purpose of this study was to design the coaching strategies for the problem based learning and examine 'the problem situation' to analyze the process of learning as it applies to the students' perception on problem based learning. The steps of this model were as follows: 1) presentation of the problem situation 2) confrontation of the problem 3) know/ need to know 4) definition of the problem statement 5) collection and sharing of information 6)generation of possible solutions 7) assessment of the best fit of solutions 8) presentation of the solution. Problem-based learning steps and coaching strategies were designed and implemented to 2nd grade high school students for the environment teaching unit. The results demonstrated that group discussion in the know/need to know step was most helpful for students to review what they know and generate solutions. At first students tend to state problems widely but through repeated group discussions they gradually clarified the problems. In the students' personal reflection notes and perception questionnaire of problem-based learning, many students especially showed difficulties in defining the problem statement. In contrast they participated actively in the learning process and express their opinions enthusiastically. Therefore, this study suggests that developing problem situation based on real context is of great importance for implementing a problem based teaming model continuously.

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.

In the verification and validation procedures regarding the safety-critical software of nuclear power plants for the attainment of the requisite license from the regulatory body, it is difficult to judge the safety and dependability of the development, implementation, and validation activities through a simple reading and review of the documentation. Therefore, these activities, especially safety assurance activities, require systematic evaluation techniques to determine that software faults are acceptable level. In this study, a safety case methodology is applied in an assessment of the level and depth of the results of the development and validation of a manufacturer in its targeting of the bistable processor of a digital reactor protection system, and the evaluation results are analyzed. This study confirms the possibility of an effective supplementation of the existing safety demonstration method through the application of the employed safety case methodology.

The Purpose of this study is to explore if people with intellectual disabilities can play a role as 'meaningful informants' in research process in Korea, by challenging the existing paradigm which consists of suspicion on the communication ability of people with intellectual disabilities and truthlessness of their statements, which results in ignorance on the covered life of people with intellectual disabilities. In this research, lessons which could learn through reinterpretation of my research experience are as follows. Firstly, the deficits of communication ability can be supplemented with restructuring interview instruments such as research questions, visual aids etc and adopting conversation analysis methods. Secondly, Suspicion on the truthlessness of their statements can be restructured by epistemological and methodological reinterpretation on the representation of social reality. Thirdly, the mechanism of exclusion and oppression according to the ignorance can be substituted by 'uncovering the life of people with intellectual disabilities', which can be basis of reconstructing the contents of programmes in the disability service centers and disability policies in the government. With these research results it could be argued that there needs to include people with intellectual disabilities as meaningful informants in the research projects funded by the government and also to provide people with intellectual disabilities with diverse roles in the research process by virtue of the development of qualitative research methods in the near future.

The purpose of the present study is to examine elementary gifted students' perceptions on bias against creativity utilizing concept mapping approach. Twelve elementary gifted students participated in the group brainstorming and produced 55 final statements. Based on these statements, the multi-dimensional scale and hierarchial cluster analysis using dissimilarity matrix were performed. Average stress value was .30 which is appropriate for a two-dimensional concept mapping study. In addition, a questionnaire survey using likert 6 points scale was carried out targeting 132 elementary gifted students to analyze the degree of sympathy on their anti-creativity bias perception. The findings are as follow: First, four categories were concluded dividing gifted students' perceptions on bias against creativity from the hierarchial cluster analysis with X-Y coordinate matrix, these were 'Contradictory attitudes to creativity', 'Low evaluation for creativity', 'Forced to predetermined rules and ideas', and 'Aversion to new things'. Second, elementary gifted students were sympathetic to the order 'Forced to predetermined rules and ideas'(M=4.16), 'Aversion to new things'(M=3.68), 'Contradictory attitudes to creativity'(M=3.55) and 'Low evaluation for creativity'(M=3.30). This study aims to examine, analyze and categorize various relevant factors related to elementary gifted students' perceptions on bias against creativity. Implications of the study related to the present and future creative education were discussed in depth.

The goal of this study was to discover factors of difficulties on learning Brønsted-Lowry acid and base focusing viewpoint of each definition. To achieve this, we were targeting statement of textbooks and perception of teachers that have a decisive effect on students' learning. Analysis of textbooks was performed for chemistry I of high school and EBS(total 6 textbooks) which dealt with Brønsted-Lowry definition. And a survey was conducted on 24 science teachers who had Brønsted-Lowry definition teaching experience. According to the textbooks analysis, characteristics of statement way were (1) statement without viewpoint of each definition, (2) convergent statement to Arrhenius. And features of teachers' perceptions were (1) teachers who have the only one viewpoint, (2) teachers with unawareness on coexisting reason of various definitions. All of these can be explained by absence from understanding viewpoints of Arrhenius and Brønsted-Lowry. To promote students' Brønsted-Lowry learning, students should obtain viewpoints of each definition. So we suggest that pre-service teacher training curriculum and statement way of textbook should reflect viewpoints of each definition.
