Subjects consisting of 335 middle school students were analyzed using arousal seeking tendency scales to determine the effect on student's scores on scales for physical education intrinsic motivation and physical education attitude. The data were subjected to frequency analysis, correlation analysis, reliability analysis, exploratory factor analysis, and multiple regression analysis as statistical methods. The results were as follows. In the subscales of arousal seeking tendency, novelty seeking positively influenced interest, efforts, and competence. In the subscales of arousal seeking tendency, novelty seeking positively influenced physical education attitude, but thrill seeking negatively influenced health and fitness only. In the subscales of physical education intrinsic motivation, interest and efforts positively influenced physical education attitude, while both competence and tension partly influenced it. These findings indicate that improving both attitude and intrinsic motivation of middle school students toward physical education would require a method of teaching and learning that encourages students′ novelty seeking in the subscales of arousal seeking tendency.

This study aims to theoretically and empirically establish the characteristics and component factors of creativity character of college students. Putting together preceding researches related to the concept and structure of creativity character through the theoretical approach, the in-depth interview and open survey were conducted targeting 70 specialists in education, education engineering, consultation meeting, and researchers' meeting about creativity character of college students. In the results, as creativity character for college students, creativity was classified into cognitive creativity and affective creativity while character was classified into moral character, social character, and emotional character. Especially, the creativity character of college students emphasized the importance of character more than creativity. Through such results, it aims to suggest a new perspective on creativity character of college students, and moreover to provide basic data to set up the research direction to develop a tool to measure creativity character of college students for follow-up researches. Also, it is considered to establish the theoretical, empirical foundation contributing to the establishment of teaching-learning method and education engineering qualitatively enhanced in the site of college.

This study is to point out importance of narrative as a way of learning values and interests for learners. Thus, geography value instruction models with narrative was developed and applied to teaching model. The results are as follows: First, narrative is useful to value education. Because narrative includes the contextual information, leaners are able to make a moral decision in respect of socio-cultural approach and to reach more truthful and practical decision with empathic understanding. Second, comparing with an expository text, the narrative text is more interesting, understandable, and preferred. Third, Web of meaning, one of scaffolding skills, is helpful to expand the scope of learner's thinking and group activity. Fourth, learner's awareness toward the topic changes. However, it is required to develop a practical method for elaborate assessment tool and for learners' active participation.

The application of reflex media in education has been widely used in the aspects of teaching & learning method, humanitarian education and the culture of school lives. It has been resulted from the generality of the applicable scope within conveying the information, propagation velocity, and the efficiency of the amount of conveyable information through the reflex. To utilize this kind of efficiency of reflex media in producing new graduation culture, I intend to show students the graduate reflex including their 3years' school lives and try to find out its effect from them. And then with this result I have studied the changes of the students behavior in the graduation ceremony. As a result I can notice that the intent of graduation reflex which aims to look back into their past and keep in mind it has been reflected to students. In addition I can ascertain their friendship and love for their school have been lifted while watching the reflex with laugh and cry.

Circuit theory is a systematic study that analyzes and designs the most basic circuits in the field of electrical and electronic engineering. Circuit theory courses are organized as major courses for one or two semesters in the second year of university, so that electrical and electronic engineering students must learn. Experimental courses are being together organized for students to enhance understanding of circuit theory and cultivate the skills and the abilities of circuit design through experiments with actual circuits. This paper is a case study on the teaching method applied in electric circuit design and experiment courses to enhance the learning effect on the experimental education that supports circuit theory. To do this, we propose a 15-week instructional model consisting of theory study, simulation, experiments, and design projects. In the proposed model, the simulation and preliminary experiment preparation process are reinforced to complement the theoretical concept and the design project is introduced to acquire practical circuit design skills as engineers. The results of five-year operation demonstrate the effectiveness of the proposed model.

The purpose of this study was to identify consciousness of bio-medical ethics of nursing and non-nursing students. The total mean scores of consciousness of bio-medical ethics between nursing(3.04/4) and non-nursing(2.88/4) were significantly different(t=6.79, p<.001). There were statistically significant differences between two groups in sub-categories of consciousness of bio-medical ethics: right to life of fetus, prenatal diagnosis of fetus, right to life of newborn, euthanasia, organ transplantation, brain death. The major predicting factors for consciousness of bio-medical ethics were experience of studying for biomedical ethics over 1 semester, experience of conflict for biomedical ethic problem, and ethical attitude in nursing department. Study results indicate that appropriate and various teaching-learning method for education of each department is deeded according to move up into a higher class with consciousness of bio-medical ethics, ability of decision making, critical thinking.

This study has been performed in order to achieve three objectives. They are as follows: To analyze, based on the research literatures, the nature of scientific inquiry ability and the characteristics of its constitutive elements. To identify inquiry skills and techniques essential to such areas as physics, chemistry, biology, and earth science. To develop instructional models and materials for enhancing inquiry ability on the part of high school students. It was found in the study that the scientific inquiry was interpreted in terms of different meanings according to the viewpoint of the person who are interested in the nature of science. The scientific inquiry has been viewed as the process of knowledge formation, scientific method, inquiry process or process skills depending on the epistemological, methodological, educational perspectives, respectively. It was also identified that certain kind of skills or techniques would be used for inquiry in only one specific area of the science. The skills and techniques are effectively learned when those are taught with specific knowledge in each area of the science. The model and materials for fostering scientific inquiry skills will be presented on the second part of the report.

Purpose: This study was conducted to examine the effects of simulation-based education regarding care in a cardio-pulmonary emergency care as related to knowledge, clinical performance ability, and problem solving process in new nurses. Methods: An equivalent control group pre-post test experimental design was used. Fifty new nurses were recruited, 26 nurses for the experimental group and 24 nurses for the control group. The simulation-based cardio-pulmonary emergency care education included lecture, skill training, team-based practice, and debriefing, and it was implemented with the experimental group for a week in May, 2009. Data were analyzed using frequency, ratio, chi-square, Fisher's exact probability and t-test with the SPSS program. Results: The experimental group who had the simulation-based education showed significantly higher know-ledge (t=5.76, p<.001) and clinical performance ability (t=5.86, p<.001) for cardio-pulmonary emergency care compared with the control group who had traditional education but problem solving process was not included (t=1.11, p=.138). Conclusion: The results indicate that a simulation-based education is an effective teaching method to improve knowledge and clinical performance ability in new nurses learning cardio-pulmonary emergency care. Further study is needed to identify the effect of a simulation-based team discussion on cognitive outcome of clinical nurses such as problem solving skills.
