In this study, we discussed about the implications of the idealization, which take an important role in physics, to the physics education. First, understanding of the idealization help the physics learning itself. This is because that various types of idealizations are included in the physics terms and concepts, derivation processes of physics laws and formulas, and explanation of natural phenomena and problem solving activities. Second, understanding of the idealization can help the application of the physics world to the real world. That is, by understanding the extent and the limit of idealization used in physics world, physics students can understand the discrepancies between the real world and the physics world. And also, by modifying or eliminating the idealization, students can extend the extent of understanding about how predictions based on the idealization used in the physics world will change. To do this, we suggested the application of computer simulation program in physics laboratories. Third, idealization take an important role in the inquiry learning for students' originality. The activities of identifying or controlling the variables, as one of the principal factors of scientific inquiry, need the appropriate establishment of the ideal conditions. And to analyze the limiting case or practice the thought experiments for understanding the impossible situation in the real world, ideal conditions also are needed. This study discussed above three aspects with various concrete examples and, with Park et al.'s study (Park et al., 1998), present the theoretical basis for the study of students' and teachers' understanding the idealization.

Recently, new teaching methods for communicating with teachers and students have been emerged according to the trends of decreasing the school-age population and the development of the mass media. We have applied teaching-learning model based on the flip learning to the college students in this work. As a result of the test for the customized flipped learning teaching-learning model in pre-class, the attendance rate of the major subject was 92.3% whereas that in liberal arts courses other than majors revealed 87.6%. This result for attendance rate shows that first year students in the radiology department have been actively participated in pre-class of the major subject than that of the liberal arts curriculum. From comparing the differences between the study group that was applied flipped learning in class and the non-applied group, the research group showed higher scores in knowledge, skills, and attitudes than the comparative group. In addition, more than 90% of the learners improved their responsibility, problem solving ability, creative thinking, cooperative ability, and communication ability through this learning program. From the test for the difference in the role of radiologists in the post class, the mean score was 4.40 for the group applied the teaching-learning model while that for non-applied group was 2.10. Hence, from such results, we see that this teaching-learning model is appropriate and needs to be extended to cultivate basic skills in radiology and relevant vocational education.

Modern society is the age of the information. As new information is springing up every day and pace of change becomes faster, the importance of communication skills is growing. The recent mathematics education is recognized as not a fragmentary mathematical knowledge or results of the learning, but a procedure of mathematical thinking, and the effective expression skill of their mathematical ideas and the ability to forward it to others are regarded very serious. As the method of mathematics evaluation, mathematical essay is introduced to replace the existing multiple-choice written test. This method assess the ability which students have, that express the reorganized knowledge and information according to given situation by themselves. Ultimately, it is expected to help that students get the higher order thinking skills such as logical thinking and creativity. However, definition of elementary mathematical essay is unclear, and proper teaching methods is lacking for each stage of elementary school students. Thus, in this paper, I have defined the concept of elementary mathematical essay and made a foundation of elementary mathematical essay research, then researched about the effective utilization of elementary mathematical essay using school education. Also elementary mathematical essay teaching-learning materials is developed and applied to analyzed the students' responses. Using this program, in real elementary school education, the implications has deduced.

The aim of this study was to find the effects of open-ended problems on mathematical creativity and brain function. In this study, one class of first grade students were allocated randomly into two groups. Each group solved different problems. The experimental group solved the open-ended problems and the comparison group solved the closed-problems. Mathematical creativity was tested by the paper test. And Brain function was tested by an EEG(electroencephalogram) tester. The results of this study are as follows. Firstly, this study analyzed how the open-ended problems are effective on mathematical creativity. This analysis showed that it had a meaningful influence on the mathematical creativity(p=0.46). Accordingly, we could find out that open-ended problems make the student connect the mathematical concept and idea and think variously. Secondly, this study analyzed the effect of open-ended problems on brain function. This analysis showed that it did not have a meaningful influence on the brain function(p=.073) statistically but the experimental group's evaluation was higher than comparison groups' at the post-test. It also had a meaningful influence on the brain attention quotient(left) (p=.007), attention quotient(right) (p=.023) and emotion tendency quotient(p=.025). As a result of such tests, we could find out that open-ended problems are effective on brain function, especially on the attention ability. With the use of the open-ended problems, students could show quick understanding and response. An emotion tendency is also developed in the process. Because various answers are accepted, the students gain an internal reward at the process of finding an answer. Putting the above results together, we could find that open-ended problem is effective on mathematical creativity and brain function.

The purpose of this study was to determine Enneagram personality type and the degree of clinical practice stress by personality type among nursing students, as well as to set a direction for student counseling and develop a management program. For this purpose, the Enneagram personality type inventory, developed by the Korea Enneagram Spirituality Institute, and a clinical practice stress scale were applied to juniors and seniors majoring in nursing in a district who were in clinical practice. The results were analyzed using an SPSS 25.0 program. Type 2 among the nine Enneagram personality types accounted for 47.66% while in the strength- centered area, the emotional area accounted for 64.84%. As for the degree of clinical practice stress by Enneagram personality type, Type 6 was most vulnerable to the training environment, Type 4 to an undesirable role model and conflicts with patients, and Type 5 to the burden of training tasks and conflicts in interpersonal relationships among the sub-areas of stress. As for the degree of clinical practice stress by the strength-centered area of Enneagram, the thinking type was most vulnerable to the training environment, an undesirable role model, the burden of training tasks, and interpersonal relationships, whereas the emotional type to conflicts with patients. To put these results together, nursing students varied in Enneagram personality type and differed in clinical practice stress by the strength-centered area, as well as by personality type. It is therefore necessary to provide nursing students with counseling and guidance through an analysis of their personality type.

The Industrial Revolution brought great development to the whole human history by the improvement of productive capacity. However, high speed development absorbed just on growth gave rise to resource depletion attack and economical inequality. If it might be neglected human society will meet unsustainable development situation. So UN has made effort to make sustainable development(SD) through global band together. SD concept considers it important to promote current development not giving damage to next generation's development. Then economy, environment and social integration should be harmonized and it demands governance for its actualization. SD gets to be a matter of common interest in education. New Millenium development Goals make African poor countries that are in blind spots of development advance toward gradual sustainable development by supporting programmes to these countries. Thus sustainable development education(SDE) is for future. It has an aim to give suitable education for all people who are all over the world. SDE tries to make health society and successful economical life for all. The concept of SD is found in the essential aims of Christian school and Christian education seeking justice and shalom. Christians are called as transformers for servant mission giving recover in corrupt world. Firstly, Christian school practise this mission making students think on Christian perspectives. Then it makes students serve for environment, economical fairness, social integration with servant mission. Also Christian school has a mission to seek both justice and shalom as a praxis beyond the intellectual dimension of education until fulfilling justice and shalom for all who are all over the world. Thus it can be that Christian school is an important educational institution for realizing sustainable development in that it is always to seek justice and shalom through restoration on the Christian educational perspective.

The purpose of the present study was to test hypothesis that, because it uses tri-dimensional sensory pathway which have been showed a higher rate of neural activities than uni- or bi-dimensional's, lab-activity-based instruction is more effective teaching strategy in learning science than verbal-based instruction. In the present study, manipulative teaching strategy that uses visual, somatosensory and auditory information pathway was regarded as a mode of tri-dimensional sensory inputs. In addition, verbal teaching strategy that uses mainly auditory and a little visual information pathway was used as a mode of bi-dimensional sensory inputs. Fifty-six students who failed to successfully solve two proportional reasoning tasks (i.e., pouring water tasks) were sampled for this research from a junior high school. The subjects were randomly divided into a manipulative or a verbal teaching group, and given manipulative or verbal tutoring on the use of proportional reasoning strategies and a test of proportional reasoning during instruction. The results showed that manipulative group's performance on the test of proportional reasoning during instruction showed significantly higher performance than verbal group's (t=2.45, p<0.02). The present study also discussed some educational implications of the results.
