We present a creative program model for encouraging the creative ability of gifted students by using overlapped patterns found in every day life. This model is based on the basic concept that the purpose of physics education is enlightenment from around the world. Combining both the Western perspective of creativity as productivity and the Eastern perspective of creativity as enlightenment, a Program for Enlightened and Productive Creativity(PEPC) for teaching inquiry was devised. This Program for Enlightened and Productive Creativity describes stages through which a student is guided to solve a problem using increasingly complex observation, inquiry, and experimentation. The use of this model in teaching is illustrated through a physics lesson of moire patterns using overlapping patterns found in our every day life. A case is made that PEPC can be applied to teaching general students as well as gifted students and in different content areas. PEPC model is applied to general students in middle school, scientifically gifted students and physics teachers.

The elderly rate in South Korea in 2015 is over 13.1%. Especially, the elderly rate in rural area is high. Senior community project in rural that is being promoted by the government. This study's purpose is to provide the reserch group-home for the elderly in Japan rural area. And this paper provided planning of group-home for the elderly in Korea rural area. For this study, respective 5senior housing of Korea and Japan were chosen as respresenting two nations, and every manager was interviewed on housing pattern. This study suggests the planning material as following. First, the effectiveness of the group-home are big. Especially, the elderly was far healthier. Design point is public space(living room, small living room, etc). Maybe, healthy group-home concept is that would be design by Korean traditional housing. Also important public space design is that would be inner courtyard-house, wood floor, Deachong, etc. Two group-homes will construct elderly welfare facilities in between. Otherwise that is need layout of a big public space. In the case of vacant house can used by considering of scale, structure, site condition. Closed school can used through so easy remodeling too. More often than not complex type(hospital, community heath center) was appeared in Japan rural area. In the case of Korea, recommend complex type in community health center and public building. In this case, considering communication, access, contact, group-home keeps on ground floor. In this paper, we hope to take a lesson from group-home planning source for the elderly in Korea rural area.

Deficient modes that cannot be always identified from different sets of measurement data may exist in the application of operational modal analysis such as the stochastic subspace identification techniques in large-scale civil structures. Based on a recent work using the long-term ambient vibration measurements from an instrumented cable-stayed bridge under different wind excitation conditions, a benchmark problem is launched by taking the same bridge as a test bed to further intensify the exploration of mode identifiability. For systematically assessing this benchmark problem, a recently developed SSI algorithm based on an alternative stabilization diagram and a hierarchical sifting process is extended and applied in this research to investigate several sets of known and blind monitoring data. The evaluation of delicately selected cases clearly distinguishes the effect of traffic excitation on the identifiability of the targeted deficient mode from the effect of wind excitation. An additional upper limit for the vertical acceleration amplitude at deck, mainly induced by the passing traffic, is subsequently suggested to supplement the previously determined lower limit for the wind speed. Careful inspection on the shape vector of the deficient mode under different excitation conditions leads to the postulation that this mode is actually induced by the motion of the central tower. The analysis incorporating the tower measurements solidly verifies this postulation by yielding the prevailing components at the tower locations in the extended mode shape vector. Moreover, it is also confirmed that this mode can be stably identified under all the circumstances with the addition of tower measurements. An important lesson learned from this discovery is that the problem of mode identifiability usually comes from the lack of proper measurements at the right locations.

The purpose of this study is to suggest the contents for geography education about East Asian cultural diversity. I chose "Human Relationship and Living-Habit" culture among East Asian diverse cultures and fixed 4 themes: family cultures, traditional cultures, friendship cultures and relationship cultures with other people. For making the lesson contents for East Asian cultural diversity, I analysed Geography 2009 Revised Curriculum and presented specific contents differently depending on grades. Until now, static and homogeneous cultures in East Asia have been emphasized mostly at school but cultures that are dynamic and related to students$^{\circ}{\phi}$ life are proposed in this study. Through understanding the differences of the East Asian cultures, it will be possible to expand mutual understandings among the East Asian people. This study will be a good alternative and paving the way for enhancing cooperations in East Asia.

Various data and methods are necessary to help students understand the science subject, and have interest in it. Most students like cartoons, and more easily memorize their contents. The purpose of this study was to verify the effects of science cartoon reading on the academic achiements, the levels of interests in science and scientific attitudes of elementary students The study subjects were four classes of the 6th grade of G elementary school in U city. Two classes were experimental group and the others were comparison group. The students of the experimental classes were encouraged to read science cartoon related to class contents at the beginning and ending for 5 minutes respectively in instructional time. And those of the comparison classes received general science lesson. The results of this study were as follows. First, the experimental classes encouraged to read science cartoon marked higher average score than comparison classes in post-test and the difference was meaningful (p<.05). This meant science cartoon reading treatment had the effect of improvement of the levels of interest in science of student. Second, the experimental classes marked higher average score than comparison classes in post-test but didn't show meaningful difference. This meant science cartoon reading treatment didn't have the effect of improvement of academic achievement of students in our study. Third, the experimental classes marked higher average score than comparison classes in post-test and showed the meaningful difference(p<.05). This meant science cartoon reading treatment had the effect of improvement of scientific attitudes of students. From the results thus far, we could tell that science cartoon reading had positive effects on the levels of interest in science and scientific attitudes of students in our study.

The purpose of the research undertaken for this paper was to demonstrate the effects of WBI on students' achievement and their reactions. WBI was adapted for use on the lesson Theme of Poems in Korean textbook for Middle School second graders. Hypothesis 1 was that there would be meaningful differences in students' achievement between the experimental group using WBI and the controlled group in a traditional instructive class. And the statistical calculations showed that the experimental group produced larger numbers in terms of both the average and standard deviation. Hypothesis 2 was that there would be the more highly rated outcomes from the experimental group applying WBI for students' interest, understanding, and concentration. The responses to a Questionnaire concerning stated items showed significant differences in favor of WBI class. Based on these analyses, this thesis represents an effort to potential application of WEI to learning of Poems, in light of research evidence that reveals its respective effect to further students' achievement and interest.

STEAM education has been introduced to resolve the existing problems of science education since 2011. However, as ICT develops rapidly, the future of the schools with various educational technologies is demanding for a new type of STEAM education. Therefore, the current research suggests CT-STEAM (Computational Thinking & STEAM) education, the new approach to provide integrated thinking based education with all sorts of computing devices. Firstly, the instruction model was developed as a fundamental step to introduce CT-STEAM in the real education scene. Then, lesson plan was developed as a implementation strategy, and it was tested for validity by computer education experts. It is hoped that the results of this study can enhance the understanding of CT and STEAM Education, also to provide baseline information to develop various teaching methods for integrated CT education.

The purpose of this study is to investigate science teachers' orientation toward scientific inquiry-based teaching. In this study, five middle school science teachers formed and participated in a teacher learning community for scientific inquiry-based instruction during one year. Data collection consisted of pre and post questionnaire and interviews, audio-recordings of teachers' collaborative lesson planning and reflection on teaching practice, and field notes of participant teachers' teaching practice and follow-up interviews. Data analysis indicated that there were four orientations toward scientific inquiry-based teaching. They were knowledge and beliefs about 'goals of scientific inquiry-based teaching', 'scientific inquiry-based teaching and learning', 'argumentation-based teaching and learning', and 'nature of science and science inquiry'. Teachers' collaboration in a teacher learning community would be effective in facilitating teachers' orientation to scientific inquiry-based teaching.

The purpose of this study was to investigate the change of elementary school students' conception on the movement of the moon, after teaching a lesson about the lunar phase which focused on concrete activities. The 396 subjects in this study consisted of intact groups of second, third, fourth, fifth, and sixth grade students. Pre-test and post-test instrument concerning on the conception in the movement of the moon were developed after reviewing the related literature and curriculum. Prevailing conceptions were identified by frequency of each conception. Then, the pattern of change and consistency of each conception were analyzed in comparison pre-test with post-test. To figure out the effect of teaching, the GEFT and the GALT instrument were administered to analyze it by gender, cognition mode and level. SPSS/WIN programs were used to process the data. The result showed that teaching 'movement of the moon' was the most effective in fourth grade. The effect of teaching 'changes in shape of the moon' was effective regardless of their sexes. Teaching 'changes in shapes of the moon' was more effective for the students whose cognitive modes were field-independent, than those filed-dependent. But the improvement by the teaching was not significantly different. The pre-score by cognitive level was significantly high in the order of the formal operational, transitional stage and the concrete operational stage. But the improvement of conception after teaching was high in the order of the concrete operational, transitional stage and the formal operational stage. That is to say, teaching was more effective as the cognitive level lowered.

Owing to the recent increased interest in wireless communication technology and rapid technology development, a range of applied technologies utilizing them are being released. In addition, at school, by adopting an attendance management system using wireless communication technology, attempts to solve problems caused by attendance books are being made. Representative attendance management systems include those using RFID, Bluetooth and clicker. Although these systems have solved the problem of wasting paper and time due to calling and writing attendance, they have other problems of generating additional expenses of purchasing or renting more equipment. To solve all of these problems, this paper suggests prototype system that can manage attendance by using NFC (Near Field Communication), which most smartphones provide. The attendance management system using NFC consists of two applications; one for professors and the other for students. The system solves problems, such as proxy attendance, loss of lesson time and additional cost by automatically managing attendance information using NFC and TCP/IP technologies.
