The content and method of geometry taught in secondary school is rooted in 'Elements' by Euclid. On the other hand, however, there are differences between the content and structure of the current textbook and the 'Elements'. The gaps are resulted from attempts to develop the geometry education. Specially, the content and method for the proportional relations of geometric figures has been varied. In this study, we reviewed the changes of the proportional relations of geometric figures with pedagogical point of view. The conclusion that we came to is that the proportional relations in incommensurable case Is omitted in secondary school. Teacher's understanding about the proportional relations of geometric figures is needed for meaningful geometry education.

This study compares the two biggest Islamic organizations in Indonesia, Nahdlatul Ulama(NU) and Muhammadiyah. As previous studies focus on their theological and ideological aspects, this study tries to analyze not only their religious orientation but also position of religious leaders, organizational structure, leadership system, routine activities and susceptibility to new religious change. The second part of this paper deals with religious and socio-political backgrounds under which the two organizations were established and with differences in the ways of interpreting Islamic teachings. This will provide the basis for understanding the dynamics of their later development. The third part explores religious authority supported by both. For this, perspectives on established religious schools, rational interpretation of the Scriptures, mystical practices and hereditary succession of religious leadership are to be analyzed. In addition, the ways different attitudes towards religious authority have impacted on organizational structure are to be examined. The topic of the fourth part is leadership composition, and blood and teacher-student relationships among chairpersons are to be analyzed. The last part deals with how different orientations of the two have impacted on their activities and especially on the ways of accommodating new religious ideas. For this, the ways 'liberal Islamic thought' has been introduced, accommodated and negotiated in each organization are to be compared with. With these discussions, it is expected that religious orientations, organizational structure, leadership system and organizational flexibility of the two can be understood. This analysis can help to have a glimpse on Islamic development in Indonesia and of socio-cultural and political influences the two have exerted on Indonesian society.

Today manny contemporaries struggle to live because they disregard essential matters and indulge in materialism. They should not pursue wealth and prosperity and ought to find true meaning of life by studying death where one can reveal the essence of life. Zhuang Zi transcended death. His view of death is magnificent. This dissertation has ruminated on how contemporaries live and established righteous view of life and death on the basis of that. In addition, this study has researched what implications his view of death suggests to us today. There is no study as good as death. There is no great teacher as good as death in life. Studying death is studying a life. We can find life meaning and value through death. The matter of death is prone to be thought that a solution can be got only though existing religions. However, when it comes to Zhuang Zi's death, the matter of death can be resolved, not relying on religions. Zhuang Zi has played a role of our taking death in a positive way and relieving the fear of death. He has taught us that it is well off to adapt to the change of nature, leading to meeting our death in comfort.

The information society is characterized by rapidly increasing and changing information. Traditional models of learning and instruct on have emphasized forms of mastering the information in content domains. Storing information and being able to recall it has been central to formal education. But it is no longer possible to master content domains. This paper discusses constructivism as a shifting paradigm for educational research and practice in information society. Constructivism provides an alternative epistemological base to the objectivist tradition. Constructivism holds that there is a real world that we experience. However, the argument is that meaning is imposed on the world by us, rather than existing in the world independently of us. Meaning is seen as rooted in experience. The experience in which an idea is embedded is critical to the individual's understanding of that idea. From the constructivist perspective, learning is not a stimulus-response phenomenon. It requires self-regulation and the building of conceptual structures through reflection and abstraction. Problems are not solved by the retrieval of rote-learned right answers. The effective motivation to continue learning can be fostered by leading students to experience the pleasure that is inherent in solving problems chosen as one's own. Constructivism requires the change of the teacher's role from a knowledge transmitter to a coach or facilitator of student's understanding. Constructivist teachers inquire about students' understanding of concepts before sharing their own understandings of those concepts, and encourage students to engage in dialogue, both with them arid with one another. In Korea, the educational reform called open education has been spreading through out the country. There should be a paradigm shift in learning and instruction from objectivism to constructivism for better educational reform in Korea.

In this study, we compared the perception of general and specialist teachers about the software education that entered the classroom by the 2015 revised curriculum. For the comparison of cognition, the 17 - hour hourly curriculum, the statement of achievement criteria, and the curriculum were organized in grades 5-6, but the appropriateness of the inclusion of only textbooks in grade 6 was questioned. The general teacher had many opinions that all three items are appropriate. On the other hand, professional teachers were inadequate and many were. It is necessary to provide various opportunities such as the training for the recognition change in the future. In addition, positive keywords for the introduction of general and specialist teachers were derived as a result of analyzing the main keywords of the free - response opinions about the introduction of educational robots in the practical course curriculum and textbooks. However, general teachers showed differences in the use of post - adoption education, such as passive and passive keywords such as support, difficulty, and problems, and the use of specialist teachers and education. In the future, it seems that it is necessary to provide teaching support to elementary school teachers, to provide beginner level difficulty training.

Purpose: This study was conducted to describe the experience of school health teachers in regard to the COVID-19 pandemic in South Korea. Methods: We conducted a qualitative study using content analysis. Ten school health teachers were recruited from 6 elementary schools, 2 middle schools and 2 high schools in Seoul, using purposive sampling. They participated in semi-structured in-depth interviews in person or using an online communication system from January to February, 2021. Interviews were transcribed verbatim and analysed using qualitative content analysis. Results: Three main categories and nine generic categories emerged from the analysis. Firstly, it was discovered that school health teachers had psychological and physical stress to cope with COVID-19 due to the 1) fear of the unexpected infectious disease, 2) burden of having to deal with it alone, 3) breakdown of personal life and physical exhaustion and 4) heavy duty as a health teacher caused by the lack of an organic cooperation system with institutions related to school infectious diseases. Secondly, school health teachers had an increased sense of empowerment in regard to infectious disease management as a result of 1) feeling rewarded and appreciated and 2) gaining confidence and trust in infectious disease management. Finally, school health teachers experienced the urgent need for an effective response strategy for infection control because of the 1) confusion over infectious disease response due to lack of practical manuals applicable to the field as well as training, 2) disappointing response system without an expert response team dedicated to managing infectious diseases in schools, and 3) growing awareness of the need for change. Conclusion: It is expected that school health teachers' experience of COVID-19 will be used as important data for building effective and advanced school infectious disease response systems.

The study developed and analyzed programs that incorporate observable worldviews-based science education and education for sustainable development(ESD) in science classes to emphasize integration with the background of the times and achieve effective goals of science education aimed at cultivating scientific literacy. As a result of applying the program to actual high school students, students were able to see the transition to the worldviews of ecology in the process of considering various values and making decisions by identifying their own values. Students' worldviews were found to be at odds during the process of identifying their worldviews and approaching values in various aspects of the class due to the conflicting values of each curriculum and teacher worldviews. In the area of individual values, the worldviews should be applied in science education and understanding of the worldviews of teachers and curriculum contents is also required. Through this study, we hope that access to the area of individual values represented by the worldview in science education will help students change fundamental.

Korean film director Lee Joon-ik's two most recently released works, (2018) and (2021), introduce some changes to the world of male bonds, where bromance colors prevailed. It is a father-son or pseudo father-son relationship that has not been dealt with in the exploration of vary kind of intimacy and relationships between men in the 'Lee Joon-ik's films'. If depicts a blood-related father-son relationship, highlights the teacher-disciple relationship, or pseudo father-son relationship. In that respect, the films continue, change, and expand the relationship setting, the sense of problems in the previous film, and inevitably raise the issue of 'generation' and 'inheritance' required today by illuminating the father-son relationship.
