The purpose of this study was to analyze 'how STEAM activities affect students' science process skills and science-related attitudes'. For more accurate, we have set 31 sixth-grade students from Gyeong-gi Province as an experiment group, and another 31 as a comparative group. We developed a STEAM program based on the educational concepts: Creative Design and Emotional Touch. Through pre-post experiment design, we have introduced TSPS, and Test of Affective Aspects. For TSPS, the comparative group scored higher average grade before the process. After the process, however, the experiment group exceeded the other. The result was considerable enough to verify that the science process skills were bolstered through the STEAM program(p<.05), Similar result was derived regarding the science related attitude. Students in the comparative group originally showed higher degree of interest to science. When the STEAM program was carried out, the standing reversed. The increase in the number of science related attitude indicates the program valid(p<.001). Furthermore, when we asked the students who participated in the experiment how they recognized the STEAM activity, we received positive answers: they consider the program efficient and well suited to the class environment. Conclusively, the STEAM program was proven to be effective for improving science process skills and attitude, and was perceived affirmative.

Gifted children cultivate their many talents through experience. For the purpose of revealing the talents or abilities of gifted children, it is necessary to provide them with various types of environment for their exploration from the early stage of their school age. In addition, knowing their concern, aptitude and interest from the early stage of their school age will be much helpful for them to grow, advance and search for their future career path. Accordingly, the purpose of this study is to examine the definitional and cognitive characteristics of gifted children through tests on the creative disposition, creative thinking power, multiple intelligences and morality of gifted children at the early stage of their school age in order to provide basic information on the gifted children studies. Accordingly, 90 gifted children were selected as the participants of this study through observation and recommendation. The result showed much difference between the second grade and the third grade in their creative disposition, creative thinking power, multiple intelligences and morality according to school year. As for the difference according to gender, the second grade female students showed meaningful differences in the sub-domain of creative disposition, multiple intelligences and morality and the third grade showed no differences. Such study result shows that students in upper school year clearly have their own sense of purpose.

We investigated middle school students' awareness of Han-style(Korean cuture) in order to promote it, and developed and applied the Teaching-Learning Lesson Plan according to the traditional clothing culture contents related to Han Style. We selected 5 major fields representing Han Style including Han-gul(Korean alphabet). Han-sik(Korean food). Han-bok(Korean traditional clothes). Han-ji(Korean traditional paper), and Han-ok(Korean traditional house). We analyzed the contents of the food, clothing and shelter in 6 types of high school testbooks under the revised 7th national curriculum, and chose seven traditional clothing-lifestyle culture contents. Also we developed 14-period processes and materials(9 for teachers. 9 for students and 3 for and applied it to usual classes. The mean score of middle school students' awareness of Han Style in the post-test was significantly higher than that in the pre-test. Students evaluated it positively that the classes could raise the pride on the Han-culture and provoke the interest in it through the direct experiencing activities. We suggest that the various themes on Han-style should be developed, and the theoretical classes on the identity as well as the experiencing activities on it.

Moral education is essential to the military in fostering elite warriors to have clear sense of their nation and the security, while arming themselves with military spirit that strives for victory. To reach this goal, various moral education has been set forth through boot camp training, academic education, unit training, etc. depending on various subject and supporting agencies in question. Also, in order to heighten the effect of the education, various attempts to combine concert-style cultural activities with the programs are carried out. However, the ultimate goal for this moral education is to facilitate soldiers to voluntarily set their minds and will in combat, and the current education system lacks that motivation as it concentrates mostly on educating knowledges about nationality and security. Under such circumstances, various units have attempted to raise morality in creating many public and media activities within the unit, which proven to be successful. In theory, the usual definitions in the field of education such as emotion, interest, attitude, and personality can be expanded upon with public and media activities. With this in mind, we have researched on how effective this method is by conducting various public and media activities in multiple units, total of 531 soldiers, starting from June to July of 2016. As a result, these activities brought positive effects on young soldiers to build pride in their assigned units, and also increased their willingness to carry out their assignments and missions. Through this research, we drew to the conclusion that unit-level public and media activities, which was solely used for gaining trust and communicate with the general civilians, can be used to boost the soldiers moral strength and help them express the strength in action.

This class is aimed at making teaching-learning in the dress unit effective, triggering students' interest in it, enhancing their understanding and offering basic materials for the e-Learning development about clothing instruction in the subject of technology & home economics. To make the concrete situational learning effective and provide realistic learning environments, learning contents were implemented so that the learners themselves could manipulate the contents by clicking. How to wear clothing according to learners' individuality was presented in order to trigger the learners' attention and motivation using the latest clothing pictures from the Internet shopping mall, and the dress fashion pictures of their peers. The result of this study can be summed up as follows. First, the implementation of learning materials with which simulation manipulation and visualization were possible could make the students reach the learning goals easily. Second, teaching-learning activity could be made more effective using audios, images and moving pictures rather than written texts. Third, learning the dress unit, which is especially related with a new fashion, made the most of the advantage of e-Learning by providing realistic and lively learning materials in a timely manner. And it triggered learners' motivation by providing pictures or moving pictures related with their real life. Based on these research results, this study suggests further research to develop e-Learning contents using various multimedia authoring tools as well as the ones applied to this study in learning the dress unit. It also suggests that the database of teaching-learning materials be constructed to securely prepare abundant instruction materials.

This study aims to develop the NABI program, which can be applied to science education in school, to realize 'Science Education through Nature' for today's students. The first NABI program was developed based on the viewpoints of education and teaching methods of Nature-Study, and it was revised as the second NABI program through experts' workshop. The second NABI program was applied to 24 third-grade students of an elementary school. The possibility of applying the program to school science education was explored through the analysis of students' qualitative data, along with surveys that were completed by 24 students and 79 current teachers. As a result of applying the program, students were curious about and communed with nature. The program could also realize the learner-centered education and integration of subjects, science with literature and art. The students were interested and wanted to continually participate in the NABI program. The teachers' evaluation of the program deduced that the relationship between the program presenting Nature-Study ideologies could be applied to science education in school. In conclusion, it was found that the NABI program was well reflected in the scope of the Nature-Study, and it can be applied to science education in school. The NABI program proceeds in nine steps: 'Accepting - Choosing - Selecting the common subject - Ice Breaking - Making relationship - Observing - Scaffolding - Expressing - Sharing'. The NABI program is a good way to realize the essence of science education, 'Science Education through Nature', for today's students.
