This study is purposed to research the present status and outcomes of adaption of science teacher system in elementary school. The subjects of this study are science teachers, schoolmasters, science supervisors, and 3rd$\~$6th grade students in western office of board of education, Gwangju Metropolitan city. It was found that there are 264 teachers who teach one subject and only two of them were science teachers. In elementary schools, most classroom teachers didn't want to be science teachers and schoolmasters or science supervisors could not afford to adapt science teacher system. After applying science teacher system to 3$\~$6th grade students during one school year, many students were improved in academic achievement and inquiring ability, and they have increased of interest and participation in science activities. This means that science class by science teacher is more effective than that by classroom teacher. Therefore, science teacher system should enlarge to science class in elementary school.

The purpose of this study is to analyze elementary school students' class contents and activities between the invention class for the gifted under the local education office by the 'Gifted Education Promotion Act' and that under the invention classroom by the 'Invention Promotion Act'. For this study, the survey was conducted to 1,788 elementary school students who attended the invention class for the gifted both under the local education office and under the invention classroom. The analysis of the survey showed that the students of the invention class for the gifted under the local education office had higher motivation and participation rate in class, higher interest in invention, and stronger significantly in a future oriented will than those under the invention classroom. The parents of the invention class for the gifted under the local education office showed more enthusiastic attitude to support their students, and had significantly stronger recognition that the participation of the students in the invention education for the gifted helped enter an advanced school than those under the invention classroom. However, the class contents of the invention class for the gifted under the local education office such as 'understanding the influence of the invention history and products on society', 'scientific inquiry skills for problem solving', 'technological and engineering abilities for creating an invention', 'developing knowledge and abilities about business and management by using a new invention' were not different from those under the invention classroom. In addition, discussion and presentation were not active in the class activities of the invention class for the gifted under the local education office. Therefore, the researchers should compensate and develop a program which can apply strategically differentiated class contents and class activities to the students who participate in the invention class for the gifted under the local education office by the 'Gifted Education Promotion Act'.

The purpose of this study is to analyze the characteristics and differences of gesture between career teachers and novice teachers in elementary science class. In order to analyze the gesture of elementary science teachers, gesture analysis framework was developed. The teachers who participated in the experiment were 2 beginner teachers and 2 career teachers. We analyzed 'bones and muscles', 'digestion', 'breathing', and 'excretion' of 'body' section in the second semester of 5th grade. The video recording of the class scene with the camcorder was recorded and analyzed by Observer XT. The results of this study are summarized as follows. First, the career teacher lessens unnecessary gestures than the novice teacher. During the class, the career teachers lessened the gestures not related to the context of the class. These differences were more prominent in the activities of the group with many unexpected situations than those of the teachers who prepared the class contents. Second, career teachers have more communication control act than novice teachers. Career teachers have often made adjustments to induce learner presentations or control unnecessary utterances. Third, career teachers efficiently interacted with learners using gestures that can enhance communication.

The purpose of this study is to explore how the practical knowledge used by an elementary school science teacher during learner-centered science instruction can promote elementary students' construction of positive emotion. Using an auto-ethnographic approach over a period of three months, the researchers collected students' interest diaries, post interviews with students, video recordings in science classes, and students' personal diaries and analyzed them by means of the constant comparative method. In this way, the researchers categorized the structure of the practical knowledge held by the teacher and explained how it was applied in learner-centered science instruction to promote students' construction of positive emotion. Three images of an elementary science teacher's practical knowledge emerged and can be categorized under the following headings: 1) 'From science classroom to science $caf{\acute{e}}$', 2) 'Pleasant experiment class for all students and the teacher', and 3) 'A science class for students who were marginalized'. These images were backed up by principles and rules, and the teacher came to embody these images as he implemented these rules. This study also discusses how the impact of a science teacher's practical knowledge on students' construction of positive emotions can be interpreted as promoting positive outcomes rather than negative sanctions, meeting students' expectation from lab activities, and meeting the specific needs of marginalized students in a science class.

In this paper, we propose an effective software education donation model for the social care class. The types of software education for elementary, middle, and high school for the social care class are in the order of after school classes, club activities, creative experiences, and regular classes. In elementary school students, it is effective to precede visual programming education based on block coding and to conduct curriculum convergence with SW and HW at the beginning, and high school students are carrying out text programming education like Python. Software education for social care class The contribution activity model can be classified into five types such as geographically difficult area, multicultural family areas, orphanage, reformatory, and basic livelihood security recipient. In addition, the survey results show that the students' interest in software education and their satisfaction are all very high at 96%. Effective software education for the social care class In the donation model, the lecturers consist of responsible professors, lecturers, and assistant instructors. Software training for the social care class is effective on a year-by-year basis, so that students can feel authenticity and trust. Software education contents focus on visual programming and physical computing education in elementary or middle school, and text programming and physical computing education in high school. It is necessary to construct a software education donor matching system that helps efficient management of software education donations by efficiently matching schools (consumers: elementary, middle, high school) and software education donors(suppliers).
