The purpose of this study is to obtain basic data for constructing a modeling practice program integrated with meta-modeling knowledge by analyzing the cognition level for each meta-modeling knowledge components through modeling practice in the context of the chemistry discipline content. A chemistry teacher conducted inquiry-based modeling practice including anomalous phenomena for 16 students in the second year of a science gifted school, and in order to analyze the cognition level for each of the three meta-modeling knowledge components such as model variability, model multiplicity, and modeling process, the inquiry notes recorded by the students and observation note recorded by the researcher were used for analysis. The recognition level was classified from 0 to 3 levels. As a result of the analysis, it was found that the cognition level of the modeling process was the highest and the cognition level of the multiplicity of the model was the lowest. The cause of the low recognitive level of model variability is closely related to students' perception of conceptual models as objective facts. The cause of the low cognitive level of model multiplicity has to do with the belief that there can only be one correct model for a given phenomenon. Students elaborated conceptual models using symbolic models such as chemical symbols, but lacked recognition of the importance of data interpretation affecting the entire modeling process. It is necessary to introduce preliminary activities that can explicitly guide the nature of the model, and guide the importance of data interpretation through specific examples. Training to consider and verify the acceptability of the proposed model from a different point of view than mine should be done through a modeling practice program.

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.

The purpose of this study is to analyze the status and gifted students' perception on curriculum implementation for gifted education at Busan Science Academy. For the purpose, we investigated the curriculum documents, the process of implementing curriculum and the result of the questionnaire. The questionnaire about the curriculum courses, teaching strategies and evaluation method was answered by 143 students at Busan Science Academy. The curriculum courses are composed of general courses and specialized courses: general courses comprise of Korean language, social studies, foreign languages, arts, and physical education. Specialized courses consist of mathematics, physics, chemistry, biology, earth science, information science. Elective courses are divided into basic elective courses and in-depth courses. Each in-depth course deals with more specialized content. The significant results of the questionnaire are as follows: First, according to gifted students' perception, the credits of specialized courses and in-depth elective courses need to be increased and the credits of general courses need to be reduced. Second, teachers at this school mainly use teaching strategies such as lecture, group activities and discussion, but the students prefer diverse teaching strategies such as lecture, discussion, experiment, individual research, problem solving and field studies. Third, students prefer a paper-and-pencil testing assesment rather than a written report assesment and lab experiment assesment. According to this study, the characteristics of the acceleration curriculum at Busan Science Academy were too intensive. Thus it is difficult to implement the enrichment education according to the demand of gifted students in this school. Therefore, this study suggests that we need to revise the curriculum courses of Busan Science Academy and develop contents and strategies for gifted education in science and mathematics.

The purpose of this study is to investigate the effect of role recognition of students participating in middle school soccer club activities applying sports education model on responsibility and self-directed learning. In order to achieve this purpose, 410 samples were selected from male students based in Busan using the convenience sampling method. Among them, and 370 data were finally verified through frequency analysis, exploratory factor analysis, Cronbach's α coefficient calculation, and correlation analysis using the SPS statistics 25.0 program. Finally, a regression analysis was performed for hypothesis testing, and the results were as follows. First, the awareness of the role of the student participating in middle school soccer club activities, which applied the sports education model, was found to have a positive effect in part on the sense of responsibility. Second, the role recognition of students participating in middle school soccer club activities, which applied the sports education model, was found to have a partial positive influence on self-directed learning. Finally, the responsibility of students participating in middle school soccer club activities, which applied the sports education model, was found to have a positive effect on self-directed learning in part. Therefore, physical education teachers should ensure that students can choose the right roles for themselves through various role experiences in soccer classes so that more active learning can take place.

In scientific argumentation, students can use rebuttals to escape uncertainty, which, in this case, can be defined as a vague and fuzzy feeling about other students' explanations. As rebuttals can play a critical role in the sophistication of arguments and the alleviation of uncertainty, this study aims to understand the dynamics of uncertainty and rebuttals by exploring the context of the uncertainty experienced by elementary school students in the argumentation of "Why did the kidney beans not germinate?" and to get insights based on the research results. Twenty fourth-grade students and their homeroom teacher in Kyong-Ki province, South Korea, took part in the research. Students engaged in argumentation in five small groups of four students. The researcher collected qualitative data through video transcriptions, student interviews, and field notes. In the data analysis, the researcher employed the constant comparative method to explore in what context students experienced uncertainty and how they used rebuttals. The results of this study were as follows: First, students tried to reduce their uncertainty through argumentation on why the kidney beans did not germinate. Second, students used elaboration-oriented rebuttals, personal opinion-oriented rebuttals, and blame-oriented rebuttals to reduce this uncertainty. However, when they used blame-oriented rebuttals, their uncertainty and negative emotions increased. Third, intervention by the teacher led students to stop using blame-oriented rebuttals. Instead, they employed elaboration-oriented rebuttals to explore why the kidney beans would not sprout, and finally, they escaped uncertainty by discovering an appropriate explanation. Based on the findings of this study, the researcher discussed how the interaction between uncertainty and elaboration-oriented rebuttals could shape and facilitate argument development in elementary school students.

This study examined the process of admission selection of vocational high schools and meister high schools and how the process have been utilized by schools to select appropriate students and by students to make decisions for application in consideration of their interests, aptitudes, and career paths. To address the purpose of this study, Focus Group Interviews(FGI) were conducted with three groups of participants: vocational high schools and meister high schools teachers, high school freshmen' parents, and middle school teachers who had many students advanced to vocational and meister high schools. The findings indicated that during the promotion process, schools made efforts to attract students with higher GAP and provided information mainly regarding employment rate instead of curriculum or program of majors. Since schools usually visited middle schools where higher GPA students were, not all students had balanced opportunities of high school promotions and enough information about majors. For the application process, the schools placed a high value on scholastic performance while students applied high schools considering their interests, aptitudes, and career paths. In terms of admission type and criteria, the high school teachers reported no big differences between special admission and general admission while students took advantage from the special admission process which was less competitive than general admission. Based on the findings, a number of suggestions were made in order to improve the process of admission selection of vocational high schools and meister high schools.

High school credit system refers to a system in which a student selects the desired content according to his/her subject and completes accumulated credits to reach graduation when a certain standard is reached. The purpose of this study is to identify the advantages and disadvantages to the technology and home economics education after the introduction of the high school credit system by analyzing the status of high school elective subjects in technology and home economics areas, and the perceptions and needs of teachers and experts as the introduction of the high school credit system approaches. A survey was conducted to all professors in the Department of Home Economics Education or Technology Education, along with a national sample of the secondary school teachers of Home Economics and Technology, and responses of 282 teachers and 36 experts were analyzed. Results are as follows: First, in general high schools, the formation and operation of elective courses in technical and home economics were very insufficient. Second, there was a large number of requests for the expansion of elective courses in technology and home economics among the high school teachers. Third, in order to take advantage of the high school credit system, it was recognized that elective courses in technology and home economics should be established not only in consideration of secondary school education, but in relation to their connections with majors in universities. Improving the structure of electives in this direction is expected to play a positive role in allowing elective courses in technology and home economics to contribute to ensuring students' free choice.

The purpose of this study was to analyze and extract the features of verbal interactions between teacher and science-gifted students in their classes. For the purpose of this study, authors observed 27 elementary science classes for the science gifted of three elementary teachers. To analyze the verbal interactions in the classes, the authors have adopted the theoretical background, which was based on Sinclair & Coulthard's Initiative-Response-Feedback pattern. Verbal interactions in the classes were analyzed by Kim's framework, which modified Jeong's framework. IRF patterns were derived from the verbal interactions of science classes for the science gifted. As a result, authors obtained some important features in IRF pattern. The most commonly used IRF pattern was the teacher's managerial question-student's short answer pattern, which was due to the regional policy for the science gifted. The teacher's delayed feedback as well as the teacher's question was meaningful for student's thinking ability. If elementary teachers consider the pattern, the strategy should be applied, which is depending on student levels and levels of contents. But three teachers did not show the characteristic verbal interaction regarded as a pattern strategy. In the future, inservice programs about verbal interaction are needed for the science gifted classes.

As we have entered into the 21st century knowledge and information society, the necessity of computer education has emerged and even its expectation is getting bigger. In spite of that, the present computer education neglects computer programming education which may be the basis of information, as understanding it only as the ability to utilize computer that deals with the usage of application program. Through the programming experience, students are likely tn understand abstract concepts on computer hardware, and to acquire knowledge needed tn solve problems given to them through computer. In this paper, on the basis of the significance and necessity in programming education, using a questionnaire, analyzed the necessity in programming education based upon responses of elementary school teachers to investigate the recognition analysis of elementary school teachers about programming education in elementary schools.
