The purpose of this study is to investigate Home Economics(HE) teachers' perception of Home Economics curriculum perspective and their instructional culture, and to find out correlations between them. 210 questionnaires were used for analysis. The results are as follows. First, our research showed that the preferences of HE teachers with respect to curriculum perspectives were in the order of the interpretive, emancipatory, and technical perspectives. However, there was no consistency among findings in the preferences for the sub-elements of a curriculum. Second, our results indicated that HE teachers performed their role affirmatively in terms of instructional culture such as the 'cooperation between teachers', the 'class focused on student', and the 'learning materials preparation'. Third, there was a statistically significant difference in five elements such as the 'cooperation among teachers' between the HE teachers' curriculum perspectives and their instructional culture. Fourth, there was a statistically significant difference in the 4 factors of 'instructional culture' between the teacher group whose curriculum preference was clear and those group whose curriculum preferences was vague.

2015 개정 교육과정에서 컴퓨팅 사고력의 함양을 강조하고 있지만 컴퓨팅 사고력을 평가하기 위한 도구에 대한 개발이 미흡하다. 비버 챌린지 문항은 전 세계 60여개국의 정보 교육 전문가 집단이 약 1년 동안 공동 출제 및 검토를 통해 개발되는 문항이므로 문항의 타당도가 높다고 볼 수 있다. 다만 초기의 개발 목적이 평가도구로써 사용하기 위함이 아니었기 때문에 과연 컴퓨팅 사고력의 평가 도구로 사용할 수 있는 신뢰도를 가진 문항인가를 검증하기 위해 본 연구에서는 비버 챌린지 2017 그룹 III의 문항을 대상으로 문항내 적일관성신뢰도를 통계적으로 검증하였으며 그 결과 Cronbach ${\alpha}=.784$로 신뢰도가 높게 나타났다.

The purpose of this study was to investigate the perspectives on curriculum of secondary school home economics(HE) teachers, the HE teacher efficacy level, and the correlation between their perspectives on HE curriculum and the HE teacher efficacy. A questionnaire survey was carried out to the 500 HE teachers from middle and high schools across the nation, 215 questionnaires were used in the final analysis. The findings of this study were as follows: First, most of HE teachers had the biggest interest in interpretative perspective and some teachers had a interest in critical perspective. On the other hand, a few teachers only had a interest in technical curriculum perspective. Second, HE teachers who worked in the big cities tended to be more interested in interpretative perspective than those who worked in small cities. HE teachers from 25 to 40 years olds tended to be more interested in critical perspective than those who were more than 50 years old. Also, HE teachers with less than 15 years of experience tended to be more interested in critical perspective than those who had worked for more than 15 years. Third, the average of the HE teacher efficacy level was 3.69. The efficacy level of studying support was the highest. Then came class support, environment support, instruction strategy, and demands alternation in order. Fourth, there was moderate correlation between the interpretative perspective on curriculum of middle and high school HE teachers and teacher efficacy level in comparison with other curriculum perspectives.

The purpose of this study was to investigate how educational experience (teaching experience, experience participating in the Teacher Learning Community, curriculum training experience, and innovative experience working in school) of elementary school teachers affects the recognition and execution of curriculum and textbooks. For this purpose, the results of a questionnaire survey for elementary school teachers were analyzed by performing T-tests, One-Way ANOVA, correlation analysis, and regression analysis. The results were as follows. First, according to the teacher's educational experience, there were statistically significant differences in the recognition and execution of curriculum reorganization, and the recognition and dependence on textbooks. Second, there were statistically significant correlations among such variables as recognition and implementation of curriculum reorganization, and the recognition and dependence on textbooks. Third, the teacher's educational experience had a significant impact on curriculum reorganization and the dependence on textbooks. Curriculum restructuring in elementary schools is not an end in itself. What is also needed is to find and implement the best class plans for promoting the .meaningful growth and development of elementary school students. This study suggests that the dependence on textbooks should be lowered and the curriculum should be actively reorganized, and teachers should develop their expertise based on extensive educational experience.

The purpose of this study was to develop a rubric for assessing students' scientific argumentation. Through the analysis of relevant literature related to argument in science education for developing rubric, the procedure in development and the category in assessment for rubric were elicited. According to the general procedure in developing rubric, the standard for evaluating the argumentation derived three categories such as a form, contents, and attitude. The form category was further segmented into sub-functions composition, claim, ground, and conclusion in the whole. The category for contents was segmented into sub-functions understanding, credibility, and inference. And the category for attitude was set to sub-functions participatory level and openness. The standard for evaluating sub-functions in each of the categories formed in this way was minutely suggested with five stages. The rubric, which was developed on the basis of literature, was inspected through a regular seminar in one expert in science education and fellow researchers. The rubric, which was developed in the early days, was again modified by being verified on problem and improvement matter after being entrusted to four experts in scientific education. And, the finally-completed rubric indicated to be high with 0.96 in the content validity index by being verified the validity by the four experts in science education. The developed rubric will lead to being able to increase the understanding about demonstration in students, and to being available for being utilized as the criteria for developing the argumentation process program and for evaluating the argumentation activity.

This study was to analyze the learning effectiveness of multi-media based class by comparing with traditional classroom method. The "Distribution Working Subject" course that is one of the required courses of Vocational high school was selected and its contents were digitalized on MS Powerpoint for multi-media based class. The thirty students were sampled for each experimental and control groups. The homogeneity and learning achievement of sample groups were tested for experiment. Same teacher took the classes of two groups and delivered same contents of course. Only difference between two groups was the delivery method, one is traditional classroom teaching method and the other was the multi-media based class. The learning achievements and satisfaction of sample were post-tested in order to analyze the learning effectiveness by comparing two teaching methods. The results showed that there was a significant difference between experimental and control group in learning achievement after ANCOVA controlled pre-test as covariance(F=5.08, p<.05). It means that the learning achievement of multi-media based class was higher than that of traditional classroom group. The results also showed that a significant difference in students' satisfaction between two groups (t=5.57, p<.001). This study concluded that using multi-media in class could produce more learning achievements and satisfaction of students than traditional classroom method.

The purpose of this study is to examine 'Design Thinking' based Chemistry Class program as an education strategy for core competence of creative convergence talent. The program stages were modified and supplemented into eight stages, including 'Knowledge Understand', 'Empathy', 'Sharing perspective', 'Ideate', '1st Prototype', '1st Test', '2nd Prototype', and '2nd Test', so that the 'Design Thinking Process in Science Education' can be applied to the chemistry class. Considering the linkage between the 2015 and 2009 revised national curriculum, the achievement criteria were selected, and the lesson plans and student activity sheet were developed according to the themes to be met. Four thematic educational programs were developed and applied to Chemistry I for the second grade of high school students from March to August. The results were verified through qualitative data analysis of the class scene and pre- and post-test based on inventories of 'Empathy' 'STEAM educational competence', 'Problem solving process'. As a result of applying the developed program, 'empathy' showed a significant improvement in empathy with others and empathy with the problem situation. In 'STEAM educational competence', there was a significant enhancement in science and design competence. In the 'problem finding process', the problem definition, problem solution design, and problem-solving review were significantly improved in the 'problem-solving process'. The results of this study provided implications for the applicability of design thinking - based chemistry classes and its educational effect.
