In the 2015 revised curriculum, 'Integrated Science' was established to increase convergent thinking and designated as a common subject for all students to learn, regardless of career. In addition, the 2015 revised curriculum introduced 'competence' as a distinctive feature from the previous curriculum. In the 2015 revised curriculum, competencies are divided into core competencies of cross-curricular character and subject competencies based on academic knowledge and skills of the subject. The science curriculum contains five subject competencies: scientific thinking, scientific inquiry, scientific problem solving, scientific communication, scientific participation and life-long learning. However, the description of competencies in curriculum documents is insufficient, and experts' perceptions of competencies are not uniform. Therefore, this study examines the perceptions of science subjects in science high school teachers by deciding that comprehension of competencies should be preceded in order for competency-based education to be properly applied to school sites. First, we analyzed the relationship between achievement standards and subject competencies of integrated science through the operation of an expert working group with a high understanding of the integrated science achievement standards. Next, 31 high school science teachers examined the perception of the five subject competencies through a descriptive questionnaire. The semantic network analysis has been utilized to analyze the teachers' responses. The results of the analysis showed that the three curriculum competencies of scientific inquiry, scientific communication, scientific participation and life-long learning ability are similar to the definitions of teachers and curriculum documents, but in the case of scientific thinking and scientific problem solving, there are some gaps in perception and definition in curriculum documents. In addition, the results of the comprehensive analysis of teachers' perceptions on the five competencies show that the five curriculum competencies are more relevant than mutually exclusive or independent.

The purpose of this research is to analyze content elements of Housing area in 2013 middle school Technology Home Economics textbooks 1 and 2, total of 22 according to 2009 revised curriculum. The analysis method was content analysis, focusing on contents of main text, tables & figures, reading material, and activity materials by their content elements. This research will contribute in obtaining suggestion for the post curriculum/textbook development and helping teachers to perform a lesson. The results are as follows. First, Housing area included 1 to 4 content elements per each units, from 2 chapters and 6 units. The content elements stated in Home economics curriculum were total of 16 which consists of 'the meaning of housing,' 'housing types,' 'family forms,' 'family life style cycle,' 'life style,' 'neighboring environment,' 'co-living values,' 'air environment,' 'heat environment,' 'light environment,' 'acoustic environment,' 'space division,' 'circulation', 'effective use of space,' and 'sustainable dwelling practice.' All of these components are dealt with in every textbooks. Second, the numbers of content elements provided in each textbooks were the same, however they showed difference in their contextual aspect. Some contents need supplemental material for their lacking content element. Others need proper understanding of the concept because some showed different contents from the appropriate content elements. Third, repetitions in content elements were observed, the contents of 'co-living values' in textbook 1 and 'sustainable dwelling practice' in textbook 2 were similar in terms of eco-friendly housing, co-housing and universal housing. These two content elements should be merged as one next curriculum, or should be stated together in one subunit.

This study attempted to analyze the achievement criteria of the 2015 special curriculum middle school physical education curriculum based on Bloom's new education goal taxonomy. To this end, 184 sentences based on the common curriculum and basic curriculum achievement standards of the relevant curriculum were analyzed into a total of 24 combinations of 4 dimensions of Bloom's new education goal taxonomy and 6 dimensions of cognitive courses. The results of the study are as follows. First, in the case of the special curriculum physical education and middle school achievement standards, unlike the analysis of the basic curriculum of elementary schools shown in previous studies, the 'procedural knowledge-applying' combination was the most common, and it was confirmed that there was a hierarchy by school level. In addition, the dimensions of knowledge and cognitive processes were relatively diverse, confirming the key points of physical education and middle school classes for disabled students. Second, in the case of the common curriculum among the lower curriculum, knowledge and cognitive process dimensions were relatively diverse except for cognitive process dimensions such as 'remember', and higher knowledge and cognitive process dimensions such as 'metacognitive knowledge' and 'creative'. Third, in the case of the basic curriculum among the lower curriculum, the 'procedural knowledge-applying' combination was excessively concentrated at 60.7%, which was analyzed to require improvementsary.

In this study, how to instruct the computational estimation of addition and subtraction was considered from the perspective of a 'intended-written-implemented' multi-dimensional curriculum. To this end, the 2015 revised elementary school mathematics curriculum as a intended curriculum and the 2015 revised first~sixth grade textbook as a written curriculum were analyzed with respect to how to instruct the computational estimation of addition and subtraction. As an implemented curriculum, a research study was conducted in relation to the method of instructing teachers about the computational estimation of addition and subtraction. As a result, first, it is necessary to discuss how to develop the ability to estimate and set it as a teaching goal and achievement standard in a separate curriculum to instruct it with learning content. Second, it is necessary to provide an opportunity to learn about various estimation methods by presenting specific activities so that students can learn the estimation itself in a separate operation method. Third, in order to improve the computational estimating ability of addition and subtraction, contents related to the computational estimation need to be included in the achievement criteria, and discussions on the expansion of the areas, and the diversification of the instructing time will be needed.

In vocational high schools, mathematics classes aims to improve students' mathematics-applying ability as the employ ability. However, these classes are based on the national curriculum of mathematics likewise general high schools. In this study, we develop and present the materials of teaching and learning mathematics for teachers and students in vocational high schools. We analyze the Test for Enhanced Employ Ability and Upgraded Proficiency (TEENUP) and 2015 revised national curriculum of mathematics, and consider how teachers can use this curriculum to enhance employ ability. As a result, materials of teaching and learning mathematics should be developed in terms of use of curriculum based on teachers' didactical understanding. Moreover, we present the developed materials as examples reflecting on the framework of TEENUP and connecting the 2015 revised national curriculum of mathematics. Based on these results, we draw some recommendations for applying and developing material of teaching and learning mathematics.

The purpose of this study is to activate Home Economics integrated career education for strengthening career development competency in a career education intensive semester & grade system. To do this, the trend of subjects-integrated career education, and the relationship between achievement standards of Home Economics in high school and career development competency were analyzed, methods for Home Economics subjects-integrated career education were investigated, then a case study was developed. The main research results of this study are as follows. First despite the importance of subjects-integrated career education, there are much rooms to improve in operation of the career education intensive semester & grade system. Therefore, the systematic preparation for subjects-integrated career education is required at the time of application of the 2015 revised curriculum and the expansion of the career education intensive semester & grade system. Second, all achievement criteria in three domains of Home Economics were shown to be highly related to career development competency. Eventually it could be confirmed that the Home Economics is a core subject that meets the goals of career education and hones career development competency to be prepared as future human resources. Finally, in order to strengthen the career development competency, a case study of Home Economics integrated career curriculum focusing on the association with curriculum-teaching & learning-evaluation was developed and proposed. Even though the developed case study of curriculum has not been proven yet in the class, this study is expected to contribute to the enlargement of career education of Home Economics in the career education intensive semester & grade system as fundamental data for integration of Home Economics and career education.

The 2015 revised national curriculum has been implemented to first year students in elementary school, and will be expanded to middle school and high school from next year, 2018 school year. As of this year, the ways of implementing the curriculum and supporting teachers to better implement the curriculum into their classrooms are crucial. This study explores the implications for building curriculum supporting and implementing system by investigating relevant systems in foreign countries, such as Australia and England. In order to achieve the purpose, this study conducts literature review and previous studies in regards to the curriculum implementing and supporting system, interviews with curriculum developers and teachers, and analyzes their web-sites of the two countries. The results shows that active communication is essential among curriculum developers and curriculum implementers including school teachers and other stake-holders, and this communication can be achieved by building systematic ways; second, professional development for teachers should be recommended by supporting integrated and systematic teaching-learning process; third, the principal agent for curriculum implementation, school teachers, should have the autonomy for implementing the curriculum. The detailed ways for realizing the three implications are suggested.

The purpose of this study is to examine the change and appropriateness of inquiry tendency in elementary science textbooks by national curriculum period by comparing previous researches that reported Romey's Involvement Index in the science textbook and other subject textbooks. The results of the study are as follows: First, for the text index (T), the value of science textbooks by curriculum tends to continue to decline overall. The value of science textbook based on the 3rd curriculum is judged to be extremely inquiry oriented and the value of the textbooks based on the 2007 and 2015 revised curriculum are the values judged as somewhat authoritative textbook and as a textbook at the appropriate level of inquiry, respectively. There is no significant difference compared to the T values of other subject textbooks since the 2007 revised curriculum; Second, the index of figures and diagrams in the text (FD) of science textbooks also continues to decline by curriculum periods. In particular, the FD value of science textbook of the 2015 revised period is judged to be a authoritative textbook, which is lower than the value of other subject textbooks; Third, in the case of the activity index (A), it gradually decreases from the third curriculum to the 2015 revised curriculum, but it is judged as textbooks suitable for inquiry. However, after the 7th curriculum, the value of A is generally lower than those of other subject textbooks; Fourth, for the index of the questions at the ends of chapters (Q), the value of Q is reported to be extremely limited compared to the aforementioned three indices(T, FD and A), which may be mainly due to differences in the composition of science textbooks by curriculum period.

In this study, the types of inquiry activities in the $5^{th}$ & $6^{th}$ grade science textbooks according to the 2015 revised science national curriculum were analyzed and compared according to grade level and science area. Science textbooks for elementary school $5^{th}$ & $6^{th}$ graders contain quite diverse types of inquiry activities, which are student-centered inquiry activities. There were comparatively higher proportions of inquiry types such as experiment & observation and simulation, but relatively lower of inquiry types of investigation-discourse & presentation, discussion, expression. Elementary science textbooks are expected to cultivate science key competencies for elementary school students. Considering the science area, the motion & energy, substances, earth & space, and integration areas had the most experiment & observation among activity types, while the life area had the most simulation activities. Even in some area of the 6th grade science textbook, there was little or no data interpretation, discussion, and simulation activities. In order to achieve the goal of elementary science education, science textbooks should be developed considering the revision of future elementary science curriculum.

This study analyzed reference data for the physics section in science guidebooks for the third-sixth grade in elementary schools, according to the 2015 revised curriculum. It analyzed the reference data by categorizing them in terms of subjects, objectives and presentation forms and the visual data used in the reference data by categorizing their types. The findings show that the ratio of the science knowledge type was highest (53.8%) among the subjects of reference data in guidebooks for the science section, followed by the application to real life, and then, supplementary inquiry experiments and activities. The ratios of other types such as advanced science, environment, scientists and science history were, however, less than 1%, so they need to be improved. The ratio of knowledge provision was highest (40.5%) among the objectives of reference data but the ratios of conceptual supplementation and deepening were similar in ratio. Meanwhile, While the expository type (88.4%) accounted for most of the present forms of reference data, and photographs and illustrations (93.6%) also accounted for most of visual data suggested with reference data. Thus more various types of presentation forms and the extension of visual data seemed to be needed. This study is expected to provide some suggestions for the meaningful use of reference data in guidebooks for teachers and for the development of science guidebooks for teachers in elementary schools.
