This research compares the subjects of "Integrated Science" and "Converged Science" in the 2015 Revised National Curriculum, through core concepts. The content priorities and levels of integration of each core concept were evaluated through an analytical framework, and visualized using two-dimensional visualization matrix of the content priorities and the levels of integration. The results show that "Integrated Science" had fewer core concepts, higher in priorities and slightly lower levels of integration than "Converged Science". This can be an evidence that "Integrated Science" is excellent in rigor and not so much inferior in relevance. And also, through visualization of analysis results, the characteristics of integrated subjects could easily be understood and compared.

The purpose of this study was to analyze chemistry textbooks and teachers' guidebooks from the perspective of 'Ignorance', one of the important features of model. This is because the emphasis is on developing modeling capabilities for students in the 2015 Revised Curriculum. For this, Arrhenius model and Brønsted-Lowry model were selected as acid and base models in neutralization reaction which are important contents in chemistry curriculum. The analysis criteria of this study were extracted by analyzing previous studies and four general chemistry textbooks dealing with 'Ignorance' related to acid and base neutralization reaction. Based on the analysis criteria, we analyzed nine chemistry I textbooks and teacher's guides and six chemistry II textbooks and teacher's guides of the 2015 revised curriculum. In addition, we analyzed contents of four chemistry I textbooks and teacher's guides and three chemistry II textbooks and teacher's guides in the 2009 revised curriculum for comparison according to revised curriculums. We analyzed the contents related to the concept of 'neutralization reaction', 'neutrality', 'quantitative relation of neutralization reaction', 'degree of ionization', and 'ionization constant'. Based on the results of this study, we proposed a way to present 'Ignorance' of the models in teachers' guidebooks that chemistry teachers can understand 'Ignorance' of model and teach modeling capabilities for students.

The goal of this study is to explore ways to restructure Convergence Elective Courses in science in preparation for the high school credit system, ahead of the 2022 revised science curriculum. This study started from the problem that the 2015 revised science curriculum has not guaranteed science subject choice for students with non-science/engineering career aptitudes. To this end, a survey was conducted by randomly sampling high schools across the country. A total of 1,738 students responded to the questionnaire of 3 science elective courses such as Science History, Life & Science, Convergence Science. In addition, in-depth interviews with 12 science teachers were conducted to examine the field operation of these three courses, which will be classified and revised as Convergence Elective subjects in the 2022 revised curriculum. According to the results of the study, high school students perceive these three courses as science literacy courses, and find these difficult to learn due to lack of personal interest, and difficulties in content itself. The reason students choose these three courses is mainly because they have aptitude for science, or these courses have connection with their desired career path. Teachers explained that students mainly choose Life & Science, and both teachers and students avoid Science History because the course content is difficult. Based on the research results, we suggested ways to restructure Convergence Electives for the 2022 revised curriculum including developing convergence electives composed of interdisciplinary convergence core concepts with high content accessibility, developing convergence electives with core concepts related to AI or advanced science, developing module-based courses, and supporting professional development of teachers who will teach interdisciplinary convergence electives.

The aims of this study were to analyze the cultural contents of 5th and 6th grade English textboooks written according to 2015 Revised National Curriculum, and to examine how much suggestions from preceding studies were reflected in the English textbooks. This study also aims to seek directions for desirable culture education in Elementary English textbooks. For this purpose, the culture content in 5th and 6th grade English textbooks were analyzed according to the types, materials, and background. The results show that the current English textbooks still has an imbalance by culture type, material, and background. Futhermore, the suggestions from previous studies were not fully reflected to new English textbooks. Therefore, cultural contents in textbooks should include more varied and balanced culture types, materials, and background in order for effective cultural education. Based on the findings, several suggestions are made for future research.

This study is focused on the examination of changes in textbooks of Home Economics in High school from 7^st to 2015 curriculum, especially the 'Food and Nutrition section. We investigated the content elements of the National Curriculum Guide, the changes in learning contents, and the number of pages of Food and Nutrition section. The key words were extracted and the connective relationships between words were visualized using a method of language network analysis through word cloud and Semantic Network Analysis. According to the results of the research, the portion of the Food and Nutrition section has been gradually decreased on the Technology·Home Economics, following the development of the curriculum. Through the whole curriculum, 'invitation', 'Korean food', 'baby·nutrition' are appeared as key words. The education contents of Food and Nutrition section from the 7^th to 2015 revised have been developed and advanced with the changes of social needs. However, the reduction of portion and insufficiency of content elements of Food and Nutrition section bring concerns toward the decline of the quality of education on dietary life.

The revised informatics is to be compulsory for middle school students from 2018 according to 2015 revised curriculum. The concept of abstraction in informatics curriculum has common features and differences compared with general abstraction, however there is a mix of concepts in the current informatics textbook. The abstraction of computational thinking needs to connect with automation, so it is difficult to teach correct concept of abstraction with these textbooks. Therefore, this research conducted to investigate several informatics textbooks that were developed by the revised curriculum and to analyze the concept and examples of abstraction. As a result, some textbooks have that there is a mix of concepts about general abstraction and no connection with automation. This research suggests clarified abstraction and educational examples for cultivating computational thinking to improve this situation. This result will be basic recourse for the reconstruction of abstraction lesson to improving computational thinking.

The purpose of this study is to analyze the achievement standards of the 2015 revision and 2022 revision of the science curriculum using the TIMSS 2023 science cognitive domain analysis framework. The subject of the study is the achievement standards for all elementary school areas in the 2015 and 2022 revised science curriculum. Three field teachers and one elementary science education expert who majored in elementary science education participated in the research analysis. The results of this study are as follows. First, in the 2022 revised movement and energy field, the ratio of the 'knowing' area was about 16% higher than the 2015 revision, and the ratio of the 'reasoning' area also increased by about 5.8%. Second, in the material field, the proportion of TIMSS 2023 cognitive domains was in the order of 'knowing', 'applying', and 'reasoning' regardless of grade group and curriculum revision period. Third, in the field of life sciences, the proportion of TIMSS 2023 cognitive domains differed depending on grade group and curriculum revision period. Fourth, in the Earth and Space field of the 2022 revision, similar to the other three fields, the proportion of the 'Knowing' field increased and while the 'Applying' field decreased. However, in the 2022 revision, the 'reasoning' area in all three other fields increased, but decreased only in the earth and space fields. Fifth, the 2015 revised integrated unit and the 2022 revised science and society field only covered the elements of 'recognizing' and 'presenting examples' in the 'knowing' area, 'making relationships' and 'explaining' in the 'applying' area and 'Synthesize' in the 'reasoning' area. In the 2022 revised elementary school science field, the proportion of the 'knowing' section was 52.5%, the proportion of the 'applying' section was 33.8%, and the proportion of the 'reasoning' section was 13.7%. In conclusion, in the 2022 revised elementary science achievement standards, the ratio of the 'applying' and 'reasoning' areas was low because the reliance on the 'knowing' area was too high.

This study aims to investigate the presentation of the Nature of Science (NOS) in integrated science textbooks of the 2015 revised curriculum. The five integrated science textbooks published by the revised 2015 curriculum were analyzed with the conceptual framework of the four themes of the Nature of Science (NOS) (Lee, 2013) based on scientific literacy. The four themes of the NOS are 1. nature of scientific knowledge (theme I), 2. nature of scientific inquiry (theme II), 3. nature of scientific thinking (theme III), and 4. nature of interactions among science, technology, and society. The reliability of the textbooks analysis was measured between two coders by the Cohen's kappa and resulted in between 0,83 and 0,96, which means the results of analysis was consistent and reliable. The findings were as follows. First, overall theme II, nature of scientific inquiry emphasized on the integrated science textbooks of the 2015 revised curriculum by devoting the contents over 40 % in the all five publishing companies' textbooks. Second, while the theme II, nature of scientific inquiry was emphasized on the textbooks regardless of the publishing companies, other themes of the NOS were emphasized in different portions by the publishing companies. Thus, the focus among other three themes of the NOS was presented differently by the publishing companies except that in theme II, nature of scientific inquiry was most emphasized on integrated science textbooks. Third, the presentation of the NOS was identified similarly across the topics of integrated science textbooks except on topic 4. Environment and Energy. The theme IV, nature of interactions among science, technology, and society was emphasized reasonably only in the topic of Environment and Energy of the textbooks. Finally, the presentation of the NOS in the integrated science textbooks of the 2015 revised curriculum were more balanced among the four themes of the NOS with focus on the scientific inquiry compared to the previous curriculum textbooks.

The 2015 national revised curriculum was notified officially the last year. The intent and direction of the revision caused more or less change for mathematical contents to be taught and is expected to cause a considerable change in math class. In the level of elementary school mathematics, it turned that several contents were deleted or moved to the upper grades because the revision focused especially both on reducing students' burden of learning and on fostering the mathematical key competences. This study aims to examine the relevance of the change through investigation of the national curriculums for elementary school mathematics since 1946. The mathematical contents to be analyzed in this study were mixed calculation of natural numbers, mixed calculation of fractions and decimal fractions, position and direction of objects, are/hectare and ton, the range of numbers and estimating, surface and volume of cylinders, pattern and correspondence, and direct/inverse proportionality, which were changed in any aspect relative to 2009 national revised curriculum. Based on the results of these analyses, the discussion will provide some suggestions for setting the direction of elementary mathematics curriculum.
