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.

In line with the emphasis on the importance of nature of science recently, this paper examines the degree and level at which the 2009-revised convergence science textbook, developed from the common science under the 7th curriculum in South Korea, reflected nature of science according to the development of curriculum. 'Nature of science' was classified according to scientific view - which represents scientists' view - and naive view - which represents general thinking and scientific error concepts. Also, 'Nature of science' was classified according to the explicit method and implicit method in terms of teaching method. The level of nature of science was defined using the four occasions of scientific view, naive view, explicit teaching and implicit teaching. In order to identify the components and level of nature of science reflected in the textbook, using the 10 items which refer to Lederman(2001)'s 7 definitions, NOSAT (Nature of Science Analyzing Tool) was developed and used. The results are that, since the educational curriculum is changed from common science under 7th curriculum to 2009-revised convergence science, the degree of reflection was rather a withdrawal. On parts of theories of 7th common science curriculum except research parts, it was difficult to find explicit nature of science. Also on 2009-revised curriculum, nature of science, which is seen on 2007 curriculum, disappeared. It is suggested that the future curriculum emphasizes the importance of nature of science, and bolster the reflection of nature of science according to the changing curriculum. Nature of science should not be expressed limitedly, but instead, should be more positively reflected, and the reflection method should be not implicit but explicit, allowing direct teaching. Towards that end, writers of the textbook should have an accurate understanding of nature of science. And, for the right teaching, teachers' capabilities are important and it is necessary to train teachers to understand and act for nature of science.

The purpose of this study is to derive implications for the development of the next home economics curriculum by comparing the 'function' and 'achievement standard' presented in the 14 subjects of the 2015 revised middle school common curriculum with the home economics curriculum. For this, keyword network analysis was conducted, and the results are as follows. First, in the 'function' of the 2015 revised middle school common curriculum, 'analysis, use, and expression' were found to be core function keywords with high Degree Centrality and the Eigenvector Centrality. Second, the functional keywords 'understanding, explanation, expression, analysis, and use' in the 'achievement standard' of the 2015 revised middle school common curriculum appeared with high frequency, and 'practice, problem-solving, search and reasoning' which are related to practical problem-solving ability appeared. It was confirmed that 'appreciation, solution and realization', which have relatively high Eigenvector Centrality, were core functional keywords used in the 'achievement standard'. Third, when the 'function' and 'achievement standard' of the 2015 revised middle school home economics curriculum were matched and compared, 7 out of 15 functions were not used in the statement of 'achievement standard', so the connection between 'function' and 'achievement standard' appeared to be insufficient. In addition, the diversity of functional keyword used in the 'achievement standard' was also found insufficient when compared to the middle school common curriculum. Therefore, this study propose strengthening the connectivity of 'function' and 'achievement standard' in the next home economics curriculum, using keywords such as 'analyze', 'express', 'compare', 'understand', 'interpret', 'explore', 'appreciate', and 'solve'.

This study was made in order to provide the groundwork for the revised 7th education curriculum of primary and secondary education's facility criterion. Throughout this study, in which we may accomodate the new education curriculum, we prepare the guide for the standard criterion of the school systems in order to reflect the flexibility of various dictinctive regional education conditions and school qualities considering the purpose of new standard criterion of school facilities. Below is the summary of the study. Regular classroom's standard size, which is the basic module for the scale of the educational institution, accomodates current standards. Number of students per class is aimed to fit the standard number of the level of OECD member countries' in order to prepare for the future ; that is, 30 students in primary, secondary and high school to be the standard number of student per class, depending on the district conditions and construction point of time. It is advised that the number of extracurricular classrooms, according to the standard criterion of subject and hour allotment, to reflect the regional and institution's distinctive qualities by indicating the number of hours and classrooms including decimal points. That is to be done so that the founder and the interested parties of the institution, along with the architect can put to practical use when planning and designing the institution.

The students in secondary schools have been taught calculus as an important subject in mathematics. The order of chapters-the limit of a sequence followed by limit of a function, and differentiation and integration- is because the limit of a function and the limit of a sequence are required as prerequisites of differentiation and integration. Specifically, the limit of a sequence is used to define definite integral as the limit of the Riemann Sum. However, many researchers identified that students had difficulty in understanding the concept of definite integral defined as the limit of the Riemann Sum. Consequently, they suggested alternative ways to introduce definite integral. Based on these researches, the definition of definite integral in the 2015-Revised Curriculum is not a concept of the limit of the Riemann Sum, which was the definition of definite integral in the previous curriculum, but "F(b)-F(a)" for an indefinite integral F(x) of a function f(x) and real numbers a and b. This change gives rise to differences among ways of introducing definite integral and explaining the relationship between definite integral and area in each textbook. As a result of this study, we have identified that there are a variety of ways of introducing definite integral in each textbook and that ways of explaining the relationship between definite integral and area are affected by ways of introducing definite integral. We expect that this change can reduce the difficulties students face when learning the concept of definite integral.

This study is to explore the directions for developing the lesson assessment of the math textbook in elementary school level, which is to embody the recent trends of math assessment and the emphases about assessment given in the revised 2009 math curriculum. To this end, we examined the recent trends of math assessment and the assessment framework of RME (Realistic Math Education) as the theoretical backgrounds. Also we analytically looked at the math-assessment emphases given in the revised 2009 math curriculum, and tried to establish the directions for developing the lesson assessment of the math textbook on the basis of the preceding studies. In addition to, we gave the math items in line with the established directions about lesson assessment. Finally we suggested the issues in relation with the math assessment in the elementary school level.

In this study, the analogies in the chemistry domain of middle school science textbooks developed under the 2007 revised National Curriculum were analyzed. A total of 235 analogies were found in 27 middle school science textbooks analysed, which means that one analogy per 10 pages was used on average. The number of analogies found in each textbook considerably varied depending on both publishing company and chemistry domain. Functional analogies, verbal and pictorial analogies, analogies with abstract target and concrete analog, enriched analogies, everyday contexts analogies, student-centered analogies, and analogies with low systematicity were frequently used. On presenting the analogies in the textbooks, the term analogy and description about the limitations of the analogies were rarely mentioned. In comparison with the analogies in the science textbooks developed under the 7th National Curriculum, the frequency of analogies per page was increased. There were positive changes in the aspects of representation, extent of mapping and artificiality. No differences, however, were found in the patterns of the other aspects.

The purpose of this study is to analyze the 'Pleasant Life' textbook in the elementary school focused on the perspective of ethnocentrism and cultural relativism. The first- and second-grade textbook 'Pleasant Life' of the revised 2007 national curriculum was made to serve build up sound body and mind through activities and play together with different products and life culture which is associated with multicultural education. But in the global world that is changing to the multicultural area, the textbook 'Pleasant Life' has a tendency to not to be satisfied this current needs. The analysis criterion is made up six elements: understanding culture, self-identify, human equality, conquest of prejudice and collaboration. The results of analysis on contents related to the multicultural education in the elementary 'Pleasant Life' textbook for the 1st and 2nd grade are follows. The first, in the plenty of images and pictures, there are not diverse races in the textbook. Yellow race naturally command an overwhelming majority in the textbook images and pictures. Second, the 'Pleasant Life' has a few multicultural contents and if teacher would not have will for teaching multicultural contents, he can't teach multicultural education. Third, 'Pleasant Life' textbook has overmuch ethnocentrism contents which is expressed traditional play and folk songs. These contents lead to exclusiveness for other culture to students. In conclusion, it is needed to grow concerns for multicultural education and the national curriculum should offer precise guidelines on the direction and standards of multicultural education.

In textbooks, illustrations are used to easily explain concepts and guide the exploration process. Therefore, the illustration should be presented accurately and easily. However, as a result of analyzing previous studies, it was confirmed that there was no research related to illustration analysis at all in the case of the elementary school 'software education' unit. Therefore, among the six practical textbooks developed according to the 2015 revised curriculum, the illustration of the 'software education' unit was analyzed in terms of type, function, and use, and provided guidelines for the adoption of textbooks, curriculum research, and next textbook development. As a result of analyzing six practical textbooks, all textbooks used more than one illustration per page, and the types of illustrations were used in the order of screen capture, picture, picture, table, illustration, illustrative function, and use.

This study compares the perspectives of experts and the public on the 2015 revised curriculum. To do this, research papers and newspaper articles were collected from October 2013 to May 2020. During this period, 1152 research papers and 692 newspaper articles were collected, and semantic network analysis was performed. As a result of the study, the educational expert group showed great interest in the core concept of the development of the revised curriculum focused on the abstract concept, while the public focused on the practical problems and consequences of the revision rather than the development of the revised curriculum itself. These results not only show the gap between the perspectives of the educational expert group and the public but also raise the need for effective communication to bridge the gap.
