In order to prepare for changes in future society, cross-curricular learning is emphasized, and the need to link cross-curricular learning topics and subjects is increasing. However, there are few studies on how to deal with cross-curricular learning in mathematics education. This study analyzed the contents and methods of cross-curricular learning topics in subject-specific curriculum and mathematics textbooks. As a result of the study, the curriculum can be categorized into four types according to the variety of cross-curricular learning topics applied and the presence or absence of a main cross-curricular learning topic, and the mathematics curriculum belongs to the type where some cross-curricular learning topics are dealt with passively and there is no main topic. On the other hand, the analysis of 10 math textbooks for grades 5 and 6 according to the 2015 revised curriculum showed that, unlike the curriculum, various cross-curricular learning topics were applied in the textbooks, mainly environment and sustainable development education, safety and health education, career education, character education, and economic and financial education. In addition, in mathematics textbooks, cross-curricular learning topics appeared in various types such as materials, questions, explanations, illustrations, and in many cases, they appeared mainly as materials or illustrations. Based on these findings, implications were explored and suggested on how to integrate and apply cross-curricular learning topics in mathematics.

In this thesis, newly distributed informatics-1 textbook is analyzed according to the curriculum for middle school revised in 2007 and, as a result, a questionnaire is conducted to find solutions for early adoption of informatics-1 textbooks. The sample of this survey was limited to Kyungi province-based middle school teachers on Informatics-1. Items of the survey were chosen to explore the degree of satisfaction of teachers on the informatics-1 textbook and to discover contents requiring further necessary revision. Out of seven items concerning the satisfaction of the textbook, the item with the most positive responses was 'the consistency with the curriculum' with 95%. Also, the item with the most negative responses was 'the adequacy of contents and their organization' with 13%. In conclusion, we, based on the results from the questionnaire, proposed the introduction of various lecture materials and the training of teachers to learn new teaching methods.

We extracted core terms by constructing scientific item networks from textbooks, analyzing their structures, and investigating the connected information and their relationships. For this research, we chose three high-school textbooks from different publishers for each three subjects, i.e, Science, Biology I and Biology II, to construct networks by linking scientific items in each sentence, where used items were regarded as nodes. Scientific item networks from all textbooks showed scare-free character. When core networks were established by applying k-core algorithm which is one of generally used methods for removing lesser weighted nodes and links from complex network, they showed the modular structure. Science textbooks formed four main modules of physics, chemistry, biology and earth science, while Biology I and Biology II textbooks revealed core networks composed of more detailed specific items in each field. These findings demonstrate the structural characteristics of networks in textbooks, and suggest core scientific items helpful for students' understanding of concept in Science and Biology.

In this paper, We analyse the contents of the national mathematical curriculum, the handbook of the curriculum, and elementary school mathematics textbook for the elementary school grade 1-2 focusing on 'number sense'. At first, we identify the meaning and the elements of number sense through analysing studies which are related to number sense. Number sense includes understanding the meaning of number, operation, and estimation, and the ability of applying numbers, operation and estimation on the context. Number sense consists of the elements of the contents and the elements of the processes. Secondly, with the elements of number sense which we have identified, we analyse the contents of the national mathematical curriculum, the handbook of the curriculum, and elementary school mathematics textbooks, and then criticize the contents. We find some problems as a result of the analysis : the range of number sense is unclear, the word 'number sense' is not used consistently, the elements used are limited, and the contents of the textbook are materialized inconsistently and poorly.

With the introduction of AI digital textbooks, interest in the use of technology tools in mathematics education is increasing. Technology tools have the advantage of visualizing mathematical concepts and discovering mathematical principles through experimentation and inquiry. The 2015 revised mathematics curriculum in Korea already mentions the use of technology tools, and accordingly, various teaching and learning activities using technology tools are presented in mathematics textbooks. However, there is still a lack of systematic analysis on the types and utilization methods of technology tools presented in textbooks. Therefore, this study analyzed the current status of the use of technology tools presented in high school mathematics textbooks based on the 2015 revised curriculum. To this end, the types of technology tools presented in mathematics textbooks were categorized, and the utilization ratio of each category was investigated. In addition, the utilization patterns of technology tools were analyzed by subject and content area, and the utilization ratio of technology tools according to the type of teaching and learning activities was examined. The results showed that technology tools were used in various types and ratios according to the subject and content area. In particular, technology tools in the symbol-manipulation graphing software category accounted for 58% of the total usage cases, showing the highest proportion. By subject, the use of symbol-manipulation graphing software was prominent in subjects dealing with the analysis area, while the use of dynamic geometry software was relatively high in the geometry area. In terms of teaching and learning activity types, the utilization ratio of auxiliary tool type (49%) and intended inquiry induction type (37%) was high. The results of this study show that technology tools play various roles in mathematics textbooks and provide useful implications for improving mathematics teaching and learning methods using technology tools in the future. Furthermore, it can contribute to the establishment of educational policies related to AI digital textbooks and the development of teacher training programs.

Both Earth science II and Korean geography textbooks emphasize the importance of content related to 'geology of the Korean Peninsula'. This study aimed to analyze the differences in the content related to the 'geology of the Korean Peninsula' presented in the textbooks, and to find out whether these differences are consistent with the latest scientific knowledge in any inconsistencies are found. For this purpose, seven textbooks (four Earth science II and three Korean geography) published under the 2015 revised curriculum were selected as the subject of analysis, and the difference in the description of the tectonic provinces of the Korean Peninsula, geologic time scale, and explanatory texts of geological characteristics between Earth science II and Korean geography textbooks were compared. As a result of the analysis, there are some cases of inconsistencies between Earth science II and Korean geography textbooks in terms of terminologies, names, and distribution ranges related to the tectonic provinces of the Korean Peninsula. The Korean geography textbooks had inconsistencies in the geochronologic data of the rocks as they cited outdated data. In addition, inconsistencies were found in the explanatory texts describing the 'distribution of rocks on the Korean Peninsula', 'characteristics of the Pyeongan Supergroup', and 'great hiatus of the Paleozoic Era'. Both Earth science and Geography have many concepts in common, therefore, effort is needed to minimize the differences in content. It is important to select the content appropriately which should reflect the latest scientific knowledge and presents the concepts consistently.

The purpose of this study is to suggest a pedagogic direction of home economics education that can form body image which organize self-concept of adolescents positively. To achieve this purpose, the study suggested a body image formation model of adolescents that can be applied to home economics education, and based on this formation model, analyzed contents on body image of current 12 textbooks of home economics education. The main results of this study are summarized as follows: First, to analyze textbook through body image formation model of adolescents, educational contents about body image were categorized into 4 constructs with 8 sub-categories. Second, we found the current textbooks about the child and family life field, food and dietary life field, and clothing life, are handling topics regarding body image formation model of adolescents, such as concepts and components of body image and antecedents and outcomes of body image. We conclude that although the current textbooks handles contents on body image of adolescents, those contents are sporadically presented across the three fields without an integrated perspective. Home Economics, as an entity of educating adolescents' self-esteem through daily life activities, needs to have a topic-oriented approach in developing a curriculum.

This study is aimed to compare the area of geometry of elementary mathematics textbooks in korea and china. Through this study, we would like to suggest some guidelines in order to develop geometric curriculum and textbooks in korea and to search for more efficient methods of learning mathematics. For this, we have looked through the general characteristics of geometry domain in mathematics curriculums and the textbooks in korea and china. Furthermore, we have found the similarities and differences while comparing specific contents in the two countries. The followings are the conclusions of this study. First, The mathematics curriculum in korea is divided into 'figure' domain, but the one in china is divided into 'space and figure' domain, which deals with figure and measurement. And china constructs the contents of the basic figure as a whole unit. Second, korea gives clear learning aims about contents whereas china gives learning activities. Lastly, when starting teaching a plain figure, korea focuses on checking and finding definitions and characters through fundamental figures. However, china focuses on figuring out components and the relations among them throughout various plain figure activities.

This study analyzed the aspect of occupational contents shown in total 24 types of Technology & Home Economics (1). (2) textbooks for middle school in accordance with the 2009 revised curriculum. Analyzing the type of occupation shown in textbooks based on the Korean Standard Classification of Occupations(hierarchical classification), the frequency(ratio), and the aspect of occupational contents in each unit of textbooks and each data type, this study provided basic data to be able to understand diverse aspects of occupational contents. In the results of study, in case of Technology & Home Economics textbooks for middle school, the large area of 'home life' presented occupational contents in the relatively high ratio than the 'world of technology' while the frequency(ratio) of occupational contents was very much different in each publisher, large area, and unit. The occupation name presented in textbooks provided very limited information in the level of 5.27% of occupations presented in the Korea Dictionary of Occupations. Especially, providing occupational information concentrated in professionals & relevant practiceans in the type of the Korean Standard Classification of Occupations(hierarchical classification), it was limited to provide opportunities to learn the diversity related to occupation. Based on such results of study, on top of introducing diverse occupational contents to make students cherish all the occupations, it would be also necessary to seek for institutional measures related to textbook development/career education, so that they could explore career by considering their aptitude and interest.
