This study looked at the deviation of each textbook, focusing on the detailed learning content related to the quadratic curve properties contained in high school geometry textbooks. Rather than criticizing the diversity of content elements covered in high school geometry textbooks and suggesting alternatives, it focused on analyzing the actual conditions of content element diversity. The curriculum specifies that the practical application of the quadratic curve should be emphasized so that student could recognize the usefulness and value. However, as a result of the analysis, it was confirmed that the purpose of the curriculum and the structure of the textbook did not match somewhat, the deviation of content elements for each textbook was quite large. In terms of acknowledging the diversity of teaching and learning, the diversity of each textbook on the methods of the introduction and the natures related to the quadratic curve can be fully recognized. But in our educational reality, which is aiming for the university entrance examination system through national evaluation such as CSAT, the results are too sensitive in society as a whole, so the diversity of expressions in mathematics textbooks is sometimes interpreted as a disadvantage of evaluation. It is time to reconsider the composition of textbooks that recognizes the diversity of content elements in textbook teaching and learning and at the same time reflects the aspect of equality in evaluation.

This paper analyzes user preferences on the basic structure of digital textbook contents based on the PDF and HTML formats. This was conducted by analysing the data from an online survey on user preferences for the representative structures of the PDF- and HTML-based digital textbook contents that are currently used on the Web. Results show that in the PDF format, the structure with TOC(Table Of Contents) links on the left screen and the main content on the right was most preferred by 82% of the respondents. In terms of the viewing method, the one that presents one page of the textbook fitted to the width of the computer screen in a single-page view was regarded as the best. Similarly, in the HTML format, the structure with TOC links on the left frame and the main content on the right using 2-frames was revealed as the most preferred by 84% of the respondents. However, the structures of the PDF- and HTML-based digital textbook contents employed by most existing Web sites go against the users' preferences. Accordingly, for digital textbook development in the future, user preferences must be considered to allow students to read the contents more easily and conveniently.

Mathematical tasks in general introduce and deal with real-life situations, and they derive to students' thinking fluently in solving the given tasks. The tasks might be considered as an important and significant factor to lead a successful mathematical teaching and learning situation. MiC Textbook is a representative one showing such good examples and tasks. This study explores concretely and in detail the cognitive demand level of mathematical tasks, by the subject of MiC Textbook. To accomplish this, this study is to reconstruct more elaborately the analysis framework developed by Hwang and Park in 2013. The framework basically was set up utilizing 'the cognitive demand level' suggested by Stein, et, al. The cognitive demand level is divided into two levels such as low level and high level. The low level is comprized of two elements such as Memorization Tasks(MT), Procedures Without Connections Tasks(PNCT), and high level is Procedures With Connections Tasks(PWCT), and Doing Mathematics Tasks(DMT). This study deals with the tasks on the area of 'data analysis and statistics' in MiC 1, 2, 3 level Textbook. As a result, mathematical tasks of MiC Textbook led learners to deal with and understand mathematical content for themselves, and furthermore to do leading roles for checking and reinforcing the content. Also, mathematical tasks of MiC Textbook are comprized of the tasks suitable to enhance mathematical thinking ability through communication. In addition, mathematical tasks of MiC Textbook tend to offer more learning opportunity to learners' themselves while the level of MiC Textbook is going up.

The purpose of this study was to find out how much home economics(HE) textbook was focused on what kind of factors in career education, by analyzing the HE textbooks from the 7th grade(1st grade of the middle school) to the 10th grade(1st grade of high school), which were developed by applying the 7th educational process. 12 textbooks which were published by three publishers were randomly selected by grade. This study used the instrument developed by Korea Research Institute for Vacational Education & Training(2001) as an analysis frame, along with a content analysis system. The results of this study were as follows. The publishers of HE textbook stressed similar points in each section of career education, evenly reflecting the objectives and contents of career education. Three kinds of publishers also placed the same weight on the factors of career education in each unit, and suggested the contents related to career education in the whole units. HE textbook was designed to lead learners to understand self and have interest in varied occupations. Additionally, it provided the learners with a chance to consider their career and occupation by means of detailed job information, and its contents including learning of occupational ability for job selection were useful to plan and prepare for career. Accordingly, as HE textbook is most effective to promote connection between work and learning and contains proper factors of career guidance, it is one of the most appropriate textbooks to deal with career education.

In this paper, we examine the different viewpoints of teachers and undergraduates on middle school informatics textbook. For this research, a survey is conducted on middle school informatics teachers and undergraduates who are preparing the state examination for informatics-computer teachers. Items of the survey were chosen to investigate the level of completion on the contents and structure of the textbook and to examine overall satisfaction with the textbook. Seven items concerning the level of completion are based on national textbook authorization criteria. A t-test was performed to analyze meaningful difference in perception of textbook between the teacher and student groups. The result shows there is meaningful difference on two items which are 'compliance with informatics curriculum' and 'content selection and organization'.

The purpose of the study is to compare and analyze the elementary science textbooks' contents between the United States(Science Horizons) and Korea for teaching the Returnee students. The analyzed contents are the name of chapters, the number of chapters, the page amounts of chapters, the structure of chapters and the studying time of chapters. The results of this study are : 1. Korean science textbook's number is 20. 'Science Horizons' has 6. Korean science textbook's total number of chapter is 58, 'Science Horizons' is 75. Korean science textbook's total number of page is 1,60.3, 'Science Horizons' is 2,106. So 'Science Horizons' has more number of chapter and page than Korean textbooks. 2.

Environmental education in Korea has been emphasized since the Fourth National Curriculum. The Environment curriculum became independent as 'Environment' for middle school and 'Environmental Science' for high school were set as independent subjects upon the Sixth National Curriculum of Korea. And the Enviroment Textbook for middle school was published by the Ministry of Education of Korea. The purpose of this study is to analyze environment textbook for middle school focusing on the organization, the format, questions and illustrations. It was expected that the results of this study could be used by Environment textbook developers. According to the analysis of 'Environment',on the organization, the textbook was consisted of 219 pages and 22 units. A unit was consisted of many subunits and activities. On the content of the textbook, the objectives of subunits stressed more on explanation form than on exemplification form. On the questions, most of them were in <activities> and the objectives of questions stressed on the presentation of the contents. The specific aspect referring results, cause, and judgement, etc. were vary rarely checked. The questions seemed as good, because questions were mostly pertinent to the what to ask, and had a good connection to the main text. By the analysis of illustration, illustrations were mostly functioned as supportive and rarely as decorative, Most of them were photographs and printed all in black-and-white pictures.

In this study, the content and level of the elements of Computational Thinking in the Software Education area of elementary practical textbooks were analyzed, and also the computing ratio for each textbook learning activity was analyzed. The elements of Computational Thinking were defined based on the components and definitions of Computational Thinking skills suggested by the Ministry of Education. The contents of Software Education area in practical arts textbooks published by six publishers were analyzed. As a result of analyzing the elements of Computational Thinking for each textbook according to the achievement criteria, there was a difference in whether sub-elements of Computational Thinking were included for each textbook. Second, as a result of analyzing the level of Computing of learning content, the proportion of textbooks presenting Abstract activities connected to Computing was relatively low. When the curriculum is reorganized or the textbook is revised in the future, it is necessary to complement the elements of Computational Thinking in a balanced way, and to include general Abstraction activities and Abstraction activities that can lead to Automation.

This research analyzed the contents of the elementary and middle school home economics textbooks within the 7th Curriculum from two theoretical Perspectives: structural functionalism and healthy family. A quantitative and in-depth content analysis was carried out with the five elements of family structure, family role, family relation, communication, dating and pregnancy. A healthy family Perspective was found in relation to the elements of family type and family role from the in-depth analysis of the elementary school practical arts textbook. In the middle school textbooks, the five elements reflected a strong structural-functionalist tendency. In both levels, the quantitative content analysis indicated that a structural-functionalist viewpoint was prevalent in the graphical components of the textbooks, including pictures, diagrams and graphs.
