This paper is a follow up study of [2]. In this paper we analyse the contents of middle school mathematics textbooks published in the 1st National Curriculum Period centered on the concept 'straight line' and discuss how they are different from contemporary mathematics textbooks in view of connectedness of contents, mathematical terms, textbook as a learning material vs. teaching material, relationship between contents of national curriculum and textbooks, and some topics related to direct proportion, function, method of equivalence as a method for solving simultaneous linear equations and so on. The results of our analysis and discussion suggest implications for reforming mathematics curriculum and developing mathematics textbooks.

On the basis of total page, the coverage rate of education of safety and health in textbooks of elementary school was approximately 10%. In middle school, the contents of safety education were addressed mainly in subject of chemistry below about 5% of coverage rate whereas the contents of health education appeared mainly in subject of athletics below about 15% of coverage rate. Similarly, the contents of safety education and health education in textbooks of high school were indicated mainly in the subjects of chemistry and athletics, showing below about 5% and 30% of coverage rate, respectively. In conclusion, the education level of safety and health in textbooks was generally lower compared to other contents. The coverage rate of safety education was relatively lower than health education, which implicates that extensive contents related to safety education are needed to be added to textbooks in order to establish preliminary attitude for preventing workplace accident.

21st century has begun as an age of green growth. Development paradigms disregarding environmental sustainability are being changed and henceforth, stronger efforts should be made to discover and utilize green values. With the importance of green values, rural amenity which is in the spotlight as a new channel to change the way people think about depressed agriculture and rural community could be the key to discover green values of rural area. This study is to emphasize rural amenity and to rectify prejudiced and distorted contents of agriculture and rural community in agricultural highschool textbooks. By doing this, students of agricultural highschool who will lead agriculture in the future will come to recognize the importance of agriculture and rural area and discovering it's values. This study was done through analysis and development of contents in 39 kinds of textbooks of Agricultural highschool. A content analysis was employed to examine to what extent the contents on agriculture and rural community were reflected in the textbooks of agriculture highschool. And 262 new education contents formulating positive and exact rural amenity concept were developed and 62 of them were included in textbooks.

The purposes of the study is to see as to how much of changes has occurred in the newly revised Home Economics Textbooks required by the 6th Curriculum as compared to those by the former the 5th Curriculum, and to seek future policy directions which can be improved even better, if any, for further revision. To implement this proposal, the study employs 8 different textbooks published in 1997 geared for the 6th Curriculum for data base. The components of the contents divides into two major parts. The first part falls into a category of holistic analysis of the textbooks, which gives a general perspective of the changes in the textbook revised. It includes those areas of changes in the total number of pages, cover page, illustrations, table of contents, appendices, unit cover, introductory remarks, summary and evaluation, etc. It also covers the information on authors of textbook. The latter part consists of several specific areas of major changes occurred in the textbooks for the 6th Curriculum. It covers such areas of changes in the composition of category and its weight, laboratory experiences, and illustrations and tables. To conclude the study, among many findings, two major points are of great importance to mention here. First, the new textbooks have adopted more of varieties in physical appearances and contents per se as to the older ones. And yet, there still found a weakness in numbers of authors participated to a full reflection of contents variety. In addition, the background of authors reflected on an unrealistic idealism which lacks the on-site information provided by the school teachers. Second, the strict regulations created by the Ministry of Education for developing textbook found restricting the authors creativity and thus contents variety of textbooks. Those restricting factors include letter type and size, coloring, paper quality, and volume size.

The contents of fraction division in textbooks are important because there were changes in situations and problem solving methods in textbooks according to the revision of the curriculum and the contents of textbooks affect students' learning directly. So, this study analyzed the achievement standards of the curriculum and formula types and situations, and the introduction process of non-standard and standard algorithms presented in Korean mathematics textbooks. The results are follows: there was little difference in the achievement standards of the curriculum, but there was a difference in the arrangement of contents by grades in textbooks. There was a difference in the types of formula according to textbooks. And the situation became more diverse; recent textbooks have changed to the direction of using the non-standard and the standard algorithm in parallel. In conclusion, I proposed categorizing rather than splitting the types of fraction division, the connection of non-standard and standard algorithm, and the need to prepare methods to pursue generalization and justification according to the common characteristics in the process of introducing standard algorithm.

The purpose of this study was to analyze the STS (science-technology-society) contents in chemistry chapters of middle school science textbooks standardized by 7th national curriculum, and to investigate chemistry teachers' perception of STS education. This study was based on 8 essential elements in STS education suggested by Yager and 9 activities in SATIS (science and technology in society). The questionnaire and interview were used to investigate chemistry teachers' perception. As a result of this study, the average value of the STS contents in chemistry chapters of 7 kinds of middle school science textbooks was 22.4%, and the STS contents were preponderated to essential elements of science application and local and community relevance. And STS contents showed that science 2 textbooks were the most of all and in order of science 1 textbooks and science 3 textbooks. As a result of analysis by activities in SATIS, most activities were practice activity, problem-solving and decision making, and structured discussion. Chemistry teachers' perceptions of STS education were following. There were many responses that STS education was necessary for educational efficiency. On the other hand STS education was unnecessary because there were few effective teaching-learning method related with STS education. From these results, middle school science textbooks have to be complemented because 2 essential elements of the STS contents were preponderated in the science textbooks. And the teaching-learning method connected with STS education will have to be developed for the efficiency of STS education.

The purpose of this study is to analyze the safety contents presented in high school science textbooks of the 2015 revised national science curriculum. For these, we found safety contents in the inquiries and appendices of 63 science textbooks: integrated science, science inquiry experiment, physics I, II, chemistry I, II, biology I, II, and earth science I, II. We analyzed these safety contents using six safety factors based on the seven standards for safety education. The main results are as follows: First, 81(46.0%) inquiries among 176 curriculum inquiries contain safety contents, and these contents are mainly found in chemistry textbooks, and the least in 'science inquiry experiment' textbooks. Second, safety contents are found the most in 'laboratory safety rule', followed by 'safety symbol' and 'usage of protection equipment'. Third, the safety contents of appendices are mainly in 'laboratory safety rule' and 'accident treatment'. Based on these results of this study, it is concluded that these textbooks have problems; that there is a big difference in describing safety contents in each textbook; that these safety contents are not presented in detail and that the educational effect is reduced. Furthermore, the safety symbol is not standardized. We also discussed ways to improve the safety contents of science textbooks.
