This study was to compare 'experiment' presentation types of middle school science textbooks of Korea, Japan, and China and to draw some implication for the improvement of Korean science textbooks. It analyzed the experiments from the unit 'Light' of science textbooks which is common content in all three different science textbooks. The researchers analyzed the experiments with two questions. First, how is the experiment organized? Second, what role does each element of the experiment is playing in the experiment setting? The findings of international comparative analysis of experiment presentation types of middle school science textbooks of three countries were as follows. First, the Korean and Chinese textbooks tended to present the experiments without enough information for the experimental process and method, whereas the Japanese textbook tended to present the experiment with detailed information for the experimental method and process. Second, whereas the Korean and Chinese textbooks tended to have a loosened relationship among pre-experimental content, experiment, after-experiment content, the Japanese textbook tended to have an organic relationship among pre-experimental content, experiment, after-experiment content.

This study was conducted as a part of the project to evaluate the quality of mathematics instruction in the national curriculum system. The purpose of this study is to measure the consistency between teaching goals of mathematics curriculum, contents presentation of textbooks, and testing including adequacy of each element in mathematics instruction for 8th grade. To do this, we used MIQP (instructional quality profile for Mathematics) developed basing on the instructional quality profile (IQP) in the previous research of the project. First, the quality of textbooks' content presentation for 8th grade was found that the desirable levels in number and operation area and geometric area was relatively less compared to other areas, but it was generally good. Second, it was found that the quality of mathematics testing for 8th grade was good in terms of consistency with the curriculum's teaching goals, consistency with the content presentation of textbooks, and adequacy of testing. However, regional differences in the quality of testing showed that there were some deficiencies in regions outside the metropolitan.

This study is to analyze literacy textbooks for adult learners developed by adult literacy education institutes. In the study, six different kinds of literacy textbooks are collected and analyzed on the basis of five evaluation criteria.: unit organization, presentation way of Hangeul, type of content, level of content, and degree of subject integration. The results of literacy textbook analysis are as follows. First, literacy textbooks carry different forms of unit organization in different textbooks. Most textbooks are composed of lessons, without a hierarchical organization of lessons, whereas some textbooks carry a hierarchical structure of 'unit + lessons'. Second, Hangeul is mostly presented in the form of reading and writing and literacy textbooks tend to present Hangeul as constructing letter through combining vowels and consonants rather than as whole language. Third, literacy textbooks contain life-adjustment situations which would help adult learners to lead everyday lives more efficiently. Fourth, literacy textbooks carry different levels of educational content, ranging from 'basic Hangeul' through 'expanded content' to high level of Hangeul writing. Fifth, literacy textbooks appear to integrate educational content from different subjects in order to provide more relevant content for adult learners.

The objective of this study is to promote alternative plans on the prejudiced and distorted contents in school textbooks in the aspect of multi-functionality of agriculture and rural community. This was done through analysis of contents in 47 kinds of textbooks in science (8 of elementary school, 27 of middle school and 12 of high school). This will lead to promote understanding about the multi-functionality and form the proper value system related to agriculture and rural community for children and juveniles using textbooks. A content analysis was employed to examine to what extent the contents on agriculture and rural community were reflected in the textbooks for elementary school, middle school and high school. The content analysis was done in three categories, including presentation form, application method and function view. The followings are results of contents analysis in textbooks. The most frequently used presentation forms related to agriculture and rural community was figures and tables. In analysis of application methods, this research found that the contents related to agriculture and rural community were used to explain scientific facts and phenomena. In the function view, maintenance of local societies was most frequent among the various multi-functionalities in elementary and middle school, and food security in high school. Based on the results of content analysis, findings and recommendations in textbooks for elementary, middle and high school have been drawn, and several examples for contents development to be included in the textbooks were listed.

The national reform document, Science for All Americans (AAAS, 1990), and the Next Generation Science Standards (NRC, 2012) emphasize the importance of the nature of science in guiding science educators in accurately portraying science to students. Therefore, it is important that textbook materials convey an accurate conception of the nature of science. This study employs content analysis to examine the content of textbooks in US and Korea elementary science textbooks with regard to the four aspects of the nature of science: (a) nature of scientific knowledge; (b) nature of scientific inquiry; (c) nature of scientific thinking; and (d) nature of interactions among science, technology, and society (Chiappetta, Fillman, & Sethna, 2004). Intercoder reliability was determined by calculating Cohen's kappa (Cohen, 1960). Findings show that while US elementary science textbooks are not balanced in presenting the four aspects of the nature of science regardless of the publishing companies, the presentation of the nature of science in Korean elementary science textbooks have better balanced treatment of the four themes across the grade levels. On the other hand, both US and Korean elementary science textbooks are attempting to convey an idea of what science is by emphasizing scientific knowledge and investigation.

The purpose of this study was to examine whether or not they have been revised corresponding to the purpose of revision by making a comparative analysis of the content and illustration in the 6th and 7th primary science textbooks. The analysis of content was composed of knowledge, inquiry process and attitude. The analysis of illustrations was composed of the kinds of illustrations and the role of illustrations. The findings of this research were as follows: First, as a result of content analysis of the primary science textbooks in the 6th and the 7th national curriculum, the ratio of inquiry process showed the highest frequency, next knowledge and lastly scientific attitude. And the 7th textbooks are greatly emphasized knowledge and science attitude. Second, as a results of the illustration analysis are as follows: There are conspicuous differences in that the illustration number of the 7th science textbooks Is about twice the illustration number of the 6th science textbooks and next, they place more weights on pictures and comics hard to discovery in the 6th science textbooks. Therefore, they have tried to induce the interests of students and heighten their understanding by supplementing the role of illustration presented as picture-centered and increasing its number presented as picture. In the results, although they have improved the problems of the 6th national curriculum a lot through the innovation including the interest induction of pupils through comics, the development of its content presentation method, the gradual change of subject number and the cultivation of curriculum according to the level of enrichment and supplementing types, the 7th science textbooks have fallen short of 6.3%, not around 30% in terms of the reduction in the 7th national curriculum. Accordingly, the 7th science textbooks also can be pointed out to have the problems of too much amount of studying compared to the time per week like the 6th science textbooks.

The aim of this study was to subdivide and present the units and the standards of knowledge integration in creating the students' integrated knowledge from content knowledge in college writing classes. For these, it analyzed three typical writing textbooks being used in colleges and examined the ways of presentation on forming integrated knowledge by text qualitative analysis methods. The analysis procedure and the presentation followed Creswell's spiral analysis model It is a method model which repeats the procedure from material collection and analysis to presentation circularly. This examination illustrates three dimensions of the units in forming content knowledge. Also, it suggested those should be all treated for the more systematic education: the units of the whole text, the paragraphs, and the sentences. In the next chapter, the standards and contents of knowledge integration were suggested in each process. For the process of knowledge selection, the suitability and the contradictoriness between the text materials and author's thesis were proposed as the standards and contents. For the process of organization and integration, the corresponsive integration, contradictive integration, background integration, synthetic integration were suggested. Finally the procedure knowledge such as correct expression and spelling, source indication were shown for the process of expression and citation. Furthermore, it showed, in terms of expression, the process of paraphrasing frequently practiced in writing textbooks needs to be exercised in the three dimensions including summarization, connection, and interpretation(or transformation). This result, however, calls for the further study about the subdividing processes to enhance the adequateness to writing textbooks in the level of universities and for a more refined syllabus on the systematic knowledge integration. Accordingly, it suggested the tasks mentioned above for further study.

Understanding the nature of science (NOS) has been a major component of scientific literacy and an important learning goal in science education (American Association for the Advancement of Science, 1990, 1993; Millar & Osborne, 1998; National Research Council, 1996, 2013). To achieve this goal, it is necessary to include appropriate views of the nature of science in science curriculum such as a textbook. The aim of this study was to conduct a content analysis of the elementary science textbooks to examine the presentation of the nature of science (NOS) using the four themes of scientific literacy, which are (1) nature of scientific knowledge, (2) nature of scientific inquiry, (3) nature of scientific thinking, and (4) nature of interactions among science, technology, and society (STS). Findings show while $3^{rd}$ and $4^{th}$ grade levels of science textbooks heavily emphasize on the Theme I, nature of scientific knowledge and the Theme II, the nature of scientific inquiry, the upper grade levels such as $5^{th}$ and $6^{th}$ grades of science textbooks are well balanced with the four themes of the nature of science. In addition, most of elementary science textbooks little focus on the Theme IV, nature of interactions among science, technology, and society (STS) among the four themes of the nature of science. It might be a shortcoming because the understanding the nature of interacions among science, technology and society (STS) is one of the key components in order for students to be a scientific literate person.

The purposes of this study are to help the authorized textbooks on home economics be selected and used effectively, to provide basic data that are needed to improve the quality of home economics textbooks, and to suggest a next curriculum on home economics. In the study, eight high school home economics textbooks for "6th Curriculum developed by Ministrv of Education and Human Resources Development"were used for the analysis. The results are summarized as follows: there were wide differences in degrees of diversity and accomplishment in the contents of textbooks. In comparison, it was unfolded that three areas, "family", "home resource management" and "consumer" ,occupied much larger portions than other areas. About 81 percent of the authors of home economics textbooks were professors. A contents analysis on the clothing area showed that every textbook includes costume culture, clothing materials, clothing maintenance, and clothing construction. The presentation coverages and relative difficulties of textbooks were, however, diverse. It is somewhat noticeable that, while fewer professors majoring in clothing construction participated in writing, generally more pages were allocated to clothing construction than other areas. While presentations on anthropometrics method, construction theory, draft theory, usage of sewing machine and fitting theory were insufficient most textbooks were dealing with drafting of basic slopers and sewing procedure, etc. Making-up techniques on the apparels items such as Korean traditional men's pants, pajamas, shirt vest skirt, pants, apron and Korean pouch were handled closely in each textbook.

This study examines the content of vectors and matrices in Artificial Intelligence Mathematics textbooks (AIMTs) from the 2015 revised mathematics curriculum. We analyzed the implementation of foundational mathematical concepts, specifically definitions and related sub-concepts of vectors and matrices, in these textbooks, given their importance for understanding AI. The findings reveal significant variations in the presentation of vector-related concepts, definitions, sub-concepts, and levels of contextual information and descriptions such as vector size, distance between vectors, and mathematical interpretation. While there are few discrepancies in the presentation of fundamental matrix concepts, differences emerge in the subtypes of matrices used and the matrix operations applied in image data processing across textbooks. There is also variation in how textbooks emphasize the interconnectedness of mathematics for explaining vector-related concepts versus the textbooks place more emphasis on AI-related knowledge than on mathematical concepts and principles. The implications for future curriculum development and textbook design are discussed, providing insights into improving AI mathematics education.
