The purpose of this study was to analyze the inquiry elements and inquiry activity of the inquiry area in chemistry I textbooks authorized by 7th curriculum. It was to confirm suitable reflection of the 7th science curriculum and to find educational suggestions of inquiry learning. It was found that the basic inquiry elements except measuring and classifying were well reflected on the textbooks. However, only several integrated inquiry elements and the inquiry activities were well reflected on the same textbooks. For the integrated inquiry elements, interpreting data was shown as the tower above the rest inquiry elements. In the analysis of inquiry activity, the numbers of experiment is placed almost half of all inquiry activities. The sum of two numbers of investigation and discussion is similar ratio to experiment but field trip and project are rarely or low ratio. As the integrated inquiry elements and inquiry activities were not balanced for various inquiry learning. It is suggested that learners be educated with complementary of these aspects in inquiry learning.

The purpose of this study is to analyze the concerns and difficulties encountered by authors involved in the development of integrated science textbooks. Specifically, it focuses on their experiences with understanding and implementing the 2022 revised science curriculum. We collected 89 opinions from textbook authors and categorized them into several key areas: understanding the terminology and descriptors provided in the curriculum, structuring learning content, inquiries and activities, and the depth and scope of learning content. The analysis revealed that the most difficulty encountered by the textbook authors was in defining the level and scope of learning content. Many also expressed concerns and difficulties related to the ambiguity of terms and predicates. In terms of the composition of learning content, difficulties were identified in concerning the repetitive descriptions of achievement standards and the discrepancy between the arrangement of achievement standards and the flow of learning. Regarding inquiries and activities, there were experiments presented that were difficult to experience or actually implement, along with limitations in activity composition due to the need to optimize learning volume. Given the importance of high-quality textbooks for effective science education at the national level, it is crucial to establish effective communication channels between curriculum developers and textbook authors. Additionally, a robust support system for textbook development should be established.

This study aims to find meaningful implications for the development of Korean elementary school math education courses and textbooks by comparing and analyzing the number and arithmetic areas of Korean and Canadian math textbooks in fifth and sixth grades. To this end, the textbook composition system of Korean and Canadian elementary schools was compared and analyzed, and the number and timing of introduction of math textbooks and math textbooks by grade, and the number in fifth and sixth grade and the learning contents of math textbooks were compared and analyzed. The following conclusions were obtained from this study: First, it is necessary to organize a textbook that can solve the problem in an integrated way by introducing the learned mathematical concepts and computations naturally in the context of problems closely related to real life, regardless of the type of private calculation or mathematics area. Second, it is necessary to organize questions using materials such as real photography and mathematics, science, technology, engineering, art, etc. and to organize textbooks that make people feel the necessity and usefulness of mathematics. Third, sufficient learning of the principles of mathematics through the use of various actual teaching aids and mathematical models, and the construction of textbooks focusing on problem-solving strategies using engineering tools are needed. Fourth, in-depth discussions are needed on the timing of learning guidance for fractions and minority learning or how to organize and develop learning content.

This study aims to explore the direction of high school statistics education in Korea through a comparative analysis between the revised 2022 Korea mathematics curriculum and the IBDP Mathematics: Application & Interpretation Standard Level (IBDP AI SL) Curriculum and textbooks. The study seeks to investigate the Statistics unit of the two curricula, compare chapter structures and content elements of textbooks, and explore exercises on modeling and utilization of technology tools. The results are as follows: First, the IBDP AI SL statistics covered a broader range of topics. Second, exercises in Korean high school textbooks typically inquire about one or two questions in each topic, whereas the IBDP AI SL textbook's exercises present a real-life scenario on all relevant topics through sub-questions. Third, the Korean textbook guides the utilization of technology tools only in exercises presented after completing the entire chapter or where the calculation is complex. Also, there were only a handful of modeling exercises in the Korean textbook in contrast to most of the lessons and exercises were modeling exercises in the IBDP AI SL textbook. If these findings can be integrated into teaching practices in Korea, it will provide a direction for statistics education in Korean high schools.

The purpose of this study is to present the development direction of future reading education by examining the characteristics of reading materials within the high school textbook developed as the 2015 revised curriculum. For this purpose, reading materials of high school textbooks were analyzed in Korean language, mathematics, English, integrated science, and integrated social studies. The analysis criteria of reading materials were subject type, purpose, and student activities. As a result of the study, reading materials on various themes such as humanity, liberty, culture, environment, and district were presented in the integrated society and integrated science textbook of the 2015 revised curriculum. In particular, the Korean language curriculum was composed of a unit called "reading one book in one semester". However, most reading materials have no guidance on reading effective or reading direction, and lack of reading materials and information for extended reading. The reader's reading of the textbook was found to be simply supplementing the learning content of each unit or presenting fragmentary cues for conceptual purposes. This suggests that there is a lack of awareness of students' interest in reading, internalization of reading, and extension of reading. In this paper, we suggest supplementary materials of reading materials for expanding the high school textbooks, and explore the developmental relationship between textbooks and reading education through suggestions on aspects of textbook composition and teaching methods.

The 2007 revised social studies curriculum emphasizes history education in particular. Thus the contents of the history section previously scattered through 3rd, 4th, 5th and 6th grades are now integrated into the first and second semesters of the 5th grade in elementary social studies. Therefore, this research intend to gain insights that could be used as a reference when making next social textbooks by analyzing social textbooks of the 7th and the 2007 revised curriculum. The conclusions of comparative analysis on social textbooks of the 7th and the 2007 revised curriculum are as follows: The textbook units according to the 2007 revised curriculum were a reorganization of the contents from the 7th's 6th grade 1st semester contents per unit in a chronological flow. Meanwhile, the topic was introduced to supplement historic contents afresh. The 2007 revised curriculum focused on the life history, cultural history, personal history.

This study investigated a total of 529 integrated science teachers' implementation and changes to apply the curriculum-instruction-assessment. Data was collected through online survey on scientific competencies and skills, teaching-learning and assessment methods, changes of teacher's preparation, topics/materials, teaching-learning, and assessment to apply the curriculum-instruction-assessment as teaching integrated science. The results of the study were as follows: first, in the integrated science class, teachers implemented more on scientific communication and scientific inquiry among scientific core competencies, and analysis and interpretation of data collection and communication among scientific skills. Teachers often taught in lectures and used multiple choice items and short essay for evaluation. Teacher groups with less than 10 years of teaching experience appeared to be less active in teaching scientific core competencies and skills than those with more than 10 years. Second, Teachers have increased more time and efforts to search and to organize various materials in addition to textbooks, and try to integrated concepts in various fields to prepare learning topics and textbooks. Third, even though teachers made little change in implementing the process-oriented assessment, they used instructional strategies to increase student engagement in the integrated science class, restructured the instruction to provide immediate feedback after conducting the assessment. It is necessary to build a system that ensures fairness and credibility of evaluation while respecting the autonomy and professionalism of teachers.

This study analyzed the characteristics of organization scheme and the levels of core concepts in science textbooks used in Korea, Singapore, and Taiwan, which have shown superior achievement according to the TIMSS 2007. Science textbooks in Korea clearly divide the fields of Energy, Matter, Biology, and Earth, presenting the fields in nearly equal proportion in each grade. In the case of Singapore, science textbooks take an integrated content approach, combining concepts from several fields under a single theme. Science textbooks in Taiwan present a single content field in each unit. Also, because each grade engages in a specific field intensively, there are many cases in which concepts related to a single field are studied in a single grade. In view of levels of core concepts, Singapore or Taiwan showed higher achievement than Korea in themes of 'Cell and their Functions', 'Ecosystems', and 'Human Health' under the TIMSS 2007 biology field. Singapore introduces core concepts for these themes in lower grades compared to Korea and presents them repeatedly in several grades. In Taiwan, there are many cases in which these core concepts are taught only once during the course of $3^{rd}$ to $8^{th}$ grade, but the explanations are presented at a level that is suitable to TIMSS 2007 assessment objectives. Considering the results of this analysis, there is a need to reconsider the division of content fields and methods of presenting core concepts in the science textbooks of Korea.

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.

In this research, 'Construction Technology and Environment' units in 12 different technology home economics textbooks for 1st~3rd year middle school students under the 2009 Revised Educational Curriculum and the content system of textbooks were analyzed based on Reigeluth's elaboration theory, and the following conclusions were derived. First, each of the 12 different textbooks presented the elaboration process by procedural method and composed the content system. Second, the 'Construction Technology and Environment' unit presented many 'Thought Opening' as the systematization strategy of advance learning ability, and 'Unit Summary' presented at the end of the unit as the use strategy of the summarizer was presented preponderantly. In addition, 'Learning Objective' that represents the degree of achievement of the students after learning the unit was presented most as the use strategy of the synthesizer although there are differences in terms. In all of the textbooks, 'Figure,' 'Table,' 'Diagram', and 'Explanation of Terms' were used, and particularly, in the vitalizer strategy of the cognitive strategy, overwhelmingly greater number of 'Figure's, compared with all other elements, were presented as the vitalizer strategy of cognitive strategy. Finally, 'Compensatory Learning,' and 'In-depth Study' were presented as the learner control strategy in each of the 4 different textbooks, and there was one textbook that presents the term 'Supplement Reinforcement' in which compensatory learning and in-depth learning were integrated. Third, the metaphor utilization strategy among the 7 teaching strategies of the elaboration theory was hardly used in the composition items in units of textbooks.
