This study examined how practical reasoning processes were reflected in the revised consumer education of technology & home economics textbooks in secondary schools. Twenty-four textbooks from secondary schools for 7th to 10th grades were analyzed. Areas of textbooks analyzed were introduction, body content, learning activity, and evaluation. Analysis criteria were extracted from the previous literature regarding contents and questions dealing with practical reasoning processes and revised by a researcher of this paper. The results and conclusions of this study are as follows. The results of the analysis of the practical reasoning processes showed that, across all grades, "contexts" was the most common element, and "alternatives and means" was the second most common elements. The elements of "consequences", "action and reflection" were less represented in the textbooks, with the exception of the learning activity part. The types of practical reasoning process reflected were classified either as the entire process of reasoning being reflected or some of the process being reflected, or included in the body content. Most of these were some of the process being reflected. Since there were a lot of concept-oriented statements rather than questions, more practical reasoning questions should be developed to increase the reasoning process. In addition, a need exists to develop a variety of ways to utilize the entire practical reasoning processes in the textbooks to help teachers apply the practical reasoning processes to their lessons.
Geological information on the Korean Peninsula plays a significant role in science education because it provides a basic knowledge foundation for public use and creates an opportunity to learn about the nature of geology as a historical science. In particular, the Mesozoic Era, when the Korean Peninsula experienced a high degree of tectonic activity, is a pivotal period for understanding the geological history of the Korean Peninsula. This study aimed to analyze whether content regarding the geology of the Mesozoic Era are reliably and consistently presented in the 'Geology of the Korean Peninsula' section of Earth Science II textbooks based on the 2015 revised curriculum. Four textbooks for Earth Science II were analyzed, focusing on the sedimentary strata, tectonic movement, and granites of the Mesozoic Era. The analysis items were terms, periods, and rock distribution areas. The consistency within and among textbooks and of textbooks and scientific knowledge was analyzed for each analysis item. Various inconsistencies were found regarding the geological terms, periods, and rock distribution areas of the Mesozoic Era, and suggestions for its improvement were discussed based on these inconsistencies. It is essential to develop educational materials that are consistent with the latest scientific knowledge through collaboration between the scientific and educational communities.
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.

The purpose of this study is to test content validity of a portfolio assessment and to analyse the information which can be obtained from student portfolios. The content validity of the portfolio was tested against the objectives of each lesson and the emphasis of curriculum. The information was identified from the analysis of student portfolios. Students' portfolios from a fourth grade class in Pyeungteak, Kyeungki-do were used for analysis. The portfolios included students' evidence of learning on (I) Strata, Unit 2 'Strata and Fossil,' and (3) Change of Object by Heat, Unit 4 'Heat and Change of Object'. Fourth-grade science textbooks were also analyzed to understand the base level information for portfolio analysis. Two science education specialists and ten elementary teachers majored in science education took part in this analysis. The results of the analysis showed $70{\sim}100%$ of agreement between the objectives of lesson and portfolio forms. Over 90% of agreement is reached between portfolio forms and the emphasis of the curriculum. Student portfolios revealed much information on comprehension, observation, will to study, and process of learning. They also revealed some information on drawing conclusion, communication. self-direction, progress of learning, self-concept, interaction, and process of learning. As a whole, the information in students' portfolios is similar with that dealt in science textbooks. However, students' portfolios have more information on anticipation, will to study, self-direction, and interaction. On the contrary, science textbook deals more with information on observation, planning inquiry, than students' portfolios. The portfolio assessment examined has very sound content validity. The results also show that much more and various information which can not be obtained from pencil and paper test could be obtained from student portfolios. The use of information, obtained from student portfolios will make it possible understand students' learning. their strength and weakness, hence improve student' science learning.
The purpose of this study is to analyze the current status of and suggest future improvement practices for cultural heritage education in primary school. We analyzed a primary school textbook for each of five subjects (Korean, social studies, music, art, physical education), surveyed ten teachers with cultural heritage education experience, and analyzed the results. Based on the results, we made the following five suggestions: First, the goal of cultural heritage education should be expanded to foster citizenship. Second, in cultural heritage education, it is necessary to discuss what should be included in the educational content and to organize the content systematically in connection with the student environment, local community environment, and subject content. Third, cultural heritage education should be linked with sustainable development so that cultural heritage can be passed on from the present generation to future generations. Cultural heritage has characteristics, such as universal values of humanity, that transcend national boundaries, regional identities, dialogue and understanding between civilizations, and sources of creativity, and thus serves as the foundation for sustainable development. Fourth, for the effective implementation of cultural heritage education in schools, it is necessary to develop step-by-step teacher training programs. The success or failure of cultural heritage education in schools depends on teacher training. Fifth, the degree to which cultural heritage education is integrated into the curriculum should be strengthened, allowing learners to be educated so that they can cultivate knowledge and critical thinking about cultural heritage, enjoy and protect it, and connect with a sustainable society.

Despite the significance of the measurement strand in elementary mathematics education, it is not easy to teach it meaningfully. This study analyzed instructional methods related to capacity and weight in a series of mathematics textbooks of Korea, Japan, Singapore, and the US. The overall analysis was conducted in the following two aspects: (a) what and when to teach main learning content, and (b) how to teach the learning content tailored to the instructional components specific to the topics of measurement (i.e., the necessity of measurement unit, the meanings of measurement terms, appropriate choice of units, appropriate choice of measurement tools, and the necessity of calculation). The results of this study showed overall similarities in using real-life contexts to teach major topics on capacity and weight as well as emphasizing the relations among measurement units. However, noticeable differences were also analyzed in dealing with the meanings of measurement terms, appropriate choice of units, and appropriate choice of measurement tools. Based on these results, this study provides textbook writers with implications on what to further consider in dealing with capacity and weight.

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.
Unfortunately, we have poor knowledge of medical technology in North Korea. This study has thus attempted to identify the level and status of medical technology development through analyzing the contents of medical textbooks currently in use. This study has assumed that three factors are influencing the level and status of medical technology in a society ; the level of socio-economic development in general, the level of scientific technology revolution and health policy. Forty textbooks are collected for this purpose. The main findings are summarized as follows : 1) North Korea s strengths in that (1) its herb drugs, which are in a broad use, are cheaper, more safe and more attainable than bio-equivalent chemical ones, and (2) the development of its medical technology was carried out with emphasis on the practical and basic health needs. 2) North Korea has weaknesses in that (1) its medical diagnostic method largely depends on manual procedures, (2) the R & D investment in the development of chemical drugs, especially antibiotics, is very small, (3) the amount of medical equipments is in a absolute shortage, and (4) the medical technology is destitute of specialty, caused mainly by the overemphasis on Juche-Uihak or herb medicine. 3) Medical technology has two faces, positive and negative so that it cannot be successfully evaluated by one. It eventually acts a positive function for public health through developments of drug, equipment and new medical treatment method. But it is also true that it has negative effects such as the dehumanization of high cost medical technology, cost hike due to over-investments in expensive equipment and the absence of wholistic care from overspecialization. 4) We have to consider economic status and the social needs of medical care in order to evaluate the medical technology of a society. It is also the case with North Korea. A whole picture of the North Korean medical technology could be understood only if further comprehensive studies of medical technology are to be carried out for North Korea.

This study aimed to identify the effects of using storytelling techniques in sex education, in which students are encouraged to talk about their experiences with sex and love and helps them form their own sex values and decision-making skills related to sex. A five-period teaching-learning plan covering issues including safe, considerate and responsible sex was developed using the storytelling technique for 134 first-year students in 4 classes. 134 questionnaires were administrated through pre-and post-test and 38 worksheets applying a variety of storytelling activities were analyzed using content analysis. Students were found to have gained a more positive outlook on relationships and a considerate attitude towards others in sex. There was also a significant increase in items considering safe sex, including perceptions on contraception methods and selection of safe contraception methods. The students' sense of sexual responsibility was also enhanced. Results of content analysis found students to have shifted to sex focusing on love and responsibility, and to have grown a stronger sense of responsibility in their relationships. Furthermore, the respondents expressed interest in selecting proper contraception methods and held strongly negative perceptions about abortion.
Trigonometry allows us to recognize the usefulness of mathematics through connection with real life and other disciplines, and lays the foundation for the concept of higher mathematics through connection with trigonometric functions. Since international comparisons on the trigonometry area of textbooks can give implications to trigonometry teaching and learning in Korea, this study attempted to compare trigonometry in textbooks in Korea, Australia and Finland. In this study, through the horizontal and vertical analysis presented by Charalambous et al.(2010), the objectives of the curriculum, content system, achievement standards, learning timing of trigonometry content, learning paths, and context of problems were analyzed. The order of learning in which the three countries expanded size of angle was similar, and there was a difference in the introduction of trigonometric functions and the continuity of grades dealing with trigonometry. In the learning path of textbooks on the definition method of trigonometric ratios, the unit circle method was developed from the triangle method to the trigonometric function. However, in Korea, after the explanation using the quadrant in middle school, the general angle and trigonometric functions were studied without expanding the angle. As a result of analyzing the context of the problem, the proportion of problems without context was the highest in all three countries, and the rate of camouflage context problem was twice as high in Korea as in Australia or Finland. Through this, the author suggest to include the unit circle method in the learning path in Korea, to present a problem that can emphasize the real-life context, to utilize technological tools, and to reconsider the ways and areas of the curriculum that deal with trigonometry.
