Purpose: This study purposed to examine the effect on health educational curriculum by grasping knowledge, attitude, and the extent of practicing it after giving a health education curriculum for 17 hours. Methods: This study was a non-equivalent control group pretest-posttest conducted with the first-graders enrolled in a middle school students in Gyeonggi Province. A total of 191 completed questionnaires from the test group and the control group each were used for the final analysis. The survey period was from March 5 to March 13, 2009 before the education was given from July 20 to July 25, 2009 after the education. A total of 38 questions were used to measure knowledge and a total of 39 questions were used to measure attitude and practice. This study used $x^2$ test, ANOVA, and t-test, Paired t-test. Results: After the health education curriculum was given, the test group s knowledge of health education was found higher than that of the control group. There was a difference between two groups, but considering the perfect score of 38, the knowledge scores of both groups were not high. With regard to each group s attitude and practice of health education, the study compared the scores obtained before and after the education and found that the test group had higher scores than the control group, showing a significant difference. Conclusion: In order for a health education curriculum to successfully have favorable influence on the health of teenagers, the curriculum should be offered for a more extended period of time than 17 hours and as a compulsory course, not a selective one, so that all the students can develop their health management capabilities.

The purpose of this review was to introduce and examine 'development' and 'relations' as the core concepts of Home Economics in 2015 revised middle school curriculum in Korea. The 2009 and 2015 proclamation of the ministry of education on home economics curriculum and 26 published middle school textbooks were reviewed. The major findings were as follows. First, the components of human 'development' and family 'relations' were strongly associated with promoting four key competencies (i.e. the self-management competency, the communication competency, the aesthetic sensibility competency, the community competency) of 2015 revision. Also, four of cross-curricular learning topics (i.e. character education, multicultural education, safety and health education, human right education) in 2015 revision could be effectively discussed with human 'development' and family 'relations'. Second, when teaching and learning of the core concept, human 'development', continuous dynamic aspects of life-span development, the connectedness of different domains of development, systematic approach of various concepts in development, specificity and empirical evidence of information and variability of developmental patterns in adolescence should be considered. Third, when teaching and learning of the core concept, family 'relations', family trait such as generational relations, gender relations, role relations and power relations should be taken into account. In addition, exclusively focusing on normal family ideology or image of middle-class family and lecture-centered instruction methods should be changed for students to achieve the competencies relevant to family relations. The future directions for applying core concepts, 'development' and 'relations' in classroom will be discussed.

In this study, we analyzed the explanations and examples of Brønsted-Lowry model in Chemistry I and Chemistry II textbooks of the 2009 revised curriculum. In particular, the definition of the Brønsted-Lowry model, the examples, and the content of experiments were analyzed by the process perspective of chemical equilibrium, emergent process. The analyzed textbooks were 4 kinds of Chemistry I textbooks and 4 kinds of Chemistry II textbooks in 2009 revision curriculum. As a result, Chemical I textbooks did not adequately show the chemical equilibrium viewpoint when explaining the Brønsted-Lowry model. In the Chemistry II textbooks, the examples of Brønsted-Lowry model were not present emergent process viewpoint, and those were described as sequential viewpoint of Arrhenius model. In addition, examples of experiments to demonstrate the Brønsted-Lowry model of Chemistry II textbooks were insufficient. The experimental examples related to the definition of acid bases were at the level of classification by the color change of indicators. The experimental examples for explaining the strength of acid and base were to compare current intensity or amount of hydrogen gas generated from the reaction with metal. In addition, all textbooks presented the state of aqueous solution when describing the Brønsted-Lowry model, causing problems with differentiation from the Arrhenius model. Therefore, it is necessary to develop examples of experiments to help students understand Brønsted-Lowry model by presenting acid and base reaction in the non-aqueous solution state.

Depending on the type of textbook, the word and mathematical notation expression used in high school mathematics textbooks varied and there were also some differences on the mathematical definition and the content description methods. Not only the composition of textbooks but also various expressing ways of textbooks have significant impacts on teaching and learning of teacher and student. The diversity of expression had pros and cons like both sides of a coin. There is a positive aspect that we can pursue pedagogical diversity. Simultaneously there is a negative aspect that the possibility of acting as a learning burden exists in the viewpoint of the student and the equality of evaluation may be undermined. In this study, Preferentially we focused on analyzing the actual situation rather than judging what is more appropriate about the diversity of words and notation expressions used in mathematics textbooks which is based on the current curriculum. For this purpose, we analyzed 56 kinds of mathematics textbooks based on the 2009 revised mathematics curriculum, and presented four aspects(terms expressing, notations expression, mathematical definition, content description method) with examples about differences of the various expressions used in textbooks including 'terms and notations'.

Using text network analysis, this research aimed to identify significant keywords associated with each period of the revised High School Engineering curriculum from 2009-2022 and to examine their interrelationships in order to analyse the observed changes. The results of this study can be summarised as follows. Firstly, a significant increase in the number of words was observed throughout the curriculum revisions, with prominent occurrences of terms such as 'engineering', 'understanding', 'problem', 'solution', 'learning', 'evaluation' and 'diversity'. Secondly, network analysis and examination of connection centrality for each subject revealed the connection relationship that represented distinct subject characteristics. Thirdly, the study of the engineering curriculum revealed shifts in emphasised content with each revision. Based on these findings, recommendations were formulated. Firstly, given the growing importance of engineering, it is imperative to conduct systematic research on engineering education in primary and secondary school contexts. Secondly, efforts should be made to strengthen the link between Engineering and Technogy･Home-economics subjects in secondary schools. Finally, high school engineering subjects should be used not only to explore engineering careers, but also to cultivate talents with interdisciplinary expertise.

Environmental education contents in science textbooks of South Korea and the United States were compared and analyzed in order to find how to develop environmental education in elementary science education. McGraw-Hill science textbooks for third to sixth grade and science textbooks of Korea based on the 2009 Revised National Curriculum and the 2007 Revised National Curriculum were analyzed and compared. The categories were educational goals, kinds of contents, distributions of contents and tense. The result showed that the environmental education goals in science textbook of Korea and United States were biased to knowledge area. The educational contents of the United States was higher 2.5 times then Korea and distributed in all areas. In quantitative distributions in Korea were biased some special areas. Tense of educational contents were almost present. Attitudes and recognition of students varies gradually over a long period of time, the contents of environmental education will be useful "evenly distributed" for all areas and school year.

2009 revised national curriculum for mathematics emphasizes the mathematical processes which consist of mathematical problem solving, mathematical reasoning, and mathematical communication. This study focused on applying these processes to an elementary school class for mathematics. Even though they say that it is desirable that the mathematical processes are realized in every mathematics class, any vague intention for their application without specific plans is apt to be apart from meaningful practice. Therefore this study proposed a lesson plan about the characteristics and the comparison of bar graphs and line graphs for 4th grade students based on the mathematical processes. And we applied it to 27 subjects. By observing and analyzing their activities and communications, we discussed about the guidelines of applying the mathematical processes to elementary school classes for mathematics.

In this study, we analyzed what STEAM-related subject contents, except mathematical knowledge, are contained in 2009 revised elementary mathematics 6th grade textbooks and teacher's manuals. The STEAM-related subject contents in the textbooks and the teacher's manuals were examined by unit, by semester, and by strand of the content in the elementary school mathematics curriculum. The results are the following: First, in each unit and in each strand of mathematics, the most frequent STEAM-related subject content is storytelling, followed by the STEAM-related subject contents of technology and engineering, natural science, and social studies in order. On the other hand, the number of culture, physical education, music and fine arts contents is very small. Second, the number of STEAM-related subject contents in the textbook for the second semester(textbook 6-2) of the 6th grade year is 61 more than that in the textbook for the first semester(textbook 6-1). The number of non-storytelling STEAM-related subject contents in textbook 6-2 is 107, 2.7 times more than that in textbook 6-1. Third, the teacher's manual for textbook 6-1 is insufficient in complementing the textbook units which lack in STEAM-related subject contents, while the teacher's manual for textbook 6-2 is comparatively good in its complementing role. Therefore, it is recommended that we develop different STEAM materials for our 6th grade mathematics classes.

The 2009 revised curriculum emphasizes science writing as a way to foster scientific thinking, creative thinking and communicative abilities. This research attempted to find out the aspects of science writing in science textbooks by analyzing seven versions of the 2009 revised science textbooks. The results of the analysis are as follows. First, it was found that the proportion of science writing pages is small and the amount of science writing differs a lot depending on the kind of textbook. Also, science writing is generally located in the wrap-up part of each unit, and the amount and the number of science writing vary substantially from unit to unit depending on the textbook. Second, it was found that 'scientific knowledge-explanation' statements have the largest proportion and 'STS-assertion' statements have the second largest proportion in terms of topics and styles of science writing in science textbooks. Some 'scientific knowledge-explanation' statements are not appropriate to foster scientific ability because they evaluate reading comprehension of the suggested passage as nonliterary writing, not the writing itself as a method to learn science. Third, it was found that there are many predicates that do not indicate a clear purpose of the science writing contained in science textbooks.
