In this study, we analyzed the PCK components in the materials units of the third and fourth grades of the Korean government-authorized teacher's guides for elementary school, developed in the 2015 revised national curriculum. The results showed that the PCK components were presented in a relatively balanced manner compared to the teacher's guides for middle school. Knowledge of the subject matter accounted for the highest proportion, and knowledge of instructional strategies in science accounted for a higher proportion than knowledge of the science curriculum. The knowledge of assessment in science showed the greatest deviation among publishers, and knowledge of students tended to show the lowest. By subcomponents, experiments and inquiries had a higher proportion than concepts and theories. The ratio of horizontal articulation was lower than that of vertical articulation or lesson objectives, and lesson objectives were presented in various ways, such as in core competencies and achievement standards for science. As questioning was emphasized, teaching strategies and questioning appeared at a similar rate. Motivation and interest, misconceptions were linked to teaching strategies and questioning. In some cases, assessment items and assessment criteria were presented at each level, and various PCK components were linked to these two components. Components with relatively large differences among publishers were supplementary or in-depth concepts, inquiry in textbooks, instruction sequence and method, subject-specific strategies, and assessment items. From the results, the implications for the development of teacher's guides were discussed.

This paper has analyzed contents of copyright education in Informatics textbook in middle school curriculum and has proposed ways to enhance copyright education. In this paper, we have analyzed Informatics curriculum, authorized textbook, and teacher's guide book for middle school revised in 2007 and have extracted contents and systems of copyright education in Informatics course. We examined studies on the copyright education and analyzed on the basis of interest, understanding, usage, and practice of copyright. As a result, copyright education has turned out to be focused on 2nd level of information society and information technology. We found that copyright education was necessary both directly and indirectly in various parts and levels in that it is an optional subjects. This paper suggests the possibility of copyright education in Informatics curriculum for middle school and the copyright education is expected to be reinforced.

This study analyzed the unit of child rearing in four Household textbooks approved by the Department of Education during the 1920s-30s. These Household textbooks is contained a unit related to child rearing among Household textbooks approved by the Department of Education at that time. The results of the analysis are summarized as follows. First, the structure of the child rearing unit in the Household textbooks were largely composed of 'part, chapter and section' and this structure and contents were similar among all the textbooks. Second. in general, the four textbooks spared a large space for 'childcare,' nursing' and 'new-born babies and infants,' suggesting the importance of these contents. Third, cautions for pregnant women were taught to call attention not only of pregnant women but also of their families to importance of pregnancy. Fourth, the child rearing unit contained many illustrations and pictures and some pictures were shared among the textbooks. Firth, in acquiring medical knowledge related to diseases, the textbooks demanded child-rearing mothers to 'observe' and 'scrutinize' any symptoms appearing in the child. These contents were connected with commercial products but far distant from the realities. The detailed method of 'nursing' also required a lot of time and accuracy impractical in real life.

Now, mathematics textbook is being developed in accordance with the 7th educational curriculum. It is expected that qualified textbook reflecting 'differentiated education' concept be developed and published. But there are still many limitations of textbook authorization system to develop 'such' textbook. Many authors of textbook have difficulty in developing creative and qualified textbooks in their own way. In this paper, we deal with what the authors should keep in mind and could reflect related on textbook authorization system in developing textbook. For this purpose, focusing on new 'content principle' of mathematics textbook authorization, the paper presented its educational background.

Photographs and illustrations are integral parts of current science textbooks' inscriptions. This study analysed and compared the function and structure of photographs and illustrations used in high school earth science textbooks of the 6th and 7th national curriculum. The findings of the function analysis showed that 'illustrative' function was far superior to other functions in terms of frequency and ratio. The illustrative function varied more in the 7th curriculum textbooks, especially in earth science I. 'Explanatory' and 'complementary' functions, which were relatively ignored in the 6th curriculum, significantly increased in the 7th curriculum textbooks. 'Decorative' function increased on the whole. The results of the structure analysis revealed that indexical reference remarkably decreased in the 7th curriculum textbooks, which means the retrogression of co-deployment with main text. 'Multiple' organized photographs and illustrations significantly increased in the 7th curriculum textbooks, while 'pair' and 'series' organization did not show an increase at all. It was suggested in this study that 'inquisitive' function and 'complementary' organization should be supplemented in terms of both function and structure. Moreover, the functional and structural aspects of scientific inscriptions including photographs and illustrations should be utilized by the certification criteria of science textbooks.

Purpose : The purpose of this study is to investigate the material in middle school and high school textbooks covering child care and children's health for medically inaccurate content and to make sure that the correct information is given to students. Methods : We have examined 47 kinds of textbooks on the subjects 'Home economics' and 'Technology and home economics' published in 2007 to find out how much importance is placed on children's health and childcare and to search for incorrect definitions, inaccurate facts or insufficient explanations. We have also analyzed the credentials of the writers of these textbooks. Results : Textbooks of middle school cover psychological and physical changes during adolescence and nutrition, and those of high school cover marriage and childcare. These materials covering health made up 27.5%, 11.7% of middle & high school texts. Age definitions of neonate and infant were incorrect. Inaccurate facts were mostly about fontanelles, primitive reflexes, breastfeeding and weaning. There also were wrong informations on the umbilical cord care and developmental milestones during infancy. The childhood immunization schedules and the growth curves were not up to date. Most of the authors major in home economics and the others were school teachers. There was no evidence of any review by a medical society or an expert. Conclusions : When writing about children's health and childcare in textbooks, a board-certified pediatrician or The Korean Pediatric Society should be consulted to provide accurate medical information to middle and high school students.

This study was analyzed that what kind of elements for STEAM, except scientific commonsense, are contained in 2009 revised chemistry textbooks I for high school students. So first, elements of STEAM in textbooks were examined by following three sections; by publishing company, each unit and area of textbook. For reference, new sub-elements of STEAM were set because existing elements of STEAM is incongruent with current textbooks. As a result, most chemistry textbooks included elements of STEAM properly for inter-related learning with the other fields. Every textbook had its unique learning methods for utilizing elements of STEAM and they were unified as one way. Depending on textbooks, learning methods were little bit different from the others. Also, detailed elements of STEAM contained in textbooks were classified just 14 types. And they were even focused on a few elements according to sort of textbook. Thus, it seemed that there was a certain limitation of current education of STEAM in chemistry Field. By the unit, according to the curriculum, contained elements of STEAM were different. Almost all elements of STEAM were located in I section. Consequently, it is difficult to include elements of STEAM if mathematics or history were not existed in curriculum. Lastly, by the area, most of all elements of STEAM were included in reference section. Almost all elements of STEAM were focused on art and culture. Thus, STEAM was used for utilization about chemical knowledge in substance. Otherwise, convergence training for approach method was not enough in chemical knowledge.

This study attempted to analyze the contents of Practical Arts(Technology Home Economics)Textbooks written by the 7th national curriculum in a gender equity education. The objective of this study was to suggest some improvements which should be solved in terms of gender equity in Practical Arts, Technology and Home Economics education through analyzing their teaching and learning contents. Quantitative analysis were carried out for the objective of this study, Practical Arts(Technology Home Economics)Textbooks were divided into Technology and Home Economics fields. The pictures and illustration were analyzed in terms of sexual discrimination considering the social status and role. The analysis results were as follows. First, there were few cases of sexual discrimination in the texts. On the other hand, there were some cases of sexual discrimination in the pictures and illustration. Considering the results of some studies carried out in the 6th national curriculum, many problems raised in a gender equity education standpoint in the studies were solved. However, there were some cases of sexual discrimination which should be improved in the textbooks written by the 7th national curriculum. Second, there were few cases of sexual discrimination in Practical Arts textbooks. On the contrary many problems in terms of gender equity education were found in the textbooks of Technology and Home Economics. This result may be caused by the characteristics of Technology and Home Economics. The traditional viewpoint toward Technology and Home economics Textbook needs to be changed. In other words, their textbooks have to include practical contents for the positive sense of value and right sexual roles in terms of gender equity education. The contents of Practical Arts(Technology Home economics)Textbooks should be designed considering the articulation among the subjects and grades especially in terms of gender equity education.

This study analyzed the frequency and level of scientific practices presented in secondary science textbooks. A total of 1,378 student activities presented in 14 middle school science textbooks and 5 high school integrated science textbooks were analyzed, using the definition and level of scientific practice suggested in the NGSS. Findings show that most student activities focus on three practices. Compared to the textbooks for the previous science curriculum, the practice of 'obtaining, evaluating, and communicating information' was more emphasized, reflecting societal changes due to ICT development. However, the practice of 'asking a question', which can be an important element of student-led science learning, was still rarely found in textbooks, and 'developing and using models', 'using math and computational thinking' and 'arguing based on evidence' were not addressed much. The practices were mostly elementary school level except for the practice of 'constructing explanations'. Such repeated exposures to a few and low level of practices mean that many future citizens would be led to a naïve understanding of science. The findings imply that it is necessary to emphasize various practices tailored to the level of students. In the upcoming revision of the science curriculum, it is necessary to provide the definition of practices that are not currently specified and the expected level of each practice so that the curriculum can provide sufficient guidance for textbook writing. These efforts should be supported by benchmarking of overseas science curriculum and research that explore students' ability and teachers' understanding of scientific practices.

In this study the concepts for science learning of physics and earth science presented in the seventh grade science textbooks for the seventh national curriculum of Korea approved by the ministry of education were analyzed in terms of the concrete and formal concept level. The parts of textbook analyzed for science learning consist of three sections in physics such as light, force, and waves, and three sections in earth science such as the structure of the earth, the substance of crust, and the movement and composition of the ocean. The analyzed results showed that the number of scientific concepts were differed from 54 to 74 in physics and from 86 to 120 in earth science depending upon publishers. In general, the concepts for science learning in the physics were found to be more in the formal level than the concrete level. However, the concepts for science learning in earth science were found to be more in the concrete level than the formal level. The analyzed results suggest that the concepts of science learning should be considered the learner's cognitive level and the sections should be disposed depending on the degree of difficulty for writing the science textbook. Therefore, it seems to be important to review carefully whether the textbook meets the object of the seventh curriculum of Korea during the process of the investigation for the science textbook.
