The purpose of this study is to compare and analyse the elementary school science curriculum and textbooks of South and North Korea, then gather the fundamental sources for the establishment of elementary school science curriculum after Unification of Korea by clarifying the difference and the likeness in educational objectives, contents, teaching methods of both Korean elementary school sciences. Based on this comparison and analysis, this study tried to give the concrete suggestions for the elementary school science curriculum and textbook development after Unification. For this, analyses were carried out for the curriculum managing systems, subject organization, education goal, emphasis on each field, teaching-learning and evaluation method. Besides, this study compared and analysed the elementary school science textbook development and distribution system, apparent format, content organization, ratio of content categories, content scope and level and the related terms appeared in both Korean elementary school science textbooks. The result of this study showed a lot of differences in the educational objectives, contents, and educational method of the elementary school science between South and North Korea. The grasping of these differences and the exact understanding about what causes these differences and how the differences are made must be the necessary work for the science curriculum establishment, especially for elementary school science curriculum and textbook development, after Unification.

This study aims to analyze the types of occupations that are presented through the illustrations in the elementary school textbooks specifically designated by the government, from a perspective of a digital world.. Types of occupations were analyzed from a perspective of digital world by analyzing the illustrations presented in Korean language, social studies and ethics textbooks of elementary school year 3~6. Occupations that would disappear in future were compared and analyzed from a point of view of a report, "The Future of Employment: How susceptible are jobs to computerisation?". As a result of the analysis, it was confirmed that the occupations presented in the textbook were not reflecting the change of society and occupations, and there was absolutely no reflection of the times at all that highlights SW. This study has a significance for proposing directivity regarding writing of new textbooks at a current situation of new textbook work being processed, based on the 2015 amended curriculum.

The purpose of this study was to investigate the inscription of North Korean Higher-Level Middle School 1 chemistry textbooks in the era of North Korean leader Kim Jong-un to understand North Korean chemistry education. The types and functions of inscription for each unit of the North Korean Higher-Level Middle School 1 Chemistry textbook were analyzed and compared with the inscription of the 'Chemistry I' textbook in South Korea. Inscriptions were analyzed by constructing an analysis frame based on previous studies. The analysis results were as follows. First, as for the types of inscription used in North Korean textbooks, photographs and illustrations were used the most, and graphs were used the least. Second, the functions of inscription used in North Korean textbooks had many exploratory and exemplary functions, and decorative functions were used the least. Third, there was no significant difference in type and function of textbook inscriptions from North and South Korea. The results of this study may be helpful in understanding North Korean chemistry education.

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.

This paper aims to analyze English vocabulary of the North Korean textbooks diachronically using the constructed English textbook corpus. The North Korea English textbooks attained from Information Center on North Korea of the Ministry of Unification are divided into before and after Kim Jong-Il era for the year of 1996 in which the curriculum revision has been conducted. They are stored as text files to analyse vocabularies using WordSmith Tools 7.0. The vocabulary size of the revised textbooks increased after the curriculum reorganization, but the number of vocabulary types and vocabulary diversity decreased. After the curriculum revision, it was found that lots of vocabulary related to the establishment of the Kim Jong-Il system appeared as the keyword. It was also found that some vocabularies reflected the economic and social life of North Korea. In addition, through comparison of the 100 high-frequency word list and keywords, it can be concluded that the vocabulary of the English textbooks of North Korea is gradually changing into communicative contents from contents related with written language.

This study compared and analysed computer textbooks of the middle school from South Korea and North Korea for preparing the unification of the Korean Peninsula. According to the result of this study, the contents of South Korea textbook were equally selected from all scopes. By contrast, the contents of North Korea mostly consisted of the basic knowledge of computer, word-processing excluding the newest contents as Internet or Multimedia. But with the BASIC programming and algorithm for enhancement of the creative solving ability, prospective IT brains had been trained in North Korea. Moreover, due to differences of language policy and country that delivered IT technology, significant differences were found between South and North Korea in IT terminology. For preparing IT education after unification of the Korean Peninsula, both efforts of people who work in the fields of IT and school system in South and North Korea should be taken in order to relieve these differences.

This study investigated the factors that should be considered when teaching proportional expression and proportional distribution through literature review. Based on these results, we analyzed and compared Korean and foreign mathematics textbooks on proportional expression and proportional distribution longitudinally and horizontally to search for desirable methods of organizing the unit of proportional expression and proportional distribution in mathematics textbooks. For longitudinal analysis, we took the mathematics textbooks according to the national curriculum since the 5th one. For horizontal analysis, we selected the mathematics textbooks of Japan, Singapore, and China. In each textbook, the contents and the order in relation to proportional expression and proportional distribution, the definitions of terminology, and the contexts and the visual representations for introducing related concepts are selected as the analysis framework. The results of analysis revealed many characteristics and the differences in ways of dealing contents about proportional expression and proportional distribution. Based on these results, we suggested some implications for writing the unit of proportional expression and proportional distribution in elementary mathematics textbooks.

Both Earth science II and Korean geography textbooks emphasize the importance of content related to 'geology of the Korean Peninsula'. This study aimed to analyze the differences in the content related to the 'geology of the Korean Peninsula' presented in the textbooks, and to find out whether these differences are consistent with the latest scientific knowledge in any inconsistencies are found. For this purpose, seven textbooks (four Earth science II and three Korean geography) published under the 2015 revised curriculum were selected as the subject of analysis, and the difference in the description of the tectonic provinces of the Korean Peninsula, geologic time scale, and explanatory texts of geological characteristics between Earth science II and Korean geography textbooks were compared. As a result of the analysis, there are some cases of inconsistencies between Earth science II and Korean geography textbooks in terms of terminologies, names, and distribution ranges related to the tectonic provinces of the Korean Peninsula. The Korean geography textbooks had inconsistencies in the geochronologic data of the rocks as they cited outdated data. In addition, inconsistencies were found in the explanatory texts describing the 'distribution of rocks on the Korean Peninsula', 'characteristics of the Pyeongan Supergroup', and 'great hiatus of the Paleozoic Era'. Both Earth science and Geography have many concepts in common, therefore, effort is needed to minimize the differences in content. It is important to select the content appropriately which should reflect the latest scientific knowledge and presents the concepts consistently.

The purpose of this study was to analyze inquiry activities in high school chemistry II textbooks on the revised 2009 curriculum. It also compared them to the textbooks based on the 7th curriculum, which were published by the same companies. The results in this study turned out to be as follows: First, the number of the activities and rate of inquiry activities per total pages were quite different from each publisher, and all of them decreased. Second, there were too many activities for specific inquiry process elements. Third, the types of inquiry activities differ slightly between each publisher. Experimenting and thinking were the most used while practicing was the least. Fourth, in the inquiry context, activities in scientific context were prevalent and activities in usual context were the second most common. Comparing to the text book on the 7th curriculum, the use of technical-social context increased, however, the technical-social context as well as the natural-environmental context were not used enough, as they constitute less than 10% of the activities. From these results, chemistry teachers should introduce a variety inquiry activities in chemistry curriculum for resolving those problems. Also, textbook developer should accommodate the results of research about science textbooks.

This study analyzed the introduction of addition and subtraction, including the composition and decomposition of numbers in the Korean, Singaporean, American, and Japanese elementary mathematics textbooks. The analytic foci of this study included visual models and their connections with the given problem contexts, the introduction of addition/subtraction or addition/subtraction sentences and their connections with the visual models, and additional activities for students to develop a relational understanding of the equal sign. The results of the analysis demonstrated diverse connections, mainly because the problem contexts, visual models, and the introduction of addition/subtraction or addition/subtraction sentences were implemented differently for each textbook. There were differences among the textbooks in what order of problem contexts were presented. Regarding the use of visual models, two textbooks tended to use one model consistently, whereas the other textbooks used various models depending on the problem contexts. There were subtle but significant differences in introducing addition/subtraction or addition/subtraction sentences. For a relational understanding of the equal sign, all textbooks included activities emphasizing that both sides of the equal sign are equal. Based on the results of this study, this paper closes with several implications related to the problem contexts to introduce addition/subtraction and addition/subtraction sentences as well as the use of visual models, which can serve as a basis for a new unit for the subsequent textbook.
