The purpose of this study was to analyze the changes in home management part in the home economics textbooks for middle school from the 1st to the 7th curriculum period. The part of home management in the all of home economics textbooks published in every curriculum period was analyzed using several external criteria of textbook. The major findings of this study were as follows : 1. The part of home management was divided into even specific areas including 'definition and process of home management'. 'time management'. 'household labor/work management'. 'family financial management'.'purchasing'. and 'consumer protection'. 2. The part of home management has been included in the middle school home economics textbooks since the 1st curriculum period. The proportion of this part in the whole textbook varied with range from 5.1% to 31.8%. 3. The areas emphasized in the beginning of curriculum period were 'family financial management'and 'household labor/work management'. and 'utilization of family resource and environment management'were the areas emphasized in the later curriculum period. 4. The titles of the middle and small unit have begun to use recent words and have represented the including contents since the 4th curriculum period. 5. The numbers of illustrations. tables. pictures. and activities have increased since the 6th curriculum period. 6. Other unrelated areas such as computer and career preparation were included in the home management part in the 1st. 2nd. and 5th curriculum period.

Developing middle and high students' information literacy and creative problem-solving skills in this information-oriented society is very important and for this reason, the subject of informatics has been established. However, little research on creative problem solving literacy of informatics textbooks has been conducted. Therefore, the purpose of this paper is to quantitatively analyze whether 'problem-solving methods and procedures' parts in informatics textbooks in middle schools present creative problem solving literacy or not and in what degree. Data were quantitatively analyzed using the Gil-Su Choi method. The result of data analysis indicated that all the textbooks turned out to be correct range in the category of the "composition of various learning activities," but got out of range in some categories such as "problem-solving process reflection" and "problem-solving strategy proposal". Also a few textbooks haven't satisfied in important indexes and activities. So, we suggest that more 'problem-solving process reflection' and 'problem-solving strategy proposal' parts should be included in the informatics textbook and more various forms of learning activities be utilized well as the ratio of activities needed primary and high mental processes be kept the balance.

One of the major goals in high school Informatics is for students to develop creative problem-solving abilities based on knowledge on computer science. Thus, the contents of the textbooks should be accurate and appropriate. However, we discovered that the current Informatics textbooks contain the untrue and/or inappropriate descriptions of main memory and virtual memory. The textbooks describe that main memory is composed of RAM and ROM. The virtual memory is described as a technique in which a part of the secondary storage is utilized as main memory to execute an application of which size is larger than that of main memory. In this study, we attempted to uncover the root causes of the fallacies, and suggest the accurate explanations by comparing with renowned books adopted in most schools worldwide including USA. Our study reveals that it is inappropriate to include ROM in main memory from the memory hierarchy perspective. Virtual memory is a technique that provides convenience to programmers, through which an operating system loads the necessary portion of a program from secondary storage to main memory. As for the advantages of virtual memory in the current computer systems, the focus should be on providing the effective multitasking capability, rather than on executing a larger program than the size of main memory. We suggest that it is appropriate to exclude virtual memory in textbooks considering its complexity.

This study examined the types of explanations related to physical change and chemical change in the science textbooks of middle and high school based on the prior study of science teachers' understanding. For this research, the researchers analyzed 44 textbooks of middle school science and high school chemistry. As a result, there were no explanation or property type explanation represented in most of the textbooks related to physical and chemical change concepts. Also, there are few relationship represented between physical change and chemical change, and the examples related to physical change and chemical change were confused. These representations of textbooks can give rise to confusion of understanding of teachers and learners. So, it needs to re-design the explanation types correctly and constantly in science textbooks related to physical change and chemical change.

The revised informatics is to be compulsory for middle school students from 2018 according to 2015 revised curriculum. The concept of abstraction in informatics curriculum has common features and differences compared with general abstraction, however there is a mix of concepts in the current informatics textbook. The abstraction of computational thinking needs to connect with automation, so it is difficult to teach correct concept of abstraction with these textbooks. Therefore, this research conducted to investigate several informatics textbooks that were developed by the revised curriculum and to analyze the concept and examples of abstraction. As a result, some textbooks have that there is a mix of concepts about general abstraction and no connection with automation. This research suggests clarified abstraction and educational examples for cultivating computational thinking to improve this situation. This result will be basic recourse for the reconstruction of abstraction lesson to improving computational thinking.

In the seventh mathematics curriculum, the use of technological tools including calculator and computer are generally recommended through the seventh subjects related to mathematics emphasized, and especially in 'Applied Mathematics' subject, their use are more strongly emphasized and reflected. The total four kinds of textbooks of Applied Mathematics includes contents on their use. This study investigates what are contents on calculator use, how they are developed and constructed in Applied Mathematics Textbook. Furthermore, this study is focused on the analysis and comparison on those factors of four kinds of textbooks. Based on these results, this study ultimately hope to suggest how effectively calculator use be developed and constructed in textbook both in Applied Mathematics and the other mathematics subjects.

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 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.

Computational thinking has been a powerful key recently to open a new paradigm era in the curriculum of Informatics subject and the community of computer science education. But the quality and quantity of domestic research about it has been very poor in comparison with other countries. Therefore, this study focuses on the definition, learning steps and learning contexts about computational thinking education using some professional questionnaires and analyses of related other countries' literatures. The learning contexts that were extracted by several previous works could be used as the factor to analyze the curriculum of Informatics subject and textbooks in middle school; these could be helpful to teach the ability of computational thinking in middle school. Results of these questionnaires show that the three steps and 13 learning contexts of computational thinking education are properly well-formulated. The 5 of 13 learning contexts, such as data collection, are missing in 2009 revised-Informatics curriculum in middle school as well as the seven Informatics textbooks that used in middle school contained 10 of 13 learning contexts for computational thinking education.
