The goal of the textbooks of 2009 revised curriculum is to make customized lectures possible considering learning characteristics and understanding level of students. However, it is not easy to find a research result on sensed difficulty of the mathematics textbook, which is able to provide valuable information on the development of the diverse level textbooks. This research suggested criteria in analysing sensed difficulties of field teachers on the textbooks, and analysed sensory difficulty on the selective tracks textbooks based on 2007 revised mathematics curriculum using the criteria. The results of the analysis on 59 mathematics selective tracks textbooks show that all have average sensed difficulty. The criteria and research results are expected to provide valuable information in future mathematics textbook development.

In this study, the readability of the texts in the third and the sixth grade science textbooks developed under the 2007 revised science curriculum were analyzed in terms of word and sentence units. In the word unit analyses, the levels of the words in the texts were classified into four categories, 1st to 4th levels. In the sentence unit analyses, the sentences in the texts were classified either a simple sentence or compound/complex sentences, and the average length of the sentences was also calculated. The results indicated that more than 90 percents of the words in the 2007 revised science textbooks were classified as the 1st to the 3rd levels. However, both the kinds and the frequencies of the words in the 2007 revised science textbooks were increased in comparison of those in the 7th science textbooks. In particular, it was found that the increasement in the 3rd grade science textbook was noticeable. The ratio of the compound/complex sentences in the 2007 revised science textbooks were increased in comparison of those in the 7th science textbooks. The average length of the sentences in the 2007 revised science textbooks was also increased.

In this study, we investigated the characteristics of the reading materials in the elementary school science textbooks in order to obtain implications for the effective use of them. The reading materials in the elementary school science textbooks developed under the 7th and the 2007 revised National Science Curricula were analyzed. The criteria for classifying the reading materials were the type of theme, purpose, students' activity, the type of presentation, the type of images, the role of images, and readability. The results indicated that the reading materials in the 2007 revised science textbooks are more systematic than those in the 7th science textbooks in terms of their length and their distribution among energy, matter, life, and earth areas. It was also found that various types of reading materials are presented in the 2007 revised science textbooks covering new themes such as frontier science, job opportunity and career, and environment. In addition, the reading materials in the 2007 revised science textbooks introduce more visual images and the readability of them are also better than their counterpart. However, several limitations were still found to exist in the reading materials of the 2007 revised textbooks; most of them are non-inquiry and explanatory; most of the visual images are illustration and/or pictures. Educational implications are discussed.

In this study, the gender-role stereotyping of the texts and the illustrations in the elementary science textbooks developed under the 2009 Revised National Curriculum was analyzed, and the results were compared with those of the 2007 Revised National Curriculum. In the texts, there were significant differences between boys and girls in the frequencies of texts, two types of learning activities such as scientific inquiry and emotional expression, and housekeeping activity. Women outnumbered men in housekeeping activity, but they were much less than men to perform outdoor and professional activities. In the illustrations, there were not significant differences by gender in pupils, and these results are desirable in terms of achieving balance between boys and girls. However, the textbooks were found to favor the illustrations of men especially in outdoor and professional activities. Women also performed more in housekeeping activity. Compared with the adult results of previous curriculum, these results were not improved at all.

The Korean mathematical curriculum has been changed three times during the resent five years. It led to changes in textbook system. In the 2007 revised mathematics curriculum, workbook was developed focusing on student's self-oriented learning, effective practice in differentiated classroom, and mathematics problem solving considering individual difference. This paper examines the characteristics of the tasks and the way the tasks are organized in the textbooks and the workbook in accordance with the 2007 revised mathematics curriculum; comparing with the function section before and after the amendment. Researchers examine whether the textbook and workbook were accomplished the purpose with "cognitive expectation", "level of cognitive demand", "and "response types". Researchers revised framework of [Son, J. W. & Senk, S. (2010). How reform curricula in the USA and Korea present multiplication and division of fraction. Educ. Stud. Math 74(2), 117-142] to make them suitable for the function section at the seventh grade.

In this study, the analogies in the chemistry domain of middle school science textbooks developed under the 2007 revised National Curriculum were analyzed. A total of 235 analogies were found in 27 middle school science textbooks analysed, which means that one analogy per 10 pages was used on average. The number of analogies found in each textbook considerably varied depending on both publishing company and chemistry domain. Functional analogies, verbal and pictorial analogies, analogies with abstract target and concrete analog, enriched analogies, everyday contexts analogies, student-centered analogies, and analogies with low systematicity were frequently used. On presenting the analogies in the textbooks, the term analogy and description about the limitations of the analogies were rarely mentioned. In comparison with the analogies in the science textbooks developed under the 7th National Curriculum, the frequency of analogies per page was increased. There were positive changes in the aspects of representation, extent of mapping and artificiality. No differences, however, were found in the patterns of the other aspects.

The purpose of this study is to assist understanding the integrated subjects and to obtain implications required on the actual operation of curriculum by analyzing content elements and basic inquiry activities in the revised "wise lift" curriculum 2007. The result of this study is as follows. First, the formation of elements in contents of "wise life" deals with the passage of time based on changing seasons, myself and family in the 1st grade and the concept of space based on home and a village in the 2nd grade. Six main subjects and twelve activity subjects are presented per each grade. Second, number of activity subjects and content elements are reduced as compared with 7th curriculum so that the responsibility of operating classes based on activities is reduced and the purpose of rationalizing contents is somewhat fulfilled. Third, eliminating a relevant domains decisively when presenting the activity subjects assures the identification and purpose as the integrated subject focused on inquiry activities. Fourth, the result of analyzing the course-relevance on content elements shows that the allotment per each domain and course is less considered but the relevance of social studies is higher regardless of non-course characteristics as the integrated subject. Fifth, according to the component ratio of basic inquiry activities, 'Observing' and 'Debating' were presented as the most essential activities, and 'Measuring' and 'Making' were relatively low. By considering characteristics of course requiring balanced and various experiences of inquiry activities, additional discussions are required on appropriateness of the component ratio. Sixth, 'Observing' was increased and 'Debating' and 'Making' were decreased on the main activities in this revised curriculum as compared with 7th curriculum.

The purpose of this study is to find historical paradigm shift of the environmental subject in Korean school curriculum. For the purpose, two research questions guided this study. First, we would like to find out the changes in environmental education curriculum by interpreting the Korean national curriculum. Second, we want to know about the paradigm shift of environment education in Korea. In this study, curriculum documents, teachers' guide books, textbooks, and other educational materials were used for literature review. The results are as follows: First, Robottom and Hart's frame of three paradigms in environmental education research, positivism, interpretivism and social criticism, was suitable in interpreting curriculum. Second, the curriculum of environment subject has substantially changed from 6th to 2007 revised curriculum. Third, while the 6th curriculum was strongly affected by the positivism and education 'about' the environment, the 7th curriculum had been influenced by the interpretivism and education 'in/through' the environment, and the 2007 revised curriculum is under the influence of the education 'for' the environment and social critical paradigm.

The purpose of this study was to analysis the home economics education curriculum from the first national curriculum to the 2015 revised curriculum using text mining techniques used in big data analysis. The subjects of the analysis were 10 curriculum texts from the first national curriculum to the 2015 revised curriculum via the National Curriculum Information Center. The major findings of this study were as follows; First, the number of data from the 4th curriculum to the 2015 revised curriculum gradually increased. Second, as a result of extracting core concept of the curriculum, there were core concept words that were changed and maintained according to the curriculum. 'Life' and 'home' were core concepts that persisted regardless of changes in the curriculum, after the 2007 revised curriculum, 'problem', 'ability', 'solution' and 'practice' were emphasized. Third, through core concept network analysis for each curriculum, the relationship between core concepts is represented by nodes and lines in each home economics curriculum. As a result, it was confirmed that the core concepts emphasized by the times are strongly connected with 'life' and 'home'. Based on these results, this study is meaningful in that it provides basic data to form the identity and the existing direction of home economics education.
