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.

Increasing the problem solving power in school mathematics is the most important task of mathematics education. It is the ultimate goal of mathematics education to help students develop their thinking and creativity and help solve problems that arise in the real world. In this study, we investigated the contents of problem solving according to mathematics curriculum goals from the first curriculum to current curriculum in Korea. This study analyzed the problem-solving contents of the mathematics textbooks reflecting the achievement criteria of the revised curriculum in 2015. As a result, it was the first curriculum to use the terminology of problem solving in the mathematics goal of Korea's curriculum. Interest in problem solving was most actively pursued in the 6th and 7th curriculum and the 2006 revision curriculum. After that, it was neglected to be reflected in textbooks since the 2009 revision curriculum, We have identified the problems of this problem-solving instruction and suggested improvement direction.

The new national K-12 Information subject curriculum which will be effective in year 2010 includes algorithm and programming sections. Programming languages in K-12 are more effective the Educational Programming Language (EPL) than general language, because it focuses on developing problem solving ability rather than training a programmer. Therefore, it is necessary to study for suitable EPL in Korean K-12 curriculum. In this study, we studied and analyzed various types of EPLs available and strategies to apply them to the new national curriculum. First of all, we chose 26 educational programming languages and analyzed their characteristics and functions. Also, we investigated associations between key factors of the new Information curriculum and each language and suggested a proper language for their students' level. Finally, we considered possible problems and suitability to Korean K-12 students. The result of this study help us to choose what is the proper EPL and to consider applicability and criteria of EPLs.

Both curriculum and textbooks play an important role in the process of didactical transposition from mathematics as a science to school mathematics. The 2009 revised national curriculum for mathematics introduced the system of grade-band, so its achievement criteria for mathematical contents tend to be addressed more and less generally in the curriculum. We need to investigate whether the achievement criteria were applied meaningfully in elementary textbooks for mathematics. This study aims to recognize the connection between the curriculum and the textbooks and make a suggestion for composing the following curriculum and its textbooks. To do this, we analyzed the mathematics textbooks for 1~2 grades in relation to the mathematical contents as per reconstructed one of curriculum achievement criteria, the mathematical terms and symbols, and the mathematical processes -mathematical problem solving, mathematical reasoning, mathematical communication. Based this analysis, futhermore, this study includes some didactical discussions and implications for development of mathematics textbooks in 3~4 and 5~6 grade-bands.

This study is aimed at finding some drawbacks of current elementary mathematics textbooks and to give suggestions for ongoing new textbooks according to 2009 revised curriculums, by comparing and analyzing Korean textbooks and chinese textbooks of People's Education Press. The areas are confined to number concepts, addition and subtraction for comparative analyzing. The results are followings: Korea textbooks have more verbal expressions, designated instructive activities for students to do, similar algorithm applied for enlarging mathematical concepts, bigger number concepts and number usage of operations, and monotonous number sense activities. Therefore Korean textbooks, compared to China's, is more weaker in areas such as encouraging student's interest, in challenging mathematics, and in forming fundamental mathematical concept.

In this study, MBL experiments in the Korean secondary science textbooks and chemistry textbooks under the 2007 and the 2009 curriculum revision were analyzed in terms of curriculum revision era, grade, context of experiment in the textbook, field of science, topic, sensor, and publisher. As a result, 25 MBL experiments were found in the science textbooks under the 2007 revision, and 29 experiments under the 2009 revision (19 for middle school textbook and 10 for high school textbook). MBL experiments in middle school textbooks were not increased after curriculum revision while those in high school textbooks appeared for the first time. Most of them were in the textbooks for grade 7 and presented as an essential experiment rather than optional one. Motion sensor and temperature sensor were used most frequently, and oxygen sensor and carbon dioxide sensor were followed. In aspect of publishers, a frequency of MBL experiment was decreased in most textbook and some publishers didn't include MBL experiment at all. Based on these results, educational implications were discussed.

As a main body of a curriculum, a set of sentences stating mathematical contents plays an important role in teaching and learning mathematics. The contents sentences in the $7^{th}$ version, the 2007 version, and the 2009 version of elementary mathematics curricula were analysed. The elementary mathematics curriculum consists of about 200 contents sentences. The final endings of those sentences are the type of ability such as "to be able to ~". The elementary mathematics curriculum would be managed systematically by disassembling and restructuring those contents sentences. We should state students' activities more concretely by varying the final endings in the curriculum.

The purpose of this study was to compare the duplication problem of achievement standards between science and other subjects in the 2009 Revised National Curriculum and to search for solutions and implications for this problem. From the results of this study, we found that the achievement standards of practical arts, social studies, physical education and ethics were overlapped with science's ones. The duplication of content elements for 'our body and health', 'living things and environment', 'biodiversity' and 'natural disaster' categories was not high, that is, their achievement standards were relatively well-differentiated and reflected the intrinsic characteristic of each subject under common topics. But, in case of 'reproduction and development' and 'world of technology' categories, the problem of duplications was serious. In order to cope with this problem, we need to consider solutions such as merging or integrating the achievement standards of related subjects. The relevant experts should conduct in-depth discussion and negotiation, and develop achievement standards more consistent with the identity of each subject.

This study is related to reinforcement of the continuity between Nuri curriculum and elementary mathematics curriculum emphasized by 2015 revised national curriculum. Considering that teachers tend to rely much more on textbooks than on curriculum, we analyzed the continuity between math-related activities of Nuri manuals for teachers and the elementary mathematics textbooks and aimed to suggest several ways for securing the continuity based on the result of analyses. To do this, we compared and analyzed Nuri manuals (for ages three to five) for teachers and the first and second grade mathematics textbooks in three aspects: mathematical contents, mathematical terms and symbols, and mathematical processes. We adopted the same analysis framework including continuity, discontinuity and reverse continuity as the study on the continuity between Nuri curriculum and elementary mathematics curriculum. As a result, the results of analyses were revealed in three aspects, respectively. We also discussed the results and suggested some implications for securing the continuity of Nuri manuals for teachers and the elementary mathematics textbooks and for revising curriculum and its materials such as textbooks, workbooks or manuals for teachers.
