This study is to analyze the base of selection and feature of description on Korea-related content in Japanese curriculum(geography and history) and high-school geography textbooks. Japanese curriculum requires that there are two or three neighbor countries to be selected and their contents consist of life and culture and have to compare with those of japan in view of understanding and respect on similarity and difference. The content of physical environment is only dealt as factors influencing on life and culture because regional teaming of neighbor countries focus on it. Dok-do is described with conflict region in most of textbooks. But some textbooks describe Dok-do with territory of Shimane-Hyun in Japan or devide like japanese territory on the map. There are described han-gul(Korean language), confucianism, buddhism and christianity, han-bok(Korean clothes), rice and soup, bulgogi(Korean meat dishes) and scissors, spoon and chopsticks, ondol(Korean floor heater), etc. with the cases of specific Korean life and culture. And, exchange between Korea and Japan focuses on more cultural view increasing recently than political and economical view. Then Japanese high-school geography textbooks humanize geography because of they focus on life and culture and promote not only knowledge and understanding but also altruism and empathy because they focus on similarity and difference through comparison between neighbor country and Japan. This shows how to able to practice regional teaming in globalization and multicultural society.

The purpose of this study was to find out the effectiveness of metacognitive instruction model on the changes of science concepts, when it was applied to 6th grade students. To do this, students were tested with the achievement of molecules and molecular motion concepts and metacognitive self-regulation test as a pretest Based upon metacognitive instruction model and student's conception, instruction program were developed. This metacognitive strategy Program was applied to the experimental group and expository teaching was applied to the comparison group (followed the order and method in authorized science textbook and teachers handbook). When planned lessons were finished, students were given a post-test to find conceptual change. After six months students were given a test again to find retention effect. There was a significant difference in conceptual change and retention between comparison group and experimental group by treatment at p< .05 level, The difference between comparison group and experimental group was especially significant, when the situation of test item wasn't similar to that of the textbook Metacognitive instruction model was more effective to high group than low group in metacognitive self-regulation level on conceptual change and retention. So the metacognitive strategy Played an important role in conceptual change and retention. And we can recognize that the students who take part in the metacognitive lesson can apply the corrected concept to the other concrete situation because they can understand new concept accurately by metacognitive strategies. And we can guess that high group in metacognitive self-regulation level can team metacognitive strategy easily but relatively low group student have some trouble in learning new strategy.

The purpose of this study is to analyze the teaching of statistical graphs according to elementary mathematics curriculum. To do this, we set up three research questions as follows. First, what is the change in achievement standards related to the teaching of statistical graphs in elementary mathematics curriculum? Second, what is the change in the teaching of the drawing of statistical graphs in elementary mathematics curriculum? Third, what is the change in the teaching of understanding of statistical graphs in elementary mathematics curriculum? For the first research question, we analyzed the achievement standards related to the teaching of the statistics of the 2015 revised curriculum from the first curriculum. For the second research question, we analyzed how to provide students with the opportunity to draw graphs(number of drawings) and whether to present the basic frame of the graphs(frame provided). For the third research question, we analyzed questions in the textbooks based on the graph understanding; 'reading data', 'finding the relation between data', 'interpreting data', 'understanding the situation'. As a result of the analysis, the achievement standard in the curriculum has changed in the direction of fostering statistical thinking, and it has been changed to emphasize the interpretation of the graph so as to make the graph drawing easy. However, 'interpreting data' and 'understanding the situation' were still lacking.

In this study, a method for an integrated flood risk mapping was proposed that simultaneously considers the flood inundation map indicating the degree of risk and the disaster vulnerability index. This method creates a new disaster map that can be used in actual situations by providing various and specific information on a single map. In order to consider the human, social and economic factors in the disaster map, the study area was divided into exposure, vulnerability, responsiveness, and recovery factors. Then, 7 indicators for each factor were extracted using the GIS tool. The data extracted by each indicator was classified into grades 1 to 5, and the data was selected as a disaster vulnerability index and used for integrated risk mapping by factor. The risk map for each factor, which overlaps the flood inundatoin map and the disaster vulnerability index factor, was used to establish an evacuation plan by considering regional conditions including population, assets, and buildings. In addition, an integrated risk analysis method that considers risks while converting to a single vulnerability through standardization of the disaster vulnerability index was proposed. This is expected to contribute to the establishment of preparedness, response and recovery plans for providing detailed and diverse information that simultaneously considers the flood risk including social, humanistic, and economic factors.

The purpose of this study was to develop experimental modules that would enhance science the process skills of secondary school students. The modules were composed of real-life materials on the subjects of light, movement, force, water, and heat. Each module consisted of four to six activities, and provided student worksheets and teacher guides. Physics teachers were invited to a workshop specially held to identify whether these modules would befit the improvement of student science process skills. A majority of the teachers believed the modules to be valuable instructional materials which might enhance student science process skills in the Korean secondary school science classes.

산림관리에 있어 공동체는 중심에서 풀-뿌리단계로 관심을 받아왔다. 베트남에서, 공유림은 오랜 기간 산림에 의존하고 있는 서로 다른 공동체의 존재 그리고 종교와 긴밀히 연결되어 있다. 지난 몇 년 동안, 지속가능한 산림경영의 필요성에 기초하여, 몇몇 지역 공동체는 산림 또는 임지를 마을과 가구를 포함하여 산림에 대해 소유권을 가진 지역공동체에 할당되었다. 게다가 공동체는 또한 산림을 보호, 천연갱신과 신규조림 등 정부기구의 프로그램에 참여하였다. 산림관리에 근거한 지역공동체의 경험은 경제-사회적으로 적합한 산림관리 모델로 이것은 베트남의 서로 다른 민족의 전통관습에 따른다. 그러나 법적인 면에서, 지역공동체는 아직 산림 또는 임지에 연결된 실체로 인식되지 않고 있다. 공동체 산림관리의 두가지 형태는 (i) 그들에게 속한 산림과 임지를 공동체가 직접 관리하는 경우와 (ii) 공동체가 국가기관이 소유한 산림의 보호와 조림에 참여하는 경우이다. 이 논문은 공동체 산림관리에 대한 현재의 상황, 잠재력, 경향 및 이슈를 명확히 하여 정책담당자의 이러한 산림관리에 대한 이해를 돕는 데 있다.

The purpose of this paper was to analyze the example spaces related with the concepts of triangles in the 2nd grade Korean elementary mathematics textbooks, investigate the meaning of example spaces, and suggest the implications to teaching and learning geometrical concepts in the elementary schools. Mathematics textbooks are usually major materials in teaching and learning mathematics in Korea, and the content of the textbooks affects the quality of teaching and learning in the classroom. The results of the study showed that the Korean elementary textbooks provided examples with limited example spaces concerning the concepts of triangles. The researcher suggested that we should provide rich examples spaces, encourage learner-generated example spaces, and strengthen the connections of examples between in textbooks and in the classroom.

This research intends to give a practice of mathematics lesson-critique and some perspectives on a mathematics lesson in the elementary school level. We carried out a mathematics lesson-critique on a lesson chosen as a good lesson by a local educational district in Korea. The main themes of mathematics lesson-critique were the reconstruction of lesson models, the pursuit of relational understanding, the activation of mathematical communication, and the didactical transformation by a in-service teacher. Meanwhile we confirmed that we need to discuss the properness and adequateness of contents about division of natural numbers given in the elementary mathematics textbook and teachers' guide according to the revised 2007 mathematics curriculum.

Understanding the concept of definite integral is based on understanding the concept of mensuration by parts. However, several previous studies pointed out the difficulty on teaching the concept of mensuration by parts. The paper provides some didactic strategies which help teaching the concept of mensuration by part. To teach the concept of definite integral, in the high school curriculum, the relation between definite integral and series is dealt with. However, the paper suggests that importing the concept of series is not indispensable to teach the concept of definite integral. It is proper that definite integral is taught as limit of particular sequence not series.
