This study analyzed the visual images covering 'weather' and 'weather forecast' in elementary science textbooks from the Syllabus Period to the 7th national curriculum from the socio-semiotic perspective. The results showed that most of the visual images were 'realistic' which were descriptive of real world phenomena. This means that most of the visual images in elementary science text were familiar to students in every curriculum period. The power relationship in communication between images and students was very complex. The visual images in elementary science textbooks include few geometrical and alphanumeric code in every curriculum period. This study provides a new framework to interpret amount of information, functions of information, structures, and social meanings of visual images. It could be also a beginning stage to introduce the socio-semiotic perspective into choosing visual images for next science textbooks.

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.

This study was intended to suggest the desirable direction in the 7th national curriculum revision through the illustration analysis of the elementary science textbooks in the 6th national curriculum. The analysis system was composed of two categories, (1)the kind of illustrations (2)the .ole of illustrations The kind of illustrations was divided into five subcategories such as photograph, pictures, illustrations, cartoons and diagrams. And the role of illustrations was divided into four subcategories such as motive induction, guidance for experimentation, the presentation of data and the results of experimentation. Each sentence in the textbooks was considered as an analyzing units. The frequency and percentage of each category were counted and the rates were calculated. The findings could be summarized as follows: 1. The illustration in the primary science textbooks was mostly composed of photographs (87.1%). 2. The examination of the role of illustrations showed that the presentation of data was 46.2%, the guidance for experimentation 38.4%, the results of experimentation 8.6% and the motive induction 6.8% respectively. 3. In the domains of physical and chemical science, the role of guidance for experimentation was emphasized. But the biological and earth science domains showed high tendency of the presentation of data.

The present study was carried out to analyse the frequency(%) for five kinds of inquiry context elements for six kinds of the high school science textbooks in the 7th curriculum. All the elements was classified into three process achievement level such as the basic, supplementary and further level introduced firstly in the 7th curriculum. Five elements of the inquiry context categories appeared as pure scientific context(61.8%), everyday context(22.2%), natural environmental context(7.7%), techno-industrial context(5.9%), and social context(2.4%) in the basic, supplementary and further level. Social context wasn't appeared in the supplementary level. In five elements of inquiry context, total elements appeared 7,139(85.5%) kfrequencies in the basic level and 691(8.1%) frequencies in the further level. However total elements appeared 529(6.4%) frequencies in the supplementary level. The kinds and frequencies of the elements for the inquiry context suggested in the basic level were more than those in the supplementary and in the further level. The social context was not appeared in the supplementary level. However five inquiry context elements were all appeared in the basic and further level.

The research aimed to compare science curriculum between Korea and Israel and find out characteristics of science curriculum in Israel at middle school level. The middle school 'science' of the 7th revised national curriculum in Korea and middle school 'science and technology' in Israel were compared. Among characteristics of the Israel curriculum of 'science and technology,' distinct ones are as follows: First, 'science and technology' was most highly emphasized with the largest number of time allotment among all subjects at middle school level in Israel. Second, the contents of 'science and technology' were classified into seven areas of 'energy and interaction', 'materials', 'organism', 'earth and the universe', 'technological systems and products' . 'information and communication',and 'ecosystems' rather than four areas of energy, materials, life and earth in Korea. Third, 'organism' was allocated with the highest number of hours among seven areas. Fourth, objectives of each content of 'science and technology' were divided into three categories: scientific aspect, technological aspect, and social value and objectives of each category were related to one another. This characteristic seems to stress STS, multidisciplinary, and interdisciplinary approaches in 'science and technology' in Israel. Such characteristics of the 'science and technology' education in Israel are likely to make significant contributions to establish human resources of highly developing science and technology including IT, BT, NT, ST in the future society. Reflecting upon the characteristics of 'science and technology' education in Israel, Korea might seek for ways to improve its national power based on science and technology through strengthening science and emphasizing science and technology contents among school curriculum.

The purpose of this study was to analyze the inquiry elements and inquiry activity of the inquiry area in chemistry I textbooks authorized by 7th curriculum. It was to confirm suitable reflection of the 7th science curriculum and to find educational suggestions of inquiry learning. It was found that the basic inquiry elements except measuring and classifying were well reflected on the textbooks. However, only several integrated inquiry elements and the inquiry activities were well reflected on the same textbooks. For the integrated inquiry elements, interpreting data was shown as the tower above the rest inquiry elements. In the analysis of inquiry activity, the numbers of experiment is placed almost half of all inquiry activities. The sum of two numbers of investigation and discussion is similar ratio to experiment but field trip and project are rarely or low ratio. As the integrated inquiry elements and inquiry activities were not balanced for various inquiry learning. It is suggested that learners be educated with complementary of these aspects in inquiry learning.

Students obtain most concepts through textbooks, and teaching-learning activities between teachers and students. Accordingly, if science teachers already have misconceptions they will inevitably affect students' scientific concept. This study found many problems in teachers' cognition on the concepts of nuclear radiation. Because 12th grade physics II is classified as an optional subject in the 7th curriculum, teachers have few chances to teach it and, more importantly, have difficulty in teaching it because of the need to prepare students for the university entrance examination. The concept of radiation must be taught correctly because of its emergence in the 'environment' unit of 10th grade Science. Finally, results from this study can help science teachers teach these difficult concepts more correctly. In addition, results can also be useful in in-service retraining programs.

The primary purpose of the study was to determine the appropriateness o the inquiry processes and its activities as described in Science 8's which were written according to the 7th National Science Curriculum. It was found that the basic processes were well reflected on the textbooks analyzed for the research. However, only a few integrated processes and the inquiry activities could be read on the same textbooks. Furthermore, a large majority of the inquiry processes and activities were not agreed with what the tasks and titles say. Especially, the none of as many as 216 experiments were not coincided with their titles' intentions. Also suggested in the paper were the implications of the results for inquiry-based science education in the Korean middle schools.

Geologic field survey is very important for the high school students who take the courses of earth science under the 7th earth science curriculum, however actually it is very difficult for the students to survey in the field because of long time and distance, and expenses. To overcome these difficulties, this study focused on developing the web contents and teaching-learning materials for virtual geologic field survey of the Songaksan and Jisagae area, Jeju island. The developed web contents were placed into three parts; main manu, sub manu and contents to help the learners flow-chart of the program easily. To overcome the weakness of existing textual web materials, some movable images and worksheets were provided for the learners, and the web contents were designed for the learners to experience as similar as the geologic field survey may let them do.

In this study, the texts of science textbooks of the past 20 years were collected in order to systematically carry out researches on scientific languages and scientific terms that have not been noticed in science education. We have collected all the science textbooks from elementary school to high school in the 6th curriculum, the 7th curriculum, and the 2009 revised curriculum, and constructed a corpus comprising of 132 textbooks in total. Sequentially, a raw corpus, a morphological annotated corpus, and a semantic annotated corpus of science terms, were constructed. The final constructed science textbook corpus was named K-STeC (Korean Science Textbook Corpus). K-STeC is a semantic annotated corpus with semantic classification and classification of scientific terms, together with meta information of bibliographic information such as curriculum, subject, grade, and publisher, location information such as chapter, section, lesson, page, and sentence, and structure information such as main, inquiry activities, reference materials, and titles. Throughout the three-year study period, a new research method was created by integrating the know-how of the three fields of linguistic informatics, computer science and science education, and a large number of experts were put in to produce labor-intensive results. This paper introduces new research methodologies and outcomes by looking at the whole research process and methods, and discusses the possibility of future development of scientific language research and how to use the results.
