The purpose of this study was to analyze the reading materials in 7th curriculum and 2009 revised high school chemistry I textbook for identifying the problems of reading material presented in science textbooks and to investigate science teachers' recognition about utilization reading materials in science textbook. For this purpose, each four 7th curriculum and 2009 revised high school chemistry I textbook were analyzed according to the number of reading materials, the type of contents and the type of students' activities. In addition, the secondary school science teachers' recognition about utilization reading materials in science textbook was investigated. The results were as follows: First, anylizing reading materials in chemistry I textbooks showed that and the rate of reading materials were presented from 7.9 to 17.1% in 7th curriculum and from 20.6 to 28.2% in 2009 revised curriculum textbook. It implies that the rate of reading materials in 2009 revised textbooks increases more than those in 7th curriculum textbook. The result of analyzing the type of contents, 'life sciences' was the largest proportion with 34.3 % in the 7th curriculum chemistry I, but 'enrichment and supplement of knowledge' was the largest proportion with 23.7% in 2009 revised curriculum. Analyzing the type of student activities, only 13% of the reading materials in 7th National Curriculum textbook was found to be inquiry type, but 35% of the reading materials in the 2009 revised curriculum. appears to be inquiry type. It suggested that the curriculum objectives was reflected in the textbook. Second, investigating recognition of teachers' perceptions of utilization science textbooks, 67% teachers responded that they used the reading materials in their science class, but teachers who didn't use the reading materials was almost 33%. A large number of teachers responded that the reading materials associated with the real-life needed for integrated education and thought that the reading materials about 'life and science' should be included in the science textbooks.

Problem solving ability can be fostered by dealing with many different types of problems. We investigated how $5^{th}$ and $6^{th}$ graders who did not learn traditional algebraic methods might approach the word problems of simultaneous equations. This result reveals that the strategy of guess-and-check serves as a basis for elementary school students in solving simultaneous equations. A noticeable remark is that students used the guess-and-check strategy in various ways. Whereas some students changed a variable given in the problem step by step, others did in a sophisticated way focusing on the relation between two variables. Moreover, some students were able to write an equation which was not typical but meaningful and correct. This paper emphasizes the need of connections between pre-algebraic and algebraic solutions.

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.

In this research we diagnosed the actual status of the 7th National science elective curriculum and suggested a way to select and organize the content of the new science elective curriculum. The first science education reform was grounded in the structuralism where the structure of discipline was valued above everything else. On the other hand, the second science education reform suggested alternative interpretations of students' opportunity to learn, putting a brake on the structuralist thinking. According to the survey result, the majority of the science elective courses are in need for revision because the contents are overcrowded, too difficult in light of students' learning readiness, failed to draw students' interest in science, and are overlapped and repeated among the 10th grade science, high school science I and II. In particular, Earth Science II and physics II are the most unfavorable courses among students. Thus, we recommended a fundamental change be made in the new curriculum in addition to the optimization of the content. In this paper, we suggested 'topic-centered content organization' for the science elective course I, i.e., Physics I, Chemistry I, Biology I and Earth Science I that is designed for both science track and non-science track students. Since curriculum provides students with an 'opportunity to learn', a curriculum study should focus on what the 'opportunity to learn' is that students ought to be offered. Based on the result of this study, we recommended one way to select and organize the content of high school elective curriculum.

The purpose of this study was to analyze the STS (science-technology-society) contents in chemistry chapters of middle school science textbooks standardized by 7th national curriculum, and to investigate chemistry teachers' perception of STS education. This study was based on 8 essential elements in STS education suggested by Yager and 9 activities in SATIS (science and technology in society). The questionnaire and interview were used to investigate chemistry teachers' perception. As a result of this study, the average value of the STS contents in chemistry chapters of 7 kinds of middle school science textbooks was 22.4%, and the STS contents were preponderated to essential elements of science application and local and community relevance. And STS contents showed that science 2 textbooks were the most of all and in order of science 1 textbooks and science 3 textbooks. As a result of analysis by activities in SATIS, most activities were practice activity, problem-solving and decision making, and structured discussion. Chemistry teachers' perceptions of STS education were following. There were many responses that STS education was necessary for educational efficiency. On the other hand STS education was unnecessary because there were few effective teaching-learning method related with STS education. From these results, middle school science textbooks have to be complemented because 2 essential elements of the STS contents were preponderated in the science textbooks. And the teaching-learning method connected with STS education will have to be developed for the efficiency of STS education.

It has been criticized that there are discrepancy between 'general statements' of the curriculum and subject-matter curricula. The possible reasons for this are as follows: The developers of the general statements were educational curriculum specialists. These specialists were not good enough to develop general statements and guidelines of subject matter curricula reflecting the characteristics of science contents, to examine developed science curriculum, and to give feedback to science curriculum developers. Under the present curriculum developing system where curriculum is developed in ten months or less by the research team commissioned unpredictably and imminently, it might be difficult to develop valid and precise science curriculum reflecting the purport of the general statements and teachers' needs. The inadequacy of these curriculum development processes resulted in (1) inconsistent statement about the school year to be applied to differentiated curriculum, (2) abstract and ambiguous stating about the characteristics, teaching-learning and assessment guidelines of enrichment activities, and (3) failure to reduce science contents to a reasonable level. Therefore curriculum development centers should be designated in advance to do basic research at ordinary times, and organized into a cooperative system among them. Two years or more of developing time and wider participation of scientists are recommended to develop more valid and precise science curriculum. In addition, commentaries on science curriculum should be published before textbook writing begins.
