The purpose of this study is to provide meaningful basic materials for organizing a science curriculum in future by analyzing the status and changes of contents about astronomical phenomena in textbooks according to the changes of the science curriculum of elementary school. A main target of analysis is science textbooks of elementary school in curriculums from 1st to 7th. For the analysis, the analytic frame based on contents in astronomy textbooks of teachers colleges and colleges of education was used. The result of the analysis is as in the following. First, astronomy accounted for average about 7% of all pages of textbooks in all of science curriculums. The 1st educational curriculum had the most learning quantity of 10.40%, and the 6th curriculum had the least quantity of 4.39%. These results show that astronomy was not a small part and was considered important in each science curriculum of elementary school considering that earth science accounted for 17-26% of all pages in elementary school science curriculum. Second, the things that have been dealt with in common in all science curriculums from 1st to 7th of elementary school are the shape of the earth, the rotation and the revolution of the earth, the occurrence of the seasons, the apparent motion of the sun, the status and motion of the moon, the movement of a star, the brightness and distance of a star, constellations, the sun, planets and others. These contents are expected to be dealt with continuously as basic contents to organize astronomy regardless of the changes of curriculum. Third, in science curriculum of elementary school, astronomical phenomena based on life experiences regarding the earth, the moon and the sun are mainly dealt with in the first and the second grade. Contents requiring principles-understanding and research are dealt with in the fifth and sixth grade. These results show that elementary school science curriculum dealing with astronomy reflects the developmental stages of students and considers principle of learning possibility.

This paper has analyzed the problem of the inequality unit in 7th National curriculum 8-Ga stage from the following points. First, in respect to the written questions of the inequality unit over every textbook of 7th National curriculum, how are they allocated according to subject matters and what are their weak points? Second. how many of them are related to the authentic daily life or other subjects and what kind of subjects are they? Third, what are the problems related to the authentic daily life situation or what are the problems that have some inter-sentential errors, and what kinds of measures for their improvement can be taken? In keeping with view points above, we have analyzed the contents in current 16 different textbooks on th basis of their subject matters and especially put the emphasis on the relation to daily life and other subjects. Consequently, we found there are many textbooks that do not include various subject matters and that can not be related to various other subjects. It is necessary to connect mathematics to various daily life matters and other subjects to improve students' creativity and to make students understand the practicality of mathematics.

The purpose of this study was to find out the operational status for the in-depth and supplementary class of middle school described in the 7th national science curriculum. To do this 455 students of 8th grade and 71 science teachers are administered questionaries which were developed to ask about whether or not execute the in-depth and supplementary class, the frequency of the execution, the way of forming groups and the contents of teaching etc.. The operation of the in-depth and supplementary class at middle school were prevented by following factors such as too many class time of teachers, overpopulation in class, insufficiency teaching materials and so on. Therefore, to solve these problems, various approaches should be adapted such as effective teaching method, teacher training program, specialized classroom, independent teaching on the part of teacher and so on.

The purpose of this study is to understand how the unit objectives and contents associated with environment are reflected on the 6 kinds of chemistry- I textbooks in the 7th curriculum and to present how to deal with the environmental education in chemistry- I. The results of this study are as follows. First, units associated with environment account for an average of 43.7% on chemistry- I in 7th curriculum. Second, contents of units related to environmental education on chemistry- I in 7th curriculum are environmental pollution(17.8%), environmental preservation and environmental pollution prevention(15.9%), environmental hygiene(12.2%), and any other things, Environmental pollution takes up a considerable part of environmental education. Third, the results for analyzing the objectives of chemistry- I in 7th curriculum show that Information Knowledge Awareness(34.0%) and Skill (29.9%) take up most parts. Fourth, Orientation (I) as analysis standard for objective of the units related to environmental education accounts for 10.2% of the total. It is clear that environmental education is carried out from STS point of view. In conclusion, environmental education in Chemistry- I focuses on fostering students' ability to apply the fundamental notion of chemistry to real life associated with environments. Therefore, it is necessary that environmental education in Chemistry- I should include value, attitude and participation and that improve students' ability to approach the environmental problem comprehensively.

In this study, the illustrations in 16 elementary science textbooks developed under the 2007 Revised National Curriculum were analyzed in the aspect of gender-role stereotyping, and the results were compared with those of the 7th National Curriculum. The frequencies of male and female who appeared on textbook illustrations were counted, and the types of activities and the characters of them were analyzed. Most pupils were found to be active, and female pupils appearing in the textbooks were more than male pupils. In all types of activities for pupils, the difference between male and female was decreased compared with that of the 7th National Curriculum. Male and female pupils were illustrated in learning activities with almost equal frequencies, but male pupils were still more frequently represented than female pupils in other activities. Gender difference in adults was increased and the difference was statistically significant. Gender difference in houseworks was not large, but the difference in outdoor activities was statistically significant. Especially, the jobs of adults were illustrated as male-centered, and scientists appearing in the textbook illustrations were also mostly male.

The purpose of this study was to understand on management and problems in the instruction of the subject of Technology and Home Economics, and to suggest the effective implementation schemes under 7th national curriculum guideline. The major results of this study were as follows. First, the teachers perceived the first reason why the subject of Technology and Home economics is being more unpopular is because the subject becomes not to include in the subjects of the national examinations for the Universities. Second. the teachers regarded the main problem in the present instruction of the subject of Technology and Home economics under 7th curriculum as the incorporation of the subject between Technology and Home economics, namely, no relation and organization with two majors. Third, which the teachers regarded as important tasks for effective management of the subject of Technology and Home economics were to lesser the extra charges except instruction related work of the teachers, and to increase the supply of the teachers itself.

The purpose of this study is to understand and compare the characteristics of the content organization system of three Environment textbooks currently used, and to examine its connectivity with the teaching & teaming methods included in the Environment subject part of the 7th Korean National Curriculum. For the analysis three Environment textbooks for middle school and their teacher's guide books by three companies. published(A, B, and C) The result of the taxonomic analysis showed that three Environment books had different steps to get to the lesson class unit in the way that A of six steps, B of five steps and C of seven steps. The amount of main text was different In the domains of'Human and Environment','Environmental Problems and its Counter-plan'and'Environmental Conservation'of three textbooks each. All of three textbooks had the biggest percentage in sub-domains of'Living Environment to Keep'and'Global Environmental Problem'in 'Environmental Problems and its Counter-plan'domain. Considering teaching & loaming methods all of three textbooks contained many activities as 55 in A, 66 in H and 91 in C. Among 9 teaching 8E teaming methods and others listed in the Environment subject part of the 7th Korean National Curriculum, the investigation method is most frequently used in all of three textbooks. The drama, the paly and the case study were used rarely as teaching & teaming methods in activities In the consideration of the content amount regarding academic fields, it was revealed that three textbooks overemphasized the aspect of natural sciences comparing the aspect of human & social sciences aspect as a whole. Generally the appendix section of all three textbooks were well organized to support the teaching and teaming activities in main text.

This study investigated how the 7th national elementary school science curriculum was implemented at science classrooms. Data from surveys with 140 elementary schools, 18 science classroom observations, and in-depth interviews with teachers were used to examine the characteristics of elementary school science instruction. Based on the data, I explored (1)how science curriculum is operated in terms of objectives, contents, methods and evaluation of school science, and (2)how student-centeredness and localization themes are reflected on the reconstructed school science curriculum. It was found that the degree of the reorganization of the national curriculum at the teacher level was minimal. And most of the elementary teachers followed the directions and contents of the science textbook and teacher's guidebook regardless of their own local situations. For most teachers, restructuring science curriculum meant reordering the sequences of the contents, and adding or deleting some units or topics. I also examined why elementary teachers have difficulty in reconstructing science curriculum at the classroom level. The necessity of curriculum reconstruction at the teacher level is also discussed.

This study was carried out to analyze inquiry area of the chemistry (II) textbooks which were published by the 7th curriculum. The study attempts to analyze the degree to which chemistry (II) textbooks reflected the guidelines of the 7th science curriculum and propose educational suggestions for the inquiry learning. The analysis of the inquiry area was carried out based on the suggested inquiry elements of the 7th science curriculum. Overall, for the analysis of inquiry elements, basic inquiry elements except classifying suggested by the 7th science curriculum were well reflected on the textbooks. However, for the integrated inquiry elements, interpreting data takes almost half of the total integrated inquiry elements. Other integrated inquiry elements except drawing conclusion and transforming data were reflected less than ten percent. Investigation was also reflected less than ten percent of all inquiry activity. And inquiry activities were limited in terms of variety with few projects and no field trip. The main essence of the 7th science curriculum is the emphasis on total inquiry learning through various integrated inquiry elements and inquiry activities for higher grade students. Thus it is suggested that teachers provide inquiry learning which can supplement the textbook.
