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.

In this paper, we analyzed the utilization trend of technology in the secondary mathematics textbooks based on the 6th, 7th and 2007 revised mathematics curriculums in Korea. We analyzed 30, 60 and 90 mathematics books based on the 6th, 7th and 2007 revised mathematics curriculums respectively. The analysis focused on three aspects of using technology, i.e., contents areas in which technology used, technological tools and programs used, and methods of using technology in teaching and learning mathematics. The results shows that the frequency of using technology in mathematics books has been increased as mathematics curriculum has been revised. In the mathematics books based on th 6th curriculum, only 25 scenes were found, but in 7th and 2007 revised curriculum 248 and 355 scenes were found. In the 6th curriculum, calculators and graphing calculators were used mainly, but in the 7th and 2007 revised curriculum many kinds of technological tools and softwares were used including CAS, dynamic geometry software, spreadsheets, programming language, and the Internet. Especially the internet was used frequently in the 7th curriculum. And the methods of using technology has been diversified as time passed. In the 6th curriculum, the technology mainly used for introducing technology and simple calculation, but in the 7th and 2007 revised curriculum the technologies and software were also used for understanding mathematical laws, principles and concepts and students-centered exploring the mathematical properties.

The purpose of this study is to find the point for improvement through the comparative analysis of the 2007 & 2009 revised science curriculum, and the NGSS of the United States with Bloom's revised taxonomy. The results of the analysis confirmed that the revised curriculum in 2009 compared to the revised curriculum in 2007 has expanded the type of cognitive process and knowledge, which promote a higher level thinking. However, the revised curriculum in 2009 has been biased to the type of specific cognitive process and knowledge in cognitive process dimension and knowledge dimension as compared to the NGSS of the United States. In the revised curriculum in 2009, the type of cognitive process such as 'analyze,' 'evaluate,' 'create,' and the type of knowledge such as 'meta-cognitive knowledge' have been treated inattentively. In addition, through comparative analysis, it was identified that the type of cognitive process and knowledge that were neglected in achievement standards were not dealt with in the learning objective of teachers' guides, either. The revised curriculum should consist of achievement standards in comparison to the previous curriculum to reflect better the goals of science education. Therefore, it is necessary to create an achievement standards including various types of cognitive processes and knowledge by improving the method of statement of achievement standards of science curriculum.

The purpose of the study was to figure out elementary school teachers' Stages of Concern(SoC) between senior teachers and new comers to integrated units of integrated curriculum which was revised in 2007 and applied in 2009 by using CBAM. Seventy-four home-room teachers in elementary schools took part as participants. For data collection, as Hall and Hord suggested in 2005, Questionnaire of Stages of Concern was used. Profiling of teachers' concern and one-way ANOVA were employed in data analysis. In the results, 55% of the teachers were in the stage of Awareness. In the stage of Informational, 22% of the teachers were appeared. Most of elementary teachers' concern about integrated units was closed to indifference of self-interest level. The difference of concern between senior teachers and others will be illustrated as findings. The results of the study provided that factors which influenced teachers' concern about the curriculum. Physical factors such as a curriculum guideline or on-line system to access boarder-cross curriculum influenced teachers' concern. Little intervention about the boarder-cross curriculum appeared in elementary schools. The authors of the study suggested to emphasizing the roles of facilitator for the revised curriculum.

If the philosophy of the curriculum is changed when the curriculum is revised, discussion about knowledge viewpoints in the changed philosophy is needed. The purpose of this thesis is to analyze elementary mathematics textbooks(EMT) based on the perspective of constructivism knowledge as basic philosophy of the 7th curriculum and the 2007 revised curriculum and to present aim of textbooks development through the results. According to the results, the number and operation units of 1st and 2nd grades of EMT compiled according to the 7th curriculum and the 2007 revised curriculum didn't reflect the perspective of constructivism knowledge as the philosophy of the curriculum. From the analysis, EMT were not composed so as to agree the perspective of constructivism knowledge that emphasize concepts, conceptua1 principles, variety, integration.

This study aimed to investigate how science teachers perceived major features of the 2007 revised science curriculum and implementing them in classes. The 2007 revised science curriculum included critical features such as creativity, open inquiry, science writing, discussion and STS. In terms of necessity, clarity and complexity of those features for curriculum implementation, teacher perceptions were examined. Particularly with regard to open inquiry assigned 6 class periods per semester as one of the critical features of 2007 revised science curriculum, we asked teachers how they would prepare and implement the technique in their teaching. In results of this study, science teachers agreed on the necessity and importance of those major features of the 2007 revised science curriculum, including creativity, open inquiry, science writing, discussion, and STS. However, they were not clear on how those would work in their classrooms and expected various impediments. Open inquiry was specifically perceived as most negative in its implementation with the mention of various complex reasons. Based on findings in this study, we proposed the 'Dual Action Research Model' for curriculum implementation. It tries to explain how curriculum is implemented in classrooms and diminish the gaps between curriculum developers and teacher users by means of leading teachers to understand the curriculum meaningfully and implement their teaching based on this understanding.

This study aims to investigate the research trend of elementary environmental education. Thus, author keywords were extracted from a total of 197 academic these related to elementary environmental education during two different periods when detailed goals were applied to the 2007 and 2009 revised curriculums respectively, and then this study analyzed the network of author keywords. The results of this study can be summarized as below. Firstly, as a result of analyzing the frequency of author keywords from academic theses related to elementary environmental education, this study discovered 369 author keywords from the period when detailed goals were applied to 2009 revised curriculum. Out of them, it was found that the keyword, 'climate change education', showed the highest frequency, followed by 'environmental literacy' and 'environmental perception', except such central keywords as 'environmental education' and 'elementary school student'. From the period when detailed goals were applied to the 2007 revised curriculum, a total of 394 author keywords were discovered, and the keyword, 'environmental literacy', showed the highest frequency, followed by 'environmental perception' and 'ESD (education for sustainable development)'. Secondly, as a result of analyzing the network of author keywords, this study found out that in the total number of network connections, average connection degree, density and clique, the period when detailed goals were applied to the 2007 revised curriculum was somewhat higher than the period when detailed goals were applied to the 2009 revised curriculum. As a result of analyzing the centrality of author keywords, this study found out that during both the periods, 'environmental perception' and 'environmental literacy' were high in degree centrality and betweenness centrality, except such central keywords as 'environmental education' and 'elementary school student'. As a result of analyzing the components of author keywords as sub-networks, this study discovered 9 components from the period when detailed goals were applied to the 2009 revised curriculum and 6 components from the period when detailed goals were applied to the 2007 revised curriculum. During both the periods, the largest component was composed of keywords high in degree centrality and betweenness centrality.

The aims of this research were to analyze and compare verbs in the contents of the 7th, 2007, and 2009 revised national curriculum for elementary and middle school science. After the investigation of 1383 verbs in description of achievement standards and inquiry, we found that 'to know'(15.0 %) in elementary school and 'to understand'(24.2 %) in middle school were the most frequently used ones, totally in these three curriculums. In the 7th national curriculum, frequently used verbs in elementary school were ones related with inquiry such as observation, investigation and so on though 'to understand' had the most common verbs. Secondly, 'to explain' ranked top among verbs in the 2007 revised national curriculum. It showed some possibility of influences of the discussion-oriented situation at that time. Finally, however, in 2009 revised national curriculum, 'to know' and 'to understand' occupied the first and second portion of the verb distribution. In addition, 'to understand' and 'to observe' were used evenly through three curriculums but the portions of 'to know' increased through curriculum revisions. Some implications and discussions were also added with suggestions for further researches.

The proliferation of bioinformatics in modern biology marks a modern revolution in science that promises to influence science education at all levels. This study analyzed the contents of standards in the 7th and 2007 and 2009 revised high school biology curricula and compared the contents, amount and the presentation styles of bioinformatics with those of biotechnology in biology textbooks. In result, first of all, there are some vague expressions about biotechnology and bioinformatics in the 7th and 2007 revised curriculum. There is a clear expression about biotechnology in 'life science I' and 'advanced biology' of 2009 revised curriculum. Second, more biotechnology is introduced than bioinformatics in 'science', 'biology I', 'biology II', 'life science I' textbooks. Third, in 'biology for high class' textbook, amount of biotechnology contents in the 2007 revised curriculum didn't increase. An more effort to introduce bioinformatics to science high school student is needed according to revising curricula.
