2007 Curriculum Revision adopted new Inquiry Activities in mathematical textbooks. So it is critical to analyze the problems of actual application of Inquiry activities in the classrooms. For this purpose, we analyzed the Inquiry activities of Measurement Area of the textbooks and find the appropriate solutions. Secondly, we develop the reorganization materials to fix and solve the existing problems found in the previous problem analysis, and apply the development materials and examine the effects afterwards. The results of the survey indicated that most of teachers are well aware of the importance of Inquiry Activities. However, many teachers answered that Inquiry activities does contain neither diverse strategic approaches nor solutions accommodating with various learning levels of students. The most difficult points to educate Inquiry Activities are that it is difficult to teach students based on individual learning level and that activities consist of mainly short answers that makes it difficult to do in-depth Inquiry Activities. Analyzing Inquiry Activities in the textbook shows that Inquiry Activities in some chapters were constructed as simple sentence questions or presented with the solving process in the questions themselves. The following application classes were implemented by partially taking advantage of the newly developed reorganization materials. Then, the effects were measured by before and after questionnaires, the survey to teachers, and the results of activities. The reorganization materials were effective at arousing the curiosity from students as well as enabling the natural ability-level driven classes.

Many questions have been raised about mathematical education in vocational high schools. In this study, we have reorganized a typical mathematics textbook used in vocational high schools to check if this reorganization could be effective in students' learning. We also examined students'feeling about this. Contrary to our expectations, we could not find any noticeable differences in students' achievement. But we found that students with a high grade tend to major in mathematics- related subjects.

The 2007 revised social studies curriculum emphasizes history education in particular. Thus the contents of the history section previously scattered through 3rd, 4th, 5th and 6th grades are now integrated into the first and second semesters of the 5th grade in elementary social studies. Therefore, this research intend to gain insights that could be used as a reference when making next social textbooks by analyzing social textbooks of the 7th and the 2007 revised curriculum. The conclusions of comparative analysis on social textbooks of the 7th and the 2007 revised curriculum are as follows: The textbook units according to the 2007 revised curriculum were a reorganization of the contents from the 7th's 6th grade 1st semester contents per unit in a chronological flow. Meanwhile, the topic was introduced to supplement historic contents afresh. The 2007 revised curriculum focused on the life history, cultural history, personal history.

The purpose of this study is to obtain implications for the improvement direction of astronomical education methods and development of educational materials or software. In connection with the 5th grade 1st semester elementary science 'Solar System and Stars' unit, elementary pre-service teachers were given a reorganization task to compare the relative distances from the sun to the planets, and then this was analyzed. Pre-service teachers are 11 male and 19 female students in the second year of the music education department at the elementary school teacher training university in B city. The implications of the study results are as follows. First, the 'distance comparison activity using a roll of tissue paper' is suitable for simply comparing the distances from the sun to the planet, but it has limitations in allowing students to experience the vastness of the solar system or inducing student participation-centered classes. Second, it is necessary to develop software materials for elementary school students that can simultaneously reflect the size of the planet and the distance to the planet that can be applied indoors, and also experience the vastness of the solar system, as well as a wide learning space. Third, textbook materials for students have an important influence on the class design of pre-service teachers.

The purpose of this study was to investigate how educational experience (teaching experience, experience participating in the Teacher Learning Community, curriculum training experience, and innovative experience working in school) of elementary school teachers affects the recognition and execution of curriculum and textbooks. For this purpose, the results of a questionnaire survey for elementary school teachers were analyzed by performing T-tests, One-Way ANOVA, correlation analysis, and regression analysis. The results were as follows. First, according to the teacher's educational experience, there were statistically significant differences in the recognition and execution of curriculum reorganization, and the recognition and dependence on textbooks. Second, there were statistically significant correlations among such variables as recognition and implementation of curriculum reorganization, and the recognition and dependence on textbooks. Third, the teacher's educational experience had a significant impact on curriculum reorganization and the dependence on textbooks. Curriculum restructuring in elementary schools is not an end in itself. What is also needed is to find and implement the best class plans for promoting the .meaningful growth and development of elementary school students. This study suggests that the dependence on textbooks should be lowered and the curriculum should be actively reorganized, and teachers should develop their expertise based on extensive educational experience.

This paper aims to analyze English vocabulary of the North Korean textbooks diachronically using the constructed English textbook corpus. The North Korea English textbooks attained from Information Center on North Korea of the Ministry of Unification are divided into before and after Kim Jong-Il era for the year of 1996 in which the curriculum revision has been conducted. They are stored as text files to analyse vocabularies using WordSmith Tools 7.0. The vocabulary size of the revised textbooks increased after the curriculum reorganization, but the number of vocabulary types and vocabulary diversity decreased. After the curriculum revision, it was found that lots of vocabulary related to the establishment of the Kim Jong-Il system appeared as the keyword. It was also found that some vocabularies reflected the economic and social life of North Korea. In addition, through comparison of the 100 high-frequency word list and keywords, it can be concluded that the vocabulary of the English textbooks of North Korea is gradually changing into communicative contents from contents related with written language.

The study aims to investige how Soupjin, military training has been changed in early Joseon Dynasty. The conclusions are following these. First, Jin means military marching or attacking the enemy and Jinbeop means how to make Jin or traning but now Jinbeop indicates textbook of Jinbeop rather than practing it. Second, publishing Owijinbeop is completed as a result of continuous series of Jinbeop textbook and Owi systems are built up by military construction reorganization. Third, the total number of articles is 268 from Taejo to Seonjo in early Joseon Dynasty. They are divided into different parts according to kings. Forth, Taejo, Taejong, Munjong, Sejo, Yejong and Jungjong are the kings who take the lead of Jinbeop training directly. Among them Munjong and Sejo are highly considered that they edited and revised Sinjinbeop and tried to unify military organization. Besides Jungjong discussed Jinbeop textbooks which are published by prior kings and even make them be practiced. But after Imjinwaeran, Seonjo accepted the book Gihyosinseo by Cheokgyegwang in China and transformed our Jinbeop for protecting the country. Firth, We found that Hyangmyung and Jintoigyjak had been focused from Sejo to Jungjong. Because in this period Joseon had to find the way to protect the country from north Yeojin, But after Imjinwaeran Seonjo introduced Cheokgyegwang's Jeolgangjinbeop in China because of Japanese attacks.

The purpose of this research is to improve the writing ability of students by an ideal test model of English writing based on strategies of procedural learning stages enhancing the level of students' writing ability. Assessment of writing in the field of English education has been limited so far to very restricted areas with no appropriate scientific scrutiny. Assessment is really meaningful only when it exactly estimates the ability of students. Since English writing competence has become indispensable in this era of global village, writing instruction should be most emphasized. The most forceful method of busting writing instruction is to utilize the so-called washback effect of testing. So, to develop a good test model of writing, the first thing that is required is to inspect writing strategy in steps and, then, testing itself. First of all, analyzed with a special reference to the 6th high school English curriculum were the goals and contents of the syllabus reflected in one kind of junior high textbook and eight different kinds of senior high textbooks. Then questionnaires on the whole area of writing and tendencies of English writing classes were given to 100 English teachers, 300 students. The results of questionnaires were statistically analyzed. Then, some suggestions and opinions about the questioning method were made: the procedural strategy in steps, English writing instruction and test model of assessment were applied to the syllabus referring to teaching plans. On the bases of the results of the questionnaires, three pretests and a final test of English writing were administered to verify the effect of enhanced English writing competence which had been gradually promoted and, through the promotion, produced the test criteria of English writing. In conclusion, guidance and evaluation of English writing through in steps are really indispensable to increase student's practical ability and, accordingly, we are in need of the development of a testing method of useful writing practiced in school class above anything else. So, it is necessary to further the study on methods to assess writing ability on the bases of participation and fluency of students with their keen interest in English. Also, to intensify the effect of the test model, more accommodating reorganization of syllabus is required in our education. For instance, we need a flexible operation in organizing time units from the current 50 minutes to 100-130 minutes.

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.
