Decimal Fraction with a significant meaning is being treated for long periods, from elementary school to high school. It is necessary to consider in a course of guidance about various aspects of decimal Fraction first of all in order that student understand well about the concert of it. If you overlook guidance of various means of decimal Fraction, Previously learned number system is limited understand of Decimal Fraction concept or meaning of Decimal Fraction limited to the one is difficult to calculate the Decimal Fraction, even can weaken understand of Real Number. Accordingly, in this study, we would like to separate meanings of the Decimal Fraction, focusing on the role and function of the Decimal Fraction in various situations used the Decimal Fraction. Based on this, we analyzed and criticized how to introduce the Decimal Fraction in elementary school textbooks according to the 7th curriculum.

It has long been that the unit of oceanic salinity changed from permil (%o) to other unit. However, the middle-and high- school textbooks of science and earth science have still used %o as salinity unit that was defined a long time ago. The objectives of this study are to briefly discuss about the historical development of change in salinity unit and measurement techniques, to present differences between the salinity units of psu (practical salinity unit) and %o, and to address the need and validity for the correction of salinity unit in the textbooks. Twenty-seven kinds of textbooks based on the 7th National Curriculum were analyzed to investigate the expression of salinity unit and the definition of salinity. The results were compared with the usage of salinity units in the articles published in Journal of Korean Society of Oceanography from 1967 to 2008. The percentages by the use of %o were 96.3% in the text and 83.8% in the graphs or tables of the textbooks. By contrast, the scientific papers began to use psu from 1994 and then %o has seldom been used since 2004.

A web-based instruction program for the enriched course under the 7th Revised National Curriculum of Biology in Korea was developed and the application effects to learners were analyzed. For the development of the web-based instruction program, five topics of biology from the enriched courses through 7th to 10th grades in the middle and high school science textbooks were selected and modulated with interrogative sentences. Each topic of programs was divided into four activity sections according to the learners' activity procedures supplemented with explanations and evaluations. Each activity was hyper-linked to multi-layers and animations. Further, a virtual experiment was also developed and an evaluation section designed by Java Script was attached. Among five topics, one topic of 'Reproduction and development' at 9th grade level was selected to examine the effects on students' learning. Among 247 9th grade students in the research subject school, only 67 students were able to accessible to ultra-thin Internet cables with their computers at home and they became an experimental group. A control group was assigned to those who are similar level of school science achievement to the experiment group and did not use the web-based program. It was found that most of 9th grade students are able to use Internet at home, however, they do not prefer to use Internet for homework or task project. Rather, most of students used Internet for e-mail or information navigation. Students used internet to solve problems of science and perceived the benefits of Internet for science learning. However, there are not many students to utilize Internet for science homework or task project. Students expressed that they do not prefer to use a web-based learning program for science learning due to lack of interests in science. The effects on students who studied with this program appeared to be significantly high compared to those who did not study with this program. Students who studied with this program positively evaluated this program, in particular, they enjoyed animation effect and virtual experiments. It was concluded that a web-based program for science learning should be developed and distributed through Internet in an attractive and interesting format for students. It was also concluded that various web-based programs for science learning with animation effect and virtual experiments should be developed to increase students' interests in science as well as to improve students' science achievements.

The purposes of this study are to analyze sex education content in high school textbooks and to suggest new guidelines for high school sex education content from a gender equality standpoint. The study analyzes sex-related content from high school textbooks based on the 7th curriculum, including subject areas such as Technical/Home Economics, Sciences, Physical Education, Social Studies and Moral Studies. The analysis relies on the framework of Sexuality Information and Education Council of the United States that covers 4 levels and 6 categories as well as the framework of Choi (2005) that includes 36 themes in 6 different categories. The results of this study are as follows: First, high school sex-related textbooks are focused mainly on human development and human relations. Secondly, there is a lot of level 3 sex education content within the analyzed textbooks. Third, there are gender inequality issues in the coverage of such topics as pregnancy, contraception and sexual violence. Fourth, there are also gender inequality problems caused by content level. This study recommends that gender inequality issues be included in high school sex education guidelines in the future in order to provide improved and appropriate content for high school level sex education.

Purpose : This study was aimed to investigate the effect of knowledge and competence of first aid treatment among middle school students after the education on the injury treatment. Methods : The study design was randomized pretest and post-test control group nonsynchronized design. Study subjects were 32 3rd-grade students of Y middle school in P city and 34 3rd-grade students of M middle school in P city in this research. Among two 3rd-grade classes, one classes were randomly assigned to experimental group (32 students) and two were control group (34 students). The intervention for experimental group was providing five-time 45-minute injury treatment education. Results : 1. The First hypothesis : After intervention on the injury treatment education, knowledge of injury treatment in the experimental group was significantly higher than that of the control group(t=-6.480, p<.001). 2. The Second hypothesis : After intervention on the injury treatment education, competence of injury treatment in the experimental group was significantly higher than that of the control group(t=-15.121, p<.001). Conclusion : These findings suggest that the injury treatment education can facilitate knowledge of injury treatment, competence of injury treatment in the middle school student. Therefore, it is considered that the injury treatment education can be utilized as a effective way to implement the 7th nation curriculum.

The purpose of this study was to make valuable suggestions for improving environmental education(EE) teaching materials. For the purpose of this study, we analyzed four secondary school EE textbooks in the perspective of environmental literacy components. The findings of this study are as follows: (1) As a whole, the EE textbooks tend to focus the understanding environmental knowledge much more than environmental activities. (2) In 'main text' domain of EE textbooks, environmental information, including environmental issue knowledge, is much more focused than environmental attitudes and behavior, including socio-political and environmental issue knowledge. (3) In 'graphic data' domain, environmental information about environmental issue knowledge was most prevalent. (4) Most learning activities focus on 'issue skill' component, rather than 'attitude' and 'action' component. (5) The objectives of EE in the 7th national Curriculum were not explicitly embedded in textbooks and too much is inclined toward 'knowledge' and 'skill'. Accordingly, it is necessary to develop 'module-type' EE textbooks to enable integrative EE. Also, it is suggested to develop specific strategies for linking environmental knowledge and attitude/behavior.

The arithmetic operation have double-sided character. One is calculation as a process, the other is understanding in results as an outcome of the operation. We harbored suspicion on students' misunderstanding in an outcome of the operation, because the curriculum has focused on the calculation, as a process of arithmetic operation. This study starts with the presentation of this problem, we tried to find the recognition ability and character in the arithmetic operation. We researched the recognition ability for 7th grade 27 students who have enough experience in arithmetic operation when studying in elementary school. And we had an interview with 3students individually, that has an error in understanding in results of arithmetic operation but has no error in calculation. We focused on 3students' detailed appearance of the ability to understand in results of arithmetic operation and analysed the changing appearance after recommending unit record using operation expression. As a result, we could find the abily to underatanding in results of arithmetic operation and applicability to recommend unit record using operation expression. Through these results, we suggested educational implications in understanding in results of arithmetic operation.

This study has revisited the definition and characteristics of BIM to contribute to the better understanding of this concept. For the successful application of BIM in architectural design field, it should start with public buildings like schools which can be standardized. Since a number of conditions of school design appear to suit the schematic design phase for BIM application more than do other types of building design, the viability of BIM was examined by applying parametric modeling(one of BIM's basic characteristics) to mass study in schematic design phase for the configuration of schools that adopt the variation type of subject classroom design of the $7^{th}$ National Educational Curriculum. In addition, this modeling technique was used with software of Rhino 3D and Grasshopper, which will have a linkage to environmental analysis in near future. Finally, it can be expected that the work efficiency will be maximized if BIM is going to be applied in the early design stage instead of the end stage.
