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 was initiated by the idea to help students to be more ideally educated following the 7th curriculum that seeks the proactive students along with creativity for the 21st century. Mind-map was the main tool throughout the study and this was performed to find answers for the following questions : 1) to examine how students' drawing a mind-map affects their mathematical tendency or emotional aspects (motivation for study, interest, etc); 2) to investigate the types and characteristics of mind-maps that students draw; 3) to analyze advantages and obstacles that they experience during the process of drawing a mind-map and provide some suggestions for overcoming them. The research shows that students were highly motivated by the drawing a mind-map. There are types of mind-maps: tree shape and radial shape, and each shape has its own advantages. But the more important factor for being a good mind-map is where and how each concept is located and connected. Although it is true that drawing a mind-map helped students to see the bigger structure of what they learned, but there are several hardships taken care of. The study suggests to extend the experiment to various levels of students and diverse contents.

It is time to put our top priority on the computer education to cope with rapid chage in technology and expansion of information. With 6th educational reform plan, from 1995 computer courses will be offered as elective subjects in the most of middle schools. However, detail planning for training of computer courses will be offered as elective subjects in the most of middle schools. However, detail planning for training of computer teachers and providing facilicles for computer education hasn't been adequately prepared yet, This will bring about confusion in computer education. The purpose of this study is to propose how to renovate the ordinary classroom into computer classroom. Followings are the suggestions for the educational specification for the renovated computer classroom for middle school in the urban area. 1) Purpose of computer classroom, 2) Size of computer classroom, 3) Curriculum design and class hour, 4) Facilities, 5) Environments, 6) Equipment and media(lighting and electric system, acoustical treatment, cooling/heating and ventilation system), 7) Activity area(Teacher workstation, Student workstation, Support area, Display surface). For the promotion of computer education, the legal, financial and administrative supports by concerned authorities should be established ahead of discussing the contents of computer education.

To get an appropriate and meaningful performance assessment outcomes and to provide the base of essential elementary educational evaluations, we had tried to establish achievement standards, assessment standards and had developed appropriate assessment tools in 「Intelligent Life」 course of the elementary school in this study. The following things were taken into account to establish achievement standards, assessment standards and to develop assessment tools. First, managing deeply not only cognitive domain but also the basic inquiry skills and affective domain, all-round educational properties of integrated courses were likely to come out. Second, evaluating instructional processes as well as instructional results, we had developed assessment standards in elementary 2nd grade's 「Intelligent Life」 course. Third, developing assessment standards on the basis of the 7th Curriculum, we had examined both text book and teacher's guide to promote effectiveness of field application. The type of an assessment tools had been developed variously, considering the characteristics of the elementary lower grades and properties of elementary 2nd grade's 「Intelligent Life」 course. We had developed assessment tools to observe and evaluate practical achievement levels, placing great importance on the types of an assessment tools including observing, narrative of inquiry, report, etc. As a result of investigation of elementary teachers' understandings of the developed achievement standards, assessment standards, and an assessment tools, were revealed in the affirmative on the whole.

This study investigates interior and exterior environments and arrangement forms of school buildings from elementary to high school which were recently built in Daegu since the 7th Educational Curriculum. In addition, this study analyses how outside noise affects inside environment of schools. This study found that the noise level criteria of school facilities(such as exterior learning sites and outer walls of school buildings) adjacent to street of one side satisfiedly corresponded to the level and criteria, 65dB(A), of school health law. However, the noise level and vibration criteria of school facilities adjacent to street of two sides did not satisfiedly corresponded to the level or criteria, 65dB(A). In case of classrooms, the inner noise of educational facilities with windows closed and also close to both the street of one side and of two sides satisfiedly corresponded to the level or criteria. 55dB(A), of school health law. In spring and tall, the windows are more open them usual for ventilation, and leaving windows open can lead to noise from outside. Thus, it is urgent to prepare for this situation.

The purpose of this study was to evaluate the effects of BLS education program in middle school students and their retention period. The participants were 70 middle school students in D와 Y middle school in D city. Data were collected from 16th July to 26th November in 2012. Students were tested for their knowledge, attitude before, immediately after, 8 weeks after, 16 weeks after BLS eduction. Data were analyzed frequency, percentage, $x^2$-test, t-test and repeated measured ANOVA using SPSS/PC 21.0 statistical program. Knowledge, attitude, performance ability were significantly increased experimental group compared to control group. Knowledge and attitude 8 weeks after, and performance ability were significantly decreased compared to 8 weeks after. And Knowledge, attitude, and performance ability were significant decreased among groups. Therefore, to maintain the knowledge attitude and skills of BLS, appropriate renewal time are necessary in regular school health curriculum.

In this study, we applied the elementary performance assessment instrument on 575 theme in science instruction which it had been developed on the previous study. Sixty-seven elementary students participated in this study and were assigned into two groups: One was assigned to an experimental group since they were taught with the instrument (N=32) and the other was assigned to the comparison group since they followed teachers guide of 7th Korean National Curriculum (N=35). Prior to and after teaching, tests on the science attitude, science process skill, and science knowledge domains were administrated. The results were analyzed quantitatively. Further, we also investigated students recognition about the instrument and the science class qualitatively according to the instrument. The results showed that there were statistically significant improvements on science process skills and aspects of the understanding of science knowledge. Many students were aware of them positively as well. However, a few problems, including too many amounts of writing and difficulties in communication with one another, were appeared.

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.
