The number of elementary school classroom's students. It will be decreased to 21.1 OECD even and furthemore to 19.8 in 2030. Therfore fore the time being the number of elementary school classroom's students will be sustained in 20~22. But nowadays the classroom's area which is fitted the number of 30 is too big compare with the number of 20~22. This reserch is finding the profit module of elementary school's classroom of the number of 20~20. Using one student's unit and various displays of class by teaching methods, I found the conclusions as follows. 1st, the horizontal length of center line is 7,100~7,500 and the vertical length of center line is 7,000~8,000 in the classroom's area of a team of 2. 2nd, if you make adjustment those lenghts to 30cm module, horizontal length is transfered to 7.2m, 7.5m, and vertical length is transferred to 7.2m, 7.5m, 7.8m. Therefore unit classroom's module are $7.2m{\times}7.2m$, $7.5m{\times}7.5m$ in square, and $7.2m{\times}7.5m$, $7.2m{\times}7.8m$, $7.5m{\times}7.8m$ in rectangular. 3rd, the areas of modules are $7.2m{\times}7.2m(51.84m^2)$, $7.5m{\times}7.5m(56.25m^2)$, $7.2m{\times}7.5m(54m^2)$, $7.2m{\times}7.8m(56.16m^2)$, $7.5m{\times}7.8m(58.5m^2)$. Therfore th area of module is from $51.84m^2$ to $58.5m^2$ compared to nowadays' classrooms.

“초등학교 수학의 주된 목표는 수 감각 개발이 되어야 한다” 는 Everybody Counts (1989)의 진술에서 알 수 있듯 수 감각은 최근 그 중요성이 강조되고 있으며, 수학교육의 목표와 내용을 대표하는 용어가 되고 있다. 이는 지금까지 교실에서 이루어진 연산 중심수업에 대한 반성이고, 의미 부여 학습을 강조하는 현재 진행중인 교육과정 개혁 움직임에서 쉽게 찾아 볼 수 있다. 그러나 아직 수 감각이라는 용어에 대한 명확한 정의가 내려져 있지 않을뿐더러 그 하위 구성요소를 분류하는데도 문헌마다 서로 일치하지 않는다. 따라서 본 연구에서는 문헌에 나타난 수 감각의 정의와 그 하위 구성요소들을 고찰해 보고, 아동들에게 수 감각을 길러주기 위한 수학 학습에 대해 알아본다.

현대 사회의 교육은 기존의 오프라인만의 교육에서 벗어나 점진적으로 e-런닝, 원격교육, 사이버교육으로 진화하고 있다. 교수-학습은 단지 교실에서만 가능하다는 기존의 관념에서 벗어나, 다양한 매체와 방법을 동하여 교수-학습이 이루어지고 있으며, 앞으로도 다양한 변화가 있을 것이다. 사람, 컴퓨터, 그리고 사물이 장소와 시간에 구애받지 않고 언제, 어디서나 하나로 연결되는 사회, 즉 인간의 생활공간 전체가 거대한 네트워크로 연결되는 유비쿼터스 사회는 우리 교육에도 많은 변화를 주리라 예상되며, 초등학교 교육 현장에서도 RFID는 다양한 방법으로 전개되어 나갈 것이다.

"교사였을 때 경험으로 비춰보면 한 교실에 학생이 40명 있을 때와 20명이 있을 때 눈에 들어오는 애들이 달라요. 소도 마찬가지에요. 무조건 마릿수가 많다고 경쟁력이 높은 건 아니 라는 거죠." 경북 김천시 개령면에 있는 서부목장은 요새 활기가 넘친다. 수학교사였던 둘째 아들 강동구 씨가 후계자로 내려와 최신기술을 접목하면서, 산유량은 물론 수익까지 늘었기 때문이다. 출타한 부모님을 머신해 초등학교 5학년 때부터 혼자 직접 착유를 해놓기도 한 기특한 아들이었다는 강동구 씨와 강희수 이찬숙 대표를 만나봤다.

본 연구에서는 LOGO를 개발한 Papert의 철학에 따라 아동이 자유롭게 학습할 수 있는 Microworld를 통해 수학을 새로운 관점에서 접근하고, 아동에 맞게 수학을 재구성하여 제공한다는 적극적인 교육적 배려에서 정규교육과정(교실), 특기적성, 자기 주도 학습 등 다양한 학습 환경에 가능한 컴퓨터 창의력수학 프로그램을 개발하고자 한다. 많은 관심에 비해 창의력 교육이 구체적으로 학습과 관련되어 있지 않고, 체계적인 교육과정을 따라 이루어지지 않고 있으며, 컴퓨터 교육 역시 한글 워드나 Excel과 같은 기능 위주의 학습으로 컴퓨터 학습에서 기대하는 알고리즘 학습은 소홀히 다루는 문제점이 있다. 이러한 창의력 교육과 컴퓨터 교육에 대한 문제점에 주목하여 학교 교과과정과 연계된 컴퓨터 알고리즘 학습과 수학 학습이 함께 가능한 컴퓨터를 통한 수학적 창의력 향상 프로그램을 개발하고자 한다. 이에 학교 교과과정에 연계하여 컴퓨터 알고리즘 학습과 수학적 창의력 향상에 적합한 매체로 LOGO 마이크로월드를 택하고, 이를 이용한 컴퓨터 창의력 수학 프로그램이 가지는 특징을 살펴본다. 이렇게 개발된 프로그램은 검증을 위해 봄학기 초등학교에서 실험연구가 계획되어 있다.

The purpose of this study was to investigate students' and parents' perceptions of nutrition education. In this survey, 7,577 elementary school students and 6,003 of their parents across the country were surveyed about the necessity of implementing nutrition education, its present status and problems and future methods for nutrition education implementation. The results showed that 96.6% of the parents and 62.8% of the students responded that nutrition education was urgently needed, at least once per week in the lower grades of elementary school, and that it should be related to and coordinated with special activities class. In addition, the survey showed that students and their parents wanted nutrition teachers to establish a nutrition counseling room, a practical cooking class, a special activity class, and/or dietary camp during school breaks. With regard to the status of nutrition education at home, there was statistical evidence that suggests significant differences between urban and rural schools. Approximately 63% of the parents indicated that they had difficulty teaching nutrition education in their own homes, because it was difficult to determine the dietary habits and nutritional status of their children. When asked about attending a dietary class for parents, 74% expressed their intent to attend. Parents were most interested in learning about cooking practices, diet therapy, and food information in that order. The results showed that the most effective method of dietary education was to teach appropriate nutritional practices in school and at home simultaneously. Hence, necessary information and education should be provided through special lectures, special cooking classes, and dietary classes for parents. The conclusions of this study suggest that a variety of education programs should be developed to achieve effective nutrition education for students and their parents.

The flipped learning is an inverted teaching model where students learn the basic concepts using short videos at home and then come to class to enable effective practice and interactions among teachers and students. However, due to the students' lack of self-regulated competence, most students have difficulties of comprehending the instructional materials out of class by themselves. In this paper, we develop an interactive app for active flipped learning in the mathematics courses in the elementary schools. We examine the effectiveness of the active flipped learning on learners groups with different achievement levels in learning 4th grade mathematics concepts in the elementary schools. The pretest and posttest survey results show that the proposed flipped learning approach has better performance compared to the traditional flipped learning approach.

From one elementary school of last 2005 Pusan was started "the school police" system is being applied the effect in the elementary school of the human nature receiving entire country. But "with school police system " have a limit about manpower that is insufficient. So we try to make "Baumter-Gikimy " that is extended scollo police in seoul. Despite being like that at 2010 and 2011 cannot forget the elementary student suicide events which are shocking or sexual assault events occur from the campus.From elementary school 4 grade the students between junior high school 1 grade crime occurrence ratio are highest. These people the group leaving out mainly, suicide, with group violence and sexual assault problem gets up same problems. In order to solve like this problems stands the countermeasure of the dimension which is national certainly is necessary. But so far only the damage student and the parents have an interest in about like this problems and they hurt. We the smart phone of Android bases it will be able to solve like this problem points [ayp] from under planning and development boil the elementary student safe helper it will can use. When it uses the elementary student safe helper system which we propose before the accident occurs, it will grasp the state information of the student and it will be able to prevent an accident in advance. We will try to more efficient safe guard to elementary school student by real-time monitoring skill soon.

Daejeon school-based toothbrushing program using toothbrushing room started at 2007. Ministry of Health and Welfare started national toothbrushing room program without pilot project at 2011. The aim of this study was to provide the basic data to assess of the effect of this program. 59 experimental subjects and 60 control subject were selected after written consent. Oral Examination was done by 1 dentist using WHO standard and Survey of Child Oral Health-Related Quality of Life(COHIP), oral health knowledge and oral health behavior were done using self-registration form. We analyzed the result after adjusting economic status and subjective for the difference between experimental and control groups using SPSS 19.0. The experimental group had lower plaque index, better COHIP and more oral health knowledge significantly(p<0.05). But, The significance was not found in dental caries index and oral health behavior. We suggested the oral health education program and other dental caries prevention program including sealants were needed to prevent dental caries, although school-based toothbrushing program could improve COHIP.
