What kind of influence does cooperation learning have on scientific problem solving of an children?<BR> 1 - 1. Compare to large group education, and cooperation learning is how in discovery and statement of problem is there a difference?<BR> 1 - 2. Compare to large group education, and cooperation education is how in idea proposal and the application I against a problem solution is there a difference?<BR> 1 - 3. Compare cooperation learning to large group education is how in the conclusion against a problem solution is there a difference?<BR> Fifty five-year-old children, from h child care center located in sung dong-gu, seoul, participated in experiment. out of 40, 20 children were assigned to the large group education condition and 20 children to the cooperative learning condition.<BR> According to the pre-test, no meaningful differences between the results of two groups in terms of children"s scientific problem solving ability.<BR> The treatment session lasted for 5 weeks, and the children participated in science activities based on two different modes of learning : large group and cooperative.<BR> The post-test results wear analyzed using SPSS, and t-test for scientific problem solving between groups.<BR> Results of this study were as follow :<BR> The LT cooperation learning improved scientific problem solving ability, compared to those of children in the large group education condition.<BR> In conclusion, The learning together cooperation learning let scientific problem solving of an children be effective in an elevation.

본 연구는 급속도로 증가하고 있는 우리나라의 다문화 가정에서 발생되는 다양한 교육적 문제들(또래관계형성에 어려움을 나타내기도 하고, 사회적 놀이를 주도하지 못하거나, 유아교육기관에서 어떤 문제 상황에 부딪혔을 때 회피하거나 교사에게 기대려고 하는 의존적 경향)을 진단하고 그 해결방안을 모색하는 방안 중 하나로 피라미드 프로그램을 소개하는데 목적이 있다. 이 프로그램은 네델란드 암스텔담에서 Kuyk(2003)에 의해 개발된 것으로 2세 반에서 6세까지의 유아를 대상으로 친밀감, 확장하기, 아동주도, 교사주도의 개념을 피라미드처럼 촘촘히 구성한 교수·학습방법이다. 이 프로그램은 선행 연구에서 낙후된 환경과 이민자 가정 출신의 자녀들에게 적용하였을 때 언어 발달과 또래 관계 형성에도 효과적이라는 결과를 나타내었다. 이에 이 연구에서 다문화 가정의 자녀를 위한 교수·학습방법으로 Pyramid Method를 국내에 소개하여 다문화 가정의 유아들이 유아교육 현장에서 잘 적응하고 나아가 한국 사회의 구성원으로서 역할을 수행하는데 일조하고자 한다. 연구방법은 문헌연구 방법을 택하였다. This article explores Pyramid Method of early childhood education which is effective program to provide the sense of stability, language development and peer relationship. The basic concepts of Pyramid method are described such as nearness, distance, the child's initiative and the teacher's initiative. The basic concepts are inter-related and common in aspects of pedagogic and educational aspects. Pyramid Method adopts and develops from the positive results of Piaget and Vygotsky theories. Pyramid Method includes a new language approach in order to enhance children's ability of preschool or pre-kindergarten or kindergarten who are in low social-economic class and immigrant family. Pyramid Method includes three elements of intelligence which enhance development of young children such as cognitive, emotional, and physical intelligences. Levels of action of thinking are divided into creative level and meta-cognitive level. Play and initiative learning as child initiative are described as Pyramid method. Project and sequential programs as teacher initiative are described as Pyramid method. Program evaluations of Project Method are discussed such as internal evaluation which examine each child development individually and external evaluation which includes national experiment and Amsterdam experiment.
경제적 해체 가족과 일반가족의 가족 간 상호작용 유형에 따른 자녀양육스트레스및 아동의 또래 놀이 상호작용

본 연구는 경제적 해체 가족과 일반 가족의 가족 간 상호작용 유형에 따른 자녀양육스트레스의 차이와 아동의 또래놀이 상호작용의 차이를 밝혀보기 위하여, 해체 가족 196명과 일반 가족 300명 등 총 496명을 대상으로 연구를 수행하였다. 본 연구의 결과는 첫째, 가족유형과 가족 간 상호작용 유형에 따라 자녀양육스트레스에는 유의한 차이가 있었다. 둘째, 가족유형과 가족 간 상호작용 유형에 따라 아동의 또래놀이 상호작용에는 유의한 차이가 있었다. This research reveals differences in the stresses of child-rearing based on family interaction type between economically-dissolved and normal families. For this goal, research was carried out using 496 subjects, of whom 196 were from dissolved families and 300 from normal families. Research results were as follows. First, there were significant differences in child-rearing stresses depending on the interaction type of the family. Observed by family type, the child-rearing stresses of mothers in normal families were less than those of mothers in dissolved families. Observed by interaction family type, balanced families revealed the lowest child-rearing stress, the higher stress on mid-range and extreme families had the highest stress. Second, based on interaction type within the family types, interaction of children with their peers also showed significant differences. Observed by family type, peer interaction of children from normal families was higher than their counterparts in dissolved families. Observed by interaction family type, peer interaction was most positive in children from balanced families, while corresponding peer interaction was most negative in children from extreme families.

Fracture behaviors and strength of pipes with local wall thinning are very important for the integrity of energy plants. In pipes of energy plants, sometimes, the local wall thinning may result from severe erosion-corrosion damage. Recently, the effects of local wall thinning on strength and fracture behaviors of piping system have been well studied. In this paper, the monotonic bending tests were performed of full-scale carbon steel pipes with local wall thinning. Also, the elesto-plastic analysis is performed by FE code ANSIS. We compared the simulated results by finite element analysis with experimental ones. The failure mode, fracture strength and fracture behavior obtained from tests showed well agrees with analytic results.

The experimental and the analysis for effects of circumferentially local wall thinning on the fracture behavior of pipes were investigated. Local wall thinning for experimental was machined on the outside of pipes in order to simulate erosion corrosion metal loss. In addition, the pipes with local wall thinning on the inside were carried out FEM analyses, and it made a comparative study with that of outside. Fracture type could be classified into ovalization, local buckling, and crack initiation depending on the eroded length and eroded ratio. Three-dimensional elastic-plastic analyses were able to accurately simulate fracture behaviors of inside outside local wall thinning. Therefore, the fracture behaviors of the inside local wall thinning can be estimation with the outside local wall thinning.
