This study analyzed changes in sociality and democratic-citizenship among elementary school students in the information class and the science class at the Science Education Institute for the Gifted, who were divided into an experimental group and a control group. The experimental group engaged in the Learning Together (LT) cooperative form of learning for which the remix function of Scratch, an educational programming language, was applied, while the control group was given general instructor-led lessons. Members in the experimental group were able to modify processes during projects through the usage of the remix function, thereby actively participating in the projects and eventually generating team-based results. The post-class t-tests showed a greater degree of improvements in sociality and democratic citizenship for the experimental group that was offered the remix-function-based cooperative learning than the control group. Statistically significant differences were present between two groups particularly in "cooperative spirit" sub-domain of sociality and the "community" and "responsibility" sub-domains of democratic citizenship.

The intent of this study is to investigate the current situations and planning implications of elementary schools in urban housing blocks, and to propose the planning and design guidelines for them. The premise of this research is that an elementary school should function as a communal facility, shared by its community, so called open-school. 32 schools in three new towns were selected as sample cases and they were closely surveyed in terms of their site planning issues in residential blocks, and three sample open-elementary schools were analyzed in a comparative manner for finding their roles and functional fulfillment as a communal facility in the neighborhoods. Based on the findings, several planning principles and design techniques or devices are suggested for the utilization of elementary schools by local residents, mainly making issues of location, relationship to other facilities and open spaces in residential blocks, access, apartment layout, school building and outdoor spaces, and open program.

The main purpose of this paper is to develope elementary mathematics teaching-learning programs for pre-service elementary teachers. The elementary mathematics education program developed in this work is divided into two parts: One is the theory, the other is the practice. The theory deals with the foundations of mathematics, the objectives of mathematics education, the history of mathematics education in Korea, the psychology of mathematics learning, the theories of mathematics teaching and learning, and the methods of assessment. With respect to the practice, this study examines the background knowledge and activities of numbers and their operation, geometry, measurement, statistics and probability, pattern and function.

최근까지 개발된 디지털교과서는 전자칠판, 학습도구, 멀티미디어 등의 기능은 포함하였지만 자료검색 지원에는 취약점을 갖고 있었다. 본 연구에서는 검색기능을 지원하는 초등학교 디지털교과서를 개발하는데 목표를 두었다. 이를 위해 초등교사를 대상으로 검색기능 수요조사를 실시하였고 조사결과를 기반으로 디지털교과서를 설계하고 구현하였다. 개발된 디지털교과서는 XML로 기술되었고 의미 있는 단락 모음별로 검색할 수 있는 것이 특징이다. 디지털교과서의 사용후 설문에서 수업에의 유용성과 향후 사용의지에도 90% 이상의 교사가 긍정적으로 답하여 앞으로 초등학교에 보급될 디지털교과서에 검색기능이 반영되면 교수-학습에 많은 도움이 될 것으로 기대할 수 있다.

본 연구에서는 2015 개정 초등학교 수학과 교육과정의 성취기준 진술 방식이 학생들의 수학적 역량을 신장시키기에 충분한 정보를 포함하고 있는지 분석하였다. 분석의 객관성을 위하여 128개의 성취기준을 서영진(2013)의 내용 성취기준 진술 방식분류 기준을 이용한 틀을 바탕으로 내용 중심 진술, 활동 중심 진술, 수행 능력 중심 진술을 기준으로 분석하였다. 분석 결과 2015 개정 초등학교 수학과 교육과정 성취기준 진술 방식은 학생들의 수학적 역량을 신장시키기에 충분한 정보를 포함하고 있지 않음을 알 수 있었다. 이의 보완을 위해 성취기준에 '내용+기능'보다 더 다양한 요소를 담아야하며, 성취기준의 의미를 명확히 전달할 수 있는 다른 기준들도 개발해야 한다. 그리고 향후 초등학교 수학과 교육과정 성취기준 진술방식 개선을 위하여 성취기준에서 '기능'의 표현에 대한 보완이 필요함을 알 수 있었다.

In this paper we provide three results involving large Schr$\ddot{o}$der paths. First, we enumerate the number of large Schr$\ddot{o}$der paths by type. Second, we prove that these numbers are the coefficients of a certain symmetric function defined on the staircase skew shape when expanded in elementary symmetric functions. Finally we define a symmetric function on a Fuss path associated with its low valleys and prove that when expanded in elementary symmetric functions the indices are running over the types of all Schr$\ddot{o}$der paths. These results extend their counterparts of Kreweras and Armstrong-Eu on Dyck paths respectively.

The Purpose of this paper was to study the uses of the extra activity classroom of elementary school and the satisfaction of the students. The SPSS 10.0 for windows was used to analyze data collected from 397 elementary school students in Kunsan and Seocheon. The results were as follows: (1) More than 2/3 students have experienced special activities. The extra activity classroom was not effectively used showing less than one or two hours use a week for the lecture and extra activities. (2) Generally the students were satisfied at the condition of extra activity classroom, but dissatisfied with the degree of the independence, of deterioration, and of safety while moving. That is because the building and its equipment were old, and soundproofing and safety establishments were not well equipped. (3) There was difference between schools. Students at city had more satisfaction than at county. (4) The most important item of extra activity classroom was esthetics followed by function, safeness. and healthiness. It shows that the important item is being moved to esthetics and healthiness from function of extra activity classroom.

This study examined the knowledge structure constructed by children before formal instruction, and successive changes in the structural complexity of knowledge during the learning of the 'Structure and Function of Plants' unit. The researchers let the 5th graders draw the first draft of their concept maps in order to examine the pre-existing knowledge structure concerned with the unit and also four concept maps after completing every fourth lesson. Each concept map drawn by children on the basis of the previous one showed the degree of their current understanding on the structure and function of plants. The results revealed that only two levels of hierarchy and five relationships among the components of the first concept map(relationship, hierarchy, cross link and example) were proven to be valid in terms of conceptual relevance. According to the standard map, there was no change in hierarchy from the 2nd to the 3rd map, and in example from the 2nd to the 4th map. However, the gradual and successive increases of the scores in all components appeared in the children's maps throughout the unit. Knowledge restructuring occurred strongly in the early periods from the 1st to the 6th lesson, and the significant stable changes in tuning and accretion appeared throughout the whole lessons. The results also showed that there were no significant gender differences on the 5th grader's knowledge structuring.

표는 수학적 이해를 돕는 표현의 하나로 수학과 교육과정에서 지속적으로 제시되지만, 표에 초점을 맞추어 학생들의 함수적 사고를 이해하는데 표가 어떻게 사용될 수 있는지 알아본 연구가 드물다. 본 연구는 함수적 사고의 관점에서 초등학교 5학년 학생들의 함수표 이해가 어느 정도인지를 표 만들기, 관계 서술하기, 관계식 표현하기로 나누어 분석하였다. 연구 결과 약 75%의 학생들이 평균적으로 표 만들기를 할 수 있었는데 이 때 제시된 정보만을 이용하여 가로형의 표를 창안하는 학생들의 비율이 가장 높았다. 또한 서술형에 비하여 기하패턴 문항을 해결하는데 학생들이 어려움을 드러냈다. 본 연구를 통하여 학생들이 '함수표'로서 표를 사용할 수 있는 지도 방향에 대한 시사점을 얻을 수 있을 것이라 기대한다.

This study is done to classify the upper body shapes for late elementary schoolgirls. The sampling was done for 11~12 years-old-girls resident in Busan and Kyungnam. Based on the somatometric charateristics of them, 33 anthropometic and 7 photogrphic measurment data were acquired from every girl. These data are statistically analyzed with the following methods; Factor Analysis, Cluster Analysis, and Discriminant Analysis. Resulting from the factor analysis, it is shown that 79.95% of the whole variances can be explained with 8 factors. Through the cluster analysis, 3 types of upper body shapes can be categorized as follows: Type I has average horizontal size, big vertical size and lots of protruded chest ; Type III has big horizontal size, the mean vertical size, and big upper angle of the back ; Type II has small horizontal and vertical size and long surface length of the upper body. Through the discriminant analysis, the high discriminative items in discriminant function are follows: Upper chest circumference, arm length and waist front length of discriminant function I and waist depth, front length, back breadth, nipple to nipple breadth and upper chest circumference of discriminant function II have large coefficient values.
