수학의 기본 개념인 수직과 평행은 현행 2015 개정 교육과정에 따른 교과서에서 이전 2009 개정 교육과정에 따른 교과서에 비하여 축소되어 제시된다. 본 연구에서는 초등학교 수학에서 수직과 평행 개념의 지도 방안을 탐색하기 위하여 한국의 2009 개정 및 2015 개정 초등학교 수학과 교육과정 및 그에 따른 교과서에서 수직과 평행에 관한 내용을 분석하고, 한국과 싱가포르, 일본 교과서에서 수직과 평행 개념의 지도 방법을 비교 분석하였다. 교과서 분석을 바탕으로 4학년 2학기 4. 사각형 단원에서 다루어지는 수직과 평행 수업을 재구성하여 실행하였다. 교과서 분석 결과, 2009 개정 교육과정에 따른 교과서에서 2015 개정 교육과정에 따른 교과서로 변화할 때 단원명 및 차시 구성의 차이가 있었으며, 한국과 싱가포르, 일본 교과서는 수직과 평행의 개념 정의 및 활동 내용에서 차이를 드러냈다. 수업의 계획 및 실행에서는 수직과 평행 개념의 의미를 이해하고, 수선 및 평행선 긋는 방법을 탐색하며, 실생활과의 연관성에 초점을 두었다. 본 연구 결과를 통하여 초등학교 수학에서 수직과 평행을 의미 있게 지도할 수 있기를 기대한다.

본 연구는 새롭게 고안된 "지구중심운동 태양계 실험 모형"이라는 실험모형을 통해서 초등 예비교사와 초등학교 교사의 "천문개념 변화"에 초점을 맞추었다. 전주에 소재하고 있는 전주교육대학 졸업반 학생 31명과 전북에서 근무하는 초등교사 30명을 연구 대상으로 하였다. 먼저 학생들의 사전개념을 조사하고, 이 실험 모형을 활용한 수업전후에 개념검사를 실시하였다. 검사도구는 모두 10문항으로 내행성의 운동, 내행성의 위상과 크기, 외행성의 운동, 혜성의 운동으로 구성되었다. 분석 방법은 사전 검사에서 천문개념에 대한 유년적 개념을 확인하고, 사후 검사에서 초등 예비교사와 초등학교 교사의 개념이 어떻게 변화되었는지를 조사하였다. 결과적으로 지구 운동 중심 태양계 모형이 내행성의 운동과 내행성의 위상과 크기변화, 외행성의 운동에 관한 내용에서는 올바른 과학적 개념 형성에 효과가 있었다.

The main purpose of this study is to analyze the fourth and sixth grade in the elemental)' science contents using piagetian thinking patterns. An analysis of the elementary Science contents used the systems of Han Jong-Ha(1977), Lee Won-Shic and Lee Sang-On(1979). They analyzed the science contents based on Piagets' cognitive developmental stages. According to the results of this study, science contents consist of more difficult concepts those of children's thinking level. In other words, 6.4-19.3 percent to 23.5-25.0 percent in the fourth and sixth grade of the science contents are consisted with abstract level concepts that formal operational children can perform. But each grade, 99.2-95.3 percent of children have a difficulty in understanding such a abstract level concepts. They are in the concrete operation thinking level. Therefore, we say that children have difficulty in understanding of science contents and may lose interest in the contents.

본 연구의 목적은 2009 개정 수학 교육과정에 따른 교과서 작업에 즈음하여 중국 교과서와 우리나라 교과서를 비교 분석함으로써 현재 교과서의 개선점을 지적하고 새 교과서 작업에 시사점을 주고자 한다. 분석 대상은 중국 인민교육출판사의 초등수학 교과서와 2007 개정 교육과정에 따른 우리나라 교과서이다. 분석 영역은 수와 덧셈, 뺄셈으로 제한했다. 본 연구의 결과는 한국 교과서가 상대적으로 많은 언어적 표현의 사용, 할 일이 정해진 활동, 수학적 개념의 확장에서 유사한 절차 사용, 수와 연산 영역에서 더 큰 수의 사용, 다양하지 못한 수 감각 활동으로 나타났다. 이에 우리나라 교과서가 수학적 흥미와 도전감, 기초기본 개념 형성에서 상대적으로 취약하다는 것을 말해준다.

The purpose of the study is to find out students' misconceptions and the stability of misconceptions in the domain of mechanics. According to the incorrect choices by grades, three different kinds of conceptual change were identified ; (1) easily overcome misconceptions, (2) stable misconceptions, and (3) reinforced misconceptions. The analyses of the results showed that easily overcome misconceptions occurred in simple or visual concepts, stable misconceptions occurred in the concepts involving EGC(experiential gestalt of causation) or in the concepts overgeneralized in school teaming, and finally, reinforced misconceptions as grade level increases occurred in the concepts EGC with scientific logical procedures. The results on the type of conceptual changes may provide significant cognitive theoretic evidences on the sources of misconceptions.

The purposes of this study are how to consider the concept of magnetization by fifth elementary school students and how to change conceptions of students after the experiment with developed experiment sets. Personal interviews to the students were used for this study. to probe the conceptions of them, it allowed them to make gestures and to draw pictures through interview. From the analyses of the interview data, following results were found. Students have mostly understood the concept of magnetization, but have not remembered the term itself. And, the students believe that iron is magnetized only if iron was directly contacted a magnet. After the experiment, the students understand that iron could be also magnetized without direct contact to a magnet. And also, they could explain magnetization of iron powder around a magnet by applying the concept of magnetization. This new experiment is a good tool to understand concepts of magnetism.

Purpose: The purpose of this study was to explore the experience of the meaning in life for elementary school students. Methods: The conceptual framework was based on the five main concepts (meaning in life, creativity, experiences, attitudes, choice and responsibility) of logotherapy. Data from 1,600 higher grade elementary school students were analyzed for content of meaning in life. Results: The experiences of meaning in life were identified as follows: Important things in my life (people close to me, things that brings me happiness, to live in earnest, surrounding environment), Activities I like to do (relaxing, achievements, family relationships), Experiences that made me feel like I am loved (taken care of by family, material recompense, being respected), Times when I feel grateful (receive love and care, health), Importance of choices (consequences of bad choices, result of good life choices). Conclusion: These results suggest that elementary school students can understand meaning-centered health education and this kind of education is necessary to promote their wholistic health.

The purpose of this study was to investigate the effectiveness of teaching strategies for scientific conceptions in the units of oxygen and combustion in elementary school science textbook. 70 elementary school 6th grade students in Seoul participated. They were divided into experimental group and controlled group. Five scientific concepts were adopted from the units of oxygen and combustion in the 6th grade science textbook. Subjects' preconceptions were investigated by pre-questionnaires. A series of 6 instructional sessions based on the teaching strategy of cognitive confliction theory were given to the experimental group. By the end of the instructional session, a post-test was administered to both experimental and controlled groups. There was a statistically significant difference between post-test gains of the experimental and controlled groups. These results support the notion that the teaching strategy was effective for changing from preconceptions to scientific concerts.

This study aimed to understand students' learning in elementary science classes in terms of participatory perspective. Participatory perspective is based on the participationist views on learning. Based on the participatory perspective, this study used two concepts of participationism: 'the changes of learning on commognition' of Sfard (2007) and 'the identity' of Wenger (1998/2007). Based on these concepts, four episodes of an elementary science class were analyzed. The results showed that students carried out their learning from objective-level learning to meta-level learning. And students defined who they are by identifying and negotiating scientific meaning during the learning. These results showed students become members of science community through their participations in science class.

Over the years, the benefits of instructional manipulatives in mathematics education have been verified by classroom practice and educational research. The purpose of this paper is to introduce how the instructional material, specifically, geoboard could be used and integrated in elementary mathematics classroom in order to develop student's mathematical concepts and process in terms of the following areas: (1) Number '||'&'||' Operation : counting, fraction '||'&'||' additio $n_traction/multiplication (2) Geometry : geometric concepts (3) Geometry : symmetry '||'&'||' motion (4) Measurement : area '||'&'||' perimeter (5) Probability '||'&'||' Statistics : table '||'&'||' graph (6) Pattern : finding patterns Further, future study will continue to foster how manipulatives will enhance children's mathematics knowledge and influence on their mathematics performance.
