The purpose of this study was to develop science research ethics guidelines for elementary school teachers. To develop the guidelines, authors have conducted the following procedures: Development of guidelines through literature reviews; and an application of the developed guidelines to classroom sites. Authors established sections and formats of guidelines for science research ethics through literature reviews and developed contents of major sections and subsections and their explanations and descriptions. After that, authors applied the developed guidelines at elementary science classes and collected data through semi-structured interviews with science class teachers and checklists to reflect on and complement the contents of the guidelines. To secure the validity of guidelines, authors requested a validity assessment to four science education experts and one ethics education specialist. As a result, the CVI for the guidelines was found to be 0.9. Finally, authors developed the final guidelines by adding "Case Examples of Application" by adopting requests of elementary school teachers who used the provisional guidelines.

This study asked preservice elementary teachers to conduct an inquiry of observing the moon, and analyzed the phenomena observed, difficulties experienced, and pedagogical suggestions by the preservice teachers. Participants were 31 undergraduate students enrolled in a science course in a university of education. As a part of the course, the preservice teachers observed the moon for about a month and completed personal journals which described the phenomena they observed, difficulties they experienced, and the pedagogical suggestions to help elementary students conduct the same inquiry activity. The analysis of the journals revealed that the preservice teachers observed the moon mostly during the evening or night and that they noticed lunar phases, directions, altitudes, and color and brightness more frequently than other phenomena. The preservice teachers experienced difficulties related to the observation time, lunar phases, directions, and altitudes, and, reflecting on their own experiences, suggested a variety of pedagogical ideas about these difficulties. The pedagogical suggestions by the preservice teachers also included how to help elementary students keep their interest and perform the moon observation for a rather long period of time. Implications for moon investigations in the elementary school science classroom and relevant research were discussed.

The purpose of this study was to analyze elementary school teachers' implementation for the emphasis on the revision, major contents, teaching and learning method, and evaluation in the 2009 revised national science curriculum. To fulfill the purpose of this study we carried out a survey with 222 elementary school teachers. Main findings of this research were as follows: First, they highly agreed to the increase in class hours and the application of subject classroom, but they had a lower recognition for setting the subject groups. Second, the degree of necessity in discussion and STS was relatively high, but the degree of implementation in science writing, discussion and STEAM was low. Third, in teaching and learning method, they showed a high performance for mutual cooperation, student-led activities and communication, but, a low implementation for open inquiry and instruction considering individual differences. Fourth, in the evaluation of science learning, they showed a high implementation for evaluation based on achievement standards and one based on the understanding and application of basic concepts, but, a low implementation for the development of common evaluation tools. Fifth, it seemed that their recognition for amount, level and interest of science contents and inquiry activities was appropriate and positive.

In this study, we analyzed the problems of grade 3~4 science textbooks developed for the 2007 revised national curriculum raised by elementary school teachers. 53 elementary school teachers were selected and asked to complete the open questionnaire to find out the problems they experienced or perceived when they taught the corresponding unit of the science textbooks. The responses were coded and categorized through researchers' cross analysis. The result revealed various problems in using the science textbooks in real classroom context. The problems were divided into three dimensions as inquiry activity aspect, science knowledge aspect, and science learning assessment aspect. Each dimension consisted of several categories. We explained the frequency and representative examples of the problems in each category. These can provide some guidelines and implications for new science textbook developers and science education policy makers.

The purpose of this study is to examine the educational effects of STEAM class by focusing on $21^{st}$ century learner competencies based on burning and extinguishing unit. Two 6th grade classes were divided into experimental group and comparison group to treat the experimental group with elementary science class using STEAM class. General class according to teacher manual was implemented for the comparison group. Elementary science class applying STEAM class was conducted for 9 lessons throughout the experimental period. The result of this study are as follows. Elementary science class with STEAM class had significant effect on 21st century learner competencies compared to traditional instructor-led classroom. Looking specifically, it was a significant difference in the three domains of the seven domains (problem solving, collaboration, flexibility). The study results indicated that STEAM class was effective in improving learners'recognition of 21st century learner competencies.

The purpose of this study was to investigate the perceptions, intake levels and information needs of elementary school students on artificial food colorants in order to provide better understanding and proper dietary education to these students. From May to June 2010, a survey was conducted from 315 elementary school students at fifth and sixth grade level who were living in Seoul. The questionnaire was distributed by 14 elementary school teachers to their classroom students. The results showed that food safety was regarded as the most important factor in purchasing food items, and artificial food colorants were the most interested among various food additives. Although there was a lack of general knowledge and the students' estimated intake levels of artificial food colorants from processed foods were comparatively low, most (82.7%) believed that artificial food colorants were dangerous for health. The information they wanted to know most was the safety, necessity, and function of artificial food colorants, in order. Above results suggested the necessity of providing accurate information on artificial food colorants to elementary school students possibly by developing educational materials which can improve the perceptions on artificial food colorants and encourage a safe dietary life.

수준별 학습지는 열린 교실에서 주요한 학습 자료이다. 그러나, 초등 학교에서 학습지들이 종종 원칙없이 개발되어 왔다. 특히, 과학 교육적 요소들이 학습지 개발에서 무시되어 온 경향이 있다. 이러한 문제점들을 개선하고자 과학 지식의 맥락적 특성과 교육적 구성주의를 고려한 수준별 학습지 모형을 개발하였다. 이 모형의 틀은 탐구와 학습 과제에 나타나는 맥락으로 구성되어 있다. 학습지의 수준은 탐구요소의 통합성과 맥락의 친근성을 바탕으로 결정하였다.

이 연구는 초등학생의 과학 수업 대화 및 글쓰기에 구현된 언어 표현의 국어 문법적 특성에 근거하여 그들의 과학적 의사소통 능력의 양상을 조사하였다. Brown et al. (2010)의 증거에 기반한 추론 프레임웍을 순환학습모형에 접목하여 작성한 수업안을 초등학교 5학년을 대상으로 "날씨와 우리 생활" 단원에 적용하였다. 수업 대화에 활발히 참여한 학생 8명의 대화 전사본과 그 학생들의 과학 글쓰기 문장을 연구 자료로 활용하였으며, 텍스트의 내용 및 논리 관계 분석 방법을 적용하여 문법적 특성을 조사하였다. 연구에 참여한 초등학생들은 데이터 분석, 증거 해석, 규칙 적용, 설명 구성 등의 맥락에서 사용되는 과학 언어의 문법적 구조와 일치하지 않는 언어 사용의 양상을 보였다. 그러나 부분적으로 명사화 방식의 문법적 은유를 사용하거나, 적절한 인과 관계의 문법 구조를 사용한 글쓰기 사례도 제시되었다. 교사의 교수법적 안내 발화나 교과서 텍스트의 문법 구조를 통해 학생들이 과학의 문화에서 사용되는 언어 활동의 양태를 경험하면 초등학생도 유사한 과학적 말하기와 글쓰기를 나타낼 수 있었다. 학생들이 증거에 기반한 추론에 근거한 과학지식 구성의 맥락에 적절한 언어 사용 이해와 이에 대한 문식 기능을 습득할 수 있게 하려면, 과학 학습에 관한 언어 사용 모델을 접할 기회를 충분히 제공해 주는 것이 필요함을 논의하였다.

This study explored practicing elementary school teacher's beliefs of scientific inquiry and scientific inquiry teaching methods. Defining teacher's beliefs as a broad construct, we tried to examine the teachers' understandings about the scientific inquiry and scientific inquiry teaching method. This study drew on interview data from 10 elementary teachers in busan and changwon area of korea. Conclusions of this study include; First, we found that elementary teacher's beliefs of inquiry were represented variously. And they considered that inquiry is the important goal of science education. They though that the goal of science education is development of Scientific inquiry skills, Scientific thinking skills, development of Creativity and problem solving ability, increasing interest about science, understanding of the basic concepts of science and apply of real-life. second, most of the teachers though that Scientific inquiry is scientists activities, they defined 'the process of creation of new knowledge', 'the process of deriving theory', 'solving process of intellectual curiosity', 'Problem-solving process'. third, they considered that teaching method of scientific inquiry is open inquiry activities. however, they thought that there are many difficulties to actually apply. Understanding teachers' beliefs has implications for both the enactment of inquiry teaching in the classroom as well as the uptake of new teaching behaviors during professional development, with enhanced outcomes for engaging students in Science.
