The purpose of this study is to analyze classroom norms formed in inquiry activities of elementary science classes and to consider about the actual problems in enacting school science inquiry. Focusing on the inquiry activity cases of two classes, the data were collected through classroom observation, student interview, teacher interview and questionnaires. Firstly, classroom norms were categorized into three categories theoretically: norms for behavior guidance; general academic norms; and scientific inquiry academic norms. The subcategory norms of each category were extracted inductively and the features, the causes of formation, and the influences on inquiry of each norm were also analyzed. Based on the analyses on classroom norms, the researchers identified three actual problems in enacting school science inquiry. First, the collective traits of school science inquiry caused structural problems in science classrooms. Second, teachers used their authorities in different ways according to phases of instructions. Third, the conflict cases were reported between general values for education and specific values for science inquiry. Educational implications are discussed in terms of the practices of school science inquiry and of the understanding classroom phenomena.

This study was conducted to obtain a basic information related to a more systematic safety education and measures against children's accidents by a descriptive survey with regard to accidents actually experienced by elementary schoolers, their perceived safety education activities and school facilities to their safety lives. The data was collected among 1,654 pupils, belonging to the 5th and 6th grades in Pusan from Nov. 20 to Dec. 1, 2000. The data was analyzed using SPSSWIN(7.5). The results were as follows ; 1. According to the perception by elementary schoolers, they received safety life instruction at school in most cases from teachers in charge of their own class (41.0％). Such safety education was provided often during formal classes(24.4％). Traffic guidance was given by parents, highest in frequency(67.3％). 2. Matters as most often treated during safety life instruction were safety knowledge or dangerous things(37.5％). A majority of notices of school safety instruction were presented sometimes(48.4％). Source of knowledge about safety lives included teacher (35.3％), parents(32.9％), TV and newspaper (29.9％). As a source of knowledge of emergency treatment, school nurses were accounted for 41.3％ that was highest. 3.Among the 1,654 students, 91.8％ experienced at least more than one case of safety accident. The most frequent type and cause of safety accident were wound(33.7％). and self-carelessness(38.4％) respectively. In most cases, the subject experienced such accident during a break time(32.2％) and at a playgrounds. Part of body as most often damaged by accidents were arms and legs, 25.4％ higher than any other sides problem solving measures against the accident were taken by school nurse in most cases, 44.8％ in percentage point. 4. Those students' perceived safety management of school facilities showed that they considered classroom facilities as most safe (61.6％), while playground facilities as least safe(42.8％). They also responded that the treatment of glass fragments or stones at playground is the most important item of safety management.

The purpose of this study was to examine the effects of storytelling skill on science learning motivation and space perception ability. For this study the 5 grade, 2 class was divided into a research group and a comparative group. The class was pre-tested in order to ensure the same standard. The research group had the science class with storytelling skill, and the comparative group had the class with teacher centered lectures for 10 classes in 10 weeks. The storytelling skill was focused on finding stories, constellation searching, story deciding, story hero deciding, story composition, storytelling completion. To prove the effects of this study, science learning motivation was split up according to attention power, relation, confidence, and sense of satisfaction. Also, space perception ability consisted of two-dimensional rotation, 3 dimension rotations, reflection, three-dimensional searching, number of block, and figure type in pattern. The results of this study are as follows. First, using storytelling skill was effective in science learning motivation. Second, using storytelling skill was effective in space perception ability. Also, after using storytelling skill was good reaction by students. As a result, the elementary science class with storytelling skill had the effects of developing science learning motivation and space perception ability. it means the science class with storytelling skill has potential possibilities and value to develop science learning motivation and space perception ability.

Science drama can be an useful tool for understanding the nature of science, Science-Technology-Society relationship by providing indirect experiences to young students. Specific science concept and knowledge can also be learned with high interests. In this study, to explore the usefulness of science drama in elementary science lessons, two scripts of science drama and lesson plans were developed and implemented. Six step model for science drama lessons was also suggested. One was 'Manhattan Project' which dealt with social, ethical responsibility in using science & technology (science argument drama), and the other was 'Mom, My blood type is O' which explained the heredity of blood type (science concept drama). Two teachers were asked to write their journals during preparation and implementation of science drama lessons, and the lessons were observed by the researcher and video taped for analysis. Some students were interviewed just after the lessons by the teacher and all students were asked to write their impressions, change of their thought, what is leant etc. Overall responses of students and teachers on the two science drama lessons were very positive, 'Mom, My blood type is O' got more positive responses, and girls were more positive than boys. Some students anticipated another science drama even suggest topics for it. 'Mom, My blood type is O' was successful in making students (grade 3) understand the knowledge related with heredity of blood type (71% of the students got perfect answer). In 'Manhattan Project' students (grade 5) perceived more diverse location of responsibility after the lesson, but the danger and harmfulness of atomic power was embossed. This implied the need of more careful planning for the relevant learning activities before and after the play of science drama.Two teachers perceived the science drama as a new, useful tool for some subject which is hard to deal with by other teaching method. They were also satisfied with students' high interest and engagement during the science drama lessons but the extra time and effort for the lessons were pointed out as a main difficulties.

The purpose of this study was to explore the nine components of computational thinking (CT) practices and their operational definitions from the view of science education and to develop a CT practice framework that is going to be used as a planning and assessing tool for CT practice, as it is required for students to equip with in order to become creative problem solvers in $21^{st}$ century. We employed this framework into the earlier developed STEAM programs to see how it was valid and reliable. We first reviewed theoretical articles about CT from computer science and technology education field. We then proposed 9 components of CT as defined in technology education but modified operational definitions in each component from the perspective of science education. This preliminary CTPF (computational thinking practice framework) from the viewpoint of science education consisting of 9 components including data collection, data analysis, data representation, decomposing, abstraction, algorithm and procedures, automation, simulation, and parallelization. We discussed each component with operational definition to check if those components were useful in and applicable for science programs. We employed this CTPF into two different topics of STEAM programs to see if those components were observable with operational definitions. The profile of CT components within the selected STEAM programs for this study showed one sequential spectrum covering from data collection to simulation as the grade level went higher. The first three data related CT components were dominating at elementary level, all components of CT except parallelization were found at middle school level, and finally more frequencies in every component of CT except parallelization were also found at high school level than middle school level. On the basis of the result of CT usage in STEAM programs, we included 'generalization' in CTPF of science education instead of 'parallelization' which was not found. The implication about teacher education was made based on the CTPF in terms of science education.

The purpose of this study was to investigate the performance of elementary school dietitians in terms of nutrition education in the northern portion of Gyeonggi province. Self-administered questionnaires were given to 50 dietitians who have worked in elementary schools with self-operation food service, and 35(70%) dietitians returned the questionnaires. The results are summarized as follows: no students took part in nutrition education as a regular course, but all dietitians performed nutrition education in passive ways, such as 'using home correspondence'(39.0%), 'bulletin board/poster'(22.0%), 'using the internet'(13.4%) and 'indirectly through a classroom teacher'(12.2%). Most respondents performed nutrition education 'one time/month'(66.0%) or 'one time/week'(20.0%). The respondents thought that suitable teaching times for nutrition education were 'during a related subject'(35.5%), 'during lunch time'(22.6%) rather than 'during an independent subject'(16.1%). Most of the dietitians(94.3%) did not perform nutrition counseling because of 'a lack of opportunity'(72.7%) and 'workload'(27.3%). Additionally 88.6% of respondents did not have the time of for nutrition counseling for parents because 'am not a teacher'(56.7%) and 'workload'(30,0%). Information sources for nutrition education were mainly 'internet'(71.4%) and 're-educationa1 materials'(17.1%). They possessed instructional materials in the forms of 'printed materials'(35.1 %), 'exhibition/bulletin board'(31.2%), and 'electrical materials'(33.8%), 'but did not have 'solid materials' such as food models and dolls. Generally they had mostly 'leaflets'(82.9%), 'bulletins'(68.6%), 'internet'(57.1%), and 'CDs'(57.1%). Preferences for instructional materials used were 'printed materials'(46.2%), 'exhibition/bulletin board'(36.5%), and 'electrical materials'(17.3%) 'Leaflets'(80.0%) were mainly used; 'CD'(17.1 %) use was low compared to the proportion possessing CDs. The topics frequently chosen by the subjects for nutrition education were 'table manners'(82.9%), 'basic concepts of food and nutrition'(80.0%), and 'proper food habits'(80.0%), but the topics helpful for practical use, such as 'how much do I eat'(20.0%) and 'nutrition labeling'(37.1%), were not included frequently. The respondents thought that 'eating only what they like'(60.0 %), 'intake of processed foods'(17.8%), and 'obesity'(17.8%) were the most common nutritional problems among elementary school children. They also thought that establishing a regular course for nutrition education was an effective way to cut down on these nutritional problems. In conclusion, nutrition education programs that are combined with effective instructional materials and practical topics should be developed. Additionally, it is recommended that dietitians act as teachers who participate in regular courses as soon as possible.

The purpose of this study is to examine what epistemological beliefs pre-service teachers have about science depending on the situation, and to explore in-depth changes in epistemological beliefs through disciplinary reading. For this purpose, 77 essays written by pre-service elementary school teachers after reading Feynman's 'the meaning of it all' were analyzed using an inductive analysis method. As a result of the study, the epistemological beliefs of pre-service teachers were divided into two situations: 'science in subject learning' and 'science in daily life', and the epistemological beliefs formed in the 'science handled by scientists' situation were analyzed after reading the book. Each situation was divided into sub-categories of 'Impression of Knowledge', 'Source of Knowledge', 'Justification of Knowledge', 'Variability of Knowledge', 'Structure of Knowledge', and 'Value of Knowledge Acquisition' to reveal differences in sophisticated beliefs and naive belief levels. As a result, it was derived that Feynman's science lecture influenced pre-service teachers in terms of establishing new perspectives and recontextualizing existing epistemological beliefs. This study is meaningful in that pre-service teachers' scientific epistemological beliefs may vary depending on the situation, and that the scope and depth of epistemological beliefs may be expanded to include scientists' beliefs in science through disciplinary reading.

The purpose of this study is to synthesize the theoretical perspectives, research methods, and research results of teachers' professional vision by reviewing and analyzing previous research papers and to suggest implications for science teacher education and research. Three databases were used to search peer reviewed journal articles published between 1997-2017, which include 'teachers' and 'professional vision' explicitly in abstracts and empirical studies only. 21 articles in total were analyzed and review results are as follows. First, researchers regarded professional vision as a new concept of teacher professionalism. Previous research viewed professional vision as integrated structure of teachers' knowledge or ability activated at specific moment. Second, the analytical framework of professional vision included two aspects; 'selective attention' and 'reasoning'. Several aspects of lessons or the desirable teaching and learning factors are suggested as the subcategories of selective attention. Hierarchical levels or independent reasoning ability factors are suggested as the subcategories of reasoning process. Third, research on teachers' professional vision focused more on middle school teachers than elementary teachers and on various subject areas. Most studies used video clips and more cases of using videos of non-participants were found. In case of measurement of professional vision, most quantitative scoring methods were whether the responses of experts and teachers on video clips were consistent. Last, most studies examined or assessed teachers' professional vision. It is reported that in-service teachers' professional vision was evaluated higher than novice teachers' and using video clips were effective to examine and improve teachers' professional vision.

The purpose of this research is to direct the 7th national primary science curriculum to be performed properly. The research is based on the questionnaire to investigate the primary teachers' appreciation of the curriculum. The questions are about the general aspect of the 7th curriculum and special treatises on science curriculum. Questionnaires were distributed to 1000 teachers, and 822 teachers answered them. According to the survey results the teachers' thoughts were as following: First, there must be enough time to develop a new curriculum. It is not desirable to change the old curriculum totally. There should be some continuity between the old and the new curriculum. Second, teachers appreciated that the learning resources and supplements were helpful, and interested students. Teachers thought that If equipment at class or school was not enough. Third, according to them the hierarchical structure of science curriculum was appropriate, but the contents need to be improved. Fourth, most teachers restructured the 7th science curriculum to adapt it to the class and school. They cooperated with one another in teaching science, and applied diverse teaching-learning methods according to the curricular contents and the grade levels. Teachers tried to evaluate all aspects of the students with various methods, but they felt it was hard. They were not active in developing evaluation tools as a team, and in objectifying the information about students. Fifth, teachers felt it was hard to implement the science curriculum according to different levels of the students. Based on the survey of teachers' thoughts, the following can be suggested for successful implementation and reorientation of the curriculum. First, teachers need learning opportunities to appreciate and adapt the 7th curriculum creatively. Second, they need guidances in implementing the different levels of the curriculum, and the information about the appropriate resources for it. Third, we need to control the relative difficulty of the curricular contents, and reduce the hours and quantity of the study. Fourth, we need to improve the school equipment and facilities. Networking and cooperation among education-related institutions are essential for better education. Fifth, it is desirable to develop concrete and diverse teaming models.

The purpose of this study was to examine the pre-service elementary teachers' views on the necessity of science learning. The eighty five student teachers in their second year of studies were participated in this study. The participants freely wrote their thoughts on a question'Why should students learn science?' The results of the study are as follows: (1) The participants' responses were very diverse, so their responses contained almost all kind of values or arguments about the science learning suggested by researchers, and there was no difference in their response ratio between views of focusing on intrinsic values and views of focusing on extrinsic values; (2) About 30% of the participants had the biased conceptions on the necessity of science learning and they would be likely to explain their biased conceptions to their future students. The educational implications and the suggestions for further studies are also presented in this paper.
