  • The principal objective of this study was to assess the current status of elementary students' intake of dietary supplements, in an effort to diagnose any overnutrition, and to employ the results as basic data for the establishment of a balanced nutritional education. A survey was conducted by using a questionnaire administered to 734 elementary students’ parents in Seoul, and the analyzed results were as follows: Most parents believed that their nutritional knowledge was better than the norm(91.5%). However, almost half of the parents(49.2%) were feeding certain dietary supplements to their children, despite their perception that their children were already healthy, and were not recognizing any significant beneficial effects from those supplements. The most popular dietary supplements being fed were vitamin complexes. The majority of children took at least one type of dietary supplements at a monthly cost of approximately 10,000${\sim}$30,000 won. These results revealed the potential for overnutrition in some of the elementary students as the result of dietary supplement intake; thus, further studies involving assessments of risk for dietary supplement overconsumption in children and proper dietary education for the parents are suggested.

  • The purpose of this study was to survey the problem of teachers' narrative reporting of children's science learning in elementary school report cards. For the purposes of this study, a questionnaire, comprised of 6 questions and an analysis tool (Cronbach's $\alpha=.70$) were developed to categorize the answers. The survey was conducted by 53 teachers, who are currently taking 5th ade in elementary school, and the results are as follows: First, they interpreted the same content of report cards in a variety of different ways. Second, they exhibited a number of different principles and criteria in terms of preparing the content of narrative report cards. Third, they experienced difficulties in preparing narrative report cards on science teaming which required explanation of complete processes. Fourth, most teachers surveyed answered that the content of their narrative reports on science learning did not communicate specifically the students' achievement and further studies. Fifth, the activities related to preparing the content of the science learning on narrative reports was widely perceived to be useless for teachers' professional development. Finally, teachers made a number of alternative proposals to overcome the current, perceived problems of teachers' narrative reporting for children's science learning in report cards. Based on the results of this analysis, alternative forms and content of narrative reports on science learning were discussed.

  • The purpose of this study was to compare the biology contents of elementary schools science textbooks between Korea and Japan. To this end, the organization of subject matter and the type, process and context of inquiry activities were analyzed. The findings of this study were as follows: First, the sheer number of topics presented at each grade level was considerable and the contents of science textbooks were fixed in a set form in Korea. However, the organization and development of contents were made by considering the state of things and seasons in the case of Japan. Second, the amount of inquiry activities in Korea was higher, but the relationship between concepts and inquiry activities was lower than in Japan. Third, actually conducting (or 'doing') inquiry type activities was highest in Korea, on the other hand, 'experimenting' appeared to have a higher priority in Japan. Fourth, inquiry processes of activities in each country were very similar, in that the ratio of performing an inquiry was high, and perceiving a problem or designing an inquiry was low. Fifth, the results of analyzing the inquiry contexts of activities showed that the framework of evaluating inquiry activities based on curriculum objectives should be provided in the earlier stages of science textbook development.

  • The purpose of this study is to examine the effect of IIM-based science writhing lesson on the science process skills and self-directed learning in elementary science-gifted students. To verify research problems, the subjects of this study were forth-grade students selected from one classes of an elementary science-gifted class in Busan National Universty of education : the research group is composed of twenty students who were participated in IIM-based science writing lessons. During 12 weeks, the IIM-based science writing lessons was executed in the reasearch group. Post-test showed following results: First, the research group showed a significant improvement in the science process skill. We look into detailly this, the research group showed a significant improvement in the basis science skill. The sub-factor 'expectation' of the science process skill effects a significant improvement. Second, the research group showed a significant improvement in the self-directed learning. In conclusion, IIM-based science writing lesson was more effective on science process skill and self-directed learning. However, since the study has a limit on an object of the study and the applied program, the additional studies need to be conducted with an extended comparative group and program.

  • This study analyzed how characteristics of process-focused assessment are implemented in the distributed process-focused assessment examples in elementary school science education. To this end, through a review of previous studies, the analysis perspectives on the characteristics of the process-focused assessment were extracted into six categories. Using the analysis framework, it was described how process-focused assessment examples in elementary school science education developed by metropolitan office of education reflected the characteristics of process-focused assessment. As a result of the study, the characteristics of process-focused assessment were often formally reflected in sample materials. For example, there was a lack of skills on how to effectively integrate instruction and evaluation in practical terms. In many cases, feedback simply induced a recall of a learned concept or simply guides a related scientific concept. In some cases, the characteristics of process-focused assessment did not appear prominently in the sample materials. Also the developed sample materials were divided into the same type as the existing science and performance assessment questionnaire, a narrative·essay type, and a type similar to experimental workbook.

  • Dimensions of learning, based on the vast studies on teaming psychology and teaming processes, have been played an important role as one of the frameworks of curriculum and teaming strategies. Dimensions of Learning consist of 5 Dimensions, each of 'Attitudes and Perceptions', 'Acquire and Integrate Knowledge', 'Extend and Refine Knowledge', 'Use Knowledge Meaningfully', 'Habits of Mind'. And each dimension has $3\~8$ lower categories in itself, The elementary 5th grade science lesson emphasizing upon Dimensions of Learning was developed in this study. The lessons dealt with almost every lower categories of Dimensions of learning. We analysed students' scientific attitude and scientific achievement quantitatively after the lesson emphasized upon Dimensions of Learning in comparison with typical lesson laying stress on teachers' guides. The results are as follows; Students' scientific attitude was significantly changed after the lesson emphasized upon Dimensions of Learning. The willingness, positiveness, straightforwardness, and openness of lower categories of students' scientific attitude were more significantly changed especially. But students' scientific achievement was not significantly changed after the lesson emphasized upon Dimensions of Learning.

  • For decades, reflection has been recognised as a meaningful tool to bring forth teachers' ownership as well as knowledge and action empowerment in teacher education. Yet there have been few studies on elementary teachers' reflection on their science teaching in Korea. In this study, 71 reflective journals of 24 elementary teachers on their science teaching were analyzed. The characteristics of reflective journals were analyzed in terms of 'productive reflection', a concept suggested by Davis (2006). Unproductive reflection is mainly descriptive without analysis, whereas productive reflection can promote teachers' learning by integrating four aspects of teaching (learner/learning, subject matter knowledge, instruction and assessment). The result showed what elementary teachers consider and emphasize and how they integrate their ideas. Most of reflective journals included aspects of 'instruction', 'learner/learning', and 'subject matter knowledge'. However 'instruction' was emphasized most frequently (69.0%) than 'subject matter knowledge' (33.8%) and 'learner/learning' (26.8%). 'Assessment' was hardly included nor emphasized. More than half of the journals (56.3%) showed no integrations, which were unproductive reflection. A third of the journals (32.4%) integrated only two aspects among four. Average score of integrations was 1.6 on a scale of 4 points. The integrations were not affected by the length of reflective journals and the teaching experience. These findings suggest that productive reflection would not increase naturally with teaching experience and there needs more tactful guidance to develop elementary teachers' productive reflection on their science teaching.
