The purpose of this study was to examine the management status of science in senior high schools based on the 2009 Curriculum Revision and the science teachers' perception of the content and a class of science. The way of managing a class was surveyed and discovered that the percentage of more than two teachers giving lessons depending on their major was higher than that of a teacher giving all the lessons. Analysis of teachers' perceptions of the content of science showed that science textbooks reflected the revised science curriculum well. However, teachers thought that the terms and concepts introduced to describe the knowledge of frontier science were so difficult that they feel it's very hard teaching them to the students. Even though science teachers thought that science was mainly focused on cultivating scientific literacy of the students, they assess mostly understanding of science concepts on the students. It means that science teachers stay in line with old position in assessment.

Heavy metals can be intentionally or unintentionally introduced into plastic food utensils, containers, and packaging (PFUCP) as additives or contaminants, which can be ingested with food by humans. Here, seven-heavy metals (lead, cadmium, nickel, chromium, antimony, copper, and manganese) with toxicity concerns were selected, and risk assessment was done by establishing their migration from 137 PFUCP products made of 16 materials distributed in Korea. Migration of heavy metals was examined by applying 4% acetic acid as a food simulant (70℃, 30 minutes) to the PFUCP products. Inductively coupled plasma mass spectrometry (ICP-MS) was employed for the analysis of migrated heavy metals, and the reliability of quantitative results was confirmed by checking linearity, LOD, LOQ, recovery, precision, and expanded uncertainty. As a result of monitoring, heavy metals were detected at a level of non-detection to 8.76 ± 11.87 ㎍/L and most of the heavy metals investigated were only detected at trace amounts of less than 1 ㎍/L on average. However, antimony migrated from PET products was significantly higher than other groups. Risk assessment revealed that all the heavy metals investigated were safe with a margin of exposure above 311. Collectively, we demonstrated that heavy metals migrated from PFUCP products distributed in Korea appear to be within the safe range.

In this study, we investigated the influences of Integrated Science on the views of 10th graders with regards to the nature of science (NOS), STS, interest in science, and science aspiration, in order to explore the effects of Integrated Science developed under the 2009 Revised National Curriculum. Participants in this study were 214 10th graders in Seoul. The survey was administered at the beginning and at the end of the Integrated Science course. The analyses of the results revealed that there was no statistically significant difference in the scores of the pre-test and post-test on the NOS survey. However, the post-test scores of the tentativeness of scientific knowledge and the use of imagination, which are the sub-constructs of the NOS, were found to be significantly lower than the pre-test scores. There were no statistically significant differences in the frequencies of the responses to each item of the STS survey. The pre-test and post-test scores of the interest in science and the science aspiration were also not significantly different. The results indicated that Integrated Science did not have any impact on students' views on NOS, STS, interest in science, and science aspiration. Educational implications of these findings are discussed.

The purpose of this study is to explore the research trend changes of convergence education since 2011 compared to the convergence education research that has been steadily continuing in science education. The trend in convergence education were investigated by comparing the number of publications, research subjects, research content, and topic linkages with previous studies, and using the network analysis method to check recent research trends. In the field of science education, the number of papers related to convergence education has been published more than 8.0% steadily, and it has been increasing since 2012, then decreasing again from 2015 and gradually increasing again from 2017. The subjects of study were high in elementary school students, while those in middle school, high school, and university students were low. While the number of in-service teachers increased, the number of pre-service teachers decreased, and the literature and public increased somewhat. In study content, effectiveness studies decreased, while development studies increased, and theoretical and perception studies appeared similar. In thematic linkage, the intra-science linkage was 23.9%, and the extra-science linkage was 76.1% and engineering/technology and art were high in extra-science linkage. In network analysis, elementary, science, STEAM, and program words have a high frequency of appearance and appear together with other words to lead the network. The educational implications of the research trend of convergence education will be more emphasized in the field of science education in the future, and in order to take root in the education field, research on secondary students should be more actively studied. In addition, it is necessary to move away from research on STEAM-centered program development and effects, and to increase research to establish the philosophical basis and theoretical of convergence education.

The purpose of this study was to develop "Movie Production Project" Science-Arts convergence STEAM program for elementary students and investigate the effects of the program on career orientation of science, career awareness and creative personality. Participants were 82 elementary school students. The results of this study were as follows: First, experimental group's total score of career orientation of science was significantly higher than that of comparative group. Among sub-areas, science learning preference, science career preference and perception on science career worth were significantly different between two groups. Experimental group's scores were significantly higher than those of comparative group. Second, experimental group's career awareness total score was significantly higher than that of comparative group including all sub-areas. Third, experimental group's creative personality total score was significantly higher than that of comparative group including 2 sub-areas, independence, openness. Finally, experimental group student's perception on the program showed that it was interesting, a little easy and they hoped to study again.

The research aims to verify the effects of preference for science and self-directed learning ability of the science puppet show program that the researcher has developed as a STEAM education model. The results for conducting the survey with the same questionnaire before and after the program targeting the students showed that the science puppet show had effects on increasing the science related assignment performance will of the behavioral will among the three sub-dimensions including emotional respond, value cognition and behavioral will, but there was no effect on overall aspects of science preference. It can be interpreted as reflecting the characteristics of the scientific talents who already have a high level of preference for science. In addition, the three sub-dimensions including the cognitive regulation, motivational regulation and behavioral regulation had effects on the self-directed learning ability. Especially it had great effects on the directed learning ability of cognitive regulation, learning motivation of motivational regulation, tool application of behavioral regulation, and cooperation capacity which were greater for female students than male students. It is judged that the three-staged science puppet show program including the 'content integrating stage' that the students integrate the curriculum contents, 'integrated mission stage' of solving the visualization, auralization and performance missions by themselves, and 'process integration stage' of making the stage piece all together.

In the era of the 4^th industrial revolution and convergence, various discussions and studies have been conducted to develop future social talents, and through this, the need for creative convergence talents is increasing. In line with the change to a software-oriented society, countries around the world are trying to strengthen SW education, but high school students' awareness of the necessity of information subject and SW education that is the center of convergence is insufficient. Therefore, opportunities for convergence of the information subject and various fields should be provided. In this study, information education was converged to the science exploration experiment subject to construct an educational program that can develop creative convergence, and a convergence class using physical computing were applied to high school students for 9 hours. As a result of the experiment, the recognition of SW education of the experimental group was improved, and it was confirmed that the learner's convergence literacy of the experimental group was statistically different from that of the control group that conducted the general science experiment class.

The citation information of academic resources contains the knowledge flow from previous research, so it is possible to connect fragmented research in relational aspects. The citation information can grasp the overall flow of research, so it can promote convergence research such as developing existing research or deriving related fields. Therefore, in this study, the citation information of academic literature, which was previously provided at the level of simple disclosure, was reconstructed based on the citation relationship. Through this, backward and forward citation analysis were conducted based on time series, and the research flow was analyzed by setting the citation stage. Finally, we developed an academic information service that visualizes the main research contents of backward and forward citation based on time series. This accesses academic resources through the meaning contained in the citation information.
