  • The purpose of this investigation was to examine and compare pre-service and in-service elementary school teachers' beliefs about Science-Technology-and Society (STS), particularly beliefs about the nature of science and technology, their interaction within society, and the epistemology of science. Large percentage of pre-service and in-service elementary school teachers were understood to perceive as follows : 1. they regarded the science as 〃Knowledge scheme aiming content'and technology as 'skill for solution of actual problems'. 2. they revealed themselves to perceive tat science/ technology influence our lives through new terms and ideas, that science/ technology is affected by governmental policies and that all the people concerned including scientist and technologist should participate in the course of decision making. 3. they perceived that scientist perform their studies by characteristic abilities and that the studies are affected by their religious viewpoint. Moreover, they were understood to perceive that scientific knowledge are constructed through social interaction. 4. they perceived that scientist discover and develop scientific laws by scientific methods such as verification and certification, and that those scientific laws could be changed later.

  • Just after decolonization in 1945, there was no basic research in Korea representing only 12 PhD's and about 300 college graduates of science and technology areas. Now, the symbols of basic scientific research have been developed to 66,000 university researchers in science and technology area and 36,000 SCI papers. The government can be credited as playing the most important role in such development, but there are no studies about what are the process and details of the policies. 1his paper examines the flow of major events in the basic scientific research through government policies suggesting a chronological table. The selection and checking of each event were supported by two other experts besides two authors. We divide policies for basic scientific research with policy infrastructure, administration system, and policy subject. Policy subject is further divided into research environment, research infrastructure, and human resources. The results are threefold. We show that basic scientific research has progressed over 5 stages of development, and 15 significant incidents has occurred. Also, major events were done not solely by the government, but also the requests by researchers. Scientific society has continually put the impetus on the government.

  • The purpose of this study is to analyze science fields and content elements of the science reports in a web portal site of Republic of Korea in view of scientific literacy. The main results of the analysis on the 679 reports sampled in a year are as follows. First, 506 reports in 46 fields were identified. Reports about technology and earth science occupies 16% respectively, and life science occupies 13%, medical science 4%, chemistry, company, others 3% and physics 1%. Almost reports show technology as associate field. Second, the frequency rate of reports including scientific literacy content elements is 52%. Reports related to 'physics' and 'chemistry' as dominant fields show relatively high rate in scientific literacy elements. The element, 'social context' is included in about 96% of the reports. Both 'data and statistics' and 'application' show relatively low rate and large gaps according to dominant fields. A few concluding remarks and proposals follow from these results. First, as almost science reports show the nature of integrated science, scientific literacy acquisition through science reports in internet requires the integrated scientific view. Especially most science reports includes the contents related to technology or medical science, so the point of view in the science-technological literacy is required. Second, the scientific literacy content elements in reports show various rates according to dominant fields. Therefore, science reports need to complement the deficient content elements to carry out the role of science reports as scientific literacy sources.

  • Understanding the nature of science (NOS) has been a major component of scientific literacy and an important learning goal in science education (American Association for the Advancement of Science, 1990, 1993; Millar & Osborne, 1998; National Research Council, 1996, 2013). To achieve this goal, it is necessary to include appropriate views of the nature of science in science curriculum such as a textbook. The aim of this study was to conduct a content analysis of the elementary science textbooks to examine the presentation of the nature of science (NOS) using the four themes of scientific literacy, which are (1) nature of scientific knowledge, (2) nature of scientific inquiry, (3) nature of scientific thinking, and (4) nature of interactions among science, technology, and society (STS). Findings show while $3^{rd}$ and $4^{th}$ grade levels of science textbooks heavily emphasize on the Theme I, nature of scientific knowledge and the Theme II, the nature of scientific inquiry, the upper grade levels such as $5^{th}$ and $6^{th}$ grades of science textbooks are well balanced with the four themes of the nature of science. In addition, most of elementary science textbooks little focus on the Theme IV, nature of interactions among science, technology, and society (STS) among the four themes of the nature of science. It might be a shortcoming because the understanding the nature of interacions among science, technology and society (STS) is one of the key components in order for students to be a scientific literate person.

  • 20 preservice teachers at college level participated in this study and interacted with students at elementary and middle school levels during science camp offered by science center in Taiwan. Preservice teachers displayed moderate (above the average, 4 point out of 5) understandings about scientific literacy and scientific views in all aspects of the nature of science before the camp. Then, the researchers designed science camp programs which were expected to promote students' scientific literacy; scientific knowledge, inquiry skills for experimentation as well as for argumentation, affective domain such as the attitude toward science and the understandings about nature of science and the relationship among STS (Science-Technology-Society), all of which were embedded in the programs. Preservice teachers seemed to perceive scientific literacy pretty well (over 4 point) before the camp, however, preservice teachers' understandings about scientific literacy were not much scored (around 3 point, but still moderate scores of average) as expected after concrete inquiry activities. The reasons why this happened could be that preservice teachers were not trained to employ theory into the context to be more practical or the researchers did not develop camp program which included the aspect of scientific literacy successfully. The discussion and implication were made in teacher education in that preservice teachers must be prepared how to bridge theory into practice, and informal science education in that educators at science centers must be trained to be experts in providing the envisioned educational programs to meet the goal of science education, scientific literacy.

  • Despite extensive research, performance enhancement of keyphrase (KP) extraction remains a challenging problem in modern informatics. Recently, deep learning-based supervised approaches have exhibited state-of-the-art accuracies with respect to this problem, and several of the previously proposed methods utilize Bidirectional Encoder Representations from Transformers (BERT)-based language models. However, few studies have investigated the effective application of BERT-based fine-tuning techniques to the problem of KP extraction. In this paper, we consider the aforementioned problem in the context of scientific articles by investigating the fine-tuning characteristics of two distinct BERT models - BERT (i.e., base BERT model by Google) and SciBERT (i.e., a BERT model trained on scientific text). Three different datasets (WWW, KDD, and Inspec) comprising data obtained from the computer science domain are used to compare the results obtained by fine-tuning BERT and SciBERT in terms of KP extraction.

  • This study aims to analyze the content and methodological aspects of converging scientific technology and humanities in 233 elementary school STEAM programs developed and publicized from 2012 to 2015, to provide the basic materials and implications for editing and supplementing the development of future STEAM programs or policies, or on-site applications of developed programs. The analysis results show that among the Liberal Arts courses of the STEAM program, including Korean, Social Studies, and Ethics, the level of convergence was lowest in Ethics. This seems to be due to the fact that convergence between scientific technology and humanities tended to emphasize a cross-studies convergence over a content convergence done with a specific purpose. In terms of methodological convergence between scientific technology and humanities, the level of convergence of humanities at a normative level was relatively lower than that at a descriptive level. Although a quantitative comparison of the two methods was not significant, it is rather concerning that due to simply converging descriptive humanities, students may not be so aware of the double-sidedness of scientific technology, despite the discovery of some programs that need re-evaluations of their ethical or normative directions. Moreover, the results showed that the cases of converging scientific technology and humanities at a normative level that were analyzed in the STEAM program can be divided into 'complementation of humanities to utilizing scientific technology' and 'complementation of humanities to research in scientific technology and development.' Based on such research results, the study discusses the development of STEAM programs and policies and directions for editing and supplementing programs on-site.

  • D. J. Haraway's cyber-feminism and Kim Seon Hee's eco-feminism are so different in the perspective of the modern scientific technology. While cyber-feminism thinks the outcome of the modern scientific technology positively, eco-feminism criticizes the totalitarianism and the human negation which the modern scientific technology gives rise to. Cyber-feminism gives us an image of the future female, but exposes an easygoing way of thinking of the modern scientific technology. On the other hand eco-feminism takes notice of the risk, that the modern scientific technology can be abused by the power of the minority, but fails in overcoming of the traditional view of female.

  • In this study, we investigated the elementary school students' perceptions of the scientific and technological professions by using the 'drawing scientific and technological workplaces'. The subjects were 401 students of 4th and 6th grades at three elementary schools in Seoul. The results revealed that many students drew the interiors of laboratories or factories as scientific and technological workplaces, and explained the nature of the work- place, but students' images were superficial and general. Most students' drawings also exhibited the stereotypical images of science and technology as androcentric and negative perceptions. Students were mainly inclined to perceive that the works relevant to science were experiments, and the works relevant to technology were productions and repairs. Most students answered more than two examples of scientific and technological professions, but their responses were not various and were biased toward basic scientists, blue-collar workers, and repairers. Educational implications of these findings were discussed.
