Data mining and knowledge discovery techniques have shown to be effective in finding hidden underlying rules inside large database in an automated fashion. On the other hand, analyzing, assessing, and applying students' survey data are very important in science and engineering education because of various reasons such as quality improvement, engineering design process, innovative education, etc. Among those surveys, analyzing the students' views on science-technology-society can be helpful to engineering education. Because, although most researches on the philosophy of science have shown that science is one of the most difficult concepts to define precisely, it is still important to have an eye on science, pseudo-science, and scientific misconducts. In this paper, we report the experimental results of applying decision tree induction algorithms for analyzing the questionnaire results of high school students' views on science-technology-society (HS-VOSTS). Empirical results on various settings of decision tree induction on HS-VOSTS results from one South Korean university students indicate that decision tree induction algorithms can be successfully and effectively applied to automated knowledge discovery from students' survey data.

이 연구의 목적은 STS에 대해서 우리 나라 고등학생들이 가지는 견해를 알아보기 위한 평가 도구인 HS-VOSTS(Korean Students' Views on STS)를 개발하는 것이다. HS-VOSTS 문항을 개발하기 위해서 다음과 같은 연구과정을 수행하였다. 우선, 문헌과 선행 연구 고찰을 통해 4가지 범주의 10가지 하위 범주와 관련하여 23개의 논제를 포함하는 STS 범주 체계를 설정하였다. STS 범주 체계는 정의 과학의 외적 사회학 과학의 내적 사회학 인식론의 네 가지의 커다란 범주로 구성되어 있다. 다음은 STS 범주 체계를 기초로 4단계에 걸쳐 문항을 개발하였다. 1단계에서는 각 논제에 대한 짝진술문을 기초로 학생진술 문항지를 작성하여 772명의 고등학생들(16.3세)에게 투입하였다. 2단계에서는 짝진술문 중 하나를 제거하여 문항의 진술문으로하고, 분류된 공통견해를 답지로 하여 1차 다지선다형 문항지를 구성하였다. 3단계에서는 고등학생 28명(16.5세)을 대상으로 반구조화 면담을 실시하여 그 결과 분석을 통해 2차 다지선다형 문항지를 구성하였다. 4단계에서는 2차 다지선다형 문항지를 고등학생 306명에게 적용하여 낮은 반응비율을 보인 답지들을 제거하여 최종 검사도구를 완성하였다. HS-VOSTS는 학생들의 STS에 대한 신념 및 견해를 알아볼 수 있는 유용한 도구로서, 그 결과는 교사뿐만 아니라 교육과정 개발자, 교과서 저자, 교육정책 입안자들에게 많은 시사점을 줄 수 있을 것이라 생각한다.

In order to study the effect of the 'General Science' course implemented under the 6th science curriculum, high school students' views about the relationship between science/technology and society and their perceptions of science classroom environment were investigated. Four classes (n = 211) were selected from those completed the 'Science I' course under the 5th science curriculum, and 4 another classes (n = 216) which took the 'General Science' course under the 6th science curriculum were selected. In order to compare students' views about the relationship between science /technology and society. 10 items were selected from the VOSTS (Views On Science-Technology-Society) while considering the 6th science curriculum and the 'General Science' textbooks, and administered at the end of the 'Science I' course and at the beginning and end of the 'General Science' course. In order to compare the perceptions of science classroom environment, the Perceptions of Science Classroom Environment Questionnaire, which was prepared from the Individualized Classroom Environment Questionnaire. the Science Laboratory Environment Inventory, and the Classroom Environment Scale. was also administered at the end of the 'Science I' course and the 'General Science' course. The results indicated that the mean VOSTS score of the 6th-curriculum group was lower than that of the 5th-curriculum group, although the difference was not statistically significant. The decrease in the VOSTS score of the 6th-curriculum group during the 'General Science' course was statistically significant. It was also found that unrealistic views such as 'technology is the application of science', and 'corporations should control science/technology' had been formed during the course. However, the 6th-curriculum group had more positive perceptions of science classroom environment. Educational implications are discussed.

본 연구의 목적은 과학 영재의 STS에 대한 견해를 알아보기 위한 것이다. 134명의 과학 영재들에게 다지선다형인 HS-VOSTS 검사지가 시행되었다. 연구 결과 과학 영재들은 기술을 과학 지식을 실생활에 응용하는 것이라는 견해를 견지하고 있었다. 특히 과학 이론에서 문제점이 발견되면 수정해야 한다는 견해를 나타냄으로써 과학 지식의 잠정성에 대해 매우 높은 인식 수준을 보였다. 과학 영재들은 정부가 과학자들의 연구를 통제하지 말아야 한다는 데 다수가 동의했고, 연구 성과물의 긍정적 영향과 부정적 영향에 대해 과학자들이 고려해야 한다고 강조했다. 또한 학교에서 배우는 과학내용이 일상생활의 문제 해결에 도움이 되지 않는다는 의견이 높게 나타났다. 과학의 정의, 과학의 외적 사회학, 과학의 내적 사회학, 인식론에 있어서 과학 영재들의 인식은 성별에 따라 유의미한 차이를 나타내지 않았다. 이 연구는 향후 과학 영재 교육 프로그램과 교육과정 개발을 위한 시사점을 제공할 것이다.

Recent literature in science education has emphasized nature of science in science teaching. The theme has been considered to be an important element for scientific literacy.The purpose of this study was to identify Korean science teachers' points of view on topics related to nature of science, such as definition of science, characteristics of scientific hypotheses, scientific theories and scientific laws, and their construction, scientists, and scientific methods. The relevant 13 items were selected from Views on Science-Technology-Society (VOSTS) by the authors for this study. Most teachers perceived science as an exploratory process or problem solving. Some perceived science as an application of knowledge to make this world a better place to live in. Teachers viewed scientific activities as scholastic and individualistic instead of pragmatic or collective. They did not hold clear understandings of the idea that scientific knowledge is subject to change. As identified in previous studies, teachers thought that scientific ideas develop from hypothesis to theories, and finally to scientific laws. They did not show sound understanding of inventiveness of scientific hypotheses and theories, nor discovery of scientific laws. In summary, teachers' major points of view reflected 'realism'. It suggested that they needed to understand nature of science in the ways which it has been described in recent literature of science education, in order to teach science with personal and social contexts.

The study purported to develop STS education course material at the university level in order to enhance science literacy and understanding of the relationships among science, technology and society. A developed STS course was provided to 265 freshmen and sophomore students, majoring in the Humanities and the Social Sciences, the Natural Sciences and Engineering, and Fine Arts. Students participated in the survey examining changes in students' attitudes toward and perspectives on STS before and after the implementation. Ten questionnaires were selected from VOSTS for the survey. One additional questionnaire asked the students to elaborate their opinions on the need for a STS education course. The responses to the survey were analyzed according to types of questions and students' majors. As result, the developed STS course significantly increased students' science literacy. Among the participants, 97.7% responded that there is a need for STS education and provided reasons for such need. These results imply that there is a definite need for a STS class at the university level. According to the analyses of responses, there were different responses depending on the students' major. These differences imply that the major, academic background, level of interest in science, and knowledge of science of the students affect their perceptions on identifying the need for a STS education course.

The aim of this study was to identify students' views on the orientation of science and to investigate the relationship between their views and decision-making on socio-scientific issues (SSI). In this study, 27 university students attending a science course were asked to discuss four controversial issues: the Toyota recall, the green car, the global warming and swine influenza (influenza A (H1N1)). The study was comprised of two stages. At the first stage, we examined students' views on the nature of science and on the orientation of science with the open-ended questionnaire based on VNOS and VOSTS. While they held relatively similar views on the nature of science, their views on the orientation of science were distinct as pragmatic, intrinsic, communal and ethical views. At the second stage, to examine the role of their views on the orientation of science in decision-making, we selected four students who had similar views on NOS but different views on the orientation of science. The four students were selected from each group of views on the orientation of science and their decision-making processes were analyzed following grounded theory. Across SSIs, they relied upon their views on the orientation of science as the strategies for decision, though considered different perception, and causal and contextual conditions. This study indicates that understanding students' views on the orientation of science would be helpful for achieving scientific literacy for informed decision.

Various modern social problems are also related with science and technology. Thorough understanding about Technology-Society(STS) interactions is required to take informed action about how to deal effectively with these problems. In this case, there is a need for STS education. The purpose of this study was to examine the perceptions of high -school students and science teachers about Technology-Society interactions and differences of their perceptions. It is my hope that this thesis will contribute to future "General Science" class in Korea. We obtained the data by a survey of 414 high school students who took "General Science" courses in Seoul and 54 of their science teachers. The survey was made using 10 multiple-choice items selected from the VOSTS (Views On Science-Technology-Society) item pool. The results of this study are as follow: 1. More than half of the students and teachers thought that science is exploring the unknown and discovering new things. Their perceptions about the science are somewhat stable, but about the technology various. 2. Most students and teachers thought that science and technology interact and complement each other. They also thought that the improvement in the quality of life needs investments in both science and technology 3. Most students and teachers thought social facts as community, government, and politics influenced scientists and scientific research. They also had a good understanding about the effects of science and technology on society. We can conclude from this that they had a Science-Technology-Society oriented viewpoint. 4. There are significant differences between the perceptions of boys and girls in following categories (p<.05): Influence of Community or Government Agencies on Scientists Influence of Politics on Scientists Role of Scieoce/Technology in Resolving Social Problems 5. There are significant differences between the perceptions of students and teachers in following categories (p<.05): Definition of Science Influence of Politics on Scientists
