  • The purpose of this study was to explore characteristics of sixth grade students' opistemological beliefs in science and the relationship to learner's characteristics: learning motivation, learning strategies, and logical thinking. The subjects were 265 sixth graders and data was collected through two types of questionnaires, translated and modified by researchers: opistemological beliefs regarding science, learning motivation & strategies. The results of this study were as follows. The students believed that the goals of science were related to activations such as 'Science is experiment', or 'Science is invention: These beliefs were connected with the emphasis of science classes or the focus of the science curriculum. However, the students' beliefs related to the changeability of science knowledge, the source of science knowledge, and the role of experiments in developing knowledge were oriented to modern opistemological views. Moreover, the beliefs were meaningfully related to students' characteristics: learning motivation, learning strategies, and logical thinking. Among the students' characteristics, logical thinking was especially related to all of the factors of students' beliefs: the changeability of science knowledge, the source of science knowledge, and the role of experiments in developing knowledge. However, the students who believed that scientific knowledge came from scientists, science teachers, or science textbooks had high levels of self-efficacy. Therefore, the belief that scientific knowledge is formed by self-discovery, in order to generate high self-efficacy, needs to be encouraged. From the results, it is possible to check the orientation of current science education based on the students' opistemological beliefs. In addition, the resources can be accumulated for persevering in our efforts to achieve a positive orientation for science education.

  • The purpose of this article is to develop a dynamic model of organizational capabilities and knowledge creation, and at the same time identify the organizational capability factors for effective knowledge creation, by empirically analyzing the history of new Quinolone antibacterial drug compound (LB20304a) discovery process at LG, as a case in point. Major findings of this study are as follows. First, in a science-based area such as drug development, the core of successful knowledge creation lies in creative combination of different bodies of scientific explicit knowledge. Second, the greater the difficulty of learning external knowledge, the more tacit knowledge is needed for the recipient firm to effectively exploit that knowledge. Third, in science-based sector such as pharmaceutical industry, the key for successful knowledge creation lies in the capability of recruiting and retaining star scientists. Finally, for effective knowledge creation, a firm must keep its balance among three dimensions of organizational capabilities: local, process, architectural capabilities.

  • 이 연구의 목적은, 과학교육을 위해 과학적 세계관을 기반으로 하여 다양한 과학이론들이 철학적으로 어떤 위치에 있는지를 탐색하는 것이다. 또한 그동안 통상적으로, 인식론과 방법론을 주로 다루어왔던 과학교육을, 존재론, 즉 형이상학의 믿음의 문제로 확장시키는 것에 목적을 두고 있다. 전통적으로 우리의 마음과는 독립적으로, 고정되고 변화하지 않는 객관적인 과학지식이 존재한다는 형이상학적 믿음의, 강한 결정론으로 정의된 물리적 실재론이 존재한다고 할 수 있다. 이것은 Newton, Einstein, Schridinger가 정립한 동역학의 자연법칙에서 볼 수 있는 것으로 '수학 화'라고 할 수 있다. Einstein도 상대성이론을 통하여 전통적인 견해를 어느 정도 흔들어 놓았으나 그의 이론은 여전히 전통적인 사고에 가까웠다. 이와는 반대로, 이러한 엄격한 결정론으로부터 벗어나게 되면 '가능성', '우연'과 같은 의인화 된 개념이 필요하다. 고전적으로 강한 결정론적 사상으로부터 약한 결정론인 우연적인 사고인 확률론으로의 변화와 자연주의적 관점으로 과학이론의 변화를 주도하는 현대의 과학적 세계관의 특징이다. 이는 Darwin의 진화론과 양자역학에 해당한다고 할 수 있다. 우리는 이러한 존재론적 세계관을 정당화하는 세 종류의 인식론적 세계가 있다고 말할 수 있다. 바로 합리주의, 경험주의 그리고 자연주의다. 과학교육은 우리가 교육현장에서 다루는 과학 이론이 어떤 형이상학적 믿음에 기반을 두었는지 많은 경우 말하고 있지 않다. 또한 과학교육은 과학 지식의 이해에만 초점을 맞추고 있다. 그러나 학습한 지식의 앎이라는 것과 학습자 자신의 형이상학적 믿음인 세계관과 연결되어 있을 때만 진정한 지식을 이해를 가져올 수 있다고 할 수 있다. 따라서 앞으로 과학교육은 다양한 과학이론들을 과학적 세계관과 철학적 위치에 기초하여 연결시키고 이를 학생들에게 제시해줄 필요가 있다.

  • This study has been performed in order to achieve three objectives. They are as follows: To analyze, based on the research literatures, the nature of scientific inquiry ability and the characteristics of its constitutive elements. To identify inquiry skills and techniques essential to such areas as physics, chemistry, biology, and earth science. To develop instructional models and materials for enhancing inquiry ability on the part of high school students. It was found in the study that the scientific inquiry was interpreted in terms of different meanings according to the viewpoint of the person who are interested in the nature of science. The scientific inquiry has been viewed as the process of knowledge formation, scientific method, inquiry process or process skills depending on the epistemological, methodological, educational perspectives, respectively. It was also identified that certain kind of skills or techniques would be used for inquiry in only one specific area of the science. The skills and techniques are effectively learned when those are taught with specific knowledge in each area of the science. The model and materials for fostering scientific inquiry skills will be presented on the second part of the report.

  • The science writing is recognized for useful learning method to boost up scientific thinking for all class course as well as traditional lecture and experiment. Many researches say that science writing is helpful to extend students' science knowledge and scientific attitude. By the way, the researchers thought that science writing can also improve the science process skill if students participate in delicately organized learning program. In this study, we had contrived the teaching & learning strategy of science writing to improve science process skills. The learning program covers all field of Klopfer's process skills with various forms of writing; explaining writing, logical writing, critical writing, and creative writing. The learning program has been developed for 5th grade students in the regular classes in order to enhance science process skills as well as knowledge and scientific attitude. Not to miss any process skill or various kinds of writing, we used 3 dimensional frame. The axes of the frames are science process skills, forms of writing, and science curriculum contents. The students are given the final writing theme at the beginning of each chapter. They drill science process skills step by step during the classes, and have a chance to talk each other before the final writing. They practice writing skills from one sentence to full article by degrees. The effect of the program was examined by students' work and TSPS (Test of Science Process Skill). The result showed that 5th grade students had a meaningful progress in science process skills as well as knowledge and scientific attitude. we could confirm it with examining students' work in the class.

  • For effective science learning, teachers need to rearrange scientific language so that students can understand the contents with their incomplete language resources. Interlanguage is the interplay between everyday language and scientific language. The purpose of the study was to analyze the patterns of interlanguage during 4th grade science class to learn "Heat and Temperature" and to find the features of meaning sharing inside classroom in which a teacher and students participated. The data analysis shows that elementary students' interlanguage has different features compared to scientific language that involves passive voice and content-specialized nouns. Students' interlanguage implied the quality of class community's knowledge-sharing, according to the degree of how students can connect scientific language and everyday language in more effective ways. The implication to elementary science education was discussed.

  • The purpose of this study was to investigate inservice elementary teachers' view and the change of preservice elementary teachers' view on the nature of science by the science education course. The subjects were 386 junior preservice teachers in a National University of Education and 257 inservice teachers working in a metropolitan city. An instrument consisting of fifty eight items were developed on the bases of previous studies. Before entering the course, preservice teachers view was compared by gender with T-test and no significant differences were found except the category 'role of a scientist'. Preservice teachers view was also compared by major with ANOVA and significant differences were found on the categories 'scientific method' and 'scientific law'. After the course, on comparing their view by gender, significant differences were found on the categories 'scientific theory', 'scientific knowledge', and 'scientific law'. The result of ANOVA by major, significant differences were found except the category 'role of a scientist'. Inservice teachers view was compared by gender and major and the differences were no significant, the significant differences, however, were founded in comparing by career and ability.
