  • This paper proposes a noble service architecture based on scientific infographic as well as semi-automatic knowledge process for 'KISTI's Scent of Science' database, which has been highly credited as a science journalism service in Korea. Unlike other specialized scientific databases for domain experts and scientists, the database aims at providing comprehensible and intuitive information about various important scientific concepts which may seem not to be easily understandable to general public. In order to construct a knowledge-base from the database, we deeply analyze the traits of the database and then establish a semi-automatic approach to identify and extract various scientific intelligence from its contents. Furthermore, this paper defines a scientific infographic service platform based on the knowledge-base by offering its detailed structure, methods and characteristics, which shows a progressive future direction for science journalism service.

  • This study focused on research that illustrates the important interplay between learners' epistemological beliefs about science knowledge, physics textbook knowledge and knowing physics in the classroom. Also this study investigated learners' conceptual changes on the value of mechanical energy. To explore these topics, six sophomores were chosen as participants. Three categories were introduced to classify how participants' understanding of the nature of science knowledge, physics textbook knowledge has been linked with epistemological beliefs of knowing physics. The three categories were (1)receiving physics knowledge as authority, (2)receiving physics knowledge as the perception of teacher's role and (3)understanding physics knowledge as the perception that science knowledge is a product of a variety of human ideas. These categories were also concerned with construction of individual conceptions of mechanical energy. The participants who understood physics knowledge as the perception that science knowledge is a product of a variety of human ideas naturally used metacognitive strategy in classroom compared to other participants. And they had scientific conceptions about the value of mechanical energy. Others who were passive in classroom had unscientific conceptions about the value of mechanical energy due to definition of energy and epistemological beliefs about the nature of science knowledge. In the process of their conceptual changes on the value of mechanical energy, it was important to understand an instrumental aspect of scientific knowledge and to think about the relation between formulae and physical phenomena.

  • The purpose of this study was to explore how an elementary school teacher developed PCK by utilizing her knowledge domains in teaching practice, regarding the specific science topic of 'animals:' A case study approach was adopted with the participation of a 1st grade teacher, in a poor urban neighborhood elementary school in NYC. Data was collected through interview and the participant observation method in order to investigate: a) the teacher's existing knowledge base in terms of subject matter knowledge, pedagogical knowledge and contextual knowledge; b) how she develops PCK during classroom practice, centering on the relationship between knowledge domains. The findings illustrate the ways in which the three knowledge domains are closely related and developed as PCK through the whole teaching process. In particular, the findings indicate that the teacher's contextual knowledge plays a critical role in shaping and developing PCK. Before instruction, her contextual knowledge regarding the administrative policies and the school test system in the district enabled her to make decisions and plans about teaching science. During classroom teaching, her knowledge of students' sociocultural backgrounds and living conditions in the urban setting helped her to identify specific teaching strategies and resources suitable to the students' needs and interests. The study results imply that science instruction can be more feasible in meeting the demands of particular groups of students if teachers make an effort to become knowledgeable about their own teaching context and utilize it in developing their PCK.

  • The purpose of this study is to find the point for improvement through the comparative analysis of the 2007 & 2009 revised science curriculum, and the NGSS of the United States with Bloom's revised taxonomy. The results of the analysis confirmed that the revised curriculum in 2009 compared to the revised curriculum in 2007 has expanded the type of cognitive process and knowledge, which promote a higher level thinking. However, the revised curriculum in 2009 has been biased to the type of specific cognitive process and knowledge in cognitive process dimension and knowledge dimension as compared to the NGSS of the United States. In the revised curriculum in 2009, the type of cognitive process such as 'analyze,' 'evaluate,' 'create,' and the type of knowledge such as 'meta-cognitive knowledge' have been treated inattentively. In addition, through comparative analysis, it was identified that the type of cognitive process and knowledge that were neglected in achievement standards were not dealt with in the learning objective of teachers' guides, either. The revised curriculum should consist of achievement standards in comparison to the previous curriculum to reflect better the goals of science education. Therefore, it is necessary to create an achievement standards including various types of cognitive processes and knowledge by improving the method of statement of achievement standards of science curriculum.

  • Basic research have contributed to technological growth or economic growth in U.S. Specially recent studies say that universities also contribute to economic development through scientific activities like science research, education, technology transfers. But we can not assure whether scientific knowledge was connected to real technology or economic performance, and it is difficult to figure out the effect of scientific output. "What is the exact performance of scientific knowledge?" It is still obscure. In this context, this paper analyzes characteristics of the linkage of science and technology. Data are U.S. R&D expenditure, scientific articles, citation of articles in U.S. patents by fields and sectors. As a result, university sector has the most weight of the linkage of science and technology. But, in relative connection rate analysis, industrial sector's is stronger than any other sectors. In the field analysis, linkage of science and technology is very strong in Chemistry, Physics, Biological sciences fields. And recently the linkage was increased in the fields of Computer science, Agricultural science, Engineering. Finally, this paper supports funding policy or estimation policy of government to product of scientific knowledge. University sector is still important because it has the most weight of the linkage. Scientific knowledge of industrial sector is also important. The connection rate of industrial science is the strongest in all sectors. And this research classify the R&D type by science fields. Considering the differences of science fields is needed to product science knowledge effectively.

  • This study is an examination of knowledge-based society's impact on knowledge, it's functions, and it's types in fields of humanities an social sciences. Knowledge-based society does not invalidate the definitive mechanism underpinning social coexistence today, but the importance of knowledge will increase greatly whereas the importance of the productive resources labor and capital will diminish. Therefore, knowledge-based society demands that we enter at this time into a discussion that takes new approaches to the knowledge. This study provides a doorway to a discussion of topics such as : Anticipating and characterizing the knowledge-based society, spectrum of fields of new types of knowledge for which typical differences can be ascertained, the interlinking of various disciplines in the respective field of knowledge, the new roles and types of knowledge in the fields of humanities and social sciences.

  • This study examined the changes of preservice biology teachers' NOS pedagogical content knowledge through two consecutive science methods courses: NOS understandings; attitudes toward teaching science; difficulties of NOS teaching; NOS teaching strategies; and views of orientation of NOS teaching. During the science methods course I, the preservice teachers engaged in discussions and reflections on what science is and how scientific knowledge has produced, drawing NOS aspects from episodes of history of science, and planning the lessons cooperating NOS instructional objectives. Then the next semester, through the science methods course II, the preservice teachers had a chance of the simulated teaching by adopting NOS teaching and learning activities in the context of the secondary biology context. The preservice teachers, further, reflected on their NOS teaching. The results showed that the preservice teachers constructed the NOS pedagogical content knowledge. They significantly improved their views of NOS and its teaching(p<.05) after the science methods course I, and retained their understanding after the science methods course II(p>.05). The preservice teachers mentioned the difficulties of teaching NOS in the secondary biology context, and further suggested effective NOS teaching methods in their reflective journals.
