  • The purpose of this study is to analyze and evaluate the nature, role and development of pedagogical content knowledge in science teaching. Two research questions were considered: 1) What are the nature and the components of the pedagogical content knowledge in science teaching? 2) What is the value of pedagogical content knowledge and are there any routes and paths to developing pedagogical content knowledge for science teachers? In order to answer these questions instead of analyzing empirical data, former research literatures are reviewed. The results indicate that science pedagogical content knowledge is a special amalgam of science content knowledge and science method knowledge in a special context of science teaching that is uniquely the province of teacher based on their own special form of professional understanding. As a part of one's own distinctive bodies of knowledge, science teachers' pedagogical content knowledge is an important basis for professional development and competent teachers. It is knowledge of how to teach specific content in specific contexts, also it depends on each teachers' distinctive knowledge structure. Pedagogical content knowledge for science teaching is composed of five components: orientations toward science teaching, knowledge and beliefs about science curriculum, knowledge and beliefs about students' understanding of specific topics, knowledge and beliefs about assessment for teaching science, knowledge and beliefs about instructional strategies for teaching science. The development of science pedagogical content knowledge does not start until teachers have acquired a deeply principled conceptual knowledge of content, also it is promoted by the constant use of subject matter knowledge in teaching situations.

  • Environmental education is usually taught across the curriculum in most of the countries. This teaching approach has been a challenge for teachers to implement it especially in the Malaysian curriculum context. Thus, science teachers require effectual Pedagogical Content Knowledge of Environmental Education (PCK-EE). The purpose of this study was to explore the influence of teaching option and teaching experience on science teachers' PCK-EE. Five components of PCK-EE were investigated in this study, which were: a) knowledge of curriculum, b) knowledge of content, c) knowledge of student, d) knowledge of teaching strategies, and e) knowledge of evaluation. 347 secondary science teachers from the state of Selangor have participated in this survey study. The questionnaire used had 60 items. The findings revealed teaching option has a significant influence on science teachers' knowledge of content (p=0.000); knowledge of student (p=0.000) and knowledge of teaching strategies (p=0.016). In the case of teaching experience, it was found that there is a low correlation on knowledge of content (r=0.174) and knowledge of evaluation (r=0.170) only. Implication of this study leads to the suggestion in enhancing teachers' service training to improve their PCK-EE and subsequently their ability in teaching environmental education across curriculum.

  • During the last three decades, earth science has been re-conceptualized as an interdisciplinary discipline entitled Earth System Science (ESS), which is based on knowledge of the physical earth system and human impact on the earth. While there is increasing effort to teach earth as a system in K-12 education, teachers' preparedness of to teach earth system is still in its infancy. This article focuses on reviewing the literature of teachers' knowledge of earth systems and of how teachers' knowledge of subject matter affects their teaching practice and pedagogical content knowledge (PCK). First, the study investigated a literature of PCK in general as well as in science teaching. Then this study duscuss what teachers' subject matter knowledge (SMK) is and what it means to be in teaching earth system science. Third, a literature of teachers' knowledge of earth system was reviewed. Finally, a number of suggestions and implications are made as to what teacher education program should do to better prepare future teachers to teach earth systems.

  • The purpose of this research is to investigate characteristics of science content knowledge and pedagogical content knowledge shown in the primary school science classes. Through analysis of classroom teaching, explore the features and differences between primary and secondary school science PCK. Using open-ended interviews with the teachers and group discussions on a regular basis to analyze and compare classes of five primary school teachers, the relationship between CK and PCK. Regardless of the school level the teacher's PCK and professionalism is required with varying focus and emphasis. The features of the primary school teacher's PCK are as follows: Firstly, elementary teach secondary teach content, teachers value pedagogical knowledge (PK) content knowledge (CK). The primary school PCK requires more of understanding of students and teaching methods that to subject areas. PCK be without content knowledge, and the teacher's PCK is subject-specific In addition to the characteristics of PCK in the primary school science teaching, ways to set up professional exchange or collaboration between primary and secondary teachers, and to provide supplementary in-service training focused on content knowledge for primary school teachers.

  • This article advocates for a Mode 3 science policy. Compared to the university research-based Mode 1 knowledge production system and the knowledge application-centric Mode 2 innovation system, Mode 3 can be defined as a system that integrates both Mode 1 and Mode 2-type knowledge production models. In this article, based on the major characteristics of the Mode 3 scientific knowledge production system, I agree with the advocates of Mode 3 that constructing a knowledge society requires an inclusive form of knowledge production and innovation system through the democratization of knowledge production as well as the promotion of social values. Moreover, the mechanisms for creating accountable innovation in the Mode 3 system should be given more attention from the science research and policy communities to make public policy for scientific and technological innovation more reflective of social changes. Similar to the ways that the Mode 1 and Mode 2 scientific knowledge production approaches have influenced the development of science policy models, the Mode 3 scientific knowledge production approach, or Mode 3 science, also has the potential to shape a new science policy model. I will refer to this as Mode 3 science policy. In an effort to conceptualize the democracy- and society-centric Mode 3 science policy model, I will articulate science policy strategies in four science policy domains in South Korea from the context of the Mode 3 science approach. These include (1) evaluation of publicly-funded research activities, (2) valorization of scientific knowledge (that is, enhancement of the value of scientific knowledge through governmental action), (3) development of a science policy decision-making support system, and (4) anticipatory foresight of science, technology and society. When adopting and implementing a Mode 3 science framework, one progressive change is to increase socially desirable innovation such as responsible innovation.

  • This paper is an exploratory study to analyze the flow of knowledge in science and technology in order to predict technology innovation. Here, we need to look into the characteristics of how knowledge is created in science, technology and industry to start with. Based on the characteristics we find, we have to understand the relationships between science, technology and industry, and construct a model to link them to each other for future empirical studies. In this study, we take a general view of the existing study results and theoretical models on the characteristics and linkage of scientific and technological knowledge. Moreover, we examine the preliminary framework to link science to technology to industry for further study on the knowledge flow of science and technology. Finally, we present the direction for future study by using the examined models and framework.

  • Due to the oil business, settlements in the Gulf Region developed into prosperous cities. But in the near future, oil is off. The plans of the Gulf Cooperation Council (GCC) states bank on diversified and knowledge-intensive economies. Are those development plans realistic? What is the state of the art of knowledge institutions in the GCC countries? Applying the theoretical frameworks of Knowledge City and Science Indicators research, we empirically and theoretically studied the emerging Gulf cities Kuwait City (Kuwait), Manama (Bahrain), Doha (Qatar), Abu Dhabi, Dubai, Sharjah (all UAE), and Muscat (Oman). Our methodological framework includes grounded theory, ethnographic field study, ServQual-like quantitative questionnaires and semi-standardized qualitative interviews conducted on-site with informed people, informetrics, and, finally, the use of official statistics. In particular, we describe and analyze the cities' knowledge infrastructures, their academics, and expenditure on R&D as input indicators; and publications as well as graduates as output indicators. A further crucial aspect of a knowledge society is the transition of graduates into knowledge-intensive public services and private companies.

  • This study investigated the level of academic passion for elementary school teachers' science pedagogical content knowledge (PCK) and examined the factors that influence the passion. To this end, 161 elementary school teachers in Seoul were selected, and academic passion tests were then administered to evaluate their academic passion for science subject matter knowledge and science pedagogical knowledge. Individual in-depth interviews were also conducted with some of the participating teachers. The results revealed that 'importance' and 'harmonious passion' for learning science subject matter knowledge and science pedagogical knowledge were found at a high level. However, 'time/energy investment' and 'obsessive passion' for learning the knowledge were slightly higher or lower than normal. The 'like' for learning science subject matter knowledge was relatively high, but the 'like' for learning science pedagogical knowledge was slightly higher than normal. The differences in academic passion for science subject matter knowledge and science pedagogical knowledge were greater according to advanced major at undergraduate than teaching career. The teachers evenly selected some factors that influenced their academic passion for science subject matter knowledge and science pedagogical knowledge. These identified characteristics included 'individual interest', 'high school track', 'experience in advanced major at undergraduate', 'experience in science-related graduate school', 'experience teaching science in elementary school', 'experience teaching science at the gifted education institute', 'experience in charge of science subject teacher', 'experience in science-related teacher training', 'experience in developing science-related teaching and learning materials', 'experience in charge of science or science-gifted related work', and 'experience in a science-related teacher community'. However, a slight difference was noted in the selection ratio depending on advanced major at undergraduate. Based on these results, the practical implications for improving their academic passion for science PCK are suggested.

  • This study aims to analyze the relationship between scientific content knowledge of science-gifted elementary students and their expression of scientific creativity, and the characteristics of divided groups according to the levels of their scientific content knowledge and scientific creativity. A science-gifted program was implemented to 33 forth-graders in the Science-Gifted Education Center of an education office in Seoul, Korea. The method of evaluating scientific knowledge was divided into well-structured paper-pencil test (asking specific and limited range of content knowledge of plants) and ill-structured descriptive test (stating all the knowledge they know about plants) to find out which methods were more related to scientific creativity. In addition, in order to find out the characteristics of each group according to the level of scientific content knowledge and scientific creativity, students were required to answer a questionnaire about their own self-perception of scientific knowledge and scientific creativity and how to obtain scientific knowledge. The main results of this study are as follows. First, Both well-structured paper-pencil test (r=.38) and ill-structured descriptive test (r=.51) results of elementary science gifted students were significantly correlated with scientific creativity. Second, As a result of the regression analysis on scientific creativity of science-gifted elementary students, both the knowledge measured by the two evaluation methods have the ability to explain scientific creativity. Third, the students were categorized into four groups according to the levels of their scientific content knowledge and their expression of scientific creativity, and the result showed that the higher the knowledge of science, the higher the scientific creativity. Fourth, the description about self-perception of scientific knowledge revealed that the highest percentage of Type LL students of all 13 students (53.8%, 7 students) answered 'I have little knowledge of plants because I have little interest in them.' Fifth, the description about self-perception of scientific knowledge revealed that the highest percentage of Type HH students of all 15 students (40%, 6 students) answered 'I think my science creativity is high through my experience of scientific creativity. Sixth, the responses to the Questionnaire revealed that 'reading' was the most popular way to obtain scientific knowledge, with 27 out of total 33 students choosing it. In particular, all 18 students from Type HH (high scientific knowledge and high scientific creativity) and Type HL (high scientific knowledge and low scientific creativity) - those with high scientific knowledge - gave that response. On the basis of this research, we should explore practical teaching methods and environment for gifted students to improve their scientific creativity by revealing the nature of the factors that affect scientific creativity and analyzing relationship between knowledge and scientific creativity.

  • Knowledge and technology resources are the most crucial sources for the achievement of sustainable development in competitive advantage. Meanwhile, few empirical studies have clarified the types of knowledge and technology resources that nonprofit organizations (NPOs) use and develop. This study aims to categorize knowledge and technology resources in NPOs that both researchers and practitioners can use to develop the nonprofit sector further. A qualitative research method was used for the study. Data were collected from 31 interviews with senior and founding members of NPOs in Thailand. Analysis of qualitative data identified five critical categories of knowledge resources: human resources, organizational practices, partnership or stakeholder involvement, operational practices, and other resources. This study also illustrates both internal and external technology resources, which are used in sample organizations. The study's findings contribute to developing a body of knowledge management literature related to the knowledge and technology resources of NPOs.
