  • 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 identify the producing process for Korean nursing knowledge as applied by Foucault's discourse analytic method. By Foucault's discourse analytic method, the problem is not what is knowledge but what sort of knowledge is made up through specific level of practice. A Korean body of nursing knowledge has been discussed since 1980. At the end of 19th century, missionaries transplanted western nursing knowledge and method to Korea. Western nursing knowledge and methods have been developed continuously with both merits and demerits to Korean society. Recently our world has be come a global community via advances in transportation and correspondence. Although each person is different in skin color and shape. there is a clear line between Oriental people and Western people. Nursing science is only one in our world. but western humanistic nursing practice based on western worldview and human life has limits. It is natural that the Koreans as Oriental people have a systemic nursing science to reveal the specific experiential and concrete body of nursing knowledge rooted in the Korean worldview and human life. Nursing science is to understand human beings, to promote health. to prevent illness. to restore health. to alleviate suffering and to search for principles needed throughout all of human life. In Korea, now is the quickening period to shape a Korean body of nursing knowledge because of a shortage of nursing language in matters of intellectual recognition, and unfamiliar practical nursing field where there is no familiarity in the system of nursing research methodology. In reviewing articles from the Journal of the Nurses' Academic Society on Korean body of nursing knowledge, it was found that there are two common features. The first, human body and mind are inseperable that is one unit in this world and health is keeping a harmonious relationship between human body and mind. The second, Korean nursing practice is based on human nature and family ties. Accordingly discourse analysis has a good future prospect to produce a Korean body of nursing knowledge for analytic research on body and mind monism and family centered care based on human nature and family ties.

  • The purpose of this study was to analyze epistemological beliefs in science as perceived by elementary school students and to examine the purpose of science, the nature of scientific knowledge, the source of scientific knowledge, and the role of experimentation. The subjects of this study were 99 elementary school students. As a tool for examining epistemological beliefs in science, we used adapted questionnaires comprising elements constituting epistemological beliefs, as proposed by Elder (1999). The results of the analysis are as follows: First, in terms of the purpose of science, sixth graders had the most modern beliefs compared to other grades. Second, a statistical significance was found between fourth graders and students in other grades based on the analysis of the nature of scientific knowledge. Third, there was no significant difference in each grade's beliefs concerning the source of scientific knowledge or the role of the experiment.

  • Initial science teacher education in Hong Kong is provided by the Post-graduate Diploma in Education Programme (PGDE) for both pre-service and in-service secondary school teachers. This programme includes a balanced treatment of subject curriculum and teaching in science, general pedagogical knowledge and skills, educational psychology and school administration. The science courses in this programme also have some units that equip science teachers with the knowledge and skills that are essential for teaching a science curriculum that emphasises conceptual change and understanding of the nature and methods of science. This emphasis is illustrated by two studies: (1) Developing a conceptual change model of instruction in Biology teachers, and (2) Constructing understanding of the nature and methods of science.

  • Purpose: The purpose of this qualitative study is to investigate the nature of tacit nursing knowledge practiced in the clinical field in Korea using hybrid models, and to clarify the definitions and attributes of the concept. Methods: The definition and nature of tacit nursing knowledge, obtained through a review of the extensive literature at the theoretical stage of the research, and the analysis of the in-depth interview data conducted by the career nurses in the fieldwork stage, are compared and analyzed. Results: The tacit nursing knowledge was found in three dimensions as knowledge related to the person, the clinical situation work context, the self, the others, and the task. The tacit nursing knowledge was defined as personal nursing knowledge and artistic skills that show up as unconscious behavior patterns, learned informally, and internalizedthrough repeated clinical practice experience based on professional nursing knowledge. Conclusion: Tacit nursing knowledge has been widely used in clinical practice and has been shown to have a great impact, directly or indirectly, on clinical nursing. Therefore, individual and organizational efforts are needed for validation and clarification using the generation, sharing, collection, and peer review of sound implicit nursing knowledge to ensure that it is properly applied.

  • The nature of science has been recognized in a great deal in the field of science education. However, only few innovative programs are offered for science-gifted students to improve their recognition of the nature of science. The current study describes and analyzes science-gifted students' understandings of the nature of science (NOS). In addition, the study looks into contradictory views among the aspects of NOS, which are fundamental data in constructing target programs on NOS for science gifted students. Data used in this study were collected from 73 middle school science-gifted students using an open-ended questionnaire, VNOS. The results of this study showed that the participants' understanding of NOS was significantly distributed on naive or transition view except for 'tentative NOS', and the results revealed inconsistent view among the aspects of NOS. This study proposes two suggestions to enhance the recognition of science-gifted on NOS of science to informed state and to have consistent perspectives with other areas. First, the role of experiment has to be changed-it should be the process in constructing scientific knowledge rather than an instrument to check scientific knowledge to transform perspective on experimental data and scientific knowledge. Second, various opportunities must be provided to science-gifted students, so they can experience the culture and community of scientists and science to gain a wider insight of science.

  • The purpose of this study is to search for the factors that influence students' understanding of the nature of science through the experience of the cognitive processes of authentic open inquiries. The freshmen of a science high school practiced authentic open inquiries reflecting epistemological characteristics of authentic science. The case study was conducted with four focus students who were successful or unsuccessful at learning the nature of science during the authentic open inquiry activity. Questions that the focus students asked during the inquiries as well as students' answers to pre- and post-VNOS (C type) were analysed, and then elaborated in the semi-structured interview. The findings suggest that open inquiry activities provide the inquiry contexts that help science high school students to understand the nature of science, and that the characteristics of students' cognition influence the understanding of the nature of science. For instance, designing experiments with their own research questions had an influence on the students' understanding about the scientific methods and the diversity of research types, and drawing conclusions from their own data made students experience scientific reasoning. In addition, the experience of collecting anomalous data helped students to understand the role of inferences in generating scientific knowledge and the creative nature of scientific knowledge. In this inquiry context, the reflective thinking that came from proactive discussion among students, made students think about the validity of the designing experiments and interpreting data, and helped them to understand the uncertain nature of reasoning and the diverse nature of scientific methods. Moreover, divergent thinking linked to analogical thinking helped students to understand the creative nature of science.

  • The purpose of this study is to explore the variables of knowledge, acceptance of theory of evolution and epistemology that could be keys for teaching and learning the theory of evolution within school contexts, and to suggest instructional tips for teaching evolution in relation to the grade levels of education. This cross-sectional study examined the grade level differences (8th, 11th, and preservice teachers) of four variables: evolutionary knowledge; acceptance of theory of evolution; and both domain-specific epistemology (nature of science in relation to evolution) and context-specific epistemology (scientific epistemological views) and their relationships. This study, then, built conceptual models of each grade level students' acceptance of theory of evolution among the factors of evolutionary knowledge and epistemology (both domain-specific and context-specific). The results showed that the scores of evolutionary knowledge, evolution in relation to NOS, and scientific epistemology increased as the grade levels of education go up(p<.05) except the scores of acceptance of theory of evolution(p>.05). In addition, the 8th graders' and the 11th graders' acceptance of evolutionary theory was most explained by 'evolution in relation to NOS', while the preservice teachers' acceptance of evolutionary theory was most explained by evolutionary knowledge. Interestingly, 'scientific epistemological views' were only included for the 8th graders, while evolutionary knowledge and 'evolution in relation to NOS' (context-specific epistemology) were included in explaining all the level of students' acceptance of evolutionary theory. This study implicated that when teaching and learning of the theory of evolution in school contexts, knowledge, acceptance of evolutionary theory and epistemology could be considered appropriately for the different grade levels of students.

  • As science programs emphasize an understanding of the nature of science, it is needed to assess students' views on a wide range of science-technology-society topics. The purpose of this study is to investigate the views of high school students about some selected topics of the epistemology of science. The selected topics include the meaning of science, scientific assumptions, values in science, conceptual inventions in science, scientific method, consensus making in science, and characteristics of the knowledge produced in science. Identified preconceptions in the study are as follows: Science was seen as improving the world(20%), and technology was defined as the application of science(35%). Almost half of the sample(49%) subscribed to a view consistent with a creationist posture and large group of students(46%) expressed a purely ontological view. Only minority of the students(5%) discounted the role played by private science values, but one half of the sample denied the fact that gender-related values can influence the knowledge that scientist construct(53%). Only a small potion of the sample(5%) held a view contrasting to contemporary epistemology of science, but the majority(67%) expressed a simplistic hierarchical relationship in which hypotheses become theories and theories become laws. One third of the students(33%) held a preconception that the scientific method composed of questioning, hypothesizing, collecting data, and concluding. Students did not appreciate the role of consensus making in science(33%). An out-dated epistemic perspective describes the progress of science as simply an accumulation of knowledge(4%). In general, it was concluded that most high school students did not hold efficient understanding on the nature of science. It can be said that no adequate and consistent instruction took place to provide students with an authentic view of the nature of science.

  • The purpose of this study was to examine preservice secondary science teachers' understanding of the nature of science, by using nature of science (NOS) questionnaire on the basis of atomic model, and compare this to pre-studies. 'Understanding of nature of scientific model,' 'Tentativeness of scientific knowledge,' 'Subjectivity in science,' 'Use of inference and imagination,' 'Myths of the scientific method,' and 'Comparison between science and art.' were examined. Preservice teachers showed great comprehension of the tentativeness of scientific knowledge (the orbital model) and the subjectivity in science (the different interpretation about the experiment of particle scattering), but displayed the lowest comprehension of the scientific method. For understanding of nature of scientific model (the atomic model) and the comparison between science (Bohr's atomic model) and art (Picasso's work), preservice teachers brought out a combination of ontological and constructivist perspective and showed the contradictory thought about imagination in science research. In the result of comparison to pre-studies using the NOS instruments contains general terms, represented high levels of agreement about the tentativeness of scientific knowledge by using concrete examples of 'atomic model'. When concrete scientists such as Thomson, Rutherford, Bohr were presented, respondents revealed more informed views about the scientists' research method.
