The purpose of this study is to investigate the stress factors experienced by science teachers and stress related to science teaching. To do these, I have developed the Science Teacher Stress Inventory, which consisted of 50 stress factors with subcategories such as student characteristics, teacher characteristics, school environment, administrative procedures, and conditions of service. 104 science teachers have participated in this questionnaire survey. Additionally, I got 109 stress cases related to science teaching from surveys of 25 science teachers. Results are as follows: first, stress from students characteristic and administrative procedures are perceived as having more stress factors than teacher characteristics, school environment, and conditions of service. Second, stress in affective domains such as students' low motivation in science and insincere class attitude is perceived as having more stress factors than stress in cognitive domain. Third, female science teachers are significantly more stressed than male science teachers. Fourth, students' low motivation and low understanding in science learning are the most stressful factors in stress related to science teaching. Fifth, science teachers feel more stress in evaluation such as experiment test and joint-set exam questions.

The purpose of this study is to critically review the skill-based approach to scientific inquiry in science education and to explore the meaning of science practices that are emphasized in recent science education reform movement. An extensive review of relevant literature was carried out, and the results were summarized according to the detailed themes of the study. In the skill-based approach of which Science-A Process Approach (SAPA) is a representative example, science process skills were presented as hierarchically connected with one another, they were believed to be transferable or generalizable, and science learning through discovery was stressed. These points of view are, however, contradicted with those of the modern philosophy of science which suggests the theory-laden nature of using the skills. The skill-based view has also been criticized by the fact that the use of inquiry skills is content-specific or context-dependent and that science theories or principles cannot be discovered by induction. In contrast, the recent view understands science practices holistically, emphasizes the diverse ways of doing the practices which vary with different contents or contexts, and considers student ideas importantly in the science classroom. The findings of this study can contribute to the development of a new science curriculum by providing implications for establishing a consistent view on scientific inquiry.

The purpose of this study is to investigate the effect of science writing heuristic class on 'seasonal change' on elementary school students' science learning motivation and scientific attitude. In order to carry out this study, 49 students from 6 grade of elementary school in P metropolitan city were selected and 24 students in one class were selected as experimental group and 25 students in the other class were selected as the comparative group. The experimental group was taught science writing heuristic in 10 times classes related to the 'seasonal change' and the general classes related to the 'seasonal change' were conducted in the comparative group. Based on the results of this study, the conclusions are as follows. First, the science writing heuristic class about 'seasonal change' showed a significant effect on elementary school students' science learning motivation for science class. This is analyzed as a result of the students being more familiar with their science class through science writing heuristic class. Second, the science writing heuristic class about 'seasonal changes' showed a significant effect on elementary school students' scientific attitude. This is because the science writing heuristic class offered elementary school students an opportunity to combine their experiences in daily life with the contents of the class. Third, students' participation, satisfaction, and interest in the science writing heuristic class applied in this study were high. Therefore, it seems to be effective if the science writing heuristic class is used for science class for elementary school students.

This study aims to investigate tenth graders' understanding of the nature of scientific inquiry (NOSI). A total of 100 public school students participated. A questionnaire of Views about Scientific Inquiry was used to assess their understanding of the NOSI, and data were collected using qualitative research methods such as open-ended questionnaires and, when necessary, semi-structured interviews. By employing a constant comparison method to analyze their responses, five students were consistently categorized as the group with informed views regarding all the eight aspects of the NOSI. The rest of the students showed different levels of understanding regarding each aspect. A large portion of the students represented a group with mixed views about four aspects and informed views about three aspects, whereas naive views about one aspect prevailed among them. The results showed that many students comparatively lacked understanding of the aspect related to the scientists' process of constructing explanations and formulating theories. This study discusses the relationship between its results and the current science curriculum and presents implications for the overall enhancement of students' understanding of the NOSI. Finally, it encourages the acquisition of scientific inquiry ability and makes suggestions to promote further studies.

We should treat carefully the one related to human rights among a large number of decision-making in our daily lives. As it is necessary to obtain physical evidences in the process of criminal investigation for solving a certain crime based on the principle of evidence, it leads to an increase in demand for forensic science and forensic geology. Forensic geology could be regarded as a fusion discipline of geology and forensic investigation and it is principally concerned to the study on the connection of a suspect and a crime scene with soil evidence which could be experimented using geological data and methods. So these results could be used as valuable information in a court. After its academic foundation has been builded since the last 1970s, its research objects have been expanded from soil evidence like rocks, minerals, soils, sediments to sociocultural, political, military and medical objects like ancient relics, mines, corpses. Its role is expanded from the simple finding of a particular location to the examination of archaeological theories and historical facts, the testimony of the cause of environmental pollution and the chronic demonstration of geological distribution of plants and anthropological origination. And these bring this discipline promptly to accept developed geological methodologies and to satisfy various forensic geological needs. Specialized forensic investigation institutes work actively for the R&D activities of forensic geology. In Korea, national institute of scientific investigation works a small part of forensic geological activities in total activities of forensic investigation. In conclusion, we concern to the importance of systematic discussion of building in proper position of forensic geology through its R&D methods, application cases of its performance and etc. based on geological characteristics in our country by a specialized geoscience institute.

An assessment instrument dealing with secondary students' views on the nature of science was developed in this study. The features in aspects of the nature of science are generally accepted as characterizing the scientific enterprise and we have focused on are: 1) the purposes of the scientific enterprise, 2) the nature of scientific enquiry, 3) the nature and status of scientific knowledge, and 4) the nature and functioning of the scientific community. The questionnaire is made of three sections; that is, "Scientific Question", "Experiment", and "Belief". The Scientific Questions probe was designed to examine the ways in which learners mark out science as a particular domain, and particularly the types of questions that they think are open to scientific investigation. The Experiment probe was designed to throw light on the ways in which learners may think about theories and their relationship to evidence in a range of contexts. A related aim concerns the sorts of activities that learners consider to be experiments, and their reasons for this. The Belief probe was designed to see whether students are able to articulate the grounds for their acceptance of a proposition and, if they are, to explore the nature of these grounds. The reliability of the instrument developed in this study was found to be 0.86.

This study investigated science gifted middle school students' philosophical views on scientific knowledge, and the effects of discussing and reading related to the knowledge. Ten eighth-graders in a science gifted class participated in this study. The results can be summarized as follows: 1, At the beginning, the students had one of six positions: (a) relativism (n = 2); (b) falsificationism (n = 2); (c) borderline between relativism and eclecticism (n = 1); (d) borderline between falsificationism and eclecticism (n = 3); (e) borderline among relativism, falsificationism, and eclecticism (n = 1); and (f) borderline inductivism and eclecticism (n = 1). This result indicated that most students had on almost modern philosophical view of scientific knowledge. 2, Some students, who had chosen the item of inductivism in some questions of the instrument at the beginning, maintained their selection despite discussions and readings related to scientific knowledge. The data were examples which indicated the difficulty of changing from a traditional view to a modern view of scientific knowledge.

This study was conducted in order to investigate how a Problem-Based Learning (PBL) program titled(called) 'Designing Safe and Strong Bridge' effects scientifically gifted students' scientific attitude, scientific career orientation and leadership. The participants were 19 scientifically gifted students in the second grade in C high school in Gyeonggi province; they were selected by participation in the tri-level gifted students identification step. Before and after 14 units of the program, the participants were asked to take tests about scientific attitude, scientific career orientation and leadership and to write a review about the PBL program at the end. The major results of this study are as follows. First, participants' scientific attitude was statistically significantly improved after the PBL program (p<.05). In the sub-domain of this area, six parts excluding the part of openness were significantly developed. Second, the degree of scientific career orientation was statistically significantly improved after the PBL program (p<.05). All 4 sub-domains in the degree of scientific career were significantly developed. Third, all of leadership scores were statistically significantly increased after the PBL program (p<.05). In the first factor, the parts of inner and inter personal characteristics were significantly developed. According to their post-program opinions, participants developed in terms of all the secondary factors, such as ability of interpersonal relation, consideration for others and groups, responsibility for the task, confidence and vision, during the process of PBL problem-solving in the small group work.

The purpose of this study is to examine the practice of scientists from the perspective of Ian Hacking's 'creation of phenomena'. Scientific phenomena, according to Hacking, are regular and do not exist in nature without the intervention of scientists or experimental tools. This study tries to derive scientific educational meaning by analyzing the thoughts and episodes of the 'Sontanda (inter-individual variability)' phenomenon experienced by four life scientists. The Sontanda phenomenon is a common term used by scientists to describe phenomena in which findings do not appear consistently even when studies are carried out using the same experimental procedure and materials. The following four educational implications were discovered as a result of the research. First, we confirmed the importance of embodied knowledge, or non-verbal knowledge, which solves issues by making appropriate judgments and reactions at all times, rather than simply becoming accustomed to the experimental method. This argues that propositional knowledge and non-verbal knowledge should be handled equally in order to provide students with a practical scientific inquiry. Second, we tried to reconsider the picture of the experiment. The phenomenon revealed in the interviews of scientists is rare, and it takes a long time to stabilize the phenomenon. On the other hand, the image of school experiments is always positive and consistent, necessitating a shift in perspective. Third, the precise meaning of scientific practice could be confirmed. This study confirms that scientists use their knowledge effectively in line with the circumstances, and we examined strategies to apply scientific practice to school instruction based on this. Finally, by provoking uncertainty, the Sontanda phenomena may give students with an opportunity to engage in meaningful scientific involvement. By breaking away from the cookbook experiment, this study expects school experimental education to help in efforts to experience scientific practice.
