  • The purpose of this study was to investigate how prospective elementary school teachers perceived teacher's inquiryoriented teaching practice, with an emphasis on students' scientific explanations based on scientific evidence. For this study, 94 prospective elementary school teachers were participated. 14 among 94 participants had chances to intensively experience this particular teaching methods for 15 weeks. All of the 94 participants observed the intended science teaching practice for 4th graders in two different elementary schools, which utilized the science talks emphasizing students' scientific explanation activity. For quantitative data analysis, they were asked to provide their reaction to the science teaching methods after their classroom observation. For qualitative data analysis, 5 among the participants, who had relatively long term experience with this teaching practice, were chosen to interview in order to understand their individual reasons of the ways they perceived about the inquiry-oriented teaching methods boosting students' scientific explanation. The results show that the prospective elementary teachers generally thought the emphasis of students' scientific explanation based on scientific evidence could enhance young elementary students' science content understanding, stimulate their curiosity/interests, and further develop their ability to engage actively in scientific discussions. However, some prospective teachers tended to think that the science teaching. methods would not be effective in terms of managing science classes, though. This study concludes that the prospective teachers tended to hold an endemic dilemma. On the one hand, they had their clear preference to the inquiry-oriented teaching practice as the most ideal teaching methods. On the other hand, they also had their persistent hesitance in using these methods due to their fear that elementary students might not adequately grasp the important science content when engaged in scientific discourse through an inquiry-oriented class.

  • This study explored a possibility of science concept learning in scientific practice-based science instruction through the review of literature about situated learning theories and practice-based science education. It was revealed that the situated learning theories were closely related to the recent trend in science education which emphasizes students' active engagement in scientific practices. From the perspective of situated learning, concept learning occurs in the process in which learners make use of concepts as resources and further develop the concepts through the emergence of conceptual agency during their participation in practices. The study also found that the situated learning perspectives could apply to science concept learning in scientific practice-based instruction: Science concepts are used as resources in practice-based science learning, students can better engage in scientific practices as they take advantage of science concepts as resources, and the emergence of conceptual agency can facilitate science concept learning during the participation in scientific practices. Implications for school science education were suggested.

  • In this study, after applying the argument structure class design program for 20 preservice earth science teachers, we conducted individual in-depth interviews, analyzed the data, and derived a scientific argumentation PCK development model. The scientific argumentation PCK development model consists of three dimensions: Scientific argumentation PCK, PCK ecosystem, and reflective practice. Scientific argumentation PCK is demonstrated in the process of designing or executing classes using argumentation structures as an instructional reasoning tool. PCK ecosystem, consisting of the existing conventional PCK components, is a dimension surrounding the scientific argumentation PCK, and these two dimensions develop by interacting with each other. Reflective practice regulates each dimension and develops it in various ways by mediating the two dimensions of the scientific argumentation PCK and the PCK ecosystem. The conclusions drawn based on the results are as follows: First, preservice science teachers can demonstrate scientific argumentation PCK in the process of design and implementation of lessons using argumentation structures as a pedagogical reasoning tool. Second, it is necessary to develop the PCK for pedagogical reasoning tools such as scientific argumentation PCK in advance for the development of science teachers' PCK, since the scientific argumentation PCK can develop various components of the PCK ecosystem. Finally, it is necessary to use scientific argumentation PCK to support the preservice teacher's reflective practice, seeing that the scientific argumentation PCK promotes the development of PCK ecosystem components by inducing reflective practice.

  • Scientists planning research that involves the use of animals are required to examine the possibilities for replacement, reduction, or refinement (the Three Rs), and their protocol must be reviewed by the Institutional Animal Care and Use Committee. Good scientific practice involving appropriate search techniques on the available Three Rs resources is essential for both ethical and scientific reasons. Appropriate experimental design and statistical analysis techniques are particularly necessary for research involving the use of animals, because this can improve animal welfare and scientific outcomes, as well as saving animal lives. There are a number of resources to help researchers improve their search techniques, experimental design strategies, and their reporting of research involving the use of animals. However, there is little specific information or resources on the Three Rs alternatives that is readily available in the Korean language. This paper outlines the common errors made by submitting researchers that have been repeatedly observed during the ethical review of experimental protocols over the last ten years, and provides information on the Korean resources available to promote good scientific practice. This could help to bridge the gap between Korean scientists and animal welfare advocates assisting scientists to improve ethical considerations and conduct responsible research.

Analysis of inquiry activities in the life science chapters of middle school 'science' textbooks: Focusing on Science Process Skills and 8 Scientific Practices (중학교 과학교과서 생명과학 단원의 탐구 활동 분석: 과학탐구 기능과 8가지 과학 실천을 중심으로)

  • In this study, we analyzed activities in life science chapters of middle school 'science' textbooks for the 2009 revised Korea national curriculum and examined the difference between the analysis based on scientific practices and the analysis based on inquiry skills. As a results, there was a lot of inquiry skills in the order of 'reasoning', 'observing', 'classification' in the all of grade. In scientific practices, 'data analysis and interpretation' and 'constructing explanations and devising problem solving' were biased. This shows that life science inquiry activities in middle school 'science' textbooks are lacking in diversity in scientific practice elements as well as inquiry skills, and that the goals of the activities are limited. In addition, through the interrelationships between scientific inquiry skills and scientific practice elements, we examined contents relevance in the transition from inquiry function center to scientific practice, and compared with the results of inquiry activities in textbook, The results of this study were matched monotonously due to the tendency to basic inquiry-data interpretation / basic inquiry-explanation. This comes from results of the lack of diversity in activities presented in middle school 'science' textbooks. In this study, it is suggested that efforts should be made to include diverse scientific practice elements in the process of realizing 2015 revised Korea national curriculum from the simple and diversity-less inquiry activity through analyzing the textbooks of the 2009 revised Korea national curriculum.

  • 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.

  • This study aims to identify what kind of epistemological resources were activated in unproductive and productive practice by students participating in scientific argumentation, and to explore which contexts result in changes in argumentative practice. We collected transcriptions of participants' argumentative lessons and interview, participants' work sheets, and researchers' field notes. The analysis revealed that the focus group activated different kinds of epistemological resources depending on their practice; propagated, belief, and accumulation in unproductive practice and constructed, understanding, accumulation, formation and rebuttal in productive practice. We found two contextual cues that led to these changes; unfamiliar form of argumentative task was provided and emotional, epistemic, and conceptual support of the epistemic authority. This work can be provided as additional case studies to analyze changes in practice according to learner context-dependent epistemology, and we expect to contribute to discussions of productive epistemology and stabilization for students' authentic science engagement.

Science High School Students' Shift in Scientific Practice and Perception Through the R&E Participation: on the Perspective of Legitimate Peripheral Participation in the Community of Practice (과학고등학교 학생들이 R&E 참여 과정에서 드러내는 과학적 실행 및 인식 변화 -실행공동체 내에서의 합법적 주변 참여의 관점에서-)

  • Learning at the elbow of scientist is a well-known educational approach to improve students' understanding of science and scientific practice. This study, in the perspective of legitimate peripheral participation in a community of practice, explores how students' scientific practice and perception could be shifted through R&E program with the development of participation. Data from participant observation for 18 months and in-depth interviews were analyzed based on constant comparative method to extract common characteristics of students' participation and major shifts in their scientific practices and perceptions. Students' development of participation was categorized into three stages: legitimate, peripheral, and full participation. In the stage of peripheral participation, students perceived themselves as mere students and showed passive engagement. They just followed the directions of researchers and didn't know what they should be doing. But through continuous participation, students showed enhanced engagement like voluntary article reading, role assignments, and establishing norms in a community of practice with the reference of scientists'. In this stage of transitional participation, students also showed a deepened perception on everyday life of scientist and the community of scientist. And finally in the stage of full participation, students showed responsibility and ownership on research and continuous efforts to refine their research. They recognized themselves as beginning scientists. With these findings, this paper highlighted the dynamic processes of students' development of scientific practices and identity through R&E participation. It also suggests implications for research programs for education, especially for students who have already articulated a science-related career but still have only foggy notions about science.

  • This study investigated the relation between social worker's beliefs on the nature of scientific knowledge which has been classified objectivism and constructivism and social work practice. As an epistemological position, constructivism is based on a view of knowledge that differs from that of objectivism, which holds that knowledge exists "out there" as objective truth. The focus of this paper is a examination on epistemological beliefs of social worker and social work practice. This paper proves that social work's epistemological beliefs have an effect on the practice modes. This research indicates that social works have a higher constructivist veiws than objectivist veiws on the nature of scientific knowledge. And social worker who have a high level of objectivism show a positive determinative mode. It has suggested that the constructive theory offers useful epistemology to the social worker who should deal with the clients in uncertain situations. In conclusion, a social worker with a high level of constructivism use an approach that creats a more equitable relationship between social worker and client. This perspective will allows cliens to participate in the formulation of theories in practice.
