The purpose of this study is to find out whether pre-service biology teachers' biological meanings of competition and adaptation is the same as everyday meanings to understand natural selection and evolution. Fifty three pre-service biology teachers answered written tests and thirteen of them were interviewed. The tests on general meanings on competition and adaptation, tests on biological meanings on competition and adaptation and tests on natural selection were administered. Questions on semi-structured interviews were composed of only biological meanings about competition and adaptation. Analyzing data through four steps, pre-service biological teachers' general meanings on competition and adaptation were compared with the definitions of Korean dictionary and compared with biological definitions. Pre-service teachers' alternative conceptions about biological competition and adaptation were classified and the alternative conceptual types were checked when explaining natural selection and evolution. They realized competition is battle for intention or purpose like everyday meaning of competition. However, they didn't realize adaptation happen in the population level. They thought that adaptation, like in everyday life meaning, is getting suitable to environment for survival on an individual level. By relating adaptation to evolution, they thought that long-lasting adaptation become evolution. This study has significance with respect to suggesting the alternative concepts of competition and adaptation based on effective evolution teaching from constructivism viewpoint and highlighting the importance of the concepts of biological competition and adaptation, which have been concerned rarely for a long time.

In this study, we investigated the characteristics in the processes of generating analogy for lessons by pre-service science teachers. Eight pre-service teachers at a college of education in Seoul participated in this study. After the workshop of analogy in science education, they generated analogies for lessons. In order to investigate thought processes deeply, we used the think-aloud method and also conducted semi-structured interviews after their activities. Worksheets written by the pre-service teachers were collected. Their activities and interviews were recorded and videotaped. The characteristics in the processes of generating analogy were analyzed in the perspectives of student, analog, and concept. The analyses of the results revealed that they generated analogies to correct students' misconceptions and also considered misconceptions that could be caused by their analogies. They generated analogies using sources with which students are familiar. They also generated concrete and everyday analogies rather than abstract and artificial analogies. There were some cases where they did not clearly grasp the target concepts and expressed the concepts which were not covered in the unit. On the bases of the results, we suggest some educational implications for pre-service science teacher education.

The purpose of this research was to conduct grounded-theory-based explorations on the types of motivation that make pre-service elementary school teachers learn science and on their type-based science-learning processes. One hundred thirty-two pre-service elementary school teachers' motivation types were analyzed, and amongst them, 12 were selected as the subjects to observe their science-learning processes to which grounded theory applied. As a result of analyzing their science-learning motivation types, it was found that the majority belonged to the type "accurators", followed in descending order by the types "directors", "explorers", and "coordinators". Coding various phenomena that appeared in their science-learning processes made it possible to derive 30 categories from them according to the grounded-theory paradigm model elements. Based on such categories derived, analysis could be made on their science-learning process flows by motivation types, according to the grounded-theory paradigm model. For example, the "accurators" were attending science lectures or reading science books to learn science knowledge and how to teach it, from a sense of obligation they took for granted as elementary school teachers. Although their experiences of science-learning processes could not be from pure intentions, due to the teacher certification examination, curriculum, or other environmental factors, they were found to have new perspectives on science with their individual efforts and participations.

This study investigated preservice science teachers' understandings of philosophical foundations(i.e., ontological and epistemological beliefs) underlying constructivist notions of learning. The teacher education program these subjects participated in explicitly addressed philosophical notions consistent with different views of constructivism. For these preservice science teachers, the program provided them with the opportunity to reflect upon the implications that their ontological and epistemological commitments had for their role as a science teacher. Data from four in-depth interviews were used to explore changes in each preservice science teacher's ontological beliefs, epistemological commitments, and pedagogical preferences. Results indicated that ontological beliefs and epistemological commitments were not necessarily consistent with conceptions of science teaching and learning for these preservice teachers. While some students internalized idealist and relativist perspectives, they did not integrate these relativist epistemological views into their preferred instructional practices. Also, regarding the fallible and tentative nature of knowledge, data in this study indicated that participants' epistemological beliefs about scientific Knowledge did influence how they were thinking about their roles as science teachers. Implications for teacher education programs and research on preservice science teacher's philosophical beliefs are discussed.

The purpose of this study is to synthesize the theoretical perspectives, research methods, and research results of teachers' professional vision by reviewing and analyzing previous research papers and to suggest implications for science teacher education and research. Three databases were used to search peer reviewed journal articles published between 1997-2017, which include 'teachers' and 'professional vision' explicitly in abstracts and empirical studies only. 21 articles in total were analyzed and review results are as follows. First, researchers regarded professional vision as a new concept of teacher professionalism. Previous research viewed professional vision as integrated structure of teachers' knowledge or ability activated at specific moment. Second, the analytical framework of professional vision included two aspects; 'selective attention' and 'reasoning'. Several aspects of lessons or the desirable teaching and learning factors are suggested as the subcategories of selective attention. Hierarchical levels or independent reasoning ability factors are suggested as the subcategories of reasoning process. Third, research on teachers' professional vision focused more on middle school teachers than elementary teachers and on various subject areas. Most studies used video clips and more cases of using videos of non-participants were found. In case of measurement of professional vision, most quantitative scoring methods were whether the responses of experts and teachers on video clips were consistent. Last, most studies examined or assessed teachers' professional vision. It is reported that in-service teachers' professional vision was evaluated higher than novice teachers' and using video clips were effective to examine and improve teachers' professional vision.

Doctoral professionals who majored Home Economics Education are relatively rare and recently have been produced in a limited number of institutions. The purpose of this paper was to analyze the Ph.D. Dissertation majored in Home Economics Education by research subjects and methods. Just twenty dissertations published in domestic universities were selected through internet search to be analyzed in this paper. This research showed five research subject areas of the dissertation such as core concepts and perspectives, curriculum, teaching and learning, teachers empowerment, and others. Each subject had three to five references and time difference in publication. The research subject related to concepts and perspectives was more likely to be studied in an early stage, followed by the subject of curriculum. The research subject became to be varied to teaching and learning and teachers empowerment areas. The research methods were associated with the research subject, as expected. Literature analysis was common in the subject on concepts and perspectives, curriculum, and textbook analysis, while survey was in teachers empowerment. Teaching and learning subject used various research methods together. Numerous dissertation with variety of research subjects and methods would be expected to be followed to develop research on Home Economics Education.

The nature of school mathematics has not been asked from the epistemological perspective. In this paper, I compare two dominant perspectives of school mathematics: ethnomathematics and didactical transposition theory. Then, I show that there exist some examples from Old Babylonian (OB) mathematics, which is considered as the oldest school mathematics by the recent contextualized anthropological research, cannot be explained by above two perspectives. From this, I argue that the nature of school mathematics needs to be understand from new perspective and its meaning needs to be extended to include students' and teachers' products emergent from the process of teaching and learning. From my investigation about OB school mathematics, I assume that there exist an intrinsic function of school mathematics: Linking scholarly Mathematics(M) and everyday mathematics(m). Based on my assumption, I suggest the chain of ESMPR(Educational Setting for Mathematics Practice and Readiness) and ESMCE(Educational Setting For Mathematical Creativity and Errors) as a mechanism of the function of school mathematics.

This study aims at analyzing 6 OECD countries' (Australia, New Zealand, Sweden, Norway, England, South Korea) national early childhood care and education curriculum (framework) based on the perspectives of its implementation. Its design and development always focus on how the national early childhood education and care curriculum will be applied in the early childhood settings in a correct and faithful way. As a result, teachers are considered the user or deliverer of the national curriculum rather than the one who interprets it and construct their own curriculum in accordance with their students. Five OECD countries which have achieved an integrated system between early education and care systems, take the constructive view of designing and applying the national curriculum. Accordingly, a national early childhood education and care curriculum within an integrated system should be developed in Korea, in order to accept the constructive view of curriculum development and application.

The purpose of this study is to quantitatively and qualitatively analyze the science journals written by pre-service elementary school teachers, and to categorize the view on the nature of science and the process of their change. For this purpose, 112 science journals written by 13 pre-service elementary school teachers were analyzed. The frequency of each area was analyzed using the research framework of the four areas of the nature of science, and the pattern of change in perspective on the nature of science was inductively derived and classified using the VNOS-C test analysis framework. As a result, The nature of scientific thinking, nature of scientific knowledge, nature of STS, and nature of scientific inquiry were described in relatively similar proportions, but among them, The nature of scientific thinking appeared in the largest percentage, and the nature of scientific inquiry was described in the smallest percentage. The variability of scientific knowledge, the importance of empirical evidence, and the positive and negative effects of science were especially intensively addressed. In addition, the changing aspects of pre-service elementary school teachers' perspectives on the nature of science could be categorized into 'naive view maintenance type', 'informed view maintenance type', 'regression type', 'development type', and 'mixed type'. The element of 'the empirical nature of scientific knowledge' showed various patterns of change depending on the students, and most of the students maintained a informed view on the tentativeness of scientific knowledge for several sessions.

The Knowledge of the Channel (e) is often used as educational materials; it delivers very short but compelling message of strong or interesting timeliness. However, as the media environment changes, expectations and demands for The Knowledge The Knowledge of the Channel (e) is used in school education and what should be improved upon to increase utilization of educational resources. We surveyed 361 elementary, middle and high school teachers and analyzed the frequency of using, approach and learning activities of The Knowledge of the Channel (e) in school education. We also analyzed difficulties in using it in the school and what improvements should be made. Result show that the frequency of using The Knowledge of the Channel (e) in school is highest in elementary schools, followed by middle school, and then high school. Teachers strongly consider curricular relevance when selecting broadcasting contents for education, and among programs of EBS(Educational Broadcasting System), most frequently use The Knowledge of the Channel (e). The The Knowledge of the Channel (e) is mainly used as an incentive for increasing motivation. When examined by elementary school curriculum, this material is highly utilized in subjects with content such as society, morality, and science, or with approaches that require various perspectives. However, it is difficult for teachers to find materials directly related to their classes, and since other media content similar to The Knowledge of the Channel (e) is abundant, the utilization of The Knowledge of the Channel (e) is decreasing. To improve this, The Knowledge of the Channel (e) needs to improve its platform and transformed the type of The Knowledge of the Channel (e) content being provided on social media.
