As a case study on the changes of beginning science-gifted education teachers' teaching professionalism through coteaching, this study deeply investigated the change processes in the aspects of pedagogical content knowledge. We selected two beginning teachers whose teaching careers in secondary science-gifted education were less than five years. The teachers planned, performed, and reflected together their science instructions for secondary science-gifted students during nine class hours over three times. We observed coteaching of science instructions of the teachers, and analyzed the taped videos, the materials, the transcripts for discussions between them and in-depth interviews with them, their reflective journals, and researcher's field notes by using the constant comparative method. This study revealed that the coteaching positively changed the two teachers' practical knowledge about the curriculum for science-gifted education, the instructional strategies for science-gifted education, the assessment in science-gifted education, the science-gifted students, and the science contents although there were some limitations. The results suggest that the coteaching will be useful in improving beginning teachers' teaching professionalism, and provide practical implications in finding the ways to use it effectively in science-gifted education.

Nurturing students' scientific creativity is considered an important element in science education in Korea. The study aims to explore patterns displayed by well-known scientists in their quest for problem finding. Each case of scientists' course of problem solving is described in terms of historical background, a process of problem finding, and a process of problem solving. There are five patterns from ten scientists which are as follows: Pattern 1 is that scientists find problems from insufficiencies and/or errors from explanation of theories at the time and the related cases are A. Lavoisier, G. Mendel, and J. Watson. Pattern 2 shows that scientists find a problem because of strange phenomena unexplained by theories at the time, and here important case studies are E. Rutherford and W. R$\ddot{o}$ntgen. Pattern 3 demonstrates that scientists find a problem from analogical reasoning between known theories and unknown science phenomena. The cases include S. Carnot and T. Young. Pattern 4 points to the fact that scientists find a problem while they utilize a newly invented experimental instrument. Here, G. Galilei is an important example. Pattern 5 establishes that scientists happen to find a problem while they conduct research projects. The works of M. Faraday and J. Kepler are prominent case studies related to this pattern.

This study explored the effects of pre-service elementary teachers' inquiries into science class dilemmas. By closely examining the characteristics of the pre-service teachers' inquiry processes and changes in their educational decisions, the effectiveness of using dilemmas as part of teacher education was determined. Twenty fourth-year university pre-service teachers participated and conducted inquiries into science class dilemmas over seven weeks. Based on pre- and post-questionnaires, KWHL tables, inquiry reports, discussions, and group class presentations, the major factors that influence the pre-service teacher's decision-making changes were extracted. The pre-service teachers found the science inquiry process meaningful when exploring the science topics covered in the dilemmas, and claimed that elementary school students would be able to engage in meaningful science explorations if they learned science through inquiry. Furthermore, the pre-service teachers explored the thinking processes and background knowledge of the students in different ways. Documents such as teacher's guides and the curriculum were examined and the students' thought processes were identified through interviews with the teachers and students, which were found to reflect their educational decision-making. Moreover, it was recognized by the pre-service teachers that depending on the situation, alternative teaching methods were possible. The focus on the unstructured dilemma problems provided the pre-service teachers with problem-solving situations that triggered scientific inquiry and exploration of student thinking and revealed the complexity of science teaching and learning. Based on these results, the teacher education implications for using dilemma cases are discussed.

To investigate the trends in science education research related to play and derive implications for elementary science education research, we analyzed 109 research articles on play in science education published both in Korea and abroad. First, the number of research studies conducted abroad has been steadily increasing since 2009, with the highest number targeting middle school students. Conversely, domestic research has the highest number of papers targeting elementary school students. Second, in terms of research methods, quantitative methods were the most commonly used. Third, the use of questionnaires was the most frequently published research method, while the use of observation and products was smaller in number in domestic studies compared to those conducted abroad. Fourth, In the aspects of the contents, more research was conducted in the field of physics than in other areas. In case of researches for elementary school students, domestic research was focused on four areas of science. Fifth, among the studies exploring effectiveness, the 'cognitive domain' was the most studied, followed by the 'science-related attitude domain' and the 'inquiry and practice domain'. Sixth, the use of play was high in the following order: online games, video games, virtual play, and games with rules. For domestic researches, studies on analog play were most frequently reported, and the ratio of digital games in abroad was higher than that of others. Seventh, the highest number of papers used teacher-directed play, and this tendency was more noticeable in domestic studies.

The purpose of this study is to understand the context of cosumers' lives in Korea with a narrative analysis method. The epistemological orientation of eh narrative analysis is Interpretivism, which blends the two polar philosophical perspectives, Empiricism and Rationalism, and includes Narrotology, Hermeneneutics, Semiotics, and Structural Criticism. Narrative analysis takes as its object of investigation the story itself. This study collects eleven narrative plots from four housewives, into which Labov's structural approach is applied. This study shows clearly that the socio-cultural environment in which consumers live has strong influence on their consumption behavior and also reveals that narrativization tells not only about past actions but how individuals understand those actions, that is, meaning.

The purpose of this study was to examine the curriculum components affecting the professionalism of dental hygienists and to explore what improvements should be done for each of the influential curriculum components to boost the belief and attitude of dental hygienists. The subjects in this study were 934 dental hygiene students, 76 dental hygiene professors, and 285 dental hygienists, on whom a survey was conducted in person, by mail and by e-mail from April 10 to June 12, 2009. The collected data from 1,295 respondents were analyzed. First, overall dental hygiene professionalism was predicted by intellectual development, vocational education, socio-culturalization, ethics and creativity, which were educational objectives of curriculum, and that didn't have a close relationship to interpersonal understanding and selfactualization. Second, overall dental hygienist professionalism was predicted by learning interest, learning possibility and the significance of subjects, which were selection criteria of teaching content, and that wasn't closely linked to the validity of subjects and social significance. Third, overall dental hygienist professionalism was predicted by continuity and integrity, which were organizing principles of teaching content, and that didn't have a strong relationship to sequence. Fourth, overall dental hygienist professionalism was predicted by the content of school evaluation and school evaluation criteria, which were evaluation elements of curriculum, and that wasn't closely linked to the method of school evaluation, the content of the national exam, the criteria of the national exam and the method of the national exam.

This study is to make suggestion for developing textbook systematically by analyzing biological contents and organization in science textbooks which are important instructional media to accomplish objectives of the 6th middle school science curriculum. The inclusiveness degree of the 6th science educational objectives reflected in the textbooks was analyzed by Klopfer's and the Korean Educational Department's objectives taxonomy. And the biological contents and the organization of the science textbook were analyzed by learner, subject matter, and society dimensions which are selecting criteria for curriculum objectives suggested in Tyler's curriculum model. The analyzed results are as follows: 1. The inclusiveness degree of the educational objectives was very low. 2. Regarding the dimension of learner, the concepts of formal operational cognitive level were much increased as grade becomes higher. And the degree of learner's interests reflected on the learning topics and domains was very low. 3. Regarding the dimension of subject matter, the concept-centered learning was increased, in relation to inquiry learning as grade becomes higher. The analyzed results of inquiry subskills showed that observation, classification, and recording skills in 1st grade, observation and operation skills in 2nd grade, and interpreting data skills in 3rd grade were centered. As the problems and processes were presented, so most of inquiry activities had low openness scale. The learning contexts were organized into discipline-centered in relation to real life. 4. Regarding society dimension, the learning topics of environments and health were much presented. but those of biotechnology and career were presented scarcely. And most learning topics related society dimension were organized in textbooks of the 2nd and 3rd grade. These suggested that to accomplish curriculum objectives effectively. the inclusiveness degree of educational objectives is to increase and, the contents and organization of textbook were constructed harmoniously in aspects of learner, subject matter and society dimensions.

This study developed and applied the teacher education model and its principles for science classes using Virtual and Augmented Reality (VR/AR) content and analyzed preservice elementary teachers' feedback on the teacher education model and the changes in their perceptions as to the use of VR/AR content. First, existing Technological Pedagogical Content Knowledge (TPACK) teacher education models and prior studies on the use of the VR/AR contents were reviewed to derive the teacher education model to cultivate the VR/AR-TPACK and set the key principles for each of its stages. The developed teacher education model has five stages: exploration, mapping, collaborative design, practice, and reflection. Second, to examine the appropriateness of the model's five stages and principles, we applied it within the regular course of instruction at the university of education, which was attended by 25 preservice elementary teachers. This study collected data from surveys on the perception of the usage of VR/AR contents before and after the course, as well as the group lesson plans prepared by the preservice teachers, and their feedback on the teacher education model. The feedback on the teacher education model and the survey conducted by the preservice teachers before and after the course were analyzed through open coding and categorization. As a result, most preservice teachers expressed positive opinions about the activities and experiences at each stage of the implementation of the teacher education model. Perceptions related to the usage of the VR/AR content changed in three aspects: first, the vague positive perception of the VR/AR content has changed to a positive perception based on specific educational affordance. Second, they recognized the need for preparedness by anticipating potential problems associated with the use of the VR/AR content. Third, they came to view the VR/AR contents as a useful instructional resource that the teachers could use. Based on these results, we discussed the implications for the VR/AR-TPACK teacher education model and assessed the limitations of the research.

In 1969, Y.J. Yun wrote the terrestrial navigation text book that discussed earth sciences, aides to navigation, chart and publications, tide and tidal current, piloting, rhumb-line sailing, great circle sailing grounded on the hand-on background and theory. It has still been used as a principle text book in a lot of maritime academies and schools. And many contents and definitions came from other terrestrial navigation books published in the United States of America, the United Kingdom, and Japan. But some of them have caused the misunderstanding because they had no enough explanation and explained by incorrect items. In this study, we have found out the problems in the terms course and heading which are related with the direction of the vessel movement, and proposed the amended definitions in order to prevent the misunderstanding and confusion. of them.
