  • In this study, we investigated the characteristics of curriculum design of pre-service chemistry teachers who participated in educational program for teaching in science museum. Three pre-service chemistry teachers at a college of education in Seoul participated. The educational program was composed of workshop, lesson planning and practice, and critique. After the workshop, we conducted semi-structured interviews based on pre-visit, during-visit, post-visit activities planned by the pre-service teachers. We observed and recorded their teaching practices in Gwacheon National Science Museum and following critique by their classmates. We also conducted final interviews. We used a framework for museum practice to analyze their curriculum design. The analyses of the results revealed that all planned their lessons in accordance with the National Science Curriculum, and considered geographical and psychological aspects in their pre-visit activities. They encouraged students to make joint products through small group activities, and gave students autonomy in choosing exhibits to facilitate spontaneous participation. However, they did not consider continuous aspects of pre-visit, during-visit, and post-visit activities. They did not effectively induce students to engage during-visit activities cognitively. They did not make post-visit activities connect students' experiences in science museum to personal experiences.

  • As the Korean society ages, the number of women who specialize in community health care is expected to increase. Therefore, the purpose of this study is to identify and structure the nature of suffering due to job stress among female community health care professionals, and to provide basic data supporting the performance of female health care professionals. To use Parse's theory of human becoming, nine female health care professionals were selected in the community. After forming the "you and me" relationship, the researcher recorded the participants' distress through honest conversations. It was converted to the structure of human becoming through the extraction-synthesis and discovery interpretation process. Through conceptual interpretation, the structure of the experience was developed. At the results, the female health care professionals were the process of overcoming difficulty due to poor working conditions and conflict in roles between work and family through their skills and communication reinforcements in hopes for change. The stable national welfare policies must be established to sustain jobs with female community health care experts through improved working conditions.

  • The present work deals with subjective assessments to propose the objective parameter related to the subjective attribute of reverberation in the coupled room varied the aperture opening size. A 1/10 scale model was built and used for the measurements and subjective assessments. For the subjective tests, binaural impulse responses(BIRs) were measured using a dummy head and the measured BIRs were convolved with anechoic recorded music for the presentation over the headphones. The results showed that the perceived reverberation was the largest in the aperture opening size 12.5%(1.97% of mail) room surface area)and decreased with increasing the aperture opening size over 25% (3.94% of main room surface area) in the main room coupled with the secondary reverberant room. In the main room coupled with the secondary absorptive room, there was no changes in the perceived reverberation up to the aperture opening size 6.25%(0.99% of main room surface area) and it gradually decreased with increasing the aperture opening site over 12.5%. The objective parameter, T30/T15, showed a very low correlation with the perceived reverberation in the coupled room varied the aperture opening size but showed a high correlation with a new objective parameter, T30/Tbp, proposed by the authors. Because the late part decay energy more rapidly increases with increasing the aperture opening site than the early and middle part decay energy, the LDT/EDT or T3/T1 is a better quantifier to measure double slopes in the coupled room than the T30/T15.

  • The purpose of this study is to examine the effects of small group discussion on elementary students' science writing. In this study, four 6th grade students were chosen from an elementary school in Seoul. Students were involved in eight science writing classes and the contents of a small group discussion and interactions were recorded and observed. Students' science works were collected and analysed based on three domains: scientific thinking, logic and originality. The result of this study showed that the contents of a small group discussion greatly affected the scientific thinking domain. A low-achieving student received lots of help from a high-achieving student. It was easy to improve in the logic domain through the science writing classes. Average students got good grades in an originality domain when the subject was related to their real life. A small group discussion would have an effect on science writing ability positively if the students acquired proper guidance on the procedure and manner of discussion. The science writing lesson would be more effective if the learning group was organized homogeneously in the aspects of intelligence achievement and interpersonal relationships.

  • This study investigated the change of pre-service elementary teachers' professional visions through video-based reflection on science teaching with focus on their attention and pedagogical reasoning about student learning. Specifically, we compared two reflection cycles before and after pre-service elementary teachers went through the collaborative video-based reflection process in a professional learning community. The primary data were collected from eight pre-service elementary teachers and included their science lesson plans, videotaped lessons, video-reflection papers, and transcripts from the interviews. Pre-service elementary teachers' attention was categorized in five aspects: classroom management & control, teacher's instruction, students' thinking & learning, subject knowledge, and assessment. The level of their pedagogical reasoning about student thinking and learning was determined with six levels based on the number of evidence, evidence area, and evidence type. The findings revealed that 1) individual reflection is not enough - collaborative reflection is essential to change their attention toward students learning and thinking 2) pedagogical reasoning levels increase gradually throughout the individual and collaborative video-based reflection processes. The participants not only attributed student learning solely to the characteristics of students but also connected it with their own instruction or science content knowledge and used different types of evidences as they went through two reflection cycles. Implications for using video in the teacher education program were discussed.

  • Science field trip is a comprehensive learning activity in which students can solve problems by themselves, whose importance is emphasized in learning for the gifted. But because not much study has been done yet on this, and convergent activities such as solving too many problems or requesting given answers have generally been done, it has been criticized for not being enough to develop the abilities of gifted Students. Therefore, this study attempted to analyze the activity process of the gifted through field trip to which open inquiry is adapted so that the demands of the gifted can be met, and the abilities of the gifted can be brought out. The study focused on 18 gifted elementary science students at Institute of Science Gifted Education, Cheongju National University of Education, and in the field trip process of the students, analyzed the types of establishment of inquiry problems and inquiry process, and the behavioral characteristics of gifted science students shown during field trip activity through field trip proceedings, transcript contents, poster materials, questionnaires, etc. As a result, more inquiry problems were established after than before inquiry, and the level of inquiry problems was also higher after inquiry. The solution process for inquiry problems of the gifted science students were done in the following order: planning, inquiring, follow-up inquiring and consolidating. But it proceeded to open inquiry process, the next stage being decided according to circumstances. Also, in the inquiry that the students did, diverse factors were revealed such as basic and integrative inquiries, and especially, the students were competent in analyzing the results after transforming and interpreting them. And the analysis of the interaction among the students showed many behavioral traits of talented science students.

  • The purpose of this research was to identify the dimensions of modesty and immodesty in dress and to examine the differences in female college students' perceptions, in various cultures, of modest and immodest clothes. The researchers selected South Korea and the United States for the cross-cultural comparison study because these two countries show distinctive cultural characteristics. This study was conducted through both qualitative and quantitative methods. According to the result of the preliminary study, 47 questions were developed. The 4 Likert type scales used in the questionnaire were written in both English and Korean. Pretests were performed simultaneously in both countries. 174 American and 208 Korean students completed the questionnaire. The data were analyzed using SPSS. According to the results of factor analysis, there were 4 factors identified for the modesty-immodesty concept, including 'Conservativeness', 'Body exposure', 'Social appropriateness', and 'Attracting attention from others'. Students answered that they liked to wear conservative and socially appropriate dress in both cultures and that they did not like to wear clothing which draws a great deal of attention to them. Cultural differences were also identified. Based on the results, American students dressed more conservatively than Korean students, while Korean students preferred to wear revealing dress. American students were more conservative and preferred modest clothing. Also Korean students were more open about their body exposure and had immodest clothing attitudes.

  • With progress of the sound and moving picture recording technology, sound and moving picture have been a tool for evidence and memory on human activities. Accordingly, in archival science the importance of oral history as a record is disseminating and the production of oral record is carried out actively. But for producing oral record in archival institutions, the identity of oral record need to be established more firmly. Archival science is the task which delivers the current appearance of life to future through records. Therefore producing oral record in archival science must have unique characters. And archival science is the task which is building current memory. Therefore the identity of oral more firmly. This article intends to explore the meaning and role of oral record from a perspective of archival science. All these days, the theories and methodologies had been developed focusing on written records mainly in the deep-rooted influence of positivism. But as it is enabled the creation and preservation of records through 'speech', it need to be noted that oral record is the very core of tool for delivering the current society shape and collective memory. Therefore this article will intend to explore the meaning and role of oral record as a part of effort to establish the identity of oral record.

  • The purpose of this study was to compare adults' with intellectual disabilities voice pitch between who have choir experiences and those who do not. Participants were a total of 21 male adults with intellectual disabilities (12 choir group members and 9 non-choir group). Praat test was conducted to compare the characteristics of pitch, produced by the participants while they were singing in their comfortable pitch range. The results showed that the range of melodic contour in the choir group was broader and higher than those of the non choir group. Participants in the choir group produced a lower pitch in the beginning note, and they produced a higher pitch compared to the non-choir group on the highest and lowest note of the song. An analysis on the pitch of the individual note that the participants produced revealed a gap between the expected pitch notes and the actual notes produced while singing. In all syllables of the song, participants in the choir group showed higher accuracy of the pitch production, and significantly more accurate on the perfect fifth and eighth intervals. Regarding to the relative pitch, participants in the choir group produced significantly more accurate notes on perfect fifth, perfect fourth, and perfect eighth intervals. Findings of the study suggest that constant singing experience enable them to have pitch training. It also implies for further studies regarding to singing abilities of adults with intellectual disabilities.
