Purpose: The purpose of this study was to evaluate the effects of school safety education for children to increase their safety behavior. Method: The participants were 262 fourth graders enrolled in S elementary school located in Anyang city. The participants were randomly assigned to three groups. For the first experimental group, school safety education was provided for both children and parents. For the second experimental group, safety education was provided only for the children. For the control group, no treatment was given. Result: The first experimental group showed the highest increment on the classroom safety activities score. The first experimental group also had the highest increment on the outside-the-classroom safety activities score. Further, the first experimental group showed the highest increment on the traffic safety activities score. Conclusion: Safety education in the elementary school is very effective to ensure children are protected from school and traffic accidents. Also safety education can be more effective if safety related parent education programs are provided to parents. Therefore safety education should be provided systematically for both children and their parents to prevent childhood accidents.

The purpose of this study is to propose an appropriate criterium for proper sound insulation service preventing school classrooms from aircraft noise. The guideline of noise level for school facility by Korean school health law is less than Leq 55 which is less stringent than that of other countries. It has been reported that many students are annoyed and disturbed for their works when they are exposed to the noise level over Leq 55. It is desirable to modify this guideline of indoor noise level for school classroom. The noise level of classroom of which windows are opened was measured relatively high in case the school is located at the outside of the official area damaged by aircraft noise. In order to minimize the influence of aircraft noise on the school classrooms in the vicinity of domestic airport, it is necessary to improve the present criteria of WECPNL 75 for the establishment of the area damaged by aircraft noise from WECPNL 70.

CPMS(Classroom Power Management System)는 유비쿼터스 센서네트워크 기술을 적용한 층별 강의실 조명 전원을 관리하는 시스템이다. 강의실에는 조도를 센싱하는 모트와 조명 전원을 제어하는 모트가 설치되어 있어, 주기적으로 센서 데이터 및 강의실 전원 상태를 주기적으로 CPMS서버에 보고한다. CPMS 서버는 베이스 모트를 통해 각 강의실의 방의 제어 모트들과 통신하고 전원을 제어하고, 윈도우즈 GUI 소프트웨어를 통해 모트의 상태를 표시하고, 강의실 사용에 대한 스케줄을 입력하여 관리한다. 본 논문에서 CPMS는 모트간의 통신은 IEEE 802.15.4/Zigbee모듈을 사용하여 구현했고 서버소프트웨어는 윈도우즈 시스템을 기반으로 C# 언어와 MS SQL Server로 구현하였다. 본 시스템은 장치들 간의 통신이 모두 무선으로 이루어지므로 설치가 쉽고, 유선 공사에 드는 비용을 절감한 수 있을 뿐 아니라 유선 공사가 난감한 기존 빌딩에서도 구축할 수 있는 장점이 있다.

Background: This study evaluated the learning outcomes of dental hygiene students' ethical consciousness and ethical decision-making competence through dental ethics courses conducted in some universities. Methods: The subjects were 35 and 29 fourth-year dental hygiene students at G University in the first semester of 2021 and 2022, respectively, and 53 and 43 third-year dental hygiene students at D University, respectively, for a total of 160 students. After implementing the dental hygiene ethics course, classroom performance was evaluated in terms of moral sensitivity, confidence in making ethical decisions, classroom practicality, learning outcomes, and class satisfaction. Statistical analysis was conducted using independent t-test and paired t-test, and the statistical significance level was 0.05. Results: Both universities reported an increase in moral sensitivity and confidence in ethical decision-making after the course (p<0.001). Classroom practicality and class satisfaction for the dental hygiene ethics course did not differ between disciplines and were rated positively with a score of 4 or higher (p>0.05). Learning outcomes were higher among 4-year students than 3-year students (p<0.001). Conclusions: It was evaluated that the ethics in dental hygiene curriculum can strengthen students' competence in ethical decision-making, including moral sensitivity and confidence in solving ethical problems in dental hygiene.

The purpose of this study is to investigate the elementary school students' perceptions of scientist and socio-cultural background towards science. Subjects are 120 ordinary students of elementary school and 75 participators in invention club and science camp for talented students in a metropolitan city. A questionnaire for investigating the students' perceptions and Images about scientist was developed. That contains the items for socio-cultural background and experiences towards science. The results of this study showed that the elementary students think scientist is younger than the previous students thought. But as yet, the representative image of scientist is the neat man with glasses and gown. Also, a majority of elementary students like science, science subject and science classroom, especially experiment activity. They have various experiences related in science.

The purpose of this study was to examine the change in the classes of beginning science teachers through the collaborative mentoring program that induce reflective thinking practice. Participants in this study were three mentor-teachers, two teachers in doctor's or master's course, one university professor, and three mentee-teachers who have less than four years of teaching experience. We collected data such as video recordings of the mentee-teachers' classroom teaching and transcription, lesson plans, recording of one-on-one mentoring and transcription, mentor and mentee's journals, and RTOP classroom teaching observation reports. RTOP was used for the analysis of classroom teaching and mentee-teachers' recognition and changes in their classes were found out through journals and one-on-one mentoring interview materials. According to mentee-teachers' recognition and changes in their classes during the mentoring program, they themselves recognized their teacher-centered teaching style, misconception, and lack of content knowledge. Furthermore, there were changes in the mentee-teachers' classroom teaching through their reflective practice and improvement. As a result of this study, the interactions with mentor-teachers through collaborative mentoring program stimulated mentee-teacher's reflections on their teaching. Therefore, these reflections led to their reflective practice that showed progressive changes in their teaching behavioral activities. The extent of these changes varied according to the mentee-teachers' individual disposition toward reflection and the issue of whether mentee-teachers' reflective practice was in accordance with priorities in motivational ZDP or not. Also based on the results of this study, the teachers' reflection was not all accompanied by reflective practice even if the beginning science teachers made some partial changes in reflective practice through reflection. It means that it is hard to lead reflective practice for mentee-teachers through mentoring in a short period of time. Therefore, we consider that a systematic and long-term mentoring program is necessary for beginning science teachers.

The purpose of this study was to investigate the characteristics of formative assessment in elementary school science teaching. In order to examine the practices of formative assessment in science teaching, 8 science classes were observed and video-taped for each of two instructions. We also interviewed the teachers and students with semi-structured questions. The result indicated that the teachers used planned formative assessment and interactive formative assessment. Teachers assessed three aspects of student loaming in science classroom: the student's personal, social and science development. However, the majority assessed in science teaching was science development. Teachers used observation, question and answer, dialogue, reports, and presentation as the formative assessment methods. The process of formative assessment was categorized as to get information, to judge and to give feedback. These three aspects were interrelated and interdependent. The type of question and feedback was influenced on the extent of the interaction between teachers and students.

The purpose of this study was to investigate preservice teachers' understanding of democratic citizenship. This study utilized the democratic citizenship frame to assess 17 participants' comprehension of this concept. The researcher designed a method course where participants in groups analyzed science activities to identify democratic citizenship components. Through the analysis of two science activities-one on energy and the other on climate change-and the development of science panels addressing various global issues, preservice teachers' understanding of democratic citizenship was enhanced. Preservice teachers showed a good understanding of critical thinking, communication and collaboration, and STS (science, technology, and society); and the most enhanced understanding of empathy, which was the least perceived in pre-survey, component of democratic citizenship. The democratic citizenship frame proved to be a valuable tool for teaching and learning this topic, particularly when applied to socioscientific issues in the classroom. More research-based revisions of the science curriculum are necessary, and more systematic practices with reflections are essential in teacher education.

This study is to understand preservice science teachers' previous experience, beliefs about teaching and learning, and visions of themselves as future teachers. The data were collected from two individual interviews with 7 voluntary students and analyzed qualitatively for category construction. As the results of this study, we presented two cases, which showed that their different views of teaching science are strongly related to their previous experiences as learners and observers in schools, and that there is the apparent consistency between each participant's beliefs about science teaching and learning and their own visions of teaching in a science classroom. Implications for preservice science teacher education related to the results were discussed.

The purpose of study was to introduce and propagate the children's verses as the teaching/learning strategies in science education far elementary students and teachers. 238 pre-service teachers, 140 in-service teachers and 602 elementary students wrote the own verses and read colleague's verses with respect to science. In this situation, the writing was considered as creation and the reading was reception and appreciation for the verses. When they wrote the verses, the themes were not restricted except that they were related to science. Mostly, the subjects were something about science concepts, scientific phenomena or experimental instruments, etc. In addition, this study investigated the merits and demerits of the reading/writing activities of children's verses as the teaching/learning strategies in science classroom.
