Objectives: Practice of dental technology poses great potential risk since the manufacturing processes are complex and involve dangerous devices and the students are asked to handle various materials in the casting and processing process. Lacking an understanding of the overall practice process, the beginners of practice are exposed to greater danger due to their unsafe attitudes and poor practice attitudes. This study set out to investigate the students of dental technology for their attitudes toward safety and their practice of safe actions during practice and to provide basic data for safety education to prevent any possible safety incidents during practice. Methodology: The subjects include total 408 dental technology majors in their sophomore and junior year. Based on literature study and previous studies, a structured questionnaire was made, distributed to the subjects right after practice, and gathered on the spot. The questionnaire contained total 60 items, and data were collected from April 20 to May 25, 2006. Results: Collected data were analyzed in frequency and $X(C)^{\sim}$-test using the SPSS 12.0 version. The analysis results show that the students believed that they could prevent safety accidents by following safety rules and guidelines as far as safety attitudes were concerned. However, they did nothing more than paying attention to many practice processes even though they thought they were dangerous. Conclusion: Overall the subjects practiced proper safety actions during practice with significance differences in their behavioral characteristics according to grade, gender and age. The significant differences according to grade seem to derive from safety education before practice, and those according to gender and age have more to do with individual actions and common sense according to gender and age than education. Thus practice teachers need to develop safety education materials for each practice process and provide systematic safety education before practice so that the students can practice safety actions.

The purpose of this study was to analyzed child care teachers' health state and a relationship between health promoting lifestyle and job stress of child care teachers. The subjects were 101 child care teachers in Busan. They responded to 'health state open ended question', 'health promoting lifestyle scale', and 'job stress scale'. For the analysis of the data, M(SD), frequencies, t-test, Pearson's correlation were run by using SPSS WIN computer program. The major findings of this study were as follows; First, the most uncomfortable symptoms of child care teacher's physical health state was respiratory organs and the main cause was classroom ventilation and dust. The most uncomfortable symptoms of child care teacher's mental health state was tension and the main cause was children's safety. Second, the mean scores of the variables were as follows : the mean score of health promoting lifestyle was 2.54. The highest sub factor of health promoting lifestyle was 'positive self recognition' and the lowest one was 'exercising'. The mean score of job stress was 2.80 and the highest sub factor was 'administration services'. They desire for a healthy life, but in reality, they are unsatisfied with their current health state and they are not able to practice certain actions actively to promote their health. Third, health promoting lifestyle was negatively correlated with job stress. The result of this study can be used as the basic data for reducing day care teacher's job stress, development of a program to promote day care teacher's health and improving day care teachers working environment.

In this study, we analyzed pre-service teachers' levels of pedagogical reasoning while watching video clips of elementary school students' discussions of their conceptions of solution and dissolution. 81 pre-service teachers participated in the study. It was found that many pre-service teachers had scientific conceptions, and pre-service teachers who had non-scientific conceptions showed misconceptions similar to those of elementary school students. In both conceptions, pre-service teachers partially or comprehensively interpreted the students' misconceptions with reference to the evidence. However, the rates of pre-service teachers who misinterpreted or simply restated the students' utterances were quite high. Many pre-service teachers suggested only one factor related to levels of reasoning about causes of misconceptions, and most suggested factors were related to the student factor. The level of reasoning about instructional decisions differed according to dissolution and solution conceptions. Actions linked to students' thinking were more closely related to students' specific thinking than to their generic thinking, and among these, student-centered action was seen. From the above results, we sought ways of improving pre-service teachers' pedagogical reasoning.

The goal of this study was to find out how prepared Korean high school teachers are to identify suicidal students and connect them to appropriate resources. This study surveyed 390 high school teachers in terms of their level of knowledge on youth suicide and their misconception on suicide. In addition, this study examined what kind of actions they usually take once they identify suicidal students. Results indicated that high school teachers in Korea did not have sufficient knowledge to identify suicidal students and they did not think they are capable of identifying those students. Although their misconception on youth suicide was not as pervasive as expected, some of the misconception were still problematic in relation to suicide intervention. Furthermore, their intervention strategies for suicidal students were quite limited, focusing on isolated individual efforts. It is critical to develop and implement teacher training programs for youth suicide prevention which address suicide risk factors, warning signs, crisis response, and referral procedures.

This study is to identify the concept of action from the critical science perspective and to explore the agency of home economics teachers for the purpose of teacher education. The context and various characteristics of home economics teacher' agency were identified in terms of philosophy and teacher education. The results of the study indicates, first, the concept of action refers to an activity of individuals involving one's own intentions, and include the ability to reveal a unique identity that aims to reach a set purpose and decision, and this can be identified by mutual meaning in the public sphere. Second, teacher agency is influenced by a teacher's professional experiences and cultural and structural aspects, and it can create an environment which can promote self-directed and cooperative relationships among individuals and communities. Therefore, home economics teachers should be able to reasonably judge, contemplate, and act through reflections on the circumstances and consequences in which their agency is exercised. Third, home economics teachers can reflect and think critically about the values, roles, and sense of purpose of home economics education based on agency. Teachers should focus on the process of achieving their agency rather than on completing it, and they can continuously develop it through a perceived shared understanding among teachers. Therefore, the conceptualization of the agency of home economics teachers is to understand the practice revealed in a teacher's actions. This requires environmental support in school settings because it acts as a mechanism for strengthening the thinking and reflection of teachers through the creation of interactive environments in which professional knowledge and experiences can be shared.

This article examines K-8 pre-service teachers' (PSTs) engagement in lesson plan modification using the eight Mathematics Teaching Practices (MTPs) in Principles to Actions, the most recent landmark publication of framework by National Council of Teachers of Mathematics (NCTM) in the U.S. The activity consisted of four phases that involved the analysis and modification of an existing lesson plan. Fifty-seven PSTs participated in the activity throughout the semester, and data from each phase was analyzed using the inductive content analysis approach. PSTs' initial conceptions of lesson planning reflected little on teaching practices (i.e., the MTPs) with more emphasis placed on the form - rather than function - of lesson elements. With the opportunity to interpret MTPs and analyze lesson plans using MTPs as an analytical lens, PSTs demonstrated various interpretations of MTPs, made efforts to incorporate MTPs into lessons, and attended to the interwoven nature of MTPs. This article also shares the challenges, conflicts, and tensions reported by PSTs during their participation of lesson plan modification; as such, the results from this study will inform the research examining the pedagogical (im)possibilities for utilizing MTPs in mathematics teacher training programs.

The purpose of this study is to examine the perceptions of pre-service teachers, which directly affect the concepts and ways of thinking of students who are studying Earth science. This work further seeks to identify pre-service Earth science teachers' Earth science-centered ways of thinking regarding the components and the process of water cycle. The concept sketch method was used to survey 50 pre-service teachers who majored in Earth science education at a National Teachers' University. The survey analyzed the preservice teachers' perceptions of a subordinate concept of Earth systems from the applied components of water cycle, and to code the applied concepts with the components of the water cycle based on a subordinate concept of Earth systems including Hydrosphere, Atmosphere, Geosphere, and Biosphere. The preservice teachers only perceived the components of the water cycle as ones in Hydrosphere and Atmosphere. In Biosphere, many participants lack the knowledge about how the actions of plants and animals, and human beings impact the water cycle. About the process of water cycle, the majority of the participants only perceived evaporation and precipitation as the process of cycling: their understanding about the underground flow of water was more lacking than the surface flow.
