  • The purpose of this study was to analyze the interactive patterns between teacher and students in middle school earthh science classroom, identify difference of discourse types between earthh science classes taught by majored and non-majored teacher, find the relationship between the discourse pattern and the type of teachers' questions. For that purpose, the participants in this study included four teachers and their students of three middle schools in Seoul. The data consisted of two parts. First, we categorized interaction between teacher and students into the types of discourses by the use of Mortimer and Scott's analytical framework(2003). Second, we classified teachers' questions into four different types of question based on MNeill & Pimentel's classification scheme(2009) to examine for the relationship between the discourse pattern and the type of teachers' questions. As a result, all teachers used interactive/authoritative discourse most in middle school earth science class. Therefore, there was more authoritative discourse to non-majored teacher in comparison with majored teacher. And study demonstrated that the discourse pattern was more related to feedback about student's response rather than the type of teachers' question. In other words, the dialogic discourse showed up more frequently when the teacher used delayed feedback with positive and accepting attitude.

  • Objectives: The objective of this study was to investigate the prevalence rate and factors related with low back pain(LBP) in senior high school teachers. Methods: Questionnaires were completed by 405 teachers at 13 high school in Andong city in July 2-14, 2001. The information was used to estimate odds ratio(OR) and 95% confidence intervals(CI) for factors relation to LBP prevalence. A cross-section study design was used in this study. Results: The pointprevalence rate for LBP was 26.4%, prevalence rate for 6 months was 36.0%, prevalence rate for 1 year was 36.5%, and experience rate during life time was 55.1%, The factors associated with LBP by Chi-square test were marital status(p=0.014), An angle for back rest of car seat(p=0.014), and vibration of seat (p=0.003), 12.2% for patients with LBP was a higher than 6.0% for without in singles, Patients(29.0%) were higher than no patients(17.8%) in above $100^{\circ}$. 14% for patients who exposed to a high vibration. Vibration significantly associated with point prevalence rate for LBP were marital status and lecture time in logistic analysis. The married teachers had a higher LBP experience than singles(OR=2.6, 95% CI 1.13-6.03). The teachers who have a lot of lecture time in a day had a higher experience than those for less time(OR=1.6, 95% CI 1.42-2.51). Conclusions: Results from this study indicate that a statistical significant factors relation to LBP were marital status and lecture time in a day.

  • This study aims to investigate how pre-service elementary school teachers understand 'something scientific', 'being scientific', 'scientific events' and 'scientific questions' through semantic network analysis. To achieve this purpose, this study carried out a central analysis of the frequency and density of words and the degree of connection between key words, a concentric analysis, a click analysis and a common network analysis through text semantic network analysis by using NetMiner 4.0 Program. Based on the results of these analyses, this study came to the following conclusions. Firstly, in perceiving 'something scientific', pre-service elementary school teachers recognized 'verification', 'objective' and 'experiment' as most important words. In other words, they perceived that main grounds for something scientific should be provided through clear facts, possible to be verified and accompanied by an exact and logical theoretical system. In regard to 'being scientific', they perceived 'explanation', 'objective' and 'verification' as most important words, while having a traditional point of view that science is a set that can be explained objectively. Secondly, in regard that the term, 'observation', is contained in 'scientific events', they showed a high rate of understanding it as a scientific event. In regard to scientifical reasons, they showed the highest frequency of 'observation', and for unscientific reasons, they showed the highest frequency of 'behavior'. In perceiving 'scientific questions', they showed the highest frequency of determining bacteria-related questions as scientific. As a reason why they thought as scientific, they mentioned 'observation' most frequently like 'scientific events', while mentioning 'value judgement' as a reason why they thought as unscientific most frequently. From the results of integrated network analysis, this study found out that words pre-service teachers commonly used in stating scientific events or scientific questions were overlapped with words they mentioned for scientific events or scientific questions. As a result, it was found there were many pre-service teachers having interpreted scientific words without clearly distinguishing scientific events or scientific questions.

  • The purpose of this study is to investigate the perspective of pre-service chemistry teachers on the learning situations of visually impaired students through scientific inquiry in a darkroom and to propose a teaching and learning method for students with visual impairments. Twenty-one pre-service chemistry teachers from college of education in Gyeongbuk were encouraged to explore individually hands-on model for the molecular structure of ice freely, and had a discussion with a one of the researchers during the activity. All the conversation and discussion were audio-taped and transcribed for analysis. As a result, pre-service chemistry teachers realized that learning situation of the visually impaired students was quite different with their perception while exploring and figuring out hands-on model of the molecular structure of ice in the darkroom. They already learned and could see this model by themselves but also recognized that visually impaired students had inconvenience and difficulty in learning science concepts. Based on these reflections, some pre-service chemistry teachers suggested directions for modification to fit visually impaired students' needs more.

  • This study was conducted in order to evaluate the current status of management of students affected by food allergy and provide basic data necessary to school foodservice. A survey was conducted on 300 nutrition teachers (dietitians). For food allergy management, 79.3% of participants regularly checked on students with food allergy. The rate of providing allergy-free or alternative food for students with food allergy was 35.7%; and the reasons for not providing such food was 'lack of cooking time and employees' (69.4%). Furthermore, 79.7% of participants provided nutrition education and counseling for students with food allergy and the reasons for not providing education and counseling was 'lack of time' (59.0%). Nutrition teachers (dietitians) with experience of job training related to food allergy comprised 53.7%. The mean score of importance of food allergy management was 4.02/5.00. The items with high scores of importance of ${\geq}4.20/5.00points$ were periodical check on students with food allergy, sending newsletters or homepage posting of foods causing allergy; however, provision of allergy-free or alternative food scored 3.64/5.00 points. The score of importance was significantly higher in those who checked on students with food allergy (p<0.05), offered allergy-free or alternative food (p<0.01), and in those with experience of job training (p<0.05) than those who did not. Therefore, in order to manage students with food allergy, nutrition teachers (dietitians) require on-going training on food allergy in order to practice provision of alternative foods and administrative support to the cooking personnel and facilities.

  • This study collected data from 467 nursery teachers and it aimed to investigate the association between mental health and emotional dissonance and job burnout of the day care nursery teachers. Measurement tool was developed, most of the questions having 5-point scale. The data were analyzed structural equation model with the statistical package IBM SPSS 23 and AMOS 21 with 5% percent of significance level. Main results are as follows. First, it was found that emotional dissonance of nursery teachers working in day care centers showed significant effect on the mental health such factors as job-stress (relationships with children and parents and work overload). Second, emotional dissonance were found to have a significant effect on job burnout, too. Third, job burnout had a significant effect on the mental health, job stress and psychological wellbeing. Fourth, job burnout was found to mediate partially on mental health and emotional dissonance. These findings suggest the importance of mental health promotion programs for child care teachers working in the day care centers.

  • The movement control order and shutting down educational institution in Saudi Arabia has jeopardized the teaching and learning process. Education was shifted to distance learning in order to avoid any academic loss. In the middle of the Covid-19 crisis, there is a need to assess the full image of e-learning in Saudi Arabia. To investigate student and teachers' perception and acceptance, parents' attitudes and believes about distance education are the main goals of the study. The mix-method research design was employed to collect data. Three surveys were distributed to 100 students and 50 teachers and 50 parents from different educational institutions in Saudi Arabia, while semi-structured interviews were conducted with 10 parents. Random stratified and convenient sampling methods were adopted. Both descriptive and content analysis was conducted using SPSS25.0 and NVIVO software for quantitative and qualitative data accordingly. The findings showed that students are comfortable with remote education and are receiving enough support from schools and instructors but they think online education can't replace conventional face-to-face learning. Moreover, the results showed that teachers are having challenges in preparing online classes because of the development of conducting online classes and the lack of training. However, parents showed negative attitudes regarding the benefits and values of remote education and preferred conventional learning styles in elementary schools. Parents tended to reject and resist distance learning for several reasons: professional knowledge and lack of time to support their young kids in online classes, the shortcomings of e-learning, young children's inadequate self-regulation. Saudi parents are neither trained nor ready to use e-learning. The study provided suggestion and implications for teacher education and policymakers.
