In this study, pre-service chemistry teachers' questions in their teaching practices were analyzed considering the context of discourse. Five pre-service teachers participated in the study. Their questions were analyzed by considering various data including class videos, interviews, and teaching-learning materials. Their questions were classified into relevant question, affective question, dead-end question, rhetorical question, and structuring question. Each question was also classified into appropriate question and convenient question by the aspect of proper responses of students. The analyses of the results indicate the differences in the frequencies of several types of questions depending on the content of the lessons. After using convenient questions, pre-service teachers proceeded to prepared classes as they rather than prompted students' responses. The affective questions were rarely used. The dead-end questions were found to be used for promoting interaction with students. The rhetorical questions were used for various purposes such as arousing students' attention or promoting their thinking. Practical implications were discussed based on the results.

This study examined the effects of an online-based learning STEAM program using Metaverse on elementary school students' attitudes toward and satisfaction with STEAM in 197 students in grades 2, 4, and 6 at a rural elementary school. To conduct this study, we developed and implemented a four- to five-lesson online-based STEAM program in each grade level. The conclusions of this study are as follows. The online learning STEAM program had a statistically significant effect on improving elementary school students' attitudes toward STEAM, and students' satisfaction with the program was high. In addition, the pilot teacher said in an interview that 'the students' attention to the program was very high, and it was very interesting to use the Metaverse space'. Based on the results of the pilot, one STEAM program for students and teachers was developed for the fourth and fifth periods of each grade level in elementary school. Online learning programs using Metaverse have the potential to transform education during the pandemic by addressing educational inequalities and providing a flexible learning environment. Therefore, we propose a study on the development of online STEAM programs for middle and high school students.

The purpose of this study is to examine not only students' cognition in the mathematical error-finding activity of the concept of irrational numbers, but also the students' learning stance regarding the use of errors and a teacher's questioning strategies that lead to changes in the level of mathematical discourse. To this end, error-finding individual activities, group activities, and additional interviews were conducted with 133 middle school students, and students' cognition and the teacher's questioning strategies for changes in students' learning stance and levels of mathematical discourse were analyzed. As a result of the study, students' cognition focuses on the symbolic representation of irrational numbers and the representation of decimal numbers, and they recognize the existence of irrational numbers on a number line, but tend to have difficulty expressing a number line using figures. In addition, the importance of the teacher's leading and exploring questioning strategy was observed to promote changes in students' learning stance and levels of mathematical discourse. This study is valuable in that it specified the method of using errors in mathematics teaching and learning and elaborated the teacher's questioning strategies in finding mathematical errors.

The purpose of this study is to find out how those taking early childhood preservice teachers experience their learning through learner-centered education and the meaning given by such experiences to grasp their values. Especially, to look into experiences of learning the project approach theory studied and directly experienced, which is one of the early childhood educational approach methods, data on participatory observation, personal interviews, personal reflective journals, activity reports and ect. were collected and analyzed by the current writer, who fully participated in the class. The meaning of early childhood preservice teacher'experiences in the project approach was analyzed from the two aspects of 'my' learning activities and 'teacher's teaching activities. In the aspect of 'my' learning activities, they got indulged through purposeful practices in the process of tackling problems that originated from personal interest and wanted to share the joy of learning they'd had with others. Aware of themselves as doers of behavior and thinking, they were found to be able to focus an 'my' own learning activities based on these learning experiences of theirs. In the aspect of 'teacher's teaching activities, project theories and practices done at the same time helped them internalize the project and they learned possible changes ign the project by experiencing actual cases. To sum up, the project approach has its meaning in that it not only helps teachers learn theoretical knowledge but also have reflective thinking through their experiences as doers of learning and form practical knowledge. Accordingly, it indicates th need for intensive discussion on the project approach as a way to educate pre-teachers or current ones.

The purpose of this study was to explore the manners in which models are used in secondary science classrooms. A total of thirteen video-recordings of science lessons dealing with the domains of atmospheric and oceanic earth sciences and their verbatim transcripts were analysed both quantitatively and qualitatively. Interviews with three inservice science teachers were also conducted. Six interrelated assertions were generated as the result of the study: 1) The most frequently used models in secondary earth science classrooms include two-dimensional pictorial, symbolic, iconic, and diagrammatic ones; 2) Science teachers employ models as a mode of representation to make the subject matter available to students; 3) In earth science classrooms, teachers use typical forms of models in intensive manners; 4) Students themselves deal with models on a few occasions, but they just follow similar procedures with the same models; 5) Teachers talk rarely about the nature of scientific models and provide few opportunities for students to think about it; and, 6) Teachers in practice think that the value of using models should be appraised in consideration of the pedagogical intentions of the teacher. Implications for science education and science education research were discussed.

The purpose of this study was to explore high school science teachers' perceptions and practices regarding the implementation of achievement standards-based assessment (ASA) in their science teaching. To achieve this, semi-structured individual interviews were conducted with 20 science teachers who had implemented ASA. The participating teachers were asked to share their opinions on ASA implementation, the effects of ASA on changes in their teaching, and students' reactions to ASA. The results were as follows. Most of the teachers recognized that the initial intention behind ASA implementation began to be realized in schools only after course rankings were no longer required to be indicated. Some teachers felt that ASA allowed them to focus on students' progress, rather than evaluating them by achievement scores. It also helped some teachers identify students who were experiencing learning difficulties and offer appropriate support. In addition, some teachers acknowledged being able to reorganize their science lessons according to the essential goals of science subjects in the curriculum and provide more detailed feedback on students' achievements. However, some teachers expressed difficulties in setting an appropriate level of achievement for their lessons or in evaluating students' progress using qualitative methods. Lastly, the teachers expressed concerns about the remarkably lower motivation of some students for learning science after the indication of course ranking was no longer required.

Background : To assess the effects of mDOT implementation on sputum smear conversion for AFB (Acid fast bacilli) positive pulmonary tuberculosis patients, modified Directly Observed Treatment (mDOT) was started on October $8^{th}$ 2001 at a health center in Seoul. mDOT was defined through weekly interviewing and supervising of a patient by a supervisor (doctor, nurse, or lay health worker). The sputum smear conversion of a mDOT group was compared with that of a self-medication (self) group. Methods : This study included 52 AFB positive pulmonary tuberculosis patients registered at a health center in Seoul between October $8^{th}$ 2001 and April $23^{rd}$ 2002. 24 and 28 patients were enrolled in the mDOT and self medication groups, respectively. Paired (1:1) individual matching, by gender, extent of disease, relapse and age-matching variables, was performed between the two groups, resulting in 20 paired matches. This prospective study was planned as an unblinded, non-randomized quasiexperimental pilot project. Outcomes were identified from results of sputum smear examinations for AFB in both groups at 2 weeks, and 1 and 2 months. The paired matching data were analyzed using the SAS program version 8.1 by McNemar test. Results : At the end of 2 weeks of treatment, the sputum smear conversion of the mDOT group was somewhat higher than that of the self medication group (78.57 vs. 50%, p-value=0.289), and after 1 month of treatment no statistically significant difference was shown between the two groups (83.33 vs. 50, p-value=0.125). At the end of 2 months of treatment (initial intensive phase), the sputum smear conversions of the mDOT and self groups were 95 and 75%, respectively (p-value=0.219). Conclusions : The implementation of mDOT did not result in clinically significant increases in the sputum smear conversion at 2 weeks, and 1 and 2 months compared with that of the self medication group. However, the increases experienced might contribute to diminishing the infectious period of AFB positive patients, and this approach may act as a guide for a specific group of patients. In this study, mDOT was performed for one hundred percent of the intensive treatment phase. It can also be an effective treatment for pulmonary tuberculosis patients, and may be useful for some high risk tuberculosis patients.

Transtheoretical model of change has been proven very effective in explaining both the acquisition and cessation of many health related behaviors. The objectives of this study were to describe the distribution of smokers by stage of change of smoking, alcoholic drinking, and exercising in rural residents and to develope health promotion strategies. This study was done in Okchun County of Chungbuk Province. The representative sample were 892 residents over 30 years old. The questionnaires of interview included socio-demographic, the six stage distribution of smoking, alcoholic drinking, and exercising. In male, 50.6% of smokers were in the precontemplation stage, 32.5% in the contemplation. In female, corresponding figures were 60.6% and 28.8%. Precontemplation and contemplation stage of drinker were 72.8%, 19.3% in male and 80.3%, 15.5%. Distribution of exercise were 80.6%, 1.8% in male, 87.6%, 1.2% in female, respectively. The stage distribution of smoker, alcoholic drinker, and exerciser was shift to left of the distribution. And the stage distribution was slightly differ with each health behavior. The stage of change with smoking, drinking and exercising was correlated with each other but not concordant. So interventions in rural residents need to take into account the large proportion of precontemplators repeatedly observed among smoker, drinker, and non-exerciser. And intervention strategies of each risk behavior should be different approach. Result of concordance analysis suggest reconstruct validity of the transtheoretical model in our country due to ethnic and sociocultural difference. This results and theory should be tested in prospective intervention studies for seeking the possible gateway of health behavior.

The purpose of this study is to identify the degree of social presence perceived by students and to explore the factors that have affected it after practicing Christian Education classes as synchronous distance course due to Covid-19. It is also to suggest effective ways in the aspects of the design and operation to improve social presence. In order to measure social presence and derive influencing factors, research related to synchronous distance class and social presence is summarized through literature review. The researchers also surveyed 58 students in three courses of Christian education major at a University in Gyeonggi-do and conducted in-depth interviews with 6 students. The main findings are as follows: First, the sense of social presence was moderate, the emotional bond was the lowest by sub-factor, the open communication, the sense of community was moderate, and the mutual support and concentration were the highest. Second, factors that had a positive impact on the sense of social reality were group activities, selfintroduction activities, active participation in classes, mutual communication such as Q & A or response to peer learners' opinions during lectures by professors, questions, feedback, etc, and having a smaller number of students. Factors that had a negative impact on the perception of social presence were lack of private conversations, poor participation in classes, lack of communication with each other, and difficulty concentrating. The causes of these negative factors were technical problems and limitations arising from zoom, inconvenience and distracting surroundings, lack of time, and psychological awkwardness. Reflecting the results of the study, orientation to effective synchronous distance course, guidance on smooth communication methods, strengthening the role of professors to promote learning, strengthening group activities and learner-centered activities, and proposing a smaller scale of students were ways that are offered to improve the sense of social presence in synchronous distance courses.
