This study explored the relationship between argumentation and the conceptual change model in a science teacher's explanations. Ten audiotape recordings (about 9 hours) collected in a high school physics classroom were all transcribed. The transcripts were analyzed using the components of Toulmin's argument framework and two constructs of the conceptual change model: the status of a conception, and the conceptual ecology. This analysis reveals that there are dynamic relationships among Toulmin's argument components, the status of a conception, and the conceptual ecology. The episode extracted from the transcripts shows the science teacher's explanations in the flow of classroom discourse, as directed and guided by her, presenting the intelligibility or plausibility of a conception by using warrants or backings such as examples or anomalies, two components of conceptual ecology.

This study aims at re-considering an exemplary teacher in Confucian scholar tradition at the present time of education where teacher's authority gathers dust, the relationship between a teacher and a student is getting hard-hearted and the discussion on the role of a teacher and expertise does not reach an agreement. For this, the article discussed it by dividing an exemplary teacher into a conception of authority, benevolence and example. In view from a Confucian scholar's standpoint, this article found that teacher's authority is rational authority, and it is a product of social institution and social role of a teacher. Moreover, more important finding was that reconciliation is highlighted rather than authority. In a Confucian scholar, it is focused on love and benevolence between a teacher and a student by having humanity as the foundation and courtesy as ways and means. Also a Confucian scholar has demanded a good moral character and professional qualifications of a teacher. This study concludes that teacher's authority is made by teacher's professionalism, social roles and spirit of benevolence; also it has been making a conception of a teacher in Confucian scholar tradition. This study suggests that it needs to re-think about the values and meaning of Asian tradition in our educational settings in which western culture and values is influencing Asian societies too much.

The purpose of this study was to investigate elementary school teachers' conceptions on the general remarks (GR) in the new science teacher's guide, the teachers' conceptions on inservice training program of the GR, and their opinions of improvement on the GR. Also, the teachers' utilization of the GR was examined. The participants were 152 elementary school teachers who were teaching grade 3~6. A questionnaire was used to collect data. The results of this study are as follows; First, at least 13.2~17.1% of the teachers did not have specific conception of the purpose of the GR, and more than 90% of the teachers expressed that the GR is necessary in the teachers' guide. Second, about 60% of the teachers responded that the training program on the GR is necessary, and when the program is open, their most favorite agency and speaker were a provincial education office and a textbook developer(or author), respectively. Their most favorite time and period of the training program were the vacation and 15~30 hours, respectively. Third, the mean values on the frequency of use were lower than 3 point of the five-point Likert scale at both the GR for grade 3~4 and the GR for grade 5~6, and the teachers' main use of the GR was the planning a science lesson for an open class. Fourth, the teachers suggested various opinions and there was difference between the opinions about the GR for grade 3~4 and the opinions about the GR for grade 5~6.

This study was done to examine parents, peer, teacher attachment, depression, and self-conception in adolescents. A survey using a structured questionnaire was conducted with 2,3 grade students of middle school located in 137 subjects. Data were analyzed using an independent t-test, one-way ANOVA, Pearson's correlation, and multiple stepwise regression analysis with the SPSS WIN 22.0 program. There was a significant difference in parents attachment(F=13.878, p<.001), peer attachment(F=7.431, p<.001), teacher attachment(F=7.425, p<.001), depression(F=13.241, p<.001), and self-conception(F=13.136, p<.001) according to participants' school grades. In the correlations of study variables, self-conception showed statistically significant correlations with parents, peer and teacher attachment in aspects of positive, and depression in aspect of negative. Participants' depression explained 61% of variance in self-conception. Findings from this study should be useful in the development of programs to promote participants' self-concept through their depression as a major problem in adolescent mental health.

The aims of this research are to analyze elementary preservice teacher's conception and causes of their misconceptions on biological reproduction and inheritance. In future, it would be also to provide useful data for the effective teaching-teaming method in the elementary school as well as opportunities to correct their misconceptions, which help elementary preservice teachers have the appropriate scientific conceptions. Thirty kinds of test questions were designed in science curriculum for elementary students and biology textbook for university students in order to develop reproduction and inheritance's concepts. The questionnaire was given to 166 junior students of university of education in a local city. All statistical analysis was performed using SPSS version 10.0 program. The major results are as follows: Among 30 test questions, 2 questions in plants, 5 questions in animals and 2 questions in gene were appeared as misconceptions over $50\%$. The major reason to hold the misconceptions was influenced by 'learning up to now' category. The selection reasons of response were significantly different between scientific conceptions and misconceptions in 10 questions by analysis of variance. The gender also showed statistically significant differences between scientific conception and misconception in 3 questions by $\chi^2$ test. The selection reasons according to gender were significantly different between male and female students in 5 questions. For the reasons in forming misconceptions, they may cause by stereotype, conscious priority, differences of experiences, interest or attention, lack of professional Knowledge, and so on. Therefore, it was concluded that this research may help elementary preservice teachers to reconsider their conception for reproduction and inheritance and to be successful in science instructions fur elementary students.

Prospective teachers need to have an opportunity to critically examine their initial perception with regard to effective mathematics instruction during the teacher education period. This study analyzed the perception in relation to good mathematics instruction by a total of 265 prospective teachers from four institutes for elementary teacher education using a survey. The results of this study showed that the pre-service teachers regarded learner, teaching and learning method, selection of content, and construction of curriculum as important for high-quality mathematics instruction. However, they revealed relatively low levels of agreement against the importance of instructional materials, classroom environment and atmosphere, and assessment. On the basis of teachers' perception on each element of effective mathematics instruction, this paper raises issues for discussion and includes some implications for teacher education.

Teachers' conceptions about teaching are important driving and also interfering forces which might affect their actual practice and training. This research explores preservice mathematics teachers' conceptions of teacher discourse, through tasks analyzing and evaluating teachers' moment-to-moment discourse moves which occur in authoritative and dialogical classroom discourse. Some facets of the preservice teachers' conceptions were congruent with dialogical discourse: they criticized teacher's one-way communication and ignoring students' voices; they supported teacher's questions probing students' thinking and receptive attitude to ward students' wrong answers. However, some deep and subtle facets of their conceptions were more congruent with authoritative discourse rather than dialogical discourse: they positively perceived teacher's closed, information seeking questions that funnel students' thinking to the predetermined procedure; they emotionally resisted teacher's questions which might facilitate dialogical engagement by allowing students to judge mathematical correctness of ideas from their peers. Preservice teachers' conceptions of teacher discourse explored in this research provide useful foundations on which to build continuous and coherent teacher professional development programs about classroom discourse.

In order to study the effect of student's conceptions about force and motion into the graph construction in kinematics in college physics course, the tasks of constructing the qualitative graph in the similar problem context used in force conception was asked to the first 74 and third 97 student teacher in teachers' university. The frequencies analysis showed that student teachers had the naive conceptions that the throwing force was still acted to a upwarding ball. They also had the popular Aristotelian views about motion. These naive conceptions coexisted with the scientific conception about gravitational force. In a simple pendulum problem no one had the correct acceleration concepts which varies the direction in swing. This result suggest that student teacher had more difficulties in a acceleration problem than in a velocity problem In v-t and a-t graph construction tasks, the number of categories of a-t graphs were more than that of v-t graphs. There were many graph errors in a sign of velocity and acceleration. The acceleration conceptions without the relations of changes in velocity made the kinematics graphs more various shapes. The force and motion conceptions influenced the ability to construct the kinematics graphs.

The purpose of this study was to investigate elementary student teachers' conceptions about the mechanism of the greenhouse effect, the greenhouse gases, the global warming, and their learning experiences of the greenhouse effect and the global warming. Participants were 82 student teachers in their second year of studies (science education: n=28, not science education: n=27) and in their fourth year of studies (science education: n=27). The open-ended questionnaire was used to examine the teachers' spontaneous ideas depicted by their drawings and/or writings. The results of this study are as follows: First, the student teachers' scientific response rate about key concepts related to the mechanism of the greenhouse effect was low (6.1%~28.0%); Second, although there are various greenhouse gases, it was only carbon dioxide that the student teacher's response rate was more than 80%; Third, only 17.1% of the student teachers clearly distinguished the greenhouse effect and the global warming; Fourth, there was a tendency that the student teacher group in the fourth year of studies and science education showed higher scientific response rate about the concepts than the other two groups.
