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.

본 연구는 교사의 권위가 약화되고, 교사와 학생의 관계가 각박해지고, 교사의 역할과 전문성 문제에서 논의가 엇갈리고 있는 우리 교육의 현 시점에서, 유가(儒家)전통의 교사상을 재 고찰해보는 것을 목적으로 하였다. 이를 위해 교사상을 권위상(權威像), 인애상(仁愛像), 사범상(師範像)으로 나누어 논의하였다. 유가의 전통에서 교사의 권위는 이성적 권위이며, 사회적 제도와 교사의 사회적 역할의 산물이고, 더 중요한 것은 권위보다는 화해를 강조하고 있었다. 유가전통에서는 인(仁)을 근본으로, 예(禮)를 그 방식과 수단으로, 교사와 학생간의 사랑과 정을 중시하고 있었다. 또 유가에서는 인간의 모범으로서, 교사의 양호한 도덕품성과 전문적 자질을 요구하고 있었다. 교사의 전문성과, 사회적 역할 그리고 인애(仁愛)의 정신이 교사의 권위를 형성하였고, 또 전체적인 유가 전통의 아름다운 교사상을 형성해왔던 것으로 보인다. 따라서 본고는 서양의 문화와 가치관의 영향을 많이 받고 있는 동양 사회의 현실에서, 우리의 교육현장에서 다시금 동양전통의 가치관과 그 의미를 재 사고해 볼 것을 권고하고 있다.

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.

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.

본 연구에서는 권위적 및 대화적 담화 사례의 교사 담화 평가에서 드러난 예비 수학 교사들의 인식을 질적 내용 분석으로 탐색하였다. 예비교사들은 교사의 일방적 설명이나 학생 대답을 적극적으로 수용하지 않는 폐쇄적 발화에 비판적이었으며, 학생의 이유를 탐색하는 질문과 오답에 대한 개방적 태도를 지지했다는 측면에서 표면적으로 대화적 담화를 지향하고 있었다. 그러나 교사가 대부분의 인지활동을 대행하는 테스트 질문에 무비판적이었고, 학생들에게 제기된 답에 대한 수학적 판단 기회를 부여하여 대화적 상호작용을 촉진하는 교사 발문에 대해 심리적 저항을 보였다는 점에서, 예비교사들의 심층적인 권위적 담화 지향성도 확인할 수 있었다. 본 연구에서 보고한 교사교육 입문 초기 예비교사들의 담화인식은, 교실 담화에 대한 교사 전문성 교육 과정 설계에 유용한 기초를 제공할 수 있을 것이다.

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.
