The purpose of this study was to identify the relationship among beginning early childhood teachers' role performance and self leadership, and childcare teachers's supports. The subjects in this study were 491 beginning early childhood teachers working in kindergartens and child care centers across the country. Childcare teachers' support questionnaire(Jae-Young Lee, 2012) role performance questionnaire(Bog-Mae Park, 2011), and self-leadership questionnaire(Dong-Hyen Park,2014) were used for this study. For the research analysis, frequency, Cronbach's ${\alpha}$ coefficient, ANOVA test, $Scheff{\acute{e}}$ post-hoc analysis and Pearson's correlation were calculated and regression analysis were conducted. The results are as follows. Firstly, it was revealed that there are statistically meaningful differences in beginning early childhood teachers 'role performance and self leadership, and childcare teachers's support which were related to early childhood teachers' salary, education background, and age. Also, there are statistically meaningful differences in beginning early childhood teachers' role performance and childcare teachers's support, which were related to type of child-care center role performance, but there were no differences in beginning early childhood teachers' self leadership. Secondly, childcare teachers's support have statistically meaningful positive influences on beginning early childhood teachers' role performance through the mediation of self leadership. Through this study, it is possible to provide basic information to seek ways to enhance beginning early childhood teachers' role performance and self leadership under the considerations of their individual background characteristics, and to promote the practical support for the director or colleagues.

This paper tries to examine differences between geography classes taught by majored and non-majored teacher and to find problems in the latter case, tv observing four middle school geography classes in Seoul, from April to May 2003. The observation was fecund on (1) organization of a class (2) dialogue between teacher and students (3) strategy of explanation. In addition, the author conducted personal interviews with social studies teachers in the schools where the observations were made. The analyses of the observed classes were made by micro-ethnographic research method. Major findings of the observation and analysis are as follows. First, the transition from one topic to another topic was not smooth in the case of non-majored teacher class. Second, the questions that the non-majored teacher posed in the classroom played less significant role in keeping up the class in an organized fashion than those that the majored teacher posed. Third, the non-majored teacher focused on the concepts, terms and contents appeared in the textbook and simply tried to explain them, whereas the majored teacher demonstrated teaching methods such as comparing and contrasting cases to provide students with a more dynamic and comprehensive understanding on the topic they teamed. Fourth, the non-majored teacher used maps less frequently and less actively than the majored teacher. In addition, although the non-majored teachers are well aware of their problems in the class as a non-majored teacher, they think that the problems are inevitable in a given curriculum structure of social studies in Korea.

본 연구에서는 교사의 전문성 영역의 한 부분인 학생 평가 전문성을 교사 스스로 진단해 보고 진단 결과에 대해 적절한 처방을 제공받을 수 있는 교사의 학생 평가 전문성 자기진단 프로그램을 개발하고자 하였다. 이를 위해 선행 연구와 문헌 조사를 통해 교사의 학생 평가 전문성을 구성하는 요인을 규명하고 이를 범주화하여 학생 평가 전문성 진단 도구를 구안하였다. 교사의 학생평가 전문성 구성 요인은 1990년에 미국의 AFT(American Federation of Teacher), NEA(National Education Association), NCME(National Council on Measurement in Education)가 공동으로 발표한 ‘학생 평가를 위한 교사의 평가전문성 기준(Standards for teacher competence in Educational Assessment of Student)’ 7가지를 연구자가 진단 도구 개발에 적합하도록 ${\circled1}$평가 방법의 선정, ${\circled2}$평가 도구의 개발, ${\circled3}$평가 실시?채점 및 성적 부여, ${\circled4}$평가 결과의 해석?분석?활용?의사소통의 4개 영역으로 재구성하였다. 진단도구를 개발하는데 있어서는 전문성 구성 요인별로 설문 형식의 질문에 답하고 이를 종합하여 점수를 매기는 방식보다는 구체적인 상황과 사례를 제시하고 이에 대해 평가를 해보게 하는 방식을 이용하여 평가 능력을 실질적으로 진단할 수 있게 하는데 초점을 맞추었다. 개발된 프로그램은 교사가 외부로부터 평가 받는데 소극적인 점을 감안하여 교사 스스로 자기를 진단할 수 있는 도구를 제공하고자 했으며, 진단 도구를 통해 밝혀진 결과에 대해 처방이나 안내를 함께 제공하여 교사가 자신의 평가 전문성을 제고하는데 보다 적극적으로 나설 수 있도록 도울 수 있는 프로그램으로 개발하려 하였다. 또한 이 프로그램을 교사가 활용하는 과정에 대한 조사 연구를 통해 궁극적으로는 교사의 학생 평가 전문성 신장을 위해 필요한 외부 지원이 무엇인지 추출하고 이러한 지원 체계와 교사가 능동적으로 이어질 수 있는 방안을 모색해 보고자 한다.

This study is conducted to analyze the questioning styles of the parts of chemistry in 17 middle school science textbooks in terms of frequency, types, and placement of questions. The instrument was the Textbook Questioning Strategies Assessment Instrument (TQSAI) developed by the Cooperative Teacher Preparation Program, University of California in 1975. An averaged ratio of questionings/sentences (Q/S) of seventeen textbooks was 13.6% varying from 6.8% to 19.7%. Various question types were used in titles, early and middle steps in the sections except late steps. The comprehending questions were most frequent in the types of inquiry courses and the focusing questions were most frequent in the characteristics of instructional courses. The percentages of empirical questions for the total numbers of questions were slightly larger than nonempirical questions with values of 54.2% and 45.8%, respectively.

The purpose of this study is to reveal the insights that teachers has learned through developing preschooler's classroom into field-trip-oriented ones with role play areas. The data of this study was collected from participatory observation and in-depth interviews, which included videos, photos, teachers' journal, descriptive questionnaire, and interview records. The whole process of organizing role-play oriented class was composed of four steps: activities before the trip, activities on-the-spot, activities after the trip, and its evaluation. Firstly, activities before the trip were making the lists of questions, deciding children who ask the questions, making rules on the trip, understanding the purpose of the trip. Secondly, on-the-spot activities included having a tour of the place and asking the questions. Thirdly, activities after the trip was constructing the classroom into small real world with various sections. This required the teachers to reflect the field trips, make plans how to construct, prepare for the data, and furnish the classroom with role-play areas. In the process of furnishing the classroom with small real world, the field trips played a big role as the learning opportunities for language development, and keeping public rules.

The purpose of this study is to identify the conceptions of elementary school teachers regarding the variation scale about astronomical distance and its accuracy with distance increased. The astronomical distance questionnaire was administered to 69 elementary school teachers, then; three teachers were selected to interview about their conceptions. Results showed that many elementary school teachers overestimated the distance from the Earth to the Moon and to the Sun, and dramatically underestimated the distances to the nearest star and to the nearest galaxy. They inferred astronomical distance with the use of both intuitive (psychological) measure and theoretical (calculative) measure. They well recited the terminology such as AU and a light-year, yet they did not show a good understanding of what the terms exactly means. Some teachers thought that the distance to Neptune is farther than the distance from Earth to the nearest star. There was a considerable variability in the participants' estimates of astronomical distances. Elementary school teachers showed a tendency to overestimate the distance as it gradually increases to the outer solar system.

In this research, we have developed a "computer tutor" that mimics the human tutor with animated tutoring dialog agent and the agent was integrated to teaching-learning material for elementary science subject. The developed system is a natural language based teaching-learning system using one-to-one dialogue. The developed pedagogical dialogue teaching-learning system analysis student's answer then provides appropriate answer or questions after comparing the student's answer with elementary school level achievement. When the agent gives either question or answer it uses the TTS(Text-to-Speech) function. Also the agent has an animated human tutor face for providing more human like feedback. The developed dialogue interface has been applied to 64 6th grade students. The test results show that the test group's average score is higher than the control group by 10.797. This shows that unlike conventional web courseware, our approach that "ask-answer" process and the animated character, which has human tutor's emotional expression, attracts students and helps to immerse to the courseware.

This study explored pre-service teachers' mental models about eclipse phenomena to investigate their understandings on the earth science concept needed f3r an integrated approach. We conducted in-depth interviews with two different contexts on 30 secondary and 36 primary pre-service teachers participants, and analyzed phenomenological primitives (p-prims) and facets of causal explanations about eclipses. Based on this study, we identified four different levels of mental models about eclipses. Four mental models were categorized as (1) Screening model, (2) Orbital plane model, (3) Hybrid model, and (4) Shadow cast model. Screening model is a flawed mental model, orbital plane model is an incomplete correct mental model, and shadow cast model is a scientifically correct mental model. Hybrid model, composite of two or more mental models, use multiple mental models simultaneously. Orbital plane model was the most widespread mental model in secondary pre-service teachers group, whereas screening model was used frequently in primary group. It was found that the level of mental model could be determined by the level of facet and p-prims. We confirmed context sensitivity of the mental models and perceived the necessity of integrated approaches to promote progression of mental models. Implications of our findings for enhancing pre-service science teachers' topic-specific pedagogical content knowledge (PCK) associated with eclipse phenomena are also discussed here.

The purpose of this study was to examine the flow of teacher-student verbal interactions and the types of discourse in the science gifted classes of three effective teachers. The three effective teacher were recommended by the expert of a gifted education or science education expert. A participant observation was carried out in their classes, and all the classes were videotaped. The collected videotape materials were transcribed, and Flanders Interaction Analysis Categories and an AF program were utilized to analyze the video clips. The findings of this study were as follows: First, there was no specific flow of verbal interactions in the classes provided by the effective gifted teachers, but the kind of positive verbal interaction that the students responded diversely to their questions or lectures took place. Second, the most prevalent type of utterance in the classes of them was lecturing, and the remark of direction and criticism scarcely took place. And lots of non-directive remarks were found such as emotional acceptance, praise, encouragement or acceptance of ideas. As a result, the effective science gifted teachers made more nondirective remarks such as emotional acceptance, praise, encouragement and acceptance of ideas than directive remarks such as direction or criticism, and their non-directive remark made it possible to elicit more extensive responses from their students.
