This study investigated pre-service elementary teachers' understanding of the planetary revolution movement of Mars and their explanatory models to show how the Sun-Earth-Mars system worked. An assessment item set using five celestial maps drawn from the Stellarium was designed to probe pre-service teachers' understanding of the prograde-retrograde motion of Mars. Among 23 participants, only four showed scientifically accurate understanding of Mars movement and drawing correct explanatory models for the planetary movement. Even the pre-service teachers who construed correctly prograde and retrograde motions of Mars showed a clockwise movement model due to their intuitive perceptions of Mars movement data from the celestial maps. Pre-service teachers with poor understanding of planetary movement also showed weak explanatory models due to their limited observation or lower spatial thinking. Although the planetary motion is not an easy topic for pre-service elementary teachers, it can be argued if the alternative approach, such as using appropriate observational data of a planet and changing the frames of reference between Earth-based view and Space-based view, is employed effectively in teaching planetary motion, pre-service teachers can reach the upper level of leaning planetary motion in terms of the planet's revolution.

We have examined the perception of teachers and students in elementary schools toward the frontier science and analyzed corresponding contents in science textbooks in Korea and the U. S. in order to promote a good guidance for the frontier science education. We prepared separate questionnaires for teachers and children, respectively, and analyzed the responses obtained from 244 teachers and 1,000 students in five elementary schools. For the analysis of how to introduce the frontier science, we investigated textbooks such as Science, Society and Practical Arts of Korean elementary school, and an American science textbook published by Scott Foresman. This study revealed that teachers are well aware of the importance of the frontier science, however, they are inactive in conducting the subject in class rooms because of their insufficient scientific knowledge and poor environment for teaching. It has been found that children had strong interest in the frontier science, however, opportunities to learn the topic are not properly provided. The frontier science m the American science textbook turned out to be more systematically introduced than that in Korean ones.

이 연구에서는 Draw-A-Science-Teacher-Test Checklist(DASTT-C)를 이용하여 국내 초등교사들의 과학 교수에 대한 자기 이미지의 특징을 조사했다. 서울시, 경기도, 강원도 지역의 초등교사 178명을 대상으로 설문조사를 실시했다. 연구 결과, 국내 초등교사들의 과학교수에 대한 자기 이미지는 4개의 과학 과목(물리, 화학, 생물, 지구과학)에서 모두 '학생 중심'보다는 '교사중심'인 경향이 강했다. 이는 초등교사들의 과학 교수관이 구성주의보다는 전통주의적인 경향이 강할 가능성을 시사한다. 따라서 구성주의에 기초한 예비 및 현직 교사교육과정을 효과적으로 설계하는 방안을 마련할 필요가 있다.

본 연구의 목적은 한국 초등 예비 교사들의 '수학을 가르치는데 필요한 지식'(MKT)을 분석한 후, 권민성 남승인 김상룡(2009)의 결과들과 비교 분석함으로서 교육대학에서의 초등수학교과 교육을 개선할 수 있는 시사점을 제공함에 있다. 연구를 수행하기 위해 권민성 외에 의해서 한국어로 번안된 수와 연산에 관한 MKT 설문지를 사용하여 J 대학교 교육대학에 재학하고 있는 88명의 초등 예비 교사들을 대상으로 MKT를 측정하고 권민성 외의 결과와 비교 분석하였다. 그 결과는 다음과 같다. 첫째, 초등 예비 교사들이 수와 연산에 관하여 이미 알고 있는 '내용지식'(CK) 정도는 긍정적이었으나 '내용과 학생에 대한 지식'(KCS) 정도는 부정적으로 나타나 이들의 KCS에 대한 교육을 강화할 필요가 있다. 둘째, CK 및 KCS 문항들에 대한 초등 예비 교사와 교사가 느끼는 문항 난이도는 강한 상관관계를 보였다. 셋째, 초등 예비 교사들은 교사들보다 교실수업에서 MKT 문항들의 활용성을 더 높게 평가하는데도 불구하고, 약 70%의 초등 예비 교사들은 MKT 문항들이 교육대학에서 배운 내용이 아니라고 응답하였고 일부 문항에 대해서는 교사들과 다른 관점을 가지고 있었다. 본 연구 수행에서 얻은 시사점은 다음과 같다. 첫째, 초등 예비 교사들의 MKT를 향상시키기 위해 J 대학교 교육대학 초등수학교과교육의 개선이 필요하며 둘째, 우리나라 초등 예비 교사의 MKT를 정확하게 측정하기 위해서는 우리나라의 학교와 교육과정에 적합한 MKT 항목들을 개발할 필요가 있다.

The study aims to figure out pre-service elementary teachers' knowledge understanding on 'stratum and rock' as well as teaching-learning types on the same topic. A total of 65 seniors in an advanced science education course at B University of Education joined the research to fulfill the purpose above. With PCK classification framework, the study examined pre-service teachers' knowledge understanding on 'stratum and rock' while it analyzed how the teachers would teach the given topic to students. The results of the study are presented as follows. First, it was observed that the pre-service elementary teachers have a great understanding on 'stratum and rock' that would be taught via a science textbook for elementary fourth graders. However, regarding terms in 'shale and limestone', they appeared to have a relatively short understanding. Second, PCK elements of the pre-service teachers related to 'stratum and rock' were analyzed and according to the results, the teachers would be interested in teaching model selecting in the teaching-learning strategy field while they would be well aware of how important it is for them to perform an experiment in a teaching process. The teachers also appeared to understand that the teacher question can be mutual complementary during class. However, it turned out that the teachers would have a very much low understanding on learners' prior knowledge as they particularly believe that learning could be significantly affected by the learners' perception level as well as their learning interest and motive. Third, the pre-service elementary teachers were told to design teaching plans on 'stratum and rock' so that the study could find out what learning-teaching methods the teachers would adopt to teach the topic. It was learned that the teachers would proceed with the class basically by giving the learners a descriptive explanation on the topic and also by using pictures and drawings to enhance the learners' understanding during the class.

The purpose of this research is to analyze Korean teacher textbook use and explore the effective use of textbooks. The researcher surveyed teachers to obtain information relative to their dispositions and views of textbook use, and a subset interviewed to obtain additional insight about these views. For the sample, 278 elementary school teachers were surveyed and a group interview was conducted with 6 teachers. The results showed that many teachers teach all the students simply by following the textbook content. These results suggest that for effective us of textbooks, teachers need to understand how to reconstruct the textbook within an understanding of the textbook authors' intension for the textbook content.

This study is observed in this paper that how the mathematical beliefs of elementary pre-service teachers are reflected in planning and implementing actual mathematics classes. The subjects for this study are senior students at the university of education. After examining their mathematical beliefs and analyzing their actual mathematics classes in a teaching practicum, the following conclusions are drawn. First, the mathematical beliefs of elementary pre-service teachers have generally shown in a similar tendency. The beliefs formed by the students' experience and the beliefs established in the course of preparing to become teachers have coexisted. Second, the teachers' belief in learning mathematics and the teaching practices are largely inconsistent. Third, when elementary pre-service teachers plan and implement their mathematic classes, they are influenced by their guidance teachers and students as well as their own mathematical beliefs.

The purpose of this study was to investigate what elementary teachers know about students' science misconceptions and how the teachers plan for and address their students' misconceptions in instruction. The sample included 61 teachers who participated in a teacher training program irrelative to science education. A questionnaire into which Gomez-Zwiep's semi-structured interview questions was transformed was used to examine the teachers' understandings of definition, origin, examples, and so on of science misconceptions, and their instructional strategies for addressing their students' misconceptions before and while instruction. The results showed that many teachers (about 60%) did not have appropriate understanding of students' misconceptions, that the majority of the teachers (about 75%) did not consider misconceptions at all before teaching science lessons, and that almost all the teachers (about 90%) did not know particular strategies specifically designed for misconceptions.

The purpose of this study was to provide the basic data for development of consulting model in elementary science class. For this, some questions on the teachers' perception for science instruction were surveyed to teachers : 13-item-questionnaires were given to 233 teachers in elementary school. The results of this study were as follows: Most of teachers were little understanding and experience of the science instruction consulting. They sensed that their science instruction were difficult, especially experimental activity in science class. They desired consulting mightly in their teaching methods for experimental activity. And it was found that most of them had a mind of consulting participation. Thus it is necessary to inform them the need of the instructional consulting. And in case of the development for the consulting manual, it should be consider the above results.
