This study was conducted on 115 students from 4 classes of 2nd year intensive courses at B University of Education. Elementary preservice teachers were surveyed on what teaching methods they were aware of regarding the subject of elementary science astronomy. Recognition data of 80 people from whom the questionnaire was collected were analyzed. For this study, a 5-day survey was conducted. Elementary preservice teachers complained of difficulties in teaching methods in the astronomy area among various areas of the science department. The purpose of this study was to find out what difficulties elementary preservice teachers have in teaching elementary science astronomy topics, and to find more efficient teaching methods for teaching astronomy topics. The topic of the survey was set by discussing with the preparatory elementary teachers about what kind of survey to use in teaching the subject of elementary science astronomy. There are many topics for elementary science astronomy, but two questionnaires were prepared focusing on the unit on the earth and the moon. 'What does the earth look like?' in Unit 4 (1/10) of the 3rd year, 1st semester In Unit 2 (1/11) of the 1st semester of the 6th grade, it was set as 'What does the moon look like?'. Candidly describe how to teach the subject of astronomy to elementary school students by mobilizing all the background knowledge of preparatory elementary teachers. The results of these surveys were visualized and displayed using Netminer as a language analysis method, and the contents of the responses to the actual surveys by pre-service elementary school teachers were described and interpreted. Based on these results, preparatory elementary teachers tried to suggest a more efficient teaching method for the subject of elementary science astronomy. In addition, basic procedures and methods for lecturing on the subject of elementary science astronomy were presented. A more efficient teaching method for teaching elementary science astronomy subjects to pre-service elementary teachers was suggested.

It is important to understand how pre-service teachers perceive e-learning because their prior-experience with e-learning will have a great impact on their teaching after the graduation. Pre-service teachers (401 students) with cyber learning experience, which is a form of e-learning, were selected in 2004 in May and June. Survey was conducted regarding the instructional experience (working hours, tasks and evaluation, satisfaction about cyber learning and its academic achievement, difficulties and suggestions) and instructional methods (instructional activities, frequencies of interaction, strategies of interaction, collaborative activities, behaviors in the group instructional activities for knowledge development). The results are pre-service teachers tent to spend similar v slightly less working hours for cyber learning, similar or slightly less satisfaction level for the instruction and the academic achievement. It was interesting that female students were more negative than males students, considering female students have been more active in online discussion traditionally. Logical presentation of contents and instructional strategies for the cyber learning were the most wanting suggestions. E-mails and BBS for reference materials were the two most used functions in the online learning. The amount and types of tasks were satisfactory. Students did not interact freely during the group activities, they reported they did not learn much through the group activity. During the group work, they consider they do their roles with responsibility while they have slightly negative responses toward other members' contribution in the group activity. Off line meeting is strongly suggested.

The purpose of this study is to verify the effect of participating in teaching material development program using 3D printer on the recognition of universal design for learning of early childhood special education pre-service teachers. This study was conducted on 30 early childhood special education pre-service teachers who participated in teaching material development program using 3D printer. The results of this study showed that the early childhood special education pre-service teachers use of the 3D printer-based teaching material development program resulted in statistically significant differences in the 4 low rank factors of the universal design for learning. This research shows that direct experience in developing teaching material using 3D printers is very effective to improve universal design for learning awareness. In addition, the experience of developing teaching material for pre-service early childhood teachers is important for improving the instructional design ability, and they need the practice of the development of the teaching material using the latest technology for teaching students with various needs.

The study aimed at investigating preservice elementary school teachers' statistical reasoning when they posed survey questions as they engaged in statistical problem solving, and analyzing how their statistical reasoning affect the subsequent stages. 24 groups of sophomore students(80 students) from two education universities conducted statistical problem solving and completed statistical report, and 22 of them were analyzed. As a result, 9 statistical reasoning were shown when preservice teachers posed survey questions. Among them, question clarification oriented reasoning and variability based reasoning were not exclusively focused upon in the previous research. In order to investigate how statistical reasoning in posing survey questions affected subsequent stages, we examined difficulties and issues that preservice teachers had when they engaged in analyses and conclusion stage described in their report. Consequently, preservice teachers' difficulties were related to population relevant reasoning, category level reasoning, standardization reasoning, alignment to question reasoning, and question clarification oriented reasoning. While previous studies did not focus on question posing stage, this study claimed the necessity of emphasizing various statistical reasoning in question posing and importance of teaching and learning method of appropriate statistical reasoning in question posing.

This study analyzes several factors of good instruction that have been studied by precedent studies as well as the dominated perspective of teaching that validates the value of good instruction. For this purpose, the authors explore an understanding of the perspective that lessons ought to pursue. The authors examine the difference in the dominated perspective of good instruction of pre-service teacher and teachers through the study methodology of chi-square, one-way analyses of variance, and post-hoc test. The research subjects were enrolled students and graduates of the Department of Early Childhood Education at colleges in Seoul and the Capital area. The TPI that had been objectively indexed with comprehensive understandings and viewpoints of good instruction was also applied. The study result shows that high schools' dominated perspective is "nursing" and colleges' is "apprenticing", regardless of the kind of school. The article discusses the perspective of good instruction by comparing the results of domestic and foreign studies and this study. Some ideas were suggested for further research.

The purpose of this study is to confirm how keeping a educational diary in which no feedback is given in the teaching practice in kindergartens affects a teacher efficacy and the educational belief of preschool teachers-to-be as well as the organizational health of kindergartens to practice according to the way teachers feel. With this aim, the study aimed at 34 seniors at the Department of Early Childhood Education in the four-year college in Chungnam. The study conducted this experiment using the nonequivalent control group pretest-posttest design, and carried out a $x^2$ analysis and a t-test according to the data. Concerning the research results, first, keeping a educational diary of teaching practice affirmatively affected a teacher efficacy. Second, it did not significantly affect a teacher's educational belief. Third, it did not significantly affect the organizational health of the kindergarten to practice according to the ways teachers-to-be feel. This study is meaningful in that keeping a reflective journal in which feedback by a guidance teacher for practice becomes the basic proposition may be replaced with the keeping of a diary of practice at the level of practicality. This means that a teacher's sense of efficacy may improve simply by keeping a educational diary of teaching practice without feedback by a guidance teacher.

The purpose of this study was to investigate pre-service elementary teachers' conceptions about the relative sizes of celestial bodies including the universe, galaxy, star, planet, satellite, asteroid, and comet, which were presented in elementary school science textbook. This study also examined the causes of their misconceptions as shown in the study. Sixty three pre-service elementary teachers participated in this study. The survey was developed for this study that asked to make an order of relative sizes of the given celestial bodies and to write scientific facts about each of the celestial bodies. The survey items were analyzed by simple descriptive statistics, and the written responses were analyzed using qualitative and inductive methods. The results showed that only five (7.9%) of the participants correctly answered about the relative size of the given celestial bodies. There were three common misconceptions identified in relation to the relative sizes of the celestial bodies; more than 20% of the participants had: (1) a planet is bigger than a star (46.0% of the participants), (2) an asteroid is bigger than satellite (58.7%), 3) a comet is bigger than a star (22.2%).

It is important to pay attention to how teachers recognize and use curriculum materials in order to link written curriculum and enacted curriculum. In this study, 90 preservice mathematics teachers were surveyed to identify their perspective and reading of curriculum materials. Especially, we focused on the curriculum documents, textbooks, and teachers' guidebooks containing the concept of conditional probability which is addressed in highschool mathematics curriculum. The various misconceptions of conditional probability were reported in the many researches, and there are multiple methods to introduce conditional probability in mathematics classes. As a result, curriculum materials have some limits to be used as they are and considered to be reconstructable by participants, but their curriculum reading were mainly classified to be descriptive and evaluative, not to be interpretive. However, unlike curriculum documents, textbooks and teachers' guidebooks were partially interpreted by participants using their knowledge of conditional probability. The purpose of this study is to investigate the profession of mathematics teachers in terms of curriculum implementation. We expect that this study will provide a basic framework for analyzing mathematics teachers' works and suggest some implications for the professional development of mathematics teachers.

The purpose of this study was to determine the factors affecting the satisfaction with pre-service childcare, the work related stress, and the conflicts perceived by pre-service childcare teachers. The data was processed using the SPSS Statistical Package Program, and the frequencies, means, and standard deviations were calculated. Reliability analysis, correlation analysis, and multiple regression analysis were also conducted. The results showed that the class contents, the environment of childcare practice, and the conflicts with children were stressful and they negatively affected practice satisfaction. Second, there was statistically significant negative correlation between the pre-service teachers' childcare practice stress, conflict during the practice, and practice satisfaction. Third, the stress of preservice teachers' childcare practice and the conflict felt during the practice also affect the childcare practice satisfaction. Based on these findings, further study is needed for implementing effective measures in order to improve the practice satisfaction with exhaustive pre-practical education and the field job-oriented curriculum. These measures will enable students majoring in childcare to experience less stress and conflicts during their education.

In current computer education, we have inclined to emphasize information literacy for k-12 students. On the other hand, in spite that teachers are core variable in school education system, we have neglected teacher's education of information and communication technology. In addition, we haven't made a effort to expand preservice teacher's ability to utilize information and communication technology in the teacher's college and the college of education. With these recognitions, we made a diagnosis of problems by analysis of current condition of curriculum of the teacher's college and the college of education and explored the vision of ICT utilization education in k-12 computer education in this study. In addition, we suggested educational objectives and contents based on national requiring standards for ICT in teacher preparation, required ICT capability of preservice teachers for kind of teacher's task and the direction of computer education.
