Astronomy is a good area to introduce a student to the study of science. The student often questions what causes the change in seasons, in the day and right, and in the rotation of stars, etc. Attempts to find answers to problems related to these astronomical observations influence the student`s intellectual development. This study is to investigate the effect of running an astronomical observations program on the preservice elementary teachers' astronomy achievement, astronomy teaching efficacy beliefs, and scientific attitude. Students consist of twenty four preservice elementary teachers. Three instruments are used: one is the astronomy achievement test, which is of an essay type, and 5 items. The other is the astronomy teaching efficacy beliefs test, which is of a Likert scale type, and 22 items. Another is the scientific attitude test, which is of the Likert scale type, and 10 items. Data are collected before and after instruction in the astronomical observations program, through the use of these tests. Data are compared. The results are: \circled1There is a significant difference between before and after instructions in the astronomy achievement test(t=11.31, p=000). \circled2There is a significant difference between before and after instructions in the astronomy teaching efficacy beliefs test(t=5.98, p=.000). \circled3There is a significant difference between before and after instructions in the scientific attitude test(t=270, pde. There fore, the a=.013). As a result, running an astronomical observations program has an effect on the preservice elementary teachers' astrono my achievement, astronomy teaching efficacy beliefs, and scientific attituuthor urges the teacher to teach astronomy through the astronomical observations in school.

In general, the intuitive knowledge that can use in mathematics problem solving is one of the important knowledge to teachers as well as students. So, this study is aimed to analyze the elementary preservice teachers' intuitive knowledge in relation to intuitive and counter-intuitive problem solving. For this, I performed survey to use questionnaire consisting of problems that can solve in intuitive methods and cause the errors by counter-intuitive methods. 161 preservice teachers participated in this study. I got the conclusion as follows. preservice teachers' intuitive problem solving ability is very low. I special, many preservice teachers preferred algorithmic problem solving to intuitive problem solving. So, it's needed to try to improve preservice teachers' problem solving ability via ensuring both the quality and quantity of problem solving education during preservice training courses. Many preservice teachers showed errors with incomplete knowledges or intuitive judges in counter-intuitive problem solving process. For improving preservice teachers' intuitive problem solving ability, we have to develop the teacher education curriculum and materials for preservice teachers to go through intuitive mathematical problem solving. Add to this, we will strive to improve preservice teachers' interest about mathematics itself and value of mathematics.

Teachers' ability to notice is a crucial indicator of their instructional expertise. Despite the significance of this ability, research in mathematics teacher education has predominantly focused on the noticing of preservice teachers, with limited exploration into the noticing abilities of experienced in-service teachers. This study addresses this gap by examining the noticing characteristics of in-service elementary teachers actively developing their competency in elementary mathematics education. For this purpose, 23 elementary school teachers were asked to complete an analysis sheet while viewing the mathematics lesson video depicting on the concept of (fraction)÷(natural number), allowing us to scrutinize their attending, interpreting, and responding skills in detail. The study's results revealed that teachers demonstrated a tendency to attend mathematically significant aspects related to the teaching of fraction division. They interpreted the observed phenomena through the lens of fraction division's instructional principles, proposing specific pedagogical alternatives. These findings offer valuable insights for mathematics teacher education research.

In this study, we investigated the preservice elementary school teachers' self-images of science teaching and the factors influencing their formation by using Draw-A-Science-Teacher-Test Checklist (DASTT-C). One-hundred eighty-two sophomores and 183 seniors were selected from the departments of science and non-science education in three national universities of education. DASTT-C was administered to the sophomores at the beginning of the Spring Semester, and to the seniors at the beginning of the Fall Semester. Analyses of the results revealed that the self-images of science teaching of the seniors were more student-centered than those of the sophomores in the department of science education. However, there was no significant difference between the DASTT-C scores of the sophomores and the seniors in the department of non-science education. Many sophomores answered that the main factors affecting their self-images of science teaching were teaching-learning experiences in elementary, middle and high schools. However, many seniors cited the content and teaching methods in science education courses as well as direct or indirect teaching-learning experiences in teaching practices regardless of the departments. Educational implications of these findings are discussed.

The purposes of this research were as follows : (1) to investigate the effectiveness of the program for elementary preservice teachers, which was designed to develop postmodern views of science and constructivist views of teaming and teaching and (2) to find out the relation between students' learning approaches and their beliefs about science and school science. One hundred and forty three students enrolled in Science Education 11 in the University of Education participaled in the study. Students' beliefs of science and school science was not changed after treatment of the program. But they showed postmodern views of science and school science in comparison with the science teacher. Additionally the results showed that meaningful learners showed the constructivist view about school science as compared with the rote learners.

Six preservice teachers who participated in the "2016 service of summer vacation daycare programs by university and college students" focused on the programs for the formation of art, music and physical education and recreation culture were selected as research participants. The meaning of the experience they had through the service process was qualitatively analyzed. The subjects accepted the purpose of the self-directed service in which they should themselves solve a series of the entire process, from planning a volunteer program through drawing up the budget and purchasing materials to practice, evaluation and expressed the intention of participation. A volunteer program was conducted including visiting a daycare program for lower graders of elementary school (1st and 2nd grades) with more than 40 class hours during vacation. As research materials, research participants' journals, transcripts of individual interviews and group interviews, transcripts of phone calls, e-mail messages, and self-evaluation records of each class hour were collected. To increase the reliability and validity of the study, triangulation, member check, advice and review of the experts were conducted. In the study results, the volunteering experience-related significance for the preservice teachers who participated in the self-directed service were broadly categorized into 'Becoming a capable professional teacher', that consists of 'Increasing the power of thinking', 'Realizing the importance of communication', 'Doing together itself is important' and 'Ability to apply information and resources is needed'. 'Increase the continuity between preschool and elementary education' was subdivided into 'Get to know the necessity of the continuity between preschool and elementary education' and 'Want to learn the continuity between preschool and elementary education.'

The purpose of this study was to investigate preservice elementary school teachers' views on the relationship between science/technology and society. Freshmen (n=93) and seniors (n=82) at three universities of education were asked to express their views with 8 items in the Views On Science-Technology-Society, which consisted of two subcategories; 'influence of science/technology on society' (4 items) and 'influence of society on science/technology' (4 items). Mann-Whitney U test revealed that the scores of the freshmen were higher than those of the seniors. This trend was notable particularly in the item concerning 'influence of corporations on science/technology' and 'influence of interest groups on science/technology'. In comparing the scores by gender, a significant difference was found in the item concerning 'influence of policy on science/technology' for the freshmen.

This study examined the relationship between preservice teachers' mathematical understanding and problem posing in fractions multiplication and division. To this purpose, 41 preservice teachers performed visual representation and problem posing tasks for fraction multiplication and division, measured their mathematical understanding and problem posing ability, and examined the relationship between mathematical understanding and problem posing ability using cross-tabulation analysis. As a result, most of the preservice teachers showed conceptual understanding of fraction multiplication and division, and five types of difficulties appeared. In problem posing, most of the preservice teachers failed to pose a math problem that could be solved, and four types of difficulties appeared. As a result of cross-tabulation analysis, the degree of mathematical understanding was related to the ability to pose problems. Based on these results, implications for preservice teachers' mathematical understanding and problem posing were suggested.

This study systematically examined the influence of preservice teachers' self-efficacy and AI anxiety, on the intention to use AI programs 'knock-knock! mathematics expedition' in mathematics lessons based on a technology acceptance model. The research model was established with variables including self-efficacy, AI anxiety, perceived ease of use, perceived usefulness, and intention of use from 254 pre-service teachers. The structural relationships and direct and indirect effects between these variables were examined through structural equation modeling. The results indicated that self-efficacy significantly affected perceived ease of use, perceived usefulness, and intention to use. In contrast, AI anxiety did not significantly influence perceived ease of use and perceived usefulness. Perceived ease of use significantly affected perceived usefulness and intention to use and perceived usefulness significantly affected intention to use. The findings offer insights and strategies for encouraging the use of 'knock-knock! mathematics expedition' by preservice teachers in mathematics lessons.

The purpose of the study is to investigate how children and preservice teachers would make a progress in solving the open-problems related to area. In knowledge-based information age, information inquiry, information construction, and problem solving are required. At the level of elementary school mathematics, area is mainly focused on the shape of polygon such as square, rectangle. However, the shape which we need to figure out at some point would not be always polygon-shape. With this perspective, many open-problems are introduced to children as well as preservice teacher. Then their responses are analyzed in terms of their logical thinking and their understanding of area. In order to make students improve their critical thinking and problem solving ability in real situation, the use of open problems could be one of the valuable methods to apply.
