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 learning environment at mathematics education, prove and refute are essential abilities to demonstrate whether and why a statement is true or false. Learning proofs and counter examples within the domain of limit of sequence is important because preservice teacher encounter limit of sequence in many mathematics courses. Recently, a number of studies have showed evidence that pre service and students have problem with mathematical proofs but many research studies have focused on abilities to produce proofs and counter examples in domain of limit of sequence. The aim of this study is to contribute to research on preservice teachers' productions of proofs and counter examples, as participants showed difficulty in writing these proposition. More importantly, the analysis provides insight and understanding into the design of curriculum and instruction that may improve preservice teachers' learning in mathematics courses.

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.

It has recently be emphasized in science education that lessons that can develop "scientific participation and action" should be implemented to scientifically recognize various problems and respond to them as well as risks that occur in real life. This study aims to analyze the characteristics of scientific participation and action lessons as perceived by the preservice primary school teachers. To do that, the researchers collected and analyzed the lesson plans designed by the preservice teachers based on the achievement standard related to noise for grades 3-4 in 2022 revised science curriculum. Focusing on the stages of "problem recognition," "data collection and analysis," and "implementation and sharing," the results identity the four main characteristics as problem-solving activity, inquiry activity, investigative activity, and activity that encourages practical actions. The two or three features were found to be combinated in a lesson depending on its context. In some cases, only one feature was seen in a lesson. Based on the results, educational implications were discussed in terms of the teaching and learning methods and teacher education for implementing scientific participation and action.

While great efforts are being exerted on the reform of teacher training to provide integrated use of ICT in a teaching-learning process with educational informatization, it is still indicated that a teachers' training school fails to prepare leachers for incorporating information Communication and Technology (ICT) properly into an instructional process. Based on this awareness, this study aims at examining and analyzing the ability level of In utilization training for preservice teachers and thus at providing basic data to perform ICT utilization teaching-learning according to the seventh curriculum in a school. For this purpose, a survey was conducted with preservice teachers (seniors) in a college of education, Kongju National University and the collected data were analyzed using a Statistical Package for the Social Science (SPSS) 12.0 program.

164 preservice elementary teachers' decision and enactment of their knowledge of fraction multiplication were examined in a context where they were asked to write a story problem for a multiplication problem with two proper fractions. Participants were selected from an entry level course and an exit level course of their teacher preparation program to reveal any differences between the groups as well as any recognizable patterns within each group and overall. Patterns and tendencies in writing story problems were identified and analyzed. Implications of the findings for teaching and teacher education are discussed.

The purpose of this study was to examine the meaning of the diverse experiences of preservice early childhood teachers during their participation in a career portfolio production program. A career portfolio production program was implemented during a nine-week period of time, and data were gathered to explore the meaning of their experiences in that process, which involved their journals, the report of their coaching professor and small- group interview data. The collected data were analyzed by encoding. As a result of analyzing the data, their experiences were categorized into eight categories: perceiving the flow of time, gathering scattered experiences, finding oneself amid chaos, being aware of being together, building psychological wellbeing, imagining one's own future as an early childhood teacher, mapping out one's future and making one's way to the world. The meanings of their experiences were reclassified into three stages: beginning, development and wrapping-up stages, in which there were two, four and two meanings respectively. The findings indicated that they were mostly cognizant of the meaning of their own experiences of producing career portfolio while they participated in the program step by step.

Teaching is delicate, complicated, and demanding work, and especially beginning teachers set forth their difficulties in preparing and implementing mathematics instruction. It is important to ensure the quality of beginning mathematics teachers' instruction above a consistent level because such affirmation justifies the national policy on teacher education as well as the individual efforts of preservice teachers in South Korea. The current study collected mathematics lessons of the two beginning teachers who graduated from the same teacher training institute and worked at the same high school. The findings reported what features their lessons have with regard to the learning environment, engaging students in learning, deepening student learning, and using representations of the edTPA in order to identify what can or cannot be expected in their mathematics instruction. The instruction of the one teacher was assessed middle or more than middle scores throughout the rubrics, but the other one had lower scores. Based on these findings, this study suggested the implications for teacher education in ways of improving the quality of instruction of beginning mathematics teachers.

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.

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.
