The purpose of this study is to analyze the stress experienced by pre-service chemistry teachers during their teaching practice. To do this, a stress test tool for pre-service science teachers was developed, and a survey was conducted with 19 pre-service chemistry teachers to investigate their anticipated stress before the practice and the stress experienced after the practice. The survey, conducted online before and after the teaching practice, was analyzed using descriptive statistics. The interpretation of the stress test results for pre-service chemistry teachers was based on teaching portfolios and interview data compiled during the teaching practice. The research findings are as follows: First, pre-service chemistry teachers anticipated various stresses before the teaching practice, but the number of stress factors and the number of pre-service teachers experiencing stress were generally lower during the practice. Second, there are a difference in the factors and percentage of anticipated and experienced stress before and during the teaching practice depending on the school level where pre-service chemistry teachers gained their practice. Third, there was no gender difference in the stress experienced by pre-service chemistry teachers during the teaching practice.

With the proven benefits of and increased interest in using technology in education, the role of teachers has become more important in integrating technology into mathematics classroom. Thus, it is important to improve preservice teachers' technological, pedagogical, and content knowledge (TPACK), which are influenced by their beliefs. This study examines how preservice secondary mathematics teachers' experience and beliefs related to technology use in the mathematics classrooms impact their TPACK. The results of this study show that preservice teachers who have more experience using technology and who hold student-centered beliefs towards technology use display higher levels of technology-related knowledge than preservice teachers who have little experience and who hold teacher-centered beliefs. Understanding the relationships between preservice teachers' TPACK and beliefs provides insights into how teacher education programs can support preservice teachers to develop TPACK and integrate technology into their future mathematics instruction.

The purpose of this study is to analyze how pre-service teachers perceive mathematics problems by making good mathematics problems at the elementary school level and applying them to elementary school students. In this study, 86 pre-service teachers enrolled in the second and third grades of A University of Education presented good mathematics problems they thought of. In addition, these pre-service teachers predicted the solution strategies of elementary school students for the proposed mathematics problem and described the teacher's expertise while observing the problem-solving process of elementary school students. As a result of the study, pre-service teachers preferred mathematical problems needed for using mathematical concepts or algorithms, motivation, and open-ended problems as good mathematics problems, and thought that students' in-depth observation and analysis experiences could help improve teachers' problem-solving expertise. In order to enhance teachers' expertise in solving mathematics problems, the researcher proposed for pre-service teachers to observe students' mathematics problem-solving processes, to experience in developing high-quality mathematics problems, and also to distribute high-quality mathematics problems linked to textbook problems.

With the advancement of digital technology, a variety of digital materials are being utilized in education. For their appropriate use of digital resources, teachers need to be able to evaluate the quality of digital resource and determine the suitability for teaching. This study explored how preservice teachers evaluate TocToc-Math, an Artificial Intelligence (AI)-based math support system. Based on an evaluation framework developed through prior research, preservice teachers evaluated TocToc-Math with evidence-based criteria, including content quality, pedagogy, technology use, and mathematics curriculum alignment. The findings shows that preservice teachers positively evaluated TocToc-Math overall. The evaluation tendencies of preservice teachers were classified into three groups, and the specific characteristics of each factor differed depending on the group. Based on the research results, we suggest implications for improving preservice teachers' evaluation abilities regarding the use of digital technology and AI in mathematics education.

This study explores the impact of a flipped classroom, in terms of self-efficacy, for elementary pre-service teachers in US teacher education programs. This research project explores how ESL microteaching activity in the flipped classroom shapes teacher-candidates' self-efficacy regarding teaching culturally and linguistically diverse (CLD) students. By analyzing ESL microteaching videos, pre-service teachers' reflection papers, and individual interviews with the course instructors, the study results show how pre-service teachers enhance their self-efficacy in teaching CLD English language learners in mainstream content subject classrooms. Moreover, the researchers provide suggestions on how teacher educators can utilize the flipped classroom to create an authentic and meaningful learning experience, such as using ESL microteaching for pre-service teachers to shape their self-efficacy in order to be well-prepared for CLD English language learners. The implication is that Korean pre-service teachers should be prepared to teach CLD students in their mainstream classrooms.

Although teacher preparation programs are important for prospective teachers to build a foundation of teaching expertise, there has been lack of research in this area. This paper analyzed in what ways prospective teachers' ability in describing and commenting on elementary mathematics instruction has been changed while they were taking in the course of teaching elementary school mathematics. The results of this study showed that in late description the teachers tended to notice the core flow of a lesson and the use of instructional strategies appropriate to the mathematical content to be taught. They also tended to comment on instructional strategies and mathematical discourse from the teacher's perspective and evaluated them without alternative approaches. A noticeable change occurred in late comments wherein prospective teachers considered both the teacher and students, supported their comments by theories they had learned through the course, and interpreted the classroom events they had noticed. Building on these results, this paper closes with implications of teacher education programs to enhance prospective teachers' ability to analyze elementary mathematics lessons.
