In this case study, we investigated the characteristics of secondary beginning science-gifted education teachers' reflection on their science teaching with coteaching through mentoring. We selected two beginning teachers with less than one year teaching careers in secondary science-gifted education. The teachers planned, performed, and reflected together on their science teaching for science-gifted students during twelve class hours over four times. Since the second class, pre-, during-, and post-mentorings were conducted. We observed their science classes with coteaching through mentoring, and analyzed their reflective journals in the views of productive reflection. The analyses of the results revealed that 'instructional strategies and instruction for science-gifted education' and 'science-gifted students' were most frequently included in their reflection regardless of class time. 'Curriculum for science-gifted education' were also frequently included although fewer than the two aspects. However, 'subject matter knowledge' and 'assessment in science-gifted education' were hardly included. Two to four aspects of the five were variously integrated in their reflection. The integrations among three to four aspects were especially more frequently included than those between two aspects. The integrations of 'instructional strategies and instruction for science-gifted education' or 'science-gifted students' with the other aspects were also found to be the most frequent. These results suggest that coteaching through mentoring can promote beginning science-gifted education teachers' productive reflection on their science teaching.

This study investigated elementary preservice teachers' conceptions of a generating line, an ambiguous concept in school mathematics. The preservice teachers' conceptions of a generating line can be classified into four types: (a) only cones have generating lines, (b) only cones and cylinders have generating lines, (c) solids of revolution have generating lines, (d) straight lines on the lateral surface are generating lines. 22.1% of all preservice teachers believed that only cones have generating lines, and most of them followed the definition of a generating line presented in elementary mathematics textbooks. The conception that only cones and cylinders have generating lines was the least investigated. However, since there were instances where generating lines were defined with the use of a director curve, it became important to explore topics more thoroughly, such as generating lines of a truncated cone. 27.9% of all preservice teachers believed that solids of revolution have generating lines. This conception was marked by differing opinions on whether spheres also have generating lines. The conception that straight lines on the lateral surface are generating lines was the most frequently investigated. This conception differs from the traditional view in school mathematics because it suggests using a director curve to define generating lines. Based on these analysis results, the researcher developed specific teaching methods that considered both subject matter knowledge and pedagogical content knowledge for preservice teachers. In addition, the researcher proposed a consensus definition of a generating line in mathematics education.

This thesis presents the 'Information and the Library' curriculum and the roles of teacher-librarians. Related to 'The School Library Promotion Law', this thesis presents the effects teacher-librarians instruct 'Information and the Library' curriculum to the school libraries, and the challenges related to this curriculum. This thesis contains the role and work of three kinds of staff in the school library. implementation of primary and secondary 'Information and the Library' curriculum for information literacy instruction in the school libraries, the effects by 'Information and the Library' curriculum. and challenges of 'Information and the Library' curriculum. Conclusively, teacher-librarians should accomplish their own instructional activities with 'Information and the Library' curriculum in the school curricula as differentiated work from librarians.

This study aims to describe, explain, and understand the process of coteaching instruction in which two pre-service science teachers plan, perform, and reflect the instruction in a university lecture. Pre-service science teachers exchanged their perspectives on teaching, selected the learning model and the science content to teach, and prepared the teaching material together. They performed the coteaching using the lecture room effectively and exchanging the role of leading the instruction. The professor and other pre-service science teachers participated to the coteaching instruction directly or indirectly with the role of students or lesson critics, and shared the evaluation and reflection on the instruction. We discussed the meaning and implication of the coteaching instruction on the secondary education field, the science teacher education, and the science education.

The purpose of this study was to develop an inquiry-based professional development program for in-service secondary science teachers and to investigate it's application. The inquiry-based professional development program was reconstructed based on SSCS problem-solving model, which is composed of 4 stages of search, solve, create, and share. The 28 science teachers' understanding of the SSCS program were investigated as implementing the program. As a result of this study, 8 SSCS modules have developed as the science teachers have searched, solved, created, and shared various situated problems. The science teachers found themselves to have positive perception of SSCS program. The SSCS program was effective in changing the learners' teaching/learning attitude and to develop individual scientific thinking. To make the SSCS problem solving successful and more effective, both science teachers' professionalism and pedagogical knowledge for selecting topic as the levels of learner should be considered.

This study reflects the regional context of Northeast Asian countries embodied in US-North Korean nuclear tension. The researcher uses the methodological inquiry of practical theology to analyze the political affairs and intertwine with religious education. The ecology of religious education to dismantle the threat of ethnic and racial discrimination such as white supremacy supports a shared pedagogy between students and their teachers in the narrative of Jesus to challenge all forms of oppression as the democratic presence of God.

This study was conducted to confirm the mediating effect of the teacher's trust in the relationship between the classroom teacher's transformative leadership and the students' emotional stability from the organizational perspective. For this, the data from 290 middle school students in Seoul were collected and analyzed. As a result of the study, the transformative leadership of the homeroom teacher had a positive (+) effect on the trust of the leader. In addition, the teacher's trust in the leader had a positive (+) effect on the learner's emotional stability. In addition, it was confirmed that the teacher's transformational leadership had a positive (+) effect on the learner's emotional stability. Finally, in the relationship between the homeroom teacher's transformative leadership and the learner's emotional stability, teacher trust has a partial mediating effect. This study is meaningful in that it has objectively verified what kind of leadership the homeroom teacher should aim for in order to operate the classroom as the peripheral unit of the school organization, and what emotional and psychological effects such leadership can have on students who are members of the organization.

The purpose of this study is to explore the possibility of enhancing teachers' pedagogical design capacity using ChatGPT. For this purpose, a survey was conducted to investigate preservice teachers' perceptions of ChatGPT, and lesson plans created using ChatGPT were analyzed from the perspectives of design elements, conversations with ChatGPT, and information transforming. The results showed that pre-service teachers have a rather passive attitude toward the use of ChatGPT, and that teacher moderation and ChatGPT characteristics affect pre-service teachers' perceptions of the use of ChatGPT. In addition, pre-service teachers mainly used ChatGPT for motivational activities and play activities, and there were significant differences in the level of utilization of ChatGPT among individuals, i.e., how they interacted with ChatGPT and how they transformed information. Based on these findings, we explored the possibility of using ChatGPT for teacher professional development and teacher education.

In this paper we investigated the types of the explanatory consistency of preservice secondary teachers in explaining the lunar phase. The explanatory consistencies were proposed into four discrete mental models depending on their attributes. The four types based on the explanatory consistency by the preservice secondary teachers' explanations are as follows: ad hoc expansion, competitive theory addition, transition of unexplainable each, and transition using in context of several situations.
